In 1895 Wilhelm Roentgen was performing a routine experiment involving cathode rays. When he noticed that a piece of fluorescent cardboard was lighting up from across the room. The rays somehow illuminating the screen. A thick screen had been placed between his cathode emitter and the radiated cardboard, proving that particles of light were passing through solid objects.
Amazed, Roentgen quickly found that brilliant images could be produced with this incredible radiations. He replaced the tube with a photographic plate to capture images. What creation did it turn out to be? ‘X-rays’
In the 1920s a Scottish researcher, Sir Alexander Fleming was growing bacteria on Agar plates in St. Mary’s Hospital in London. One day he discovered an old Petri dish containing staphylococci that had been left open was contaminated by blue-green Mold from an open window. Being observant he noticed that all the bacteria around it had died. What was born out of this invention? ‘Penicillin’ probably the biggest medical discovery. This led the way to the first naturally occurring antibiotic drug, saving millions of lives.
For the coolest mistake ever. Back in 190s, an 11-year-old boy named Frank Epperson invented Summer treat. One day the kid was playing with his food at their back porch. He mixed some sugary soda powder with water and forgot to bring it back inside. His mixture left out overnight. It was a cold night and the mixture froze. As soon as he woke up the next morning Frank found the frozen soda he blends it and tasted it. This delicious treat is called what now? ‘Popsicle’
In 1945 Percy Spencer an engineer for the Raytheon Corporation was experimenting with a radar related vacuum tube. He realized that the chocolate bar in his pocket starting to melt more quickly than he expected. He becomes intrigued and with the little experimentation with popcorns, Spencer concluded that the microwaves could be concentrated to heat food. Soon after, On October 8, 1945, Raytheon filed a patent for the first microwave.
Pere Suger was the abbot of the Saint-Denis abbey, and on his daily exercise walks in the monastery garden, he noticed how the branches of the trees were entwined above him in the garden of the abbey. He not only thought it was beautiful, but he noticed how the trees supported each other in a storm. He did quick calculations and designs and introduced his concept to the Cistercian monks who were master architect and engineers. When the church of Saint-Denis, the burial church of the French royalty, was rebuilt in 1137, Suger acted as main architect and the old Carolingian basilica was redesigned with ogival arches.
