The first invention I learned about was Portland cement. It started with Joseph Aspdin patenting a new formula for cement that he called Portland. It was named after a British Isle, Portland. Joseph modified his fathers formula of cement. Portland cement has great strength, so it is the most popular in the world. His invention impacted history because most modern structures rely on concrete that uses Portland cement.
The second invention I learned about this week was electromagnets. William Sturgeon invented the electromagnet after Oersted discovered the link between electricity and magnetism. Electromagnets use magnetic fields produced by electric currents to turn ferromagnetic materials into strong magnets. The invention spread quickly as others became fascinated by the idea. No one had seen anything like it before. Electromagnets are behind some of the most popular devices that are used today. Such as powering speakers.
The third invention I learned about was the Passenger Rail. A growing fascination with high pressure steam lead to the invention of locomotives in 1801. George Stephenson invented the passenger rail. George’s success grew the industry, and he trained Americans on how to build successful railroads. The passenger rail provided a rapid transport that quickly carries people efficiently to their destinations. The railroad had a big impact on Great Britain and America, helping to bring about the most rapid economic transformation in history.
The last invention I learned about was the match. The match was invented by John Walker. Matches were almost invented by accident by John. He never patented his design, because he never needed the money. Matches work by simple chemical heads embedded on a stick. The match helped make smoking become easier. It also let us use the grill and barbecue more leisurely.
The most interesting thing I learned about this week is how you can make your own electromagnet. All you need is a battery, some copper wire, a nail, and the last thing you need is some metal objects. I found it interesting because it is not even a real magnet, and it still acts like one. You can also make it out of everyday objects.
