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

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 ...

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 ...

Friction plays a key role in how ruptures unzip faults in the Earth’s crust and release waves that cause destructive shaking. Yet dynamic friction evolution is one of the biggest uncertainties in ...

Friction is responsible for about twenty percent of the world energy consumption. The main reason for this is that frictional forces slow down the motion of surfaces in contact: think of the moving ...

In a recent stunt, a Ford crew hitched an all-electric F-150 pickup truck to a freight train filled with 42 more F-150s. Then a driver hit the throttle, and the pickup truck towed the 1.3 ...

You should not use automotive oil in a motorcycle engine. Here’s what can go wrong, from reduced lubrication to accelerated ...

Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

Learn about friction cost to make better informed decisions: its implications in investments and loans, and how it helps assess the true cost of financial transactions.

In the modern enterprise, the IT department is often caught in a “maintenance trap.” Research suggests that IT teams spend up to 70% of their time simply keeping existing systems running—patching ...

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.
