I learned about four inventions this week and they were the safety razor, airplanes, the vacuum tube, and the Model T. First, I learned about the safety razor. King Camp Gillette, born in Wisconsin, in 1855, worked as a cork salesman and noticed that people bought disposable things. A safety razor is a shaving, protective device positioned between the edge of the blade and the skin. It allowed more men to shave at home because they were more confident they wouldn’t hurt themselves.

Second, I learned about airplanes. The Wright Brothers, born in 1878, focused on aircraft control systems and took experience from making bicycles. An airplane is an aircraft that is heavier than air that is propelled by a screw propeller or a jet. Airplanes helped people deliver crops and other items faster and more efficiently. It also allowed people to travel larger distances in shorter amounts of time and It could also hold more people instead of using steamboats and trains. 

Third, I learned about the vacuum tube. John Fleming, born in England, in 1849, wanted to be an engineer at 11 years old and worked at Edison’s company, then later at Macaroni’s company. An electronic device that controls the flow of electrons in a vacuum. The vacuum tube improved radios and computers. It led to CRT’s which made the TV possible.

Finally, I learned about the Model T. Henry Ford, born in Michigan, in 1863, learned how to maintain portable steam engines and built a quadricycle in 1896. The Model T was the world’s first car that gave families freedom to travel. It led to more cars being invented such as self driving cars, vans, limousines, trucks, and many more.

I learned about four inventions this week and they were the diesel engine, the mousetrap, the radio, and the semi automatic shotgun. First, I learned about the diesel engine. Rudolph Diesel, born in France in 1858, went to engineering school at 14 and began experimenting with ammonia engines. A diesel engine is an internal combustion engine which ignites fuel. It’s a great engine for heavy construction machinery and large generators.

Second, I learned about the mousetrap. Several mouse traps were built in the 1800s but William C Hooker invented the modern mouse trap. A mousetrap is a type of animal trap designed to catch and usually kill mice. A spring loads down and breaks the neck of a mouse.

Third, I learned about the radio. Marconi, born in Italy, in 1874, became interested in Hertz’s experiments. A radio transmits and receives electromagnetic waves of radio carrying sound messages. Radio broadcasting appeared in the 1930s and the internet has undermined this control.

Finally, I learned about the semi automatic shotgun. John Browning, born in Utah, in 1855, built his first rifle in 1878 and Winchester purchased a model from Browning. A semi-automatic shotgun is a repeating shotgun with a semi-automatic action. It established the modern handgun design and there also was the M2 machine gun.

I learned about four inventions this week and they were Coca Cola, induction motor, ballpoint pen, and the zipper. John Pemberton, born in Georgia, in 1831, was addicted to morphine after being slashed by a saber sword. He then experimented with coca wines. Coca cola is a sweet carbonated drink that contains caffeine from kola nuts. It originally contained cocaine. It led to the rise of soft drinks.

Second, I learned about the induction motor. Nikola Tesla, born in the Austrian Empire, in 1856, wanted to become an engineer and later worked with Edison’s company. Induction motors convert electric energy into mechanical energy. Rotating magnetic fields make it turn. Within 15 years electricity grew rapidly and it inspired the Tesla car company.

Third, I learned about the ballpoint pen. John J. Loud, born in Massachusetts, in 1844, was a trained lawyer but worked at a bank with his father, but was interested in genealogy and church activities. A ballpoint pen is a pen with a metal ball for the tip and uses two inks, oil based, and water based ink. The BIC cristal pen is the most popular pen in the world today because of the ballpoint pen.

Finally, I learned about the zipper. Whitcomb Judson, born in Chicago, in 1846, patented inventions in the 1880s, and was tired of buttoning his shoes. a device consisting of two flexible strips of metal or plastic that is closed or opened by pulling a slide along them, used to fasten jackets, bags, and other items. It led to the invention of the backpack in the 1950s.

I learned about four inventions this week and they were the light switch, skyscrapers, the dishwasher, and electromagnetic waves. First, I learned about the light switch. John Henry Holmes, born in England, in 1857, attended Swan’s demonstration who developed the early light bulb company. A light switch is a switch used to operate electric lights and can be turned on or off. It’s a simple but important invention and it led to other switch types.

Second, I learned about skyscrapers. William Jenney, born in 1832, in Massachusetts, learned engineering in France and fought in the civil war. A skyscraper is a tall building having multiple floors that can be 328 feet tall or more. Taller and taller buildings have been constructed every year since then. 

Third, I learned about the dishwasher. Josephine Cochrane, born in Ohio, in 1839, hosted large parties in fine China and wanted an easier way to clean dishes. A dishwasher is a machine that is used to clean dishes automatically.  Dishwashers save both water and energy, making it easier to wash dishes than hand washing. 

Finally I learned about electromagnetic waves. Heinrich Hertz, born in 1857, in Germany, studied engineering with Helmnoltz in Berlin and thought it was too difficult at first to prove Maxwell’s waves. Electromagnetic waves create a result of vibrations between an electric field and a magnetic field. The discovery of electromagnetic waves opened up a wide range of possible applications for electricity.

I learned about four inventions this week and they were the light bulb, the cash register, the thermostat, and the steam turbine. First, I learned about the light bulb. Thomas Edison, born in 1847, in Ohio, tried 3,000 different versions of the light bulb and tested 6,000 kinds of plant matter for filaments. The light bulb is a device used to convert electricity into light. It lit up New York in 1882 and there is a power industry thanks to Edison’s bulb.

Second, I learned about the cash register. James Ritty, born in 1836, in Ohio, opened a saloon which his employees were stealing from him. The cash register is a machine used in places of business for calculating money. It made it difficult for dishonest salespeople to steal.

Third, I learned about the thermostat. Warren Johnson, born in 1847, in Vermont, became a science professor at 34 years old and invented the thermostat in 1883. A thermostat is a device used to adjust heat and also is used with air conditioning systems. It led to the development of hot water heaters.

Finally, I learned about the steam turbine. Charles Parsons, born in 1854, in England, assisted in his father’s astronomical work and learned about shipbuilding and weapons manufacture. Steam turbines convert heat into rotation. Steam turbines are cheap power sources converted into electricity and now power everything we do.

I learned about four inventions this week and they were the telephone, the carpet sweeper, phonograph, and motion pictures. First, I learned about the telephone. Alexander Graham Bell, born in Scotland in 1847, was inspired by his mother’s deafness to study acoustics. Telephones allow people to talk to each other remotely. Federal government broke up AT&T’s monopoly in 1982 and then the baby bells merged back into each other.

Second, I learned about carpet sweeper. Melville Bissel, born in New York in 1843, opened own grocery store and then recession struck in 1873. Sweepers are mechanically powered vacuums that have brush roller and trash reservoir. Bissell’s sweeper led to the vacuum and then robots like roombas came along.

Third, I learned about the phonograph. Thomas Edison, born in Ohio in 1847, was trained by his mother to be a self learner. Today, the phonograph is called a record player. It marks waveforms into disc surfaces. It created the audio entertainment industry and vinyl records are still sold today. 

Finally, I learned about motion pictures. Edward Muggeridge, born in England in 1830, became a photographer in the 1860s. Motion pictures give fast moving images an appearance of motion and one movie is equal to 10,000 feet of the film. Hollywood was controlled by entrepreneurs of Christian movies and modern R-rated films assaulted.

I learned about four inventions this week and they were blue jeans, fire sprinklers, QWERTY keyboard, and the dental drill. First, I learned about blue jeans. Levi Strauss, born in 1829 in Germany, had his family enter the dry goods business and moved to San Francisco during the gold rush. Blue jeans are made from denim and are more durable than work pants. They are part of a cow boy uniform and sometimes are referred to as Levis. 

Second, I learned about fire sprinklers. Henry Parmalee, born in 1846 in Ohio, faced high insurance costs for his piano factory. Fire sprinklers activate automatically after it detects heat. Grinnel launched the modern fire protection industry and they reduce damage and repair costs.

Third, I learned about the QWERTY keyboard. Christopher Latham was a sholes editor in Wisconsin and improved the typewriter. The QWERTY keyboard optimizes typing speed and you can type 100 words per minute. It was very successful and the DVORAK layout was invented in 1936.

Finally, I learned about the dental drill. Before the dental drill, there was the clockwork drill and the air drill. Soon after, in 1875, George Green invented the dental drill. It was vital for fixing tooth problems and used in filling cavities. It changed dentistry forever and modern dentistry minimizes the pain.
