Forget Marconi - here's Tesla


Found - this astonishing and admiring piece about Tesla from The Courier-Journal coming out of Louisville, Kentucky (Sunday, August 22, 1897)- although this was probably a syndicated article. It has some very good descriptions of the appearance and lifestyle of Tesla (His eyes are blue,deeply set, and they burn like balls of fire, those weird flashes of light he makes with his instrument seem also to shoot from them...) and manages to make light of Marconi's recent achievements as rather minor compared to Tesla (in May 1897, the 22 year old Marconi had sent the world's first ever wireless communication over open sea.)


....almost coincident with the announcement that (Tesla) has solved the great problem upon which he has been at work for nearly seven years comes the news that an Italian youth, Guglielmo Marconi has discovered a means of telegraphing without wires. The scientific world acknowledges the value of Marconi's invention. It admits its practical use. The same men who honor Marconi worship Tesla. Marconi has explained, and his methods are easily grasped. Tesla has simply said that he has accomplished his great work, and they believe. Years ago those recognised as masters admitted that Tesla had no peer in abstract electrical research. To-day the most scientific, the farthest advanced, look upon him with rapt admiring eyes. That which he says he has accomplished seems like the dream of an intoxicated god.

The Wheel of Orffyreus 2

The second and last part of a chapter from this fascinating forgotten work Oddities: A Book of Unexplained Facts (Allan, London 1928) by R.T. Gould. Gould was a polymath who appears to have tolerated fools and cranks gladly...however Johann Bessler was no fool (although he may have been insane) and no less a figure than the philosopher Leibniz and  and the scientist and Newtonian Willem Jacob 's Gravesande thought he had the secret of perpetual motion. Gould gets to the heart of the matter -as always with footnotes blazing...




Was Orffyreus honestly deceived when he wrote down such an incorrect description (for so we must regard it)† of his own mechanism? The thing is unlikely–but it is possible, as a later case has sufficiently shown.

 † The supposition that the wheel was kept going by external power does not, of course, exclude the possibility that it also contained "overbalancing" mechanism. If well made, this would waste very little power, though it could not generate any: and it would certainly impress an amateur mechanic like the Landgrave–the only man who ever saw it.

 Towards the end of the last War, public attention in the United States became focused, for a short time, upon an inventor bearing the perfectly incredible name of Giragossian. He appears to have been an honest but misguided man.

It is rocket science…

An apposite Jot in view of the recent death of Wurzel soundalike, Professor Colin Pillinger, the space scientist behind the Beagle 2 Mars landing vehicle.  The British Interplanetary Society was actually founded as long ago as 1934, when H. G. Wells was still alive, and is still going strong. I don’t know if Pillinger was a member, but in 1954 Arthur C. Clarke was on the publications committee and Patrick Moore was sitting on the Council. It is notable that although most of Moore’s fellow Council members had a degree, not one of them achieved anything like as much as this college dropout did in the field of astronomy.

The lead article in this January 1954 issue of the Society’s Journal  is a passionate plea by Dr A. V. Cleaver, head of the rocket division at Rolls Royce, for funds to be taken out of Europe’s various military budgets and put into a space programme which would ultimately see a man on the moon, flights to Mars and Venus, and ultimately the establishment of bases on these and other planets. Like many scientists before and since, Cleaver argues that the space race must be seen, not as a huge waste of resources, but as a logical extension of Man’s ceaseless striving to explore, and also a potential opportunity to develop various technological projects.

The writer betrays a political naiveté shared by many scientific visionaries, but his technical knowledge can hardly be faulted. The article ends with some fascinating appendices outlining time scales and costs. Interestingly, although he speculates  vaguely on significant progress occurring in  'generations' ,  he does make some bold predictions. For instance, by 1975 a 'relatively small piloted Earth –satellite- vehicle might take up its orbit'. And perhaps during the 1980s and 90s 'a few expeditions by small ships, carrying human crews of only one or two, might be organised.'

If anything, these predictions were a little conservative. Within just fifteen years of the article appearing, Man had landed on the Moon— in another issue of the Journal, the more cautious Clarke had predicted that this would happen by 1975. [RH]

Wonders of the 1930s

Some amazing covers from Modern Wonder: the Pictorial Review.(Odhams, London 1937 - 1940)







An astonishing magazine of modern invention, science and future prediction (visions of the future) subjects include: photography (miniature), aviation & flying boats, trains, shipping, wireless, television, military machinery, car racing, world record speed attempts, deep-sea diving & submarines, power stations and manufacturing. Striking, colourful covers, mostly by Bryan de Grineau and Lashwell Wood. Most issues have stories, (thrillers and science fiction) by such writers as Clifford Cameron, Stanton Hope, W. J. Passingham, Peter Barr, and in the first issue, John Wyndham (writing as John Beynon) Issue 1 also includes the required supplementary booklet 'Marvels of Today'. Issue 105 sees the appearance of Alex Raymond's 'Flash Gordon' comic strip, for about 30 issues, mostly in colour.  From issue 134, as Britain moves into the war, it's name changes to Modern Wonders (War Pictures).

How many molecules in a drop of whisky?

From R. Houwink's The Odd Book of Data (Elsevier, Amsterdam 1965) obtained from the amazing library of Jeremy Beadle MBE (1948 -2008) British entertainer, television star,  hoaxer, quizmaster, book collector and philanthropist (with his blind stamp reading 'Property of Beadlebum OK?')

It's a curious ur geek book full of data such as 'the light now reaching the star Pollux tells us about Hitler's rise to power, whilst a star in the Andromeda Nebula brings us, as it were, a visual greeting from the period when Homo Sapiens made his engravings in caves (15000BC)...' Here is a piece about the number of molecules in a drop of whisky:

Peter looked askance at John who was just polishing off his umpteenth glass of whisky.
'Steady on, old man… leave a drop for the stragglers!'
'Shteady on?'  echoed John, ' Why , theresh heapsh of the shtuff…hic.  Tell you what, shport, I'll dish out a thousand molecules per second to every living soul for the next 30 odd years…hic'.
John upturned his glass and shook a single drop on to Peter's palm. 'Take care of dishtribution old shport!'

Ignition!

John D. Clark. IGNITION! An informal history of liquid rocket propellants. Rutgers University, USA 1972.

This is rocket science. Cult book among rocket geeks or the aspiring 'rocketeer.' Includes amusing stories e.g. an attempt to use skunk oil as a fuel. Talk about stinks and bangs! 232 pages with illustrations. A very rare book much wanted by rocket enthusiasts and never reprinted... Clark is /was a great enthusiast in the line of Britain's sky man Patrick Moore. He has some useful cautionary tales e.g. he describes Red Fuming Nitric Acid (RFNA), a powerful oxidizer, as a substance that "attacks flesh with the avidity of a school of piranha." It can now be read online in a good version at Science Madness (3.5 MB)
Actual copies sometimes surface but tend to command several hundred dollars (sky high prices) but the pdf version is now very good.

World's most intelligent man

William James Sidis, born in Boston in 1898 to Russian émigré Boris, a psychologist and his wife Sarah, a physician, showed astonishing intellectual qualities from an exceptionally early age. By the age of one he had learned to spell in English. He taught himself to type in French and German at four and by the age of six had added Russian, Hebrew Turkish and Armenian to his repertoire. At five he devised a system which could enable him to name the day of the week on which any date in history fell. Hot-housed by his pushy father, Sidis entered Harvard at eleven, and was soon lecturing on 4 dimensional bodies to the University’s Maths Society. At twelve he suffered his first nervous breakdown, but recovered at his father’s sanatorium, and after returning to Harvard, graduated with first class honours in 1914, aged just sixteen. After a prepared talk at Harvard age 14 , when the audience applauded William turned from the podium and broke into hysterical giggles. Law School followed and by the age of twenty Sidis had become a professor of maths at Texas Rice Institute.

It was then that his troubles began . Looking back at his social gaucheness, hatred of crowds, physical awkwardness and obsessions, it seems very probable that Sidis suffered from Asperger’s Syndrome. But decades before the condition was recognised his eccentricities and aloofness were put down to arrogance. His good looks didn’t help him and he was teased by his female students, especially when he pronounced publicly that he would never marry and intended to live the rest of his life in seclusion.
