In a hurry? Go straight to the graphs.
Two weeks ago was Back To The Future Day. October 21st, 2015 is the day Marty and Doc Brown travel to at the beginning of the second movie. The future is now the past. There were worldwide celebrations and jokes, from the Queensland police deploying a hoverboard unit, Universal Pictures releasing a Jaws 19 trailer and even Health Canada issuing an official recall notice of DeLorean DMC-12 because of a flux capacitor defect that could prevent the car from traveling through time.
I love the trilogy and as many people probably did that week, I rewatched the movies. I also wondered if there was any fun BTTF data science project I could do. While watching the climactic sequence at the end of the third movie, I realized that as the steam locomotive pushes the DeLorean down the tracks, we get many data points as to the speed of the DeLorean. Marty is essentially reciting a dataset, all the way from 1885.
That made me ask the 1.21 Giga Watts question: Do they really make it to 88 miles per hour before they run out of tracks?
