- I'll need to curve it some: add 15 to your score.

- Note: there is a homework set due Friday....
- For next time: read section 4.7: The Fourth Dimension
- Section 3.2: Comparing the Infinite
- The ping-pong ball conundrum
- The ping-pong ball conundrum is related to other paradoxical
ideas, such as Zeno's paradoxes
- Section 3.4: stratosphere of infinities
- The Power set
- set of all subsets of a set
- Power sets lead to bigger sets
- this is true even in the case of infinite sets!
- A proof (following the idea of Dodge Ball) that there is an
infinite set too big to be contained in "Motel Infinity".
