Hi Jonathan – what a great post! I’m especially struck by your call for collaboration outside Mathematics departments – the broadening of perspective that comes from working with folks in other disciplines can be […]

Hey jojo – This is my favorite thing I’ve stumbled across on the Commons today. Really nice work!

Marcos! It seems you have a certain amount of freedom in choosing the content in your “fundamentals”-type courses, which I envy – ours are more-or-less proscribed by the department, via a detailed syllabus. But […]

What resonates for me is the journey of discovery (and wonder!) that comes from learning about normal distribution, the CLT, and its corollaries. This is one of my recent favorite mathematical ideas, and […]

This is such a great post. The question of “what to do about math education” is maybe one of the central themes of this blog (and at CUNY, and in national education), and I often feel at a loss to make sense of […]

Sandra – welcome to the CUNYMath Blog! Great post. The practice of mathematics — wrestling with the problems! — is so important, and it’s constantly amazing to me how few students will do it without some […]

Brian – thanks for the shout-out to CUNYMath, and I echo your sentiments about Hunter’s post — he’s raising the bar for us! I think you might also appreciate his latest post, Existence. Let me quote:

“We can […]

Okay, I finished it. Hunter, thank you for this beautiful and thought provoking post, and for raising the bar for the CUNYMath Blog. I love your list of questions at the end, and I echo the sentiments of Brian […]

Hunter, I must admit I made it just about halfway through your latest post before being distracted by your link to the page on “roots” (http://math.ucr.edu/home/baez/roots/), and, surfacing from this page a half […]

Great question — it seems quite natural to extend to higher dimensions. The n=3 case seems like such an obvious one to tackle — I’m surprised it isn’t explored in the way that 2D tilings are. I know there is a […]

Great post — these examples are distressing! This resonates with discussions I’ve been having lately with pedagogy-minded folk around my office. What are our students meant to think of all this? How the heck […]

Hi Sue — thanks for the comment! Yes, I think your criticisms of Khan are quite valid — and maybe (for me) the take-away is that they are NOT a replacement for good teaching, and they must be used carefully to […]
