Japan’s Shinkansen doesn’t look like your typical train. With its long and pointed nose, it can reach top speeds up to 150–200 miles per hour.

But, in reality earlier models were rounder and louder, often suffering from the phenomenon of "tunnel boom," where deafening compressed air would rush out of a tunnel after a train rushed in. But a moment of inspiration from engineer & birdwatcher Eiji Nakatsu led the system to be redesigned based on aerodynamics of 3 species of birds.

Nakatsu’s case is a fascinating example of biomimicry.
