Science & Mathematics - 6 December 2007

I am a little confused on how I should start this problem. I assume you use integrals but I don't know how. The problem is,
The velocity of a moving object at time t is given by v(t) = e^t/((e^t) +1) Find the position s(t) at time if s(0) = 0.

s(t) = ?

I realize this is a shot in the dark, but I am looking to read in binary information from a microcontroller. Either a string of bits or 8 pins of the microcontroller will each be a bit of the number. Either way works. I need a chip that can read in that info and take care of all the logic behind turning the binary number into a LED display. ANY help or points would be greatly appreciated.

I think I heard that we are in one of the spiral "arms" that radiate from the centre of the galaxy. Is this true? If so how were they able to come to that conclusion?

I we're nthink we are because all of our cells are the same, we're just a tiny bit more evolved but we're still 'animals'. But people think its terrible to be called an animal because theyre dirty creatures that roll around on the ground something lol. we arent exactly some sort of new species, most christians think we are because of the god crap but i dno i dont think so. what do you think?

Valuable coins kept by the Treasury at Fort Knox are stored in sealed identical chests. Each chest has two compartments, filled with equal amounts of gold coins and equal amounts of silver coins (but numbers of gold and silver coins are different).

According to the books kept by the Treasury there should be 500,000,000 chests. But, alas, only according to the books. The audit revealed, that despite all inspected chests remained properly sealed, total amount of coins in all chests are:
327160698919750151 gold coins, and
981482103259250362 silver coins.

Apparently someone stole several chests full of coins.

Oh, yes, the methane emitted by cattle is again, being touted as a source of the 'green house gasses' causing the atmospheres warming.
Question : What about all of the cities 'human' sewage processing facilities / plants? Should the scientists be working on ways to harness this escaping methan gas, and 'pump this into the homes'? This will provide heating, cooking, etc. and eleminate the earths warming up to the point where the oceans start flooding cities i.e. New York, Boston, Los Angles, San Fransisco, New Orleans(again), Miami, etc.

So I hear there is a hole in each pole of the earth by some guy whose in some weird religion or something. He says that there is a whole nother civilization under the earths crust. So I say "what like in the descent?" and he follows. "No, but how do you explain all the new species of fish we keep finding?" Well, lets see. We haven't discovered all of the species on land let alone the 70% water that makes up earth.

Anyone know what the hell he's talking about or if I can see these holes on google earth?
