La nuova versione del libro di fisica e`accessibile (come sempre
gratuitamente).
Aggiungo le novit� in lingua inglese, che e`anche la lingua del testo.
The new revision of the free Motion Mountain physics text can be
downloaded at

The 17th revision adds pictures of our environment in the universe at
large
scales, explains how to enjoy Heron's fountain, gives an improved
explanation
of solitons, tells about the idea of using an elevator to get into
outer
space, shows how a maximum force in nature explains the darkness at
night and
predicts the size of the universe, tells why relativistic length
contraction
is not a danger for snow-boarders, shows how the world looks to the
colour
blind, explains the physics of tsunamis and tells how to use Galilean
mechanics to earn over 1 million pound sterling per evening. A 5-line
summary
of modern physics is given and a prize for the first solution to a car
parking
problem is offered.
The text also explains and how you can build a loudspeaker with an
infrared
laser beam and no moving parts at all, by modulating the beam and
heating the
air. The device, invented in 1992 by Martin van der Mark, provides a
way
to realize an invisible loudspeaker.
Many improvements make the text even more readable than before. The
whole
remains as surprising and thought-provoking as ever, on each of its
over 1100
pages. They lead through a structured and entertaining walk through
the whole
of physics, from classical mechanics to relativity, electrodynamics,
thermodynamics, quantum theory, nuclear physics and unification. There
should
not be any boring page.
Enjoy the reading.
