Atomic clocks rely on the resonant frequency of certain atoms to help in the measurement of the passage of time with extreme
accuracy. The energy change of an atom, produces a regular pulse, which can be measured, quantified and counted.
The current SI standard for the passage of one second is the time taken for a cesium - 33 atom to cycle 9,192,631,770 of these energy changes
This is one of the very many facts that you will learn from Mike Flynnin his book ''''Infinity in Your Pocket''''.
You will be surprised just how many facts you have forgotten since school. Mike puts over 3000 mathematics and science facts and formulae in a funny and well written book. Good for the general reader.
A great help for parents with kids at school.
