Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...
Friction usually announces itself through contact. A chair scraping across a floor, a tire gripping asphalt, a hand sliding ...
Friction is hard to predict and control, especially since surfaces that come in contact are rarely perfectly flat. New experiments demonstrate that the amount of friction between two silicon surfaces, ...
At a busy street crossing, people wait for the signal to change. When one person steps out first, others soon follow. Scientists in Amsterdam have found that this same kind of behavior happens at a ...
SANTA BARBARA, Calif. — To evade friction, try taking a quantum shortcut. Two teams of physicists are building tiny machines designed to operate with the maximum possible efficiency. According to ...
Curling is a thrilling sport filled with strategy, skill, sweeping, surprise and science! Curling is a mesmerizing sport filled with strategy, skill, surprise, a lot of yelling, and science—yes ...
When tectonic plates move, they rarely do so smoothly. Sometimes they slide almost imperceptibly; at other times, stress is ...
Researchers found friction can occur without contact, driven by magnetic dynamics, and does not always increase with load. The effect could enable controllable, wear-free technologies.
Wear has major impacts on everything from the bearing of a wind power plant to an artificial hip joint. However, the exact cause of wear is still unclear. Scientists now show that the effect occurs at ...
The best part about living in Vermont is that we get to experience all of the seasons. Sometimes cool weather appears out of nowhere and we don’t have the proper attire so we rub our hands together to ...
Memory fault: friction study could provide new insights into why earthquakes happen. (Courtesy: iStock/allanswort) Experiments by Sam Dillavou and Shmuel Rubinstein at Harvard University have, for the ...
