Superconductivity is a quantum physical state in which a metal is able to conduct electricity perfectly without any ...

What is quantum physics? Put simply ... some materials are superconductors that allow current without electrical resistance, and why we can’t get this trick to work at room temperature.

In this video, Jonny Nelson explains resistance. The current through a component depends on both the resistance of the component and the potential difference across the component.

How gravity causes a perfectly spherical ball to roll down an inclined plane is part of elementary school physics canon. But the world is messier than a textbook. Scientists have sought to ...

Resistance to azoles is spreading due to the use of a class of fungicides in agriculture, known as the DMIs. Resistance can double the risk of mortality from invasive aspergillosis. According to ...
