Note that viscosity—how resistant a fluid is to flow ... and has been brought back from there by the fluid physics people. Apparently, optics people don't talk directly to fluid people.

In physics, a fluid is a substance with zero resistance to shear force, meaning any applied stress causes persistent deformation. Underlying this behavior are two connected concepts: viscosity and ...

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 ... In the case of non-Newtonian fluids, the viscosity also changes ...

Essential for life: this illustration shows how fundamental constants of nature set the fundamental lower limit for liquid viscosity. (Courtesy ... physical constants in the context of particle ...

About 8 ml of blood with a viscosity of 7 centipoises (cp ... believes there is a “tremendous thirst” in the medical community for this kind of physics-based innovation. “I believe the work has raised ...

that substance and others similar to it could be the most-perfect fluids in existence because they have ultra-low viscosity, or resistance to flow, said Dam Thanh Son, an associate physics ...
