Are there as many odd numbers as there are all numbers? Can one infinity be bigger than another? TED Ed
and Minute Physics
both take a look at some of the mind boggling realities of Infinity.

Do you like integer sequences? Do you like poking around in the The On-Line Encyclopedia of Integer Sequences
? Do you think, whoa, wait, okay, actually I like integer sequences but the OEIS is a goddam intractable maze of numbers? Do you think, man, what I wish is that someone would make an accessible blog that discusses some of the interesting entries in the OEIS for the casual fan of integer sequences? Well, that's an amazing coincidence; you should take a look at The On-Line Blog of Integer Sequences

More on arithmetic in the Amazon
The 10/15 issue of Science has the official publication of Peter Gordon's work on numerical cognition among the Pirahã, and a companion article by Pierre Pica et al. on similar research among another Amazonian tribe, the Mundurukú. What with the U.S. election and the discovery of H. Floresiensis, this is not getting nearly as a much play as the pre-publication back in August of Peter Gordon's work.
Brian Butterworth has an piece
in the Guardian about both articles, and I've put some links, quotes and diagrams here
Compared to the reports on the Pirahã, the Mundurukú people, language, and experiments are all somewhat different, although the conclusions are broadly similar.

Sure, they died for their country, but who's counting?!
ABC has a webpage
for US personnel who have died during the war on terror, but it shows only 41 have casualties. Admittedly, they have yet to update their webpage after the latest casualties
, but even if they did, they would still be wrong. CNN recently said
that 47 US personnel have died in Operation Enduring Freedom. That number too is wrong.
To tell the truth, I couldn't find a single story on any major news website that lists all of the US personnel who have died in operation Enduring Freedom, but these sites
appear to be the closest. Neither are fully accurate, however.
A beer on me to the first person who can tell me exactly how many US personnel have died (post 9/11) as a part of Operation Enduring Freedom. Search the web. Find the names. Compare lists
. Extra points to anyone who can offer up some compelling reasons why our media overlords can't keep score. Do we want to know these people's names? Does it matter?!

The Humble Penny?
A site to help visualize large numbers with the common US coin. And to think I've been cursing them for so long. If I'd saved 10 million of the little buggars I'd have $100k.

Counting is profoundly political
The standards used to count (or not to count) Florida ballots is similar to the way the media reports on welfare reform success. It all depends on what you want to consider legitimate. (Happy birthday, Dad!)
