Nature's Laws of Conservation-printing

"The key to the relation of symmetry laws to conservation laws is Emmy Noether's celebrated Theorem. ... Before Noether's Theorem the principle of conservation of energy was shrouded in mystery, leading to the obscure physical systems of Mach and Ostwald. Noether's simple and profound mathematical formulation did much to demystify physics." - Feza Gursey ( 1921, Istanbul - 1992, New Haven, Connecticut )
