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 ...

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 ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

Microswimmers: Studying how bacteria swim in complex fluids provides insight into how the micro-organisms move through different environments, such as inside the human body. (Courtesy: Cheng Research ...

Scientists investigate the strange behavior of viscoelastic fluids in a series of specially designed experiments. Viscoelastic fluids are everywhere, whether racing through your veins or through 1,300 ...

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 ...

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 ...
