Work
For a long time, physicists assumed that various symmetries characterized nature. In a kind of “mirror world” where right and left were reversed and matter was replaced by antimatter, the same physical laws would apply, they posited. However, symmetries had been proven to be violated at times. In 1960, Yoichiro Nambu formulated a mathematical theory for understanding spontaneous symmetry violations, providing a basis for better understanding elementary particles and their interactions.
Nobel Prizes and laureates
Six prizes were awarded for achievements that have conferred the greatest benefit to humankind. The 12 laureates' work and discoveries range from proteins' structures and machine learning to fighting for a world free of nuclear weapons.
