Re: All panduks are green

I have actually tried it. I drew one square Venn diagram, one Venn
diagram that looked like a circle and for the last one I used a green
marker. This method of visualization worked well, and I was very
pleased with my picture. But then i realized there was trouble. I
could not find the intersection of the square Venn and the circle
Venn. I stared at it for several hours and I still could not find it.
I could not visualize the intersection being inside the green zone, it
(the intersection just was not there.

So you don't understand the empty set?
