A few of my favorite listings on 101questions this week:
- A Fistful of Quarters (and Dimes), Nathan Kraft. Provokes the comparison of the value of a coin against its weight, which seems at first like a useless ratio. But remember the nickel thieves? If someone let you carry as much change away as you could lift, which kind of coin would be the smartest pick?
- Pennies, Friedrich Knauss. Provokes the comparison of the value of a coin against its surface area which, again, seems like a totally useless ratio until you see a photo like this. If you were going to carpet your floor with a particular kind of currency, which would be the smartest pick?
- Handshakes, Craig. Love the clip. I find the question, "How long would it take to infect the whole office?" irresistible.
- Coins, Steve Phelps. I've noticed these kinds of first acts are difficult to pull off. (Check, please, also uploaded last week, is struggling, for instance.) They're often too cluttered or they place students too high up the ladder of abstraction too quickly. Steve Phelps strikes a nice balance here. Moreover the task is open to several correct answers, which is unusual for material you'll find on 101questions.
- 1982 Osborne Executive vs. 2007 iPhone, Carl Malartre. I tried a similar approach with Evolution. I like Carl's more.
