π What is Technology?
Technology is the use of scientific knowledge to create tools and machines that solve problems and make life easier. It includes everything from simple things like pencils and paper to complex systems like computers and the internet.
ποΈ The History of Technology: A Timeline
Let's travel through time and explore some key moments in the evolution of technology:
- π₯ Prehistoric Era: 3.3 million years ago - The Stone Age saw the invention of the first tools made from stone, wood, and bone. Early humans discovered fire, which was used for cooking, warmth, and protection.
- π± Ancient Era: 3000 BC - 500 AD - The invention of writing systems in Mesopotamia and Egypt allowed for the recording and sharing of knowledge. The wheel was invented, revolutionizing transportation and agriculture.
- π Medieval Era: 500 AD - 1500 AD - The printing press, invented by Johannes Gutenberg, allowed for the mass production of books. This led to the spread of knowledge and ideas across Europe.
- βοΈ Industrial Revolution: 1760 - 1840 - The invention of the steam engine by James Watt led to the mechanization of factories and transportation. The telegraph allowed for instant communication over long distances.
- π‘ 20th Century: 1900 - 2000 - The invention of the airplane by the Wright brothers revolutionized air travel. The invention of the computer and the internet transformed communication, information sharing, and entertainment.
- π± 21st Century: 2000 - Present - The development of smartphones, social media, and cloud computing has transformed the way we live, work, and interact with each other. Artificial intelligence (AI) is becoming increasingly integrated into our lives.
π‘ Key Principles of Technological Evolution
