In Computer Programming we’ve been working with Python for the past two days. The students are walking through a tutorial to get used to the language, and one of them made a program that was counting down. He entered a starting number of 100,000,000,000,000,000,000,000. It was taking about 30 seconds to countdown by ten thousand. He was wondering how long would it take to count down to 0? About 10 trillion years.
