Saccharin, the first artificial sweetener in the world, was discovered under very unexpected circumstances. 1897, a chemist named Constantine Folberg was studying coal tar derivatives at Johns Hopkins University. One night, when he forgot to wash his hands after work, he found that his hands smelled sweet.
Constantine Folberg soon thought that this sweetness was related to some laboratory equipment, so he went back and tasted every piece of equipment used that day. After tasting all the equipment, he found that the sweet ingredient is a compound called benzoyl sulfonimide, which is 300 times sweeter than ordinary sugar. Later, Constantine Falberg named this compound saccharin and put it into production immediately. During the sugar shortage in World War I, it was widely used as a substitute.
Movilla Cave is an underground cave, located in the suburb of Mangalia, Constanza County, Romania, only a few kilometers away from the Black Sea. 1986, scientist Christian Raskop accidentally discovered a cave that had been closed for 5.5 million years.
It has a unique groundwater ecosystem with low oxygen content, but rich in carbon dioxide, hydrogen sulfide and ammonia. Although this makes caves toxic to humans, some unique creatures, such as leeches, spiders and fake scorpions, have been found, which are completely different from what we know in evolution because they have adapted to the methane in caves and survived in sulfur-oxidizing bacteria. Later, scientists used this discovery to better understand the origin and evolution of life on earth.
The builder 1902 was cutting the reservoir for a new housing development project in Paola town, Malta, and as a result, the underground palace of Har Safranian, which was built during the Safranian period in Malta, was accidentally discovered due to the collapse of the roof. At first, the workers tried to hide the temple, but it was finally discovered.
1903, Themistocles zamis, then director of the Maltese national museum, studied this structure and excavated the objects in the tomb and human remains. In addition, historians have found some pottery samples from 4000 BC to 2500 BC. Through these discoveries, it can be proved that the history of the underground palace in frini, Harsa is even older than the pyramids in ancient Egypt.
Coors Stadium in Denver, Colorado was built from 1993 to 1994, and is the home of the American baseball team Colorado Rockies. In fact, in the process of building the stadium, workers stumbled upon the remains of some prehistoric creatures, and soon rumors about the nature of this discovery began to spread.
Some people claim that they have found a seven-foot-high Triceratops skull, while others think they have found a dinosaur egg. However, in fact, what the staff found were some small ribs, which probably belonged to herbivorous dinosaurs such as Triceratops. Experts believe that this shows that there are more prehistoric remains to be discovered in this area. Later, because of this, the Colorado Rockies also designed the team mascot as purple triceratops.
The oldest known mammoth remains were unearthed in 1965. At that time, a Ukrainian farmer accidentally dug up the mandible of the mammoth while building his cellar, so he contacted experts and found four ancient huts made of 149 mammoth bones here after more excavation.
These houses were built between 23,000 BC and 12000 BC, probably by prehistoric people. However, there are different theories about how to collect these bones. Some historians believe that they were collected during prehistoric hunting, while others believe that they were discovered after natural death. However, the discovered jawbone of mammoth is very helpful for archaeologists to better understand the development of human society in prehistoric times.
Bell Laboratories in New Jersey, USA has the famous Homedel horn antenna 1964. On May 20th, 2004, while studying this kind of antenna, two researchers, robert wilson and Arnold penzias, heard strange buzzing in the sky from all directions, which puzzled them.
Later, they found that this sound is cosmic microwave background radiation, which is the thermal echo that created BIGBANG. In fact, researchers Ralph Alf and Robert Herman first predicted the existence of this radiation as early as 1948. However, it was not until robert wilson and Arnold penzias really discovered this theory and confirmed it. 1978, they successfully won the Nobel Prize in Physics for this discovery.
Modern people should be familiar with leather protectants, which can protect and prolong the service life of our leather furniture. In fact, the invention of this product was completely accidental. It is understood that 1952 two scientists, Samuel Smith and Patsy Sherman, are committed to studying a new type of rubber.
In this project, an assistant of their team accidentally spilled an experimental compound on the floor, some of which landed on Patsy Sherman's tennis shoes. When she tried to remove chemicals from shoes, she accidentally found that this material could be used as a repellent for oil, water and other solvents. Later, in 197 1, two scientists invented the leather protectant together and applied for a patent.
