THE SMALLPOX VACCINE
In 1775, Jenner began a detailed study of the relationship between cowpox and human pox. After experimenting with animals, he discovered that if he took an extract from a cowpox sore and injected it into a human being, that person was protected against smallpox. In 1797 he presented the study to the Royal Society describing his experiment. The scientists' response was that his ideas were too revolutionary and that he needed to present more evidence. -
ANESTHESIA
Anesthesia is one of the most important leaps in the history of medicine. Surgical interventions save thousands of lives a day, but before patients were fully anesthetized, many died of trauma or even preferred death to going through the gulp of an operation. Everything changed on October 16, 1846. When William Morton successfully used ethyl ether in a tooth extraction, and two weeks later he gave a public demonstration of his achievement. -
ELEVATOR
In 1852 the American Elisha Otis created a steam elevator that conquered the market, since thanks to its ingenious automatic security system fear was lost and its use spread in buildings that could afford it. -
TELEPHONE
Antonio Meucci was the inventor of the telephone.In 1854, Meucci built a telephone to connect his office with his bedroom. However, he lacked enough money to patent it, so he presented it to a company that neither paid attention to him nor returned the materials. This invention and its subsequent development gave a strong boost to communications through the use of technology produced with the use of electricity as a conductor. -
CLINICAL THERMOMETER
In 1866, the English physician Thomas Clifford Allbutt, created the handheld clinical thermometer. The need for proper equipment to measure the progress of fever in the patient's own bed led Albutt to invent the six-inch clinical thermometer, capable of measuring temperature in only five minutes. -
COCA-COLA
The history of Coca-Cola began in 1886 when John Pemberton, an Atlanta pharmacist, was searching for a drug to cure his addiction to morphine acquired during the American Civil War. He developed a formula in the form of a syrup and mixed it with carbonated water. Frank Robinson, when he tasted the drink, thought about marketing it, and gave it the name Coca-Cola for its two main ingredients: coca leaves and cola nuts. -
AIRPLANE
Clément Ader observed the flight of numerous species of birds and bats, which he captured and kept in facilities built in his own home. Since its purpose was to achieve a machine with a lifting force that counteracts that of gravity and that of the weight of the materials used. This resulted in the construction of a flying apparatus that Ader called the Greek god of the winds (Eole) and when he patented it in 1890, he called it "airplane" -
CINEMATOGRAPH
On March 22, 1895, at the premises of the Parisian Society for the Promotion of National Industry, the brothers Louis and Auguste Lumière made the first private screening of their cinematograph. It was the cinematograph invented by the Lumière brothers that revolutionized the image projection scene, giving rise to the modern film industry. -
ASPIRIN
The young German chemist, Felix Hoffmann discovered one of the most headache-relieving substances in the world, acetylsalicylic acid. In the Bayer Company chemistry laboratory while Hoffmann was working with another substance, he managed to obtain acetylsalicylic acid in a chemically pure and stable form. The substance was shown to have analgesic, antipyretic and anti-inflammatory effects. In 1899, the Bayer Company released it under the name Aspirin. -
THE THEORY OF RELATIVITY
The development of the theory of relativity formulated by Albert Einstein at the beginning of the 20th century laid the foundations for modern nuclear physics and allowed the subsequent development of numerous advances in quantum physics.
