Welcome! This weblog was created by three Cornell mathematicians to talk about whatever math was on our minds. The closest approximation to a unifying theme is Geometry, in that geometry is an integral part of the math we do.
Matt Noonan is a graduate student at Cornell. He enjoys differential geometry and solving things by making a boat, and then not caring about the problem because he has a boat.
A note on the categories:
We employ two kinds of category: by author and by difficulty level. The difficulty levels are there as a crude method of indicating what level we presume, as well as providing the option of generating a version of this blog which omits entries aimed above your head. The levels are:
High School: For a broad audience, presuming little or nothing besides some basic mathematical maturity.
Undergraduate: Typically for undergraduates who have taken some introductory courses to ‘math after calculus’. Might require a semester of algebra, analysis, topology or geometry.
Basic Grad Student: This is meant to be the kind of topic one could give a graduate student colloquium on. These shouldn’t assume anything not found in the first two years of graduate study.
Anything else won’t have a difficulty category, and might consist of advanced topics and research-level material. Hopefully, we will try to make known in the first few paragraphs who should be able to read these.
A note on the tags:
As far as our tags go, we try to tag posts with the appropriate arxiv subject. If enough math blogs do this, then those tags should be able to generate journal-style compilations of posts on a topic.
