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 ...

Non-Newtonian fluid flows deviate from classical Newtonian behaviour by exhibiting viscosities that vary under different shear conditions. In these fluids the viscosity is not constant but responds ...

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 ...
