INVENTIONS THAT CHANGED THE HUMAN LIFE

The first paper was created by Ts'ai Lun, a Chinese court official, in Lei-Yang, China. Ts'ai most likely made the thin mat by combining mulberry bark, hemp, and rags with water, pulverizing the mixture into pulp, pressing out the liquid, and hanging it to dry in the sun.

PAPER

COMPASS

The lodestone, on the other hand, was fashioned into a shape that is best compared to a soup ladle or spoon for the earliest compasses. The one seen here weren't made to be navigable. Primitive compasses helped people organize and harmonize their environs and lifestyles when they first appeared in China about the fourth century BC.

An Italian marine pilot named Flavio Gioja (fl. 1302) is frequently credited with developing the sailor's compass by dangling its needle over a fleur-de-lis pattern that indicated north. Additionally, he placed the needle within a tiny glass-covered box.

PRINTING PRESS

Around 1436, German inventor Johannes Gutenberg created the printing press. Its development was dependent on THE hand mold, a ground-breaking molding technique that made it feasible to quickly make large quantities of metal moveable type. Even while others, such as inventors in China and Korea, had done so before him, Gutenberg was the first to build a mechanized process that transferred the ink (which he manufactured from linseed oil and soot) from the moveable type to the paper.

STEAM ENGINE

The first known steam engine was the Aeolipile, which Hero of Alexandria describes in his book Pneumatica in the year 200 BC. The first steam engine that was practical for commercial use was unveiled in 1712 by Thomas Newcomen and his helper John Cally. James Watt, the inventor of the steam engine who is now known as its father, significantly increased the efficiency of stationary engines in the late 18th century when he developed a "double acting" engine that employed high pressure steam on both sides of the piston to double the output.

TELEPHONE

It was Scottish inventor Alexander Graham Bell who was the first to be granted a patent for the electric telephone on March 7, 1876. Three days later, Bell said in his first phone conversation to his assistant Thomas Watson "Mr Watson, come here — I want to see you." Bell’s inspiration for the telephone was influenced by his family. His father taught speech elocution and specialized in teaching the deaf speak, his mother, an accomplished musician, lost her hearing in later life and his wife Mabel, who he married in 1877, had been deaf since the age of five

PHONOGRAPH

Thomas Edison created the phonograph in 1877 by fusing the phonautograph, telephone, and telegraph. His objective was to write down telegraph messages on a sheet of paper tape. Then, the transcribed messages would be in a format that permitted the person to telegraph the same message repeatedly.

Edouard-Leon Scott created and received a patent for the first phonograph in 1857. On March 25, 1857, he filed a patent application for his invention, which he termed the phonautograph. The original innovation was able to record sound waves on a glass plate, but it could not play them back.

LIGHT BULB

Our reliance on natural light was removed by the development of the light bulb, which allowed us to be productive day or night. Several inventors contributed to the creation of this ground-breaking technology throughout the 1800s, but Thomas Edison is recognized as the primary inventor because in 1879 he developed a fully operational lighting system that included a generator, wiring, and a carbon-filament bulb similar to the one above.

AIRPLANES

George Cayley, a British engineer, created the first glider that flew successfully in 1853, but it wasn't until 1903 that Orville and Wilbur Wright's airplane made its first successful flight.

In contrast to many other aircraft inventions, it not only flew and landed without causing any damage after taking off from Kitty Hawk, North Carolina, using just its own power.

Watching birds in flight provided the Wright brothers with inspiration. The glider's design was inspired by bird wings, although it had a 32-foot (10-meter) wingspan instead.

COMPUTERS

Computers have been around for more than 200 years. Mechanical calculators were created in the 19th century to address the growing complexity of number-crunching problems, initially imagined by mathematicians and businesspeople. By the turn of the 20th century, technological advancements had made it possible for computers to become bigger and more sophisticated.

WORLD WIDE WEB

While employed at CERN in 1989, British scientist Tim Berners-Lee created the World Wide Web (WWW). To satisfy the need for automated information-sharing amongst scientists in universities and institutes around the world, the Web was initially designed and developed. The fundamental concept behind the WWW was to combine the rapidly developing fields of computers, data networks, and hypertext into a robust and user-friendly worldwide information system.
