Quantum mechanics looks at how things work at the atomic and subatomic levels, where particles behave in ways that seem ...

Join one of the most respected Department of Physics in the country and enjoy the flexibility, choice and challenge of our MPhys Physics degree. In Years 1 and 2, the course provides a foundation in ...

Quantum physics can generate truly random numbers — but, whether classical or quantum, random-number generators can be hard to trust. To demonstrate this, suppose you’re playing Yahtzee, a ...

Technology Engineering Here’s how to generate a truly random number with quantum physics CURBy is available online and free to use. By Andrew Paul Published Jun 12, 2025 2:01 PM EDT ...

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When high-energy light hits atoms, it knocks electrons loose.

The emitted light exhibits non-classical quantum properties, differing significantly from the light we encounter daily, which follows classical physics rules. To produce a much stronger photon signal, ...

The Best Classical Music of 2025, So Far Our critics picked nine performances that included star turns, new opera productions and the unveiling of a concert hall at the Frick Collection.

What if, just before we reach the bottom, we find out that reductionism fails? Big things are made of smaller things, and those smaller things are made of smaller things still. That’s ...

NIST performed one of the first complete experimental Bell tests in 2015, which firmly established that quantum mechanics is truly random. In 2018, NIST pioneered methods to use these Bell tests ...

The theory predicts that the combined effect of three focused laser pulses can alter virtual particles in vacuum, generating a fourth laser beam in a “light from darkness” process. “This is ...

What happens inside a black hole remains one of the greatest mysteries in physics. In 1965, Roger Penrose showed that under very general conditions, a gravitational collapse inevitably leads to a ...
