物、ヒト、画像はどのように動くのであろうか。なぜ、動くのであろうか。
動きとは何か。

虹はどのように発生するのであろうか。物を浮遊させる方法は?
相対性理論でタイムマシーンは可能?自然界最大の力は何?
真空は空? 物理の未回答の問いは何であろうか。

立ち止まって考え込むことは間違いない。

The latest edition of the free Motion Mountain physics text
can be downloaded at

	       http://www.motionmountain.net/japanese.html

In total, over 1200 pages lead through the whole of physics,
from classical mechanics to relativity, electrodynamics,
thermodynamics, quantum theory, nuclear physics and
unification.

The eighteenth edition adds more about the echolocation
capabilities of bats and humans, describes the puzzle of
Einstein's last birthday present, gives more details on
rainbows, introduces the pearl necklace length contraction
paradox and presents the Einstein-de Haas effect and the
Barnett effect.  The text now provides the classification of
rocks, shows how to use the high voltage from a computer
monitor to make things levitate, introduces magnetoreception
and the sensing of electrical fields, explains the Richter
scale for earthquakes, gives an introduction into the
behaviour of solids, liquids and gases at lowes temperatures
and presents the potentially toughest challenge of physics.
Numerous figures, photographs and puzzles have been added.
The section on special relativity and several other chapters
have been improved thoroughly.  Over 60 pages of new
material have been added, often triggered by remarks and
suggestions of readers.  A warm thank you to all of them.
If you find a boring page, do complain - I'll change it.

Enjoy.
