The accidental scientific discovery possible

Penicillin antibiotics, anti-stick agents, pacemakers, . are important scientific discoveries of humans born in extremely 'natural' circumstances.

1. Penicillin

Penicillin is considered one of the inventions thanks to the most famous 'occupational accident' of the twentieth century. In 1928, scientist Alexander Fleming forgot to clean his research tool before he took a few days off. When he returned, Fleming saw a lot of bacteria and mold on his tools. However, he also found that there are some areas where bacteria and mold do not develop. In 1940, scientists at Oxford University successfully separated penicillin and developed it into the first human antibiotic. So far, Penicillin is still the most widely used and widely used antibiotic.

2. Pacemaker

Wilson Greatbatch, an American engineer who accidentally created a pacemaker in one mistake. When Wilson was trying to create an oscillator to record the sound of the heartbeat, he hung up the resistor. However, Wilson still recorded the heartbeat. Since then, he has successfully built a pacemaker with the help of William Chardack. The first test conducted and succeeded in 1959 led Wilson to become the first in the world to build a pacemaker.

3. Dye

At the age of 18, in a research effort to cure malaria, chemist William Perkin created something that had nothing to do with science and something extremely significant to science. It was in 1856, Perkin tried to create artificial parasites. The result he obtained was a black solution. When observing them, Perkin noticed a beautiful color in the black liquid. And he discovered that he had created the first synthetic dye.

This dye is much better than natural dye. Colors are brighter, more vivid, do not fade or fade when washed. His discovery also became a precursor to a new science.

However, the story has not ended here. Paul Ehrlich, a German bacteriologist, who was inspired by Perkin from dyeing, discovered immunological and chemotherapy methods in medicine.

4. Radiation

In 1896, physicist Henri Becquerel was fascinated by two things: natural fluorescence and X-rays. He conducted a series of experiments to examine the ability of natural minerals to produce fluorescent lamps. After they are separated from sunlight.

However, Henri Becquerel conducted experiments in the winter and for a week, the sky was overcast. So he put the devices together in a drawer and waited for the sunny day. On a sunny day of work again, Henri discovered that the uranium stone he had placed in the drawer had imprinted it on a photograph without exposure to sunlight. Henri worked with Marie, Pierre Curie and discovered that it was radioactive.

5. Plastic

In 1907, lotus - shake was used to make insulation in the electronics industry. Therefore, this industry must always spend big expenses on imports of lotus from Southeast Asia. Because of this, chemist Leo Hendrik Baekeland thought that he could earn a big profit if he produced a new material to replace the lotus - shake.

However, his research experiments created a material that did not change shape under high temperature. Baekeland thinks it can be used in making records. But, more than what he wanted, the new material quickly appeared in a wide range of products with thousands of users. And so far, plastic can be found everywhere.

6. Rubber vulcanization

Charles Goodyear scientist spent a decade in his life trying to make rubber easier to use and resistant to heat and cold. However, his research failed. Until one day, he accidentally poured a mixture of sulfur, rubber into a hot stove. Under high temperature, the rubber melted but not destroyed. When the process ended, Charles Goodyear found the mixture hardened but still useful. From Charles Goodyear's discovery, many vulcanized rubber products were born and used everywhere.

7. Teflon - Non-stick agent

Researcher Roy Plunkett in the process of research to find a new form of CFC (chlorofluorocarbon). He said that if he could get TFE mixed with hydrochloric acid, he could produce the refrigerant he wanted. So Roy cooled the TFE, compressed it in a storage box so he could use it when needed.

After a while, he opened the box to store TFE to mix with hydrochloric acid, there is nothing left in the box. Looking closely at the bottom of the box he discovered a thin layer of white powder. He conducted the experiment and found that it has good heat resistance and effective adhesion. With this discovery, Plunkett received his patent in 1941. The new substance was named Teflon in 1944.

8. Coca-cola

There are many foods that have been invented in random cases, but perhaps no food has a special and secret history like coca - cola.

Pharmacist John Pemberton in Atlanta, USA in an effort to cure headaches that blends different ingredients and creates a drink. And this drink, after eight years of being sold in pharmacies, has become a popular drink all over the world. So far, the recipe for this drink is still a secret.

9. Chemical sugar

In 1879, chemist Constantin Fahlberg spent much time researching coal tar derivatives in the work of Professor Ira Remsen. When he returned home to have dinner with his wife and forgot to wash his hands, he noticed a strange sweetness from the dish that day. He asked his wife and she said nothing else. Then he discovered that sweetness came from his hand.

The next day, he went to the lab and continued to study this and discovered the chemical pathway - an invention that is considered a breakthrough of humankind.
