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, ...

Researchers at Penn, led by Physics and Astronomy professor Arnold Mathijssen, have discovered ways to achieve quality coffee extraction using fewer beans. Published in “Physics of Fluids,” 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, ...

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 ...

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

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

Cracked it: Fluid-based screen protectors need to absorb an impact as the system deforms. New research shows that simplifying the geometry of the system can be used to optimize the fluid. (Courtesy: ...

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 ...

Warm water pelagic snails don’t get much attention, but they certainly should. The snails move between ocean surface waters at night where they feed to their daytime sleeping quarters several hundred ...
