Mathematical equations, from the formulas of special and general relativity, to the Pythagorean theorem, are both powerful and pleasing in their beauty to many scientists. Here are experts ...
Steven Strogatz offers a walk-through of Albert Einstein’s childhood proof of the Pythagorean theorem, and what it shows about his thinking on relativity. Skip to main content.
Developed by Amalie Emmy Noether (1882-1935), the theorem resolves questions raised by the general theory of relativity and continues to be an essential theoretical tool.
When it was published in 1915, Einstein's general theory of relativity opened as many questions as it answered. Among them is the fact that energy is not always conserved in general relativity.
Yet the mathematics of general relativity is also profoundly counterintuitive. Because its basic equations are so complicated, even the simplest-sounding statements are difficult to prove. For example ...
Noether’s theorem was particularly helpful as particle physicists in the 20th century crafted their standard model, the ...
In 1905 Einstein discovered the special theory of relativity, establishing the famous dictum that nothing—no object or signal—can travel faster than the speed of light. And therein lies the rub.
Bell's theorem, the well-known theoretical framework introduced by John Bell decades ago, delineates the limits of classical physical processes arising from relativistic causality principles ...
Einstein’s theory, called general relativity, radically transformed the meaning of space and time. Rather than being fixed backdrops to the events of the universe, space and time were now characters ...
