  • The Liberal Arts Are Dead; Long Live STEM

    The Federalist ^ | 6/2/15 | Thielman
    In recent months, Christopher Scalia in the Wall Street Journal and Fareed Zakaria in the Washington Post have defended studying the liberal arts in college, primarily to confront advocates of science, technology, engineering, and mathematics (STEM). Zakaria’s article previewed his new book, “In Defense of a Liberal Education.” From my perspective as a former engineer, two caveats arise regarding their pleas: first, “liberal” education that involves “critical thinking” disappeared decades ago, to be replaced by hyper-sensitive grievance mongering; second, the quantitative reasoning STEM occupations develops also facilitates the understanding of trade-offs people need to make rational decisions among myriad conflicting...

    John Forbes Nash Jr. was a mathematical genius who had his life chronicled in the movie A Beautiful Mind. One of Nash’s colleagues says that just days before he died in a New York taxi cab accident, he had discussed his latest and possibly most brilliant discovery to date. Mathematician Cédric Villan says that Nash told him that he had replaced Einstein’s Theory of Relativity and that the new equation would further explain quantum gravity. The Daily Mail reports that on May 20, 2015, just three days before the tax cab accident that would take his life, Nash spoke to...

Salon’s Jenny Kutner, a strong Davis supporter, concedes that Davis did, in fact, lose.

    In an intentional attempt to study and potentially confuse children, children were asked "There are 25 sheep and 5 dogs in a flock. How old is the shepherd?" Why might you ask this supposedly common-core aligned question? According to the teachers who created this problem, it is to teach students that they must: 1. Explain the meaning of a problem. 2. Plan a solution pathway rather than simply jumping into a solution attempt. 3. Continually ask themselves, "Does this make sense?" This question has actually been researched for years, and is still being asked to children. Today, however, it is...

But thanks to a curious, numbers-savvy Johns Hopkins engineering student and his professor, it may soon get a new lease on life. With just a few modern-day tweaks, the researchers say they've made the rarely used Jacobi method work up to 200 times faster. The result, they say, could speed up the performance of computer simulations used in aerospace design, shipbuilding, weather and climate modeling, biomechanics and other engineering tasks.

    Common Core is on the chopping block. Oklahoma today became the third state to exit the national education standards and reclaim its decision-making authority in education. The move comes on the heels of South Carolina, which days ago put an end to Common Core—setting precedent for other states to follow. South Carolina Gov. Nikki Haley quietly signed a bill withdrawing the state from Common Core, but Oklahoma Gov. Mary Fallin, also a Republican, was not shy about stating her reasons for pulling her state from the national standards. “We are capable of developing our own Oklahoma academic standards that will...

    At the start of morning assembly in the state-of-the-art Viikki School here, students’ smartphones disappear. In math class, the teacher shuts off the Smartboard and begins drafting perfect circles on a chalkboard. The students — some of the highest-achieving in the world — cut up graphing paper while solving equations using their clunky plastic calculators. Finnish students and teachers didn’t need laptops and iPads to get to the top of international education rankings, said Krista Kiuru, minister of education and science at the Finnish Parliament. And officials say they aren’t interested in using them to stay there. That’s in stark...

    The question of how to win at Rock-Paper-Scissors has, believe it or not, plagued mathematicians and game theorists for quite some time. While they previously had devised a theoretical answer to the question, a new experiment by Zhijian Wang at Zhejiang University in China that used real players, has revealed an interesting wrinkle to the original theory. In the experiment, Zhijian noticed that winning players tended to stick with their winning strategy, while losers tended to switch to the next strategy in the sequence of rock-paper-scissors, following, what he calls, “persistent cyclic flows.” Here's how it works in practice: Player...
  • Common Core's Dirtiest Trick: Dividing Parents and Children

    American Thinker ^ | April 15, 2014 | Bruce Deitrick Price
    When you look back at New Math (ca. 1965) and Reform Math (ca. 1990), one of the most striking and persistent features was that parents could not understand the homework which their children brought home. Mystified parents were trying to advise mystified children. The parents, presumably the wise members of the society, were helpless to say anything useful when confronted by the weird complexities of “reform” math, which has now been rolled forward into Common Core. Here is a commonplace horror story that can stand in for millions of others: “When Mike and Camille Chudzinski tried to help their son...

    If the Common Core education reforms introduced by President Obama and supported by big-name Republicans were subject to peer review, they might become a “whatever became of?” question. “Take, for example, my first-grade son’s Common Core math lesson in basic subtraction,” David G. Bonagura, Jr., writes in an article which appeared in The Education Reporter. “Six- and seven-year-olds do not yet possess the ability to think abstractly; their mathematics instruction, therefore, must employ concrete methodologies, explanations, and examples.” “But rather than, say, count on a number line or use objects, Common Core’s standards mandate teaching first-graders to ‘decompose’ two-digit numbers...

    Don't laugh at us old folk. Our data bases are full, so we can't retain what we don't use like we once could. My friend and I need some help from some of you mathematically inclined FReepers. Problem: Mike's sales goal last year was $90,071. His employer increased it to $124,111 this year. What percentage of increase is this, and how did you arrive at the answer? Thanking y'all in advance. :)

    The litany of frighteningly stupid Common Core math worksheets never ends. Perhaps now, though, kids are starting to fight back in satisfyingly creative ways. An alert reader sent The Daily Caller this image of her seven-year-old son’s perfectly reasonable homework answer. The boy attends a public elementary school in San Jose, Calif. He is in the second grade. The math curriculum used by the school is GO Math! The publisher of GO Math! is produced by Houghton Mifflin Harcourt. The parent who sent the homework question to TheDC noted that the curriculum aligns with the Common Core math standards. “If...

    My recent post (my other car is a cdr) brought forth the best of the high-functioning geeks that inhabit this here space. Since the thread veered off (as they always tend to do) into general computer language humor, mostly dealing with Lisp, I got to thinking about RPN (Reverse Polish Notation) and the Hewlett-Packard calculators that were popular in my post-college days working in IT around 1971 or so.Are there other FReepers that still like RPN over infix notation for math? My trusty old H-P has long since departed (wish I still had it) but I've found RpCalc to be...

    College students and others at George Mason University were dumbstruck by the tedious nature of an elementary level Common Core problem during a short series of interviews conducted by Campus Reform last week. The problem, 32-12, was demonstrated to those on campus the traditional way and juxtaposed with the Common Core method.

    Nevada education officials are making it easier for students to pass a math proficiency test that's required for graduation but has proved tough for high schoolers. State board of education officials announced Wednesday that they would implement a pass score of 242 on the 500-point math portion of the high school proficiency exam.
