(Phys.org)—The speed of light, c, is one of the best-known constants, having a value of just under 300,000,000 meters per second in a vacuum. But in some alternative theories of cosmology, the speed ...

Internal-combustion engines run on the explosive power of burning gasoline; electric motors, by contrast, run on magnetic flux. There are several ways to create and manipulate flux, thereby ...

Researchers at Tampere University and their collaborators have shown how spectroscopic measurements can be made much faster. By correlating polarization to the colour of a pulsed laser, the team can ...

There are hundreds of millions of motor vehicles on U.S. roads, and tens of millions of people sharing them as drivers, pedestrians, bicyclists, skateboarders, and electric scooter users. It falls on ...

A low-cost, high-speed method for printing graphene inks using a conventional roll-to-roll printing process, like that used to print newspapers and crisp packets, could open up a wide range of ...

Researchers have shown how spectroscopic measurements can be made much faster. By correlating polarization to the color of a pulsed laser, the team can track changes in the spectrum of the light by ...
