- To correct a length you need to calculate the difference in temperature multiplied by the product of the length and the expansion coefficient.
- A number of factors need to be taken into account when considering sources for calibrating radiation thermometers.
- If you look at several atomic clocks all set to the same time you'll find that they still agree within ten millionths of a second after a week.
- Buoyancy is the upward force exerted on an object when it is immersed, partially or fully, in a fluid - and strictly where the fluid is subjected to a gravitational force but is not in free fall.
