<== This is a picture from the interactive geometry
package Cinderella showing the behavior of 10,000 starting
values in the rectangle [0,1]x[h1,h+1], where h is the height of the
horizontal line, after six iterations of the algorithm which reflects
a point x in the sphere then reflects the outcome in the line and then
averages the result y with x. It is an accessible prototype for a
remarkable image reconstruction algorithm known variously as
DouglasRatchford, LionMercier, Fienup's method, and
"divideandconcur." Some related graphics can be generated and

Quote of the day (refresh browser to select another):
2000 was a banner year for scientists deciphering the "book of life"; this year saw the completion of the genome sequences of complex organisms ranging from the fruit fly to the human. ... Genomes carry the torch of life from one generation to the next for every organism on Earth. Each genomephysically just molecules of DNAis a script written in a fourletter alphabet. Not too long ago, determining the precise sequence of those letters was such a slow, tedious process that only the most dedicated geneticist would attempt to read any one "paragraph"a single gene. But today, genome sequencing is a billiondollar, worldwide enterprise. Terabytes of sequence data generated through a melding of biology, chemistry, physics, mathematics, computer science, and engineering are changing the way biologists work and think. Science marks the production of this torrent of genome data as the Breakthrough of 2000; it might well be the breakthrough of the decade, perhaps even the century, for all its potential to alter our view of the world we live in. Elizabeth Pennisi, from "Breakthrough of the Year: Genomics Comes of Age", Science 22 Dec 2000, pg. 22202221.
