I so prefer to write dates as 2015-03-14.

The ultimate pi day, 3/14/15, of the century is only a little over a week away. Any good recipes you'd like to share?

Re 24: gosper.org/24throot.pdf DanA>Espcially l and 1 look so similar that I never use lowercase L, and hate to encounter it, in math writing. When I really want to use a non-capital L — typically when giving a talk — I like a scriptish L, like this if it survives e-mail: ℓ ("Script small L" on my Mac). --Dan Amazingly, something xmission.com didn't trash. I wonder why Mathematica doesn't use a less ambiguous font. (And in case you wondered, In[126]:= EntityValue[Entity["Planet", "Earth"], EntityProperty["Planet", "AverageDistanceFromEarth"]] Out[126]= Quantity[0, "AstronomicalUnit"] ) We should also look out for 314th anniversaries of significant things. (picentennials). If we just miss one, "Well, the *real* picentennial is the 314.159th anniversary..." On 2015-03-03 22:13, James Propp wrote:

Adam, Perusing your lovely math blog once again, I noticed your Nov. 10, 2014 post about a new holyhedron with only 12 sides. At first I was very excited, and also amazed he got it so low. Then I read his description of his examples. The problem is, they are not holyhedra. As Conway described the problem to math-fun (as far as I know, this was the first place he publicly mentioned it), a holyhedron is a polyhedron in 3-space that is a connected component of the boundary of a 3-manifold, each of whose faces is not simply connected. More specifically, Conway defined it as a boundary component of a "Boolean compound of finitely many closed half-spaces" — if I remember his wording — each of whose faces, etc. It *certainly* must be a topological 2-manifold, unlike Nathan Ho's examples. But I will need to be reminded how to access the math-fun archives, and check to be sure of his exact words. (I also thought I played some role in the coining of the word "holyhedron" — which I remember Conway felt might offend some religious folk unless an E were added to make "holeyhedron". But again, checking the archives will clarify my somewhat foggy memory about the details of what happened lo those 17 years ago.) Regards, Dan
