Books on Amazon | I 117 Relativity Theory/Einstein/Feynman: every thing that has energy also has mass. Mass in the sense that it is subject to the gravitational effect. Even light that has energy, has a "mass". I 217 Def Relativity Principle/Newton: "The movements of objects within a given space are the same in relation to one another, whether the space is at rest or whether it moves constantly on a straight line." I 218 Feynman: the Newtonian laws appear to be the same in a uniformly moving system. I 235 Twin Paradox/Feynman: one might think: If by the movement of one twin that one ages more slowly, that because of the relative movement of the two to each other both should actually "become younger"? FeynmanVs: there is an asymmetry in the twin paradox: the man who experiences the acceleration at the start and at landing is the one who ages more slowly. The other one is in a completely different situation. Only the one who has moved can come back. That is a difference between them in an absolute sense and it is also true._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
