History Debunked Refutes Ethnomathematics/Rehumanizing Mathematics

September 8, 2020

This is another video from History Debunked. In it, youtuber and author Simon Webb attacks Ethnomatics, sometimes also called Rehumanizing Mathematics. This is a piece of modern pseudo-scholarship designed to help Black children tackle Maths. The idea is that Blacks perform poorly compared at Maths compared to other ethnic groups. This is held to be because Maths is the creation of White men, and this puts Blacks off studying and mastering it.

The solution has been to scrutinise African societies for their indigenous Maths, especially the Dogon of Mali. They have been chosen as the chief model for all this, as they possessed extremely advanced astronomical and mathematical knowledge. In the 1970s there was a book, The Sirius Mystery by Robert K.G. Temple, which claimed that they owed this advance knowledge to contact with space aliens. Apparently this claim was subsequently dropped 10 – 15 years later, and the claim made instead that they were just superlative astronomers and mathematicians themselves. But Dogon Maths is held to be different from White, western Maths because it’s spiritual. History Debunked then goes on to demonstrate the type of pseudo-scientific nonsense this has lead to by providing a link to an Ethnomathematics paper and reading out its conclusion. It’s the kind of pretentious verbiage the late, great Jazzman, Duke Ellington, said stunk up the place. It’s the kind of postmodern twaddle that Sokal and Bricmont exposed in their Intellectual Impostures. It’s deliberately designed to sound impressive without actually meaning anything. There’s a lot of talk about expanding cognitive horizons and possibilities, but History Debunked himself says he doesn’t understand a word of it. And neither, I guess, will most people. Because it doesn’t really mean anything. It’s just there to sound impressive and bamboozle the reader into thinking that somehow they’re thick because they don’t, while the fault is entirely the writers.

I think History Debunked is a man of the right, and certainly his commenters are Conservatives, some with extremely right-wing views. He’s produced a series of videos attacking the pseudo-history being pushed as Black History, and apparently Seattle in America is particularly involved in promoting this nonsense. But he expects it to come over here in a few years. Given the way Black History month has jumped the Atlantic, I think he’s right.

There’s been a particular emphasis on find ancient Black maths and science for some time I know. For a brief while I got on well with a Black studies group when I was a volunteer at the slavery archives in the former Empire and Commonwealth Museum. That was before I read their magazine and got so annoyed with it and its attitude to Whites that I sent them a whole load of material arguing to the contrary, and pointing out that in places like the Sudan, Blacks were being enslaved and oppressed not by White Europeans, but by the Arabs. I also sent them material about the poor Whites of South Africa, who also lived in grinding poverty thanks to Apartheid. This was stuff they really didn’t want to hear, and I was told that if I wanted to talk to them further, I should do so through someone else. They were also interested in finding examples of Black maths and science. I sent them photocopies and notes I’d made of various medieval Muslim mathematicians. These were Arabs and Persians, like al-Khwarizmi, who gave his name to the word algorithm, Omar Khayyam, best known in the west for his Rubayyat, but who was also a brilliant mathematician, al-Haytham, who invented the camera obscura in the 12th century and others, rather than Black. But they were grateful for what I sent them nonetheless, and I thanked me. This was before I blotted my copybook with them.

I’m reposting this piece because, although it comes from the political, it is correct. And you don’t have to be right-wing to recognise and attack this kind of postmodern rubbish. Sokal and Bricmont, the authors of the book I mentioned early attacking postmodernism, were both men of the left. Sokal was a physicist, who taught maths in Nicaragua under the left-wing Sandinista government. They wrote the book because they took seriously George Orwell’s dictum that writing about politics means writing clearly in language everyone can understand. And even if you believe that Black people do need particular help with maths because of issues of race and ethnicity, Ethnomathematics as it stands really doesn’t appear to be it. It just seems to be filling children’s heads with voguish nonsense, rather than real knowledge.

I also remember the wild claims made about the Dogon and their supposed contact with space aliens. Part of it came from the Dogon possessing astronomical knowledge well beyond their level of technology. They knew, for example, that Sirius has a companion star, invisible to the naked eye, Sirius B. They also knew that our solar system had nine planets, although that’s now been subsequently altered. According to the International Astronomical Association or Union or whatever, the solar system has eight planets. Pluto, previously a planet, has been downgraded to dwarf planet, because it’s the same size as some of the planetoids in the Kuiper Belt. Lynn Picknett and Clive Prince discuss this in one their books,The Stargate Conspiracy (London: Little, Brown & Company 1999), which claimed that the American intelligence agencies were secretly preparing a fake UFO landing in order to convince everyone that the space gods really had arrived, and set up a one-world dictatorship. This hasn’t happened, and I’ve seen the Fortean Times and other weird magazines trying to explain their book as a high-level hoax which people took too seriously. I don’t believe this, as they seemed very serious at the time. The Dogon believe that the first human ancestors, and some of their gods, came from the sky. Hence Temple’s claim that they were contacted by space aliens. Picknett and Prince, however, sided with sceptics like Carl Sagan. They argued instead ithat the Dogon owed it to a French priest, anthropologist or colonial administrator, I’ve forgotten which, who visited them in the 1920s and who was extremely interested in astronomy. This seems to me to be far more likely than that they either got it from space aliens or that they far better mathematicians and astronomers than they could have been at their level of development.

The Dogon are fascinating as their homes and villages are laid out to be microcosms of the male and female human body and the universe. The book African Mythology by Geoffrey Parrinder, London: Hamlyn 1967, describes the layout of a Dogon house thus:

The shape of the Dogon house is symbolical. The floor is like the earth and the flat roof like heaven. The vestibule is a man and the central room woman, with store rooms at her sides as arms. The hear at the end is her head. The four posts are the man and woman entwined in union. So the family house represents the unity of man and woman and God and the Earth. This is accompanied by the elevation and ground plan of a typical Dogon house. (p. 49).

There’s also this diagram of an idealised Dogon village:

The caption for the diagrame reads:

Like the house, the Dogon village represents human beings. The smithy is at the head like a hearth in a house. The family houses in the centre and millstones and village represent the sexes. Other altars are the feet. (p. 51).

Truly, a fascinating people and I have no problem anybody wanting to study them. But it should be in anthropology, ethnography or comparative religion, not maths.

But it struck me that if teachers and educators want to enthuse and inspire young minds with what maths Africans were studying, they could start with ancient Egypt and the great Muslim civilisations of the Sahara and north Africa, like Mali. Aminatta Forna in one of her programmes on these civilisations was shown an ancient astronomical text from the medieval library of one of these towns, which she was told showed that Muslims knew the Earth orbited the sun before Copernicus and Galileo. I doubt that very much. It looks like a form of a combined helio-and geocentric system, first proposed by the ancient Greeks, and then taken up by some medieval astronomers not just in Islam, but also in Christian Europe. In this system, all the other planets when round the Sun, which orbited the Earth. Close to the modern system, but not quite. But it showed that the Black citizens of that civilisation were in contact with the great currents of Muslim science, and that they would have had learnt and taught the same kind of Maths that was being investigated and researcher right across the Muslim world, from India to Morocco and further south to Mali. One of the Black educationalists would like to translate one of these books from Arabic, the learned language of Muslim civilisation, and use it as an example of the kind of maths that was also taught in Black Africa.

Or you could go right back to ancient Egypt. Mathematical texts from the Land of the Nile have also survived in the Moscow and Rhind mathematical papyri. These have various maths problems and their solution. For example, problem No. 7 of the Moscow papyrus is about various calculations for a triangle. This runs

Example of calculating a triangle.

If you are told: A triangle of 2 thousands-of-land, the bank of 2 of 2 1/2;

You are to double the area: result 40 (arurae). Take (it) 2 1/2 times; result [100. Take its square root, namely] 10. Evoke 1 from 2 1/2; what results is 2/5. Apply this to 10; result 4. It is 10 (khet) in length by 4 (khet) in breadth. From Henrietta Midonick, The Treasury of Mathematics: 1 (Harmondsworth: Pelican 1965) p. 71.

It’s amazing to think that the boys at the scribal school were being taught all this millennia ago. It gives you a real sense of connection with the ancient schoolkids reading it. You can imagine them, hunched over with their pen and ink, busily cudgeling their brains while the teacher prowls about them. The Babylonians were also renowned as the pioneers of early mathematics. They even uncovered a school when they excavated Ur of the Chaldees in the 1920s, complete with the maths and other texts the schoolboys – female education didn’t exist back then, but I’m willing to be corrected – were required to learn. As a schoolboy character in the Fast Show used to say: ‘Brilliant!’ You don’t need to burden modern African societies like the Dogon with spurious pseudo-history and pseudo-science, when the real historic achievements of ancient Egypt and medieval Africa are so impressive.

It struck me that even if you don’t use the original Egyptian maths texts to teach maths – which would be difficult, as their maths was slightly different. Their method of calculating the area of a field of four unequal sides yields far too high a figure, for example – you could nevertheless inspire children with similar problems. Perhaps you could do it with assistance of a child or two from the class. You could bring them out in front of everyone, give them and ancient Egyptian headdress, and then arranged the lesson so that they helped the teacher, acting as pharaoh, to solve it. Or else pharaoh showed them, his scribes, and thus the class. This is certainly the kind of thing that was done when I was a kid by the awesome Johnny Ball on the children’s maths and science programme, Think of a Number. And every week, as well as showing you a bit of maths and science, he also showed you a trick, which you could find out how to do by dropping him a line. It was the kind of children’s programme that the Beeb did very, very well. It’s a real pity that there no longer is an audience for children’s programmes and their funding has subsequently been cut.

Here’s History Debunked’s video attacking Ethnomathematics. He also attacks a piece of ancient baboon bone carved with notches, which he states has been claimed is an ancient prehistoric African calendar. He provides no evidence in this video to show that it wasn’t, and says its the subject of a later video. If this is the one I’m thinking of, then that is a claim that has been accepted by mainstream archaeologists and historians. See Ivor Grattan-Guinness, The Fontana History of the Mathematical Sciences (London: Fontana Press 1998) p. 24.

If you want to know more about ancient and medieval maths, and that of the world’s many indigenous cultures, see the book Astronomy before the Telescope, edited by Christopher Walker with an introduction by the man of the crumpled suit and monocle himself, Patrick Moore (London: British Museum Press 1998).

This has chapters on astronomy in Europe from prehistory to the Renaissance, but also on astronomy in ancient Egypt, Babylonia, India, Islam, China, Korea and Japan, North and South America, traditional astronomical knowledge in Africa and among Aboriginal Australians, Polynesia and the Maori. It can be a difficult read, as it explores some very technical aspects, but it is a brilliant work by experts in their respective fields.

BBC 2 Programme Next Week on Possibility of Life on Pluto

July 2, 2020

Way back in the 1970s David Bowie as Ziggy Stardust asked if there was life on Mars. Things have advanced since then, and a new programme on BBC 2 next Monday, 6th July 2020, ponders the possibility that life might exist on the dwarf planet traditionally at the edge of our solar system: Pluto. From being a dead world, Pluto is geologically active and possesses organic chemistry, the building blocks of life. Which raises the question of whether life of some sort exists there.

The programme’s titled Pluto: Back from the Dead and the  blurb for it on page 62 on next week’s Radio Times for 4th – 10th July 2020 reads

New discoveries from the edge of the solar system are transforming what is known about Pluto, thanks to the New Horizons space probe that took the first-ever close up images of the dwarf planet. This Horizon documentary reveals that Pluto, once thought to be geologically dead, is an active world of stunning complexity, with mountains carved from ice, a nitrogen glacier that appears to be moving and a recently active volcano. The data sent back has led some scientists to speculate that there may even be life on Pluto today.

David Butcher’s piece about the programme on page 60 adds

There might be life on Pluto. It sounds far fetched, but that’s the conclusion some scientists have reached, and its one of the unexpected new angles explored in this intriguing edition of Horizon.

The insights come courtesy of New Horizons, a tiny spacecraft that travelled 3.26 billion miles to the edge of the solar system, and sent back amazingly detailed imagery.

It reveals a geologically fertile world with, among other features, a nitrogen glacier and a recently active volcano. Moreover, Pluto’s abundant supply of organic molecules and liquid water suggest some form of alien life might exist.

Pluto isn’t alone in possessing mountains of ice. They also exist on Titan and the other moons of the outer solar system. Titan also possesses organic chemistry, which is why scientists are particularly interested in it for clues about the origin of life on Earth. And it was also at one considered that it too may have life. Carl Sagan also suggested that it might even have volcanoes of frozen gas. There’s an illustration of Titan with one such volcano erupting by the astronomy/science Fiction artist David A. Hardy in his and Patrick Moore’s The New Challenge of the Stars. I don’t know if such volcanoes actually exist there. I haven’t seen anything about the Huygens probe to Saturn and its moons finding any.

Scientists also began speculating that life might also exist in the frozen wastes of the outer solar system after someone suggested that the difference of a few degrees’ temperature between light and shadow on them might be enough to provide the energy to drive life. The quantum physicist and SF author Stephen Baxter expanded this into a short story in his Xelee sequence, collected in the his short story anthology, Vacuum Diagrams. I think that story, however, was set further out in one of the dwarf planets of the Kuiper Belt.

After all this time searching the solar system, I think it’s extremely unlikely that there’s life on Pluto. But who knows, perhaps I’m wrong. It would be truly epoch-making if I was and Pluto did possess a biosphere, even if it was only simply microbial organisms.

The programme’s on BBC 2 at 9.00 pm on Monday, 6th July.


Rachel Riley’s Awesome Scientific Knowledge

October 17, 2019

Rachel Riley, the Z-list TV celebrity suing Mike and 15 others for libel, ’cause he reblogged material showing her bullying a sixteen year old schoolgirl, has appeared in Private Eye. More specifically, she’s in their ‘Commentatorballs’ column for a fine display of scientific ignorance. They quote her as saying

“Popular science has come a long way. I think Brian Cox has done amazing things for astrology.”

Apparently, she made this startling pronouncement on Radio 3. This would have irritated the late Patrick Moore, the former Presenter of the Sky At Night and author of countless books on astronomy and space. As Moore used to point out, astrology is the pseudoscience which claims that the positions of the stars and planets influences events on Earth. It’s astronomy, which is the scientific study of the stars, planets and space. Brian Cox has indeed done amazing things poplarising science and astronomy. The distinction between astronomy and astrology, however, has gone over Riley’s head.

As has the fact that criticising Israel and its persecution of the Palestinians does not make you an anti-Semite. And nor does smearing those, who do criticise Israel, or accusing them of libel when they stand up to you, make you popular. 

‘I’ Newspaper: NASA Planning Permanent Return to the Moon

February 12, 2019

Before the deep political stuff, a piece of space news. According to yesterday’s I for 11th February 2019, NASA is planning to go back to the Moon and found permanently manned bases. The article by Clark Mindock, ‘NASA wants to station humans on the Moon’ on page 23 ran

NASA is planning to send astronauts to the Moon again, but this time it wants to keep them there.

The US space agency’s administrator, Jim Bridenstine, called yesterday for “the best and brightest of American industry to help design and develop human lunar landers”, in response to what he said was a clear mandate from President Donald Trump and Congress to once again get astronauts out of Earth’s orbit.

In a post detailing Nasa’s lofty goals – to return astronauts to the Moon, and one day send them to Mars for the first time in human history – Mr Bridenstine said that the US was playing for keeps this time.

“I am thrilled to be talking once more about landing humans on the Moon,” he wrote on the Ozy website.

“To some, saying that we are returning to the Moon implies that we will be doing the same as we did 50 years ago. I want to be clear – that is not our vision.

“We are going to the Moon with innovative new technologies and systems to explore more locations across the surface than we ever thought possible. This time, when we go to the Moon, we will stay.”

Mr Bridenstine said that the ambitious plans would begin later this week, with partners from private industry and elsewhere invited to NASA headquarters in Washington DC to discuss the next generation of lunar landers.

So far, Nasa has already co-operated with nine companies to send cargo tot he Moon, with the ultimate goal being to develop landers that can take astronauts back there.

As a space fan, all I can say is that it’s about time. Way back in the 1970s and 1980s space experts and commenters, like Sir Patrick Moore, the presenter of the Sky At Night, were predicting that we’d have bases on the Moon and elsewhere in solar system by now. But that was before space budgets were drastically cut and NASA instead concentrated on the Space Shuttle. This was supposed to open space up to just about anybody who could afford the cost of a ticket and was in reasonable health. Its crews experienced 3Gs at lift-off, but this was considered to be so low that a 70-year old man could tolerate it. Unfortunately the Shuttle was massively overengineered and the Challenger disaster put the programme on hold while its causes were investigated and corrected. Even then its use remained risky, as we saw a few years ago when one disintegrated during re-entry over America and the programme was subsequently cancelled.

There were plans in the 1990s for a private, commercial return to the Moon, according to Focus Magazine, but that didn’t seem to get anywhere.

My guess is that NASA is finally getting round to putting a permanent human presence on the Moon not just because Trump fancies going back to the glory days of the Cold War space race, but because the EU and the Chinese are also planning the serious exploration of the Moon. A little while ago ESA – the European Space Agency – announced they were planning to put people on the Moon, while last week the Chinese successfully landed a probe on the Moon’s far side. The Chinese are putting such effort into their space programme that the quantum physicist and SF writer, Stephen Baxter, predicted back in the 1990s that the first person on Mars would probably be Chinese sometime in the next decade. Under Reagan, one of the big aerospace conglomerations and think tanks published a report arguing that America needed to develop its space technologies and industries, and move out onto the High Frontier, in order to secure its place as world leader. It’s likely that this is the same thinking behind this announcement by NASA.

As for exploring the next generation of lunar landers, I wonder if they’ll be able to use any data or blueprints remaining from the original lunar modules that landed Armstrong, Aldrin and co all those years ago. After the Apollo programme was cancelled, the massive Saturn 5 rockets were broken up, with the exception of those on display at the Kennedy Space Centre, and the plans destroyed. This has outraged many space scientists like John S. Lewis, the author of Mining the Sky, who compared it to the destruction of Chung He’s fleet by the Chinese eunuchs in the 14th century. Chung He was a Chinese admiral, who led a fleet of ships on an exploratory mission to the outside world, going as far as the Bight of Benin in West Africa. However, when he returned the eunuchs at the imperial court had his fleet destroyed and further exploration banned because they feared that opening the country up to foreign contact would have a destabilizing effect on its society. The result of this was that the country remained isolated and stagnated until it fell prey to foreign colonialism in the 19th century, most famously through the Opium Wars.

Hopefully NASA’s announcement will mark the beginning of a new, serious wave of interplanetary exploration which aims to put people on the Moon and other planets, as space scientists, engineers and SF fans and writers have been dreaming about and working towards since before the great German director Fritz Lang made his epic movie Die Frau im Mond (‘The Woman in the Moon’) about a German moon landing back in the 1920s.

The Sky At Night Looks at Britain in Space

October 19, 2018

I just managed to catch the weekday repeat a day or so ago of this month’s Sky at Night, in which presenters Maggie Aderin-Pocock and British astronaut Tim Peake looked at the history of Britain in space, and forward to the country’s future in the deep black. The programme’s changed a bit over the past few years in the case of its presenters. It was famously presented by Sir Patrick Moore from its beginning in the 1950s until he passed away a few years ago. This made the programme the longest-running show presented by the same person. Aderin-Pocock joined it before Moore’s departure. She’s a black woman scientist, with a background in programming missile trajectories. She’s obviously very intelligent, enthusiastic and very definitely deserves her place on the show. But I wish she’d done a job that didn’t involve the military use of rocket technology, however much this is needed as part of national defence.

Aderin-Pocock was speaking to one of the management officials from Orbex, a new, British company, which has developed a rocket launcher and intends to open a spaceport in one of the more deserted areas of Scotland. The rocket will stand about 17 meters tall, using propane and High Test Peroxide as fuel. High Test Peroxide is a highly concentrated version of the hydrogen peroxide used by hairdressers to bleach peoples’ hair. The use of propane is particularly important, as it’s lighter than conventional rocket fuels, meaning that the rocket doesn’t have to carry as much fuel to lift off into space. Advances in satellite design have also allowed the rocket to be smaller than other spacecraft used elsewhere. British universities have succeeded in developing microsatellites – satellites that are much, much smaller than some of the satellites put into orbit, but which can perform the same functions. As these satellites are smaller and lighter, they only need a relatively smaller, lighter rocket to launch them.

The Scottish launch complex also wasn’t going to be as big as other, larger, major launch complexes, such as those of NASA, for example. I think it would still contain a launch tower and control buildings. As well as the official from Orbex, the show also talked to a woman representing the rural community in the part of Scotland, where they were planning to build it. She admitted that there would be problems with building it in this part of the Scots countryside. However, the community was only going to lease the land, not sell it to Orbex, and care would be taken to protect the farms of the local crofters and the environment and wildlife. Like much of rural Britain, this was an area of few jobs, and the population was aging as the young people moved away in search of work. She looked forward to Orbex and its spaceport bringing work to the area, and creating apprenticeships for the local young people.

The programme went on to explain that this would be the first time for decades that a British company was going to build a British rocket to launch a British satellite. From what looked the British space museum in Manchester, Time Peake stood under the display of Britain’s Black Knight rocket and the Prospero satellite. He explained how the rocket launched the satellite into space from Australia in 1975. However, the project was then cancelled, which meant that Britain is the only country so far which has developed, and then discarded rocket technology.

But Black Knight wasn’t the only space rocket Britain developed. Peake then moved on to talk about Skylark, a massively successful sounding rocket. Developed for high altitude research, the rocket reached a maximum of altitude of 400 km in the few minutes it was in flight. At its apogee – its maximum distance from Earth – the vehicle briefly experienced a few minutes of zero gravity, during which experiments could be performed exploring this environment. The Skylark rocket was used for decades before it was finally cancelled.

Aderin-Pocock asked the official from Orbex how long it would be before the spaceport would be up and running. The manager replied that this was always an awkward question to answer, as there was always something that meant operations and flights would start later than expected. He said, however, that they were aiming at around the end of 2020 and perhaps the beginning of 2021.

Orbex are not, however, the only space company planning to open a spaceport in Britain. Virgin Galactic have their own plans to launch rockets in to space from Cornwall. Their vehicle will not, however, be launched from the ground like a conventional rocket, but will first be carried to a sufficiently high altitude by an airplane, which would then launch it. I’m not a betting man, but my guess is that of the two, Orbex is the far more likely to get off the ground, as it were, and begin launching its rocket on schedule. As I’ve blogged about previously, Branson has been telling everyone since the late 1990s at least, that Virgin Galactic are going to be flying tourists into space in just a few months from now. This fortnight’s Private Eye published a brief list of the number of times Branson had said that, with dates. It might be that Branson will at last send the first of his aspiring astronauts up in the next few months, as he claimed last week. But from his previous form, it seems far more likely that Orbex will start launches before him, as will Branson’s competitors over the pond, Elon Musk and Jeff Bezos.

When asked about the company’s capability of perfecting their technology, Orbex’s manager not stressed the skill and competence of the scientists, technicians and engineers working on the project. This included not just conventional space scientists, but also people, who had personally tried and failed to build their own spacecraft. He said that it was extremely important to fail to build rockets. He’s obviously referring to the many non-professional, hobby rocketeers out there trying to build their own spacecraft. He didn’t mention them, but one example would be the people at Starchaser, who started out as a small group of enthusiasts in Yorkshire but have gone on to create their own space company, now based across the pond in America. I think it’s brilliant that amateurs and semi-professionals have developed skills that the professionals in the industry find valuable. And the failures are important, as they show what can go wrong, and give the experience and necessary information on how to avoid it. I don’t think the rocket will be wholly built in this country. The manager said that some of it was being constructed in Copenhagen. This sounds like Copenhagen Suborbitals, a Danish team of rocket scientists, who are trying to put a person into space. They’re ex-NASA, I believe, but it’s a small, private venture. They have a webpage and have posted videos on YouTube, some of which I’ve reblogged. They’ve also said they’re keen for people to join them, or start their own rocket projects.

I’d been looking forward to that edition of the Sky at Night for the past week, but when the time came, it slipped my mind that it was on. I’m very glad I was able to catch it. If Orbex are successful, it will be the first time that a British satellite will launch a British satellite from here in Britain. And it sounds really optimistic. Not only will Britain be returning to space rocket development, but the Scots spaceport sounds like it will, hopefully, bring work to a depressed area. I’m also confident that the local environment there will also be preserved. The launch complex around NASA is necessarily so remote from other buildings, that it’s actually become a wildlife haven. So much so that it’s now a location for birdwatching.

When it was announced that they were planning to build a new spaceport in Scotland, I assumed it would be for Skylon, the British spaceplane. There had been articles in the paper about the spacecraft, which stated that it would be launched either from Scotland or Cornwall. It seems I was wrong, and that it’s Orbex’s rocket which will be launched there instead. But nevertheless, I wish Orbex every success in their venture, and hope that sometime soon Skylon will also join them in flight out on the High Frontier.

Percival Lowell: Martians Would Have Global Government to Fight Environmental Decline

October 6, 2018

Percival Lowell was the astronomer most responsible for popularizing the idea of Martian canals.

It was the Italian astronomer, Schiaparelli, who first claimed to have observed watercourses he called ‘canali’. The Italian word was translated ‘canals’, but it also means simply ‘channels’. And many astronomers regarded them simply as that, natural features. However, at the end of the 19th century many confidently believed that Mars was the home of intelligent life, though astronomers were increasingly aware that Mars was not as hospitable as Earth. They believed it was a planet of vast deserts. Lovell, an American astronomer with an observatory at Flagstaff, Arizona, was convinced that not only was there intelligent life on Mars, but that the Martians had a highly advanced civilization. They had constructed the canals he drew and mapped to bring water from their dying planet’s polar regions down to the equator to sustain life and civilization. He realized that the canals themselves would have been too small to observe from the Earth, but believed that the lines he saw were the surrounding tracts of lush, green vegetation, flourishing amid the encroaching Martian desert.

And he had a highly optimistic view of the moral progress of their civilization.

I found this brief passage quoting Lowell, and commenting on his view of the people of the Red Planet in The New Challenge of the Stars, by Patrick Moore and David A. Hardy, with a foreword by Arthur C. Clarke, (London: Michael Beazley Publishers Ltd 1977). Moore writes

Perhaps we may look back to the words of Percival Lowell, written in 1906. He may have been wrong in his interpretation of the so-called Martian canals, but at least he put forward an idealistic view of the attitude of his ‘Martians’. Whom, he believed, had outlawed warfare and had united in order to make the best of their arid world. There could be no conflict upon Mars. In Lowell’s words: ‘War is a survival among us from savage times, and affects now chiefly the boyish and unthinking element of the nation. The wisest realize that there are better ways of practicing heroism and other and more certain ends of ensuring the survival of the fittest. It is something people outgrow.’ Let us hope that we, too, have outgrown it before we set up the first base upon the red deserts of Mars. (p. 18).

The passage is shocking in its espousal of Social Darwinism, and the ‘survival of the fittest’. Moore himself had extreme right-wing, anti-immigrant views. But he was also firmly anti-War, no doubt strongly inspired by the death of his girlfriend during an air raid in World War II.

And would that humanity had outlawed war! We too also need, if not global government, at least global far-reaching global co-operation to fight the environmental decline of our own planet through climate change and mass extinction. Hardly a day goes by without another report in the papers about the immense seriousness of the environmental catastrophe. This last week two documentaries in particular on British TV warned us further about its extent. One was Drowning in Plastic, presented by Liz Bonnin, and the other was the final edition of Andrew Marr’s Darwin’s Dangerous Idea on BBC. This last programme appeared to trace the origin of the science of ecology to Darwin, and claimed that humanity’s destruction of the world’s ecosystem was partly due to ignorance of this aspect of Darwin’s theory of evolution.

It’s a contentious claim, as I suspect that the awareness of the interconnectness of living creatures actually predates Darwin, and that other scientists and naturalists, like the German explorer Humboldt, also made their own important contributions to development of ecological awareness.

But regardless of Marr’s claim about Darwin, we do need to be more like Lowell’s Martians to develop the global political, economic and social systems we need to fight our species’ destruction of the environment and its myriads of living creatures. And sadly, this is still being fought by vested corporate interests, such as the oil industry in America, led by the Koch Brothers, and right-wing Conservative parties. Such as the Republicans and Donald Trump, as well as the Tories and Tweezer over this side of the Atlantic. Lowell’s Martians don’t exist, but Lowell idealistic vision of them still has lessons for us in our own world, beset by environmental degradation and corporate, imperialist warfare.

Painting of Blake’s 7’s ‘Liberator’ by David A. Hardy

September 9, 2017

This is for all the fans of the classic British SF series, Blake’s 7. It’s a painting of their spaceship, the Liberator, before it came crashing to an end in ‘Tereminus’, the last programme of the third series. I found the painting on the SF/ weird art site, Tomorrow and Beyond.

David A. Hardy is one of the great veterans of British space and SF art. He’s illustrated numerous books on astronomy, including several with the late Sir Patrick Moore. The best known of these is probably The Challenge of the Stars. Hardy’s unusual in that he crosses the divide between space and SF art. It seems ridiculous to me that there is such a division, considering how so much science fiction art is set in the Black, and the care with which many SF artists take to portray it. I was rather surprised to find this. I knew Hardy also painted SF, I didn’t think he’d painted any TV material.

Torygraph Journo’s Book on Interstellar Travel Through Artificial Black Holes

August 10, 2017

The Iron Sun: Crossing the Universe through Black Holes, Adrian Berry (London: Jonathan Cape 1977).

No, not the Iron Sky, which was a Finnish Science Fiction film that came out a few years ago, in which the Nazis secretly colonized the Moon, and fight an interplanetary war with an America governed by a female president, who bears a certain similarity to Sarah Palin. This is the Iron Sun, a book in which Telegraph journalist Adrian Berry explains his theory that it should be possible to explore space using artificial Black Holes to travel faster than light. Berry was a Fellow of the Royal Astronomical Society, a Senior Member of the British Interplanetary Society, and a member of the National Space Institute of America. According to the potted biography on the back flap of the dust jacket, he also covered two of the Moon Landings from Cape Kennedy and Houston. Along with this book, he also wrote The Next Ten Thousand Years and The Great Leap.

The latter book was published in the 1990s, and is also about interstellar travel and exploration. It’s a good book, though marred by Berry’s Libertarian politics. Towards the end of the book, he devotes an entire chapter to argue for Von Hayek’s daft and destructive economic ideas. So did a number of other space and extreme technology groups at the time. The transhumanists, the crazy people, who want to transform themselves into cyborgs, explore the Galaxy, and ultimately achieve immortality by uploading themselves into computers, were also very much into Von Hayek and Libertarianism. I have a feeling that this has gone by the way now. A friend of mine, who was also into it, told me a year or so ago that the Austrian economist is rather passe now. One of the leaders of the movement has said that Hayekian economics was just something they were into at the time, and they’re now distancing themselves from him, so that his ideas aren’t synonymous with the movement as a whole.

In this book, after taking the reader through Einstein’s Theory of Relativity and explaining what Black Holes are, Berry then advances his book’s central idea. This is that humanity will be able to use a fleet of automated Buzzard ramjets as cosmic bulldozers to create an artificial Black Hole of a particular size one light year from Earth. The Buzzard ramjet was a type of spaceship devised in the 1970s. Instead of taking its fuel with it into space, like conventional rockets and spacecraft, the ramjet would scoop up the necessary hydrogen for its nuclear fusion engines from the surrounding interstellar medium, in the same way that a high-performance ram jet sucks in the air it needs to reach supersonic velocities from the Earth’s atmosphere. It was an immensely popular idea amongst space scientists, SF fans and advocates of the human colonization of space, as it appeared a practical way of creating a spacecraft that could reach the very high speeds approaching that of light needed to cross space to the nearest stars within a few years, or tens of years, rather than centuries and millennia.

Berry believed that strong electromagnetic fields could be used to collect and push the necessary hydrogen atom ahead of the spacecraft. Once in place, the hydrogen and other gaseous material would be forced together into a single mass, until it was so large that it collapsed under its own gravity, forming a Black Hole.

It was Carl Sagan, who first suggested the possibility of using Black Holes as cosmic subways to travel across the universe faster than the speed of light. Einstein, Rosen and other scientists hypothesized that the gravity inside Black Holes was so massive, that not only did it crush matter out of existence, but it also created a wormhole through space and time to, well, elsewhere. An object, including a spaceship, could enter a Black Hole to travel through the wormhole, to exit from a White Hole somewhere else in the universe, or even in a different universe altogether.

The Black Hole would be built a light year away, as this would be a safe but accessible distance. The construction ships would be automated as they would not be able to pull back once construction of the Black Hole was underway, and would be allowed to fall into it.

Berry admits there is one problem with his scheme: no-one knows how far away, nor in what direction, the resulting wormhole would extend. He therefore argues that the first astronauts to use the new wormhole would also have their own fleet of construction vessels, in order to build another Black Hole at their destination, which would create the White Hole needed for them to return to the Solar System. The process would take about forty years.

He explains the details of his proposal in a fictitious interview. There’s also an epilogue, and three appendices, in which he gives further information on Black Holes, including the navigable apertures created by Black Holes of varying sizes.

It says something for the optimism about the future of spaceflight in the 1970s that Berry considers that we should have the capability to do all this sometime around 2050. The 1970s were the decade when it seemed almost anything was possible after the Moon Landings, and astronomers and writers like Sir Patrick Moore seriously predicted that by now we’d have bases and colonies on the Moon and Mars, holidays in space, orbital habitats at the L5 points, as suggested by Gerald O’Neill, and would be gradually expanding into the rest of the Solar System.

If only that had happened!

Despite the formation of public groups, like the Mars Society and the Space Frontier Foundation, for the colonization of space, humans so far seem stuck in Low Earth Orbit. There have been plans over the past few years for crewed missions to return to the Moon, and to Mars, but these haven’t materialized. NASA is planning an expedition to the Red Planet in the 2030s, but I’m really not confident about that every happening. And if it’s a struggle for us to get to Mars, sixty or seventy years after the Moon Landings, it’s going to be impossible for us to build a Black Hole.

Part of the problem is the difficulty of building a viable Buzzard ramjet. After the idea was proposed, someone worked out that the interstellar medium was so rarified that the vehicle would need a ramscoop 3,000 miles long to collect all the gas it would need. I’m not sure if this makes it completely impossible – after all, firms like the Hanson Trust back in the 1980s tried selling themselves to the general public with commercials telling the world that they made enough plastic chairs to go round the Earth so many times. And it might be possible to develop superlight materials for the scoop so that it would not be impossibly heavy. Such a material would similar to the mylar suggested for the solar sails for the Starwisp mission. This is a suggested mission to send a 50 kilo instrument package to Alpha Centauri in a journey lasting thirty years or so. And the construction of a space elevator, which would have to be of a light material strong enough to take the weight of cable cars and carry them tens of thousands of mile into space out of the Earth’s gravity well seems to me to present even greater problems. But even if a ramscoop of that size isn’t impossible, it would be very, very difficult and extremely expensive.

Not all scientists are convinced that it should be possible to use wormholes in this manner anyway. Philip’s Astronomy Encyclopedia state that one particular type of Black Hole, rotating Kerr Black Holes, which don’t have the singularity that eventually destroys all the matter passing through it, ‘have fascinating implications for hypothetical space travel to other universes’. (‘Black Holes, p. 57). However, the entry for ‘Wormholes’ states that, although they’re predicted by Einstein, ‘such wormholes cannot exist in reality, since the occurrence of white holes is forbidden by the second law of thermodynamics.’ (p. 440). On the other hand, Russian physicists have shown that it’s possible to create a wormhole a few light years in extent, though this would take more energy than is currently available in the universe.

I hope that it may one day be possible to construct such wormhole subway routes through the cosmos, as suggested by Sagan. I also wonder if the book may also have influenced comic writer Pat Mills in the creation of the Black Hole and White Hole bypasses for Termight – Earth thousands of years in the future – in the Nemesis the Warlock Strip in 2000 AD. This was an artificial Black Hole and its White Hole counterpart, constructed by Earth’s engineers to provide instantaneous access to space. ‘Nemesis the Warlock’ appeared about 1979, and while it’s definitely Science Fantasy, Mills actually did some reading in science as research for the comic. He said in an interview nearly four decades ago that he shocked the comic’s management because he bought a whole stack of books on science and then invoiced the comic company for them as research. He was annoyed that the attitude to comics at the time was so low, that the idea of doing basic research for them was looked upon with horror. Ah, how things changed after Frank Bellamy and ‘Dan Dare’. Bellamy’s studio for Britain’s greatest space hero, with the exception of Judge Dredd, included a model maker and researchers. Unfortunately, this was all cut away as an unnecessary expense when the Eagle changed hands. Sales had fallen, and the comic was then making a loss. Hence the decision to cut down the number of staff in the studio. But it does show the initial commitment to quality of strip’s creators, and Dare and Bellamy’s superb artwork are still admired as one of the greatest pieces of British comic art and literature.

The Fantastic Space Art of David A. Hardy

April 22, 2017

This is another couple of videos from the redoubtable Martin Kennedy showcasing the amazing work of yet another space and Science Fiction artist, David A. Hardy. Hardy is one of the longest running space and SF artist working. The entry on him in Stuart Holland’s Sci-Fi Art: A Graphic History, runs:

David Hardy’s introduction to astronomical illustration was a somewhat rushed affair. In 1954, as a mere 18-year-old, he was commissioned to produce eight black and white illustrations for a book by legendary UK astronomer Patrick Moore: Suns, Myths, and Men. He had just five days to create them before British national service-conscription-required him to join the Royal Air Force. The commission was all the more remarkable as Hardy had only painted his first piece of astronomical art four years previously, inspired by the work of Chesley Bonestell.

Since those early days, Hardy (1936-) has garnered numerous awards for artwork that spans the science fiction/hard science divide. Born in Bourneville, Birmingham, in the UK, he honed his talents painting chocolate boxes for Cadbury’s. By 1965 he had become a freelance illustrator, beginning a career that resulted in covers for dozens of books and magazines, both factual, such as New Scientist, Focus, and various astronomical publications, for which he also writes; and SF, including Analog and Fantasy & Science Fiction. 1972 saw the publication of Challenge of the Stars, which Hardy not only illustrated but co-wrote with Patrick Moore (the book was updated in 1978 as New Challenge of the Stars). A bestseller, it joined the select pantheon of book that influenced a new generation of up-and-coming astronomical artists.

By now, Hardy’s work was receiving international recognition, and in 1979 he was nominated for the Hugo Award for Best Professional Artist. Tow years later, another book followed, Galactic Tours, which as the name suggests is a “factitious” guidebook for the interstellar tourist. As a result of the book, travel company Thomas Cook approached Hardy about becoming a consultant on the future of tourism in space-long before Richard Branson had planned Virgin’s conquest of the stars.

Hardy has written an SF novel, Aurora: A Child of Two Worlds; worked on the movie The Neverending Story, and on TV (Cosmos, Horizon, The Sky at Night, Blake’s Seven), and produced record covers for – unsurprisingly – Holst’s The Planets and for bands such as Hawkwind, the Moody Blues, and Pink Floyd.

In 2004, Hardy’s long-standing partnership with Patrick Moore culminated in the award-winning Futures, in which the two explored the changing perceptions of space exploration since they first collaborated in the ’50s, the ’70s (the era of Challenge of the Stars) and into the 21st century. Artistically, Hardy has also embraced the growing digital trend that started in the approach to the new millennium. While still painting in acrylic and oil, he now uses Photoshop as a matter of course.

In March 2003, Hardy was paid perhaps the ultimate accolade an astronomical artist can receive: he had an asteroid [13329] named after him. Discovered ini September, 1998, it was christened Davidhardy=1998 SB32-high praise indeed!
(P. 130).

Several of the paintings in the video come from the Challenge of the Stars and its updated version.

The videos also include his cover illustration for Arthur C. Clarke’s The Snows of Olympus: A Garden on Mars – the History of Man’s Colonisation of Mars, which is another ‘future history’, this time of the terraforming of the Red Planet.

I have to say that I’m really impressed he also worked on Blake’s 7. This was low-budget British SF, but it had some create scripts and a really beautiful spaceship in The Liberator. And I would far rather go into space on something designed by Hardy, and operated by Thomas Cook, than by Branson.

David A. Hardy on Terraforming the Solar System

December 31, 2016

As well as colonising the other planets in the solar system with self-contained, sealed environments to protect their future human inhabitants, it may also one day be possible to terraform them. This means transforming them from their currently hostile conditions to an Earthlike environment. At the moment, the planet considered most suitable for terraforming is Mars, because of all the planets it seems to present the least obstacles to this form of planetary engineering. I can remember reading a piece in the Sunday Express way back in the 1980s, which discussed James Lovelock’s suggestions for creating an earthlike atmosphere on the Red Planet. Lovelock is the creator of the Gaia hypothesis, the theory that Earth’s biosphere acts like a gigantic, self-regulating organism. This became a favourite of several of the New Age neo-pagan religions in the 1990s, where it was incorporated into worship of the Earth Mother. Lovelock believed that while nuclear weapons were a serious danger to all life on Earth, they could be used creatively on Mars to produce an environment that would support life. Mars has large amounts of carbon dioxide locked up at its polar regions in the form of dry ice. he believed that this could be melted using nuclear missiles. Specially targeted nuclear explosions would cover the polar regions with an insulating layer of soil. This would keep the heat in, which is currently radiated back into space, reflected by the white ice. The rise in temperature would cause the dry ice to sublimate into carbon dioxide gas. This would then start a greenhouse effect, which would see more carbon dioxide and other gases released into the Martian atmosphere. This would eventually create an environment, where the atmosphere was thick enough for humans to be able to move around without space suits. They would, however, still need oxygen masks and tanks to be able to breathe. Lovelock was extremely optimistic about how many weapons would be needed. He believed that you’d only need four, if I remember correctly.

Lovelock’s ideas are wrong, but other scientists and Science Fiction writers have also suggested ways of transforming the Red Planet into a place where life can thrive. Back in the 1990s, Kim Stanley Robinson wrote a trilogy of books set on a Mars that was being colonised and terraformed by humanity, beginning with Red Mars. The veteran SF writer, Arthur C. Clarke, also produced a book in which he used to a computer programme to show what Mars may look like as it’s being terraformed. Over hundreds, perhaps even a thousand years, rivers, seas and oceans develop and green spreads over its land surface as vegetation begins growing on its previously barren surface.

David A. Hardy, the space artist, who has illustrated a number of books on space, including several with the late Patrick Moore, also described the various ways in which the Moon, as well as Mercury, Venus and Mars, could be terraformed in his 1981 book, Atlas of the Solar System (Kingswood, Surrey: World’s Work). He writes

Taking the concept of manned bases on other planets still further, there is the staggering possibility of ‘planetary engineering’ or terraforming – a term coined in 1942 by science fiction writer Jack Williamson. The idea is simply to make other worlds habitable by humans. An early suggestion, in 1961, by Carl Sagan was to ‘seed’ the atmosphere of Venus with blue-green algae, converting the carbon dioxide into oxygen and at the same time reducing the pressure and temperature (by eliminating the greenhouse effect). The upper clouds would condense and rain would fall, forming oceans.

A more recent alternative, now that we know how hostile Venus really is, is to ferry in ice asteroids 15 km or so in diameter, put them into orbit around Venus and aim them, using rocket jets, at a specific spot on the surface. Each crashes at nearly 100 km/s, at such an angle that Venus’ rotation is increased until a 24-hour day is approached, while at the same time water is provided as the ice melts. Then the atmosphere is seeded with blue-green algae.

The same could even be done with the Moon: once given a breathable atmosphere by baking oxygen out of the rocks with giant parabolic mirrors, it would remain for thousands of years, even if not replenished. The time factor for the operation is remarkably short. Mercury would need to be shielded from the Sun by a ‘parasol’ of rocky particles put up by mass-driver, or by a man-made ring. Mars would need to be warmed up, perhaps by reflecting sunlight on to the poles with huge, thin metal-foil mirrors, increasing the energy-flow at the poles by 20 per cent. or we could spread dark material from its carbonaceous moons on them with a mass-driver. Rich not only in carbon but in oxygen, nitrogen and hydrogen, this is excellent raw material for fertiliser. One the atmosphere was thickened, the greenhouse effect and carefully chosen plant life should do the rest. (pp. 86-7).

The process of transforming these planets into habitable worlds would take quite a long time – decades, if not centuries, and at present it is the stuff of science fiction. But I hope that there will be a time when we can move out from Earth to create new homes for life and civilisation on these worlds.
