The Book Meme.

Julia has tagged me with this Book meme.

Here's how to play:
1. Pick up the nearest book.
2. Open to page 123.
3. Find the fifth sentence.
4. Post the next three sentences.
5. Tag five people, and acknowledge who tagged you.

The nearest book is one I'm using for reference. It is titled 'Propulsion Without Wheels' and was first printed in 1966. Written by E.R. Laithwaite D.Sc., Ph.D., C.Eng., F.I.E.E. Fel. I.E.E.E., the then Professor of Heavy Electrical Engineering at Imperial College, University of London.
This edition is a 1972 reprint.

E.R. Laithwaite, 1921-1997, is a personal hero, and one whom I consider a giant in Electrical Engineering upon whose shoulders we stand.

There are others who disagree.
To them I say; There are more things in heaven and earth, Horatio,
Than are dreamt of in your philosophy.

The book is about the potential of the device known as the Linear Induction Motor, an example of which is televisored below.

The excerpt:

This being so, a linear single-phase machine with end springs will oscillate, continuously once started, provided the conditions for single-phase operation are fulfilled. As each spring reverses the velocity, so the driving force is automatically reversed. Since the conditions for back-to-back oscillation and for single-phase running (G > 1) are the same, a linear motor which will oscillate when connected for back-to-back operation will also run when connected as a single-phase machine, and vice-versa.
