Our Writers' Gallery features short pieces about physics by authors who are both renowned physicists and prize-winning writers. Some of these are original contributions and others are excerpts from longer works. Many are linked to more information about the authors and their work.
Gödel's Incompleteness Theorems shook the foundations of formal logic and mathematics, but its meaning remained elusive even to experts for years. Today, however, there's an easier way to see how Gödel discovered his theorems.
Many mathematicians since the time of Euclid attempted to solve a seemingly simple problem about parallel lines without success. Yet the success of their failures would reveal a whole new geometry and description of space and time.
