Thursday, 2010-10-14; Dubrovnik and the War

IMG_3796

I eventually head out, despite the rain. I made my way upward, partially at least. The view was still magnificent and beautiful. I'm really glad I came here. I can't imagine how breathtaking it must be when the weather is actually nice. I'm amazed at how poorly most of the photos I've seen depict the landscape, showing just a cluttered red-roofed Old Town, which doesn't do justice to the majesty of it at all. I'm glad I took the path I did: as I wrote to Bojana, as I travel down the coast, each place is more beautiful than the last. But unfortunately with crappier weather and more full of tourists.

I had another chat with Mike[1] while I was using the computer out in the hall. This time about QE[2] and inflation. He had what I thought were kind of nutty ideas that inflation was good and that it's just numbers and it doesn't matter.[3] I thought it was quite bizarre; reminiscent of that chat with Denis in Murmansk.

Speaking of money, now I can see from my cheapest month of $xxxxxxx that I am going to be spending quite a lot to make it to January, especially since this was the cheap part. I don’t know that I can sustain two or three months in Western Europe especially with the dollar in the tank against the Euro. Hrm.

I had more crappy bakery lunch, and then saw a sign for a photo exhibition about the war. It was 30 kuna[4] which I thought was a bit steep, but whatever. It was pretty terribly set up, in my opinion. The photos lacked captions; each group had miniatures of many of the photos with descriptions (but in different groups from the full-sized). So it was impossible to see the picture and its description right there. I wonder if it wasn't the point, but I found it frustrating.

I was dismayed that at first it appeared to be just one floor, and that exhibit was about the Afghanistan war. It was a grim reminder at how the country had been shit all over by international interference. And another reminder about things raised in нити[5], I mean these are just regular people born into a terrible position from which they probably cannot ever escape. Like at этажи (photo exhibit we'd visited in St. Petersburg, with more war photos), a reminder of what a god-awful place the world is, as I'm simultaneously reminded of its beauty by my surroundings.

But on the next floor, there were—in addition to more middle-eastern stuff—photos from the Balkan wars.

Wednesday, 2010-10-13; Psychology in Dubrovnik

IMG_3673

So today I'm off to Dubrovnik. I took far longer to get ready than I should have, but I made it to the bus station and bought the ticket without issue. It's a shame I didn't make it to Brač (a nearby island to Split, the town where I was just coming from), but oh well.

I continued thinking about psychology on the bus.

I wonder if prosopagnosics are able to see the triangle in the gestalt demo with three pac-man shaped circles[1], and whether they have trouble with other similar optical illusions (two arrows of the same length pointing in and out) and mental rotation. Could they be better at "spot the difference"-type things?

Tuesday, 2010-10-12 (Part II); Prelude

So, I may have stopped publishing for a while, but I didn’t stop writing.  Years go by quickly, alas.


I finished the "My Brilliant Brain" series. It confirmed what I already concluded long ago. There was a chess grandmaster that recognized games the same way most recognize faces. The fusiform "face recognition" area was equally active. I always assumed that things are more generalized and it's just specific training. I bet language involves similar intuition abilities in the auditory area, and that musical virtuosos have lots of overlap with language. I think Skinner was partially right, but it's not direct copies of input, but rather the intuitive sense of correctness and incorrectness that results from combinations of input. There is a critical period for everything. I have similar intuition about computers, but I wonder where it's manifested. The same is undoubtedly true for spelling: my voracious reading was certainly responsible for all that. It's the same with everything, what patterns have you been exposed and paid attention to, and how it gives you "intuition" which is simply the predictive activation framework described in On Intelligence. All this was exposited in Blink to some degree.

Anyway I theorized that prosopagnosia (face-blindness) is a general defect of visual gestalt. Sure enough:

A patient with severe, lasting prosopagnosia could not get an immediate overview of a face sufficiently specific for successful identification. He also failed completely in tasks of visual closure despite adequate performances on numerous other tests of visual perception and memory. We conclude that prosopagnosia represents a loss of visual “configural processing”—a learned skill enabling immediate identification of individual members of a class without conscious visuospatial analysis or remembering. Prosopagnosia and agnosic alexia represent two distinct defects of configural processing: Alexics cannot identify items with distinctive features that are themselves identifiable. Prosopagnosics cannot identify objects whose critical distinguishing features have no independent identities.

The Quantum Moment

2012’s NYI included a seminar on the metaphors of quantum physics.  Why are quantum physics metaphors (like Schrodinger’s Cat, Heisenberg’s Uncertainty Principle, Parallel Worlds) surprisingly common, more than you’d expect since quantum physics is relatively obscure subject matter for the public at large?  This is the question we tried to tackle with Robert Crease, the author of a book on this, called The Quantum Moment.

This post is background for another post on Uncertainty and Relationships. 


Perhaps one of the most surprising findings in quantum physics is from the so-called double-slit experiment.  Understanding the results will alter your entire understanding of reality.

If you’re not familiar with it, an illustrated explanation is here.  Very briefly, if you shine a laser at a card with two parallel slits cut in it, you would expect to see two corresponding lines of light behind it (say, on a piece of paper), representing the two lines cut in the card. 

But what you actually get is a pattern of interference: packets of light going through one slit interfere with the ones going through the other slit (and vice versa), and so you get multiple bands of dark and light, where they cancel each other out or add on to each other.  So the light behaves not like “particles” (each going through its own slit) but like “waves” (like ripples from a rock dropped in a pond).

Where things start blowing your mind is that this happens even if you shine only one packet of light at a time: that one packet goes through both slits and interferes with itself! 

However, if you try to be clever and add a detector, to find out which slit the light goes through before it goes through the slits, this stops happening and you get the two lines of light that you would have expected originally. 

The upshot is this: until you observe the packet of energy, it is in all places at once (with varying probabilities).  Then it interacts with something else, and of all the possibilities one ends up being the case.  This is the case for everything, not just packets of light!  Remember high-school chemistry, where the electrons orbit the nucleus at certain levels?  In some sense, each electron is in all places in that orbit at once (remember the “electron cloud”?).


This forms the basis of the Schrodinger’s Cat thought experiment: a cat is in a closed box with an apparatus that might kill it (with 50% probability).  In some sense, until you open the box to check what happened, the cat is simultaneously alive and dead.

One of the questions we were to answer:

"[W]hy does the image [of Schrodinger’s cat] still seem as packed with creative force as ever?"

Finally Sharing Pictures on Flickr!

I've decided to start publishing most of my pictures on Flickr - actually, I decided that a long time ago, but I take a while to follow through on things.  I had previously been posting them all on Facebook, but most of them have broader appeal, so I want to put those on Flickr and keep the "college antics" ones on Facebook.  I do eventually want to relocate previous ones, but one step at a time - and so, that first step is a set of pictures from a hiking trip that I went on in mid-June with a bunch of friends from the New Orleans trip.

http://www.flickr.com/photos/marksowul/sets/72157602708557423/

Enjoy!

http://www.flickr.com/photos/marksowul is my Flickr homepage.

 

PS: Kudos to Microsoft's free Live Suite; Live Photo Gallery lets you publish your pictures straight from the program.  That was a big help in actually starting to do this, since I have most of my pictures tagged and captioned here, albeit in Photoshop Elements, and duplicating this effort each time I wanted to upload pictures was a major deterrent to doing so.

Another thumbs-up for Live Writer, which lets you blog entries with ease, including adding pictures, categories, etc.  Thumbs half-down for Word 2007, which only offers basic integration with Blogger.com - in particular, no images and no categories.  So I have to choose between Word's superior offline feature set (proofing, etc) or Live Writer's online feature set.

Maybe someday Microsoft will stop reinventing the wheel (for example - the Zune doesn't use Windows Media Player, but rather reinvents it with different features, and that means you would need to keep two libraries.  Fun!  I have to admit though, I am far more impressed with Zune v2, and am also surprised that they are upgrading the features of v1 as well.  Maybe I'll write about that another day.)

9/13/2007 - The Trip to Budapest

I had been thinking about whether to take the day trips to Budapest and/or Bratislava, and in the end decided to do just the trip to Budapest. If I'd had more time, I'd have gone to Bratislava as well, but I didn't want to spend half of my would-be time in Vienna going elsewhere, since Vienna was so nice. Next time, perhaps. : )

The trip was terrific. It took about two hours to reach Budapest by bus. It was a nice ride, and we passed by the Hungarian city of Tatabánya, which is home to the "Turul" monument, which is the mythical bird of the Magyars' (Hungarian people's) origin myth. It is the largest bird statue in Central Europe, but to me, it was fairly unimpressive from our vantage point.

When we reached Budapest, we had a short bus tour through the city, and then lunch. It was beautiful, though I learned that 70% of it had been leveled during World War II. In contrast to Austria (which had also been widely damaged, evidently), the country was not rich enough to instantly rebuild it, so it was, in many places, still run down.

At lunch it was as though I was back in America; we were eating at a restaurant in a Best Western (Hungarian food though), and I was at a table talking with a couple from California and a woman from Phoenix. We talked about various things, including travel, and then the whole real-estate crisis. Needless to say, I ended up telling my story, and then the couple from California was talking about theirs; they had traveled a lot, and had been to a few different places on this trip, including having taken the day-tour to Prague the previous day. They said they preferred to see things in depth, and so on a two-week vacation they might see only one or two cities, because they wanted to really experience them and remember them and so forth – I didn't quite understand how that philosophy fit together with their taking these one-day trips to Prague and Budapest. The topic shifted to the real-estate stuff in the US, and they said they were not shedding any tears about the realtors, as they went through some of their bad experiences (they've moved seven times), though I kind of lost interest.

After lunch, we subsequently went on a walking tour through the city. There was a Russian couple (living in the US) with whom I chatted briefly; I had heard them ask the guide whether she'd ever been to any of a few ex-Soviet countries they named (Kazakhstan, Uzbekistan, etc). Consequently, I wondered whether they were Russian, and then heard them speaking to each other. Another element of Russia that was strange to see here were Russian nesting dolls as souvenirs. I didn't quite understand what they had to do with anything here. Apparently someone else raised a similar question or the guide read my mind, because I overheard her say that they were Hungarian-made, which she imagined might have been the point; she too disagreed with selling them there since they had no relevance to local culture, but admitted that they were popular souvenirs, so it benefits them in the economic sense. Shrug. The ironic thing is that this "traditional symbol of Russia" was actually brought there by the Japanese.

After the walking tour, we then had some free time (two hours or so); I went up to the cupola of St. Stephen's Basilica, offering a great view of the city, and then walked around "Andrassy Street", one of the main pedestrian boulevards. I indeed ended up making it to Budapest after all, although I regretted the almost uselessly short amount of time, although between the walking tour and the free time, I did get to see a lot of the city.

On the way home, I talked at length with a man from Singapore. I hadn't realized English was the native language there, as he did have what I would consider an accent. He was a real estate lawyer who was on a 2-week vacation; he had succeeded where I hadn't, arriving in Italy and seeing two or three cities there (Milan, Venice, and Florence maybe) by train before taking the train to Vienna, playing it by ear. He gave me his card, telling me to let him know if I ended up traveling to Singapore someday. Ironically, earlier in the day, the man from California had said Asia was a lot of fun, except for Singapore. Hm. Guess I'll have to see for myself.

Anyway, he also helpfully reminded me (as have others along the way) that this is an opportunity I won't see again once I start working full time – yeah, I'm acutely aware of that (thus visions of sugarplums and teaching or the Foreign Service dance in my head). Черт знает.

He also was telling me of some of Singapore's draconian laws, among them being caned for vandalism – I have little sympathy for this; vandalism is a crime that benefits no one and is just a big nuisance. Another one is being hanged for drug trafficking. Wow.

We talked about music a bit also. He had ended up buying 20 books (many were thin; it was a few small bags) at a store and remarked at how gloomy and unfriendly the staff was. I remarked at how friendly Vienna seemed, and he agreed, but said he hadn't had the same level of friendliness that I had, encountering some less helpful people in the train station information office, and his first night's hotel.

In Budapest, there is a "6-star" hotel, the Four Seasons. We wondered about this, and then wondered what the point is, since if you're traveling somewhere you're usually only in the hotel for a few hours a day, mainly to sleep – as long as the hotel is nice enough and close enough, why pay thousands a night?

He had bought some food (there was lunch on our trip, but not dinner) and gave me some, as he'd bought too much for himself. It was a slice of pizza with peppers, corn, and other flora non grata embedded in it, so I "saved it for later" and tried to eat around the vegetables before just tossing it. So it goes. I met the first bum/beggar I'd seen as I walked around before returning to my hotel. I was relieved as I pulled out a bit of change (to "feed his dog"), that I had succeeded in not grabbing any full Euro/two-Euro coins. On that note, those Euro coins are a psychological menace, because it's very easy to spend some "spare change" that amounts to several dollars!

10/1/2007 – Scott Adams Predicts the News

I have in fact come home, but I have been too busy at the moment to catch up with writing entries about my trip. Nevertheless, I saw the following and had to share it:

Scott Adams describing the news (http://dilbertblog.typepad.com/the_dilbert_blog/2007/08/synchronicity.html):

"Indeed, all of the news is nothing but basic stories with randomized features. Watch as I predict tomorrow's headlines today:

EXTREME WEATHER BATTERS SOMEPLACE
IDIOTS KILL INNOCENT PEOPLE
POLITICIAN DOES SOMETHING ILLEGAL
PRIMATE ATTEMPTS INAPPROPRIATE SEX
EXPERTS WARN OF FINANCIAL CALAMITY
BIG COMPANY BUYS ANOTHER BIG COMPANY
FAMOUS PERSON DOES SOMETHING INTERESTING
A SCIENTIFIC DISCOVERY MIGHT BE USEFUL IN TEN YEARS
GOVERNMENT FAILS TO ACHIEVE A GOAL"

(NB: Scott Adams proposes that, "As regular readers of [his] blog know, all coincidences are clues that we are holograms programmed by our long dead ancestors before the planet was annihilated.")

This was amusing because the same formula seems to apply internationally as well (I thought it was just the U.S. that had shallow obsessions with irrelevant "newsworthy" figures, but Europe is quite obsessed with Madeleine McCann in the same exact "JonBenet Ramsey" kind of way. And even if there is real news on the case, that's no excuse not to indulge in baseless speculation! Ugh.)

The other day (ok, last week in fact), I went into the city [i.e. Manhattan] to hang out with some of my Stony Brook friends. One might think that, having had to deal with several different foreign subways in other languages, the NYC subway system would be a piece of cake. Nope. It's significantly more complex, even more so than that of Moscow (map). I took an "express" train instead of a "local" and thus missed my stop and had to backtrack, wherein I had to wait nearly twenty minutes for another train (apparently there was construction) since the first one that came did not match the platform. (The express was an A train, the local was a C train – I was waiting at the C platform, but an A train came, and not sure which to believe, I waited for a second train to be sure).

The finicky metro cards are a fairly terrible design. There is always a huge funnel of people trying to go through the turnstiles, and it seems that there's about a one-in-a-million chance of the reader actually working on the first (or even second) swipe. The other subways that had electronic cards sucked in the ticket and spit it back out, which always worked the first time (unless it was invalid). The better of those sucked in the ticket at the front, and then spit it out at the actual turnstile just as you approached it. The voices on the trains were automated (and thus audible), instead of mumbling gibberish, and in many cases there was also a visual indicator of the stops as well as where you were (as with some of the newer subway cars).

Scott Adams describes his experiences here, hilariously as always: http://dilbertblog.typepad.com/the_dilbert_blog/2007/09/new-york-city-s.html
