My wife replied "Grandpa can probably figure out if that's true". Challenge accepted. World watermelon production is 105 million metric tons a year. That works out … Continue reading Who’s Having Watermelon?

I recently went in for a blood draw. After they called me back to the lab, the phlebotomist confirmed my identity by asking my last name and date of birth. That got me thinking.

New York City has detailed data on traffic crashes over the past 14 years. My previous post looked at the when these incidents occur; mostly the time-of-day. Today I'll look at why they happen (and okay, also when). Each collision report lists up to five vehicles; for each vehicle, a "contributing factor" can be specified. … Continue reading Why Crashes Happen

New York publishes detailed information on every traffic accident - er, motor vehicle collision, that has occurred in the city.
