There are many scientific units named after people, of which most were given their names a relatively long time ago (Watt, Newton, Celsius, etc).
I wonder if the scientists who "discovered" these units/laws usually get to know that their name is being used in such a way, i.e. if it is common to name the discovery while the person is still alive.
Of course I expect there to be many individual cases, but maybe there is some kind of standard or guideline when it comes to naming units. These are the cases I can think of:
- The scientist names the unit after himself. This rarely happens: What famous laws were named by their discoverer?
- The unit is given its name by someone else to honor the discoverer who is still alive.
- The unit is given its name by someone else (a long time) after the discoverer has died. Maybe to honor the person, or just because nobody could come up with a better name.
How is this usually handled, if there is any usual way at all?
