I taught a physics course (in English) to Japanese students in Tokyo a
few years ago. They kept their English-to-Japanese dictionaries with
them during lectures, looking up words as needed. I remember being
horrified when I realized (rather belatedly) that the English words
"force" and "power" both translated into the same word in Japanese!
