Scientists can put two uncharged metal plates close together in a vacuum, and 'voila!' -- they will attract each other. In 1948, Dutch theoretical physicist Hendrick Casimir first predicted an ...

Vesselin Dimitrov’s proof of the Schinzel-Zassenhaus conjecture quantifies the way special values of polynomials push each other apart. In the physical world, objects often push each other apart in an ...

RIVERSIDE, Calif. – The Casimir force, also known as the Casimir effect, is typified by the small attractive force that acts between two close parallel uncharged conducting plates. Today, this force ...

Limited wavelengths: the Casimir effect arises because virtual photons at certain wavelengths cannot emerge in a gap between two plates (Courtesy: iStock/4X-image) Physicists in the US have worked out ...

Researchers have discovered a "repulsive" light force that can be used to control components on silicon microchips, meaning future nanodevices could be controlled by light rather than electricity. A ...

CAMBRIDGE, Mass. – January 7, 2008 – Researchers from Harvard University and the National Institutes of Health (NIH) have measured, for the first time, a repulsive quantum mechanical force that could ...

All fundamental forces operating on astronomical scales exhibit a decrease in strength with increasing distance. A hypothetical force, decreasing with distance slower than the inverse square law, ...
