String Theory....

When physicists started to combine the two titans of physics, meaning Quantum Mechanics and Relativity they encountered a huge problem. The two theories don't fit!. So they began a hunt for a new theory involving hyper-spaces and strings (and much much mathematics too) and that theory is string theory. It just basically says that everything (matter and energy) is composed of tiny vibrating strings which change structure when you pull them. It also says that there are "multi-verses" and our "universe" is just one of them.

All you need to start doing physics!

Professor Susskind's extraordinary book to help people who want to do physics but shy away from the mathematics.

Professor Walter Lewin Rocks

This guy makes physics amazing to study. Its as if he is not teaching physics at all. He is my idol when it comes to Professorship.

Dimensions

OK how many out you can see the fifth dimension? None right? But what if I ask you of you can visualize the second dimension? Almost all will answer that they can. Wrong! You aren't seeing the second dimension. You are seeing a 2-D frame embedded in 3 dimensional space. Our minds are made up only to sees the third dimension and stuff embedded in it. Give it a thought.

What runs the world...

I believe that the universe works as it is because of these two equations.
The Einstein field equations and the Schödinger equations.
Any body else agrees?

Fermat's last theorems.

OK I know this is not related to physics but it is puzzling.
Fermats last theorem has been one of the most puzzling thing in mathematics. It simply states when any two numbers are raised to a power n and added and it equals another number to the same power for n >2 there is no integer value for B.C.
Find the proof if you can and get a hundred thousand dollars!

Relativity

Space...
Time...
Mass...
Gravity...
All connected by a single theory.
Relativity is the symbol of intelligence.
