    understanding probability theory... Infinite monkey theorem

    You only need either an infinite number of monkeys, or infinite time. Using both is a waste. Infinite monkeys will produce <whatever> instantly.

    Where are we in the universe?

    Erm. The center of a spherical universe? The center doesnt exist. In balloon-notation, where is the cetner of the surface of the balloon? Anyway; the universe doesnt look closed to me. Flat at best.

    Relative position of the Earth

    Though the ecliptic is used to impose an arbitary up/down. Does the 'galactic ecliptic' and the regular kind line up at all?

    Which color is the fastest?

    You got that one inverted Mokmo. Incidentally. Red light has a longer wavelength. And things moving towards you are blue shifted.

    Philadelphia Experiment

    No. Its a big load of bollocks thought up by someone on the verge of insanity.

    Can global warming effect Mars?

    "Concerning the atomic energy from Earth's core, I think "nuclear reaction" has the wrong connotation. Nuclear decay would be more accurate, as far as my understanding of it goes." I agree, for the most part. But Forumers might find this interesting; there does exist one natural 'nuclear...

    If we can speed up light

    You can change the speed of light, but c is a constant. (hopefully)

    recommended reading of non-fiction?

    Ahhh... feel the Feynman love. Greene writes well imo, but all of his diagrams in The Elegant Universe sucked. Might have been improved in later editions. Not maths or physics, but if you have never done a proper course in evolution, it is absolutly *essential* that you read at least...

    Pouring ice

    Perhaps it lacked nucleation sites? And only when it hit some stuff in the galls could it crystallise?

    Artificial Gravity

    No, then. A gravitationl field is a gravitational field, and you cant fake it. No more than you can with any field. There is no magical source of gravity, and certainly no currently identifiable way of producing a negative gravitationl field.

    Idea about gravity and space travel

    The 'speed of time' concept is a strange one. All objects travel at lightspeed through spacetime, in thier rest frame... methinks. As one speeds up towards c, time 'slows' and it takes you progressivly less local time to get anywhere; if you are going at 99% c, itll take.... about 1/10th of a...

    physics/chemistry/math in university...your stories/experience/advice?

    If you are going to do physics, you *have* to love mathematics. Popular physics is very exciting and interesting, but it has ah heck all to do with degree physics. Does the sound of complex number integration excite you? Tensor theory? Legendre polynomials? It doesnt me. Which is why my...

    Why do we age?

    Rather than talking about mechanisms etc, ill go for a different tack. We age because it is advantageous to do so. Not aging is a constant stuggle against entropy, and hence difficult- and there is no advantage to doing so. It takes 12 or so years to get to the point at which one can...

    Artificial Gravity

    Microgravity, surely, is defined as the situation in which objects act as though there is no gravitational field present? ie an inertial frame of constant acceleration like an elevator in freefall? If you could 'exclude' the field, then that would not be microgravity, but actually no gravity at...
