To assemble the dataset, I simply watched the train sequence and took down each time Marty said the speed, or that we saw it on the speedometer, along with the time in the movie. That would have made things easier considering the DeLorean was equipped with a working Mr. If you think of it, it’s a shame Doc didn’t equip the DeLorean with Tesla electric motors when he visited 2015. According to my calculations we’ll hit 88 miles per hour just before we hit the edge of the ravine, at which point we’ll instantaneously arrive in 1985 and coast safely across the completed bridge. We’ll stop it here, uncouple the cars from the tender, throw the switchtrack, and hijack – borrow the locomotive and use it to push the time machine. The train leaves the station at 8:00 Monday morning. The switch track is where the spur runs off the main line 3 miles into Clayton… Shonash Ravine. Tomorrow night, Sunday, we’ll load the DeLorean on to the tracks here on the spur right by the old abandoned silver mine. The plan they come up with is to commandeer a steam locomotive and use it to push the DeLorean to the required speed.ĭoc spells out the plan to make it back to the future: That means they can’t drive it to 88 miles per hour, the speed required to activate the flux capacitor, and travel back to 1985. 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?įor those not familiar with the movies, Marty and Doc are trapped in the old West without any gas to power the gasoline engine of the DeLorean, their time-machine. Marty is essentially reciting a dataset, all the way from 1885. 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. I also wondered if there was any fun BTTF data science project I could do.
I love the trilogy and as many people probably did that week, I rewatched the movies.
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. October 21st, 2015 is the day Marty and Doc Brown travel to at the beginning of the second movie. Two weeks ago was Back To The Future Day.
The dataset and notebook detailing how this was done are available in the companion repository.
