Mathematics
Look at the most recent article in the Journal of the American Mathematics Society. Real bounds, ergodicity and negative Schwarzian for multimodal maps.
Abstract: We consider smooth multimodal maps which have finitely many non-flat critical points. We prove the existence of real bounds. From this we obtain a new proof for the non-existence of wandering intervals, derive extremely useful improved Koebe principles, show that high iterates have `negative Schwarzian derivative' and give results on ergodic properties of the map. One of the main complications in the proofs is that we allow to have inflection points.
Am I out of touch, or what? What the blazes are they talking about? Oh, well. I do know that The circumference of a circle is its diameter times pi .

RFID tags on the march.
Now the N.Y. Times story today, Tiny Antennas to Keep Tabs on U.S. Drugs
shows one of the many news stories that they will make this year, I bet. Tracking bulk drug shipment containers so that druggists can verify that the pills are genuine.
As someone interested in words, I do get a kick out of the NYT, obviously talking down to their readers, never mention the acronym RFID, which has been a standard term for a couple of years, at least on the internet, including the Wall-Mart plans to track inventory with RFID, and the Japanese town planning to implant schoolchildren. The Times calls them antennas (antennae?), then labels, and say, "The labels are called radio-frequency identification." but never mention RFID. Strange.

11-11
How's that for synchonacity of corlescence or slipiandority?
11 after 11 on November 11, 2004
and unfortunately, 2004 in binary is 11111010100
not a match.
