Having taken Monday off for the briefest of honeymoons, I returned on Tuesday with an apparently too-cryptic post that required an addendum to make its meaning clear. Thanks to everyone who sent good wishes and congratulations. I am feeling extremely fortunate.
When I announced last week that I’d be taking a couple of days off, readers took the occasion to raise some issues in the foundations of mathematics. This inspired me to write a long-intended post correcting some elementary errors that frequently come up in these discussions. At least one very confused and feisty commenter jumped to the conclusion that I was saying something controversial and that is was his duty to disagree, loudly and repeatedly.
Thursday’s post was about the magic of the past and the technology of the present, which seem roughly equivalent. And on Friday we took on Arizona’s new immigration law and one of its more fatuous defenders.
With no life-changing events scheduled for the coming weekend, I expect to be back, as usual, on Monday.
