  1. Comparison to Neverwet on "Superomniphobic" Nanoscale Coating Repels Almost Any Liquid · · Score: 1

    I wonder how it compares with that 'NeverWet' or Rain X stuff. Apparently, the contact angle of the former for a drop of water is around 160-175 degrees (close to perfect 180), but may have problems with durability (and is pervious to solvents, detergents, soap and high pressure water). The latter - Rain X - is already in commercial use, namely for car windscreens, but only has a contact angle of 110 degrees, so isn't superhydrophobic.

    I refer to my earlier post which gave these stats:

    You're looking at what chess is rather than what it could be. If we randomized the start positions of each piece, or had more pieces/squares, the problem would vanish, or at least lose its sting.

    I think what you've just said sums up the attitude lots of people have in moving towards new standards. People are short-sighted and don't like change, even if it's for the better (or much better). For me, the temporary hard work towards progress would be exciting, rewarding and (as in the case of 'metrication') obviously for the better.

  9. Evolution of ideas by testing on half the states on America's Real Criminal Element: Lead · · Score: 3, Interesting
    This quote from the article sums it up quite nicely:

    In fact, use of leaded gasoline varied widely among states, and this gave Reyes the opening she needed. If childhood lead exposure really did produce criminal behavior in adults, you'd expect that in states where consumption of leaded gasoline declined slowly, crime would decline slowly too. Conversely, in states where it declined quickly, crime would decline quickly. And that's exactly what she found.

    This is why I continue to think that experiments should be performed on half the states at a time, especially if we're not sure about something. For example, the idea to drop working hours to 50-75% of what we have is a 'risky' plan, but could make people much happier. So we try it out on half (or some fraction of) the states. Another idea is to try fluoride in water at 0.1ppm, 1ppm, 2ppm. Similar experiments can be used for chlorine or ozone (I'm not making any judgements on those or saying that conclusions haven't already been reached by the way).

    By experimenting on half (or some fraction of) the states like this, we create a kind of 'evolution', where we can filter out bad ideas, and keep good ones. Or at least more likely be able to do so.

    Well who decides what is badly designed and what isn't?

    Well you've just decided that the English language is (somewhat) bad. And as a speaker myself, I'm somewhat inclined to agree with you. Yes, given enough time, that will change, and I bet we'll also scrap DST, and even switch to base 8, 12 or 16 for our number system within the next half-millennium.

    Organizations such as FCC and IEEE also decide standards, and they do a good job for the most part. We build standards based on reason and consensus, and saying "we'll disagree all the time and nothing will get done, so we should just not bother" is just sad.

    Just like latency in software, and the internet, the effects are insidiously hidden, since they underpin a lot. Teaching metric helps kids to understand the concepts much more easily, and experts may be 'comfortable' with imperial, but they don't really know what they're missing by switching completely to metric. Apart from that, it saves a lot of time converting too.

    I use 'turns' in trig most of the time and am trying to encourage people to do the same. Compare:

    ' Turn based trig (much better for many apps)

    The system itself is far from arbitrary, and makes a lot more sense than imperial. It *is* better - you don't need to put quotes round it.

    White is white, and so a 6500k (or thereabouts) colour temperature is desired for the LCD backlight (being close to the colour of the sun). If you have a problem with the screen displaying a screen which is too bluish, then how hard is it adjust the colour settings on your PC?

    Can you get standard light fitting LED bulbs which put out the equivalent of more like 5000 lumen? I'd love something to replace my 60W CFL bulb (that's actual watt not equivalent). At 200 lumens per watt, that would work out to a 25w LED bulb.

    No, the true future of 3D is what we have now, but tweaked and refined so that 3D objects don't often intrude beyond the front of the screen (there's a gimmick we can well do without). Combine that with a decent frame rate, and a more enveloping view (bigger screen horizontally AND vertically) and then we can talk.

    My brother had a nervous breakdown recently. He was agnostic before, but now believes in two gods, one female and one male. He's otherwise highly intelligent by the way. He 'knows' (just like you) God is real because he speaks to him/her, and 'feels' he's there, like some kind of spirit within his own mind. It's an illusion however.

    This is of course where science comes in. The mind is susceptible to distortions, and misrepresentation of reality, especially when it comes to the supernatural. You sound like another victim unfortunately.
