I know a geometry method , you can draw a regular heptagon , than each exterior angle is
I can't get to it ,either . It's way too far for me .
I heard that E8 was solved by a group of 18 scientist , want to get some information about it . (What the heck is E8 , anyway)
maybe space is elastic. XD
what is x anyway?
I've tried for an hour to find a shortcut ...no inspiation ,,,looks like the tree diagram is the final solution.
If M theory is right , then the universe is wrapped by a membrane , there's "outside" of the universe.
We'll , perhaps , never see the day of revealation . Though I am dying to see what's outside the universe and why it's expanding.
6=2x3,
There are two kinds of integers 2k and 2k+1 , thus it can be divided by 2
There are three kinds of integers 3k , 3k+1, 3k+2 , thus it can be divided by 3
you should discuss two situation ,if p is smaller than the peak , as p increases ,R also increases , if p is larger than the peak
as p increase , R decreases.
OMG, this happens when they have acceleration? Pretty Cool actually .
In my opinion maybe universe is like a room without air, and all the stars and galaxies are like a pack of air. The Big bang made them be released , the stars and galaxies are moving aways , like the air trying to fill up the whole room.
It's so strange~ I graph the
on my computer , it's like a parabola!!!!!Yeah , I find it between 3 and 4 too
It's a homework from my friend , it said , find out and intersection numerically ( y = 1.4^x , y = −x^2+4x+1 )
oh ,right . lol , I am so stupid.
I know , Ricky. I mean even if all galaxies and stars are moving away from the earth ,that cant determine the universe is expanding , because their unstable movement.
So this is a theory , it holds for what we know . Have they found out the Structure of the universe? I mean the position of galaxies are random or intentionally placed.
If the positions are stable , then what keep them in place
This question isn't in the textbook
I want to know , Whether the position of galaxies , stars in the universe are stable , not moving around .
The method to determine whether the universe is expanding is through the redshift or blueshift
If the positions of galaxies in the universe arent relatively stable, then how can they determine the expand through redshift or blueshift?
well , if a timber cut in 7:2 . you can think like this , 7 blocks of wood belong to A , 2 blocks of wood belong to B , then what is the total blocks of wood , the wood is cut in 7+2=9 blocks , then how long is each block , 828/9. Then how long is 7 blocks together (larger) , (828/9)*7.
Outstanding calculation...omg..
It can be a pattern , if you want . Solve the equation with 6th power.
it can narrow the range and eliminate the number of primes whose product is the number.
I have to work on this some more .
Maple is a software can handle mathemtical calculation and stuffs
