Cheating: The List Of Things I Never Want To Hear Again. This is an almost definitive list of plagiarism/cheating excuses. I both love and loathe the idea of making students sign a pledge, but there’s that saying about a horse and water… (h/t Daniel Hsu)

This note on data journalism comes with a longer report about how to integrate data journalism into curricula. It strikes me that many statistics and CS departments are missing the boat here on creating valuable pedagogical material for improving data analytics in journalism. (h/t Meredith Broussard)

Speaking of which, ProPublica has launched version 2.0 of it’s Data Store!

DARPA just launched a podcast series, Voices from DARPA, where DARPA PMs talk about what they’re doing and what they’re interested in. The first one is on molecular synthesis. It’s more for a popular audience than a technical one, but also seems like a smart public-facing move by DARPA.

My friend Steve Severinghaus won the The Metropolitan Society of Natural Historians Photo Contest!

My friend (acquaintance?) Yvonne Lai co-authored this nice article on teaching high school math teachers and the importance of “mathematical knowledge for teaching.”


I occasionally enjoy Thai cooking, so I appreciated some of the comments made by Andy Ricker.

I recently learned about India’s Clean Currency Policy which went into effect this year. I still have some money (in an unpacked box, probably) from my trip this last fall, and I wonder if any of it will be still usable when I go to SPCOM 2014 this year. That sounded a bit crazy to me though, further investigation indicates that an internal circular leaked and it sounds like a more sensible multi-year plan to phase in more robust banknotes. My large-ish pile of Rs. 1 coins remains useless, however.

An Astounding Result — some may have seen this before, but it’s getting some press now. It’s part of the Numberphile series. Terry Tao (as usual) has a pretty definitive post on it.

Avi Wigderson is giving a talk at Rutgers tomorrow, so I thought about this nice lecture of his on Randomness (and pseudorandomness).

There’s been a lot of blogging about the MIT Mystery Hunt (if I wasn’t so hosed starting up here at Rutgers I’d probably blog about it earlier) but if you want the story and philosophy behind this year’s Hunt, look no further than the writeup of Erin Rhode, who was the Director of the whole shebang.

Last year I did a lot of flying, and as a result had many encounters with the TSA. This insider account should be interesting to anyone who flies regularly.

A little puzzle

This came up as sub-problem during Young-Han’s group meeting today and we mulled over it for a few minutes but didn’t come up with a non-ugly answer. I’m sure, given the number of Real Mathematicians ™ who read this, that someone out there knows of an “obvious” explanation.

Suppose I give you p integers in an arbitrary order (where p is prime). While maintaining the order and using only addition, multiplication, and parenthesis, is it always possible to make an expression which evaluates to 0 mod p?

I think it’s true, but I’m sure there’s some special property of \mathbb{F}_p that I have forgotten. I guess further generalizations would include whether or not it’s possible for arbitrary p (not necessarily prime), how many elements of an arbitrary field you would need, and so on. I’d ask this on MathOverflow but… meh. It’s probably a homework problem.

support and discounts for developing countries

I’ve been catching up on my magazine reading and an ad from the AMS Book & Journal Donation Program in the December issue of the Notices of the AMS caught my eye. The program is designed to improve access to mathematical materials in developing countries via donations. The AMS already has discounted membership fees for those in developing countries, and in general the mathematics community seems more sensitive to these kinds of disparities.

I looked around a bit to see if the IEEE had any sort of book donation program, but it doesn’t seem to be an institutionally supported thing. The scalable computing people have a page on donations, but I didn’t see one for the main IEEE page. There are no discounts listed on the subscription price list. It seems like more could and should be done. Just putting more things online isn’t going to fix everything. There is a value in having actual books in a library too.

So what can be done? In terms of textbooks, there are already cheaper editions available from most of the major publishers, so that doesn’t seem to be the bottleneck. Setting up a clearinghouse (as the AMS has done) for more research-oriented titles seems like a relatively simple thing to do. Providing a tiered-pricing scheme for journals would be a next good step. If the impetus for this comes at a high level in the IEEE, it might get chapters (and undergrads!) engaged in helping gather materials, solicit requests for donations, and so on.
