- Compass (China): Enabled navigation and exploration across oceans.
- Printing Press (Johannes Gutenberg, 1440): Sparked the knowledge revolution and made books accessible to the masses.
- Telescope (Galileo Galilei, 1609): Opened the doors to astronomy and space science.
- Steam Engine (James Watt, 1769): Paved the way for the Industrial Revolution.
🔹 19th Century Scientific Breakthroughs
The 19th century marked a period of rapid industrialization and innovation. Some major inventions included:
- Electric Bulb (Thomas Edison, 1879): Illuminated the world and changed human lifestyle.
- Telephone (Alexander Graham Bell, 1876): Revolutionized communication.
- Radio (Guglielmo Marconi, 1895): Brought the world together through wireless communication.
- Photography and Cinema: Gave rise to visual storytelling and entertainment industries.
- Periodic Table (Dmitri Mendeleev, 1869): Organized chemical elements, forming the basis of modern chemistry.
🔹 20th Century Inventions – The Age of Science & Technology
The 20th century was the era of scientific revolution—shaping modern civilization through unprecedented innovation:
- Airplane (Wright Brothers, 1903): Changed global travel and warfare.
