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.

Quote
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 30: Evolution Paradox, Ninja Cat, Wobbly Illusion

(Originally sent September 2008)

It’s Things 30, I’m 30. Isn’t that nice.

Films
If I have time, I may watch Taken, because it seems wonderfully up-front about its aim as a film – “They have taken his daughter. He will hunt them. He will find them. And he will kill them.”

IMDb: 7.8/10
RT: 50%

Last week’s puzzle
What is the difference between a duck?

One of its legs is both the same.

That’s the official answer. Now for something more serious.

This week’s puzzle
In evolution, the principle of ‘survival of the fittest’ generally means that over time only the most well-adapted versions of a species thrive, and this causes species to develop and improve over many generations. For example, Giraffe’s necks get longer, Lions become better hunters, and so on.

In humans, we look after the sick and the weak and we often have redistributive tax systems. We go to a great effort to help the ‘least fit’, in the evolutionary sense, to survive. In the context of the above, this seems incomprehensible. How did this happen?

Video
More cat video goodness – this time a cat that knows the rules of that childhood game known as ‘Red light/Green light’ in the US, ‘1,2,3 Soleil’ in France, and presumably something else in the UK that I can’t remember. The game also featured to great effect in the movie The Orphanage.

A very practical link:

An excellent site for checking the weather, as it includes how weather changes over the course of the day.

A quote / anecdote
On Saturday in Regents Park (while running a treasure hunt) I think I may been the target of an interesting pick-up strategy. A rather attractive French lady asked if I could take a photo of her, so I agreed. She sat on the grass and posed seductively and I took a sensible picture. She asked me to take another one with the camera looking down at her from above. It seemed unreasonable to say no at that point. Then she said “Now let us check the photos to see if you are a good photographer [she then checked them]… oh, you are fabulous! Now, let us go to Queen Mary’s fountain and take some more photos there.”

It was at this point I explained I was a bit busy and had other places to be. But I was impressed by the general idea. If I actually found the French accent attractive it may even have worked. Or perhaps I just have entirely the wrong end of a very long stick.

Things 89: Human Towers, Retroactive Prayer, Local Universe Map

Trailer
I saw Monsters at the Edinburgh International Film Festival, and it’s now on general release. As I said back in my big EIFF review post:

What: Low budget yet well-realised alien invasion as setting for semi-romantic road movie
Good: Beautifully shot, atmospheric, with an incredibly realistic-feel for its budget and a beautifully understated soundtrack from Jon Hopkins. And giant alien octopi.
Bad: Weakness in the development of the female character betrays a male gaze bias, undermining the main dynamic of the film
Conclusion: Essential viewing for anyone interested in what can be achieved on a budget, giant alien octopi, or Whitney Able’s legs

Trailer:

Video
Human Towers, some of which alarmingly do fall down:

Quote
Martin Bland, paraphrased by Peter Norvig in an excellent article on the shortcomings of evidence for prayer healing:

An ethical study proving the efficacy of retroactive prayer is logically impossible.

Puzzle
Since physical attractiveness has at least some part to play in our evolution, why does the perceived attractiveness of any given individual vary so much depending on who you ask?

Picture
I had previously wondered what the ‘local’ area of the universe looked like, for varying values of ‘local’, but some idle Googling didn’t produce an answer at the time. Just recently I came across a really nice image on Wikipedia giving the answer across some interesting different scales. Check out the file on Wikipedia, where you can also download a 7MB, not-very-compressed jpg of the image. (If that’s gone for some reason I’ve put a slightly more compressed version (2.5MB) of the image here).

Here’s a snapshot of just part of it:

Last Week’s Puzzle
Last week I asked why bedsprings make a ‘pyoing’ noise out of nowhere. Either this was too easy, too hard, or no one had any idea what I was talking about, because nobody had an answer. Consequently I turned to my not-very-secret research alter ego and asked the internet, as I did before on the shampoo question. The internet said springs get squinched down sometimes and will later pop back up. If that was the case, I would expect to usually hear these noises very soon after getting off a bed, with just a few rare occasions when it was released later. I remain unsure.

Things 29: Love Talk, Photogenic Theories, Top 10 Cats 2008

(Originally sent September 2008)

You may notice at this point that Things 30 will come out the day before I turn 30. Is this a coincidence? Or was the Things hiatus earlier this year actually very carefully planned?

Films
Still rubbish. Still not time to see them either.

A video
Here is the teaser video for my 30th birthday event:

A link
What is love? An interesting way to answer this question would be to create a web page that anyone online can edit, where they can add their opinion. Unfortunately this is not how Wikipedia is supposed to be used. Fortunately, this is how the talk page on Love *is* used, and it’s well worth a browse.

A quote
I overhead this on the street the other day:

“Fffffffffit! Fuckin’ fit, man. They are the fittest in all of South East Asia.”

The implication being that this man has assessed the fitness of not only all groups in South East Asia, but also those in the North East, North West, and South West as well. Impressive!

Last week’s puzzle
On the topic of being photogenic, I received a few replies. Xuan suggested people look different in 2D and 3D. Sian suggested that it’s actually about being comfortable with cameras, and non-photogenic people freeze up around them. This is similar to theories I have read that our perception of people is surprisingly dependent on their movements, so when we see them static it is quite different. Suzanne took this theory further by suggesting that photogenic people might be those that don’t have particularly animated faces.

In this case Yahoo Answers is very little help – but the Wikipedia page, on the other hand, is quite good, and covers some of the above theories:

I would personally add that the focal length of most cameras is not the same as that of the human eye, which can cause some subtle effects. I also once heard a great quote from a professional photographer – he said that “Women with strong character come across better in a photo when they don’t smile.” I think this is true. But do note that I don’t believe this implies the converse, which would be that women that come across well when they smile don’t have strong character!

Finally, Suzanne points out that beauty is either in the eye of the beholder; skin deep; or comes from within.

This week’s puzzle
Puzzles have been a bit serious lately so it’s time for something silly.
What is the difference between a duck?

I’ve seen a lot of lolcats since I posted a top 10 at Christmas last year. Here’s my top 10 of the ones I have seen between then and now.
