thank you.. this website strangely is in my favorites list though. i have no idea why i never seen it ! :?

Hi everybody. Me and a friend of mine are going to be EE majors this year, so we thought we'd build a 3D printer from the very beginning. Of course we're going to have some instructors helping us out but I need some information about the whole thing before offering anyone anything! First of...

Bingo .. yeah sorry my bad, i was wrong at the first place exactly, we're sure about 1k of them, yes we can and we have to. The tricky part is how to find the forth and the third powers, perfect fourths are sort of squared powers, now we need 3hird powers as well !

great explanation thanks but: im afraid N\neqn2,n3,n4 why you guys are insisting on this.. n2= 1,...,1000 are eligible so we already have 1000 numbers to count for n squared for n3 couple more to count for n4 related to the n2 so we split them up so we'd have to get 1 thousand and some...

my misunderstanding about behaviors of dark matter, i remember an episode of HOW THE UNIVERSE WORKS that they were saying some galaxies seemed to be disordered it was caused by dark matter, their(galaxy's) lights couldn't get directly through it, they were forced to get around it.. that's why i...

@mark44 we actually have to count them... we are not allowed to sum'em up they are each different terms of this problem after we got the answers we do this: set of answer={n2\capn3 \cap n4}

wow thanks so here's the part i don't really get .. how it doesn't interact electromagnetically? based on that its not following the rules of physics as other matters would do. because even energy cannot go through it, it should be intact am i right? then can we trace its root?

and the dark matter basically make stuff stick together is that right? galaxies would stay stiff by dark M and the universe being made of galaxies is expanding caused by dark E.. why is that? im sorry if i ask basic question I am new to cosmology

i think only the words are different i wanted to have a little discussion over here about it if that's not a problem!

"BLACK MATTER" what is it? wheres it come from? "BLACK MATTER" what is it? wheres it come from? how is it related to its opposite force the BLACK ENERGY? why is it so powerful? why and why indeed LIGHT wouldn't go through it? put your thoughts here and let's if we can come up with...

aha now i see. so twelfth power would satisfies all three? for 4 nd 2 we take 4 andwe just multiply 4 and 3 to get 12 which is good for all ! i got it :D thanks

hopefully everybody is saying the same thing .. Kaku's blog called "big think" is a great futuristic place !

i meant the BB being a start point might not be true..as Prof. Kaku explains it i did happen but it wasnt the first time

thats exactly what I am saying , you check your ideas and take the best one ! the BB idea has become a bit old it used to be the best idea!.. there are strong possibilities that this event is a cosmic cycle it never stops and it never starts ! if its true then the universe is a very strange...

i agree with you .. I am completely aware that being in Calculus BC is just not enough to making claims about these stuff .. and how could you be that sure about the truth? im willing to believe the truth that's why I am here,so why would i be uncomfortable with it?
