Some of the best inventions come from STEM

Some of the best inventions in STEM fields have seriously impacted history. Here are 6 STEM inventions that revolutionized our world.


Can you imagine what life would be like without wheels?  Trains, cars, bicycles, almost all forms of travel require this simple, but vital invention. Believed to be invented around 3500 BC, our ancestors have been enjoying the wheel for 5500 years.

Printing Press

When Johannes Gutenberg invented the moveable printing press in 1450, he unknowingly changed the world forever. The printing press allowed for an explosion of books and gave the general public access to new ideas. The printing press gave rise to the Enlightenment and the Protestant Reformation, forever changing the course of human history.


Cell phones today have developed well beyond the phone that Alexander Graham Bell used to make that first successful call on March 10, 1876. When Mr. Bell said, “Mr. Watson, come here! I want to see you!” he started the beginning of a communication revolution. The telephone, easily one of the best inventions in existence, radically changed communication and sped up the spread of information.

Light bulb

Growing up, we all heard the story of Thomas Edison inventing the light bulb. He tried thousands of different materials before finally patenting a working light bulb in 1880. “Genius is one percent inspiration and ninety-nine percent perspiration,” Edison said.


One of the first antibiotics, penicillin was discovered by Sir Alexander Fleming in 1928. During World War II, penicillin made a huge difference in the number of deaths among Allied forces, saving an estimated 12 percent to 15 percent of lives. Since it was discovered, penicillin has saved 82 million lives, and continues to be used by hospitals today.


Unlike the light bulb or the telephone, the Internet has no single inventor, but rather developed over time. In the United States the Internet first got its start as a government weapon in the Cold War. For years only scientists used it to share data. Today we use the Internet for everything from buying birthday presents to researching colleges to reconnecting with friends. Not only was it one of the best inventions for online shopping, it has also become a crucial part of everyday life.
