Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete.

For example, amateur space jumper Nick ... down into the atmosphere with enough lift to reduce frictional heat, while also reducing the G-force on the pilot. Eustace has spent enough time thinking ...

Between 2025 and 2033, the market for tokenized real-world assets is expected to achieve a compound annual growth rate (CAGR) ...

In this example, the pressure angle is 20 degrees as shown by ... Self-locking results from the small lead angle of the worm threads, which produces high frictional forces at contact. A multi-start ...

The downdraught may be further enhanced by the frictional drag of the precipitation and by strong ... amounts of rain in repeated downpours over the same area. These last two examples are unlikely to ...

Steely Dan is more than just a band—they’re a musical phenomenon. Discover how Donald Fagen and Walter Becker’s innovative ...

An international team of researchers has developed a new method for parameterizing machine-learning interatomic potentials (MLIP) to simulate magnetic materials, making the prediction of their ...

Humans are beautifully, gorgeously complex, and that means communicating with them is perennially challenging.

Developers are creating ways to improve diesel emissions and fuel economy while also meeting alt-fuel equipment needs.
