Occasional obeisance...


Today, in many parts of the Anglosphere, is Mole Day...not quite what you think: not the mouldywarp (dirt tosser**), not the common intradermal nevus, not the spy and not the breakwater (amongst other things). This mole day is one of those "science" days based on the written date (e.g. Pi Day on March 14 in US month/day format is 3/14) and on Mole Day the time comes into play too: on October 23 from 6:02 in the morning; making the date 6:02 10/23; the time and date making Avogadro's number, which is approximately 6.02×1023, defining the number of particles (atoms or molecules) in one mole of substance...still with me? The name 'mole' from the German unit Mol, (probably from Molek├╝l) was coined by the German chemist Wilhelm Ostwald. In the USA this makes up part of National Chemistry Week.
"Everything you hear, see, smell, taste, and touch involves chemistry and chemicals (matter). And hearing, seeing, tasting, and touching all involve intricate series of chemical reactions and interactions in your body. With such an enormous range of topics, it is essential to know about chemistry at some level to understand the world around us."
Chemistry is probably one of the best subjects to learn - it was certainly one of my favourites - because most of the time it's all about DOING stuff.

** Off topic but did you know the name given to a group of the blind, bug-eating dirt tossers is a labour? LOL!
