This morning on BBC Radio 4, the mathematician Roger Penrose, physicist Basil Hiley, and philosopher Simon Saunders had a lively discussion about the “measurement problem in physics” with broadcaster ...

Cracking a 15 year physics mystery, researchers measured the precise size of a proton. In A Nutshell A team in Germany used an unprecedentedly precise laser measurement of hydrogen to pin down the ...

During the mid- to late-twentieth century, quantum physicists picked apart the unified theory of physics that Einstein’s theory of relativity offered. The physics of the large was governed by gravity, ...

Laser power measurement may look simple, but fascinating physics is working behind the scenes. Discover the insights behind ...

(via PBS Space Time) The mystery of what happens when we go from a superposition to a definite state is known as the Measurement Problem, and it’s arguably the most mysterious outstanding problem in ...

One of the most striking features of quantum physics is that certain properties cannot be measured at the same time. Every measurement may inevitably affect the object's physical state being ...

To operate fusion systems safely and reliably, scientists need to monitor plasma fuel conditions and measure properties like ...

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

Uncertainty affects the accuracy with which measurements can be made in quantum physics. To reduce this uncertainty, physicists have learned to "squeeze" certain measurements. Researchers are now ...

A new measurement of a fundamental particle called the W boson appears to defy the standard model of particle physics, our current understanding of how the basic building blocks of the universe ...
