The Lightswitch: Well with the lightbulb last time, I saw this coming. The lightswitch was very important in everyday life.
Before the light switch to turn on and off a lightbulb you had to do something very annoying. You had to get a ladder and unscrew the lightbulb to stop the circuit. Or re-screw the lightbulb to turn the light on. John Henry Holmes (1857-1935), invented the lightswitch in 1884. The light switch is very cool, it has an arm that is connected to the switch. The arm has wires that when in a certain position allows power to flow through. This power reaches the lightbulb and turns it on. When the switch is in the other position it breaks the circuit and stops the flow of power. If you listen very closely when you turn on the light, you may hear a click. That means the circuit is connected. Most light switches have an engraving on the switch that says on or off, depending on what position the switch is in.
I love the light switch, it is awesome. But un-screwing the lightbulb each time I want to turn on the light, that would get annoying. What if I had been using the lightbulb and it was hot, then it burnt my hand, ever think of that?
Skyscraper: Ooh, the skyscraper. We all know about the skyscraper, but did you know who, and how, it was invented?
As the human population became larger, it took more room to house all of them. But cities were running out of room, they needed buildings to go up not out. Well, it started to happen with steel, concrete, and the safety elevator. But the load-bearing walls needed to be thicker to hold the extra weight, but the first, second, and third floors of the building became smaller. That was bad, and everyone wanted a new way of holding up buildings.
Baron Jenney (September 25, 1832 – June 14, 1907), invented the skyscraper in a funny Eureka! moment. He was at home with his wife and they were moving some stuff around. Then Jenney’s wife put a very heavy book on a birdcage. The cage sat there like nothing was happening. So Jenney took the book off then dropped the book on the birdcage a bunch. He turned to his wife and said “This is it! This is how we do it!”. He invented the first skyscraper, which by nowadays standards weren’t very tall, only 10 stories tall. This allows humans to live in tall buildings, and allows cities to house more people since they could build up.
I would be fine if my first floor was small, It just needed enough room for a walkway and an elevator. I’d use the upper floors for everything else.
Dishwasher: Ok, maybe I can tolerate this. It actually is a bit sad, how it was invented. The inventor had a pretty sad life.
Before the dishwasher was invented it was really hard to clean dishes. You had to do them all by hand and that took a while, and was hard. People built a whole room dedicated to dish washing called the scullery. The floor was 4 inches then the actual house so if it flooded it wouldn’t ruin the house. The floors were also made of a waterproof material so that it wouldn’t get ruined. In front of the sink there were holes to let water out in case of a spill, or a flood.
Josephine Cochrane (March 8, 1839 – August 3, 1913), invented the dishwasher in 1886. Cochrane was wealthy, and she hosted parties a lot. She wanted a machine to wash dishes faster than her servants, and won’t break them. She measured the dishes first, then she made wire compartments, each designed to fit plates, cups, or saucers. Though only restaurants and hotels showed interest in the first 10 years. Her husband then died and left her with a bunch of debt, and she lost her wealthyness. But when the 1950’s rolled around, the dishwasher became a standard home appliance.
Personally the dishwasher is amazing, Our dishwasher broke once and we had to do everything by hand. Though, if my fancy china dishes broke because of one of my employees, I’d cry.
Electromagnetic Waves: This is not really an invention, so this section may or may not be short.
Electromagnetic waves are pretty cool, and are very important in everyday life. We use them in the radio, in x-rays, and many other things. This also lets us see colors, which is cool. Do you know how these waves are formed? They are formed when an electric field collides with a magnetic field, hence giving it the name ‘electromagnetic’. James Maxwell (13 June 1831 – 5 November 1879), came up with electromagnetic waves, but it was Heinrich Hertz (22 February 1857 – 1 January 1894), who proved that electromagnetic waves were real. The unit of frequency of a radio wave -one cycle per second- is named a hertz.
Sorry no silly comments here 😦 😦
P.S. If you leave a like I will send this to your house.
