  1. Something Blue

    I was at a wedding over the weekend for some friends. During dinner, there was a trivia game and each table (ours was a table of five UPC folk) were able to submit their own questions for round : After the 2012 earthquake in Haiti, what type of plane was JoEllen evacuated on?1 What is…

  2. Lifecycle Costs of Lightbulbs

    Scientific American had an article on the costs of light bulbs1. I wanted to figure out a way to fairly compare the rough lifecycle costs of the bulbs to the consumer. I figured the best way to do that would be to determine the cost per an operating lux-hour. We’re going to figure out the…

Since the funeral isn’t until Monday, we decided to inject some fun and take the train to Montana and then fly back.…

It is possible for one player to hit for a higher batting average than another player during a given year, and to do so again during the next year, but to have a lower batting average when the two years…

  7. Napkin Analysis of the Sand Flea Jumping Robot

    I shared this video1 with Peter, who then asked: I saw that a couple days ago. Awesome! And has some cool practical applications. I [couldn’t] quite tell if the pitch of the robot was adjustable by the user, or of it always jumped in the same direction. Did you get a sense for that? It…
