Cloud of (Un)knowing

UnionStationRoof

It’s rare that my quotidian work matches my philosophic preoccupations closely, but sometimes it happens.  The Union Station in Toronto has a train shed roof (above) that is a landmark.  The supporting framework (truss) is distinctive, and was a patented design, also used in Hoboken, NJ.

Engineers like to work from plans, drawings, diagrams, like the one below.  Clean, precise, accurate.  Unambiguous…we think.  Problem was, there were no such drawings in existence.  To create them from hand measurements – a huge and expensive task.  Enter the laser scanner. Millions of points, all with (x,y,z) coordinates.  We call them point clouds.  Clouds of knowing (cf. Dionysius the Pseudo-Areopagite on the cloud), points of certainty.  This is there! Information, data, rich enough to make these precise drawings.

What is the grain of knowledge?  How granular is reality?  What is?

Zoom in far enough, and there is only empty space.  As it is inside us, and outside us.
