The modern world owes many of its conveniences to the many scientists and inventors that came before. Their ingenuity allowed people to communicate faster, travel further, and gain knowledge at a greater level. Civilization cannot be what it is today if it weren’t for them.

Take Alexander Graham Bell as an example. He developed the telephone, which connected people to each other even if they were physically far away. Now, that technology has evolved into the smartphone and the internet, allowing people to keep in touch anywhere and anytime, instantly.

Thomas Edison is another such genius. He perfected the light bulb, and thanks to that, nights no longer have to be pitch black. People can see in the dark and light up their houses in the evening thanks to the light bulb. Similarly, this device has evolved to use less electricity and last longer.

How about Alexander Fleming, who discovered the antibiotic called penicillin? Before antibiotics existed, many people died of infections like leprosy. However, once antibiotics became widespread, such diseases became easily curable. Afflictions that were once thought to be deadly could now be easily treated quite effectively.

How people benefit from some scientists is not always obvious, though. Take a look at Albert Einstein and his theories of relativity. Who would have thought that those concepts can be applied to GPS satellites? Without taking relativity into account, the location readings on people’s phones would be way off by miles. Another example is Erwin Schrödinger’s models of quantum mechanics, which are now used to design so-called quantum computers that are capable of much faster calculations than traditional computers.

Especially in this modern era, scientists will continue to shape the world we live in. Their discoveries and inventions will keep on making the world a better place to live in. A scientist’s job is noble, and his contributions will be enjoyed by many people for generations to come.
