As Plato said, “science is nothing but perception,” and these 10 accidental acts of discovery embody the sentiment. Of course, it helps to be a leading scientist in the field—devoting your life to the pursuit of one cure, invention, or innovation—but a little luck goes a long way, too. Forever enshrined in scientific legend, the discovery of penicillin—a group of antibiotics used to combat a variety of bacterial infections—is really just a case of dirty dishes. Scottish biologist Alexander Fleming took an August vacation from his day-to-day work in the lab investigating staphylococci, known commonly as staph. Sometimes all you really need to make the next leap in science is a snack. Percy Spencer was an American engineer who, while working for Raytheon, walked in front of a magnetron, a vacuum tube used to generate microwaves, and noticed that the chocolate bar in his pocket melted. Spencer successfully invented the first microwave oven. Snacking, then, is good for science. On one particular hiking trip in 1941, Swiss engineer Georges de Mestral found burrs clinging to his pants and also to his dog’s fur. On closer inspection, he found that the burr’s hooks would cling to anything loop-shaped.

If he could only artificially re-create the loops, he might be on to something. A combination of the words “velvet” and “crochet,” the material had trouble gaining traction in the fashion industry. But one of its most notable clients in the 1960s was NASA. The agency used the material in flight suits and to help secure items in zero gravity. After that, it became a space-age fashion all its own, allowing kids everywhere to put off learning how to tie shoelaces. The secret to discovering the prevailing theory to how the universe was made began with noise, like common radio static. In 1964, while working with the Holmdel antenna in New Jersey, the two astronomers discovered a background noise that left them perplexed. In fact, only 37 miles from the Holmdel antenna at Princeton University, Dicke and his team had been searching for this background radiation.

When he heard the news of Wilson and Penzias’ discovery, he famously told his research partners, “well boys, we’ve been scooped. Penzias and Wilson would go on to receive the Nobel Prize. After opening the container on one particular sample he’d been developing, Plunkett found his experimental gas was gone. All that was left was a strange, slippery resin that was resistant to extreme heat and chemicals. In the 1940s the material was used by the Manhattan project. A decade later it found its way into the automotive industry. It wasn’t until the ’60s that Teflon would be used for its most noted application: nonstick cookware. In the 1830s, natural rubber was a popular substance for waterproof shoes and boots, but its inability to withstand freezing temperatures and extreme heat soon left consumers and manufacturers frustrated.

That led some to say rubber had no future, but Charles Goodyear disagreed. After years of trial and error trying to make rubber more durable, the scientist stumbled upon his greatest discovery by complete accident. His surname and legacy live on, however, in the Goodyear Tire and Rubber Company, which was named after him nearly 40 years after his death. The inventor of the Coca-Cola wasn’t a shrewd businessman, a seller of sweets, or a dreamer looking to strike it rich in the beverage business.
