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 ...

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 ...

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 ...

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 ...

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 ...

Melvyn Bragg and guests discuss one of the deepest problems in contemporary physics. It’s called the measurement problem and it emerged from the flurry of activity in the early 20th century that gave ...

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 ...

A team used a first-of-its-kind technique to measure the expansion rate of the Universe, providing insight that could help more accurately determine the Universe's age and help physicists and ...

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 ...
