10 The discovery of 'Change' World

1. "Telephone"

The telephone is an instrument that converts voice and sound signals into electrical impulses for transmission by wire to a different location, where the recipient the electrical and converted For telephone can be heard by the recipient. In 1875, Alexander Graham Bell built the first telephone that mengkirimkan human voice over electrical.

2. Computer

There are some important milestones in the history of computers, starting with 1936, when Konrad Zuse built the first computer that freely programmable.

3. Television

In 1884, Paul Nipkow sent images over wires using a rotating metal disk technology with 18 lines of resolution. Television then evolved in two ways, using a mechanical based on Nipkow that rotating disk, 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 émigré Vladimir Zworkin, working for Westinghouse and later RCA, advanced the electronic model.

4. Car

In 1769, the first self-propelled vehicle on the road itself invented by French mechanic, Nicolas Joseph Cugnot, who used steam engines. In 1885, Karl Benz designed and built the first practical automobile powered by an internal-combustion engine. in 1885, Gottlieb Daimler took the internal combustion engine a step further and patented what is recognized as the prototype of the modern gas engine and later built the first four-wheeled motor vehicles in the world.

5. The Cotton Gin

Eli Whitney patents cottong 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. Alata cotton gin is a machine to separate the grains, and other unwanted hulls to produce cotton.

6. Camera

In 1814, Joseph Nicéphore Niépce created the first photo with a camera obscura images, but the images required eight hours of light exposure and pictures disappear over time. Louis-Jacques-Mandé Daguerre is considered the inventor of the first practical photographic process in 1837.

7. Steam engine

Thomas Savery was an English military engineer and inventor who patented the first crude steam engine in 1698. Thomas Newcomen invented the atmospheric steam engine in 1712. James Watt improved Newcomen's design and invented what is considered the first modern steam engine in 1765.

8. Sewing machine

The first finding a functional sewing machine was 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 movement of the mechanism. In 1857, James Gibbs patented the first chain-stitch single-thread sewing machine. Helen Augusta Blanchard memateni sewing machine zig-zag stitching in 1873.

9. Bulb

Contrary to popular belief, Thomas Alva Edison did not "invent" the light bulb, but it improves the idea 50 years earlier. 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 days.

10. Penicillin

Penicillin was discovered by Alexander Fleming in 1928. Andrew Moyer patented the first method of industrial production of penicillin in 1948
