Inventions 19-20 century are numerous.The most important may be called the photo, dynamite, aniline dyes for fabrics.In addition, we opened cheaper methods of making paper, alcohol, inventing new medicines.
Technological inventions of the 19th century were of great importance in the development of society.So, with the help of the telegraph people could send messages within seconds from one end of the world to another.Invented the telegraph in 1850.A little later, began to appear telegraph lines.Graham Bell invented the telephone.Today people can not imagine life without this discovery.
inventions of the 19th century all over the world 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, have also started to organize international exhibitions of the latest advances.
inventions of the 19th century became a powerful impetus to the development of chemistry, physics, mathematics.A special feature of this period was the widespread use of electricity.Scientists have been studying the time of electromagnetic waves and their effects on different materials.We began to use electricity and medicine.
Michael Faraday had observed the phenomenon of electromagnetic induction, James C. Maxwell developed the electromagnetic theory of light.Heinrich Hertz proved that electromagnetic waves exist.
inventions of the 19th century in the field of medicine and biology were no less significant than in other scientific fields.Great contribution to the development of these industries have Robert Koch 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 this century it was obtained first X-ray image.French doctor and Brissot Londe spotted a bullet in the head of the patient.
inventions of the 19th century were in the field of astronomy.This science began to develop rapidly in that period.So, there was a section of Astronomy - Astrophysics, has been studying the properties of celestial bodies.
great contribution to the development of chemistry has made Mendeleyev, discovered the periodic law, on the basis of which was created a table of chemical elements.The table he saw in a dream.Some predicted elements were discovered later.
early 19th century was marked by the development of engineering and industry.In 1804 the car was shown to the steam engine.In the 19th century it was established the internal combustion engine.This has contributed to the development of faster means of transportation: ships, locomotives and cars.
In the 19th century began to build railroads.The first was built in 1825 by Stephenson in England.By 1840, the length of railways was about 7700 km, at the end of the 19th century it was about 1,080,000 km.
believed that people began to use computers in the 20th century.However, the first of their pre-images were invented in the previous century.Frenchman Jacquard in 1804 opened the way to program the loom.The invention allows to manage thread using punch cards that contained holes in certain places.Through these holes intended application of the thread on the fabric.
invented in the late 18th century, lathes, in the 19th century have been widely used in the industry.Equipment successfully replace manual labor, metal processing with high accuracy.
19th century is rightly called the century of the "industrial revolution", railways and electricity.This century has had a tremendous influence on the world and the culture of mankind, changing its system of values.The invention of electric lights, radio, telephone, motor and many other discoveries turned human life at the time.
