Dec 31 comment How to answer a student objection to the use of “of” in pronouncing f(x)? joriki "would have told the student to keep up the critical thinking." However Ben Crowell responds "it's time to grow up to a more mature intellectual level." Very interesting.

Oct 17 comment Probability that Scouting ashes continue to circulate? So if I am understanding you, a fire may have on the order $10^{26}$ atoms of ash at the end, and I remove about $10^{24}$ atoms. If I model this as a binomial with $n = 10^{24}$ and $p = .01$, then my expected number of atoms from the original fire is $10^{22}$. After two fires, this goes down to $10^{20}$ and so on, until by fire number 12, my expected value goes below $10^{0}$. Makes sense, if my interpretation is correct?
