Learn how to calculate a satellite’s momentum and position under a constant force! 🛰️📐 This physics tutorial explains step by step how to model motion, apply Newton’s laws, and analyze orbital ...

A fundamental constant of the universe may not be so constant after all, according to a new study. Recent observations of distant galaxies suggest that the strength of the electromagnetic force the so ...

A crucial number that rules the universe goes big in a strange quantum material. The fine-structure constant is about 10 times its normal value in a type of material called quantum spin ice, ...

Images made with the W.M. Keck Observatory in Hawaii show how light from two distant galaxies is distorted into multiple images. UC Davis astronomers have made a new estimate of the Hubble Constant, ...

SANTA BARBARA, Calif. — The word “crisis” hung in the air from the very beginning of the meeting. In a room just steps from the ocean in Santa Barbara, astronomers and physicists shifted restlessly in ...

Do scientists need to re-examine the basic model of the universe? Using new measurements of cosmic distances, astronomers have refined their calculation of the Hubble Constant, a number that describes ...

Kwiat, D. (2026) Planck’s Constant—A Bridge to Charge and Entanglement. Journal of High Energy Physics, Gravitation and Cosmology, 12, 471-483. doi: 10.4236/jhepgc.2026.121026 .

Planck's constant reveals the quantum world's fundamental energy levels. It shows how light and matter exist in discrete units (quanta). This constant defines limits to our knowledge of particle ...

Electronics is really an applied branch of physics, so it isn’t surprising that if you are serious about your electronics, you probably know a little physics, too. If you’ve ever heard the term “fine ...

A team in Paris has made the most precise measurement yet of the fine-structure constant, killing hopes for a new force of nature. As fundamental constants go, the speed of light, c, enjoys all the ...
