So, another bit of Cantor stuff. This time, it really isn't Cantor crankery, so much as it is just Cantor muddling. The post that provoked this is not, I think, crankery of any kind - but it demonstrates a...

So, remember back in December, I wrote a post about a Cantor crank who had a Knol page supposedly refuting Cantor's diagonalization? This week, I foolishly let myself get drawn into an extended conversation with him in comments. Since...

Poor Georg Cantor. During his life, he suffered from dreadful depression. He was mocked by his mathematical colleagues, who didn't understand his work. And after his death, he's become the number one target of mathematical crackpots. As I've mentioned...

I've been getting lots of mail from readers about a new article on Google's Knol about Cantor's diagonalization. I actually wrote about the authors argument once before about a year ago. But the Knol article gives it a sort...

Another chaos theory post is in progress. But while I was working on it, a couple of comments arrived on some old posts. In general, I'd reply on those posts if I thought it was worth it. But the...

Of all of the work in the history of mathematics, nothing seems to attract so much controversy, or even outright hatred as Cantor's diagonalization. The idea of comparing the sizes of different infinities - and worse, of actually concluding...

Now, it's time for the final chapter in my "visits with old friends" series, which brings us back to the Good Math/Bad Math all-time reader favorite crackpot: Mr. George Shollenberger. Last time I mentioned George, a number of readers...
