Aug 9th - World Indigenous People, Books and 6.02x10^23

 Canada has it's Indigenous People's Day on June 21, but in 2015 the UN created the "International Day of the World's Indigenous Peoples" for August 9th.


One way that you can learn more about the world's Indigenous peoples by reading books - and as luck would have it, it's also Book Lovers Day.


Another thing you can read in a book is some Chemistry, and well, I'm a chemical nerd.  One of my favourite things in chemistry is weird facts - like Avagadro's number:  NA = 6.02x1023.  Essentially, the number of 'things' in 1 gram of it or one 'mole'.

You can have a dozen of something - 12 of it.  You can have a baker's dozen - 13 of it.  You can have a pair of things - 2.  You can have a gross - (12 dozen = 144).

You can also have one mole of it, or an Avagadro's number. Have 602,214,141,070,409,084,099,072 of something and you can say you have one mole of it.

The guy they named the number after, was Amedeo Avogadro - who came up with Avagadro's law, saying that for 'ideal gases' there is a constant relation between their volume, temperature and pressure; which eventually led to the ideal gas law - the infamous PV=nRT.

Amedeo would have been 245 years old.



yeah, chemistry earns a second pic... never know which one makes the better virtual background
