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?

Electromagnets unwire the framework of small, foldable robots

A team of researchers at the Wyss Institute for Biologically Inspired Engineering and the John A. Paulson School of Engineering and Applied Sciences (SEAS) at Harvard University has created battery-free folding robots that are capable of complex, repeatable movements powered and controlled through a wireless magnetic field

Sonic cyberattacks on MEMS accelerometers

New research at the University of Michigan calls into question the longstanding computer science tenet that software can automatically trust hardware sensors, which feed autonomous systems with fundamental data they need to make decisions
