In other words, it is impossible to perform a physical experiment which differentiates in any fundamental sense between different inertial frames. By definition, Newton's laws of motion take the same form in all inertial frames. Einstein generalized[1] this result in his special theory of relativity by asserting that all laws of physics take the same form in all inertial frames. >> http://farside.ph.utexas.edu/teaching/em/lectures/node108.html [1]<< the four-dimensional space-time continuum of the theory of relativity, in its most essential formal properties, shows a pronounced relationship to the three-dimensional continuum of Euclidean geometrical space. In order to give due prominence to this relationship, however, we must replace the usual time co-ordinate t by an imaginary magnitude sqrt(-1) ct proportional to it. Under these conditions, the natural laws satisfying the demands of the (special) theory of relativity assume mathematical forms, in which the time co-ordinate plays exactly the same r�le as the three space co-ordinates. >> http://www.bartleby.com/173/17.html << where epsilon_0 and mu_0 are physical constants which can be evaluated by performing two simple experiments which involve measuring the force of attraction between two fixed charges and two fixed parallel current carrying wires. According to the relativity principle, these experiments must yield the same values for epsilon_0 and mu_0 in all inertial frames. Thus, the speed of light must be the same in all inertial frames. >> http://farside.ph.utexas.edu/teaching/em/lectures/node108.html Sue... _______________________________ And your point is ... ?

Einsteins notion of 'god' was not of a supreme being separate from the universe, but more of pantheism. But yes .. knowing the 'mind of god' is not scientific.

Pardon me. But I'll be the judge of what is clean. And, for a lot of people, if you write a book (good or bad), you become an expert just on that fact alone. I'll accept that one or two guys can be crackpots, but I began to find many more guys than I thought would be there who had their doubts. I even re-read a chapter on the wave-particle duality in a recent quantum mechanics book (the kind where equations are on every page, so it should make lots of you guys happy, and the author listed his affiliation with a university I've heard of, too) and he made a lot of qualified remarks, too. >> >>> Regarding the author...well, his description on Wikipedia sys: >>> "Bethell is a member of the Group for the Scientific Reappraisal of >>> the HIV-AIDS Hypothesis, which denies that HIV causes AIDS. >> >> Well, that's not good. >> >> His The >> >>> Politically Incorrect Guide to Science promotes skepticism of the >>> existence of man-made global warming, >> >> That is still controversial.
