    I home school a young girl. In years past, we have gone to the local air show and done such things as measure the tops and bottom of wings and rotos and figure the ratio or difference between the area of the top of the wing versus the bottom and estimated which wings had more lift than others. We measure how much area the wheels occupied on the ground and consulted with the crew chief what the tire pressure was and calculated the weight of the plane. In years past we were able to see F18s form a vapor cone...

One of the greatest astronomers ever, the man who figured out the laws of planetary motion, a genius, scholar and mathematician — in 1611, he needed a wife. The previous Mrs. Kepler had died of Hungarian spotted fever, so, with kids to raise and a household to manage, he decided to line up some candidates — but it wasn't going very well.Being an orderly man, he decided to interview 11 women. As Alex Bellos describes it in his new book The Grapes of Math, Kepler kept notes as he wooed. It's a catalog of small...

    Nearly 90 years after Werner Heisenberg pioneered his uncertainty principle, a group of researchers from three countries has provided substantial new insight into this fundamental tenet of quantum physics with the first rigorous formulation supporting the uncertainty principle as Heisenberg envisioned it. In the Journal of Mathematical Physics, the researchers reports a new way of defining measurement errors that is applicable in the quantum domain and enables a precise characterization of the fundamental limits of the information accessible in quantum experiments. Quantum mechanics requires that we devise approximate joint measurements because the theory itself prohibits simultaneous ideal measurements of position...

    Mathematics has been called the language of the universe. Scientists and engineers often speak of the elegance of mathematics when describing physical reality, citing examples such as π, E=mc2, and even something as simple as using abstract integers to count real-world objects. Yet while these examples demonstrate how useful math can be for us, does it mean that the physical world naturally follows the rules of mathematics as its "mother tongue," and that this mathematics has its own existence that is out there waiting to be discovered? This point of view on the nature of the relationship between mathematics and...

    It is one the oldest mathematical problems in the world. Several centuries ago, the twin primes conjecture was formulated. As its name indicates, this hypothesis, which many science historians have attributed to the Greek mathematician Euclid, deals with prime numbers, those divisible only by themselves and by one (2, 3, 5, 7, 11, etc.). Under this assumption, there exists an infinite number of pairs of prime numbers whose difference is two, called twin primes (e.g., 3 and 5), but nobody has been able to confirm this so far.

    Every pure mathematician has experienced that awkward moment when asked, “So what’s your research good for?” There are standard responses: a proud “Nothing!”; an explanation that mathematical research is an art form like, say, Olympic gymnastics (with a much smaller audience); or a stammered response that so much of pure math has ended up finding application that maybe, perhaps, someday, it will turn out to be useful. That last possibility is now proving itself to be dramatically true in the case of category theory, perhaps the most abstract area in all of mathematics. Where math is an abstraction of the...

    Most people have heard of “evolutionary biology.” But the term “evolution” is often applied in a broader sense (gradual, naturalistic changes over long ages) to other fields of study. Some people study geology or astronomy from an evolutionary perspective. But has anyone ever studied “evolutionary mathematics”? What would an evolutionist mathematician study? Can the existence of numbers and mathematical laws be explained by a time-and-chance naturalistic origin? To answer these questions, let us first consider some background material and definitions. Mathematics is the study of the relationships and properties of numbers. What, then, are numbers? That may seem like an...

These signatures include the size of the hippocampus — a string bean–shaped structure involved in making memories — and how connected the area was with other parts of the brain.

  • Will Dumping Math Requirements Increase College Grad Rates? / worthless college degrees

    HetchingerEd is offering a rather radical proposal to increase the number of American students who graduate college: dump math. Specifically, the argument is that since many college students, a disproportionately large number of them of an African-American or Hispanic descent, are unprepared to tackle college-level mathematics courses, they might be stymied by a requirement that all those receiving a degree from a particular institution must pass the freshman version of the course. A fifth of students entering a four-year college don’t have the needed math skills to pass the course and are forced into remediation. Nearly half of community college...

    If one manages to graduate from high school without the rudiments of algebra, geometry and trigonometry, there are certain relatively high-paying careers probably off-limits for life -- such as careers in architecture, chemistry, computer programming, engineering, medicine and certain technical fields. For example, one might meet all of the physical requirements to be a fighter pilot, but he's grounded if he doesn't have enough math to understand physics, aerodynamics and navigation. Mathematical ability helps provide the disciplined structure that helps people to think, speak and write more clearly. In general, mathematics is an excellent foundation and prerequisite for study in...

On Friday, Emory mathematician Ken Ono will unveil new theories that answer these famous old questions. Ono and his research team have discovered that partition numbers behave like fractals. They have unlocked the divisibility properties of partitions, and developed...

They found that the distribution of the leading digit in the prime number sequence can be described by a generalization of Benford’s law. In addition, this same pattern also appears in another number sequence, that of the leading digits of nontrivial Riemann zeta zeros, which is known to be related to the distribution of primes. Besides providing insight into the nature of primes, the finding could also have applications...

The winner of the 6 million Norwegian kroner (US$920,000) prize, Mikhail Leonidovich Gromov, has held a permanent appointment at the Institute of Advanced Scientific Studies (IHES) outside Paris since 1982. The Abel committee cited Gromov specifically for his contributions to three sub-disciplines of modern geometry: the study of Riemannian space, symplectic geometry, and groups of polynomial growth. Gromov is "renowned among mathematicians for his original approach", says Ian Stewart, a mathematician at the University of Warwick in Coventry. Among other things, modern geometers...
  • The Beal Conjecture

    No one suspected that Ax + By = Cz (note unique exponents) might also be impossible with co-prime bases until a remarkable discovery in 1993 by a Dallas, Texas number theory enthusiast by the name of Andrew Beal. Beal was working on FLT when he began to look at similar equations with independent exponents. He constructed several algorithms to generate solution sets but the very nature of the algorithms he was able to construct required a common factor in the bases. He began to suspect that co-prime bases might be impossible and set out to test his hypothesis by computer....

    Is mathematics the language of the universe?MARIO LIVIO IS an astrophysicist, a man whose work and worldview are inextricably intertwined with mathematics. Like most scientists, he depends on math and an underlying faith in its incredible power to explain the universe. But over the years, he has been nagged by a bewildering thought. Scientific progress, in everything from economics to neurobiology to physics, depends on math's ability. But what is math? Why should its abstract concepts be so uncannily good at explaining reality? The question may seem irrelevant. As long as math works, why not just go with it? But...

    From Sandro Magister of Chiesa, a piece about Pope Benedict XVI's interest in the nature of mathematics within the relationship of faith and science: Scientists of worldwide fame, like Richard Dawkins of England and Piergiorgio Odifreddi of Italy, insistently link mathematics with the profession of atheism. Spread through conferences, articles, and best-selling books, their theories aspire to become a common language and philosophy. In simple terms, the objections to these atheist mathematicians are the ones expressed by a 17-year-old Roman high school student, Giovanni, during a question-and-answer session with the pope in St. Peter's Square, crowded with young people on...

    Mathematicians Land Top Spot in New Ranking of Best and Worst Occupations in the U.S. BY SARAH E. NEEDLEMANThe Wall Street Journal Nineteen years ago, Jennifer Courter set out on a career path that has since provided her with a steady stream of lucrative, low-stress jobs. Now, her occupation — mathematician — has landed at the top spot on a new study ranking the best and worst jobs in the U.S. "It's a lot more than just some boring subject that everybody has to take in school," says Ms. Courter, a research mathematician at mental images Inc., a maker of...

    Nov. 23 -- BURLINGAME -- California's largest teachers union will back a fight in court to overturn the state's new eighth-grade algebra requirement. The Burlingame-based California Teachers Association has joined the lawsuit by the California School Boards Association and the Association of California School Administrators against the state Board of Education's decision to require all middle school students to be tested in Algebra I by the end of eighth grade starting in 2011. The state board "acted abruptly, imprudently and without fully understanding the consequences of its actions on our schools, teachers and students," said David Sanchez, president of the...

    The New York Times recently reported on a study that found, once again, that the United States is failing to develop the math skills of its students, particularly girls, especially compared to other countries where math education is more highly valued. -- Snip--- Bob Compton, an Indianapolis-based venture capitalist and entrepreneur who co-founded Indian Math Online, hatched the idea when he was producing “Two Million Minutes”, a documentary comparing high school education in India, China and the United States. He realized that Indian teenagers who were the same age as his daughters were three years ahead of them in math.

    Not Ready for Algebra by: Irene Warren, November 04, 2008 A trend shows that elementary and advanced math students have fallen below the national average. The Brown Center on Education Policy hosted an event at the Brookings Institution recently to discuss possible ways to better prepare students to succeed in higher-level math courses. “Algebra in eighth grade was once reserved for the mathematically gifted student” the Brookings Institution noted in an October 2008 events announcement. “From 1990 to 2007, national enrollment in algebra courses soared from 16 percent to more than 30 percent of all eighth graders.” However, proficiency scores...

    WASHINGTON: Americans may like to make fun of girls who are good at math, but this attitude is robbing the country of some of its best talent, resear chers reported on Friday. They found that while girls can be just as talented as boys at mathematics, some are driven from the field because they are teased, ostracized or simply neglected. "The US culture that is discouraging girls is also discouraging boys," Janet Mertz, a University of Wisconsin-Madison professor who led the study said in a statement. "The situation is becoming urgent. The data show that a majority of the top...

    French primary school children will be learning multiplication tables by rote and conjugating verbs in the pluperfect tense under a back-to-basics programme to be introduced after the summer holidays. Critics denouced Xavier Darcos, the Education Minister who developed the plan, as old-fashioned, out-of-touch and reactionary, and unions called for a strike over the reform.He responded by saying: “It's not by listening to a great pianist for hours on end that you become one, it's by doing your scales.” The programme is an attempt to prioritise French and mathematics on a primary school curriculum that has been loaded with subjects such...
