It is a mechanical device for applying pressure to an inked surface resting upon a print medium (such as paper or cloth), thereby transferring the ink. Typically used for texts, the invention and global spread of this invention was one of the most influential events in the second millennium.
It's the most commonly used system of writing by and for blind people. Named after its French inventor, it is a code of 63 characters.

It is the technology of signaling and communicating using radio waves which are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). Radio waves were first identified and studied by German physicist Heinrich Hertz in 1886. The first practical radio transmitters and receivers were developed around 1895–1896 by Italian Guglielmo Marconi, and radio began to be used commercially around 1900.
The problem of how physical laws and measurements change hen considered by observers in various states of motion. They change depending on how fast you're moving. These theories forced the revision of all fundamental thinking about time and space.
It is a circular component that is intended to rotate. They were invented in Mesopotamia about 5,500 years ago. They were first used as potter's wheel.
It's the most famous painted interior spaces in the world. It was painted between 1508 and 1512, and it is a cornerstone work of High Renaissance art.
GPS is a highly accurate satellite-based navigation and location system. The Navtar GPS system was developed by the US military. Battlefield missiles and artillery projectiles use GPS to determine their positions and velocities.
It is a tabular display of the chemical elements created by Dmitri Mendeleev. It is a graphic formulation of the periodic law, which states that the properties of the chemical elements exhibit a periodic dependence on their atomic numbers.
Completed in 2003, the HGP mapped every gene in the human genome. It was an international scientific research project with the goal of determining the base pairs that make up human DNA.
The trio of astronauts that led the Apollo 11 mission were Neil Armstrong, Edwin "Buzz" Aldrin and Michael Collins. Neil Amstrong stepped on the Moon on 20 July 1969.
