But the particles that constitute you or your toothbrush are not predictable with that sort of certitude where they will be at any given time or when they appear at a given place!
Quantum Physics studies how the tiny particles like electrons, protons and atoms that constitute everything behave. Quantum Physics sobers us down quite a bit when it is a question of being sure of things. It teaches us not to be so definite and deterministic. It comes out with mind-bending mathematics and unbelievable concepts almost bordering Vedanta. Dr. Niels Bohr, a giant among Quantum Physicists, famously said: “Anyone who is not shocked (by the concepts of Quantum Physics) has not understood it.”
For all that, Quantum Physics is not an esoteric theory. It comes with redoubtable experimental back up and unfailing proof. Continue reading
