For decades, physicists have studied the way an electron ought to bind to a proton, the simplest atomic system. The fascinating patterns of hydrogen orbitals that form at different energy levels are ...

The wavefunction of a particle represents the probability distribution of its position in space. Measuring the particle's position, however, involves the projection of its wavefunction onto one of the ...

The poet Blake wrote that you can see a world in a grain of sand. But even better, you can see a universe in an atom!

Although tiny, a proton takes up a finite amount of space, enough to fit three quarks, a host of virtual particles, and their associated gluons. The size of a proton’s radius is determined by these ...

Scientists have synthesized a compound that absorbs near-infrared light to produce hydrogen from water. The compound contains three ruthenium atoms connected by an organic molecule. The absorbed light ...

In a significant step for one of Southern California’s growing private space startups, Rocket Lab said its Electron rocket made it to space in its first test flight Wednesday night, but did not reach ...
