The squid nerves behind a famous circuit

HERE’S THE INTERESTING PART

Long before tech bros hyped up biohacking, Otto Schmitt was literally raiding the ocean for engineering ideas. By studying the electrophysiology of giant squid nerves, he reverse-engineered how they propagate signals to create the Schmitt trigger. He basically ripped off a mollusk's biology to invent a noise-filtering electronic circuit we still use today.
