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?

Picture
From Dorothy ‘Cat and Girl’ Gambrell’s visualisation site Very Small Array, the United States of Autocomplete gives Google’s autocompleted suggestion of what should come after each state name (note results are regional, we’ll get different results from the UK) (click for full size):

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 21: Trolley Problem, Hamster Gaming, Sky Font

(Originally sent July 2008)

This week’s films – one line reviews
If you like nice fluffy happy films you have to see Wall-E. If you like dark mind-bending films you have to see The Dark Knight. These are both extraordinary films that demand and deserve your attention.

Next Week’s film
I’ll be watching Mamma Mia.

I’ll be watching Dark Knight again.

One of the above is true, the other is completely ridiculous and out of the question.

A Puzzle
Inspired by the events in The Dark Knight, here is the standard “trolley problem” (where trolley actually means tram):

A trolley is running out of control down a track. In its path are 5 people who have been tied to the track by a mad philosopher. Fortunately, you can flip a switch which will lead the trolley down a different track to safety. Unfortunately, there is a single person tied to that track. Should you flip the switch?

A wonderful font. (Unfortunately this breaks the nice cute/dark dual theme this Things had going. Oh well).

Things 80: Underwater, 3D, Propeller Puzzle

Video
A simple idea, but no less amazing for it:

Read more about this here.

Link
As soon as 3D cinema started to see regular releases, many of us wondered if there was a market for designer 3D glasses, or at least nicer ones than the pairs you get at the cinema. I suspect with the advent of 3D TV using the same technology, the market becomes viable, and so the product duly emerges.

Quote
Marvellously surreal, but also interpretable as a variation on carpe diem:

Bill Murray as Phil in Groundhog day: “Well, what if there is no tomorrow? There wasn’t one today!”

Puzzle
Given that no Photoshop is involved, how was this photo achieved?

Photo credit (and by its context, answer to the puzzle) is here.

Things 17: Semiotic Blancmange, Change Blindness, Me

This week’s film – one line review
Mongol was bizarrely repetitive and dramatically failed to chart the rise of Genghis Khan as it had promised.

Next Week’s films
I’m going to see The Happening (because I like “everyone’s gone” films) and then The Incredible Hulk (because superhero movies are modern fairy tales) immediately afterwards, bringing the number of films I have seen this month to a total of 5. If interesting films continue to come out I may beat my personal best of 7 in a month, averaging £1.71 with the Cineworld Unlimited card. Woohoo!

The Happening
There are so many trailers for this that I think I’ve put together everything, but here’s a good one: http://www.youtube.com/watch?v=kxMLvh4Tb6g [gone, oh well – T.M. 7/11/14]
IMDb rating: 6.8
Rotten tomatoes rating: 11%!!

The Incredible Hulk
Trailer that seems to sum up the entire movie: http://www.youtube.com/watch?v=E7a5LcTckfg
IMDb rating: n/a
Rotten tomatoes rating: 71%

Last Week’s Puzzle
The two main differences between memes and genes that we identified were that memes never really ‘die’ so can produce offspring indefinitely afterwards (note for example that many email scams were in existence in letter form over a century ago); but also that they actually evolve by Lamarckian evolution rather than Darwinian:

This Week’s Puzzle
What comes next?
person, fiddle, degree, estate, column, sense, ?, …

A Quote
The descriptions in Photoshop Disasters are often very well written.

“By renormalizing the model’s waistline, Maxim Mexico takes a bold socio-political stance in the ongoing battle of the politics of representation, clearly referencing the oppressive reification of male-gaze heteronormative modes of synthesis in a semiotic blancmange of post-structural teakettle barbecue hatstand fishmonger.”

To continue the illusion theme, I encourage you to try out this excellent java application demonstrating the incredible effect of change blindness.

Two images cycle with a flash between them: the challenge is to spot what is different between the two images. When you give up, right-click on the image and set the ‘delay’ to be shorter – when you get down to ‘no gap’, the change becomes completely obvious. Then use the right click menu to reset the gap length to a challenging amount (very important – if you watch a different image with ‘no gap’ the difference will be obvious and you can never un-see it), then try a different image.

If anything, this is more incredible than the video last week.
