University of Chicago physicists working in the nascent field of experimental vortex dynamics have, with unexpected help from a Sharpie marker, achieved the first measurements of an elusive but ...

What if a material that looks solid could actually flow… over nearly a century? Launched in 1927 by an Australian professor to illustrate viscosity, an experiment of disarming simplicity has become a ...

Is pitch a liquid or a solid? It turns out that while it appears to be a solid at room temperature, it actually flows like a liquid ... a very, very viscous liquid. Why is this interesting? One of the ...

Start your week with this mind-blowing demonstration of laminar flow, courtesy of the University of New Mexico’s Physics Department. The apparatus, called a “Couette Cell,” was developed by John ...

They coil. They swing. They fold. They meander. Streams of honey, oil and other viscous fluids can do things that physicists still don't fully understand If you like honey on your toast at breakfast, ...
