The manufacture of fermented alcoholic beverages dates back to the Neolithic, a period of human development that began between 6,000 and 4,000 BC, and lasted until 3,000 BC. From the fermentation of the sugar of the honey they obtained mead, with a graduation of 4 to 18% of ethyl alcohol. And from the fermentation of herbs they obtained beer.
Charles Proteus Steinmetz was the one who developed alternating current, which allowed the industrial use of electrical energy.
Johannes Gutenberg invented the printing press in 1440. The first book to be printed was the 42-line Bible (the number of lines on each page), which played an important role in spreading the views of Martin Luther’s Protestant Reformation.

Aluminum foil and the aluminum manufacturing process
The first industrially produced sheet metal in mass use was tin foil, which was replaced by laminated aluminium, paper or aluminum foil after World War II. Charles Martin Hall developed the method for the production of metallic aluminum in electrolytic cells in 1886; Being low in cost, he expanded the use of metallic aluminum in various applications.
Leon Battista Alberti, an Italian artist and architect, invented the first mechanical anemometer in 1450. Anemometer is a device that measures wind speed.

Another related invention is the cardiac pacemaker, an invention of Wilson Greatbatch that began to be implanted in people in the 1960s.
In 1829 it was discovered that the compound called salicin, which was extracted from the bark of willow trees, acted as an anti-inflammatory agent in people, being also an analgesic and antipyretic. But it was already used as a medicine by Hippocrates, who discovered the analgesic properties of willow plants in the 5th century BC. The composition and biological effect of salicin is very similar to that of the active principle of aspirin.

Vehicles powered by a mechanical device have a long history. The first vehicle of this type, powered by a steam engine, was the brainchild of Nicolas Cugnot in 1769. However, the first vehicle with an internal combustion engine using gasoline as fuel was patented in 1860 by Etienne Lenoir. In addition, the construction of the first automobile with an internal combustion engine is attributed to Karl Friedrich Benz in 1886: the Benz Patent Motorwagen.
The electric car, a vehicle powered by an electric motor that stores the energy it uses in a rechargeable battery, was invented in the 1880s; these cars were used at the end of the 19th century until they were superseded by internal combustion engine automobiles. Today the reverse process is taking place, because electric cars do not generate the environmental damage that internal combustion engines do. They are up to three times more efficient, are quieter and have a better response to acceleration. Two-thirds of the roughly 10 million electric cars in use today are pure electric, while the remaining third are hybrids, combining an electric motor and an internal combustion engine.

The first cyclotron was built by Ernest Lawrence and M. Stanley Livingston in 1931. The cyclotron is an atomic particle accelerator.
The electric motor, the device that transforms electrical energy into mechanical energy, was part of Michael Faraday’s developments on electromagnetism.
The light microscope uses optical lenses to magnify the image of small objects. Although there is no agreement on which was the first microscope designed, Zacarias Janssen’s design of the simple microscope in 1590 is recognized as one of the precursors. Then, in 1611, Johannes Kepler would propose the design of the compound microscope.
Max Knoll and Ernst Ruska developed the electron microscope between 1925 and 1932. Using the wave properties of electrons to magnify images of very small objects, its magnification capacity is much greater than that of light microscopes; this is because the wavelength of the electrons is less than that of the photons.

Galvanizing, that is, the deposit of a metal on another metallic surface by electrodeposition using electricity, was invented in 1839. The function of the metallic layer is to protect the body of the piece formed by the other metal, as in the case of the deposition of zinc on pieces of iron. This method is also used to change the appearance of the piece, generating, for example, cheap pieces of jewelry.
The construction of devices to lift objects or people dates back to ancient civilizations and multiple versions have been designed throughout history. As higher-altitude buildings were built, the need arose to design a device that would transport people vertically. On the conception of elevators, in the mid-19th century Elisha Graves Otis invented a brake system to cushion the fall if the cable that supported the elevator was cut; this provided the necessary security for the transport of people and laid the foundations of the elevator as we know it today.
The first explosive created by man was gunpowder, a combination of coal, sulfur, and potassium nitrate. It was invented in China in the 9th century during the Tang dynasty, when alchemists were searching for an elixir for immortality.

Optical fiber is a very thin light-conducting thread that allows information to be transmitted over greater distances and faster than electrical cables. In 1952, the Indian physicist Nrinder Singh Kapany carried out the first experiments that led to its invention, also giving it its current name. He is considered the father of fiber optics.
Freon and refrigerators
Freon is the first compound invented from the CFC (chlorofluorocarbon) group. It was developed in 1928 by a team from the General Motors company made up of Thomas Midgley and Albert Leon Henne in order to replace ammonia and other gases used in refrigeration because they are highly toxic, explosive or flammable. These compounds degrade the ozone layer of the atmosphere, which is why their use in refrigeration systems and in aerosols has been prohibited since 1987.
rockets and missiles
The propulsion of an object to move through the air, initially for war purposes, dates back to the discovery of gunpowder in China and its use to make rockets. The Chinese, Mongols and Ottomans used them for centuries, but in the West they were incorporated into armies much later.
They were used in India against the British in the late 18th century; in turn, the British recorded its importance and promoted its use during the 19th century, with William Congreve being the pioneer in the development of its design and manufacture. But it was in the first decades of the 20th century that the technological advances that allowed their development took place, culminating in 1943 with the production of the V2 rockets designed by Wernher von Braun in Germany during World War II.
Roy Jacuzzi invented and marketed the first fully integrated, self-contained whirlpool bath in 1968, by incorporating water jets into the sides of the tub. Jacuzzi is the registered trademark name for the invention.
Penicillin, the first widely used antibiotic, was discovered by Alexander Fleming in 1928; however, its use prior to Fleming’s discovery by the Costa Rican scientist Clodomiro Picado Twight is also recognized. Ernst Boris Chain and Howard Walter Florey developed a method that allowed its mass production.
Artificial satellites, human-made objects that orbit the Earth, began to be developed in the 1950s, with the Soviet Union’s Sputnik 1 being the first artificial satellite; it was released on October 4, 1957.
Satellites are made for very different purposes: some are both Earth and space observation satellites, others are used for communications or geolocation; there are also weather and navigation satellites. Space stations are also satellites.
Preston Tucker first included seat belts in 1948 on the only model car he ever produced, the Tucker Torpedo.
High-rise buildings began to be built in the late 19th century in the United States, first in Chicago and then in New York. The Home Insurance Building built in 1885 in Chicago is considered the first building of its kind.
Sonar, the device that uses the transmission and reflection of acoustic waves in water to locate and identify submerged objects, was developed after the sinking of the Titanic in 1912. The first patent for such equipment was filed by Lewis Richardson one month after this accident and in 1913 Alexander Behm applied for another patent for similar equipment.
Robert Fulton designed and built the first steamship, which made its maiden voyage sailing along the Hudson River in the United States in 1807. Fulton also designed one of the first sailing submarines, the Nautilus.
It is steel is an alloy of iron and carbon that can have other components in small proportions. The oldest steel elements were found in Africa and their manufacturing date was determined in the year 1400 BC. Steel production in China is also recorded during the Han dynasty, around the 1st century BC.
The first television device was developed by Scottish inventor John Logie Baird, who made the first demonstration on January 25, 1926. He also invented the first color television system. The first public television broadcasts were made in 1927 in England, in 1930 in the United States and in 1935 in France.
The thermos, the device that thermally insulates the material it contains, was invented by James Dewar towards the end of the 19th century. It is also called a Dewar glass.
The use of tidal energy
The first time that tidal energy was used was to propel windmill blades in coastal areas by filling tanks at high tide, driving the mill by draining accumulated water. There are records of this use of tidal power in the Roman Empire and in the Middle Ages. Currently there are power plants that use tidal energy, a clean source that is more predictable than the wind.
The touch screen was developed by Eric Johnson at the Royal Radar Establishment in Malvern, England, in 1965. Its application in air traffic control systems was published in 1968.
