Scientists Crack Quantum Physics Puzzle
Scientists have re-investigated a sixty-year-old idea by the American physicist P.W. Anderson and provided new insights into the quantum world.
Quantum physics explains how the world’s building blocks such as atoms or electrons are put together. Everything we see around us is made up of atoms and electrons which are so small one billion atoms placed side by side could fit within a centimeter.
Because of the way atoms and electrons behave, scientists describe this behavior as waves. In the research, scientists looked at how waves can go through a landscape containing obstacles placed in random positions.
Anderson initially developed this idea to describe electrons in semiconductors. His insight greatly contributed to the development of computer chips and electronics.
“His work describes a common phenomenon that happens for all kinds of waves, be it light waves, ocean waves, sound waves or quantum-mechanical waves,” says lead researcher Maarten Hoogerland from the University of Auckland.
