    ... I commit to deploying one unit of the latest generation iDontPollute&trade (patent pending). The proprietary technology uses a revolutionary light-dependent reaction mediated via the thylakoid membranes of custom designed chloroplasts which use light energy to synthesize adenosine triphosphate and nicotinamide adenine dinucleotide phosphate (say that 10 times really fast). This technology, although in its early stages, is already enjoying wide adoption at a global level, see for example .

  3. Re:It starts with the textbooks. . . on A Mathematician's Lament — an Indictment of US Math Education · · Score: 1

    Absolutely spot on. Except I would add one thing. There is no need to create a new textbook. The fundamentals of mathematics have been well established for somewhere between 50-150 years. Let's face it, the current cutting edge of research in mathematics requires 10-20 years of full time training. As a corollary, we do not require a new textbook every year. Or every other year. Or every decade even.

    Books like Courant's Introduction to Calculus and Analysis or Rudin's Principles of Mathematical Analysis are great examples. In fairness, they are a little too advanced, but chapters from them can be used selectively or simpler but equally outstanding presentations can be found.

    And of course, it goes without saying that many / most graduate courses in most areas of study are absolutely spectacular, and one would be hard pressed to find anything comparable elsewhere in the world. As such, the most talented students can chart their own path through the mire (especially if they have an accomplished academic as a close family member), and once they make it to college (if they've received the right guidance along the way), they're in a great spot. But the low % of American science faculty is in part due to the significant handicap American kids have coming up through the weak and amorphous pre-college educational system.

  5. Outsider's perspective on A Mathematician's Lament — an Indictment of US Math Education · · Score: 1

    Disclaimer: I am not familiar with the American High School system, since I first came to the US to attend an Ivy League school. I may sound critical, but please remember, I love being in America, and I am merely pointing out what I came to realize over the years.

    I found that, even in an extremely prestigious American college, the mathematics taught in freshman and sophomore courses was at a similar level to what was broadly taught in the public high school system back in Europe where I came from, as early as 9th grade. I found most my American's colleagues math knowledge to be largely absent, but more importantly, many of them who had not entirely abandoned mathematics were nonetheless not even be aware of what they did not know .

    My impression of why they got to be in this state had to do with the teaching method. The mathematics textbooks used in 'mainstream' courses even in my $45k/year college (i.e. over 20 students in attendance) are useless because they adopt a teaching style entirely devoid of insight and entirely too focused on mindless calculations. I suspect similar methods / textbooks are employed in high school. I found, over time, that I can recognize such a book right away, because they tend to be filled with examples with specific numbers. It doesn't matter if the topic is linear algebra, calculus, multivariate calculus, differential equations, Fourier analyis, they manage to insert 'exercises' with 'insight-building' arbitrary values, e.g. 'integrate 12.51 x^3 / (2.98 x + 1) from 0.1 to 2.31.'

    There's of course nothing wrong with practicing integration (or other) techniques, and in fact back home we've all had to spend a massive amount of time doing just that. There's nothing wrong to being able to quickly and correctly do algebra, with large natural numbers or even arbitrary rational numbers - but that is something that is ingrained early on to the point where it doesn't need revisiting. In fact I would argue I am faster, more accurate, and can perform more complicated algebra, although the last time I was asked to work on it was in 5th grade. By the time you make it to calculus and beyond there's no need to test whether you can evaluate a function at specific values of its parameters (if you cannot do that, you would have failed a long time ago), so looking at the integral of x^3 / (a x + b) is allowing you to focus on the essence of the problem at hand, and not on mindless algebra. (Again, the algebra is mindless because you are supposed to know how to do it by the time you're 10, not because you can outsource it to a calculator or India.) Having examples with actual values is hardly the worst flaw, but it is strongly indicative of the mindset of the author and the teaching method, which I would characterize succinctly as 'lacking insight'. I would not have been able to understand and learn math had I only been exposed to such methods.

    Math is a combination of art and hard labor, and both components are important. Good professors are absolutely essential, more important than even good textbooks. In fact all the good textbooks have already been written, many of them decades and sometimes 100+ years ago, it's just a matter of knowing about them and using them.

  9. Don't paint your house, plant a tree on Painting The World's Roofs White Could Slow Climate Change · · Score: 3, Informative

    According to the recent NYT piece on aging yet brilliant physicist Freeman Dyson:

    Dyson published a paper titled "Can We Control the Carbon Dioxide in the Atmosphere?" His answer was yes, and he added that any emergency could be temporarily thwarted with a "carbon bank" of "fast-growing trees." He calculated how many trees it would take to remove all carbon from the atmosphere. The number, he says, was a trillion, which was "in principle quite feasible."

    You can disagree with his math, but he does raise an interesting point. Sometimes the best ideas are also the simplest.

    As an aside, I noticed that a lot of his critics seem to focus on what happens if you extract too much carbon from the atmosphere - which begs the question of how can Global Warming be an irreversible, extinction-threatening process if it's so 'easy' to fight.
