Quantum theory is one of science’s most thrilling, challenging and even mysterious areas. Scientists such as Planck, Einstein, Bohr, Heisenberg and Schrödinger uncovered bizarre paradoxes in the early 20th century that seemed to destroy the fundamental assumptions of ‘classical physics’ – the basic laws we are taught in school. At the sub-atomic level, one particle seems to know what the others are doing, and according to Heisenberg’s ‘uncertainty principle’, there is a limit on how accurately nature can be observed. And yet quantum theory explanations are amazingly accurate and widely applied, explaining all of chemistry and most of physics.
