(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:

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:
This guy makes armour for cats and mice. Or perhaps more accurately, scale sculptures that resemble such things:
Best of Things 2008
Worst translated menu in the world
XKCD on dreams and possibilities.
Acoustic Resonance – rice is used to illustrate standing acoustic waves on what I presume is a metal plate:
Analemma (click for big):
If you don’t know what an Analemma is, try to work it out from the photo.
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.
