Imagine a gas is trapped inside a container which has a fixed size (its volume cannot change). Gas pressure is caused by the collisions of the gas particles with the inside of the container as ...

Scientists have calculated the Earth to be 4.54 billion years old, with an uncertainty of 50 million years on either side.

But if you watch [tomtektest’s] recent video, you’ll learn they are really Kelvin probes. Kelvin probes are a special type of probe for making accurate resistance measurements using four wires ...
