The Top ten Inventions of all time1.The Telephone

The telephone is an instrument that converts voice and sound signals into electrical impulses for

transmission by wire to a different location, where another telephone receives the electrical impulses

and turns them back into recognizable sounds. In 1875, Alexander Graham Bell built the first

telephone that transmitted electrically the human voice.

2.The History of Computers

There are many major milestones in the history of computers, starting with 1936, when Konrad Zuse

built the first freely programmable computer.

3.Television

In 1884, Paul Nipkow sent images over wires using a rotating metal disk technology with 18 lines of

resolution. Television then evolved along two paths, mechanical based on Nipkow's rotating disks, and

electronic based on the cathode ray tube. American Charles Jenkins and Scotsman John Baird followed

the mechanical model while Philo Farnsworth, working independently in San Francisco, and Russian

migr Vladimir Zworkin, working for Westinghouse and later RCA, advanced the electronic model.

4.The Automobile

In 1769, the very first self-propelled road vehicle was invented by French mechanic, Nicolas Joseph

Cugnot. However, it was a steam-powered model. In 1885, Karl Benz designed and built the world's

first practical automobile to be powered by an internal-combustion engine. In 1885, Gottlieb Daimler

took the internal combustion engine a step further and patented what is generally recognized as the

prototype of the modern gas engine and later built the world's first four-wheeled motor vehicle.

5.The Cotton Gin

Eli Whitney patented the cotton gin on March 14, 1794. The cotton gin is a machine that separates

seeds, hulls and other unwanted materials from cotton after it has been picked.

6.The Camera

In 1814, Joseph Nicphore Nipce created the first photographic image with a camera obscura,

however, the image required eight hours of light exposure and later faded. Louis-Jacques-Mand

Daguerre is considered the inventor of the first practical process of photography in 1837.

7.The Steam Engine

Thomas Savery was an English military engineer and inventor who in 1698, patented the first crude

steam engine. Thomas Newcomen invented the atmospheric steam engine in 1712. James Wattimproved Newcomen's design and invented what is considered the first modern steam engine in 1765.

8.The Sewing Machine

The first functional sewing machine was invented by the French tailor, Barthelemy Thimonnier, in

1830. In 1834, Walter Hunt built America's first (somewhat) successful sewing machine. Elias Howe

patented the first lockstitch sewing machine in 1846. Isaac Singer invented the up-and-down motion

mechanism. In 1857, James Gibbs patented the first chain-stitch single-thread sewing machine. Helen

Augusta Blanchard patented the first zig-zag stitch machine in 1873.

9.The Light Bulb

Contrary to popular belief, Thomas Alva Edison didn't "invent" the light bulb, but rather he improved

upon a 50-year-old idea. In 1809, Humphry Davy, an English chemist, invented the first electric light.

In 1878, Sir Joseph Wilson Swan, an English physicist, was the first person to invent a practical and

longer-lasting electic lightbulb (13.5 hours) with a carbon fiber filament. In 1879, Thomas Alva Edison

invented a carbon filament that burned for forty hours.

10.Penicillin

Penicillin was discovered by Alexander Fleming in 1928. Andrew Moyer patented the first method of

industrial production of penicillin in 1948.
