Comment I'll say something nice about Comcast for a change (Score 1) 140

Sure you might only get 2-10 Mb/s download compared with other countries many thousand, but the ping times are unrivaled outside a university. If you want high end gaming, it suffices... Part of me longs for 8000 Mb/s internet with low latency because I'm sitting on networking code for an action based MOBA which could allow more players in the same zone than there are people living on Earth now. Forget 64 player limit FPS, have everyone on a single server in a single zone kungfu fighting. But another part of me thinks I wouldn't be able to balance it and it'd be dumb :P

You can bet that if a theory of gravity came out and it threatened the political or economic status quo, it would provoke a political response. When Edwin Armstrong's invention of FM radio started to gain market traction, RCA used it's political influence to have the FCC take the frequency band Armstrong's radios worked on shifted, making all the radios he'd sold useless. And if that had been done today, the next thing you'd have is is an army of PR flacks and FOX selling the public on the idea that FM radio was "tainted engineering".

Climate science isn't politically tainted. That's only PR BS. If you want to see for yourself, use Google Scholar to search for climate science paper abstracts from the early 50s to the 80s -- well before anyone outside the field heard the term "global warming". You'll be able to actually see the scientific consensus shift from global cooling to warming over the course of thirty years, completely outside the public spotlight.

I would.

I've worked in a physics lab (fusion). I've worked in a geophysics lab. Here's the thing about experimental Earth science: you're not working with a idealized, simplified object under controlled laboratory conditions. You are working with something that is immense and messy and which inherently generates a lot of contradictory data. It doesn't make the big picture impossible to put together, it just means it takes a lot of hard to obtain data to shift the consensus one way or the other. It took forty years for anthropogenic global warming to become the scientific consensus; the first papers were published in the fifties and the idea that the world was warming was hotly contested for at least three decades

Contradictory data is something fundamental to empirical science. Empirical science generalizes from contradictory evidence.

When I was in college, "conservative" meant someone who was cautiously pragmatic. Now it refers to someone who adheres to certain conservative axioms -- a radical in other words (radical == "root"). Radicals by their nature prefer deduction from known truths to induction from messy evidence. This is evident in your citing mathematics as the gold standard, despite the utter inapplicability of its methods to geoscience. Mathematics doesn't deal in messy, mutually contradicting truths. Nor does political orthodoxy of any stripe.

That's why "conservatives" latch on to local phenomena -- like the snow outside their door -- that seem to confirm their preconception that the globe is not currently warming. In mathematics the number 9 disproves the assertion that all odd counting numbers are prime. In climate science the medieval warming period in Europe doesn't disprove that the globe as a whole was cooler at that time. To radicals the existence of contradictions in the supporting data is corrupt. To scientists the lack of contradictions in data is fishy.

Left-wing radicals are equally confused by apparently contradictory data points, and likewise seize on the ones that "prove" their universal truths (e.g. that vaccines cause autism).

Comment Re:Stop calling it AI. (Score 1) 78

If you show a very young child (less than a year old, I think) something 'impossible' happening, they will pay attention to it for longer and find it more interesting. So if you hold a ball in the air and let go, but it doesn't fall, or you throw a ball and it goes through a wall, a baby can recognise that those are weird events, and will stare at them for a long time.

If you then give the baby a choice of toys, amongst which is the ball that did an impossible thing, they will spend more time playing with it, rather than equally spreading their attention around. Moreover, they will conduct small experiments that are related to the impossible thing they saw. They will pick up the ball and drop it repeatedly to make sure gravity works. They will hold the ball and bang it on a surface to make sure that the ball does not arbitrarily pass through things.

The brain has a lot of stuff built into it. There are whole sections of the brain devoted to image processing, or understanding smells and taste. These are not inconsequential starting points.

Comment Re:Tolkien saw realistic trees in his imagination. (Score 1) 179

I'm not sure your information on general psychology is accurate, or appropriate.

I've taught tree identification to scouts and scout leaders. I can say from experience that people do not consciously see details, even if they're looking at a specimen right in front of them. It's as if their conscious perception stops as soon as their brain dredges up the word "tree". You can tell a typical person to look at a tree for a minute, then have them turn their back and describe it. What you get, even after you instructed them to look *carefully* at the tree, isn't much more specific than "green blob on a brown stick", and sometimes the stick is is really gray, not brown.

The power of verbal labels to shut down observation is profound. Anything that isn't broadleaf tends to be a "pine", even though pine, fir, spruce, etc. look a heck of a lot less like each other than a oak and Norway maple. It's like someone could't tell the difference between an opossum and a house cat. Most peoples' sense for the shape of a tree is extremely crude; they'll recall extreme shape like an arbor vitae, but they won't see the shape difference between a red maple (globular) and a Japanese maple (spreading).

You have to train yourself to actually see things. It takes conscious effort at first. Sketching or writing detailed verbal descriptions helps.
