Electromagnetic momentum and optical forces have emerged as pivotal concepts in modern optical science, bridging fundamental physics and advanced technological applications. At its core, ...

There's a beautiful, elegant idea that's out there in physics: that everything we see, perceive, and interact with in this Universe is just a different manifestation of the same fundamental force in ...

Nuclear physics is a forbidding subject, even for trained physicists. To understand current news and discussion about nuclear science and technology, some background knowledge is required. The high ...

Add Yahoo as a preferred source to see more of our stories on Google. In the very early, very hot moments of the universe, the electromagnetic and weak nuclear forces were actually the same force—the ...

The electromagnetic force has gotten a little stronger, gravity a little weaker, and the size of the smallest "quantum" of energy is now known a little better. NIST has posted the latest ...

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.

One hundred and fifty years ago this month, the 30-year-old James Clerk Maxwell published the first part of an extraordinary document: On Physical Lines of Force, a paper on the mathematical physics ...

One hundred years ago, Albert Einstein had only just published his revolutionary new theory of gravity, atomic nuclei were entirely mysterious, and quantum “theory” was a tissue of guesswork.

Fundamental interactions, also known as fundamental forces, are the interactions in physical systems that do not appear to be reducible to more basic interactions. Much like the periodic table of ...
