When the world's expert on pygmy mammoths asks you a question about ketchup, you have to find the answer. The context was the article I wrote last week about non-Newtonian fluids, where researchers at ...

One of these is not like the others: honey, water, ketchup, and blood. The answer? Water, because the other three are all non-Newtonian fluid. When Isaac Newton first defined the properties of an ...

Quicksand and other non-Newtonian fluids share properties with both liquids and solids. Non-Newtonian fluids consist of tiny grains suspended in liquid, with the appearance of a solid or gel. Stand on ...

If you mix cornstarch and water in the right proportions, you get “oobleck”: something that seems not-quite-liquid but also not-quite-solid. Oobleck flows and settles like a liquid when untouched, but ...

Dilatants are a class of non-Newtonian fluids characterized by their ability to transition from a fluid state to a near-solid state under shear stress due to a high concentration of solid particles ...

Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...

In the most basic of terms, rheology can be considered the study of flow behavior in materials, whether solid, liquid, or gas. Rheology recognizes that certain solids respond with plastic flow in ...
