From Mental Floss:
Hard work and dedication have their time and place, but the values of failure and ineptitude have gone unappreciated for far too long. They say that patience is a virtue, but the following eight inventions prove that laziness, slovenliness, clumsiness and pure stupidity can be virtues, too.
1. Anesthesia (1844)Mistake Leading to Discovery: Recreational drug use
Lesson Learned: Too much of a good thing can sometimes be, well, a good thing
Nitrous oxide was discovered in 1772, but for decades the gas was considered no more than a party toy. People knew that inhaling a little of it would make you laugh (hence the name “laughing gas”), and that inhaling a little more of it would knock you unconscious. But for some reason, it hadn’t occurred to anyone that such a property might be useful in, say, surgical operations.
Finally, in 1844, a dentist in Hartford, Conn., named Horace Wells came upon the idea after witnessing a nitrous mishap at a party. High on the gas, a friend of Wells fell and suffered a deep gash in his leg, but he didn’t feel a thing. In fact, he didn’t know he’d been seriously injured until someone pointed out the blood pooling at his feet.
To test his theory, Wells arranged an experiment with himself as the guinea pig. He knocked himself out by inhaling a large does of nitrous oxide, and then had a dentist extract a rotten tooth from his mouth. When Wells came to, his tooth had been pulled painlessly.
To share his discovery with the scientific world, he arranged to perform a similar demonstration with a willing patient in the amphitheatre of the Massachusetts General Hospital. But things didn’t exactly go as planned. Not yet knowing enough about the time it took for the gas to kick in, Wells pulled out the man’s tooth a little prematurely, and the patient screamed in pain. Wells was disgraced and soon left the profession. Later, after being jailed while high on chloroform, he committed suicide. It wasn’t until 1864 that the American Dental Association formally recognized him for his discovery.
2. Iodine (1811)Mistake Leading to Discovery: Industrial accident
Lesson Learned: Seaweed is worth its weight in salt
In the early 19th century, Bernard Courtois was the toast of Paris. He had a factory that produced saltpeter (potassium nitrate), which was a key ingredient in ammunition, and thus a hot commodity in Napoleon’s France. On top of that, Courtois had figured out how to fatten his profits and get his saltpeter potassium for next to nothing. He simply took it straight from the seaweed that washed up daily on the shores. All he had to do was collect it, burn it, and extract the potassium from the ashes.
One day, while his workers were cleaning the tanks used for extracting potassium, they accidentally used a stronger acid than usual. Before they could say “sacre bleu!,” mysterious clouds billowed from the tank. When the smoke cleared, Courtois noticed dark crystals on all the surfaces that had come into contact with the fumes. When he had them analyzed, they turned out to be a previously unknown element, which he named iodine, after the Greek word for “violet.” Iodine, plentiful in saltwater, is concentrated in seaweed. It was soon discovered that goiters, enlargements of the thyroid gland, were caused by a lack of iodine in the diet. So, in addition to its other uses, iodine is now routinely added to table salt....SIX MORE
