Standard is the thing

Admin1: Physicists use experiments as false witness to establish a unit.

Doctor Gravytee: This is an old tradition in physics. It started with Coulomb's experiment, then Cavendish experiment, and then so called the discovery of the electron and the Millikan experiments are all definitions of new units by using experiments as false witness.

A1: If this is true physicists must be certified crooks.

Dr. G: It is not that simple. Take G. This is the so-called Newton's constant of universal gravity.

A1: Cavendish defined it.

Dr. G: No. Cavendish computed the mean density of the earth using Kepler's third law and called it an observation of Newton's law. In the 19th century hard core British Newtonists defined G in order to replace then prevalent Kepler's constant with G, the Newton's constant.

A1: Then when you see a constant in physics it is a definition?

Dr. G: Yes. You got it. Physicists make a definition. Fake an experiment and claim to have observed it. Then they enforce it as a constant of nature.

A1: Oh my God! Physicists are low life bottom dwellers! Low life snake oil salesmen and Shamans! I am so disillusioned.

Dr. G: Well, we are living in a world which is not atomic materialistic. So in a way, physicists prove that the world we live in is NOT atomic materialistic.

A1: Standard is the thing.

Dr. G: Yes. Exactly. There are no discontinuities in this world. It is all convention.

A1: This is so beautiful.

Dr. G: This is also so elegant.
