OKay-- acording to the LAW OF CONSERVATION OF ENERGY, which is one of the basis for our foundation on the laws of physics-- "Energy cannot be created from nothing" --that is, there is no free energy. From what I understand, matter can be considered a form of energy-- it can be converted to energy ; ie: A football player eats a carb-loaded meal then night b4 a big game-- he has more energy to expend in the big game. So, if energy is produced by conversion from matter then what fuels the seemingly ENDLESS AMOUNT of energy that is expended by gravity? Where does the energy come from to keep a moon swinging around us, or to pull an apple to the ground? Can anyone enlighten me on this? Maybe my logic is skewed. What fuels gravity? Thanks!

every time i roll my die, there is a one in six chance i will get any given number.

but is this probability true?

have there been any really long term research done?

if i roll for an hour and count the results, will any number stand out more?

if i roll for years?

dice might be bias, what about random number generators.

do the real world results match the probability?

Hi there,

The tetrahedron OABC is such that OA=a, OB=b and OC=c. The point D is the midpoint of BC and E is the midpoint of OA. The line DE is a bimedian of the tetrahedron.

Find the position vector of G, the midpoint of DE (i.e. the vector OG) and show that G is also the midpoint of the other two bimedians of the tetrahedron.
This question has got me stumped. I did Vectors a long time ago at school but nothing about bimedians.
Any help would be warmly appreciated.
Thanks

I take online surveys. For each one I take, I get entered into a sweepstakes. I'm not sure what my odds are, let's just say 1:1000. My question is: do my odds of winning go up with each survey I take, or are my odds always the same, starting over each time?

Sweeping the universe listening for radio waves seems like such an archaic tactic. Presuming we are looking for intelligent life forms (perhaps intellectually superior?) - why radio waves? There would be such a small window of time in the aliens' history where radio waves were actually used, so aren't we being a little narrow minded? What other methods are there?
