SperM.hotmail.com wrote in sci.physics.relativity: Alas, velocity = displacement / time and speed = distance / time Bravo Moortel! Only a few years ago you and your brother zombie Sam Wormley were rather confused about "velocity" and "speed" - both of you believed that, although in his 1920 "Relativity" Einstein says the velocity of propagation of light "varies with position" in a gravitational field, the speed of light remains constant. So Master Tom Roberts had to teach you additionally: Sam Wormley wrote on sci.physics.relativity: "Valev confuses *velocity* of light with *speed* of light!" Tom Roberts explained to Sam Wormley and Dirk Moortel: "AFAIK Einstein basically thought in German, which does not have different words for "speed" and "velocity" ("die Geschwindigkeit" is used for both). Certainly his "velocity of propagation" could be phrased as "speed of propagation" without changing the underlying physics." Tom Roberts Pentcho Valev |

Tom Roberts : : Pentcho Valev Einstein's original paper used "V" as the velocity of light, one would have to wonder why he did not use G for Geschwindigkeit. Then again English capitalises pronouns and Deutsche kaputalizes nouns. Dork Van de local village idiot calls these semantics "fumbles" and writes to his web page anything he personally disagrees with, expecting others to see it his way. He is unable to clearly and logically state what it is he finds to be a fumble. Perhaps the light goes to A from B rather than from B to A, both of which are backwards.
