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 ...

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.

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 ...

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 ...

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 ...

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 ...

By using a low-viscosity silicone oil and fine-tuning the fabrication process, they've made the SlipChip more reliable for cell-based experiments and simpler for creating concentration gradients.

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.

In 2018, as an assistant professor, he had an insight: As seawater gets colder, it grows thicker. It’s basic physics — the density and viscosity of water molecules rises as the temperature drops.

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 ...
