Nobody does pasta quite like the Italians, as anyone who has tasted an authentic “pasta alla cacio e pepe” can attest. It’s a simple dish: just tonnarelli pasta, pecorino cheese, and pepper. But its ...

A group of fluid mechanics and physics researchers at the University of Pennsylvania have created what they believe is the best pour-over coffee technique. The key is using a goose-neck kettle and a ...

Using unconventional statistical mechanics to understand fluid dynamics, a professor helped solve a 150 year old physics problem of how turbulent fluids move through a pipe. In 1883 Osborne Reynolds ...

For decades scientists have been trying to solve Feynman's Sprinkler Problem: How does a sprinkler running in reverse work? Through a series of experiments, a team of mathematicians has figured out ...

Van Gogh's "The Starry Night" accurately depicts the energy distribution in turbulent flows. The painting's swirls follow Kolmogorov's law of turbulence, a key equation in physics. It also shows ...

Knots are everywhere—from tangled headphones to DNA strands packed inside viruses—but how an isolated filament can knot itself without collisions or external agitation has remained a longstanding ...

For decades scientists have been trying to solve Feynman's Sprinkler Problem: How does a sprinkler running in reverse—in which the water flows into the device rather than out of it—work? Through a ...

The image illustrates the experimental set-up: (a) Cut-away schematic of the floating sprinkler, (b) Flow control apparatus operating in suction mode, and (c) Flow imaging with a laser sheet ...
