with Anu Gargchirality
PRONUNCIATION:
MEANING:
noun: The property of not being superimposable on its mirror image: dissymmetry.
ETYMOLOGY:
Coined by physicist, engineer, and mathematician William Thomson, Baron
Kelvin, also known as Lord Kelvin (1824-1907). From Greek cheir (hand).
Ultimately from the Indo-European root ghes- (hand), which also gave us
cheiromancy/chiromancy (palmistry), surgeon (literally, one who works
with hands), and enchiridion
(handbook). Earliest documented use: 1894.
USAGE:
“Hands, feet, and shoes, [Richard Dawkins] explains, have chirality, i.e.,
‘there’s a left one and a right one and you can’t rotate either to
make the other’. Socks, on the other hand, are interchangeable. So, he
suggests, embrace the diversity and wear your odd socks with pride.” Rose Wild; The Science Professor Needs to Put a Sock in It; The Times; (London, UK); May 28, 2016. A THOUGHT FOR TODAY:
The rightness of a thing isn't determined by the amount of courage it
takes. -Mary Renault, novelist (4 Sep 1905-1983)
