Test your tonedeafness

Tim Bray alerted me to a fascinating on-line test of pitch perception, called Test your musical skills in 6 minutes!

While working at the music and neuroimaging lab at Beth Israel/Harvard Medical School in Boston, I developed a quick online way to screen for the tonedeafness. It actually turned out to be a pretty good test to check for overall pitch perception ability. The test is purposefully made very hard, so excellent musicians rarely score above 80% correct. Give it a try!

To my amazement, I scored 94.4%.

Optimism in its purest form

I just checked in (online) for my flights back to Seattle on Sunday. I’m due to depart Boston at 6:00am and land at IAD (Washington Dulles) at 7:49am; allow a few extra minutes to taxi to the gate. Meanwhile my flight from IAD to SEA is supposed to start boarding at 7:50am, and to push back at 8:20am.

Oh yes: the BOS-IAD flight has an 87% on-time record.

Wish me luck….

Pinker rips Harvard on the balance between science and religion

Via Charles and the WNMTC* list comes this forthright piece by Steven Pinker on the subject of Harvard’s Report of the Committee on General Education. First, he objects to the way in which the Science and Technology Requirement is justified:

The report goes on to emphasize the relevance of science to current concerns like global warming and stem-cell research. It even mandates that courses which fulfill the Science and Technology requirement “frame this material in the context of social issues” (a stipulation that is absent from other requirements). But surely there is more to being knowledgeable in science than being able to follow the news. And surely our general science courses should aim to be more than semester-long versions of “An Inconvenient Truth.”

Pinker argues that the importance of science is intrinsic, in language that expresses more eloquently the position that I expressed in my last blog piece (my emphasis):

Also, the picture of humanity’s place in nature that has emerged from scientific inquiry has profound consequences for people’s understanding of the human condition. The discoveries of science have cascading effects, many unforeseeable, on how we view ourselves and the world in which we live: for example, that our planet is an undistinguished speck in an inconceivably vast cosmos; that all the hope and ingenuity in the world can’t create energy or use it without loss; that our species has existed for a tiny fraction of the history of the earth; that humans are primates; that the mind is the activity of an organ that runs by physiological processes; that there are methods for ascertaining the truth that can force us to conclusions which violate common sense, sometimes radically so at scales very large and very small; that precious and widely held beliefs, when subjected to empirical tests, are often cruelly falsified.
I believe that a person for whom this understanding is not second-nature cannot be said to be educated. And I think that some acknowledgment of the intrinsic value of scientific knowledge should be a goal of the general education requirement and a stated value of a university.

Pinker then rips into the Reason and Faith Requirement:

First, the word “faith” in this and many other contexts, is a euphemism for “religion”…. A university should not try to hide what it is studying in warm-and-fuzzy code words.
Second, the juxtaposition of the two words makes it sound like “faith” and “reason” are parallel and equivalent ways of knowing[…]. But universities are about reason, pure and simple. Faith—believing something without good reasons to do so—has no place in anything but a religious institution, and our society has no shortage of these. Imagine if we had a requirement for “Astronomy and Astrology”… [I]t may be true that astrology deserves study as a significant historical and sociological phenomenon. But it would be a terrible mistake to juxtapose it with astronomy, if only for the false appearance of symmetry….
Third, if this is meant to educate students about the role of religion in history and current affairs, why isn’t it just a part of the “U.S. and the World” requirement? Religion is an important force, to be sure, but so are nationalism, ethnicity, socialism, markets, nepotism, class, and globalization. Why single religion out among all the major forces in history?

He concludes:

For us to magnify the significance of religion as a topic equivalent in scope to all of science, all of culture, or all of world history and current affairs, is to give it far too much prominence. It is an American anachronism, I think, in an era in which the rest of the West is moving beyond it.

Exactly.

How do people reconcile science with the idea of an afterlife?

In all of the recent brouhaha over theism, atheism, and science (especially evolution), there’s one question which I haven’t seen much discussed. Since I can’t see an obvious answer, I thought I’d blog about it.
This question is specifically addressed to those people who accept the current state of brain science, and who also themselves as Christians (or Muslims, I guess). What kind of “brain science” am I talking about? Well, check out Wikipedia on neuropsychology, specifically cognitive neuropsychology. Read about the ground-breaking Phineas Gage and HM cases. Do you find these accounts convincing? Are they consistent with the relationship between the brain – its physical structures and electrochemical operation – and human behaviour, personality, cognition, and so forth? Of course we don’t understand all of the mechanisms and relationships today, but if you believe that science is broadly “on the right track” in these areas, then I’m talking to you.
I have no idea how many people meet these two criteria, but I assume it’s quite a large number. My question for them is not about belief in god. I’ve heard so many different definitions of the term “god” from so many people that, frankly, I’m not sure that it’s particularly useful. Instead, I want to know if you believe in life after death, and if so how you imagine it. Do you believe that you continue to exist after your physical body is dead, and if so in what form? Pehaps more important, in what sense is that which survives you? Does it have your memories, your personality, your beliefs and desires?
It seems to me that this question ought to be more productive than one about god. After all, we have a rich culture of stories revolving around notions of identity, “possession”, and so forth, from Greek mythology to Kafka to Star Trek. We may disagree on the plausibility of certain stories, but we don’t have much difficulty understanding and discussing them. So even if you can’t explain what it might be that survives you, you probably have an intuitive and accessible sense of what it means for it to be you that survives.
I’m sure you can see where I’m going with this question, but let me elaborate a bit, assuming that you believe in life after death. (If you don’t, I’m curious as to how you square this with your professed religious affiliation.)
First, how do you conceive of this something that lives on? (You probably use some term like “spirit” or “soul”, but those are ambiguous and suggestive; let’s just call it WPAYPD, for what persists after your physical death). You’ll have to educate me, because I don’t have any idea what you’re talking about here. Even if you can’t explain what it is, can you at least explain in what way it is you? What characteristics does it possess? How are these characteristics of your WPAYPD related to the stuff your brain does?
[A short digression. When I say that I don’t have any idea about this, I’m talking about the explanatory step, not the intuitive one. I’m pretty sure that you and I experience first-person consciousness in very much the same way. However when I think about “what’s really going on”, I understand it purely as “natural processes happening in my physical brain”, with no supernatural stuff involved. I’m pretty sure that people who believe in life after death have a different explanation, but I have no idea what it is.]
However you conceive of the relationship between brain and WPAYPD, I assume (correct me if I’m wrong!) that you believe that this relationship ends at the moment your brain ceases to function. Does that mean that the enduring properties of WPAYPD are determined by the state of your brain at the moment of death? If so, I wonder if you could comment on this thought experiment.
Let’s consider three plausible scenarios. In one, you live a happy life and die suddenly from a massive coronary on your 40th birthday. WPAYPD continues to exist. It has certain characteristics. In the second scenario, you suffer a Gage-like acident on your 40th birthday. You live for 10 years, during which time your personality and beliefs are observed to change dramatically. You become morose and belligerent. Then you die, survived by your WPAYPD. Are these two WPAYPDs the same, or different? Why – and how? If it makes sense for your WPAYPD to have a “personality”, is it happy or morose?
In the third senario, you contract a wasting neurological condition which leads to an inexorable loss of brain function. By the time you actually die, your brain has shrivelled to almost nothing, and you are effectively a vegetable. What of your WPAYPD now?
(When I mentioned this to a friend, he said, “Oh, that’s easy. It’s the real you” But this means that the “real” you is necessarily a-temporal and non-contingent, which seems deeply impoverishing, not to mention incompatible with the variety of free will that most religions espouse.)
Most believers think of life after death, souls, spirits, etc. as stuff which is intrinsically supernatural; they’d argue that it doesn’t make sense to ask for a natural explanation of a supernatural phenomenon. That’s why discussions of god between theists and atheists are often so unproductive. However, in this case the believer in life after death is talking about supernatural concepts that are intimately related to our intuitive notion of “self”, as well as our scientific understanding of mind, brain, and behaviour. So how do you think (or feel) about the relationship between the natural and supernatural, as it applies to the idea of life after death? Compartmentalization? A “mystery”? Predestination? And do you appreciate why I’m puzzled about how you deal with it?

Back to New England for Thanksgiving

I just arrived back in Brookline for a quick visit over Thanksgiving. I’ll be returning to Seattle on Sunday.
U.S. newspapers and TV always make a great fuss about the fact that the day before Thanksgiving is the busiest travel day of the year. These reports are inevitably accompanied by film of long lines at airport security, and interviews with frustrated people who’ve been stranded somewhere.
My experience today was… different. I caught a bus from Seattle to the airport, which arrived on time. I’d checked in online, and I only had a carry-on bag, so I walked up to one of the security checkpoints. There was nobody there, except for some bored TSA staff. Several of them competed for the chance to inspect my photo ID, and then advised me to go to a particular X-ray/metal detector because “they haven’t had any customers.” As I approached, three TSA staff sprang to attention, offered me plastic trays for my lap-top and my shoes, and waved me through the metal detector with a smile.
It all felt very strange… and rather spooky.
After that, everything went beautifully. I had time to hang out at the Red Carpet Clubs in Seattle and Chicago. My flight to Chicago was full, but conditions were smooth and it arrived 30 minutes early. My connection to Boston was 60% full, and arrived on time. Everything was completely uneventful (the highest accolade).
I’m still trying to work it out. Maybe it’s just me.

Music and reading made it all even more pleasant. At Seattle I found the new Jack McDevitt novel, Seeker, which came out in paperback a couple of weeks ago. I’ve already reached page 176. And for the first part of the SEA-ORD flight I got out my iPod and listened to Concrete: In Concert at the Mermaid Theatre by the Pet Shop Boys, which arrived from Amazon.co.uk last week. Most of it is excellent: the only problems are a couple of the “special guests” who aren’t all that special. But the rest is outstanding; Neil is in great form, and the sound (with a live orchestra) is wonderful. Highly recommended.

WiFi oddities

I’ve been experiencing some odd WiFi behaviour over the last week or so. The main symptom is that at random intervals my signal strength will fade away to almost nothing; in addition I’ve experienced spells when my signal looks OK but bandwidth to the Internet is lousy. At times things are so bad that I can’t even stream audio from my PowerBook to the Airport Express (which is connected to my home theatre). The distance shouldn’t be an issue: 12 feet through a thin wall. (And it’s not the Mac: I see the same problems from my Amazon-supplied Compaq nc6000 when I use it at home.)
I downloaded a WiFi monitoring tool called iStumbler to see what was going on. Here’s part of the screen:
iStumbler screen
My network is chaucer (hat tip to Kate), and the base station is easily the nearest. But there are a lot of networks, as you can see (12 right now, at 1 A.M. – at 9 P.M. there are 15-20 active). Most access points try to use channels 1, 6 and 11 to minimize overlap; I’m guessing that my occasional signal loss occurs when my Airport Express decides that the channel it’s using is too crowded, and switches to another one.
The other odd thing is the presence of two networks crackhouse and ACTIONTEC. I think they’re relatively new. What’s distinctive about them is that they are always the strongest signals, and they run almost flat out all the time. I don’t know what the units are on the “signal” and “noise” columns, but chaucer‘s signal is typically in the range 35-45, crackhouse and ACTIONTEC are 55-65, and everybody else is under 35 (most under 30).
From the constant 24/7 load, I imagine that both those networks are being used for P2P file sharing or media download. If they’re connected to the Internet using the building’s cable service, this might explain the bandwidth issues too. But are the high signal levels significant? Should I try to find out who owns them and ask them to reconfigure? Hard to tell.
In any case, things seem to be working well right now…..

Be careful what you wish for….

From polling Report

Theos, a new Christian think tank, heralded their launch by commissioning a poll from Communicate Research. They started by taking one of Richard Dawkins’ more confrontational statements and asking if people agreed with it: “Faith is one of the world’s great evils, comparable to the smallpox virus but harder to eradicate”…. Obviously people were going to think that “faith” was nicer than “smallpox”.
Rather surprisingly though, 42% of people said they agreed with Dawkins with only 44% disagreeing….

Atheists: The New Gays

From Scott Adam’s The Dilbert Blog:

Prior to 9/11, it would have been career suicide for a public figure to come right out and say God is a fairy tale. Now it’s a feature of popular culture…. I think the hidden benefit of Islamic extremism is that it freed the atheists from their closets. The old mindset in the United States was that almost any religion was good, and atheism was bad. But since 9/11… [ask] a deeply religious Christian if he’d rather live next to a bearded Muslim that may or may not be plotting a terror attack, or an atheist that may or may not show him how to set up a wireless network in his house. On the scale of prejudice, atheists don’t seem so bad lately.

And then he goes and spoils it all by supporting Bill Gates for POTUS….

Two terribly English films

Two weekends, two films.
Last Saturday I went to see “The Queen” up on Capitol Hill. When I told my mother about it the next day, she was incredulous: how could Helen Mirren play Liz? She looks nothing like her! Well, all I can say is that it worked. Helen Mirren was wonderful, and after a few minutes I was quite happy to accept that she was the character she was playing. The key was that she absolutely nailed the voice and a few obvious physical mannerisms; the rest just followed. (I imagine experimental psychologists could explain this in terms of the various and complex ways in which hominids actually recognize one another.) Even the guy playing Tony Blair was convincing, and once again it was mostly based on the voice.
Overall it was a very enjoyable and satisfying movie. I’m not sure why some American critics are gushing over it: it was good, but not great, and I can’t see it garnering any Oscars. (“The History Boys” looks much more like Oscar material; after seeing the trailer, I’m really looking forward to the film.)
Then today I read the review of the new “Casino Royale” in the New Yorker magazine, and decided that I wanted to see it. I think it was because the reviewer emphasized that this Bond was relatively true to the book, in both plot and characterization. I first read Ian Fleming around 1963-1965, when I was in my early teens. He was one of a number of authors, most notably Len Deighton and John LeCarre, who introduced me to the genre of spy fiction with a deeply flawed protagonist. (It’s become a cliche, but back then it was a gritty revelation.) The sex was a factor, of course: this was only a few years after the “Lady Chatterley” court case. And then there was the card-playing: Bond played cards, including bridge, and I was an avid bridge player.
I enjoyed the first couple of Bond movies with Sean Connery, but the later films (and, indeed, the later books) were just silly, and I didn’t bother with them. As several writers have pointed out, when directors like Tarantino upped the ante in violence, the Bond franchise simply turned into a campy parody of itself.
So this afternoon I saw the movie at the AMC downtown. And I have to report that the new Bond works for me. Yes, it’s too long: a couple of the chases should have been trimmed, and the poker game meanders a bit. But it feels like the Bond I remember from the second-hand paperbacks with the lurid covers. Daniel Craig is an excellent 007: much more convincing than Moore or Brosnan. Vesper is played by the erotically enigmatic Eva Green; if you saw her in Bertolucci’s “The Dreamers”, you’ll know what I mean. And she’s definitely not a classic Bond girl.
Both films: highly recommended.
