  • I need help please. These really look like code words which seem to be related to a Markov Chains:

    It seems to be a math problem to figure out map coordinates where Eigen is a vector of some sort. User name Cauchy3 on Stratics.com is making what he calls poems, it seems to be map coordinates and targets of some sort: Here is his latest ‘poem’: Cauchy3-chain-Eigen values… Markov chains consider two cases. Go to lands with purely honors take the zeroes. Heck to jacks are ones. Know it all but take the good. How Markov chain become multiplications identities. Causes the cases are ones or zeroes. Jacks in boxes are all with zeroes. Both when times up take...

    According to a recent study published by the National Center for Education Statistics (NCES), public school students are outperforming their private school counterparts in fourth grade mathematics and have equaled “private school students in fourth grade reading and eighth grade math.” However, as Shanea Watkins, Policy Analyst in Empirical Studies in the Center for Data Analysis at The Heritage Foundation, explains, these results require greater scrutiny. Some commentators that reference the NCES report believe the study points to a causal relationship—that attending a public school will cause higher academic achievement in math. However, the study focuses on data provided by...

    ...In a report to be released today, the National Council of Teachers of Mathematics, which represents 100,000 educators from prekindergarten through college, will give ammunition to traditionalists who believe schools should focus heavily and early on teaching such fundamentals as multiplication tables and long division. ...The council's advice is striking because in 1989 it touched off the so-called math wars by promoting open-ended problem solving over drilling. Back then, it recommended that students as young as those in kindergarten use calculators in class ....According to their report, "Curriculum Focal Points," which is subtitled "A Quest for Coherence," students, by second...

    NEW YORK -- A public school teacher was arrested today at John F. Kennedy International Airport as he attempted to board a flight while in possession of a ruler, a protractor, a set square, a slide rule, and a calculator. At a morning press conference, Attorney General Alberto Gonzales said he believes the man is a member of the notorious Al-Gebra movement. He did not identify the man, who has been charged by the FBI with carrying "weapons of math instruction." "Al-gebra is a problem for us," Gonzales said. "They desire solutions by means and extremes, and sometimes go off...

    Maths genius declines top prize Photos of the reclusive genius are rare Grigory Perelman, the Russian who seems to have solved one of the hardest problems in mathematics, has declined one of the discipline's top awards. Dr Perelman was to have been presented with the prestigious Fields Medal by King Juan Carlos of Spain, at a ceremony in Madrid on Tuesday. In 2002, the mathematician claimed to have solved a century-old problem called the Poincare Conjecture. So far, experts working to verify his proof have found no significant flaws. There had been considerable speculation that Grigory "Grisha" Perelman would...

    The world of mathematics is in uproar over rumours that its most prestigious prize will be turned down next week by one of its brightest stars. The Fields Medal, the equivalent of a Nobel Prize in mathematics, is awarded every four years to young mathematicians who have made the biggest impact in their fields. It is due to be presented by the King of Spain in a ceremony in Madrid on Tuesday 22 August. But Gregori Perelman, who has been widely tipped to receive it, has resigned his post at the Steklov Institute of Mathematics in St Petersburg, Russia, and...

    A RECLUSIVE Russian has won the mathematical world's highest honour for solving a problem that has stumped some of the discipline's greatest minds for a century - but refused the award. Grigory Perelman, 40, from St Petersburg, won a Fields Medal - often described as mathematics' equivalent of the Nobel prize - for a breakthrough that experts say might help scientists work out the shape of the universe. Besides shunning the award, colleagues say he also seems uninterested in a separate $1 million prize for which he is eligible for his feat of apparently proving the Poincaré conjecture, a theorem...

But only three turned up.

The paper from the scientists who made the discovered is here; and a Sean Carroll (no relation) has a very good explanation on his blog, Cosmic Variance. This discovery happens to work as a great example of just why good science needs good math. As I always say, one of the ways to recognize a crackpot theory in physics is by the lack of math. For an example, you can look at the electric universe folks. They have a theory, and they make predictions:...

Three years ago, a Russian mathematician by the name of Grigory Perelman, a k a Grisha, in St. Petersburg, announced that he had solved a famous and intractable mathematical problem, known as the Poincaré conjecture, about the nature of space. After posting a few short papers on the Internet and making a whirlwind lecture tour of the United States, Dr. Perelman disappeared back into the Russian woods in the spring of 2003, leaving the world’s mathematicians to pick up the pieces and decide if he was right. Now they say they have finished his work,...

"We started looking at what Monopoly would look like if we designed it today," said Chris Weatherhead, a Britain.-based spokesman for Hasbro Inc., which makes the best-selling board game. "We noticed consumers are using debit cards, carrying around cash a lot less." British players might...

    Modern methods of teaching maths which have mystified parents and confused many pupils are to be abandoned six years after the Government forced them on primary schools. The same unit at the Department for Education which devised the strategy now wants teachers to go back to the "standard written method" it abolished. The decision has prompted a backlash from some primary teachers and maths advisers who say children are better able to understand the concept of arithmetic when they break sums down into a series of units. They say the "back to basics" approach heralds a return to the "dark...

    Low participation in math and science activities by girls is keeping them from achieving their full potential and weakening the nation's ability to compete, Education Secretary Margaret Spellings said Monday. "We need definitive insights into what goes wrong, when and why," Spellings said. She asked her department's Institute of Education Sciences to review existing research and determine why girls are not as well represented in the sciences as boys. Schools have put more emphasis on math in the past five years because of the No Child Left Behind law, which requires testing and yearly progress in the subject. "This is...

    In their search for patterns, mathematicians have uncovered unlikely connections between prime numbers and quantum physics. Will the subatomic world help reveal the elusive nature of the primes?In 1972, the physicist Freeman Dyson wrote an article called "Missed Opportunities." In it, he describes how relativity could have been discovered many years before Einstein announced his findings if mathematicians in places like Göttingen had spoken to physicists who were poring over Maxwell's equations describing electromagnetism. The ingredients were there in 1865 to make the breakthrough—only announced by Einstein some 40 years later. It is striking that Dyson should have written about...
