Conversion of Units: Unit conversion is a multi-step process that involves identifying the starting and desired units, finding the appropriate conversion factors, and strategically using ...

Despite its many successes, physicists are still struggling to nail down a coherent interpretation of quantum mechanics, as it best represents “reality”. Jim Baggott explores the arguments first put ...

A new measurement in quantum electrodynamics – an extension of quantum mechanics – is 10 times more precise than any recent measurements. Quantum electrodynamics, or QED, is one of the most successful ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. In the last few weeks I've been working on a slightly more formal ...

Class 11 Physics Notes for Chapter 2 Units and Measurements (Class 11 Physics NCERT textbook) are available here. This part is the continuation of Part I, the topics covered in this part are: Order of ...

Incorporated into every aspect of everyday life, the neutron is a fundamental particle of nature. Now, a research collaboration led by Los Alamos National Laboratory has improved the precision of free ...

Ideal system: A strontium ion trapped in an electric field. The measurement on the ion lasts only a millionth of a second. (Courtesy: F Pokorny et al., Stockholm University) Anyone familiar with ...

A subatomic particle called the W boson may be heavier than expected, a surprising finding that might lead to a shake-up of physics' grand model of how the world works on the microscale. When you ...

The most exciting possible avenue for physics beyond the standard model of particle physics has been, for years, the discrepancy in the anomalous magnetic moment of the muon. After refinement in the ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...
