Impact:

Allowed people to work and read at night
Boosted industrial productivity
Transformed cities with street lighting

Edison’s invention laid the foundation for modern electricity use in homes and industries.

2. The Airplane – Wright Brothers (1903)

Orville and Wilbur Wright made human flight a reality with their first powered airplane in 1903. What started as a 12-second flight in North Carolina became the beginning of the modern aviation industry.

Impact:

Shrunk the world by reducing travel time
Revolutionized global business and tourism
Played key roles in defense and disaster response

Thanks to this invention, flying across countries and continents became a part of modern life.

3. The Internet – Vinton Cerf and Others (1970s-1980s)
