Do the equations of physics find their way into the daily life of a cat? This is the intriguing question posed by Anxo Biasi, a researcher at the Instituto Galego de Física de Altas Enerxías. Inspired ...

Thus we get equations of motion in first approximation (gravity inoperative), second approximation (differing from Newtonian equations only in the possibility of small changes in mass), and third ...

When a German physicist returned from a health retreat 100 years ago, his ideas sparked a debate about reality, and gave rise ...

For the first time, a mathematical framework proves that Einstein’s theory of general relativity, which explains the relationship between space, time, and gravity, is in alignment with quantum ...

A convergence theorem for applying linear multistep numerical integration methods to constrained equations of motion in mechanical systems is presented. Using a differential geometric approach, ...

This series of short explainer films with Professor Brian Cox comprises six clips focused on forces, speed and motion. Each clip uses simple terms and concrete examples to explain deep concepts ...
