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... wink ... 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... lol
I should add that there is a large "J" on the top.... J = Joule?

There is a ruin of an old Monastery here & there have been digs for a known stone age site but I doubt either dwellers would be capable of the equation... me thinks there must be a prankster afoot.,  if not, it really is a mind-boggling?
