- I'd be interested in any solutions or references anyone might find for the
- following problem which I've been thinking about recently.
-
- Problem: Consider the subset of the plane formed by starting with the Cantor
- set placed on the interval [0,1], and for any two points a, b in this set
- we construct the circle centered at a passing through b. Does this set have
- measure zero?
-
- If this were the case we could use this set as a "blanket" which could be
- translated to cover any given circle of radius at most 1, and was of measure
- zero. Such a "blanket" can be formed to cover rectangles of arbitrary
- dimensions, but I'm not sure if it's possible. The above construction is my
- best guess: if it doesn't work, I'd be interested in any other possible
- construction, with proof if possible.
-
- Have fun with it!
