Things 47: Flying Robot Penguins, Hamster Wheel Projection, Space Stick

(Originally sent May 2009)

Film
I saw Wolverine. I found it to be acceptable. I was particularly impressed that they held almost all shots of the enjoyably over-the-top climactic battle back from the trailer.

Video
In this video there are giant flying robot penguins, after the small swimming robot penguins, after the pre-roll ad, after the video loads. But worth the wait.

Since the media make it very difficult to tell if a manageable disease outbreak has grown into a rampant society-threatening pandemic of doom, here’s a map that collects data on the progress of Swine Flue cases.

Semiotically speaking, the size of the circles when zoomed out subconsciously suggests a more severe situation than is actually the case, but zooming in quickly brings things into perspective.

Quotes
Going through my old archive of things-I-heard-people-say-and-wrote-down recently, I found a cluster of baffling utterances all made by the same individual, who shall remain nickless. Er, I mean nameless.

“I’ll take your word for it – but I’m still not convinced.”

“Is it one of those things you can only see when you look at it?”

“I don’t like shopping, it’s really boring. Except when you’re buying something for yourself… or someone else.”

Picture
I’ve come across this three times this week, but feel compelled to add to its viral propagation. Here and There is a “horizonless projection” map of Manhattan, which some have more intuitively described as a “hamster wheel projection”.

Previous Puzzle – The Inconvenient Hobby

Last time I asked for a time-based goal that can easily become part of a routine but sits somewhere between once-a-day and once-a-week. Given some of the answers, it became clear I hadn’t emphasised the ‘easy’ part sufficiently!

One answer was to tie different aspects of the same goal to different days of the week For example, if the goal is to exercise 3 times a week then one could do three activities once a week each, assigning each one to a particular day of the week.

My own answer has been to create a spreadsheet which automatically pops up when I boot up my PC and tells me how many days have elapsed since I last did the six things I’m trying to do with non-trivial frequencies, and whether that exceeds my target number of days to elapse for each one. Or at least, that will be my solution, but I haven’t got around to implementing it yet, which perhaps speaks to a greater problem.

Puzzle – the Space Stick
Information cannot travel faster than the speed of light. If it did, you just need to apply a bit of special relativity (not even general relativity) and you quickly get paradoxes. There’s a deeper argument to be made there, but trust me, if information could travel faster than the speed of light, It Would Be Bad, in the Ghostbustersian sense.

(Side note: that link was an example of something Kevin Kelly has spoken about – bringing the tools we have for literacy (cut and paste, footnoting, referencing) to moving pictures. Unfortunately the audio is very quiet on the YouTube video I linked to so it probably doesn’t quite work, but it’s close. See http://kk.org/ct2/2008/06/tools-for-vizuality.php )

[We now see further problems interfering as the video has been taken down. It linked to the utterance of the phrase “that would be bad” in Ghostbusters. – T.M. 30/4/11]

Unfortunately this important speed limit on information transfer seems to break if you have an extremely long stick.

It’s difficult to state the problem both precisely and concisely, but here we go:

Imagine you are at one point in space and your friend is one light-year away. You are about to have a baby and your friend will want to know if it is a boy or a girl as soon as possible. If you were to send this message at the speed of light, which is incredibly fast, it would still take one year for the message to reach them, since you are one light-year apart.

Anticipating this issue, you have got hold of a Space Stick, which is one light-year long and as rigid and low-mass as a substance can possibly be. With the Space Stick spanning the distance between you and your friend, you arrange for it to sit above a button that activates a buzzer at their end, the idea being that you simply press on your end of the Space Stick and the button is pressed pretty much instantaneously.

With a pre-arranged code (tap for a boy, long press for a girl) it seems as if this could be used to transmit information faster than light. Why could it never work?

Things 100: Spaceship Earth, Fake Hacking, List, Scientific Method, Owlbears

It’s Things 100. Time for some particularly epic Things.

Video
I remember reading (in Critical Path, lent to me by John) that Buckminster-Fuller felt it was very difficult to watch a sunset or sunrise and intuitively apprehend that what you see is due to the earth turning – but that if we could succeed at doing so, we would come to better appreciate our place in the universe, and perhaps make wiser long-term decisions.

Even though I’ve seen plenty of night-sky time-lapse before, for some reason this video is the first I’ve seen that really gives me that feeling:

The Mountain from TSO Photography on Vimeo.

Link
A while ago I thought it would be neat to make a program that took as input random keyboard mashing and produced as output  the appearance that you were doing some movie-style hacking, complete with big secret-service logos and password fields that flash up “ACCESS DENIED”, “ACCESS DENIED” and then “ACCESS GRANTED”, and obviously lines and lines of clever-looking code, but I didn’t have the know-how to make it happen.

Fortunately, the internet provides – it doesn’t do the whole window thing I imagined, but you do get to mash the keyboard while apparently producing reams of commented hacking-type code (none of which I understand). If you want a version that also makes bleeping noises for no reason, just like in the movies, you can use this one instead.

Tim Link
I blogged my responses to the first 10 questions in the “30 Days of Video Games Meme”. Probably worth reading if you’re interested in games, or in gamers, or the formative life experiences of me.

Quote kind of thing
Diving back into my own archive, I was quite pleased with this list of self-referential things I collected and created on my old Geocities self-referential page:

Imagine a world with no hypothetical situations.
This sentence has cabbage six words
There are no redundant redundant words in this sentence.
This statement is false
This statement is not provable by me. (Useful illustration of Godel’s incompleteness theorem)
The smallest number that cannot be stated in fewer than 22 syllables
Consider the set of all sets that have not yet been considered.
Mispeltt
Ptyo
Repetition
sdrawkcaB
The ‘pre’ in prefix
Quinquesyllabic
Self-referential
Word
Ineffable
Recherche
Sesquipedalian
Non-phonetic
Illiterate illiteration
“All clichés should be avoided like the plague” (attributed to Arthur Christiansen, found in “The Joy of Clichés” by Nigel Rees)
This is not the last example on the list.
Inelegantness
Pseudo-Greek
Aibohphobia (credited to Imre Leader, although the Wikipedia cites the Wizard of Id)
Grammar message in Microsoft Word: “This may not be a complete sentence”
TLA
Abbr.
This sentence contains three a’s, three c’s, two d’s, twenty seven e’s, four f’s, two g’s, ten h’s, eight i’s, thirteen n’s, six o’s, ten r’s, twenty fives’s, twenty three t’s, three u’s, three v’s, six w’s, three x’s, and four y’s.
In order to understand the theory of recursion, one must first understand the theory of recursion.
I don’t speak English (Je ne parle pas Francais, etc…)
Stretching a metaphor to breaking point, then snapping it, shredding it into small pieces and mashing them into a pulp.
Adjectival
Illegitimate
There are 3 kinds of people in the world; those that can count, and those that can’t.
Actually, there are 10 kinds of people in the world; those that can count in binary, and those that can’t.
“a7H.4hwJ?22i” is an example of a good password.
Repetition
A rag man
Penultimate
This is the last example on the list.

Puzzle
What is going wrong with the scientific method? That’s a very long article, but it’s a very big question, so worth a read and a ponder. (And hey, this is Things 100 after all.)

Picture
And finally… what do Owlbears look like? The ArtOrder asked, and a bunch of different artists came up with a really fantastic range of answers.

Things 46: Miniatur Wunderland, Map of Remoteness, Door Considerations

(Originally sent April 2009)

Video
Brought to my attention by Richard, the official corporate video of ‘Miniatur Wunderland’, the largest model railway in the world, complete with earnest German-accented voice-over:

http://www.youtube.com/watch?v=PN_oDdGmKyA

Link
An article on New Scientist with some great images showing the extent of rail, road and river networks across the globe, and the resultant ‘remoteness’ score for any given location.

Quote
I’ve mentioned this quote in conversation about three times in the last two weeks so it’s evidently topical:

Don Marquis: “The chief obstacle to the progress of the human race is the human race”

Puzzle
Last week I asked why front doors open outwards. If there can be said to be one true ‘reason’, it is that there are many reasons for it to be this way round and only one for it to be the other:

– Practicality. A common situation is for one person to be opening the door for another from the inside. It’s safer to have it open towards the person doing the opening.

– Security. If the hinges are on the outside they are more easily removed. It’s cheaper to have the door open inwards if you want to have the hinges inside.

– Weather. The hinges (see above) and interior of the door will tend to be less exposed to the elements if the door opens inwards.

– Defensibility. It’s easier (that is to say, actually possible) to defend against a potential intruder by barricading a door that opens inwards.

The only reason I’ve heard for going the other way is for safety in case of a panic evacuation, where people are likely to be pushing against whoever is first to the door. This trumps the other reasons when it comes to large public venues, but is not significant in an ordinary home.

This week’s puzzle
A great way to motivate oneself to do something (such as housework or a hobby, say) is to set an achievable time-based goal that can easily become part of a routine, like doing it once a day, or once a week. For example, I frequently intend to start a draw-once-a-day routine, and send Things almost weekly; others have similar goals for photography, or blogging.

The problem is, there’s a ridiculously huge difference between ‘every day’ and ‘once a week’. What possible strategy could one use that is somewhere between these two extremes?

Picture
It’s not explained very well, but apparently the European Space Agency’s “Environmental Satellite” can use radar to detect changes in the Earth’s surface with millimetre accuracy. In this way, images from before and after the recent L’Aquila earthquake in Italy can be compared to track how the ground has been shifted. It’s a pretty fascinating visualisation.

Things 45: Ant Colony Sculpture, Maunder Minimum, Photoshop Effect

(Originally sent April 2009)

Video
What happens if you fill an underground ant colony network with concrete, let it set, then excavate the resulting sculpture?

The sunspot cycle typically lasts 11 years. We are currently undergoing an abnormally long period of low (and therefore cooler) activity, still going 12.8 years after the last solar minimum, which some speculate heralds the beginning of a new Maunder Minimum. However, NASA say this is unlikely and will not have a significant effect on global warming.

I like it when you get a complete story in the few seconds of conversation you hear as you walk past someone. I overheard this:

Teenager: … and then he says-
Adult [interrupting]: “Why have you got no clothes on.” I told *you* that joke.

Last Week’s Puzzle
Last time I asked what you could buy for less than £5 which consists of the largest number of things, where the number of those things is written on the packet/box/tin. For those still working on it, do not click on the following link which goes to the best answer I’ve been able to find – 5,000 things for £2.71. http://is.gd/sKpN
[Update – the same idea can now yield a score of 10,000 – T.M. 16/4/11]

Puzzle
This time, the question is simple: why do house front doors almost always open inwards?

Picture
It is reasonably well known that photo manipulation is common on magazine covers, but it’s good to be reminded of how much distortion actually goes on sometimes, in examples such as this:

An interesting collection of images demonstrating the point the other way round can be found in these front covers of an apparently forthcoming edition of the French Elle magazine.
