Hey Inertial guy: If your supposed scientific education and aptitude (Shouldn't that be: Science Education?) is so great, why is it that you have NEVER made a "+new post" on sci.physics relative to any issue of science? The likely reason: Your only 'aptitude' is to defend whatever science GARBAGE that you were taught (sic) in college. Defending that which has been conclusively proved to be wrong doesn't stand you in good stead as a "scientist" (ha!). NoEinstein |
