Things 43: Indian Superman, Pub Quiz Physics, Star Wars Collection

(Originally sent March 2009)

Video
The joy of cultural differences – Indian Superman (sound essential for when they get to the musical number):

(Note that their superman does not wear red pants on the outside – clearly they thought that would just be silly)

A link to the non-text bit of another video, also showing the joy of cultural differences – a hard-hitting realistic portrayal of modern warfare featuring large-headed anthropomorphised animals, with a dramatically incongruous title:

Last Week’s Puzzle
Last week I asked how much longer a string stretched around the earth’s equator would need to be if it were to be raised by one meter (or indeed metre). Since the circumference of a circle is 2*pi*r, the new circumference would be 2*pi*(r+1) = 2*pi*r + 2*pi*1, i.e. 2*pi longer – under 7 metres.

This is counterintuitive since it seems very small, and it also doesn’t depend on what the radius of the earth is. A way to comprehend this intuitively is to imagine a square instead of a circle – to extend a string wrapped around a square of any size by one metre would always need two metres of string to be added at each corner.

Puzzle
This week: pub quiz physics. The most abundant element in the universe is Hydrogen which has 1 proton. The next most abundant is Helium with 2 protons. What is the third most abundant element in the universe?

Things 98: Weakest Link Puppets, GPS Doom, Visual Metaphors

Video
I really like The Weakest Link Puppets Special. There’s something about the way these worlds collide that just keeps me smiling as I watch – childish responses to adult questions, adult responses to childish questions, and a wonderful willingness of all concerned to make what’s ultimately one of the simplest illusions going really work. If you want to see the rest of the episode, YouTube will show you the way.

Puzzle
After last week’s question on old-stuff-on-the-internet, I was looking back at my old Geocities site (now living on my own domain after Geocities shut down) and came upon my old Alternative Newsletters. I like to think of these as precursors to the Things email, but they’re really completely different, so I probably shouldn’t.

Anyway, one of them had the following quiz, which I thought I’d adapt for Things:

1) Is the answer to this question yes?
2) Is the answer to this question no?
3) Is the answer to question 4 maybe?
4) Are most of the answers yes in this quiz?
5) Have you stopped worrying about logical yes/no question traps?
6) If you answered maybe to questions 1-5, ask yourself another question in place of this one: If you cyclically rotate ‘maybe’, ‘no’ and ‘yes’ forwards through the alphabet, then answer questions 3 and 5 again, does this change whether or not you have to answer this question?
7) Answer this question last: What is the answer to question 8?
8) Is the answer to this different in comparison with the answer to the last question?

You don’t need answers, you know how many you got right.
Scoring:
0-2 questions correct: congratulations, you could be sane.
3-5 questions correct: bonus question! Did you get more than 3 correct? Answer, mark, and re-score.
6-8 questions correct: you do not need my congratulations, getting this many correct is its own reward (and punishment)
9+ questions correct: See Me.

Last Week’s Question
Last Week I asked “What is the oldest evidence of your own activity on the internet you can still provide a live link to now”.

For me personally, it’s this review on Amazon dated 24th September 2001. I was active in a few other places before that, but they’re all dead now. Let this serve as a reminder to back up any data you hold dear.

Richard beats this by a long distance, with his usenet post dated 4th February 1992. Nearly 20 years ago! That’s a long time in the world of the internet.

By the way, the natural conclusion of this little game would be to try to find a link to the oldest thing on the internet. I’d have no idea where to begin, but let me know if you do.

Things 42: Baby Chaos, Gigapan, Energy Forecast

(Originally sent March 2009)

Movies
I saw and enjoyed Watchmen. I think having already read the graphic novel helped a lot, but it is certainly an interesting bunch of things to see on a screen in any case. Despite an unhealthy obsession with being true to the graphic novel (I personally think changes do need to be made to present a story in a different medium) the director couldn’t resist pumping up the strength of the characters, thereby undoing one of the most interesting aspects of the original, which was having superheroes that aren’t super, they’re just people who are a bit weird.

Video
A time lapse video demonstrates how babies are agents of chaos:

Link
Gigapan is a clever system for taking and knitting together photos into a zoomable panoramic image such as this one.

Quote
Last week’s quote about a dog finding a chainsaw was from Disney’s Lilo and Stitch which I highly recommend to everyone.

This week, an amusing line from Rousseau’s ‘Discourse On Inequality’:

“Savage man, when he has dined, is at peace with all nature, and the friend of all his fellow-creatures.”

Puzzle
On the subject of the body’s constituent molecules being replaced every seven years, some interesting things to consider are tattoos, memories, teeth, and ova. A proper scientific answer with real experiments and references and everything can be found here.

Now, a geometry classic: if you had a piece of string long enough to go around the earth’s equator at sea level, how much longer would it need to be if you wished it to be one meter above sea level?

Picture
Below, a rather fascinating forecast of global energy production. Had I been asked to guess, I would have thought the yellow area indicated nuclear fusion, which turns out to be conspicuous by its absence. Presumably on the basis of always being about 30 years away.

Things 97: Vertical Ship, Climbing Game, State of 3D

GIRP, a really nice little climbing game (probably easier to get to grips with if you know from the start that feet are not involved).

Question
What is the oldest evidence of your own activity on the internet you can still provide a live link to now?

Last Week’s Puzzle
Last week I asked if it was true what they say, that 3D can never work. I think there are two compelling clues towards an answer here.

First, Box Office Quant takes a good solid look at what the money in 3D cinema is looking like. The conclusion is that after two years of 3D cinema being a serious consideration, it’s looking pretty solid. There’s lot of great data and visualisation of it over on the original post, but I’ll just reproduce the weekly revenues by dimension here:

It’s clear that something is working, anyway.

On the other hand, there was this development with Nintendo’s autostereoscopic 3DS by its producer Hideki Konno:

“We want to get software out to as many people as possible, and there are some people who just can’t see 3D […] We’re moving away from any stance that says if you don’t use the 3-D functionality you can’t play this game.”

While I’m yet to see some solid data, the picture that seems to be emerging is that a significant minority (10%?) really do have an issue with the convergence/focus conflict that Walter Merch identified (and which is, incidentally, the underlying science behind the apparent paradox highlighted in this XKCD), to the point that watching a full-length 3D movie or spending a significant time playing a 3D game is an uncomfortable experience for them. Naturally there’s also a small proportion of people that for various reasons do not perceive 3D in real life, for whom a 3D film/game has nothing to offer above a 2D one (and I suspect they are being used as a kind of smoke-screen to hide the bigger concerns about the former group in Hideki Konno’s quote above).

It seems that minority is small enough that 3D cinema revenue remains robust, but large enough that Nintendo don’t want to undermine their universal appeal by allowing 3D to be a barrier to participation.

Incidentally, I find it an incredible sign of the times that we now have three dimensional full-colour moving image experiences at a fully commercial scale, which is really quite an amazingly neat trick, and yet so many people I’ve spoken to seem to feel it’s not particularly worth having. Or in Louis CK’s words, “Everything is amazing right now, and nobody’s happy”:
