Rota was my favorite professor. This is a collection of fairly random writings of his. There are short biographies of mathematicians that Rota knew, some writings on Phenomenology that are well beyond my understanding, and musings on what Mathematics is and how its practitioners actually work.

The biographies seem to be somewhere between gossipy and irreverent and flat-out mean. Rota seems to be trying to show that a great mathematician needn't be a good person. Perhaps unintentionally, he seems to be underscoring the point by being unpleasant himself.

The Phenomenology is well outside my ken. I tried to make sense of it, but I'm failing on basic vocabulary. I wish I'd read the afterword first. It warns that almost nobody understands the distinctions Rota is making in these passages.

The musings on Mathematics were very interesting. Rota hits the nail on the head a number of times.
