What? No “Decolonize Catan” bumper stickers for sale? Shame on you, Internet!
I’m disappointed to learn that “hypergamy” refers to nothing more interesting than what used to be called “gold-digging”. I was hoping it referred to something more genuinely mind-bending, like being married to uncountably many people along uncountably many timelines.
I want to support public media in underserved areas of the U.S. Is there a fund that will spend my donation where it will do the most good? nytimes.com/2025/07/16/opi…
Learn about the world of q-deformed numbers, in which 1.1 (aka 11/10), 1.01, 1.001, ... converge to 1 but .9, .99, .999, ... converge to 1's "evil twin", in my latest Mathematical Enchantments essay: mathenchant.wordpress.com/2025/07/17/whe…

When you see things that aren't there it's called hallucination. But when you see the *right* things that aren't there it's called mathematics. For a fun example read my new Mathematical Enchantments essay "Math and the Museum": mathenchant.wordpress.com/2025/05/21/mat…

Is 1 prime? You don't have to care about the answer, but you should care about the history of the question and what it teaches us about the nature of mathematics. See my latest Mathematical Enchantments essay "Is 1 Prime, and Does It Matter?" mathenchant.wordpress.com/2025/04/21/is-…
#YouMayBeAMathematicianIf it bothers you that unlocking your car or starting the engine involves turning your key in a *clockwise* direction when everyone knows the positive direction is *counterclockwise*.
If God wills that I win the lottery, it would be impious for me not to do my part by buying one. On the other hand, if God does not so will (or if God — God forbid! — does not exist), then I lose little in buying one. Therefore I should buy a ticket.
Read about how the Greek letter pi came close to being associated with the number we now call 2 pi in this month's Mathematical Enchantments essay "How Pi Almost Wasn't". mathenchant.wordpress.com/2025/03/13/how…
