Topic: Quirk of nature
Glad to see the forum is back up & running.
My wife found these 2 pebbles in a river bed of dark coloured stones while out with the dogs.
With a little bit of scrutiny + imagination... ... a mathematical equation is apparent... electrical resistance/capacitance/flux etc., strange quirk of natural rubbing/collisions or someone deliberately etching the equation onto the pebble??
'I' is the symbol for 'Ampere/current', 'X', '172', 'N/L'
I entered the equation into Google & was stunned when it showed an answer? 172000m-2 kg s-2A
The other pebble was as surprised as I was...
I should add that there is a large "J" on the top.... J = Joule?
