The new edition of the free physics text in pdf format
is now online at
The new edition includes many new topics, pictures, puzzles
and tables; it keeps the promise to be fascinating and
challenging on every page.
The text now explains the geometric phase and its uses
in optics, the limited, three-dimensional colour space of

space of mantis shrimps, the fascinating physics of the human
voice, the singing of high-voltage lines, the knots possible
in Maxwell's equations, and the reasons not take Descartes'

the finiteness of the speed of light.
The text also tells how to build a mirror that moves almost

Enjoy the reading!
