I get the larger point, but the answer to your specific question doesn't look too bad... just use

Clicking on that from a mobile gives you the option to open the link in the YouTube player. Isn't that what you say you want in the thread you linked to?

It depends if what you are interested in is solely the experience of watching the content, or if you also care about the cultural experience of discussing it with other people.

Super Principia Mathematica 325

Posted by samzenpus
from the read-all-about-it dept.
An anonymous reader writes "This is not an ordinary book and extraordinary would still be an understatement. Robert Louis Kemp has built a plateau of quod erat demonstrandum (Q.E.D.) in math, physics and logic; defined as his Super Principia Mathematica. Beyond brilliant, Kemp has worked on his book for over two decades, sacrificing personal comfort and financial security to laboriously bring to fruition his textbook style, hardback, expertly illustrated principles to the understanding level prevailed by most people. By 'most people' he means those who have a basic understanding of mathematics, geometry, algebra, calculus, physics and most importantly possessing the curiosity to learn."

As a professor, I have two tasks that I must perform in every class I teach. I must educate my students, and I must evaluate their work. No one has ever explained to me how the 'evaluation' process can reasonably work in an on-line setting. Nothing is stopping me from enrolling my girlfriend's cat in an on-line degree program and taking all his tests. I assure you, Marvin's grades will be very good, but I don't suggest you hire him; he would be sleeping on the job an awful lot.

It's a shame, because I think that for many students, these kinds of programs could provide an education as good or better than a traditional classroom for a much lower price. But until there is a good reason to take the final transcript seriously, I don't think it will ever really catch on.

Laughing Gas Is Major Threat To Ozone Layer 306

Posted by timothy
from the damn-you-street-racers-damn-you dept.
Hugh Pickens writes "The Christian Science Monitor reports that according to new research, nitrous oxide, the colorless, sweet-smelling gas with a long history as a medical and dental anesthetic is the next big threat to Earth's protective ozone layer. Its role in destroying ozone has long been recognized, as well as its role as a heat-trapping greenhouse gas but the new study puts nitrous oxide's ability to deplete ozone into numbers comparable to those used for other ozone-depleting gases covered by the 1987 Montreal Protocol. The researchers note that the health of the ozone layer has been improving since the adoption of the protocol and that nitrous oxide looms large today as an artificial destroyer of the ozone layer, in part because the emissions of other harmful chemicals have been so sharply reduced."

This is the fundamental aspect of business that many in washington do not understand. Any move you make to increase operating costs in the US will simply result in the gradual movement of those industries affect to other countries that are less expensive to operate in.

Unless you can get the UN to jam this system down the throats of every industrialized manufacturing country, it's just going to make the US economy worse while helping the economy somewhere else. Not a big problem while the US was booming, but definitely counter productive under the current situation.

I'm curious, do you have any specific examples in mind? Because it seems to me that, for most manufacturing companies, the cost of energy is dwarfed by the cost of labor, which can already be found much cheaper in other countries (China being the primary example). I would guess that many companies that continue to manufacture in U.S. have very good reasons for remaining here, besides cost. (For example, military manufacturing, power generation, etc). We're simply not the dominant country for manufacturing anymore, and that's not likely to change anytime soon.

However, a huge share of global business is in products developed or marketed by U.S. firms. A major point of the regulations, reinforced by TFA, is to spur technical development which allows U.S companies to stay in front in this respect. China will eventually improve it's greenhouse-gas emission regulations; they don't want their coastal cities flooding any more than we do. If, by that point, US companies have off-the-shelf tech that China can buy to meet those regulations, they will, and US companies will continue to lead.

Were Neanderthals Devoured By Humans? 502

Posted by timothy
from the subsumed-or-consumed dept.
Hugh Pickens writes "The Guardian reports that a Neanderthal jawbone covered in cut marks similar to those left behind when flesh is stripped from deer provides crucial evidence that humans attacked Neanderthals, and sometimes killed them, bringing back their bodies to caves to eat or to use their skulls or teeth as trophies. 'For years, people have tried to hide away from the evidence of cannibalism, but I think we have to accept it took place,' says Fernando Rozzi, of Paris's Centre National de la Récherche Scientifique. According to Rozzi, a discovery at Les Rois in south-west France provides compelling support for that argument. Previous excavations revealed bones that were thought to be exclusively human. But Rozzi's team re-examined them and found one they concluded was Neanderthal." (Continued, below.)

Greenhouse gasses unquestionably contribute far more to recent warming than solar activity, although solar activity is definitely a factor.

I question it. NASA also questions it. Quote: "Indeed, the model suggests aerosols likely account for 45 percent or more of the warming that has occurred in the Arctic during the last three decades."

Agreed. The aerosol question is interesting. I was only commenting on the relationship between greenhouse gases and solar output. I agree that these are not the only factors. I don't know of any serious (ie peer-reviewed) model which attributes nearly as much recent warming to solar output as ggs.

And sure, that's all (well, mostly) anthropogenic, but it's not the dreaded carbon dioxide (which actually has a much lower greenhouse effect than the water vapor in the atmosphere).

Well, yes, but the amount of H2O in the air is relatively stable.

Correct. Other bodies in the solar system are warming as well. Climate scientists know this. In fact they know there are a number of factors which can influence the temperature here on Earth. That's why they've performed many experiments and collected enormous amounts of data to determine to what extent each factor could possibly be responsible for the warming we've seen. Greenhouse gasses unquestionably contribute far more to recent warming than solar activity, although solar activity is definitely a factor. This is all summarized on the Wikipedia entry for Global Warming (with appropriate sources).

As a broader point, science is hard. Blogs, news reports and movies will never accurately convey it, and often intentionally mislead. The only thing that makes sense to me is to trust the scientists. The (US) National Academy of Science in particular is filled with very, very smart people and has a historical record of speaking purely from scientific considerations (ie, it's objective). They believe that anthropogenic climate change is real and significant. No scientific body of remotely comparable credibility disagrees; virtually all similar institutions from other countries have reached the same conclusion.

I'm not a climate scientist, so I don't know with firsthand certainty the truth of the matter. But, forced to choose (for example, as a factor when deciding whom to vote for) I listen to the most trustworthy organization I can find. And their conclusions are clear.

What's interesting is that the intellectual property lawyer behind the move, Horacio Gutierrez, has just been promoted to the rank of corporate vice president at Microsoft. Is this his way of announcing that he intends going on the attack against Linux?"

Best Introduction To Programming For Bright 11-14-Year-Olds? 962

Posted by timothy
from the don't-forget-cty-and-other-nerd-camps dept.
firthisaword writes "I will be teaching an enrichment programming course to 11-14 year old gifted children in the Spring. It is meant as an introduction to very basic programming paradigms (conditions, variables, loops, etc.), but the kids will invariably have a mix of experience in dealing with computers and programming. The question: Which programming language would be best for starting these kids off on? I am tempted by QBasic which I remember from my early days — it is straightforward and fast, if antiquated and barely supported under XP. Others have suggested Pascal which was conceived as an instructional pseudocode language. Does anyone have experience in that age range? Anything you would recommend? And as a P.S: Out of the innumerable little puzzles/programs/tasks that novice programmers get introduced to such as Fibonacci numbers, primes or binary calculators, which was the most fun and which one taught you the most?" A few years ago, a reader asked a similar but more general question, and several questions have focused on how to introduce kids to programming. Would you do anything different in teaching kids identified as academically advanced?

instruction book that we wrote to describe physics?

There's the thing that you don't understand. We didn't create mathematics to describe physics,

I don't know quite who you mean by we, but Newton (along with many, many others) actually were trying to describe physics when they created mathematics. As stated above, it's not too much of a surprise that they eventually got it right.
