The gyroscopes give Hubble a reference direction...

Put the egg down on a smooth, hard surface and set it spinning. ...[W]hen you stopped the raw egg, you only stopped the shell. The liquid never stopped swirling... so... the shell started rotating again... dragged around by its insides. ...It is a principle of physics that objects continue the same... movement unless you push or pull on them. ...[C]onservation of angular momentum.

Learning the science of the everyday is a direct route to the... knowledge... every citizen needs...
