It is a simple feat of scientific electrical engineering — only expensive — blind, faint-hearted, doubting world.

Einstein's relativity work is a magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors.

Throughout the infinite, the forces are in a perfect balance, and hence the energy of a single thought may determine the motion of a universe.

Our senses enable us to perceive only a minute portion of the outside world. Our hearing extends to a small distance. Our sight is impeded by intervening bodies and shadows.
