    **Long post warning**

    I understand your preference for visual ways of comprehending mathematics. The problem is that such ways can be great for purposes of understanding the concepts* but that's about it. Mathematics is almost like an extra sense organ that shows us things we cannot otherwise see. Sure, you can describe colors in terms of touch to a blind man but there's not much he can then do with it. The equations that everyone seems to hate (sometimes with good reason because of the way they are presented with no motivation - unless you derive an equation yourself from fundamental axioms/assumptions with full understanding of the same, it will mean NOTHING to you, EVER!) are the key to finding out what's truly important about a particular mathematical animal. If a picture is worth a thousand words, the value of an equation is literally infinite because it lets us describe vast panoramas of experience in terms of the few things that really matter - that are really beautiful. An equation is like the strand of DNA that holds all the information that defines a living being, just waiting to be used to create one. It is a matter of profound and personal sorrow to me that most people live their entire lives without seeing how the essence of the universe can displayed on a piece of paper using a few symbols!

    Numbers are probably the least important part of mathematics. Mathematics is about ideas, plain and simple. The idea of a simple triangle, a sphere, a higher dimensional manifold, the ideas of change (calculus). Speaking to a programmer - numbers are merely the input and output to the source code that is the equation. Sure, as a non-programmer (for the most part), I prefer to see a program as primarily the grinder that the input goes through to become the output, but we all know that misses the beauty of what's going on inside.

    The other thing about visual aids is that they are almost always (and I speak from experience) personal - very rarely are they useful to any but a small section of learners. You are very correct that the equations and symbols are but a way of expressing mathematical insight. But they have evolved over the ages (and after passing through many loving hands) to be as nearly consistent as anyone could make them. If you look at original papers by inventors of new ideas and the ideas as expressed in textbooks a hundred years later, you will see what I mean.

    That's the beauty of math and science - the original inventor RARELY understands or can explain his own idea better than his intellectual descendants decades down the road. And this made possible only because we have adopted a symbolism that is stable across the nations and through time and which only keeps getting better. This is why as textbooks in the humanities keep getting more and more complicated over the years, math books (college and later - I did not do high school in the US so I have no personal knowledge of that) keep getting more concise and more lucid and more profound as people keep finding more and more connections between previously unrelated things - thus cutting down on clutter.

    Just a quick example and I'll shut up :). Classical electromagnetism (Maxwell) was a beautiful construct - difficult to understand for the scientists of the time but not too much. Then, it's intimate connections to special relativity were formalized and the resulting equations became much simpler! I'll say it again, because it's so counter-intuitive. Two difficult subjects come together and the amalgam is somehow simpler (partly) because the resulting mathematics is much more elegant and cleaner. There are many stories like this that accentuate the importance of equations and good formalism and notation not merely as a computational aid as so many people believe - but as a means of understanding the deeper connections between ideas.

    It's a good thing I didn't grow up with your definitions of "boring" and "cool". Your statement that math is important is laudable but it is deeply contaminated by the addenda that it is also hard and boring. From my point of view, computing is merely a quaint little example of how a teeny tiny fraction of most aesthetically superb* piece of ... magic is the only word for it ... created by the human race can be applied for purposes of relieving the human mind of repetitive calculations (and perhaps entertainment).

    Teaching with the attitude I inferred from your post (and please correct me if my inference was in error) would simply create a bunch of superficial coders. I've seen firsthand the results of "real-world numerical" teaching styles taken to the extreme in (for instance) early physics education. It prevents students from seeing some of the grandest mysteries ever encountered and how our scientific ancestors frakking solved them instead of just staring stupidly at them. Imparting (among other things of course) the magnificence of the intersection of mathematics and reality (especially in everyday situations) should be one of the critical goals of science education.

    Now, of course I wouldn't advocate that teaching philosophy in a college level programming course - you're there to learn to code, not contemplate mathematical mysteries :P. But we're discussing pre-college stuff. Rarely does one see any but the most superficial math in programming courses and that's fine. What I object to is actually institutionalizing that weird attitude. It's like the difference between a stripper and a ballet dancer - in one case, the details of the music aren't all that important ;).

    Just because the current way of teaching is not the best way doesn't mean that "cool" should be the new standard for good education :P. Cool is fine for kiddies, mature children should be introduced to the concept of "profound" as soon as possible. The horrible way we do it now grants the senile old farts a monopoly over it and that's just stupid.

    What? they had solid state transistors before quantum mechanics was anything but a hypotheses from a math formula.

    http://en.wikipedia.org/wiki/History_of_the_transistor

    The first transistor was not developed until 1947 in Bell Labs. Even (unverified) claims were not made until 1925, long after QM hit puberty :P.
    Also, your phrase "hypotheses [sic] from a math formula" is inexplicable. Further, quantum mechanics (developed in the early 1900s) is crucial in formulating the idea of band structure in a solid ( http://en.wikipedia.org/wiki/Electronic_band_structure ). Without this, even the idea of a semiconductor is meaningless. Perhaps you were confusing solid state transistors with vacuum tube triodes?

    "Yet, how many really get the science behind it?" that sentence make no sense. Science is just exploration.

You can't judge what you don't even think about in most cases.

    I could cite solid state textbooks at the graduate level but that would be overkill for the simple example I picked - wikipedia is quite accurate in that respect.

  12. Again? on How To Make Science Popular Again? · · Score: 1

    Popular again? When was it ever popular? I hope we technocrats aren't the latest victims of the "good ol' days" syndrome.

    My point is that science was never popular. At best it was identified with it's real-world manifestation (that we call technology) and at worst with all the evils that beset the god-fearing majority as a result of some busybodies "who just can't leave well enough alone". I don't think most people really have an opinion on science in the abstract sense until it morphs into something they can see or touch or otherwise sense.

    If this thread is considering the question "how to make tech popular again", there are several answers out there already that are working (slowly but surely). The fact that technology can stand relatively independent of the deeper ideas that create it (assuming there's at least a handful of people who get the big picture) is good - it prevents the emergence of a ruling technocracy (something that I, even as a beginning scientist, have no wish to see in my lifetime). In this day and age, this fact has already made tech popular. But it has the disadvantage of creating a subclass of people that can make and work the technology without having to internalize the accompanying physical insights into how the universe works*. This, by the way, is the only way I've found to explain the engineers who work with terrorists (not their psyches - I'm no psychologist - just the reason it's even possible). Sad as it is, you don't really have to understand the solutions to the mysteries of the Universe that our scientific ancestors spent their lives exploring once some brilliant engineer who has done that figures out how to use that knowledge. Once that original bit of insight from the scientist and the subsequent intuitive leap to tech by the engineer are in place, anyone with the money and minimal expertise can repeat the miracle. The very reproducibility of tech without any need for ritual or mantras may yet prove deadly for science (and indeed, society). In my more idiotic/pessimistic moods, I sometimes wish we had continued to do things like the Pythagoreans. But of course, where discovering the truth is concerned, such dramatized secrecy as exists in pathetic little conspiracies or the big religions ultimately leads to a dead end. Open source ftw, eh? :P

    Anyway, I'm rapidly veering off on a tangent. The main point here was to make that distinction between science and tech and emphasize that science was never "popular" in any meaningful sense of the word. For the hyper-sensitive in the readership, please try not to read any qualitative judgments into that distinction (or if you do, recognize that you're just projecting :P).

Luckily it was a (relatively) straightforward setup and after I got to the point where I wanted to strangle someone (or wreck the lab with a hammer - I'm not too fussy about my violent outbreaks :)) I just swore a terrible oath at the thing and machined a new one from scratch.

    I'm not complaining about the work (it's sorta like having an irritating kid - no matter what, it's still your kid :)), but vacuum leaks can be seriously frustrating, especially the ones that show up with a delay so you have not the slightest farking clue where the damn thing is leaking.

    Since I feel like venting (no pun intended :P), I'll let y'all in on just how one leak checks a vacuum chamber. The leak-checker is just a glorified pump that can pump down to really low pressures. The stuff coming out of the chamber is also directed into a mass spectrometer that is tuned to register and count (usually) helium atoms. You spray helium gas over the outside of the vacuum chamber and if there is a leak, some helium gets sucked in and registers on the spectrometer. The bigger the leak, the bigger the count and a simple calculation converts this into ccs of helium coming in per second with a pressure difference of 1 atmosphere across the leak (1 atm outside and ~0 inside) - that by the way is where the unit standard ccs per min (sccm) or standard cubic feet per min (scfm) comes from - you may have encountered these units in several diverse places (anywhere that gas flows are controlled through pipes). Of course, these days most of this is automated but we have this really cool leak-checker (Air Force surplus from the dawn of time :)) that is so freakin' awesome and not too automated. It's from the 60's and still works perfectly o.O

    The bottom line is that finding a small leak* in a man-sized chamber is difficult to begin with. Imagine how insanely difficult it would be to do this in the frakking LHC!
