I'm doing a science report and I need some answers...(I'm doing it on Venus, obviously)All I want to know is:
1) What Venus was like
2)What you guys suspect Venus will be like in oh...a million years?
Is that enough time for it to signifigantly change(If it will at all)?

What do worms eat? My friend says that they eat dead rabbit. Is that true? Could I get a cardboard box filled with dirt and put worms in it and expect to see them live?

Im a calc2 student but Im trying to do a little more math on my own. A number theory book I have is talking of prime numbers and in this section they say you need to integrate 1/lnx from 0 to x. This is a non elementary function so parts, substitution, etc will not work. I know I have to express this as an infinite series but I dont know how to do this unless its a very simple function. (I can do geometric series expansions and the like but I dont know how to do this as 1/lnx)

Can anyone integrate 1/lnx from 0 to x and explain it detailed steps how they did everything. I want to understand how the function was expressed as a series and what function it gives you. (Since the upper bound is x it should give a function, not a number...right?) Thanks in advance.

25^-1/2 = 1/√25 = 1/5

My question is, why does 25^-1/2 turn into 1/√25 ???

Where did the negative exponent 1/2 of 25 go??!!

i understand that ftl travel is not possible (at this point in human history, anyway). that being the case and that the shortest distance between two points is a straight line, do you think that at some distant time we will be able to generate enough gravity in an object (ship?) in order to bend spacetime around on itself so that an object say 25 million light years away would simply be a short step, like going through an ajoining room door in an hotel??

The 1st supersonic flight was peformed by CAPT.CHARLES YEAGER in 1974.He flew at a speed of 300m/s at an altitude of more than 12,where the speed of sound in air is slightly less than 300m/s.Suppose CAPT. YEAGER accelerated from 120m/s to 300m/s in 25.0s.What was the magnitude of his accelebration?
