The Wheel and Axle

Janice Upton | June 2nd, 2019

It should be fairly obvious to most people that the invention of the wheel is extremely important to transportation. Without it, it would have been much harder for people to start traveling great distances or to move a large number of goods at a time. Imagine how hard it would be to construct a building without the usage of wheels to get heavy materials to the job site. Even vehicles that don’t necessarily roll across the ground use wheels, such as the mechanism that pulls cable cars around, or spinning propellers and engines that are used for flight.

However, it has been a lot more important to civilization than just being a method of getting from point A to point B. Many early machines and devices like the potter’s wheel, the water wheel, and the grindstone are also predicated on the invention of the wheel and axle. Gears and all of the indescribable amount of inventions that use them also employ this technology, so it is found everywhere.

It is believed that the wheel was invented towards the end of the Neolithic era, which took place about 12,000 years ago. The earliest applications seem to be in simple machines such as the aforementioned potter’s wheel, and evidence of them being used in vehicles wouldn’t occur until later in the Early Bronze Age, around 3100 BCE.

While the original wheels were much too heavy to be allow for faster travel, the invention of the spoked wheel allowed vehicles to be constructed lighter than they had ever been. This led to the creation of the chariot, as a solid wheel would have been too much of a load to pull for horses at high speeds. As time went on, they kept on getting lighter and sturdier, and are now used in almost all facets of life.
  • The Internet

    The infinite utility that the internet provides is easily evidenced by asking yourself how often you have referred to google or Wikipedia to ascertain information. Learning a new skill or troubleshooting a difficult technical problem before the web meant hours of research with written books, recordings, or even one on one sessions with an expert....

    Before the 20th century, infectious diseases killed an incredibly high number of people, resulting in extremely low life expectancies. In developed countries, life expectancy was below 50, a far cry of where those numbers are at today. There wasn’t an effective method that mankind could use against threats such as pneumonia, syphilis, and smallpox, and...

    Unless specifically trained to do so, humans are generally completely unproductive when they are unable to see. The reliance on sight all our lives as the main method to take in the world around us means that we are unable to function when that is taken away. The invention of different ways to carry around...

    Before the creation of the telephone or the telegraph, information that needed to be sent from one end of a country to the other necessitated a messenger to quickly deliver physical mail. In the United States for almost two years, this was achieved through the Pony Express. A relay of horse riders could deliver mail...

    Picture a world where knowledge and information had to be transferred from person to person by word of mouth or through hand writings. It would be much harder for humanity as a whole to benefit from any of the inventions mentioned in this article if that was the only method of spreading discoveries. Prior to...

    The earliest explorers and men who sailed on the open sea were well versed in astrometry, as they primarily had to rely on the position of the stars to navigate their way in the ancient world. This had several distinct disadvantages, as it required advanced knowledge of the way celestial bodies moved in the sky,...
