Who Invented the Alkaline Battery?...

An alkaline battery is a kind of a rechargeable battery or disposable battery that is dependent on the reaction between the compound manganese oxide and the element zinc. Many consumers prefer to use alkaline batteries over zinc-carbon batteries because alkaline batteries have longer shelf life as well as higher energy density. One of the most important materials used in the development of the batteries is the alkaline electrolyte of potassium hydroxide. Before we proceed with the characteristics of the battery, let us look at its history, including the person behind the invention of the alkaline battery. Historical Background Who invented the alkaline battery? The first alkaline battery was invented by one of the scientists of Energizer, Lewis Frederick Urry, in 1959. The prototype battery developed by Urry was displayed at the Smithsonian National Museum of History. In order to prove the durability of the battery, Urry installed the alkaline battery in a toy car and a zinc-carbon battery in another toy car. He raced the cars around a room. As expected, the toy car with the zinc-carbon battery was the first to stop. With the desire of the company to limit the use of mercury in batteries, it introduced the AAAA alkaline battery in 1989. Additional Information and Other Important Details An alkaline battery has a nominal voltage of 1.5 volts. To attain multiple voltages, it is important to make a series of alkaline batteries. When the battery was discharged, the zero-load voltage may vary from 1.5 volts to 1.65 volts. The voltage depends on the level of zinc oxide and manganese oxide in the electrolyte. Almost all alkaline batteries can be recharged. However, to do this successfully, there are some pointers to know. The first thing one should...
Who Invented Fencing?

Who Invented Fencing?

One of the most favored sports of sport enthusiasts is fencing. There seems to be an abundance of movies, TV shows, and sport events that actually feature and use this sport. Although that is the case, it seems that not a lot of those who like playing or watching this type of sport ever knew who invented fencing. So who invented fencing? Let’s check what history says. Earliest Points in History About 1200 B.C., there is evidence that fencing has been used before. This is supported by carving in the country of Egypt where a couple of masks, weapon protection tips, and judges were known to have existed. Also, during the early times of the Early Greeks and Romans, there are also some evidences that came up. These people were known to have a love for spears and short swords during their time. Also, it was said that during this civilization, chosen warriors learn their skills in schools that were called as ludi. Beginnings of Modern Fencing History says that it was during the fifteenth century when the origins of the modern fencing sport that we know now started to come into being. During the years 1471 and 1474, there were two of the first fencing materials that were published and distributed in Spain to those who are interested to know how to play this sport. During those times, there were also swordplay guilds spreading throughout Europe. In the 1500s, the use of the Rapier became more extensive and widely used by the Italians. The position involved using both hands with different weapons. As such, the person would be seen holding a particular weapon on the right and a small shield (also known as the buckler) on the left....
Who Invented the Elevator?

Who Invented the Elevator?...

Elevators make it possible to build skyscrapers even with a hundred floors or more. It must have been tough inventing something like that. But like other invented things, they started out simple—as a platform pulled manually. Who invented the elevator in primitive times, then? The first Inventor Elevators or lifts were used in ancient times. Historical records say they were used as early as the third century B.C. The first elevator inventor used raw human power to pull huge objects as blocks of stone using a pulley. There is no record of the man or men who invented the elevator that time, but sure enough the mechanical equipment was already in use then. Otis the Egyptian Egypt is among the first civilizations recorded to have been engaged in large-scale construction. An Egyptian probably was the one who invented the elevator. Otis was an Egyptian servant of Queen Elizabeth. He was said to be the one who invented the elevator. It was pulled using men or animals. Where water was available, water wheel was used. Archimedes’ Box Archimedes also built lifts for moving heavy objects up and down. But his were boxes, not just platforms. They were in popular use in the Middle Ages. Then in the time of King Louis XIV, the boxes were re-designed to carry people. Who specifically re-designed them was not mentioned, so Archimedes still could not be the one who invented the elevator for people. Otis the American In the 19th century Elisha Graves Otis introduced power elevators with safety brakes. Elevators then were powered by steam, which was a major breakthrough from the traditional manual operation. However, they were deemed unsafe due to cables that were susceptible to breakage. So Otis introduced something better:...
Who Invented the Toilet?

Who Invented the Toilet?...

The name Thomas Crapper is bound to come up whenever people discuss who invented the toilet. Sometimes it is given with serious consideration while others only take delight in the pun regarding his name. Thomas Crapper was a sanitary engineer who contributed to the design of the modern day flush toilet. However, it is interesting that there have been toilets in existence even thousands of years ago. Origin from Crete The earliest possible hint we have as to who invented the toilet dates back up to around 4,000 years into the past. There are those who theorize that an unnamed Minoan, which means a local of Crete, is the inventor of today’s toilet. However, an unknown and unnamed Minoan won’t give us who invented the toilet. At least we now know that as early as 2,500 B.C. seated toilets have been in use, which means that such toilets also had a drainage system. John Harrington Next among the theories on who invented the toilet comes John Harrington in the 16th Century. He was quite an unfortunate earl who angered Queen Elizabeth. Part of his works include a translation of Orlando Furioso, which was noted to have been done with both perseverance and skill. In relation to the question of who invented the toilet, Sir John Harrington published The Metamorphosis of Ajax, which is one of a trio of works that was published in succession in 1596. It contained the supposedly very first design of a water closet. Alexander Cumming The origin of the toilet takes another turn as Alexander Cumming comes into the scene. He is the first to patent a flushing device in 1775. His invention was a forerunner of the toilets we use today. Thomas Crapper He...
Who Invented Basketball?

Who Invented Basketball?...

Without a doubt, basketball is one of the most popular sports worldwide. The success of international sports groups and organizations like the National Basketball Association or NBA as well as the International Basketball Federation or FIBA has contributed to the overall popularity of the game. Likewise, the emergence of the Women’s National Basketball Association or WNBA gave women the opportunity to participate in this well-loved sport. In order to know the game more, it is good to know who invented basketball. The Invention of Basketball Who invented basketball? James Naismith was credited for the invention of this team sport some time in December 1891. He was at that time a YMCA Training School instructor in the City of Springfield in Massachusetts. His primary purpose for inventing the game was to give his students a vigorous indoor game to play especially during the extremely cold winter season. Additional Facts and Other Interesting Information At first, the game of basketball was played exclusively indoors. Before, a peach basket was nailed 10 feet high. Players usually shot the ball inside the basket in order to score. When a goal was made, the ball was to be retrieved manually. They solved this problem by cutting a hole under the basket in order for the ball to pass directly through it. The use of peach basket lasted until 1906. After that, it was replaced by backboards and metal hoops, just like in the basketball as it is today. The first official basketball game took place on January 20, 1892, which was held right inside the YMCA gymnasium. The playing field used then only measured half of the current regulation-size basketball court. The official score after that game was 1-0. After the game was invented,...
