It is the greatest kitchen convenience in history. Before its conception, icehouses were used to provide cool storage for most of the year. The first refrigerator to see widespread use was the General Electric “Monitor-Top” refrigerator introduced in 1927.
People have been using glues of one form or another for thousands of years, so it’s hard to say who invented it first. These early glues were made from sticky natural substances like tree sap and the excretions of certain animals. However, the glue that you and I first think of when we hear the word was patented by a company in England in 1750. This glue was made partially from fish paste but was superior to that made from tree sap. The glue you and I use on a regular basis was invented by Ashworth Stull in 1942. The formula was sold to Borden and became known as the still famous “Elmer’s Glue”.
Let’s face it, if it’s not held together by a fastener of some kind, it’s held together by glue. Did you know that most of the shoes you wear are held together almost entirely by glues? The list of things for which glue is used is very long but it includes: toys, cars, computers, particleboard and plywood (your house probably wouldn’t exist without it), furniture etc.
We need to thank China for this one – the human history of toilet paper actually began relatively late. In the 6th century AD, wealthy individuals living in China often used paper for “sanitary” purposes – even though the standard paper making process had been perfected several centuries before. Regardless, there are several documents written by ancient scholars about the Chinese use of paper for toilet-related tasks.
Since almost the dawn of history, we have been using the wheel in some form or another. It’s been so long since it was invented, that no one knows for sure who the inventor was. Many historians think that the wheel must have been invented in somewhere in Eurasia since use of it was so much more prevalent and advanced there than it was in the Americas, even by the time that Europeans “discovered” the New World.
Most people today wouldn’t think of traveling further than a few city blocks without the help of wheels in some way (whether that be bicycle, car, motorcycle, bus etc.) Wheels are also the main form of the gears and pulley systems that allow so many devices to move. Even the CD/DVD tray of your computer wouldn’t open without wheels.
Today more than 1.7 billion people or 25 per cent of the world use the Internet. It is such a powerful invention that we’ve probably only begun to see its long term effects.
Even though we don’t really need the internet, it has many, many positives; we can learn about anything online and keep in touch with family and friends without having to rely on post
