(Nanowerk News) The equations that describe physical systems often assume that measurable features of the system — temperature or chemical potential, for example — can be known exactly. But the real ...

A suspended apparatus used to minimize friction during the experiment. The heavier brass cylinder and lighter ping-pong ball collide repeatedly against the transparent wall, reproducing 31 collisions ...

From the time she was a child, Anna-Sophia Boguraev has had her eye on space. When she was 4, she built a cardboard rocket ship. She asked a lot of questions, loved looking at the stars and was set on ...

Andrews Space & Technology (AS&T) successfully demonstrated the fundamental operating principles of a propulsion system that could dramatically affect interplanetary space travel, shortening round ...

The rules of statistical physics address the uncertainty about the state of a system that arises when that system interacts with its environment. But they've long missed another kind. In a new paper, ...

Each lemon can generate around 1.5V and, in 2021, a team coordinated by the Royal Society of Chemistry created a record-breaking giant lemon battery using nearly 3000 lemons, producing over 2300V.

We think everything is an accident of physics, but a long list of experiments suggests just the opposite. Amazingly, if you add us to the equation, you can explain some of the biggest puzzles of ...
