Find X

Man, I can hardly spell when I get up on the whiteboard in a big mediation at the best of times - let alone do calculus.

But this week, after I offered to track on the whiteboard a geotech's explanation of soil density around some suspect marina piles, I was asked to 'find X' on his diagram - sure, I saw his lips move, but all I heard was blah blah blah.

But I am pleased to report dear reader, I was equal to the task.
