Three decades ago, a British documentary series named Connections aired, which showed viewers how various scientific achievements and discoveries were really interrelated, no matter how disparate they ...

If the World Science Festival's panel on string theory tackled the question of whether the math behind it could be a reliable guide to reality, its panel on the Limits of Understanding seemed to ...

For the last 40 years, a dedicated group of theoretical physicists has been beavering away on an ambitious project to create a quantum theory of gravity and unify the four forces of nature. Using ...

Physicists looking for a way to test their theory about strings might make more progress if they tangle them up. String theory — equations that aspire to explain all of nature’s particles and forces — ...

For decades researchers have tried to wrest testable predictions from string theory, the leading candidate for a more fundamental understanding of the universe. Now physicists say they have used one ...

Mathematicians are exploring a string duality between F-theory and heterotic string theory in eight dimensions. Simply put, string theory is a proposed method of explaining everything. Actually, there ...

The final installment of a three-part NOVA series about "String Theory," a new branch of science that seeks to explain nothing less than how the universe works, airs on PBS. Ray Suarez speaks with ...

You may not have heard of knot theory. But take it from Bill Menasco, a knot theorist of 35 years: This field of mathematics, rich in aesthetic beauty and intellectual challenges, has come a long way ...

Via Museum of Natural History D.C. Stop. Look around. All things, visible or not, are made of particles so tiny that many find their sizes difficult to comprehend. Far removed from our everyday ...
