Physicists have spent the last 20 years pondering an apparent discrepancy between experimental results and theoretical ...

Its value describes the strength of the gravitational force acting on two masses separated by a given distance—or if you want to be relativistic about it, the amount a given mass curves space-time.

We may receive a commission on purchases made from links. It may look like a fancy ratchet, but a torque wrench's more elaborate mechanism adds a crucial feature: measurement. It replaces the ...

The bacterial flagellar motor is finally understood after 50 years. In its workings, columnist Natalie Wolchover finds the ...

Picture two materials sandwiched together. The boundary between them may appear flat, but, in reality, it is full of tiny bumps and dents. Suddenly, the materials are hit with a shockwave. If that ...

Condensed-matter physics is the study of substances in their solid state. This includes the investigation of both crystalline solids in which the atoms are positioned on a repeating three-dimensional ...

The Martin A. Fisher School of Physics enjoys an international reputation for excellence in research, and is one of the highest-ranked of its size in the country. The department offers rigorous ...

Abstract: In safety-critical control for permanent magnet synchronous motors (PMSMs), the overshoot after adding a spontaneous load is a crucial metric, leading to the unexpected motion of driving ...

Abstract: The spin-transfer torque magnetic tunneling junction (MTJ) technology may pave a way to a universal memory paradigm. MTJ devices with perpendicular magnetic anisotropy have the potential to ...

Magnetism is due to the magnetic fields around magnets. The fields can be investigated by looking at the effects of the forces they exert on other magnets and magnetic materials. Electromagnets - AQA ...
