Things Christmas Special 2008

(Originally sent… okay, you can probably guess)

It’s Christmas and Things has been running for over a year. I’m taking that as an excuse to break with the usual format, and also to highlight what I (and some others) consider to be the best of the year’s Things.

Urgent matters first
I bought 10 tubs of Celebrations chocolates, discovered the average distribution of the different types, then created tubs of each kind and put them on eBay for charity to determine their value. I wrote up the initial results in my new blog:

The auctions end AT LUNCHTIME TODAY!

Check out how they are doing, or bid if you are so inclined, here:

[It’s long over now, read the final results here – T.M. 22/1/11]

Videos
Here are some videos that I like.

1) Tim ‘Speed’ Levitch is an extraordinary fellow that speaks in paragraphs that would take most other people hours to come up with. In the following video he holds forth on the New York grid plan and builds to a brilliant conclusion.

To sell you his style just a bit more, here’s his spontaneous introduction to a comment on a homeless person he passes while walking down the street: “[that person], under the white comforter, cuddled up with 34th street and Broadway, existing on the concrete of this city, hungry and dishevelled, struggling to crawl their way onto this island, with all of their machinated rages and hellishness and self-orchestrated purgatories…”

2) Somebody put a few frames of an anime featuring a woman spinning a leek around to a brilliantly loopy sample from an obscure band. A massive internet meme was born. Here’s where it all started (reposted).

Wikipedia article on the phenomenon.

3) This is my favourite tune and music video right now, and the intro guy is awesome too:

Pictures
This guy makes armour for cats and mice. Or perhaps more accurately, scale sculptures that resemble such things:

Puzzle
The rainbow paradox, remains one of my favourite and (as far as I am concerned) unresolved puzzles:

Soundwaves can vary in frequency across a vast range, part of which we can hear. The lowest part we perceive as a deep bass, the highest as a high squeak.

Similarly, the electromagnetic spectrum consists of a vast range of frequencies, a small range of which we are able to see. The lowest frequency we can see is what we call red, and the highest frequency is what we call violet.

However, while we perceive the ends of the audible sound spectrum to be very different, the ends of the visible light spectrum, red and violet, seem very close to one another, and we even have a colour we call purple that is a mix of the two yet does not actually appear anywhere in the spectrum between them. In fact, we can draw a circle of the colours we perceive and it is not at all clear where the ‘ends’ are.

Why is this?

That’s it for Things until 2009.

Happy Thingking!

Things 36: Amara’s Law, Wondermark, hahahahah

(Originally sent December 2008)

The ‘Things’ email has existed in one form or another for over a year now. The fact that this is number 36 and not 52 shows that I clearly take too many Fridays off. (Actually it was mainly due to a big hiatus). Anyway, I have this Friday off, but have decided that that is not a good enough excuse.

Owing to the popularity of the chicken video last week and the sort-of anniversary of Things and the approaching of Christmas and the addition of more people to the list over the year, I thought it might be an idea to have a ‘Best of Things’ roundup next week.

So please reply and nominate your favourite items that have ever appeared in Things, and I will use these to compile a top 5, or something. I guess the people that just joined in the most recent wave don’t really have enough to go on, sorry! [Note, not a live question, this was sent in December 2008! – T.M. 22/1/11]

Wondermark is a webcomic that is also a really great example of the value of copyright expiry. David Malki takes images from the 1800s (sourced from the public domain or his own collection of rare books), does a bit of photoshop and then adds speech bubbles.

He’s actually not bad at drawing either, but his writing is really very good, and this enables him to focus on that.

My personal favourite strip is a great example of how he makes humour out of philosophy:
http://wondermark.com/413/

My favourite sequence consists of four strips about getting rich, or not, which begins here:
http://wondermark.com/383/

A good example of his skill as a writer can be found in the following strip, in which there is a well-argued, thoughtful and erudite argument against the advertising for Shrek the Third, in about 60 words:

Puzzle
Last week we wondered why a chicken holds it’s head so still. A bit of Googling didn’t prove it immediately, but I am pretty confident that the reason is this: their vision, or processing of vision, is either movement-based or strongly prioritises movement. A bit like the dinosaurs in Jurassic Park.

This week a bit of estimation for you. In the UK, are there more households with dogs, or more with cats?

A Video (or two)
This video was brought to my attention by Richard. Alan Watts was a dude who knew what he was talking about, and said some wise things. The South Park guys did some animations that went with those things. Here is my favourite:

For you cat/Roomba fans, here’s another video of a cat riding a Roomba – this time the Roomba is behaving normally rather than being remote controlled. It gets a bit repetitive but do skip to the end if you get bored, as Something Happens:

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.

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.

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.
