Inventions of the 19th century

Inventions of the 19-20 century are very numerous. The most significant are photography, dynamite, aniline paints for fabrics. In addition, cheaper methods of making paper and alcohol were discovered, new medicines were invented.

Technical inventions of the 19th century were of great importance in the development of society. So, with the help of a telegraph, people were able to transmit messages for a few seconds from one end of the world to the other. The telegraph was invented in 1850. A little later, telegraph lines began to appear. Graham Bell invented the phone. Today, people do not imagine life without this discovery.

Inventions of the 19th century of different countries were brought to the exhibition in 1851 in England. It was attended by about seventeen thousand exhibits. In subsequent years, other countries, following the example of England, also began to organize international exhibitions of recent achievements.

Inventions of the 19th century became a powerful impetus to the development of chemistry, physics, mathematics. A feature of this period was the widespread use of electricity. Scientists of that time were engaged in studying electromagnetic waves and their influence on different materials. The use of electricity began in medicine.

Michael Faraday noticed the phenomenon of electromagnetic induction, James K. Maxwell developed the electromagnetic theory of light. Heinrich Hertz proved that electromagnetic waves exist.

The inventions of the 19th century in the field of medicine and biology were no less significant than in other scientific fields. A major contribution to the development of these industries was made by Robert Koch, who discovered the causative agent of tuberculosis, Louis Pasteur, who became one of the founders of microbiology and immunology, Claude Bernard, who laid the foundations of endocrinology. In the same century, the first X-ray image was obtained. French doctors Brissot and Lond saw a bullet in the head of the patient.

The inventions of the 19th century were also in the field of Astronomy. This science began to develop rapidly in that era. So, there was a section of Astronomy - Astrophysics, engaged in the study of the properties of celestial bodies.

A major contribution to the development of chemistry was made by Dmitry Mendeleyev, having opened the Periodic Law, on the basis of which a table of chemical elements was created. He saw the table in a dream. Some predicted elements were discovered later.

The beginning of the 19th century was marked by the development of machine building and industry. In 1804 a car with a steam engine was demonstrated. In the 19th century, an internal combustion engine was created. This contributed to the development of faster means of transportation: ships, locomotives, cars.

In the 19th century, railroads began to be built. The first was built in 1825 by Stephenson in England. By 1840 the length of all railways was about 7,700 km, then in the late 19th century it was about 1,080,000 km.

It is believed that people began to use computers in the 20th century. However, their first prototypes were invented already in the previous century. Frenchman Jacquard in 1804 opened a way to program a loom. The invention made it possible to control the yarn by means of punch cards, which contained holes in certain places. With the help of these holes, it was supposed to apply the yarn to the fabric.

Invented in the late 18th century lathes, in the 19th century were widely used in industry. The equipment successfully replaced manual labor, processing metal with high precision.

The 19th century is rightfully called the century of the "industrial revolution", railways and electricity. This century has had a huge impact on the worldview and culture of mankind, changing its value system. The invention of electric lamps, radio, telephone, engine and many other discoveries turned the human life of that time.
