$ 'GR cannon-ball "feelings"'; By jOE Fischer
[Who cares a cannon-ball has "no feeling" off a TOWER of PiZZA.] [There is NO cannon-ball, in GR (NO mass RELATED to G_uv=T_uv).] brian a m stuckless Henry Haapalainen wrote: "Joe Fischer" kirjoitti viestissä ...

Simply more kooky nonsense. Acceleration has a well defined meaning in physics as rate of change of velocity. Or rather well defined in Newtonian mechanics. Physics changes quite often. And velocity also has a well defined meaning - rate of change of position. I seem to remember a well accepted theory that predicts traveling 10 light years in one year at .9 c. I had the perception that you embraced General Relativity, but if you don't like the idea of time slowing, I must have been wrong. Stick to the usual meanings and you may be able to get somewhere. Rest of rubbish snipped. Bill Good advice, never try anything new, just do the same forever. Joe Fischer Acceleration is not always acceleration. Observer in a free-fall does not feel any acceleration. Henry Haapalainen |

Observer in a free-fall does not feel any acceleration. Henry Haapalainen You and others seem to be unable to deal with the concept of a definition. Terms such as velocity and acceleration are defined terms. Velocity and acceleration are defined as vector quantities as is position displacement. Simple well defined math (its called differential calculus) allows us to take the concept of the position of a body and its displacement and define velocity and acceleration. A definition cannot be wrong. It can be inconsistent or useless by not corresponding to anything important in the physical world. But it cannot be wrong. BY DEFINITION a definition cannot be WRONG. |

Dear Mr. fkasner:
Please stop trying to fight insanity. He who battles insanity has it transferred to themself once the battle is over. The purpose of Usenet is for a bunch of narcissistic fraternity brats to use up all of America's precious computer memory (isomorphic to fossil fuel depletion) and bring down the General System. No meaningful dialectic is intended. Have a nice day. |
