Today’s insights
I was going to write about some new insights here. I posted a picture. Then later added more pictures, to which I need a quick URL in order to refer to them elsewhere. So the new insights never came. But I think I still know what they were. Maybe I’ll write about them another time.

Today I had a large number of quite stunning insights. Later I might fill in, above, what some of them were, and also how it came that they came so many all at once. For the moment the first insight of today is: emptyness. If you are a mathematician, you can think of the empty set.
