Scientific advances and their origins

Since life first appeared on Earth, the world has seen many scientific advances. Some of the major advances include :

• The invention of writing :

  Found in archaeological findings in Mesopotamia, clay tablets were engraved for the purpose of communication over 5,000 years ago.

• Photogrphy :

  Based on the functioning of the human eye. In the 4th century BC, Aristotle, a Greek philosopher, discovered that light entering a dark room through a small hole projected onto the opposite wall the inverted image of objects placed in front of the orifice. That's the "Camera obscura" and this is what will later give life to photography.

• Space conquest :

  Neil Armstrong's first steps on the moon on 20 July 1969 were as exceptional as they were perilous.

Anecdote :

According to some studies, the first great discovery in human history was the domestication of the sheep in 9000 BC. This enabled prehistoric man to feed himself, create clothes, tools, etc.
