SCIENCE BEST INVENTIONS:

1. FIRE - it can be argued that fire was discovered rather than invented. Certainly, early humans observed incidents of fire, but it wasn’t until they figured out how to control it and produce it themselves that humans could really make use of everything this new tool had to offer. The earliest use of fire goes back as far as two million years ago, while a widespread way to utilize this technology has been dated to about 125,000 years ago. Fire gave us warmth, protection, and led to a host of other key inventions and skills like coking etc.

 2. WHEEL - the wheel was invented by Mesopotamians around 3500 B.C., to be used in the creation of pottery. About 300 years after that, the wheel was put on a chariot and the rest is history. Wheels are ubiquitous in our everyday life, facilitating our transportation and commerce.

3. NAIL - The earliest known use of this very simple but super-useful metal fastener dates back to Ancient Egypt, about 3400 B.C. If you are more partial to screws, they’ve been around since Ancient Greeks (1st or 2nd century B.C.).

4. OPTICAL LENSES - from glasses to microscopes and telescopes, optical lenses have greatly expanded the possibilities of our vision. They have a long history, first developed by ancient Egyptians and Mesopotamians, with key theories of light and vision contributed by Ancient Greeks. Optical lenses were also instrumental components in the creation of media technologies involved in photography, film and television.

5. COMPASS - this navigational device has been a major force in human exploration. The earliest compasses were made of lodestone in China between 300 and 200 B.C.

6. PAPER - invented about 100 BC in China, paper has been indispensible in allowing us to write down and share our ideas.
