ACCIDENTAL DISCOVERIES
that changed out lives
Not everything we invented were actually intented to be created. Some of them where accidental discoveries. So what are these accidental discovers?
Here are 5 accidental discoveries that made our lives better.
X-Ray.
When Röntgen held a piece of lead in front of the electron-discharge tube, it blocked the rays, but he was shocked to see his own flesh glowing around his bones on the fluorescent screen behind his hand. He then placed photographic film between his hand and the screen and captured the world's first X-ray image.Super Glue.
It actually took 2 accidents to create super glue. In 1942, Dr Harry Coover attempted to create crystal clear plastic-based gun sights with acrylates during world war two. But it was abandoned as the substance, was too sticky.
9 years Later, working with a heat-resistant coating for jet cockpits, at one point he spread the earlier discovered ethyl cyanoacrylate between a pair of prisms. To his surprise the substance required no heat or pressure to work its adhesive. This time he did not abandoned his work. Hence was Super Glue rediscovered.
Insulin.
In late-1880s, two German researcher Oskar Minkowski and Joseph von were studying digestion in a dog and removed its pancreas, they noticed that flies gathered around the dog's urine. Which on testing, they noted that it had a high sugar content. Further research revealed that a pancreas accomplishes that task by releasing insulin.
Match Stick.
In 1826, John Walker noticed a dried lump on the end of a stick while he was stirring a mix of chemicals. When he tried to scrape it off, he got the sparks and flame.
Velcro.
In 1941, Swiss engineer George de Mestral went for a hike in the Alps with his dog. Upon returning home, he took a look at the small burdock burrs that stuck to his clothes, and noticed that the little seeds were covered in small hooks, which is how they became attached to fabric and fur.
After noting how firmly those little burrs attached to fabric, he decided to create the material that we know now by the brand name Velcro. 20 years later NASA popularized it.
