Things 90: Inception Diagram, Clay Shirky on Wikileaks, United States of Autocomplete

Tim Link
After a lot of research and a second viewing with a lot of note-taking, I felt like I had got to the bottom of Inception. My diagram and explanation of what I think is really going on can be found on Tower of the Octopus.

Link
Clay Shirky’s view of the Wikileaks situation seems much more balanced and reasonable than anything else I’ve read on it.

Also, see the Wikipedia article on the Streisand Effect.

I can’t actually find who said this first on Twitter:

Pissing off 4chan: free. Botnet hire: $1000/month. For everything else, there’s Mast– oh, wait, not any more there isn’t.

Puzzle
We are told that your ears go ‘pop’ in a plane after take-off because of the air pressure changing with altitude. But we also know that the cabin has to be airtight, as if air could get out the pressure would equalise and above 17,000 feet everyone would die. So why does the air pressure change in the cabin at all?

Last Week’s Puzzle
Last week I asked “why does the perceived attractiveness of any given individual vary so much depending on who you ask?”, which provoked quite a bit of discussion on the CC list.

Thomas points out:

It’s not enough for both parents to have ‘good” genes, but they should have “good” genes that are sufficiently different that any child will have the maximum possible genetic advantages.

Or as Xuan put it:

Attractiveness: Relative to your genes and where you want them to go.

Simon adds a practical consideration:

… people of similar levels of attractiveness find each other attractive (because your genes have the best chance of survival if you can maximise some function of beauty x propensity to shag me)

Phil counters:

So many couples look very similar though! Perhaps that is somewhat due to acquired mannerisms, but I’d have thought there’s a strong trend to find people similar to yourself attractive, to help similar genes survive

My summary of the situation was this:

To have the best chance of promoting themselves, your genes want to help others with similar genes (and procreating with them is pretty helpful), but also combine themselves with complementary genes. With both of these pressures in effect, and a distorting lens of nurture on top of the nature, we can’t be too surprised that people disagree on attractiveness.

Finally, Matt raises the logical next question – how to genes actually do this:

I think we may be giving too much credit to genes abilites to recognise similar genes and indeed complementary genes here. And after all, there are a lot of different genes with a vested interest here. I would posit that we decide who would be a good catch based on a set of genes (and so on) that try to recognise success in any form – one of the primary indicators surely being perceived social standing, but also apparent health, virility etc. So, regardless of precise genes, recognising good stuff.
I find the idea of encoding a DNA sequence that will give rise to a brain that will perceive the outside world and detect optimal reproductive opportunities almost completely mindboggling.

Things 85: Talking Cats, Shark Facts, 285 trends

Video
Bowing to the inevitability of Moore’s law, cats with captions are no longer as popular, instead being replaced by dubbed videos of cats. Lip-syncing and attitude-matching are key:

Links
I recently discovered that Sharks can sense electricity! And are also viviparous, despite not being mammals! These things should really be taught from an early age. If you didn’t know those things, do follow those links and fill in this shocking gap in our educational system.

Quote
On Luke’s Facebook profile under ‘quotes’, he writes:

I am not big on quotes, as I think proper arguments take more than a few lines to construct. Quotes are therefore like mantras – declarations of universal truths which I am naturally rather suspicious of.

To further undermine this entire section of Things, I was recently reminded of David Malki’s thoughts on the matter; he also monetised the idea by producing a suitable bumper sticker. A banner on the same basis was the kind of thing likely to be seen at the Rally to Restore Sanity.

Puzzle
After recently trying to convince people that the number 285 occurs more often than it should (a perennial hobby of mine), I re-ran the numbers on search volumes and found something rather strange. What is going on around August here?

Last week’s Puzzle
Last week I asked how one might devise an experiment to test for the existence of Free Will, using “any definition of Free Will you think might be useful” (since an experiment reported in the Telegraph seemed obviously lacking).

John cited far more interesting MRI experiments which strongly suggest ‘decisions’ are made up to 10 seconds before we are consciously aware of them. But I felt that the nebulous concept of Free Will could also dodge this attack; perhaps Free Will ‘happens’ before that decision process becomes visible to MRI and before we become aware of it. There are plenty of other experiments that demonstrate that a lot of strange processes conspire to construct the illusion that we are experiencing the world in ‘real time’, but that’s another story.

Tarim said he couldn’t think of any definition for Free Will, which is a pretty reasonable response. I admitted I had personally found considering the ‘devise a test’ question a useful line of thought for clarifying the matter in my own mind, but just trying to come up with a definition is actually a more direct route.

This being the internet, we don’t have to look too far to find people trying to give definitions of Free Will. It actually seems fairly straightforward: it can either be used in a ‘Compatibilist‘ sense, or in a sense that doesn’t make any sense.

Angela (who also noted the definition problem) said she would ask her solicitor, who apparently offers a free will service.

Finally, I note that Things 66 (sent just before I started blogging each edition) included this link on the subject.

Things 84: Sleep or Draw, Free Will Test, Ursa Magus

Tim Link
I’d like to get better at drawing, and I know the best way to do that is to draw every day. But previous attempts to form this habit always run out of steam. My new plan is to post each drawing on Tumblr, and also to tell people that I am doing so (so you reading this is an integral part of the plan). Even if nobody ever follows that feed, the fact I’ve published it theoretically creates the sense of accountability I need. I’m also very impressed at how good Tumblr is at streamlining the publishing process, and highly recommend it for this kind of endeavour:

Sleep or Draw

Despite familiarity with Google Streetview, being presented with random locations on earth by this site does feel strangely magical.

Observed on Facebook:

Commenter: “People do give a damn but most can’t be assed to show their support”
Profilee: “Well then they don’t give enough of a damn for it to be worth a damn.”
Commenter: “Damn!”

Puzzle
I was fascinated to read an article in the Daily Telegraph which suggested that the fact you can artificially create a stimulus in someone’s brain that will cause them to make a physical movement somehow proved that Free Will does not exist. Whatever you might think about Free Will, it seems pretty clear that being able to get some kind of effect by one method doesn’t exclude the possibility that a different method could still provoke the same effect, so the leap to ruling our Free Will seems premature.

Still, I think there’s an instructive puzzle here: given an arbitrary budget, and any science-fiction technology you care to imagine, how would you devise a test to see if Free Will exists? Feel free to use any definition of Free Will you think might be useful.

I tested this game (from Loldwell.com) with a friend while stuck on a delayed tube train. I recommend it.

Previous Week’s Puzzles
In Things 82 I asked why street lights weren’t at least partially solar powered, and in Things 83 I gave some guesses. Richard pointed out that since both street lamps and council buildings are already connected to the grid, any effort in this area would be better spent on the latter, where solar panels would be far easier to deploy and maintain.

He also notes that:

The street furniture I’ve seen with solar/wind panels tends to be speeding signs in rural areas, where the sign is only illuminated occasionally, appears to be LEDs, where a connection to the grid might be costly, and where a power failure would not be inconvenient.

Russell points out that the Mars rover proved more resilient to sand build-up than originally expected because the Martian wind did a good job of keeping the panels clean (so bolstering the potential of the solar-powered street lamps I originally linked to); he also links to the appealing prospect of solar-energy-harnessing paint.

Then, in Things 83 I asked why fingers wrinkle in water and the rest of your skin doesn’t. Russell noted that from his diving experience he knew for a fact that your palms will also eventually go wrinkly after an hour or two, and attributed this to surface-area:volume ratio differences.

The internet tells me that the first barrier to the water is the layer of sebum, and only once that is washed away can the water get in and wrinkle the skin. An unknown internet person claims the finger tips have the least sebum, so are first to wrinkle. However, the first link (which sounds pretty authoritative) also claims that “no one is really sure” exactly what drives the wrinkling process, and wikipedia cites a paper which claims sebum “may serve little or no purpose in modern humans,” so it seems as if the whole thing remains somewhat mysterious.

There’s also a deeper question behind these answers: is this wrinkling thing a Bug or a Feature of our skin, or to put it another way, did it evolve for a reason? Being a fan of the (heftily discredited) Aquatic Ape Hypothesis, I like to imagine it’s actually a feature designed to improve grip when we’re in the water, an idea which presumably could be tested with some kind of gripping experiment, which I may at some point try to carry out.

Things 23: Google Trends, Talking Pets, Growing Beard

(Originally sent August 2008)

This week’s colon-heavy sequels
X-Files: I Want To Believe: Only for hard-core X-Files continuity-followers, does not warrant a big screen.

Hellboy II: The Golden Army: Great example of how to do a ridiculous and silly film that leaves the audience smiling.

The Mummy: Tomb of the Dragon Emperor: Great example of how to do a ridiculous and silly film that leaves an audience feeling they wasted their time and money.

Next Week’s films
Next week I may take myself to see Space Chimps, purely because I heard that the second half goes crazy psychedelic and makes no sense, which is often a good sign.

IMDb: 3.7/10, RT: 34%.

Er… perhaps not then.

A Puzzle
Google Trends shows search volume over time, which is often fascinating. For example, we can see that in the eternal battle between pirate and ninja, 2004 was a key turning point.

http://www.google.com/trends?q=pirate%2C+ninja&ctab=0&geo=GB&geor=all&date=all&sort=0

You can also use it to track the popularity of different things rather well. For example, the decline of the wrist watch as mobile phones render them redundant:

http://www.google.com/trends?q=wrist+watch&ctab=0&geo=all&date=all&sort=0

Given all this, how do you explain the following apparent decline?
