I congratulate everyone on the day of the chemist!
And we are all chemists a little or a lot.
The word Chemist in Russia has two meanings. Firstly, it is a chemistry teacher at school or university (химик is a man, химичка is a woman), a chemical worker and a scientist. Secondly, a "chemist" is a person who does a little "chemistry". Example. I have to pay tax, but naturally I don’t want to do it. I believe that the state is spending my money incorrectly. I will "cheat" (похимичу - do chemistry) a little and pay less than required by law.
Chemist's Day, October 23rd, is also my birthday. Today I turned exactly 73 years old. It is easy to remember - in SI there are 7 basic units of measurement, and in the CGS - three.
PS By the way, the word mol (моль) in Russian is both the amount of a substance and an insect that flies in the house and can eat a fur coat. This insect does not like chemistry - naphthalene.
PPS But I'm a real chemist. See for example
