🥛 1. The internet is connected by 'milk bottles' and 'submarines'? Do you think we use satellites for international internet access? Actually, 99% of global cross-border internet data is transmitted through submarine fiber optic cables laid on the seabed, totaling over 1.2 million kilometers. Even cooler, to prevent the cables from being bitten by sharks in the deep sea, scientists even use high-density polyethylene (HDPE) materials, similar to those used in making milk bottles, to wrap them. 🕊️ 2. Birds almost became the original 'missile guidance system' Before modern chips and AI, behavioral psychologist B.F. Skinner developed a 'pigeon-guided missile' project. He placed 3 trained pigeons at the front of the missile. When the pigeons saw the target screen and pecked at it, they could adjust the missile's flight direction. Although the test was successful, the military found the idea too absurd and canceled it. 🐜 3. The first computer 'Bug' was a real bug In 1947, legendary computer scientist Grace Hopper was debugging the Mark II computer when she found the system kept malfunctioning. They eventually opened up the machine and discovered a moth stuck in a relay. She taped the moth to her logbook and wrote, "This was the first actual case of a bug being found," and from then on, computer errors were called bugs.
