The Prussian Confessional Church’s Denunciation of Nazi Genocide

March 20, 2019

One of the scandals of the Nazi regime was that the churches, who should have led the opposition to Nazism, did far too little to resist. And quite often the resistance that was offered was simply to preserve their own freedom against the demands and attempts at coordination by the Nazi state. Nevertheless, there were many heroic Christian clergy and lay people, who did resist Nazism, like Dietrich Bonhoeffer, who declared Hitler the Anti-Christ. 400 Lutheran pastors paid for their opposition by being murdered in Buchenwald concentration camp. The Nazis also devised a special emblem to be worn by Christian opponents of Nazis – Bibelforscher, ‘Bible Students’, as they were dubbed. This was a purple triangle, like the pink triangle worn by gay men and the black triangle of the ‘asocial’ and ‘workshy’. Most of those interned were Jehovah’s Witnesses, who refused to accept Hitler as a ‘secular messiah’.

In June 1936 the Confessional Church – a Lutheran organisation that had split off from the official National Church – issued the Barmen Memorandum attacking not only Nazi anti-clericalism, but also Nazi ideology, racial anti-Semitism, the perverted judicial system and the concentration camps. Some of those who signed it, including the head of the Confessional Church Friedrich Weissler, were imprisoned and executed. Seven years later, in October 1943, the Prussian Confessional Synod at Breslau denounced the Nazi extermination policy as unchristian. They declared

Concepts such as “rooting out”, “liquidation” and “unworthy life” are not known to the Divine order. The extermination of people solely because they are related to a criminal, or old or mentally disturbed or belong to an alien race is not a sword to be wielded by the state.’ This included ‘the life of the people of Israel’. Moreover, claiming that you were merely acting on orders was no defence: ‘We cannot permit superiors to relieve us of our responsibility before God.’

See: Karl Dietrich Bracher, The German Dictatorship (Harmondsworth: Penguin 197) 477.

D.G. Williamson, The Third Reich (Harlow: Longman 1982) 76.

James Taylor and Warren Shaw, A Dictionary of the Third Reich (London: Grafton Books 1987) 88.

I’m putting this up because the extreme Right in America and Europe is trying to justify its demands for the persecution of Muslims and their forcible removal or mass murder as the necessary defence of Europe’s Judaeo-Christian and secular, enlightenment heritage. The Nazis despise the Enlightenment and its doctrines of tolerance, humanity and the brotherhood of nations, which should serve as a warning to anyone who believes they can adopt their policies to defend it. And while many Nazis were Christians, and were supported by anti-Semites within the churches and wider German and European society, others like Alfred Rosenberg, the Nazis official ideologue, and Heinrich Himmler, the head of the SS, were fervently anti-Christian. Hitler himself was a pantheist. He had been raised a Catholic, but had very much turned against his upbringing. In his Table Talk he freely describes how unimpressed he was with his RE teacher at school, how since he was 12 years old he wanted to blow the Catholic mass up with dynamite, and how the Reich should found astronomical observatories all over Germany as part of a campaign to destroy Christianity. And one of the reasons the mainstream churches are uniting with Muslims to denounce the massacre in New Zealand is because of memories of the Third Reich, and the churches’ collaboration with the Nazis, as well as other atrocities committed through history in the name of religion.

The Barmen Memorandum and the 1943 condemnation of Nazism by the Breslau Confessional Church not just condemn Nazism, but also anyone else who seeks to exterminate other innocent people simply because they are of a different race or ethnicity. And that includes modern Western racial terrorists of the Nazi, Alt Right, or racial populist fringe, such as New Zealand murderer.

‘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.

Radio Programmes Next Week on Homelessness, Conspiracy Theories and Aliens

February 6, 2019

Looking through next week’s Radio Times for 9th-15th February 2019 I found a number of programmes which might be of interest to some people following this blog.

On Monday, 11th February at 8.00 pm on Radio 4 there’s Beyond Tara and George, about rough sleepers. The blurb for this programme reads

Last year there were nearly 600 deaths on the streets of the UK. In this follow-up to last summer’s Radio 4 series on east London rough sleepers Tara and George, presenter Audrey Gilan catches up with the pair to ask what it would take to prevent the unnecessary deaths of homeless people. (p. 137).

Then a half hour later at 8.30 on the same channel, Analysis covers conspiracy theories. The Radio Times says of this

Professor James Tilley explores the current spate of political conspiracy theories, and examines what belief in them tells us about voters and politicians.

The next day, Tuesday 12th February, at 1.30 pm on the Beeb’s World Service there’s Documentary: So Where Are the Aliens?, which the Radio Times describes thus

Space, to quote the late, great Douglas Adams, is mindboggling big. So huge, in fact, that the probability of there being civilized life elsewhere in the universe is almost a mathematical certainty. This begs an obvious question, to which Seth Shostak – chief astronomer of the Seti institute (Search for Extraterrestrial Intelligence) has devoted his career. He speaks with fellow scientists Frank Drake and Jill Tarter about their pioneering work chasing extraterrestrial radio signals as well as the new listening and light-based techniques designed to open up the sky like never before. Last year’s tantalizing fly-by of the mysterious cigar-shaped Oumuamua has revived interest in this topic, although in 2019 ET could be forgiven for giving Earth a wide berth. (p. 138).

Regarding the programme on preventing the homeless dying, one way to stop it would be to fix the welfare state so that poor and vulnerable people didn’t become homeless in the first place. Giving more funding and expanding the number of homeless shelters so that they were safe and able to provide accommodation for rough sleepers would also be very good. As would support schemes for those with drug, alcohol or mental health problems. And as Mike’s pointed out in his reports on attacks on the homeless, it would also be very good idea for the right-wing media to stop portraying the homeless, as well as the disabled, the unemployed and those on benefits generally all as scroungers committing welfare fraud and generally demonizing them. But as the Tory party, the Scum, Express and Fail all depend on this for votes and sales, it isn’t going to happen.

The prgramme on conspiracy theories could be interesting, but I doubt it will actually face up to the fact that some conspiracies are real. Not the malign and bogus myths about a Jewish plot to destroy the White race, or that the business and political elite are really evil Reptoid aliens, a la David Icke, or have made a demonic pact with grey aliens from Zeti Reticuli to allow them to abduct us for experimentation while giving them the benefits of alien technology. Or similar myths about the Illuminati, Freemasons or Satanists.

The real conspiracies that exist are about the manipulation of politics by the world’s secret services, and secret big business think tanks and right-wing pressure groups. Such as the various front organisations set up by the CIA during the Cold War, the smears concocted by MI5 during the 1970s presenting Harold Wilson as a KGB agent, and the contemporary smears by the Integrity Initiative, funded by the Tory government, claiming that Corbyn and other left-wing figures across Europe and America were agents of Putin. And, of course, the real conspiracy by Shai Masot at the Israeli embassy to have Tory cabinet ministers, who didn’t support Israel, removed from government. As well as the embassy’s role in making fake accusations of anti-Semitism against entirely decent people in the Labour party.

But I’ve no doubt that the Beeb will shy well away from these real conspiracies, not least because of Britain’s sordid role in the West’s history of regime change in Developing nations that dared to defy the Americans and ourselves. The Beeb has put on similar programmes before, and the person being interviewed or presenting the argument was former Independent journo David Aaronovitch. And his line has always been to ignore these real conspiracies, and concentrate on all the mythical rubbish, which he presents as typical of the conspiracy milieu as a whole. Which you’d expect from an establishment broadcaster, that now seems to see itself very much as the propaganda arm of the Conservative British state.

Moving on to the programme on SETI, Shostak, Tarter and Drake are veterans not only of the search for intelligent alien life, but also of programmes and documentaries on the search. Drake was the creator of the now famous equation which bears his name, which is supposed to tell you how many alien civilisations we can expect to exist in the galaxy. He was one of the brains behind Project Ozma, alias ‘Project Little Green Men’ in the 1960s to listen for alien signals from two nearby, roughly sun-like stars, Tau Ceti and Epsilon Eridani. Which found zilch, unfortunately. Shostak and Tarter were two of the leaders of the new wave of SETI researchers in the 1990s, and Shostak wrote a book about the possibility of alien life and what they would possibly be like. This concluded that they wouldn’t be anything like us, ruling out aliens like Mr Spock in Star Trek. In size they would probably be the same as Labradors.

It’s been known now that the Galaxy is old enough and big enough, with the right kind of stars and an increasing multitude of known planets, some of them possibly suitable for life, for alien civilisations to have emerged several times. And if they only advanced at the speed of light, they should be here by now. But they’re not. So far we’ve detected no sign of them. Or no absolutely indisputable signs. So where are they? This problem is called the Fermi paradox after the Italian-American physicist, Enrico Fermi. Suggested answers are that life, or perhaps just intelligent life, is extremely rare in the universe. Space travel may be extremely difficult. Aliens may exist, but they may be completely uninterested in talking to us. In this respect, we may even be a ‘protected species’ considered too fragile at our current level of civilization for contact with the rest of the Galaxy. Or perhaps there really are predatory alien intelligences and civilisations out there, who automatically attack any culture naïve and trusting enough to announce their presence. In which case, all the alien civilisations out there are paranoid and keeping their heads well down. One of SF writer even wrote a collection of short stories, each of which gave one solution to the Paradox.

Jon Pertwee ‘Dr. Who’ Strip on the Bronze Age of Blogs

December 1, 2018

The Bronze Age of Blogs is a website dedicated to comics of the 1970s, though sometimes this is stretched to include strips from the late ’60s and ’80s. One of the strips it’s covered recently is a ‘Dr. Who’ strip from the comic Countdown/TV Action, which apparently ran from 1971 to 1973. The strip features the 3rd Doctor, as played by Jon Pertwee, and was written and drawn by Barry Haylock. According to the Pete Doree, the site’s author, the comic carried work by a number of great British comics artists, like Frank Bellamy, one of the artists on The Eagle’s Dan Dare, and Ron Embleton, whose name I recognize from 2000 AD.

I can vaguely remember TV 21 from my early childhood, including the Dr. Who strip. I can remember reading one such story, about an alien influence beaming in through a radio telescope and the TARDIS dematerializing just before we had a Hallowe’en party.

The Bronze Age of Blogs reproduces stories from the comics discussed, and so this post duly has one of the Doctor’s from the comic. To enlarge the images so that you can see them more clearly, and read the speech bubbles, simply click on them.

Two of the Candidates for the Fifty Pound Note: Alan Turing and Thatcher

November 27, 2018

Mike today put up a piece about the two candidates the government is considering sticking on the back of the fifty pound note. They are Alan Turing, the wartime mathematical genius, who broke the enigma code and helped shorten the war. One of the machines Turing designed, or helped design to break the code was programmable, and Turing is respected as one of the founders of modern computing.

He was, however, gay at a time when it was very much against the law. He was convicted of gross indecency, and chemically castrated, which led to him taking his own life.

Thatcher, on the other hand, is the woman whose policies have inflicted nothing but misery on this planet for nearly forty years. She started the Tories’ and New Labour’s privatization programme, including that of the NHS, the destruction of the welfare state and deliberately made signing on for unemployment benefit as humiliating as possible, in order to deter the poor from doing so. She was also determined to break the unions, manufacturing a strike by the NUM through the gutting of British coalmining, purely to break the union that had brought down Heath’s government years before. And she used the police has her army to attack and beat the miners, aided by a complicit media, including the Beeb. These ran the footage of the strike at Orgreave colliery backwards to make it appear that the miners were attacking the police, while it was the other way round.

Exactly as the great peeps on Twitter, whose comments Mike quotes in his piece about it.

Ah, but Thatcher was a chemist! She worked for Walls, inventing the process that injects air into ice cream to make it appear that there’s more of it than there is.

Well, if the government wants to put scientists, and especially women scientists, on the fifty pound note, I’ve got a few suggestions of my own. Female scientists they could choose include:

Dorothy Hodgkin. She’s the woman who should have got the prize for discovering the structure of DNA, as Crick and Watson were looking completely in the wrong direction until they walked past the door of her lab, and heard her talking about her work. She lost the Nobel to them, but did get another prize for another great discovery she made. If she hasn’t been already, it’s the right time to have her commemorated on our folding stuff.

Jocelyn Bell Purnell. She was the astronomer, who discovered pulsars. These are tiny, dense stars at the end of their lives, which send out a radio signal. They spin very quickly, so that the signal sweeps across the sky, so that they appear as a regular beat. At first it was believed that they might be signals from an extraterrestrial civilization. Some astronomers also believe that, while they’re natural, space-traveling aliens could use them as lighthouses to navigate their way across the Galaxy.

Helen Sharman. She’s another chemist, though at Mars, rather than Walls. But she is know for being the first Brit into space when she joined the British-Russian space mission to Mir in the 1980s. Since then, she’s been something of a science educator, appearing at events to encourage children to take up science.

Caroline Herschel. She’s the brother of John Herschel, and daughter of William. She and her brother were astronomers in 18th century Bath, making telescopes and discovering new stars.

I’m sure there are many others. These are all astronomy and space related, because that’s the area I’m interested in and know most about. All of these ladies have a better claim to be on the Fifty pound note than Thatcher.

But if you want another bloke, how about Dr. Jacob Bronowski. He was another mathematician working during the War. He was also the presenter of the 1970s Beeb science blockbuster, The Ascent of Man. He was also a Fabian socialist with a hatred of war. In The Ascent of Man he makes his view of armed conflict very clear by saying: ‘War is theft by other means’. It’s parody of Clausewitz’s famous phrase ‘War is politics by other means’. Bronowski’s description of war is very true, especially now when we’ve seen that the humanitarian interventions in the Middle East have all been about conquering them in order to despoil their oil reserves, loot their state industries and stop any kind of Arab and Islamic support for Israel. And Iran appears to be next on the hit list.

However, I do like the suggestion of Raab C. Brexit that it should be the sage of Govan, Rab C. Nesbitt on the notes. Having his mug staring out at them might just put a few of the really filthy rich off when they get it out to pay for their bottle of Krug.

Remember, it was Nesbitt who predicted that there’d be a war between the Toffs and the Scum. The Toffs would win initially, because they’ve got the army. But the Scum would be the victors, because they have all the Rottweilers.

Jai Singh’s Observatory in India: A Great Location for Dr. Who

November 18, 2018

Maharaja Jai Singh’s observatory in Jaipur, as photographed by the Archaeological Survey of India

Last week on Dr. Who, the Doctor and her friends traveled back seventy years to the partition of India to uncover the secret of Yas’ grandmother’s marriage. Yas is surprised to find that the man her gran, a Muslim married, was a Hindu. And as nationalism and ethnic tensions surged on both sides, her groom was murdered by his own brother as a traitor. Yas’ gran survived, and held on to the watch her husband of only a few hours had given her as a treasured token of their doomed love.

It was a story of family history, doomed romance set against the bloodshed of the Partition, which resulted in 4 million Hindus, Muslims and Sikhs being slaughtered in bloody massacres. And its central theme was the inevitability of history, as Yas could do nothing to save her gran’s first husband. It was similar in this respect to the Classic Star Trek episode, ‘The City on the Edge of Forever’. Written by Harlan Ellison, this had Spock, Kirk and McCoy travel back to Depression-era America. There Kirk falls in love with a woman running a soup kitchen. But she’s an opponent of America entering the war in Europe, who dies in car accident. If she lives, America will not enter World War II, and humanity will never go to the stars. Kirk is thus faced with the terrible necessity of letting the woman he loves die in order to preserve history.

It’s a good story, though I would have preferred one with a bit more science in it. The two aliens that appear, who the Doctor first believes are assassins and responsible for the murder of the Hindu holy man, who was to marry the happy couple, turn out instead to have reformed. Returning to find their homeworld had been destroyed, the two now travel through the universe to witness the deaths of those who pass unnoticed. They reminded me of the Soul Hunters in Babylon 5, an alien race, who travel through the universe to extract and preserve the souls of the dying at the moment of death. They are interested in ‘dreamers, poets, thinkers, blessed lunatics’, creative visionaries whose genius they want to preserve against dissolution.

Dr. Who has a tradition of the Doctor going back in time to meet important figures of the past. One such influential figure in India was Maharaja Jai Singh of Jaipur, who constructed great observatories in Jaipur and Delhi. As you can see from the piccy at the top, the measuring instruments used in astronomy at the time were built out of stone there. To my eyes, the observatories thus have the shape of the weird, alien architecture portrayed by SF artists like Chris Foss, as if they were monuments left by some strange future extraterrestrial civilization.

B.V. Subbarayappa, in his ‘Indian Astronomy: an historical perspective’, in S.K. Biswas, D.C.V. Mallik and C.V. Viveshwara, eds., Cosmic Perspectives: Essays dedicated to the memory of M.K.V. Bappu pp.41-50, writes of the Maharaja

In this respect, special mention needs to be made of Majaraja Sawai Jai Sing II (1688-1743) of Jaipur, who was not only an able king but also a skilled astronomer and patron of learning. He built five observatories in different locations in Northern India. The observatories now standing majestic and serene in Jaipur and Delhi bear testimony to his abiding interest in astronomy and to his efforts for augmenting the astronomical tradition with an open-mindedness. The observatory at Jaipur has a large number of instruments – huge sun-dials, hemispherical dial, meridian circle, a graduated meridianal arc, sextants, zodiacal complex, a circular protractor (which are masonry instruments), as well as huge astrolabes. Sawai Jai Singh II meticulously studied the Hindu, Arabic and the European systems of astronomy. He was well aware of Ptolemy’s Almagest (in its Arabic version), as also the works of Central Asian astronomers – Nasir al-Din at-Tusi, Al-Gurgani, Jamshid Kashi and, more importantly, of Ulugh Bek – the builder of the Samarqand observatory. In fact, it was the Samarqand school of astronomy that appears to have been a great source of inspiration to Jai Singh in his astronomical endeavours.

No less was his interest in European astronomy. In his court was a French Jesuit missionary who was an able astronomer and whom Jai Singh sent to Europe to procure for him some of the important contemporary European works on astronomy. He studied Flansteed’s Historia Coelestis Britannica, La Hire’s Tabula Astronomicae and other works. He was well aware ot he use of telescope in Europe and he spared no efforts in having small telescopes constructed in his own city. In the introduction to his manum opus, Zij Muhammad Shahi, which is preserved both in Persian and Sanskrit, he has recorded that telescopes were being constructed during his lifetime and that he did make use of a telescope for observing the sun-spots, the four moons of Jupiter, phases of Mercury and Venus, etc. However, in the absence of a critical evaluation of his treatise, it is rather difficult to opine whether Jai Singh was able to determine the planetary positions or movements with the help of a telescope and whether he recorded them. No positive evidence has yet been unearthed.

The principal court astronomer of Jai Singh II was Jagganatha who was not only well versed in Arabic and Persian but also a profound scholar of Hindu astronomy. He translated Ptolemy’s Almagest and Euclid’s Elements from their Arabic versions into Sanskrit. The Samrat Siddhanta, the Sanskrit title of the Almagest, is indeed a glorious example of the open-mindedness and generous scientific attitude of Indian astronomers. (pp. 36-8).

It would be brilliant if there was a Dr. Who story using this fascinating, historic location, but as it’s almost certainly a prized national monument, I doubt very much the Beeb would be allowed to film there. Still, perhaps something could be done using CGI and a lot of imagination.

Karl Wilhelm Nageli and Purposeful Mutation

November 11, 2018

I found this very interesting piece on the 19th century biologist, Karl Wilhelm Nageli, and August Weismann in Richard L. Gregory’s Mind In Science (London: Penguin 1981). The modern theory of evolution, NeoDarwinism, is essentially a mixture of Darwin’s theory of evolution by natural selection mixed with Mendelian genetics. Roughly speaking, it views evolution as proceeding through random mutations. These supply the variations in species on which natural selection works, weeding out those varieties that don’t help the species to survive. Those that do, or at least don’t stop it surviving, are preserved and retained. Thus the little alterations in the characteristics of different species are created, which gradually accumulate over millennia and millions of years to produce new species of creature.

Darwin, however, didn’t know about heredity, which was introduced into his evolutionary theory by Weismann. He had developed the germ plasm theory, which was the precursor to the modern theory of DNA, famously discovered by Crick and Watson. Darwin also didn’t know about mutations either. He believed that heredity was a blending of the characteristics of the parents. I’ve got a feeling this was one of the arguments his opponents may have used against his theory, and that Darwin probably recognized the weakness of his theory there. At the time Darwin proposed his theory of evolution, I don’t think he was properly able to account for the emergence of novel characteristics in living creatures, on which natural selection acted.

It was Karl Wilhelm Nageli, who did this by introducing mutations into evolutionary theory, while rejecting Darwin’s idea of Natural Selection. Unlike evolutionary biologists after him, however, Nageli believed that these mutations had a purpose. It was the Dutch biologist Hugo de Vries, who introduced Mendelian genetics and the variation of characteristics into Darwinian evolutionary theory. Gregory explains it thus:

Neo-Darwinism adds to Darwinian Natural Selection a theory of heredity, which is itself derived from the, at the time (and perhaps still), controversial writings of the German biologist August Weismann (1834-1914). His papers (1868-76), translated into English as Studies in the Theory of Descent, (1882) proposed properties of a germ plasm which are similar to the fundamental doctrine of molecular biology, that information can only genetically pass from coded DNA to messenger RNA, and not the other way round. This genetic ‘diode’ rejects Lamarckian inheritance of individually acquired knowledge, or adaptive behavior. But we jump ahead, for Darwin had no knowledge of genes or mutations of genes.

The concept of evolution by mutational jumps is due to a Swiss botanist, Karl Wilhelm Nageli (1817). Nageli however rejected Darwin’s theory, for he supposed that there is a purpose in the direction of the jumps. He is heavily criticized for failing to appreciate the significance of Mendel’s work. He was shown the manuscript of Mendel’s paper describing his experiments on the breeding of giant and dwarf peas; his lack of interest is supposed to have prevented the work becoming known so that genetics was held up by some fifty years. Nageli’s concept of mutational jumps, but without built-in directional purpose, was developed by De Vries early in the present century.

Gregor Johan Mendel (1822-84) was an Augustinian monk. At the Abbey of St Thomas in Brunn, [Brno] he carried out his plant-breeding experiments, which depended on counting the proportions of tall and dwarf peas obtained by self-pollination. He found that the varieties did not converge to a medium-height pea plant, but that the tall and dwarf characteristics were maintained, and potentially present, in each variety. This was immensely important for Darwin’s theory, but unfortunately Darwin never came to hear of it.

The mutation theory was developed by the Dutch botanist Hugo De Vreis (1848-1935) who approached Mendel’s discovery by seeing that something like it was needed to give the variataion necessary for Natural Selection. He proposed that different characteristics might vary independently, and recombine in different ways. So was born the atomic-characteristic theory of inheritance, which later was embodied in gene and chromosome code structures – from which in turn developed modern molecular biology with the discovery by Francis Crick (b. 1916) and James Watson (b. 1928) of the structure of the long helical molecules of deoxyribonucleic acid (DNA). This, by replication, gives the physical basis of inheritance. Random change of the DNA structure give the variation necessary for Natural Selection. The drama of this discovery is superbly presented by Watson in The Double Helix (1968). (pp. 170-1).

Back in the 1980s, the astronomers Fred Hoyle and Chandra Wickramasinghe attacked Darwinian evolutionary theory in their book, Evolution from Space. In their previous book, Life Cloud, they had argued that life on Earth was seeded on Earth from space. While it’s an unorthodox theory, many scientists do believe that such panspermia, as it’s called, is a possibility. And the amino acids which form the basic building blocks of organic life has been found in meteorites, on Saturn’s moon, Titan, and in the nebulae, the clouds of dust and gas in space. What is far more controversial, and has been rejected by nearly all scientists, is their theory in Evolution from Space that the chance of organic life arising on Earth, and developing through Darwinian evolution, is so minute that evolution has to be directed by alien civilisations seeding space with the necessary genetic material.

In one passage in Evolution from Space, Hoyle and Wickramasinghe take the incidence of mutations in every generation, only a minority of which could be beneficial, and the combined length of time from the split, early in our evolutionary history, between the hominid lineage and the common ancestor of chimpanzees and gorillas 9 million years to argue that even this amount of time is insufficient to produce modern Homo Sapiens Sapiens, modern humanity. I’ve no doubt that this was immensely controversial and has been widely criticized and dismissed. It’s been taken up again more recently by the Intelligent Design people. And it wasn’t the weirdest of Hoyle’s and Wickramasinghe’s ideas. I think they also believed that the civilisations seeding this genetic material were computers in parallel universes. But if they are right after all, and random mutation can’t account for the development of the vast variety of living creatures we see around us, then it may be that it proceeds through purposeful mutations after all.

Going back to Nageli, even if his own theory of evolution has been discarded except for the idea of mutational jumps, I would far, far rather believe that evolution and the mutations necessary for it were shaped and guided by a loving creator, than are simply the result of blind chance as describes by Richard Dawkins in his book, The Blind Watchmaker.

Benjamin Banneker, America’s First Black Mathematician

October 26, 2018

October is Black History Month, and there’s a concern to find and publicise the scientific achievements of Black people. Leafing through David Wells’ The Penguin Book of Curious and Interesting Mathematics (London: Penguin 1997), I found this chapter about the pioneering Black American mathematician, Benjamin Banneker. I should warn readers that the quotation seems to come from a rather dated text, and uses the term ‘Negro’, which many Black people don’t like. However, don’t let it put you off the passage, which is well worth reading and clearly comes from someone profoundly impressed by Banneker’s achievements.

‘There is much to admire in the life of Benjamin Banneker (1731-1806). He was the first American Negro mathematician; he published a very meritorious almanac from 1792 to 1806, making his own astronomical calculations; using a borrowed watch as a model, he constructed entirely from hard wood a clock that served as a reliable timepiece for over twenty years; he won the enthusiastic praise of Thomas Jefferson, who was then the Secretary of State; he served as a surveyor on the Commission appointed to determine the boundaries of the District of Columbia; he was known far and wide for his ability in solving difficult arithmetical problems and mathematical puzzles quickly and accurately. These achievements are all the more remarkable in that he had almost no formal schooling and was therefore largely self-taught, studying his mathematics and astronomy from borrowed books while he worked for a living as a farmer.

‘But laudable as all the accomplishments of Benjamin Banneker mentioned above are, there is a further item that perhaps draws stronger applause. In his almanac of 1793, he included a proposal for the establishment of the office of Secretary of Peace in the President’s Cabinet, and laid out an idealistic pacifist plan to insure national peace. Every country in the world has the equivalent of a Secretary of War. Had Benjamin Banneker’s proposal been sufficiently heeded, the United States of America might have been the first country to have a Secretary of Peace! The possibility of realizing this honour still exists – and the time for it is overripe.’ (p. 97).

He must have been an amazing man, not just intelligent, but also highly determined to educated himself and rise so far in American society at a time when Blacks were enslaved and heavily discriminated against, even as free people. And he clearly puts the lie to the belief that Blacks are automatically thicker than everyone else, although the racists now are careful not to state this quite so explicitly.

Last Sunday, the Doctor and her friends traveled back to ’50s America to meet Rosa Parks. Parks was the lady of colour, whose refusal to stand for a White passenger started the bus boycott that became one of the major starting points of the Civil Rights movement. And on the way, they also met Dr. Martin Luther King, who was then a pastor at her local church. It was good, inspiring stuff, co-written by prize-winning children’s writer, Malorie Blackman. Who is herself Black.

The Doctor, as he/she flies back and forth across time, regularly meets the great figures of the past, like Shakespeare, Richard the Lionheart and so on. In a David Tennant story, the Doctor travels back in time to Pompeii, just before it erupts. This is caused by the presence of aliens, made of stone, deep within the volcano. Bending the laws of time, he saves one Roman who would otherwise have been destined to perish. This is a young man, who wants to grow up to be a philosopher. The Doctor rescues him, and encourages him to pursue his dream of studying the deep nature of reality. If the Beeb ever decides they want to try a similar storyline in which the Doctor meets a Black scientist or mathematician of the past, looking at this they should choose Banneker.

And we definitely, definitely need his plan for a Secretary of State. The various departments and ministries of war have no been renamed ‘Defence’ following World War II, at least in the West. But the world’s countries are just as belligerent, and the wars now being fought by the West in the Middle East are still for reasons of economic imperialism, however much they’re being sold to the public as humanitarian interventions.

And it’s all the more pressing now that we have governments in America and Britain determined to sell arms to the bloodiest of dictators and despots. Trump is withdrawing from an anti-nuclear treaty with Russia and gearing up for an invasion of Iran.

We’ve had a Black president in the shape of Barack Obama, but Banneker’s dream is still to be realized. Perhaps if more people became aware of him and his achievements, more people would come to support a Secretary of Peace. And perhaps ending wars before they could even begin.

JBIS Article on the Skylon British Spaceplane

October 9, 2018

In my last article, I discussed the forthcoming edition of the Beeb’s long-running space and astronomy programme, the Sky at Night, on the history of Britain in space. The programme will be presented by Tim Peake, and the blurb about it this week’s Radio Times looks forward to the opening of Britain’s first spaceport in Scotland within the next few years. The Radio Times doesn’t mention it, but recent newspaper articles have stated that such a spaceport will be built sometime in the very near future for launching the Skylon spaceplane. This is an unmanned vehicle, which has been developed as the successor to the 1980s HOTOL spaceplane.

Two of the scientists and engineers involved in the project, Richard Varvill and Alan Bond, published an article describing the plane in the Journal of the British Interplanetary Society, Vol. 57, no. 1/ 2, for January/February 2004. The JBIS is the technical magazine of the British Interplanetary Society, founded in the 1930s to encourage British research into rocketry and space travel. The article runs from p.22 to p.32. The article itself is too long to reproduce, but its abstract runs as follows:

SKYLON is a single stage to orbit (SSTO) winged spaceplane designed to give routine low cost access to space. At a gross takeoff weight of 275 tonnes of which 2202 tonnes is propellant the vehicle is capable of placing 12 tonnes into an equatorial low Earth orbit. The vehicle configuration consists of a slender fuselage containing the propellant tankage and payload bay with delta wings located midway along the fuselage carrying the SABRE engines in axisymmetric nacelles on the wingtips. The vehicle takes off and lands horizontally on its own undercarriage. The fuselage is constructed as a multilayer structure consisting of aeroshell, insulation, structure and tankage. SKYLON employs extant or near term materials technology in order to minimize development cost and risk. The SABRE engines have a dual mode capability. In rocket mode the engine operates as a closed cycle liquid oxygen/liquid hydrogen high specific impulse rocket engine. In airbreathing mode (from takeoff to Mach 5) the liquid oxygen flow is replaced by atmospheric air, increasing the installed specific impulse 3-6 fold. The airflow is drawn into the engine via a 2 shock axisymmetric intake and cooled to cryogenic temperatures prior to compression. The hydrogen fuel flow acts as a heat sink for the closed cycle helium loop before entering the main combustion chamber. (p. 22).

I’m delighted that the spaceplane is now set to enter service and look forward to the opening of the new spaceport in Scotland.

‘Sky At Night’ on Sunday on Britain in Space

October 9, 2018

Next Sunday’s edition of Sky at Night, for 14th October 2018, will be looking at the history of the British space programme and its possible future. The blurb for it in the Radio Times runs

Space Britannia

The future of Britain’s space programme, examining plans for the first UK spaceport in Scotland and the potential launch of revolutionary micro-satellites over the next decade. Guest presenter Tim Peake looks at the history of British space exploration.

The programme’s on BBC4 at 10.00 pm.

Britain did have a very successful space programme from the 1950s to about 1975. The UK developed a number of very successful sounding rockets, like Skua, which were used by meterologists for the exploration of the upper atmosphere. Development of the Blue Steel missile, intended as the launcher for Britain’s independent nuclear deterrent, resulted in the creation of the Black Knight rocket, which successfully launched a British satellite, Ariel, into orbit in 1975 from Woomera in Australia. And then the British launcher programme was cancelled, as civil service mandarins felt it would be more economical to have our satellites launched by the Americans.

We were also part of the ESRO programme in the 1960s until that finally fell to pieces in the 1970s. This was a European programme to produce a common launch rocket for European satellites We were to produce the first stage, and the French, Germans and Italians the others. Our part of the rocket worked perfectly, but there were problems with the other stages. This led to the programme’s cancellation as costs mounted. The French, however, continued developing rockets, leading eventually to the launch of Ariane, which has been immensely successful. We were left behind as the launch of our satellites depended on the Americans’ own plans and launch priorities. And the suspension of the space shuttle programme after the Challenger disaster, I believe, did result in Britain losing that as a launch vehicle for the duration.

Black Arrow, another British Rocket

There have been a number of plans to develop British spaceplanes, like MUSTARD in the 1960s and then HOTOL in the 1980s. HOTOL was cancelled because of difficulties getting the airbreathing engines to work. However, work on the plane continued after its official cancellation. The problems have been ironed out, and a new spaceplane developed, Skylon. It’s not a crewed vehicle, so it doesn’t look like any British astronauts will be going into space direct from Blighty just yet. Nevertheless, things are looking very optimistic for the British space programme, as there were reports in the papers a few months ago that the plane would be all set and ready to fly in the very near future, like 2020. I certainly hope so, and will look forward to seeing what this programme has to say about it all.
