Top 15 Eric Laithwaite Quotes

I know no property of a gyroscope that conflicts... with the conservation of energy. ... is in the same state today that as it was in the fifteenth century when Leonardo da Vinci denounced it so properly. ...If you really want to see perpetual motion, look into the sky on a cloudless night and marvel at the size and movement within the Universe.

The whole idea of modern electrical machine theory... is based on this idea of the two independent axes, co-existing, co-related but nevertheless identifiably separate. We deal with complicated matters when we deal with rates of change of current, matters that require not only the Special Theory of Relativity, but the General Theory (the world of relative accelerations)... Might there not exist a similar complexity also in the , if rates of change of acceleration are involved? ...Work on rates of change of acceleration (American scientists have called it 'surge') is very sparse.

Circularity is a powerful concept, the idea of a closed loop even more so. In circular motion there is magic, just as there is in electro-magnetism. But it only manifests itself when it is, like (shall we say for the moment, rather than a 'reflection' of) its 'neighboring head', truly three-dimensional. ...We can induce current into the one [coil] from the other by means totally unintelligible to us, but to which we give the name 'electromagnetic induction'. But if I place one coil with its axis at right-angles to that of the other, there is no induced voltage. It is as if the two circuits lived in different worlds... What is the meaning of perspective in a four-dimensional space?

[T]he mirror really is itself, for it changes hands for you as you go through the mirror and changes the motor to a generator at the same time.

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.

West Germany branched... into... another new topology with a large-scale demonstration of the '' system... Permanent s were used to provide the lift from the underside of a ground rail. Guide wheels were used to control the gap. The philosophy... better to provide a lifting force of 120 per cent of the vehicle weight and run the wheels on a 'ceiling'...

I shall always believe the force of induction to be sheer magic in its own right!

The research director of Linear Motors Ltd told me in the late 1970s that he had then listed over one thousand different applications for linear motors. By this he meant that motors had been manufactured and sold for that number of different jobs. The most common applications included sliding doors, traveling cranes and conveyors. The items that were moved varied from 0.1 mg... to over 5 tonnes.

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.

[T]here is still no outright 'winner' in the High-speed Transport Game. Yet Japan Air Lines, Japanese National Railways, Transrapid (in West Germany) and British Rail all made advances in... versions of Maglev and linear motor propulsion in the mid 1970s. ...[E]xciting activities in university departments continued into the 1980s and a great deal of this was an extension of the topological developments of the 1960s. Surely the point of no return was passed..? There could not have been a continuing stream of wrong answers from... research departments... as was forecast by the prophets of doom of the late 1960s.

[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.

I built my first linear motor in 1948 and wrote my first paper on the subject in 1954. The Gorton experiment took place in 1962. The first model of a tracked hovercraft was publicly demonstrated at Browndown in the summer of 1966. We... conquered the long pole pitch problem in 1969. We were on the track of very far-reaching experiments with the emergence of a 'magnetic river' following Transpo 72 in May of that year. We were aware of the feedback amplifier type of magnetic suspension and of the cryogenic method (superconductor).

[In] the first efforts of Fred Barwell and myself to try out the feasibility of linear motor drives for railways... we built an 80-foot track in the laboratories of Manchester University... Having put a seat on this vehicle and given rides to daily newspaper reporters (acceleration 0.5 g), we had all the publicity we needed...

Where to begin is obvious—with Michael Faraday... But we must proceed rapidly, jumping 70 to 80 years to [Alfred] Zehden (1902) and to Bachelet, then on to Kemper (1934) (surely the 'father' of Maglev), on again to Bedford, Peer and Tonks (1939) for induction levitation and finally to the Westinghouse 'Electropult' of 1946, the first high-speed linear motor ever to be built.

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.
