Light speed ...fact or theory

Has a practical experiment ever been carried out to prove that nothing travels faster than light or is it all mathamatical theory? Thinking of it, what kind of experiment could be tried?

Why is Pi wrong?

It should be exactly 3 but it's slightly out. How did that happen? Could there be somewhere else in the universe where it is 3?...

Vectors A and B have equal magnitudes of 4.98. If the sum of A and B is the vector 6.34j, determine the angle between A and B.

It is not 101° , -101° , 79.1° and -79.1° .

Two vectors A and B have precisely equal magnitudes. For the magnitude of A + B to be 78 times greater than the magnitude of A - B, what must be the angle between them?

not 130° not 178°

Wind power in the uk

Ok so solar panels would be pointless here, but we do have a lot of wind so why have we not got more wind turbines everywhere? Cost of building or eyesores that would spoil the scenery?
