Top 10 Accidental Scientific Discoveries That Changed the World


10 Vulcanised Rubber

Vulcanized rubber is a vital form of rubber that is used to create a wide range of products, including tyres, shoe bottoms, and conveyor belts. Intriguingly, it was found by chance in 1839 by Charles Goodyear, a physicist. When he placed the rubber, sulphur, and lead combination onto a hot burner, the rubber stiffened but remained workable. This is how the world obtained a rubber that can withstand both heat and cold.

9 Safety Glass

You may be aware that your car’s windshield is constructed of laminated glass, which is less likely to shatter and cause injury to your eyes. Apparently, the safety glass that protects you from accidents was designed as a result of an accident. When a French scientist named “Édouard Bénédictus” dropped a glass flask containing polymeric cellulose and nitrate in 1903, it strangely did not break as it should. After a few minor changes, the safety glass became as flawless as we know it today.

8 Sildenafil

Sildenafil, also known as “Viagra,” is a little blue tablet that is frequently used to treat erectile dysfunction. Sildenafil was a wonderful finding in and of itself, but it happened by chance. UK-92480 was developed by a group of pharmaceutical chemists at a research centre in England in the early 1990s to treat hypertension and Angina pectoris (a heart disease). However, test subjects reported some startling effects below the belt, despite the fact that it eventually turned out to be an unmitigated failure in that regard. What’s more intriguing is that it has certain negative side effects, one of which being “heart attack.”

7 Matches

Strikeable matches were the sole means to have rapid and simple access to fire until lighters were invented. John Walker was on the lookout for a simple technique to acquire fire. While various chemicals might be ignited by a quick explosion at the time, it was uncertain if the flame could be conveyed to a slow-burning solid such as wood. This astounding scientific discovery occurred when Walker was creating a lighting combination, when a match that had been dipped in it caught fire due to inadvertent friction on the fireplace. Even he was taken aback by the news.

6 Teflon

Teflon is said to come into contact with every individual at least once a day. Teflon, commonly known as “Polytetrafluoroethylene,” is the most significant polymer on the planet. When Roy Plunkett was attempting to develop a new chlorofluorocarbon refrigerant in 1938, he made an unintentional discovery. In a pressured container, he poured tetrafloroethylene. He discovered that the inside of the container was coated in a strange waxy white substance that was strangely slippery. It was later discovered that it was polymerised perfloroethelene.

5 Corn flakes

Kellogg and his younger brother, Will Keith Kellogg, allowed some cooked wheat to sit while they attended to some important business at the sanitarium on August 8, 1894, and the concept for corn flakes was born. When they returned, they discovered that the wheat had gone bad. However, because they were on a tight budget, they chose to continue processing it by exerting force via rollers in the hopes of obtaining lengthy sheets of dough. They were surprised to find flakes instead of a sheet of dough, which they toasted and served to their patients. Eventually, a multibillion-dollar industry began to feed hundreds of millions of people every morning.

4 X-ray

The discovery of X-Rays is ascribed to Wilhelm Röntgen, a German scientist. When he spotted a strange glow in his dark chamber, he was really working with cathode ray tubes. He immediately understood that a new form of ray was to blame, but he had no idea what kind of ray it was, so he just dubbed it x-ray. The capacity of x-rays to travel through a variety of objects and reach locations where our visual spectrum does not enable us to reach is what makes their discovery so revolutionary.

3 Microwave Radiation

Although James Clark Maxwell anticipated the presence of radio waves in his equation in 1884, it wasn’t until 1943 that a Hungarian engineer named Zoltán Bay identified the radiation of this wavelength. He was hunting for energy sources for radar equipment when he noticed a chocolate bar melting in his penthouse. After a few years, they’re still in use for a variety of things, including the ovens your mothers use to create beautiful cakes.

2 Plastic

Leo Baekland, a Belgian-American chemist, began trying in 1907 to discover a substitute for shellac, an exceedingly costly material created naturally from the excrement of a lac insect. However, he only partially succeeded, instead producing the marvellous substance known as Plastic. He mixed formaldehyde, phenol, and a few other ingredients to create a nonconductive, heat-resistant polymer. Plastic is utilised in a wide range of items, from paper clips to spacecrafts, and even in the gadget you’re using to view this page, because to its low cost, simple production process, adaptability, and water resistance.

1 Penicillin

You may be aware that penicillin is one of the first and most significant medicines to effectively combat bacterial illnesses. On the morning of Friday September 28, 1928, a momentous discovery will impact the lives of all humans. Alexander Fleming, a Scottish chemist, left a Petri plate with staphylococcus in his laboratory in the basement of St Mary’s Hospital in England by mistake. He found that staphylococcus was contaminated with blue-green mould from an open window when he returned from a two-week vacation, and that germs were unable to grow around it.
