Science is a subject that explains the world around us. Its laws govern the very fabric of the universe, everything that happens – from falling objects to celestial explosions. Today, science has changed our lifestyle to such an extent that life would be hard to imagine without it. Things we take for granted, such as electricity, is the result of careful analysis and implementation of something that already existed in nature. From Newtons Laws of motion to Einstein’s Theory of Relativity, science evolved from an unexplored subject plagued with superstition and mystery to a vast, systematic,multi-disciplinary field.
Prior to steam engines, work was done through manual labour or through animals. Ships relied solely on the power of wind, transportation involved carriages pulled by horses. The invention of steam engines changed all that. Power was consistent and reliable. Many other inventions sprung up to harness this new energy source. Today, steam engines are rather outdated, but they helped pave the way for modern technologies.
Since time immemorial, man has dreamt of flight, with many inventions trying to mimic the flight of birds. With the advent of science, man was able to create contraptions that were able to get off the ground – momentarily. But it wasn’t until 1903 that the Wright Brother were able to invent the first powered flight. It had a total flight time of just 59 seconds. Just 50 years after, we sent the first rocket into space.
This device was responsible for discovering a whole new world of microorganisms which was right under our noses. The credit for this invention is still disputed, but much historical evidence point towards Zacharias Janssen and Hans, a father-son team from Middelburg, Netherlands. That microscope was theorized to have a magnification power of 8x-10x. Today’s modern electron microscope has a magnification power of 10,000,000x. This is possible due to the application of concepts like Electric potential. Learn more interesting concepts in science by visiting BYJU’s website.
