If you’ve ever whacked the bottom of a ketchup bottle to get that tasty tomato goop flowing, you’ve put some serious physics to work. Ketchup is a non-Newtonian fluid. So are toothpaste, yogurt, ...

Rheology, high-speed imaging, and velocimetry combined to characterize how some roller-based nozzles perform so well with non ...

Gears have been around for thousands of years, with the first records dating back to 3000 BC. While they have advanced over ...

Fundamental constants: a minimum value of viscosity has been calculated by Kostya Trachenko and Vadim Brazhkin (Courtesy: iStock/3quarks). Viscosity is an everyday phenomenon recognizable in the ...

Marathoners queuing up for a big race tend to go with the flow, surging toward the start line like a fluid. Using footage of runners moving in groups toward the start of the Chicago Marathon, ...

Imagine a "smart fluid" whose internal structure can be rearranged just by changing temperature. In a new study published in Matter, researchers report a way to overcome a long-standing limitation in ...

The currents of the oceans, the roiling surface of the sun, and the clouds of smoke billowing off a forest fire—all are ...

In a significant advance for semiconductor manufacturing, mechanical engineers created a simulation that makes it easier to choose environmentally friendly water jet and underwater ultrasound ...

A physicist proposes that the universe is not empty space, but is a viscous fluid, fueling the expansion and contraction we see.
