Heisenberg group by 90°. The other reflections are "xyx" and "yxy", and rotation by 180° is "xyxy" (="yxyx"). The Lie algebra formula_16 of the Heisenberg group formula_1 (over the real numbers) is the space of formula_18 matrices of the form with formula_20. The following three elements form a basis for formula_16: The basis elements satisfy the commutation relations: The name "Heisenberg group" is motivated by the preceding relations, which have the same form as the canonical commutation relations in quantum mechanics: where formula_25 is the position operator, formula_26 is the momentum operator, and formula_27 is Planck's constant. The Heisenberg group formula_1 has
The Tao of Physics a whole culture that subscribed to very similar ideas. Heisenberg said that this was a great help for him. Niels Bohr had a similar experience when he went to China. As a result of those influences, Bohr adopted the yin yang symbol as part of his family coat of arms when he was knighted in 1947. "The Tao of Physics" was followed by other books of the same genre like "The Hidden Connection", "The Turning Point" and "The Web of Life" in which Capra extended the argument of how Eastern mysticism and scientific findings of today relate, and how Eastern
