Re: Why don't we have 1/1 math?
What does 1/1 math mean? Does it mean 1/1 pure math? If so, Caleb is right about this being independent of the sciences, but I think there probably isn't enough interest in writing or playing this much pure math. Does it mean 1/1 math as scientists interact with it? If so, James and Geoffrey make re...

Re: Lederberg 3: Specific Question Discussion
One correction: in the tossup on the Laplace transform in packet 8, there is an error in the clue about moment generating functions. The moment generating function evaluated at t=x is the two-sided Laplace transform of the PDF of evaluated at t=-x. Also, this may be because they were never covered i...

Re: Lederberg 3: General Discussion
Thanks to all the editors and writers of this set - I loved playing it, and was really glad to see so many exciting new answer lines. I did feel that some of the pure math in the set fell short of rewarding "science as it is taught in the academy." I'm thinking here of tossups like "a...

Also, I wasn't a fan of the "sigma-algebra" tossup because based on the pronouns it was difficult to tell whether or not you wanted sigma-algebra or just measure. This tossup confused me too, especially the clue about the Kolmogorov 0-1 law. I've usually heard it as referring to tail even...

A procedure to determine this value computes the largest value of k satisfying an upper bound of “k over m times this value.” That method, the Benjamini-Hochberg procedure, is used in a setting that analogizes this value to a portion of the “discoveries.”...

Re: Packets, recordings, and detailed stats warm-up survey

Re: Math Monstrosity - General Discussion
There were a lot of things in this set I was happy to see come up, and I'm glad I got to play it. That being said, I had a few systematic issues with the set (some of which have already been mentioned in one form or another): 1. Several things weren't repeats per se, but occupy the same small slice ...

On a completely different note (and one that I had forgotten about until now): I really liked the tossup on the birthday problem. I think it's really cool to see more "recreational"-type math being tossed up -- I feel like oftentimes tournaments that only have 1 math per round stick to th...

Re: Specific Question Discussion
Could I see the tossups on primes and variance please? I'll also add that I was frustrated by the tangrams tossup as well, since they don't seem to have any importance other than being a cute puzzle, and aren't really something you would hear about while learning math.

Re: Question-specific discussion: 2016 DII ICT
The specific issue I had with the Catalan numbers tossup was the instruction to not prompt on trees, which is pretty bad considering that there are plenty of kinds of trees other than binary ones the Catalan numbers count (see http://www-math.mit.edu/~rstan/ec/catadd.pdf).
