" "I have been told by different people on separate occasions that the first patent on linear motors was filed by the Mayor of Pittsburgh in 1890, and that it was an induction machine applied to loom shuttle propulsion. ...[T]here is certainly a patent with the same objective in 1895. ...[T]he name [flying] given to James Kay's shuttle of 1733 suggests movement without contact and, as with modern transport in which it is proposed to have ground vehicles 'hovering' clear of the ground, Tesla's invention promised immediate success if it could be applied in linear form. ...The... 70-80 years during which progress in linear motors was extremely slow clearly needs an explanation. ...[T]here are many contributing factors, not least that of the 'amateur' status of the textile inventors in the world of electrical engineers.

About Eric Laithwaite
Eric Roberts Laithwaite (14 June 1921 – 27 November 1997) was a British electrical engineer, known as the "Father of " for his development of the and maglev rail system. He and Fredrick Eastham designed a self-stable magnetic levitation system called (which incidentally appeared in the film The Spy Who Loved Me). Laithwaite derived an equation for "goodness", which parametrically described motor efficiency in general terms, and which he interpreted as implying that motor efficiency increases with size. He made many television appearances, including the to young people in 1966 and 1974. Laithwaite was also a keen amateur entomologist and the co-authored The Dictionary of Butterflies and Moths (1975).

The Jabberwock was a monster with many heads. As such it resembles... the manner in which we divide our science into Physics, Chemistry, Biology, etc., and then Physics into Heat, Light, Sound, Magnetism and Electricity. Often one can spot the various heads as being Laws of Physics, and some of them look into mirrors, see their reflections and think that the total number of their kind is bigger than it really is. Thus they attempt to co-exist with their own shadows and reflections. One of the best examples... is... Laws of Electromagnetic Induction.
Perhaps it was World War II which came to the rescue again when the ridiculous Professor became almost indistinguishable from the 'Back Room Boy'...It reminded me of a young lady who was quite accurately described as 'long and lanky' until she inherited half a million pounds and overnight became 'tall and stately'. The image of a Professor 'stumbling across ideas' was transformed into the Scientist making 'inspired guesses'. 'Men ahead of their time' became a common compliment to those whose ideas were so abstract that they could not be understood.

[T]he academic tended to dislike the industrialist and the industrialist both distrusted and feared the academic—distrusted because 'theory never works in practice' and feared because the managing director might reveal some chink in his 'armour of experience' when confronted by the academic in the presence of some of his own staff. Had not the 'long-haired Professor' long been a music-hall joke and his caricature the subject of comedy films?
