Pennsylvania was accidentally invented by Alexander Fleming in September 1928. Fleming was a bacteriologist by profession, a person who studies germs. He often performed his experiments at St Mary’s Hospital in London. One day he placed an experimental plate containing staphylococci bacteria by the window. When he returned a few hours later, he found that some of the molds on the window had been blown away and had damaged the bacteria. Someone else would throw the plate out and start the experiment again.
But he looked at the plate carefully, and when he placed it under his microscope, he saw that it looked like staphylococci. Surprisingly, the whole area around the mildew was clean. It so happened that the fungus was devouring this poisonous Steffa Lou Kaki, so Coincidentally Fleming invented the Pen C Lane. In 1945, Fleming, Flory, and China were awarded the Nobel Prize for their invention of the Pencil. Doctors in the United States prescribe more than 100 million prescriptions each year.
Bath soap is widely used in the United States and Canada. The formula was developed 125 years ago by two brothers, James, and David Gamble Campbell.
Initially, they named it White Soup, but at that time, it did not float in water. But it was invented by accident. One day a worker in the factory was working on a big machine. But at lunch, he forgot to turn off the machine. The machine was running continuously. When he returned after lunch, he noticed that the air had been added to the soap mixture. Instead of throwing the mixture, he put it inside the mold. When the soap hardened, it was cut and packaged into three or four soaps and sent to stores for sale. Soon Procter & Gamble began receiving orders because the soap was floating. The slightest mistake by the worker-led to the sale of the soap. In 1879 it was renamed Ivory Soup.
10 million bricks were used in the construction of the Empire State Building in New York. The Great Wall of China has 4 billion bricks. A man started using bricks ten thousand years ago. The first brick was made by an Egyptian by chance from a pile of mud and debris deposited on the banks of the Nile. When the mud in the sun hardened, someone made a slab out of it. Another Egyptian came up with the idea, why not cut this block and use it to build a house. The way bricks were made thousands of years ago.
The same is done today. The city of Arkansas in the United States is famous for its brick kilns. There is a fair here every year, with a brick fair called Brickfest. There is a brick museum in Johnson City, Tennessee. The world’s oldest brick has been found in the Israeli city of Jericho, which is 9,000 years old. A 5,000-year-old fire broke out in the Indian city of Kali Banga. It is said that the brick of King Solomon’s fortress in Israel weighed 64 pounds.
Post at note:
You must have used the yellow Post-it Note in the office. There is a slight glue on the back of the paper. But paper is easily separated from other papers. This type of paper was invented in 1970 in the research laboratory of the famous American company 3M3M. It so happened that one of the company’s scientists, Spencer Silver, was working on a strong adhesive in the Silver Laboratory. It made a glue, but it was even weaker than the first one, which was already being made in 3M. The glue that is applied will stick to other things. But it was also easily separated, meaning that the glue was Super Week instead of Super Strong.
