Life and Quantum Physics

Quantum physics rules many parts of the universe: it was essential for the start of evolution and it governs all of molecular biology and biochemistry, for example the function of DNA, proteins, and enzymes. It is fundamental to the cornerstones of life-the harvesting of energy from the sun and the utilization of energy in cells. Over the next 400 million years gravitation caused the hydrogen and helium gas to break up into dense hot regions forming the first stars and galaxies. Quantum physics describes how chemical bonds work, why hydrogen and oxygen spontaneously become water molecules, and what it is that keeps oil and water from mixing. Quantum physics explains how electrons move around an atomic nucleus, and what it is that drives transformations of matter.
