These are pieces I wrote for a blog I thought would be a kind of continuation of NOTES FROM THE MATHEMATICAL UNDERGROUND, the column I had for many years in the AMATYC Review. But, just as I never knew what the readership of the column was–––only once was there a letter to the editor, I never knew what the readership of the blog was–––there never was any comment–––and brought the blog to an end. Of course, that is the fate of most blogs.
