    Critical thinking is not a part of STEM.

    I hear this a fair amount, and am puzzled. As a physics professor, I'm trying to teach students problem solving skills (usually the engineering and science students). As an astronomy professor, I'm trying to teach students (usually the non-scientists taking the survey astro courses) how to apply the scientific method to figure out what's going on up there and have a functioning BS detector when it comes to pseudoscience.

    The definitions I've heard of this "Critical Thinking" meme seem to indicate that these are the sort "top of the learning pyramid" skills that go with "Critical Thinking", but somehow science remains a mindless technical skill in the eyes of many.

    Pay for the most expensive school, then load your CV with pay to publish articles, and eventually you will get grants and "win"!

    Doesn't work. People evaluating your publication record (your dept. head, your dean, someone reading your CV when you apply for the next job) know which journals are junk pay-to-win rags, and not only discount those items, but then figure you don't know what the heck you are talking about since you even had those useless items on your CV.

    Had you read the summary (not even TFA), you'd see that the "victims" are "the gullible, especially young or naive academics and those from developing countries". Not "the most expensive schools".

    Funding agencies are even more discriminating. When your program has only 10-20% of the funds available needed to fund the incoming proposals, crap like this doesn't even make the first cut in a grant application. Why? There's not enough money available to fund the really good proposals. Go ahead, make my life as a proposal reviewer easier by giving me an excuse to move one of the huge stack to the "do not fund" pile.

Lemaitre was one of the early people working out the connections between GR and cosmology. likely before anyone on slashdot was even born.

    Reading over these comments as a whole (many of which are completely over the top, the one I'm replying to is merely inaccurate), I'm sad that Slashdotters are so ready to respond to something by slinging mud rather than considering the topic of discussion: a cool conference on cosmology.

  10. Re:I wish I could trust "academic experts". on We're Creating a Perfect Storm of Unprecedented Global Warming (popsci.com) · · Score: 1

    I wish I could trust "academic experts". I really do. But all my experiences with academia and academics have been very disappointing.

    The first problem can be summed up with the old saying, "Those who can, do. Those who can't, teach. Those who can't teach, research.". That's exactly what we see in academia: those who couldn't cut it outside of academia with their bachelor's degree end up back in academic circles, often for the rest of their lives. Academia provides a safe playpen for those who were below the standards of the real world.

    Wait.... you're saying you can work in academic research with a Bachelor's? Or you mean that people who can't hack it in the real world go to grad school?

    Speaking as someone who a) serves on graduate admissions committees; and b) advises many graduating bachelor's recipients, it's usually exactly the opposite. It takes a great student to get into grad school, and so the less-great students go get a job somewhere. That's a generalization, of course: great students can go get a job too: but a bad student certainly isn't getting into grad school. Caveat - this is physics. Other fields may differ, but all the sciences I'm familiar with operate in similar fashion. Get further from physical science, get different results. But wait, climate science is pretty closely tied to several physical science, and that's what triggered your post, right? Not sociology.

    The fourth problem is when you take all of the above and add money into the mix. That's when everything really goes to hell. This is a sure-fire way for even the sciences, which are generally among the least-inept of the academic subjects, to become highly politicized. It's no longer just about inept people doing inept research. Now it's about inept people doing inept research but always finding the "correct" results for politicians who need to legitimize otherwise illegitimate practices like carbon taxes and excessive and costly regulation.

    Huh. I review many proposals and papers and have served on funding panels, and can honestly say that I've never seen this in action. You have seen this in action, then.... how and where? I've been pretty impressed with how well funding in my field works, for the most part.

    So when such a flawed system provides results or information for my consideration, I have to take what they're saying with a very, very, very big spoonful of salt grains. None of it can be trusted, from the individual level all the way through to entire fields of study.

    Then there's an awful lot of the physics I teach and research that you apparently don't trust: from F=ma through E=mc^2 to quarks and neutrinos. Which begs the question: what the heck DO you trust?

  14. Re:Physics says its BS. on Professors Claim Passive Cooling Breakthrough Via Plastic Film (sciencemag.org) · · Score: 1

    Learn just a LITTLE physics and you will see that YOU are wrong (and TFA). There is no frequency that does not absorb over atmospheric distances, plus when it hits any solid object. There are only frequencies with LOWER absorption, which is meaningless for these kinds of path lengths.

    I've learned a little bit of physics, and while technically true, what you say is misleading. Visible light, for example, doesn't absorb very much in air (yeah sure, there's some). The air is "optically thin" at visible wavelengths, which means more light is getting through from space to us than not: 75% of the energy integrated over all wavelengths gets down here: most of what's not getting through isn't the visible bits (yay for the ozone layer).

    So, if they can shift energy to come out at 10 microns, which is in a clear bit of the spectrum almost as nice as around 5000 angstroms (visible light), what they say is right: 10 micron IR radiated upwards is mostly checking out back into space.

    Just make sure you're not putting the fancy new film under solid objects, go read about the laws of thermodynamics, solve your favorite radiative transfer equation, and *poof*: cooler thing than you had started with.

  15. "will occupy a spot that crosses the Cincinnati and Kentucky border" Odd, one's city and the other's a state. And the border between them is a river - hard to build an airport across a river.

Getting in the car and trying to select my phone to pair to (after my wife has driven it) is eleven-levels deep into a voice menu that has a hard time understanding you. At least it remembers the pairing on restart, but they weren't thinking about two different drivers at all when "designing" this steaming pile of code.

    Not their actual position, although waving blanket, false statements like that around is what passes for political discourse these days. Actual fact: the current background check system was actually strongly supported by the gun lobby: people who are convicted felons or legally declared mentally incompetent don't have second amendment rights. Or many other constitutional rights, say for example, voting. The current argument (causing the House to behave like the dysfunctional third world legislative clique it apparently actually is) is over the "sounds good!" legislation of "people on the terror watch list shouldn't be allowed to buy firearms". Hmm. So, a law in which denies something listed on the bill of rights to people on a secret government list, who can get on that list simply by someone voicing suspicion, with no procedure for getting off the list (or even knowing if/why they're on it)? Pick anything else that's a legal right (voting? free speech? Self-incrimination? Illegal search and seizure?) and swap that in for "gun ownership" in this scenario and watch everyone across the political spectrum freak out. We tried something like this in the 50's with McCarthy when the enemies were Commies instead of Radicals, and are universally ashamed of that fact in hindsight. Of course the NRA should be objecting to this. I'm shocked that the ACLU, for example, isn't too.

    but... there are no laws in any state which address the question I raised... because it's impractical and can't be implemented, without also bringing along a full firearm registry (which is how they collect sales tax on cars sold between private people, we call then "deeds").

    So, back to my question: how can the techniques allegedly used in the study actually answer the question they purport to answer?

  23. Expanded BG checks impractical on Study Finds 3 Laws Could Reduce Firearm Deaths By 90% (meta.com) · · Score: 5, Insightful

    This "make background checks mandatory for private sales" thing sounds good, but won't work. It won't work for the same reason that no one pays sales tax at a garage sale: you're supposed to do so, but there's no way for the government to enforce the sales tax laws on people who don't hold a business license.

    The existing background check system works because it's tied to firearm dealers' licenses: they've got to do it to keep their business license.

    Ironically, during the Clinton administration the feds went on a "too many people have FFLs, let's make them much more expensive and hard to get!" spree. Which now means that many fewer people participate in the background check system, as a result of another initiative that sounded good to people who have a tenuous connection to reality.

    For what it's worth, if you do go buy a firearm on the internet, odds are really good that you're getting a background check anyway. Why? Because to ship a firearm, it's got to go from FFL to FFL. And the FFL in your town handling your shipment is required to do a background check.

    But, it sure does sounds good to propose such a law: to people who have no clue how things actually work. Which, it turns out, is true of most of the "feel good!" solutions non-gun owners concoct to impose on gun owners. Comes of trying to legislate to match what they see in movies and in cop shows rather than what actually happens in reality. So, I wonder how this study came up with their numbers. Did they just say "hmm, X% of people buying their guns person to person commit a crime, a BG check would magically change that number to 0%"? I suppose it might, if 100% of the people followed the new, easily ignorable law. Considering that they're going and ignoring other, stricter laws to commit their crimes (like, "killing people is illegal"), that sounds rather optimistic.
