Step inside the strange world of a superfluid, a liquid that can flow endlessly without friction, defying the common-sense ...

You’re on the street and you’re alone. Spanning the horizon, you see the sun cresting and one glorious corner after another. Some are slow, others are fast, with a few nice straights in between. Tire ...

For nearly two centuries, textbooks blamed icy spills on pressure and friction, but new simulations tell another story. The ...

The machine doesn’t care what it’s making—only that it’s making it fast. Frictionless systems optimize output. But meaning, memory, and margin live in the mess it leaves behind. The great smoothing is ...

Why do some people create friction in their workplaces? According to Bob Sutton, a professor of organisational behaviour at Stanford Graduate School of Business, some folks are oblivious when their ...

It's perhaps the second week of your introductory physics course. Your instructor starts talking about friction and writes the following two formulas on the board. Then there is probably some sort of ...

• The process is completed in a few seconds with very high reproducibility - an essential requirement for a mass production industry. Now, a new variant from the same stable of friction processes, ...

A pleural friction rub is a raspy breathing sound caused by inflammation of the tissues around your lungs. The sound is usually “grating” or “creaky.” It’s also been compared to the sound of walking ...

Friction burns — aka rug burns — can happen when you fall on rough surfaces like asphalt and grass. You can care for minor burns at home by applying cool compresses and taking OTC pain medicine.
