1、Top 10 Accidental Scientific InventionsHeres the list of top 10 important inventions that were invented through accident or mistakenly lead process.10. Microwave ovensPercy Spencer, an engineer from the Raytheon Corporation was conducting a radar-related research project with a new vacuum tube. Spen

2、cer realized that the candy bar in his pocket began to melt during his experiments. He then put popcorn into the machine, and when it started to pop, he knew he had a revolutionary device on his hands.9. ScotchguardPatsy Sherman, a renowned American chemist, was assigned in a project of developing a

3、 rubber material which wouldnt deteriorate from jet African fuel exposure. Once she dropped a mixture on her shoe and noticed that one spot of her shoe is clean and bright but rest of it is stained and dirty. Later, with more research and experiment she turned this invention into this famous stain r

4、esistant component.8. TeflonIn 1938, Roy Plunkett, a scientist with DuPont, was working on ways to make refrigerators more home friendly by searching for ways to replace the current refrigerant, which was primarily ammonia, sulfur dioxide, and propane. After opening the container on one particular s

5、ample he had 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 w

6、asnt until the 60s that Teflon would be used for its most noted application- nonstick cookware.7. MatchesFor more than 100,000 years, humans have been playing with fire. But no one could create a really easy way to start a fire until a British pharmacist tried to clean his stirring utensil. In 1826,

7、 John Walker was stirring a pot of chemicals when he noticed a dried lump had formed on the end of the mixing stick. Without thinking, he tried to scrape off the dried gob and all of a sudden, it ignited.Walker wasnt interested in patenting the idea, so Samuel Jones copied the matches and sold “Luci

8、fer.“ They were a little more practical than Walkers friction lights. Lucifers were shorter and came in a smaller cardboard box for easy carrying.6. Saccharin (an artificial sweetener)The familiar sweetener in the pink packet was discovered because Constantin Fahlberg, a researcher from Johns Hopkin

9、s University, forgot to do what even a high school chemistry student knows- always wash your hands. He had spilled a chemical on his hands in the lab that caused his bread to taste very sweet. The researcher immediately requested a patent and mass- produced his product.Luckily for dieters everywhere

10、, he managed not to poison himself along the way.5. The PacemakerThe artificial pacemaker is a wonder of modern science. A small, implantable device that regulates a human heart beat through electrical impulses have saved millions of lives was not meant to be invented. John Hopps, an electrical engi

11、neer was conducting research on hypothermia and was trying to use radio frequency heating to restore body temperature. During his experiment he realized if a heart stopped beating due to cooling, it could be started again by artificial stimulation. This realization led to the pacemaker.4. X-RayWilhe

12、lm Roentgen, an eccentric physicist, was interested in investigating the properties of cathode ray tubes. His experiments involved the passing of electric current through gases at extremely low pressure. On November 8, 1895 while he was experimenting, he observed that certain rays were emitted durin

13、g the passing of the current through discharge tube.His experiment that involved working in a totally dark room with a well covered discharge tube resulted in the emission of rays which illuminated a barium platinocyanide covered screen. The screen became fluorescent even though it was placed in the

14、 path of the rays, two meters away from discharge tube. A week after his discovery, Roentgen took an X-ray photograph of his wifes hand which clearly revealed her wedding ring and her bones.3. PlasticsCan you imagine carrying water bottles made of clay or using disposable utensils made of eggs and a

15、nimal blood? The legend of the discovery of plastic says that were it not for two accidents, those might be the materials wed be stuck with today.The started in the lab of Charles Goodyear, who combined rubber and sulfur and accidentally put it on the stove for a period of time. When he came back, h

16、e found a tough and durable material-created through a process eventually called vulcanization.2. AnesthesiaWithout this second last accidental discovery on our list, medical treatments would be a big pain for sure.Crawford Long, William Morton, Charles Jackson and Horace Wells all come to mind when talking about anesthesia. These men realized that in some cases, ether and nitrous oxide (laughing gas) inhibited pain in people under their influ
