I. HISTORY of INVENTIONS
the invention of crude tools, the ability to craft pottery, the invention of the wheel
The span of properly recorded chroniclers started with the development of writing and composition
- Machine age has resulted from a series of inventions: using of fossil fuels, the augmentation of metallurgical processes, the generation of power and invention of electronic appliances, internal-combustion engine, and the experimentation of metal and cement in construction work.
The American inventors Elisha Gray and Alexander Graham Bell applied for a patent on the telephone the same day.
- The atomic bomb was prepared during World War II (1939-1945) under the supervision of a team of leading scientists of many nationalities who instructed a much larger group of scientists and technicians intentions.
LEONARDO DA VINCI

painter Andrea del Verrocchio
Andrea del Verrocchio was a teacher of Leonardo. He made Leo an independent master
From 1495 to 1497 he produced a mural of 'The Last Supper'. Among the works created by Leonardo in the 16th century is the small portrait known as the Mona Lisa

- Bell went on to invent a precursor to the modern day air conditioner, and a device called a “photophone” that enabled sound to be transmitted on a beam of light and on which today’s fiber optic and laser communication systems are based.
NICOLA TESLA
Nikola Tesla was born on July 10, 1856, in Croatia.
Alternating current
Hydropower station
Engine. Tesla's AC Induction Motor is one of the 10 greatest discoveries of all time
Radio and radio control In 1892, Nikola Tesla created a basic design for radio.
IMPORTANCE OF INVENTIONS
Technology is very popular in our daily life thanks to its advantages. As we know, firstly, technology in household helps people do the housework.
. Nowadays people can travel faster and easier to other places by car, bus and air-plane, and see many new interesting things around the world.
Clear progress in medicine, use new technologies to diagnose and combat diseases make therapy more effective.
- It is almost impossible to go out without a mobile phone or an MP3 player, for example. These devices have become an important part of our life. Moreover, almost every day either a new technology is being invented or an old one is being improved.
