Quantum mechanics is a bizarre topic in science, and the many scientists who specialize in this field usually say the same thing about it. Richard Feynman once said” I think I can safely say nobody understands quantum mechanics.” Niel Bohr, who was the father of quantum physics, chimed in and said ” If quantum mechanics hasn’t profoundly shocked you, you haven’t understood it yet.” In his speech, Jim Al-Khalili describes how European Robins (the birds) migrate in a direction that might link the way they navigate to the earth’s magnetic fields on a quantum level. Complicated but very thrilling, alluding to understanding biology, chemistry and physics in quantum level. Imagine if he is right! This will shed light on many important fields in the future such as quantum computers, medicine and the origins of the universe. Experiments and tests are still being conducted in this field since it first started in the 1920′s and I think in order to understand quantum mechanics, we have to use our imaginations because in the quantum world some major principles do not necessarily apply.
