25 Most Significant Inventions In Human History

Our early ancestors must've looked up at the sky or at a flock of passing birds and must've wondered if such flight could be achieved by humans. Sadly, such a feat would have to wait until the dawn of the 20th century before it could be achieved.

Thanks to the drawing of Leonardo da Vinci and Sir Isaac Newton's theory of gravity, we've managed to defy one of the most powerful natural forces that worked against us since time immemorial, and we have mastered flight. From the Wright Brothers' 'Flyer', to the first war planes, to the first space ship, our brightest minds have managed to create an entirely new form of travel that doesn't just transport people and goods across the planet, but we have managed to leave the confines of our own planet and reach outer space.

Harnessing the science behind wings, aerodynamics and jet propulsion, among other things, has allowed for us to reach far away places that, a century ago, wouldn't have been thought possible. Now, it's possible to travel across the Atlantic Ocean in eight hours, and the planet is now surrounded by satellites that orbit the planet, with many more being launched on a regular basis.

In the early 1900s, it was said that every invention worth creating already existed. Never has there been a more inaccurate statement, as flight became such a significant accomplishment for humanity.
