A key insight of general relativity is the view of the universe as a four-dimensional geometric space. Gravitation and other forces within physics are explained as properties of the geometry. Analogously, string theory includes many dimensions, as many as ten or more, in an effort to explain all the forces of the universe. Given the geometry…

Mathematician love to chase after conjectures, which are unsolved mathematical claims. There are thousands of conjectures, but the tough ones are sometimes famous. For example, the Poincare conjecture makes a claim about shapes in three dimensions, as part of the field of topology. It was recently solved by Grigori Perelman, and resulted with him being awarded then…
