Is it true that cannot be (topologically) dense in ? The paper of Anning and Erdös addressed the case that […]

This talk covered the historical background of the oldest open problem in set theory, and two proofs that for a long time I avoided learning. I promised to post a summary of the talk here. So here it is. The historical […]

So gambling does pay off
