"Electrons as Math Whizzes," by David Castelvecchi. Science News, 27 September 2008. Two European scientists are attempting to use the energy levels of electronsa concept in quantum physicsto prove the Riemann Hypothesis, a famous unsolved mathematical problem. The scientists hope to show that an electron constrained to movement in two dimensions and subjected to electrical and magnetic fields will have energy levels that correspond to the points at which a special function, Riemann's zeta, has a zero value. In addition to earning the scientists international fame, proving the hypothesis would have an important impact on the study of prime numbers and the frequency of their appearance along the number line. Some are skeptical that this recent work, which so far is only an approximation of a connection between energy levels and zero values, will lead to a solution, but the connection between mathematics and quantum physics is nonetheless interesting.

"The Mathematician And The Pig," by Lionel Tiger. Forbes, 24 September 2008. This opinion piece by weekly columnist Tiger, who is a professor of anthropology at Rutgers University, says that mathematics "defeated" the nation's investment institutions and financiers. He writes that complex financial models "are able to conceal that a bonehead mortgage banker in a suburb of Sacramento sold an alluring house to a propertylusting courtier who couldn't even afford the first date." Tiger says that early humans had to live in the here, the now, and the next moment. Abstract theories about the character of the universe may have been entertaining diversions around the campfire, but far more vital were competent assessments about the realism of others and management of the flow of emotion and enthusiasm that a huntergatherer had to live by. Should a member of a group announce that he just developed a structured investment vehicle which was computationally certified by a computer to contain a plump pig, he would have an immediate challenge from his peersto show them the pig. He concludes that those using the models did not understand them, so "..in the gratifying swirl of lavishly rewarded human optimism, no one remembered to glance at the pig to be sure it was still thereor ever was in the first place."

"X = 50 Semesters," by Manil Suri. The New York Times (Sunday magazine), 21 September 2008, page 110. In this short piece in the Lives column, Manil Suri presents a series of humorous and thoughtful vignettes from his career as a math professor over the course of 50 semesters of teaching. Suri writes about awkward moments such as his first day of teaching, developing comfort with the craft and becoming "addicted to seeing the light go on in students' eyes," a stressful term teaching an oversized calculus class, and a less than successful attempt at convincing a new audienceartists and writersof the beauty of math. He reflects that, "in the end, only the exhilaration of connecting with students through math can keep you going."  Claudia Clark
"Students in advanced math classes are doing worse, according to private researchers [sic] report," by Libby Quaid. Chicago Tribune, 21 September 2008. A study by the Brookings Institution says that more kids than ever are enrolled in algebra in eighth grade, but aren't necessarily learning more math (the amount of encouragement derived from the title of this article may equal the amount of surprise generated in math teachers by that conclusion). Today almost onethird of eighth graders take algebra. The study's author, Tom Loveless, says that many eighthgrade algebra students "don't know very much math at all and yet they're taking courses in advanced math." The report also looked at lowachieving math students, defined as those who scored in the bottom 10 per cent according to the National Assessment of Educational Progress, and found that their enrollment in eighth grade algebra has more than doubled since 1990 and that their teachers are mathematically unprepared. William H. Schmidt, a professor of statistics and education at Michigan State University, replies, "So what's the alternativeto let them continue in eighth grade to take lowlevel or basic math?... My big worry is people will use this [the study's conclusions] to say, 'Aha, see, it ain't working, let's put these kids back where they belong.'" He does agree that students do need better preparation.  Mike Breen
"Prime directive: Ottawa math whiz lands a big one," by Tom Spears. Ottawa Citizen, 16 September 2008. In late August, two Mersenne primes, 2^{43,112,609}1 and 2^{37,156,667}1, were discovered through the Great Internet Mersenne Prime Search (GIMPS), a distributed computing project connecting more than 100,000 computers worldwide. Both prime numbers are more than 10 million digits long, which earns a prize of US$100,000 from the Electronic Frontier Foundation for the first one discovered, the larger number. The cash prize will be shared by Edson Smith, of the UCLA Mathematics Computing Group, where the prime was discovered; and Scott Kurowski and George Woltman, who developed the software for GIMPS. The search will continue. There is now a US$150,000 prize for the discovery of the first 150million digit prime. Jeff Gilchrist, a math Ph.D. student at Carleton University, was part of the verifying process for the larger prime. This is the sixth time that he has confirmed a recordsetting prime number. His nonprime research area involves discovering hidden patterns in vital signs of patients in intensive care.  Mike Breen
"It's Likely That Times Are Changing," by Tom Siegfried. Science News, 13 September 2008, pages 2628. The change is a change in the way some physicists are thinking about how space and time fit together. They are rethinking the connection in hopes of making relativity mesh with quantum mechanics, which may help our understanding of socalled dark energy. Perhaps space and time are distinct, emerging separately from basic elements then merging into "the mirage that human inquiry is able to access." The mathematics in the article involves Hermann Minkowski. Einstein was a studentalthough not a very diligent onein Minkowski's class. Later, Minkowski helped put Einstein's ideas on a sound mathematical footing. With regard to special relativity, Minkowski said, "Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality." The physicists in this article now aren't so sure.  Mike Breen

"Oded Schramm, 46, Mathematician, Is Dead," by Kenneth Chang. The New York Times, 11 September 2008. Oded Schramm, a member of the Theory Group at Microsoft Research, who did groundbreaking work on phase transitions, died in a tragic hiking accident on 1 September 2008. Schramm received many awards in his career: the Clay Research Award, the Poincaré Prize, the Pólya Prize, and the Ostrowski Prize; and was elected to the Swedish Royal Academy of Sciences earlier this year. His work combining probability theory with Charles Loewner's equation in conformal goemetry, now called SchrammLoewner evolution, was an impressive breakthrough. Jennifer Tour Chayes of Microsoft Research said that Schramm's work "was a revelation to both mathematicians and physicists... Any time you can relate two different fields obviously there is huge excitement about that. It just opens up all kinds of new horizons in mathematics." Schramm is survived by his wife, Avivit, and two children. Microsoft Research has posted a page in memory of Schramm.  Mike Breen
"The greatest theorem ever told: London calling with a new multimedia performance in Ann Arbor," by Norene Cashen. Detroit Metro Times, 10 September 2008. Mathematicians have proved to be a genuine source of inspiration to writers, playwrights and filmmakers, as evidenced by the success of works such as Proof, A Beautiful Mind and NUMB3RS. British theater company Complicite has added to this list of mathematicianinspired art with their awardwinning play A Disappearing Number. The play follows the brief life of brilliant mathematician Srinivasa Ramanujan and his relationship with English mathematician G.H. Hardy and draws parallels between this story and the fictional modern tale of Al Cooper, an American traveling businessman whose life changes when he falls in love with an English mathematician. The multimedia presentation includes a large rotating chalkboard in the middle of the stage, which serves not only as a visual aid for mathematics but also as a screen for video projection and sometimes even as another exit from the stage, with actors stepping in and out of it's frame. Cashen remarks that the play is "whirlwind of science, love, loss, genius and hallucination," in which equations and numbers are characters themselves. The United States premiere of the play ran in Ann Arbor's Power Center from September 10^{th} to 14^{th}.  Adriana Salerno

"Mathematical Biology Center Launched, by John Whitfield. Nature, 4 September 2008, page 11. A new center for collaboration between biologists and mathematicians is aiming to address growing concerns about outbreaks of animalborne diseases at the national level. These concerns have led the US Department of Homeland Security to provide partial funding for the center, as diseases such as avian influenza and footandmouth disease appear in headlines worldwide. The National Institute for Mathematical and Biological Synthesis hopes to expand mathematical biology beyond traditional use in the fields of ecology and evolution and apply it to development and immunology. One specific problem the Institute hopes to address is understanding the difference between natural outbreaks and deliberate release of a virus. Similar collaboration occurs, only on a smaller scale, in other parts of the world, such as Europe and Japan, and the Institute appears poised to have an important global impact.  Lisa DeKeukelaere
"Die Facetten der Mathematik (The facets of mathematics)": Review of Kaleidoskop der Mathematik (Mathematical Kaleidoscope), by E. Behrends, P. Gritzmann, and G. Ziegler. Reviewed by George Szpiro. Neue Zürcher Zeitung, 3 September 2008. This book, published on the occasion of the "Year of Mathematics" being celebrated in Germany in 2008, is a collection of articles about the "queen of the sciences". The book is aimed at mathematically talented youngsters and the lay public. The review calls it a "stimulating ramble through mathematics".  Allyn Jackson
"How to keep secrets safe," by Anna Lysyanskaya. Scientific American, September 2008. There are many things people do online nowadays, from keeping in touch with friends, paying the bills, buying and selling pretty much anything, to reading the news and even finding a date. All the personal information exchanged in some of these transactions is now vulnerable to all kinds of attacks. Someone might be interested in reading our personal correspondence, or they might want to pose as us, or even sell our personal information to annoying telemarketers. A somewhat shocking fact is that 87 percent of the U.S. population can be uniquely identified by just their zip code, date of birth, and gender. Mathematicians and computer scientists who work in the field of cryptography are dedicated to finding more efficient ways to keep our information safe, and many specialized protocols have been developed to accomplish this. Encryption protocols ensure that neither the ISP (Internet service provider) nor any eavesdroppers can read messages one sends online. Authentication protocols create "signatures" so that the identity of the sender of a message is verifiable. Anonymous channels protocols (or onion routing protocols) make sure that messages are untraceable to the original sender. And zeroknowledge proof protocols are designed so that for example an online service can tell that someone is a member without knowing their identity. Free software that takes care of all these issues is already available, like the GNU Privacy Guard package (which encrypts messages and signs them), and The Onion Router (Tor) project. The protocols mentioned, as well as some of the history behind them, are described in detail in this article by Lysyanskaya, a cryptographer herself. A common problem with all these strategies is that there is no real certainty that the codes won't be broken, but it's enough to know that any algorithm that breaks these systems would also have to answer a really difficult problem in mathematics.

"Putting the science in fiction", by Carolyn M. Brown. Black Enterprise, September 2008, page 53. This short article focuses on Jonathan Farley, a visiting professor of mathematics at Caltech. Together with a biochemist friend, Farley founded a company called Hollywood Math and Science Film Consulting, which has done consulting for numerous movies and television shows, including the highly popular NUMB3RS. The company helps movie and television producers bring mathematical and scientific accuracy and authenticity to their works.  Allyn Jackson
