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

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 ...

Interestingly, the researchers observed that when the doped metallic graphene samples were under the influence of THz light, ...

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

Kinematic viscometers have historically been of the gravity-driven glass capillary type, as specified in ASTM D446, and ...

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

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

Do you find the symbols on a container of motor oil baffling? Even if you understand most of them, you may not know the ...

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

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

Mechanical engineers have developed a system of artificial cilia capable of monitoring mucus conditions in human airways to better detect infection, airway obstruction, or the severity of diseases ...
