Almost all measurements of motion in astronomy make use of a law of physics called the Doppler effect. This change in the wavelength (or frequency, color, or pitch) of a wave emitted by a moving ...

Many natural processes, ranging from magnetism to chemical reactions, entail the movement and rotation of particles at very ...

Everyone loves perpetual motion machines. They are a representation of the highest level of creativity in finding loopholes in the laws of physics. Let's take a look at this one. What is a perpetual ...

It has been one hundred years since the publication of Einstein's general theory of relativity in May 1916. In a paper recently published in EPJ Plus, Norwegian physicist Øyvind Grøn from the Oslo and ...

The non-thermal nature of self-propelling colloids offers new insights into non-equilibrium physics. The central mathematical model to describe their trajectories is active Brownian motion, where a ...

Construction of nano-devices that can generate controllable unidirectional rotation is an important part of nanotechnology. Here, we design a nano-turbine composed of carbon nanotube and graphene ...
