191 'Most Beautiful' Theories in Science Relativity, theory of evolution top the list By Mark Russell, Newser Staff Posted Jan 16, 2012 4:43 PM CST Updated Jan 21, 2012 7:00 AM CST 69 comments Comments The Edge has published 191 ideas about the most elegant and beautiful theories of the universe and life. (Creative Commons) (Newser) – Every year, the website Edge poses a big, open-ended question to leading scientists. This year's query—"What is your favorite deep, elegant or beautiful explanation?"—received 191 answers covering a wide range of ideas, with Albert Einstein's Theory of Relativity and Charles Darwin's Theory of Evolution receiving the most replies, reports Reuters. Some interesting responses: "Darwin's natural selection wins hands down," writes Richard Dawkins, unsurprisingly. "Never in the field of human comprehension were so many facts explained by assuming so few." Einstein's Relativity: "This central idea has shaped our ideas of modern cosmology (and) given us the image of the expanding universe," writes one theoretical physicist. The human brain's fundamental irrationality: "An ancient brain system called the basal ganglia, brain circuits that consciousness cannot access" control our major life decisions, one neuroscientist writes. Group polarization: Interacting with others does not mellow our opinions, but pushes us to extremes in politics and other issues. "The surprising thing is that the group as a whole becomes more extreme than its pre-discussion average," writes a psychologist.
