Here is the current picture of my coauthor, Joel Lewis. I remember him from many years ago when he was a graduate student at MIT. I am glad he kept his big smile.
Back to the subject matter. Joel Lewis made a comment on my recent post, thinking-outside-the-box ideas. He mentioned his two theorems:
The Big Point Theorem. Any three lines intersect at a point, provided that the point is big enough.
The Thick Line Theorem. Any three points lie on the same line, provided that the line is thick enough.
