Who Invented the MP3 Format?

Who Invented the MP3 Format?...

The mp3 format was invented by the MPEG Group in 1991. The history of the mp3 format indicates several people worked on the project but the accredited inventors were Ernst Eberlein, Thomas Sporer, Karhl Heinz Brandenburg, Bern Grill and Bernd Kurten. Development Mp3 was the offshoot of OCF and PXFM. Those who worked on the project were mainly focused on how people were able to hear music. Through the course of their work, the Fraunhofer Society (which became part of the MPEG group) started looking for ways for music to be compressed and yet maintain its high quality. After working on it for several yeas, the standards were implemented in 1991. Further refinements would follow and it was integrated with MPEG 2 which came out in 1994. Release to the Public A study of the history of the mp3 format will reveal the Fraunhofer Society produced the encoder on July 7, 1994. A few months after its release, an mp3 player called Winplay 3 was released as well. Unlike other music formats, Mp3 offered a lot of advantages. The first was its small size. Using the 128 bit compression, a 5 minute song only came in at about 5 MB. This was a huge improvement over the WAV formats whose size was ten times that. In addition, the quality was very high, almost CD like. This became possible due to limitations in hearing. Mp3 removed the bits in the sound file that people wouldn’t be able to hear. By taking out these extraneous pieces, the size was reduced without sacrificing the sound quality. Popularity and Widespread Use Through the 1990s, the history of the mp3 format shows the tremendous impact it made on the Net. The release of Winamp...
Who Invented the Umbrella?

Who Invented the Umbrella?...

The long history of the umbrella makes it impossible to determine who invented it first. But there is strong evidence indicating the device has been used by many ancient cultures and civilizations. Ancient Middle East The word parasol was synonymous with umbrella during its early history. Archaeologists have discovered bas relief in Nineveh showing he parasol. It is held by a servant over the head of the king to protect him from the sun’s heat. Except for the connecting curtain, it looks a lot like the modern day umbrella. The Persians also employed the umbrella. Several sculptures have been unearthed showing attendants holding an umbrella over the king. The history of the umbrella goes back as far as ancient Egypt. The umbrella there assumed the form of a flagellum. This was a fan made up of palm leaves fastened on a long stick. Ancient Greece and Rome In 5th century Greece, the umbrella was frequently used by women. It wasn’t just used to shield them from heat; it was also a fashion accessory. Aristophanes notes that the umbrella (called skiadeion) could be opened and closed. Male Greeks rarely used the umbrella as it was seen as a female fashion accessory. It also had some religious significance as it was utilized in Dionysian rites. Roman writers like Ovid made frequent mention of the parasol. Even at this stage in the history of the umbrella, it was still used mainly by women. However it was employed mostly for fashion rather than protection from rain or heat. The Umbrella in Asia The umbrella was widely used in ancient China. There is evidence that umbrellas was had existed by 21 AD. The Chinese historians and writers at the time stated it was used...
Who Invented Boxing?

Who Invented Boxing?

Boxing is a martial art and combat sport which consists of two people who fight with their fists. Boxing is usually supervised by a referee and is separated into rounds, each rounds lasting from 1 to 3 minutes. There are only three ways in which a person can win a boxing match. One way would be to knock out their opponent. Also known as KO, knock outs are awarded once an opponent has been knocked to the ground and is unable to stand and continue the fight after a count to 10 seconds. Another way would be a TKO which stands for a technical knock out. This occurs when an opponent is deemed too injured to continue the match. The last way in which an opponent can win a boxing match is through a decision. At the end of all rounds judges or referee can award a winner based on several scores. History Boxing was first recorded in the 3rd millennium BC in which Sumerian reliefs depicted a fist fight with an onlooking crowd. Another similar relief was found in the 2nd millennium BC in ancient Egypt. In 1927 an archaeologist by the name of a Dr. E. A Speiser discovered a stone tablet from the Mesopotamian culture in which two men were depicted getting ready for a prize fight. The tablet is said to be more than 7,000 years old. Fist fighting with gloves was first seen between 1500 to 900 BC where a Minoan Crete was found which depicted two gloved men fighting. Homer’s lliad in 675 BC was one of the first detailed accounts of a boxing fight. The lliad states that Mycenaean warriors participated in boxing matches as a way to honor their fallen comrades....
Who Invented School?

Who Invented School?

A lot of people hate school. But lots more love it. It’s been around providing educational foundation for people. Both lovers and haters of it probably wonder who invented school. Or who started the idea of school? Byzantines or Hellenists? There are some suggested answers on the Internet, but they are far from being accurate about who invented school in particular. Most of them point to the Byzantines. They were said to be the first people on earth to come up with the idea of a school system. These people continued the Roman Empire in the Middle Ages. They were heavily influenced by the Greeks, especially in language. The Greeks were so dedicated in seeking knowledge. They had been known for this long before the Byzantines thought of a school system. Thus, some say they were the ones who invented school. But what Greeks had was a form of discipleship, not a school. There was an itinerant teacher with disciples. They traveled to places. They seldom met in permanent places. They conducted lectures in different locations and some local folks sometimes joined in to listen. There was no formality. So they were not the ones who started the idea of school. The Byzantines liked the Greek idea of teaching a following, but they preferred to have it in an enclosed permanent area and with a system. The Greek philosophers and their disciples talked about anything randomly under the sun. They often sought meaning in life. The Byzantines wanted more specific subjects dealt with at a time. Like Mathematics, Language, Philosophy, Religion, History, and the like. Thus, they’re considered the people who invented school. Who’s Horace Mann? To give a specific name to answer who invented school, some mention Horace...
Who Invented String Art?

Who Invented String Art?...

Introduction String art refers to a novel type of design that became popular in the 1960s. It is made up of colored strings bound together to form interesting geometric patterns and shapes. String art has its basis and origin in mathematics. One can design an endless variety of string art works. Invention and History of String Art Everest Boole It is not right to say it was just one person who invented string art. Several brilliant minds helped develop it. The first of them was a remarkable woman named Everest Boole. Boole laws an Englishwoman who lived from 1832 to 1916. She was self-taught in mathematics at a time when ladies weren’t considered very bright. When Boole grew up, she worked in the academic field and married a fellow math expert, George Boole. Boole was an innovative teacher. She was the first to suggest that string art can be used to teach math to children. Boole herself used it to teach geometry. With string art, it was possible to make lines with curves. Paul de Castejau Next was a French mathematician and physicist, Paul de Castejau. He wasn’t the man who invented string art. But he created the algorithm for what would be called Bezier curves. String art is based on Bezier computations. Pierre Bezier The name “Bezier” is familiar to computer graphics artists because of the Bezier curve. Bezier was a well-known inventor, engineer and mathematician. After graduating from the University of Paris, he found a job as an engineer at an automobile company. There Bezier’s math skills were put to the test. He had to find a way to describe each point on a curve to help with manufacture and design. This was long before the time...
Who Invented Bacon?

Who Invented Bacon?

A look at the history of bacon reveal that the word is likely derived from three sources. The French word bako, the Germanic word bakkon or Old Teutonic backe. All the words mean “back” in English, which is where bacon cuts are usually taken from. In the US the cut is from the pork belly. History During the Middle Ages bacon (or bacoun) was used to describe pork in general. It was around the 12th century that the phrase “bring home the bacon” originated. Legend says that a church in Dunmow, England promised to give bacon to any man who could swear to the church and God he hadn’t argued with his wife for a year. Thus, the man that was able to bring the bacon home to his wife was held to be a good individual. Whether this is really part of the history of bacon or not is uncertain. However the phrase has struck. The British and the Bacon By the 17th century, bacon had come to refer to the pork’s side cured with salt and not to pork in general. The Oxford Companion to Food refers to bacon as a product of the UK. Other accounts state that bacon wasn’t solely a British product. However the British system for making them was used in other countries. Other accounts say that preserved pork were part of the British diet for hundreds of years. By the 18th century, production of bacon in Britain had become widespread. According to some accounts of the history of bacon, John Harris of Wiltshire set up one of the first bacon curing shops in the country. The place has certainly become known for its production of bacon. Other Accounts Some claims that the...
Who Invented the Distance Formula?

Who Invented the Distance Formula?...

The man who invented the distance formula must have been amazed by distances. And why not? He was a traveler. He was a scientist and a philosopher always seeking the meaning in life. Aside from being educated in Greece, the distance formula inventor traveled other parts of the world to learn from other civilizations. Pythagoras Many acknowledge that Pythagoras was the person who invented the distance formula. He was from Samos and born around 570 B.C. He traveled not just to Egypt and Babylon, but also to Arabia, Phoenicia, Judea, and India. He did this in search of knowledge. According to records, he was much amazed by what knowledge was available in Egypt. He was also fond of experimenting with numbers and later on ended up being the distance formula inventor. Pythagorean Theorem Vertical, horizontal, or diagonal distance can be solved using Pythagoras distance formula, or what is called “Pythagorean theorem.” The man who invented the distance formula based this on the dimensions of a right triangle or a 90 degree triangle. This triangle has three sides—the base, the height, and the hypotenuse, which is the diagonal side. If 2 sides have known dimensions the third unknown can be solved. Thus, to solve the distance from one point to a standing structure, and the dimensions for the structure height and the hypotenuse are given, the distance can be calculated. The formula for this is C squared is equal to A squared plus B squared. According to the distance formula inventor, C is the value for the base, A is the value for the height, and B is the value for the hypotenuse side. The man who invented the distance formula figured any unknown value of this equation can be...
Who Invented the Car?

Who Invented the Car?

There is no straightforward and definite answer to who invented the car. In fact, the history of this modern day invention is quite rich with various inventors and innovators in between who made great strides in its development. The idea of developing or inventing a car dates way back during the renaissance era. Even then the thought of a horseless carriage wasn’t even thought possible by many. Early Origin of the Idea Though we can not say who invented the car we can give credit to the many inventors who put their ideas forward and contributed to the development of this modern invention. The idea of creating a car or automobile dates back to the 15th century. Leonardo da Vinci, other than painting the Mona Lisa, made many designs that were way too early for his day. One of the pioneer ideas of this renaissance icon is the design of a transport vehicle. The Idea Takes Form From this single design comes many types and further designs of our modern day automobile. There are countless types and styles to be found as the years rolled by and innovators came into the scene. Some of the types of cars you’ll find during the different stages of development include those that run on electricity, steam, or gasoline. Giving a definite answer to who invented the car will largely depend on the opinion of the person giving such a credit. Nicolas-Joseph Cugnot In the year 1769 Nicolas-Joseph Cugnot came in and made a self propelled vehicle for the French army. The vehicle ran on steam and was three-wheeled with a velocity of 2.5 mph. Robert Anderson In the years from 1832 to 1839 we find Robert Anderson of Scotland as having developed...
