One of the most basic assumptions of fundamental physics is that the different properties of mass -- weight, inertia and gravitation -- always remain the same in relation to each other. Although all ...

There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”. However, Lorentz invariance – the theory that the same rules of physics apply ...

(via Minute Physics) This video covers the General theory of Relativity, developed by Albert Einstein, from basic simple levels (it's gravity, curved space) through to the concepts of how curved ...

‘I love the idea that this basic principle that Einstein told us about a long time ago is something you can see,’ CU Boulder astrophysicist says Scientists who study the cosmos have a favorite ...

In Newtonian physics, space and time had their independent identities, and nobody ever got them mixed up. It was with the theory of relativity, put together in the early 20th century, that talking ...

Susskind and Friedman follow their collaboration on Quantum Mechanics by probing the mathematical nitty-gritty of field theory and Einstein’s theory of special relativity in the third installment of ...

Albert Einstein’s mind reinvented space and time, foretelling a universe so bizarre and grand that it has challenged the limits of human imagination. An idea born in a Swiss patent office that evolved ...

It is one of history’s more irritatingly on-brand coincidences that Albert Einstein was born on Pi Day, as though the universe itself decided that if it was going to manufacture the patron saint of ...
