The legacy of rotary machine design can be seen, in part, as an inhibition of linear motor experimentation, even as far as the 1970s. In rotary machines, the tangential direction was the thrust direction and the axial direction was simply a means of increasing power output. Three-dimensional thinking was, in some ways, more advanced in the Victorian era... the Second Age of Topology can be seen as having had its beginnings in the demand for high-speed propulsion, the problem of the long pole pitch and the resulting development of the TFM concept.

[A] world financial recession brought governments into conflict with technological innovation in linear motors in the mid 1970s. Looking back... it will seem amazing that at a time when millions of pounds worth of commercially manufactured linear motors had been sold and had proved their worth, everyone was so slow to appreciate their value in the transport scene, knowing that bigger, faster motors would have enormously superior characteristics to those used for sliding doors, traveling cranes, conveyor belt drives and the like.

Electric motors and generators 'came of age' over almost the same period that engineering was becoming clean and respectable as a profession. Although technology... preceded science, indeed paved the way... scientists were regarded for centuries as belonging to the upper class, the intelligentsia, so closely related to philosophers as to allow overlap. In such a world, technology was not recognised as a subject and engineers... did not appear until there were 'engines' for them to look after. ...Even in the early part of the twentieth century, science as a whole was almost a 'middle class' occupation compared with studies of the classics.

It is not strange that the engineer fails to produce a unique solution, that his product is seen to be the result of 'art' more than science. ...The product becomes a matter of opinion... and joins the ranks of many other products such as literature, painting and sculpture, and... clothing. It has, in fact, its own history of Fashion.

The universities and the factories were as far apart as the gymnasium and the monastery. ...[T]his watershed inhibited linear motor development for the industrialist would make a linear machine, basing his designs on conventional rotary machine practice, find it to have an efficiency of 20 per cent and a of 0.1, and abandon it for the rest of his career. The reason for the low values of these, in part still fashionable quantities, was not only the lack of theoretical ability but the low speed and small size of applications...

I'm like a child who's been brought up inside an institution and has never seen the outside world, the sea, or trees in a wood... Coming here was like being taken out of that box and put into the marvelous real world that there is, and I've simply been standing and gazing in wonder at all of the things that there are in the universe. And I'd just like to live to be 200, because one lifetime isn't enough. ...Of course I shall never retire, I mean when, I'm 65 I hope they'll make me Professor Emeritus, but I also hope that they'll let me go on working. ...I'm writing a book on engineering and biology and the last chapter is called "Gazing Wonder", and that's how I can sum it up.

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.

I make most of my inventions when I'm talking to other people. ...I drag them from their interest into mine, and then they thank me when they leave, and I feel as if I should pay them a fee, because I feel as if I've used their brain to sort of reflect from.

I was telephoned by a man called Alexander Charles Jones, who asked me if he might bring me a box of apparatus which he said when put on frictionless casters and set in motion inside, would displace itself outside its own dimension. Immediately I knew this man was different. ...Any ordinary crank would have said, "How would you like to see Newton's Laws disobeyed." ...So I said... "Does you box contain anything that might loosely be described as a gyroscope?" ...He said, "In the box, there is a gyroscope." I said, "I think you'd better come and show it to me... because I know enough about gyros to know that they're like electromagnetism, and I've studied electromagnetism for thirty years and I know darn well I don't understand it, and I don't understand gyros either, but I can invent new things in electromagnetism once a year. And if you've got something new about gyroscopes I want to see it." And he brought it, and it did. And that was the start of a new line of research for me. And then, about a year later, I met a second enthusiast called Edwin Rickman who added his own brand of instinct that... improved the ideas we'd already got. Let me say of Alex Jones that since I first met him that I've been convinced both of the validity of his argument, and been impressed with his feel for what I'd call the elements of nature. A thing that the more learned acknowledgement of science and mathematics have seldom had, a natural feel for what goes on...

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.

When you discover something or observe something for the first time, you... wonder how that works, and then you make one, and you look at it, and you decide you'd better find out how it works. ...[Y]ou set about a detailed series of experiments, and eventually, ...you have to do the sums, it wouldn't be respectable without doing the sums... [Y]ou do the sums and then you publish it as a paper in the learned society journal. ...[Y]ou write it as if it was done from the front, as if on morning one you said "I will now invent the magnetic river..." ...[T]his very unfortunate phrase keeps coming in, "Now it is cleat that..." and "Clearly, obviously..." None of it is obvious. It wasn't the day before you started. No, you do it from the back.

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.
