How to Use Physics to Tell If That Steph Curry Video Is Real
A few weeks ago, Sports Illustrated tweeted this video of Golden State Warriors point guard Steph Curry that instantly went viral. It shows him taking a shot at the basket—from the far side of the court. The ball goes in. OK, I can believe that. He’s a famously great shooter. But then he turns around and grabs another ball and takes another shot … and makes it. And then again. And again. And a fifth time.
So is it real or fake? Let’s use statistics and physics to find out.
Basic Probability
Physicists don’t usually jump right into the most complicated version of a problem. Instead, they do a rough estimation, often called a “back of the envelope” calculation. So let’s make some approximations about the probability of making five full-court shots in a row.
We can start with a simple experiment that you can try at home—you just
