Dynamic equations and time scale analysis offer a unifying framework for the study of systems evolving over time, whether in continuous, discrete, or hybrid settings. By integrating differential and ...

Time feels like the most familiar thing in the world, yet it hides one of physics’ hardest questions: why do we only remember the past and never the future, and why do broken eggs not leap back into ...

Mathematicians finally understand the behavior of an important class of differential equations that describe everything from ...

Maxwell’s equations of electromagnetism and the Euler equation top a poll to find the greatest equations of all time. Robert P Crease discusses the results of his reader survey First among equals – ...

The Einstein International Year of Physics is drawing to a close and if there's one thing the average punter now knows, it's that Einstein came up with E=mc 2. Is it the number one equation of all ...

Physicists have demonstrated that waves can bounce off boundaries in time, not just in space, producing signals that behave ...
