Minneapolis No Parking

Dave Oosterhuis discovers the wonder of parking signs and the mathematical relationships found in them.

Mr. Oosterhuis explored a number of solutions for this sign and finally settled on this one.

\sqrt{9} - \sqrt{4} = 7 - 6

This sign is found on Lyndale Avenue, between 38th and 39th street south in Minneapolis, Minnesota. The GPS coordinates are approximately N44.93323 W93.28800. See sign on map!

Ed.: We’ve seen a rash of these signs and may have to stop posting these simple parking or other hour slot signs. They are usually a gimme since the time slices they cover are intended to be equal.

    Not sure about banning ‘no parking’ signs…

    But I do love the scoring rules that make us twist a simple math like this sign has

    (9-7) = (4-6), and allows us to hunt for the more obscure relationships between numbers.

    I tend to agree with you Randy, it makes for more interesting math. However, I do hope that it doesn’t trend the game to the bizare! It seems people shoot more for the technical score and to a certain extent ignore the elegance score. This makes sense, you cannot control the elegance score and you can impact the technical.

    We’ll see how it evolves over time.
