Source term of the Einstein field equation Thanks! I consider the following quote to be an excellent answer to my question: "Given a small ball of freely falling test particles initially at rest with respect to each other, the rate at which it begins to shrink is proportional to its volume times: the energy density at the center of the ball, plus the pressure in the direction at that point, plus the pressure in the direction, plus the pressure in the direction." Baez claims that this statement is equivalent to the usual formulation of Einstein's equation. |

Interesting topics to research in mathematical physics for undergraduates I'm sure it's just a co-incidence... ;-) |

Interesting topics to research in mathematical physics for undergraduates I think it's better to have a problem in mind rather than the techniques you want to use to solve it. You might not know which techniques should be used ahead of time! |

Source term of the Einstein field equation So I guess my concern came down to whether the active mass of an ideal gas in a container of fixed size varied in the temperature or the pressure... but they are equal up to a constant in this case. I accept the answer now. |

Source term of the Einstein field equation Lubos, I didn't have a previously existing opinion, so I'm not sure what I repeated. |

Source term of the Einstein field equation I'm pondering this answer... my concern is that Penrose might have been referring to the pressure required to keep all the energy enclosed within the sphere, and the reason I am concerned is because Feynman may have intended for the active mass to inclue kinetic energy terms. |
