The sun sometimes turns rectangles into triangles. A nice Sunday morning image.

Yesterday in Triangle Appreciation
I woke up today quite upset that I had missed Triangle Appreciation Day.
Yesterday’s date, 12/10/10, should have been the perfect occasion to celebrate the 12-10-10 triangle:
Rueful that I had missed the opportunity, I thought to myself “Better late than never”, and started to extol the virtues of this fine isosceles triangle. But after working for a bit and experiencing some deja vu, I realized that I had already done this: on 10/12/10!
So, I guess I was early, rather than late. Happy belated Triangle Appreciation Day!

The Arithmeum
The next time you are in Germany, make sure to get yourself down to Bonn to check out the Calculator Museum. Or, you can just visit their website.

The museum is closed on Montags.
I’m not exactly sure what a Theutometer is, but it seems to be available in their giftshop, and I would gladly accept it as a holiday gift.
Appreciation Economics
Efficient Ticket Hypothesis
In a past post, I wondered how a local museum theater could make money showing movies to limited audiences. Well, here is a step in wrong direction, business-wise, anyway: the $0.00 ticket.
All kidding aside, Free Fridays are a great way to get people into the museums, and it’s probably pretty good for business overall. The MoMA was packed with people, and the gift shop–and it’s $40 photobooks and $23 T-shirts–was equally occupied. An interesting question is then “How much does the museum make on each $0.00 ticket?”
An uninteresting question is “why didn’t the security guard just let me in without a ticket, instead of demanding that I go grab two from a big pile on the front desk and then not collect the tickets from me anyway?”
It was enough to make me consider asking for my money back.

Sidewalk Mathematics
Apparently these graffiti compasses were showing up outside subway station exits this summer in NYC.
It’s really hard to say what I like most about this: the fact that it’s functional street art, that it’s mathematical in nature, or that the artist’s handle is I. M. Pi.
