Give the definition of Special Relativity (of Einstein).
Rules for the game:
(1) Don't check out any dictionary or books, only write it down by your memory.
(2) Don't look into the definitions given by participants here until you've posted yours.
@oristarA,
I'm tapping out before I can even participate. Physics on this level is above my mental paygrade.
Mine:
Special Relativity: a physical theory of relativity based on the assumption that the speed of light in vacuum is a constant and the assumption that the physical laws are invariant for all inertial systems.
---------------------------------
I then checked out my dictionary and it says:
Special Relativity: a physical theory of relativity based on the assumption that the speed of light in a vacuum is a constant and the assumption that the laws of physics are invariant in all inertial systems.
Well, not that I'm good in knowing this, just because I rechecked my memory of the definition about a week earlier. I'm unsure about three question:
1) Why did the lexicologist use "in a vacuum" but not "in vacuum"? Which is correct?
2) Is "the physical laws" equivalent to "the laws of physics"?
3) For or in, which is correct?
Stumble It!
