  1. Re:Goodbye college football on What Happens When the "Sharing Economy" Meets Higher Education · · Score: 1

    The evidence is phenomenally consistent that the online self-paced stuff works great for professional people who've mastered college-level skills in reading, writing, and math... but falls on its face for people who don't have that. For example, every attempt at getting the horde of people who need algebra remediation through online course has been a disaster. UDacity tried it at San Jose state and was suspended after one semester. Community colleges in Philadelphia tried it and concluded "The failure rates were so high that it seemed almost unethical to offer the option". So I highly doubt you can replace elementary/secondary schools with this method; at that level, most student need a personal face and hand-holding through the material, especially with technical stuff like using, interpreting, and debugging online resources in the first place.

    "Right now, the 15% capital gains tax rate is so high that it discourages middle- and lower-income people from investing..."

    That seems incoherent/illogical. If they can "only" pocket 85% of the free money from investing, what, people make the decision to blow it on a new TV or car instead? And if that rate was changed by 5% or something they'd change their behavior? That's nonsense.

    Bullshit, and a pox on the prequel apologists. As an adult in the last decade or so I've seen all kinds of movies (et. al.) that fill me with equal enjoyment as the original Star Wars movies when I was a kid/teen. Peter Jackson's Lord of the Rings movies, most of the Marvel superhero movies, etc., truly amazing works of wonder. But Lucas' prequels were appalling, offensive crap. Even among the original movies the standout is Empire which he didn't direct.

    For what it's worth, here in New York City (I live in Brooklyn) there are kids all over the place commuting between home & school by themselves all the time. Around 3pm when the schools get out the sidewalks and city buses are literally swarming with the little folks, definitely all ages from elementary through junior high school. They all seem pretty confident, content, and safe about it (if rambunctious). The idea that half the city would have to mobilized to follow around this million-magnitude number kids one-at-a-time would immediately gridlock the entire metropolitan area!

I let that happen to me once at H&R Block and vowed never again.

  21. Pythagorean Theorem on Ancient Planes and Other Claims Spark Controversy at Indian Science Congress · · Score: 2

    The thing about the Pythagorean Theorem is completely true and well-documented (by maybe one or two hundred years). Pretty sure it's in a sidebar to the college algebra text I teach out of.

    Wikipedia: "In India, the Baudhayana Sulba Sutra, the dates of which are given variously as between the 8th century BC and the 2nd century BC, contains a list of Pythagorean triples discovered algebraically, a statement of the Pythagorean theorem, and a geometrical proof of the Pythagorean theorem for an isosceles right triangle. The Apastamba Sulba Sutra (ca. 600 BC) contains a numerical proof of the general Pythagorean theorem, using an area computation. Van der Waerden believed that "it was certainly based on earlier traditions". Boyer (1991) thinks the elements found in the ulba-stram may be of Mesopotamian derivation.[67]... Pythagoras, whose dates are commonly given as 569–475 BC, used algebraic methods to construct Pythagorean triples..."

    [67] Carl Benjamin Boyer (1968). "China and India". A history of mathematics. Wiley. p. 229.
    http://en.wikipedia.org/wiki/Pythagorean_theorem#History

    There's all kinds of examples, maybe more often the case than not, that mathematical principles get named after someone other than the original discoverer. It doesn't even require "forgotten knowledge" or anything like that, just some kind of power relationship at play. In fact, Stigler's Law of Eponomy (named after Stephen Stigler, Distinguished Service Professor at the Department of Statistics of the University of Chicago) states, "No scientific discovery is named after its original discoverer." See also: Matthew Effect and Boyer's Law.

  23. Re:Mod parent up. on Paul Graham: Let the Other 95% of Great Programmers In · · Score: 1

    Well, there's basically nothing preventing people from getting a high school diploma in the U.S.; that's kind of the problem. There are no costs to the student, it's compulsory until age 18 (some exceptions granted for "home schooling" adherents), it's more-or-less disallowed to fail students or hold them back a grade, and standards have become so low that the high school diploma is considered to be of negligible value.

    As an example in New York City (where I am now), the public high schools now boast about a 64% graduation rate [1], but something like 80% or more of those graduates cannot pass a 7th-grade algebra test on entrance to the open admission college [2] (at which point about 20% graduate from that 2-year college). In fact, the majority of graduates don't even have basic arithmetic skills (like knowing times tables, negative numbers, adding fractions, multiplying decimals), and large numbers also need a few semesters of remediation in junior-high level reading & writing skills in English.

    [1] http://nypost.com/2014/12/18/nycs-high-school-graduation-rate-jumps-to-64-percent/
    [2] http://www.villagevoice.com/2013-04-03/news/system-failure-the-collapse-of-public-education/

    So I'm assuming that in Denmark (et. al.) colleges can still take the high school diploma as legitimate proof of mastering those basic skills? Because here we can't. The open-admission community colleges are held out (by politicians, etc.) frequently as a recovery and fix-it shop for the products of high schools who don't really have basic skills. And in fact the pressure is building all the time to remove even Algebra as a required proficiency at the college level, because the community college graduation numbers would then double or triple overnight. [3]

    [3] http://www.nytimes.com/2012/07/29/opinion/sunday/is-algebra-necessary.html

    From that last article: "'There are students taking these [algebra] courses three, four, five times,' says Barbara Bonham of Appalachian State University. While some ultimately pass, she adds, 'many drop out.'". (Personally I've met students taking the basic algebra course for the sixth or seventh time where I teach). So whenever the "free college" proposal comes up, the first thing that pops into my mind is, what is the cutoff for how many times the state pays for a re-take of basic algebra? I am without question 100% all for free college, but it goes without saying that there must some criteria applied, because no body can afford infinite re-takes of junior-high level classes. Right?
