A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

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 ...

Mathematical physics is an interdisciplinary field that employs rigorous mathematical methodologies to elucidate and model physical phenomena. It draws upon diverse areas such as differential geometry ...

A growing body of theoretical and experimental work in physics is converging on a striking possibility: time, the dimension humans experience as a constant forward flow, may not be a fundamental ...

Jason Lotay explains how mathematicians studying special geometries are collaborating with physicists to explore M-theory, an 11-dimensional description of the world that unifies the various string ...

Surprising as it may sound, 107 years after the introduction of general relativity, the meanings of basic concepts are still being worked out. More than a century after Albert Einstein unveiled ...

On The Road to Reality : A Complete Guide to the Laws of the Universe, by Roger Penrose. The mathematical physicist and cosmologist Roger Penrose, now professor emeritus at Oxford University, is best ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

In this paper-covered pamphlet of eighty pages, which is sold for saxpence, Prof. Rice sets forth the doctrine of relativity: and not only this, but also (as prelimiriaries to it) the principles of ...
