OK, this is the theory as I understand it. The big bang was not the first or last one to happen. All the matter of the universe was slowly sucked in, it came into a big ball and exploded and out came planets and atoms with circling electrons, and stars, and everything randomly happened. And the universe is still expanding. This seems silly to me.

I have an urgent problem need to be work out,
the problem is:

"Prove if z1,z2,z3 are distinct points,and w1,w2,w3 are distinct points,then the Mobius transformation T satisfying T(z1)=w1,T(z2)=w2,T(z3)=w3 is unique.[hints:S is another
such Mobius transformation and consider the fixed points of composition T^1.S]"

If nobody can solve this question,can anybody suggest a better website to do it such as online tutor...

Earthquake intensity is measured by the Richter scale. The formula for the Richter rating of a given quake is given by "R=log[I/I0]" where I0 is the "threshold quake", or movement that can barely be detected, and the intensity I is given in terms of multiples of the threshold intensity.

An earthquake was reported to have a Richter number of 5.99. How does the intensity of the earthquake approximately compare with the reference intensity?
