The mathematician H. Minkowski gave a mathematical form to the special
relativity theory in 1907. A line involves only one dimension. We can locate
any point on a sheet of paper by measuring from that

Einstein illustrated the basic idea of general relativity with an imaginary
experiment. Suppose a lift is at rest in space. If a ball is released within the
lift, it will float in space and not fall.
