Top 10 Inventions

I have made a list of what I would consider to be the Top 10 Inventions of time!

1. Knife
• When? Around 2.5 million years ago
• Why? Our ancestors were able to both hunt and defend with the knife. Knives were originally made from rocks and have within the recent few thousand years been advanced due to metallurgy. This tool easily has made the greatest impact on civilization.
2. Language
• When? Hot debate! No one knows for certain how long ago language first developed.
• Why? Language is a broad idea - this includes Latin, English, Chinese, and even math and music. Without language, our civilization struggled to communicate ideas, create organizational structures, tell tales, etc. Our ancestors grew more advanced by creating the opportunity to use language in order to delegate tasks and pass down moral lessons.
3. Wheel
• When? 5000 B.C.
• Why? The wheel has revolutionized the way humans traveled and transported various goods. It is a great invention because the only naturally occurring round shapes are at the microscopic level; therefore, this is no humble invention.
4. Sewage System
• When? 3500 B.C.
• Why? The development of this piping system eliminated wastes from cities, decreased the spread of disease, and ultimately brought sources of clean water as the technology advanced.
5. Antibiotics
• When? 1928 by Alexander Fleming
• Why? Fleming made the discovery that penicillin can kill the staphylococci bacteria. This discovery has opened grand avenues for drug treatment and aided in prolonging human life.
6. Contraceptives
• When? 1564 "by" Gabriello Fallopius. Although the idea of contraceptives has been around since the start of man, Fallopius officially developed the male barrier method.
• Why? Contraception has reduced the transmission of venereal disease and aided in family planning.
7. Light bulb
• When? 1879 by Thomas Edison
• Why? After the discovery of electricity by Thomas Jefferson, a great invention was the incandescent lamp. The illumination of the night increased productivity by allowing us to work at night, decreased fire hazards from fire-lit candles, and helped reduce crime rates in the streets.
8. Telephone
• When? 1870 by Elisha Gray/Alexander Graham Bell
• Why? The telephone transformed communication, bringing forth immediacy and the start of efficient globalization.
9. Genetic Modification Technology
• When? 1973 by Stanley Cohen and Herbert Boyer
• Why? The invention of DNA cloning has led to our ability to genetically modify organisms, perform gene therapy, clone animals, and sequence the human genome. This allows us to work on eliminating genetic diseases and prolonging human life.
10. The Internet
• When? Around the late 1950's the Internet began to form through a collective effort
• Why? The Internet has drastically changed the way we carry out day-to-day tasks, run businesses, and has unprecedentedly globalized our world.
