Physics

Physics is the science of matter, energy, space and time. It looks both inward and outward, from the smallest subatomic particle to the vastness of the universe—and yet it is also intensely practical. Physics begins with the everyday physical world around us—the blue of the sky, the colors of the rainbow, the fall of an apple, the motions of the moon. What's happening here? Why do things work this way?

Building a quantum computer with atomic ions

Two independent teams of scientists, including one from the Joint Quantum Institute, have used more than 50 interacting atomic qubits to mimic magnetic quantum matter, surpassing the complexity of previous demonstrations

How mosquitoes get away

Scientists have found the key to mosquitoes' stealth takeoffs: They barely push off when making a fast getaway, but instead rely on strong and rapid wing beats to quickly get aloft without anyone noticing

NSF Science Now: Episode 53

In this week's episode, we discover a new species of titanosaurian dinosaur and how airline boarding procedures might be making you sick; we explore a compact mass spectrometer for use in the field; and finally, we learn how vertebrate tails actually provide greater speed

Ripples of gravity, flashes of light

On Aug. 17, 2017, the Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo detected, for the first time, gravitational waves from the collision of two neutron stars
