New research has unveiled a previously unacknowledged effect of Einstein’s relativity theory similar to time dialtion and ...

The theory of special relativity is rife with counterintuitive and surprising effects, the most famous of which are length ...

If I fill the same cup with water, for example, the cup will drain much more quickly. Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction of a moving fluid. A ...

Water and oil, and some other simple fluids, respond in the same way to all levels of shear stress. These are termed ...

It relates the diffusion coefficient (D) of a particle to its radius (r), the fluid's viscosity (η), and the absolute temperature (T). The equation is given by: The particles are spherical and much ...

I spent a high-octane weekend with Valvoline & Hendrick Motorsports learning how proprietary preparations can give you the ...

That means these engines usually need lower-viscosity oil—oil that is “thinner” and flows more easily to form a cushion of ...

Scientists on Wednesday said that they have successfully stirred a strange matter called a "supersolid" -- which is both rigid and fluid -- for the first time, providing direct proof of the dual ...

It has just the right mix of spreadability, stickiness, and friction to give pitchers a better grip on the ball.

In this work, we aim to explore how viscosity gradients affect the swimming efficiency of spheroidal squirmers in order to understand the role of swimming gait and shape on power expended and ...

Dear Tom, I own a 2008 Ford Taurus. The dealership told me that I should take my car to them to have the oil changed to insure that my warranty stays intact and that the proper oil and filter are ...
