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 ...

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.

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 ... In the case of non-Newtonian ...

In runny, low-viscosity liquids, the bursting process is over in a matter of milliseconds ... “It is through a delicate interplay of capillary, viscous and inertial forces that wrinkles develop,” he ...

Part of the problem lies within the physics of the condiment itself ... Newtonian fluids retain their viscosity — or resistance to flow — regardless of the amount of force you put on them.

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 ...

These are termed Newtonian fluids, and their viscosity is constant for all stresses although it will vary with temperature. ... Neutron stars are the remnants of old stars that have run out of ...
