>When my colleague asked me this question, it took me ~2 min. to remember 1 Newton's law... :) BTW, how it's called correctly in English?
Newton's First Law (of Movement? or Motion?)
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
