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?

Advancing the science of electron microscopy

Carnegie Mellon University professor Yoosuf Picard's research group develops and applies methods for using energetic beams -- electron, ion and photon beams -- in order to process and characterize materials at small length scales

NSF Science Now: Episode 55

In this week's episode, we learn how infants retain information; how loud noise can affect birds; the underpinnings of snake locomotion and, finally, the existence of a hitherto unknown ancient Native American population

3-D printing wirelessly connected objects

With computer-aided design models that a team of researchers is making available to the public, 3-D printing enthusiasts will be able to create objects out of commercially available plastics that can wirelessly communicate with other smart devices

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
