Researchers say they may have achieved Einstein's vision of a "unified field theory" that can unite two of nature's ...

instead of measuring deformation of a spring in some way it produces a force from an electromagnet to oppose that exerted by gravity on the mass to be measured, and quantifies how much electrical ...

In their quest to understand the fundamental forces of the universe, scientists have gotten stuck on gravity. While the other ...

The other three are gravity, electromagnetism and the "strong" force which holds together the particles of the atomic nucleus By S. B. Treiman Join Our Community of Science Lovers!

Fundamental forces, such as gravity, electromagnetism, and nuclear forces, form the fabric of our Universe. Magnetism, a ...

Isaac Newton - isn't he the guy who discovered gravity? Great! So, what's gravity? Aaaah, gravity is the force that makes objects fall towards the ground. And, without gravity, we'd all float!

That at least is the case with the strong nuclear force, one of four fundamental forces of nature (the others being electromagnetism, gravity and the weak nuclear force). The strong force holds ...

Magnets aren't attracted to copper, but when the two come together they can appear to defy gravity. Download the Magnetic Copper PDF (384 Kb). Adobe Acrobat is required. SAFETY: Neodymium magnets ...
