Why do certain surfaces behave very differently from what theoretical calculations suggest? Scientists long assumed that the ...

Using one of the world's most precise atomic clocks, physicists have shown that time runs a tiny bit slower if you change your height above the Earth's surface by a minuscule 0.008 inch (0.2 ...

A new experiment involving a network of entangled atomic clocks could finally help us test how quantum mechanics fits with general relativity. Quantum mechanics is our best understanding of the ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a ...

Nucleons, which include protons and neutrons, are the composite particles that make up atomic nuclei. While these particles have been widely studied in the past, their internal structure has not yet ...

An electron collides with a deformed nucleus and produces a single vector meson (J/Psi). The green cone indicates that the J/Psi production carries information about the size and shape of the nucleus, ...

Optical atomic clocks are the most accurate measuring instruments ever built and are becoming key tools for basic and applied research, for example to test the constancy of natural constants or for ...

For nearly 50 years, physicists have dreamed of the secrets they could unlock by raising the energy state of an atom's nucleus using a laser. The achievement would allow today's atomic clocks to be ...

Scientists long assumed that the aluminum oxide surface should be highly reactive and capable of splitting water molecules.
