Until recently, the common factor in all the science used to figure out if a piece of art was forged was that it was concerned with the medium of the artwork, rather than the art itself. Matters of style and form were left to art historians, who could make erudite,, but qualitative, judgments about whether a painting was really good enough to be, say, a Leonardo. But this is changing. A paper in this week’s Proceedings of the National Academy of Sciences by Hany Farid and his colleagues at Dartmouth College in New Hampshire uses statistical techniques to examine art itself--the message, not the medium. Dr. Farid employed a technique called wavelet analysis to examine 13 drawings that had at one time or another been attributed to Pieter Bruegel the Elder, a 16th-century Flemish painter. He also looked at Perugino’s "Madonna with Child", a 15th-century Italian - masterpiece lodged in the college’s Hood Museum of Art. He concluded, in agreement with art historians, that eight of the putative Bruegels are authentic, while the other five are imitations. In the case of "Madonna with Child", he analysed the six faces in the painting (Mary, the infant Jesus and several saints) and found that three of them were probably done by the same painter, while the other three were each done by a different hand. The view that four different painters worked on the canvas is, he says, consistent with the view of some art historians that Perugino’s apprentices did much of the work, although there is no clear consensus among art historians. As sceptics will doubtless point out, this is a small number of images. Furthermore, Dr. Farid knew before performing the analysis what results he expected. But he is the first to acknowledge that it is early days for his methodology. He hopes to study many more paintings. By looking at large numbers of paintings that are universally believed to be authentic, Dr. Farid hopes to be able to examine doubtful cases with confidence in the future. Even with the Bruegels--real and imitation--though, Dr. Farid’s results are persuasive. It is tricky to describe exactly what it is that distinguishes the real ones from the imitations, but Dr. Farid says that it can be thought of as the nature of the artist’s brushstroke. Unlike some analyses of Jackson Pollock’s work that have been done over the past few years by Richard Taylor of the University of Oregon, Dr. Farid says his technique could, in principle, be used for any artist. What Dr. Farid did was to convert each work of art into a set of mathematical functions. These so-called wavelets describe particular parts of the image as a series of peaks and troughs of variable height and wavelength. By expressing an image this way, it is possible to compress that image while losing very little information. The sums of the wavelets from different images can then be compared. Once he did this, Dr. Farid found that the types of wavelets used to express authentic Bruegels were noticeably different from those used to express the imitations. (The Perugino was analysed by treating the six faces as distinct paintings.) It seems that curators may s6on be able to add another weapon to their anti-forgery arsenal. Farid’s reaction to the sceptics’ accusations is ______.

Stephen M. Saland, chairman of the State Senate Education Committee, is a conservative upstate Republican, and Steven Sanders, chairman of the Assembly Education Committee, is a liberal New York City Democrat. But when it comes to education, they have much in common. Neither is a fan of the federal No Child Left Behind Law and its extensive testing mandates. Both say that standardized tests are too dominant in public schools today.That has at times put the two education chairmen in conflict with the state education commissioner, Richard P. Mills. (46) During his 10 year tenure, Dr. Mills has turned New York into one of the most test-driven public systems in the nation, requiring students to pass five state tests to graduate.(47) For months now, the legislative leaders and the commissioner have been locked in a little-noticed fight over the future of 28 small alternative public high schools, a fight that may well be the final stand for opponents of standardized testing in New York.Senator Saland and Assemblyman Sanders are doing their best to protect these schools in New York City (Urban Academy, Manhattan International), Ithaca (Lehman Alternative) and Rochester (School Without Walls) and help them retain their distinctive educational approach. (48) Instead of the standard survey courses in global studies, American history, biology and chemistry pegged to state tests, these schools favor courses that go into more depth on narrower topics. At Urban Academy, there are courses in Middle East conflicts, world religions, post-Civil War Reconstruction and microbiology.In the mid-1990’s, the former education commissioner, Thomas Sobol, granted these 28 consortium schools (serving 16,000 students, about 1 percent of New York’s high school population) an exemption from most state tests. That permitted a more innovative curriculum, and students were evaluated via a portfolio system that relies on research papers and science projects reviewed by outside experts like David S. Thaler, a Rockefeller University microbiology professor, and Eric Foner, a Columbia history professor.The Gates Foundation, which has given hundreds of millions of dollars to start small high schools nationwide, is so impressed with these schools, and it regularly sends educators to New York to see how they’re run.But the testing exemption for these schools is about to expire, and Commissioner Mills does not want it renewed. He believes that all students, without exception, should take every test.Recently, Senator Saland defied the commissioner. He shepherded a bill through the Republican controlled Senate that passed 50 to 10 and would continue these schools’ waivers for four years. (49) Senator Saland’s bill does require that students pass the state English and math tests to graduate, letting the state gauge the alternative schools’ performance versus mainstream schools.On the Senate floor, Senator Sa[and noted that while 61 percent of consortium students qualified for free lunches and three quarters were black or Hispanic, 88 percent went on to college, compared with 70 percent at mainstream schools that give state tests.
