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 ...

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 ...

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 ...

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

A connection between fluids containing self-propelling particles and the fundamentals of quantum mechanics has been discovered by Benjamin Loewe, Anton Souslov and Paul Goldbart at the Georgia ...

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

The first ever camera footage from inside a centrifuge has revealed a new mystery in the physics of fluids. A centrifuge is a standard piece of laboratory equipment that spins fluid samples at high ...
