An international team of researchers has systematically measured the β-decay half-lives of 40 nuclei near calcium-54, ...

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, ...

Nanomechanical systems developed at TU Wien have now reached a level of precision and miniaturization that will allow them to ...

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 ...

“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral ...

We know how to derive most fundamental constants from conditions of the universe, models This is an accurate description of physics as a whole, but wildly untrue in particle physics. There are 25 ...

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 ...

Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

Recently in my physics lab, students were having trouble with the difference between mass and weight. I had ready answers---it’s a topic I’ve gone over hundreds of times. But after I explained that ...
