In physics, the twentieth century started with the twin revolutions of relativity and quantum mechanics. Much of the second half of the century was devoted to the…

The theory of quantum mechanics has been hotly debated for over 100 years as our best description for the entire physical world. But the behaviour of small…
Although many examples can be found in the scientific literature dating back half a century, there is still no widespread acceptance that quantum mechanics – that baffling…
Human beings do not stand outside nature; we are a part of it. Ultimately we are made of particles, evolving and interacting according to the laws of…
Professor Susskind presents an explanation of what the Higgs mechanism is, and what it means to “give mass to particles.” He also explains what’s at stake for…
Simply put, this is cool physics and other sweet science. Here are some of the questions tackled in this series of short videos. Have you ever wondered…
Gravity. The stars in day. Thoughts. The human genome. Time. Atoms. So much of what really matters in the world is impossible to see. Did you know…
Space and time are two of the universe’s most fundamental elements. Relativity combines these two into the unified notion of space-time, but twistor theory goes beyond this…
Apart from Einstein, Paul Dirac was probably the greatest theoretical physicist of the 20th century. Dirac, co-inventor of quantum mechanics, is now best known for conceiving of…
An introduction to Einstein’s Theory for a lay audience. The only preparation needed is an open mind. Albert Einstein described Relativity as a “popular explosion” of his…
The strong, weak, and electromagnetic interactions all have consistent, relativistic and quantum mechanical descriptions in terms of pointlike particles, but Einstein’s theory of gravitation has long resisted…
