1. (difficult) The gravity of the continuum hypothesis has not hit me yet, and it seems like a statement that says "well, duh."
2. (reflective) It is really interesting that the cardinality of a denumerable set is defined as a letter of the Hebrew alphabet. With mathematics begin mainly written in Greek symbols, I wonder how aleph has survived as being a standard symbol. I'm sure at some point the mathematicians would run out of Greek letters and symbols to use, but Hebrew is a surprising alternative.
