Ultra-low viscosity oils are becoming the norm for modern engines, especially smaller units prioritizing efficiency.

But there's more too it than that! We'll start by defining viscosity using Newton's Law of Viscosity, that describes the ...

If I then pour honey into the cup I will find that the cup drains very slowly. That is because honey's viscosity is large compared to other liquids' viscosities. If I fill the same cup with water, for ...

A small international team of nanotechnologists, engineers and physicists has developed a way to force laser light into becoming a supersolid. Their paper is published in the journal Nature. The ...
