Post edited ~5:20p EDT - thanks, [ profile] zwol!

Well, I'm coming back into blogging with a fury, aren't I? First politics, and now religion!

Those of you who do not follow the atheist blogosphere may not be aware of the long, boring back-and-forths between the "New Atheists" and the "accommodationists". To summarize: the latter frequently accuse the former of being mean to theists (people who believe that one or more gods exist) and the former retort that the latter are being intellectually dishonest. What's annoying about it is that the argument never actually connects to the essential disagreement, edit: rarely gets back to actual questions of fact. The latest brouhaha, for example, relates to a question which "New Atheists" answer in the negative and many "accommodationists" answer in the positive: do any people have sufficient intellectual justification to believe that a god is real?

And for that reason, I want to congratulate Larry Moran, who is addressing this question.

This brings me to my challenge. I challenge all theists and all their accommodationist friends to post their very best 21st century, sophisticated (or not), arguments for the existence of God. They can put them in the comments section of this posting, or on any of the other atheist blogs, or on their own blogs and websites. Just send me the link.

(Link via pharyngula.)

If anyone in the audience believes that there are good reasons to believe that a god exists (or has a friend who so believes), please contact Prof. Moran (or have your friend do so) by Saturday, October 2.

As a footnote, though: I realize that there are a subset of people who would answer in the affirmative to the question above without answering Moran's challenge: some people believe that they possess evidence good enough to convince themselves, but that their evidence cannot be communicated to anyone else. Whether this is true is a philosophical question, and one which I would be glad to discuss ... but unrelated to the announcement.

Remember: if you believe that a God exists and you can prove it, or if you know someone who so believes, tell Larry Moran by Saturday, October 2.

Via kirabug, a proper description of the instinctive drowning response:

  1. Except in rare circumstances, drowning people are physiologically unable to call out for help. The respiratory system was designed for breathing. Speech is the secondary or overlaid function. Breathing must be fulfilled, before speech occurs.
  2. Drowning people’s mouths alternately sink below and reappear above the surface of the water. The mouths of drowning people are not above the surface of the water long enough for them to exhale, inhale, and call out for help. When the drowning people’s mouths are above the surface, they exhale and inhale quickly as their mouths start to sink below the surface of the water.
  3. Drowning people cannot wave for help. Nature instinctively forces them to extend their arms laterally and press down on the water’s surface. Pressing down on the surface of the water, permits drowning people to leverage their bodies so they can lift their mouths out of the water to breathe.
  4. Throughout the Instinctive Drowning Response, drowning people cannot voluntarily control their arm movements. Physiologically, drowning people who are struggling on the surface of the water cannot stop drowning and perform voluntary movements such as waving for help, moving toward a rescuer, or reaching out for a piece of rescue equipment.
  5. From beginning to end of the Instinctive Drowning Response people’s bodies remain upright in the water, with no evidence of a supporting kick. Unless rescued by a trained lifeguard, these drowning people can only struggle on the surface of the water from 20 to 60 seconds before submersion occurs.

Read the rest, and read the prequel about cold water survival.

The breakdown is here, if any of you missed it. I find most of these results fairly unsurprising (although the "yellow" region of the saturated color space contains a startling amount of green), but it's really cool to read through the details anyway. Favorite bits:

  • The mnemonic* for how to spell "fuchsia".
  • "Actual color names if you're a [girl/guy]..."
  • The list of colors.
  • The entire "Miscellaneous" header.
  • "Baige".
* Fun fact: I instinctively put a "u" after that "e". Perhaps you can guess how I pronounce that word...

Via Making Light, Paul Cornell: Wish Me Luck, I'm Going In. What with the recent stalling of the Equality Bill in Britain, he's had enough.

I wish there were a Christian organisation like British Muslims for Secular Democracy, who could liaise with the various gay Christian organisations, but also include those who aren't directly involved, who just think this cause is just. Then there would be a phone number for that liberal voice that the UK media could lay their hands on. If they ever wanted to call it.

In the meantime, I've started a hashtag on Twitter: #godlyforequality. If you're on Twitter, go and have a look, and let's see if we can retweet the message a long way. It's only a tiny thing. It's the least I can do.

I'm not a Christian, and I think that Christianity is factually wrong - but what he's doing here is fighting homophobia, and on those grounds he's fighting for the side of good.

Good luck, Mr. Cornell. Do the right thing.

Joshua Kors tells the story.

Luther insisted to doctors at Camp Taji that he did not have personality disorder, that the idea of developing a childhood mental illness at the age of 36, after passing eight psychological screenings, was ridiculous. The sergeant used a vivid expression to convey how much pain he was in. "I told them that some days, the pain was so bad, I felt like dying." Doctors declared him a suicide risk. They collected his shoelaces, his belt and his rifle and ordered him confined to an isolation chamber.

Extensive medical records written by Luther's doctors document his confinement in the aid station for more than a month. The sergeant was kept under twenty-four-hour guard. Most nights, he says, guards enforced sleep deprivation, keeping the lights on and blasting heavy metal music. When Luther rebelled, he was pinned down and injected with sleeping medication.

Eventually Luther was brought to his commander, who told him he had a choice: he could sign papers saying his medical problems stemmed from personality disorder or face more time in isolation.

I can't even joke about this. It's horrible, pure horror.

Via [ profile] roaminrob: Arithmetic, Population, and Energy by Dr. Albert A. Bartlett, uploaded in eight parts. ~75 minutes.

Part One.

I've posted some links because I was curious about your opinion; this one I think is important, clear, and convincing. Unfortunately, I don't see a good way of summarizing it - wonderingmind42, who uploaded it, did a pretty iffy job with the title, in my book - but I'll try: the lecture is about the nature of steady percentage growth (e.g. 7%/year) and the policy implications that come out of the arithmetic. You don't need anything more than multiplication and division to follow the reasoning - the most difficult calculation is for the doubling time, and that goes

years to double = 70 / % growth per year

which is accurate to one part in twenty for any growth rate up to 12%/year.

I think it's worth at least 90 minutes of your time - 75 minutes is a steal at the price.

bliumchik i.e. [ profile] maggiebloome had a tasty, tasty post+links about the sort-of self-destructive anti-ego thing which a lot of women do to avoid seeming too self-confident establish their femininity ...

... and that reminded me of an entirely different self-destructive anti-ego thing that I do, when I don't get things done that I wanted to have done. The thing is, I have this self-image of this feckless, flaky ass who blows off important assignments and mooches financially and emotionally off everyone he meets ... but the whole basis for this persona is that I'm ADD. I don't concentrate well, and I don't have the tools established to work around it (other than "be so clever that you can solve the problem in fifteen minutes or less"...). And given that I'm the only person I have ever met who has given any weight to the ass-hypothesis, I suspect the truth is closer to "my organization skills need a little work".

The self-destructive part, then, is whinging about being a horrible person who deserves to die (a total lie, for the record), rather than doing that little bit of work. Because I can - I have the technology - and everything else is just that I haven't, yet.

Abrupt transition!

A link to pass on: Slacktivist explains the lie Tony Perkins is telling for money about the expansion of hate crime legislation to cover LGBT persons. Money quote:

The only extent to which hate-crime protections pertain to "thought" is in the way that all criminal law does, which is to say that motive matters. If you truly believe that the law should make no distinction between accidental manslaughter and premeditated first-degree homicide, because you truly believe that any such distinction constitutes the establishment of "thought crime," then I will accept that you are making this "thought-crime" objection to hate-crime legislation in good faith. (I'll think you're kind of an idiot, but at least a sincere idiot.) But you can't accept that distinction and still argue in good faith that hate crimes are "thought crimes."

P.S. If anyone you know is concerned that hate crime legislation could infringe their freedom of speech, two words: Fred Phelps.

"What's the easiest unsolved math problem to explain?" I asked my dad tonight, just out of curiosity. I asked because the two obvious, famous answers - Fermat's last theorem and the four-color problem - are both (probably) solved.

Well, I can't guarantee the actual answer is here, but a few candidates he pointed me to:

  • The P = NP problem: if the answer to a computational yes-no question can be checked quickly (in polynomial time), does that imply it may be answered quickly (in polynomial time)? This is a marginal case, as a lot of people don't know what "polynomial time" is, so two better candidates are...
  • Goldbach's conjecture: that every even integer greater than 2 can be written as the sum of two primes, and...
  • The twin prime conjecture: that there exist an infinite number of twin primes - primes separated by two (like 3 and 5). (Bonus: this is a special case of Polignac's conjecture.) However, there are a pair which do not even require understanding primes...
  • The existence of (a) an infinite number of even perfect numbers and/or (b) the existence of any odd perfect number. Perfect numbers being, in these examples, those which equal the sum of all the divisors smaller than themselves - such as 6, equal to 1+2+3, and 28, equal to 1+2+4+7+14.

(Now, one could argue that an even easier hard problem to state is "how come things fall", but that's physics!)

Day before yesterday, Jerry "Tycho" Holkins commented on his fascination with the deeply disturbing "seduction community", and Mike "Gabe" Krahulik stepped in to play devil's advocate.

I completely see where both of these people are coming from, here. But in this particular case, Tycho is very straightforwardly correct, and Gabe's instinctive fairmindness is misplaced. And normally I wouldn't be so confident staking out my spot in this minefield, but I happen to have an advantage: just last month, a completely unrelated community which I have been involved in discussed this question, and the conclusions of the discussion are pretty clear.

The seduction community, or pick-up artist community, or whatever it's called, explicitly treats sexual relations between persons as a game in which the player - singular - seeks to win against opposition. This attributes an explicit status imbalance in which only the man is an actor (cf. Bark/Bite, "Do You Tell a Football What Time the Superbowl Starts?") and in which sexual congress raises the status of the man and lowers that of the woman. It's sexist, offensive, and wrong.

End of line.

P.S. Obviously, two days being an eternity in the wonderful world of cyberspace, I have been preceded in remarking on this discussion - goblinpaladin, pandagon's Amanda Marcotte.

P.P.S. If there are people reading this is frustrated in their desire to find sexual partners, recall that people are complicated. Anyone offering shortcuts is lying.

On Fred Clark's blog, slacktivist:

A: Sarah Palin is lying about health care reform.

B: Whoa, hold on there. That's quite the accusation. You want to use the L-word, you're going to have to prove it.

A: That's not difficult. Here is the outrageous and demonstrably untrue lie in question, from her Facebook page:
The America I know and love is not one in which my parents or my baby with Down Syndrome will have to stand in front of Obama’s “death panel” so his bureaucrats can decide, based on a subjective judgment of their “level of productivity in society,” whether they are worthy of health care. Such a system is downright evil.

She's accusing President Obama of trying to create a "death panel" in which bureaucrats will decide whether or not to euthanize the elderly and handicapped children. That simply isn't true. It isn't close to anything that's close to being true. She's lying.

B: So you say.

A: No, what I say is irrelevant. What matters is what she said versus what the reality is. She is lying.

B: OK, let's just say for the sake of argument that what she is saying there isn't true ...

Enjoy the followup as well.

A man in crazy pajamas atop a skyscraper rains laser death down on the streets. He's laughing as he does it.

Below, fires bloom for the news cameras. Reporters duck debris as they yammer on about demands and manifestoes and terror.
Meanwhile, in the background, the screams of scorched innocents melt into the wail of sirens.

It makes me angry. My cheeks burn with it -- or that just might be from the wind.

I generated the following map shown by entering a comma-delineated list** of my favorite artists and taking a screenshot.

Taylor was in High Fidelity with Tim Robbins who was in The Hudsucker Proxy with Steve Buscemi.

And Steve Buscemi was in Tanner on Tanner with, yes, Barack Obama.

That's only four degrees of separation -- a closer connection than either The Wall Street Journal or The New York Times was able to establish in their exhaustive attempts to find any links between the former '60s radical and the current Democratic nominee for president.

A number of people have been talking about whether intelligent design is scientific recently in some interesting new ways: Megan McArdle, Alex Tabarrok, Robin Hanson, and most notably Thomas Nagel.

The focus of these remarks is best summarized in a post three years ago by Alex Tabarrok:
Suppose that you find a watch in the forest. If you know there is no watchmaker then the theory of evolution is a brilliant and compelling explanation for the presence of complexity without design. But suppose that you know a watchmaker exists then surely the simplest and most compelling explanation is that the watchmaker made the watch. Any other explanation, particularly one so improbable (see extension) as evolution would seem to be preposterous and beside the point.

I can only conclude from the above that these people did not ask themselves, "What do we do science for?"

This is hardly a severe sin, of course. The question is hardly primary among the ones that spring to mind. But the answer is, "Science explains the world in a way which lets us predict the world." This is and always has been where Intelligent Design - and creationism in general - fail: under those views, we have no reason to expect, say, the existence of the punctum caecum (blind spot) in vertebrae eyes but not cephalopod eyes - in fact, just the opposite.

Believing that one or more gods exist is no excuse. The only reasonable explanation for the evidence is that every species now extant is descended with modification from simpler species. And once we hypothesize that, the strictly simplest explanation, even if gods are present, is the modern evolutionary synthesis.

I know some of you all (I'm thinking m'dad [ profile] zhurnaly and the Dread Medievalist [ profile] goblinpaladin for starters) will love this blog, for three reasons.

First, Overcoming Bias is a cool goal.

Second, because it's written by people who know stuff and like to share. (Like Edward Slingerland in What Science Offers the Humanities, and yes, I still owe [ profile] goblinpaladin the review, it's halfway done.)

Third, tasty, tasty writing.

Decoherence is implicit in quantum physics, not an extra postulate on top of it, and quantum physics is continuous.  Thus, "decoherence" is not an all-or-nothing phenomenon - there's no sharp cutoff point.  Given two blobs, there's a quantitative amount of amplitude that can flow into identical configurations between them.  This quantum interference diminishes down to an exponentially tiny infinitesimal as the two blobs separate in configuration space.

Asking exactly when decoherence takes place, in this continuous process, is like asking when, if you keep removing grains of sand from a pile, it stops being a "heap".

The sand-heap dilemma is known as the Sorites Paradox, after the Greek soros, for heap.  It is attributed to Eubulides of Miletus, in the 4th century BCE.  The moral I draw from this very ancient tale:  If you try to draw sharp lines in a continuous process and you end up looking silly, it's your own darn fault.

(Incidentally, I once posed the Sorites Paradox to Marcello Herreshoff, who hadn't previously heard of it; and Marcello answered without the slightest hesitation, "If you remove all the sand, what's left is a 'heap of zero grains'."  Now that's a computer scientist.)

From The Conscious Sorites Paradox, by Eliezer Yudkowsky on Overcoming Bias, as part of a long digression-from-a-digression-from-a-digression-from-a-digression on quantum physics (and, back up the chain, philosophical zombies, reduction, the Mind Projection Fallacy, and ultimately - I think - AI research. Unless ultimately is "Overcoming Bias", in which case ... what am I saying?).

P.Z. Myers on Benedict XVI meeting George W. Bush - outraged, as you should be. Outraged, to a great extent, because in all the "coverage" of this "event", and indeed in the "event" itself, there is not shown the slightest awareness that these men we are seeing praise each other and be praised in return are complicit in horror and terrible horror.

I know I, for one, am tired of this eternal drumbeat of dreadful revelations, each of which has effected not the slightest visible good in its wake. But that exhaustion is no excuse. Each beat of this drum stands for the agony of hundreds, thousands, or millions of people. The least we can do is stand for them.

(P.S. On a much more minor point, Expelled came out today. Do not watch it. Expelled is a terrible movie, morally and cinematically.)
