Researchers at OIST built a graphite disk that levitates and spins for hours in a vacuum, showing how perfect magnetic ...

A major milestone has been achieved by NASA and SpaceX. The organizations involved in space exploration and aeronautics research have successfully elevated the orbit of the International Space Station ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

We tested 16 models from top brands, including Giro, Specialized, Lazer, and more, to find the best road bike helmets.

With a clever design, researchers have solved eddy-current damping in macroscopic levitating systems, paving the way for a ...

Abstract: Electromagnetic parameters of electromagnetic structural materials (EMSMs) are the basic parameters used to optimize the reflection and transmission characteristics of materials. Unlike ...

The two keys to Edwin Hubble's breakthrough discovery were forged by others in the 1910s. The first key, the period-luminosity scale discovered by Henrietta Leavitt, allowed astronomers to calculate ...

Abstract: Global navigation satellite system (GNSS) receivers operating in urban environments frequently encounter multipath interference, a phenomenon wherein direct and reflected signals interact.
