Re: GEOM Proof. Incidence geometryProof by contradiction: The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #4 20120830 10:30:19
Re: GEOM Proof. Incidence geometryHi TARAJS; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #5 20120830 16:59:53
Re: GEOM Proof. Incidence geometryhi all,
If p exists then the lines are not parallel (definition of parallel) You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #6 20120830 21:50:39

Re: GEOM Proof. Incidence geometryI have nothing against the proof. Just the definitions you quoted.
