OT: Happy Mole Day

[Rich S]

As a retired chemist, I must abide by the alchemist's creed and am required to wish all of you a happy and pleasant Mole Day with many more to come.

Thank you sir. Avogadro would be pleased.

For those who have forgotten their basic chemistry:

 

>Mole Day is a Nationally unofficially recognized day in celebration of

> of molecules. It is celebrated on Oct. 23rd (10,23) from 6.02 AM

> until 6.02 PM. Hence: 6.02x10^23 Avogadro's Number.

Dr Stein-

 

You must have to be a chemist to appreciate this 'holiday'. I just got home from work at the lab and even there, the biologists and microbiologists didn't have a proper appreciation of its significance.

 

One of the most vivid memories I have of undergraduate chem classes was one where a TA from another country was trying to explain the difference between molarity and molality with a very thick accent: he could not pronounce 'l' or 'r'. We kept him going in circles for 45min... Not very nice, maybe, but we did think it funny.

 

A long time ago...
