Who Invented Numbers?

Numbers or symbols used for counting have existed since man learned to count. Archeologists and historians estimate that numbers were first used around 32,000 years ago. They base this theory on archeological findings such as bones and rocks with marks on them. These may have been counting or tally signs used to keep track of time or quantities of objects, such as food or livestock. Simple Systems The very first number system must have been a tallying system. Tallying systems have no complex symbols or place values. It is the simplest counting system though not practical for dealing with large quantities of number. Our modern number system has 10 as its base or place value. A place value simplifies number representation and counting. Another simple number system was the ordinal counting system. It is thought to have started when man began counting with his fingers, each finger standing for a unique number. Place Value Systems A couple of ancient civilizations invented number systems with place values. The oldest was the Mayan system with 60 at its base, around 3400 BC. The Egyptians invented a 10 base system in 3100 BC. The modern place value system also has 10 as its compression figure. It came from India by way of the Arabs. Invention of Number Zero The number zero was used by various peoples including the Mayans, Egyptians, Babylonians and Indians. The Egyptians used zero in their accounting records. The Indians referred to zero as “the emptiness.” The inquisitive Greeks were puzzled by this figure and developed many interesting philosophical views on the subject. In fact, occultists and mystics used the number zero to symbolize the nothingness, or void state of things. Invention of Negative Numbers The Chinese invented numbers...
Who Invented Jazz?

Who Invented Jazz?

Even the most ardent student of the history of jazz will be hard pressed to trace its inventor. Rather than point to a single individual, it’s more accurate to say that the sound emerged from various musical sources. Beginnings of Jazz Music Some accounts state the word jazz was first heard in Chicago. It is unclear where it came or from what it was derived from. Its origins have also been disputed. Some claim the music originated from Africa. This influence can be seen from some common elements found in jazz. These are improvisation, swung note and polyrhythm among others. But most accounts of the history of jazz trace its roots in the 1890s. Black people in America were given the chance to hold jobs. Segregation was still enforced. But they were able to find work as entertainers. Blacks worked at vaudeville, minstrel and other musical shows. Various forms of music remerged including ragtime and the blues. From these and other genres, jazz would come out. The 1900s to 1920s It was during this time that jazz as we know it came into being. It became very popular in New Orleans. Most of the early jazz musicians played in the red light district of New Orleans. One of the earliest known jazz musicians was Buddy Bolden. He began playing in 1900 and is considered by many as the first man of jazz. The 1920s saw the arrival of the phonograph and radio. These two innovations had a tremendous effect on the history of jazz. Once limited to the south, their music was now heard across the country. Bessie Smith became known as the Empress of the Blues and the most well known singer of the 1920s. Other performers during...
Who Invented Lip Gloss?

Who Invented Lip Gloss?

Primarily a cosmetic product, the purpose of lip gloss is to provide the lips with subtle color, glossy luster and mild texture. Aside from clear color, it is also available in a variety of shades, some of the most popular of which are the metallic, glittered and frosted. Constant use of this product can lead to softer, well moisturized and younger looking lips. In addition to these interesting details, it is also good to know who invented lip gloss. The Invention of Lip Gloss Who invented lip gloss? The first ever product that resembled modern-day lip gloss was released by the cosmetics company Max Factor. It was launched some time in 1932 as part of the cosmetic product line named X-Rated. Since then, it became a perfect alternative for lipstick. It provided users with a wet, sexy and kissable look without the heavy feeling of wearing lipstick. The original formula lasted until 2003. By that time, Procter and Gamble had already acquired the rights to the product line, which eventually decided to stop its production. Additional Facts and Other Interesting Details Today, lip gloss is available in different forms. Some of them are available in small cylindrical containers, while others are contained in small tubes. While some are to be applied directly to the lips, others are applied using the fingertips. In recent years, the original formula has encountered a number of improvements. Modern-day lip gloss features ingredients that can make the lips look plumper and softer. They serve as perfect alternatives to fat injections, Juvederm and collagen. However, their effects are last only for a short time. Good thing they are harmless, easy to use and cheap. Nowadays, it is not only used as a cosmetic, but also...
Who Invented the Flash Drive?

Who Invented the Flash Drive?...

Introduction The USB flash drive is a tiny storage device that uses flash memory. It connects to a computer via a USB port. A flash drive is usually portable and rewritable. A single device can store anywhere from 64MB to 256GB and more depending on the model’s capacity. Because flash drives are so small and portable, they are ideal for carrying data while on the road. They can also be used to transfer data between two computers. Invention of the Flash Drive In the early days of the computer, things were much simpler. Files were small in size, so floppy disks were enough to store them in. But as computer technology advanced, so did the types of files used. Now floppy disks could only hold 1.44MB of data at a time and they were very slow. There was a need for a better portable storage device. It was IBM and Trek Technology who invented and sold the first USB flash drives in the year 2000. Trek Technology was a Singaporean company. They dubbed the new invention as a “thumb drive” because its size was roughly that of a thumb. In the US and Canada, IBM marketed a flash drive called “Disk On Key” which was made in Israel. The first flash drives had capacity of only 8MB. But this was already a huge leap from the 1.44MB capacity floppy disks in use at that time. Benefits of the Flash Drive The flash drive fulfills the same role as floppy disks, CD-RWs and other removable storage devices. They can be used to back up or transfer data. Floppy disks are now obsolete with new computers rarely carrying them. CD-RWs and other rewritable media are slower and more fragile. Flash drives...
Who Invented Paper Money?

Who Invented Paper Money?...

The use of paper money is one thing that most of us take for granted. That is to be expected of course since everything that we do in our daily lives involve, in one way or another, the use of paper money. This is why it is hard to imagine a time when money exclusively refers to coins since the use of paper as a form of currency came in a much, much later era. This makes the question of who invented paper money an unlikely query in most people’s mind. But with its importance, it is definitely a good thing to know who invented paper money. Who invented paper money? This is not a simple question to answer as paper money is unlike other tools that came to be thanks to an inventor who designed and made them first. This is because the use of paper money is not pioneered by a single individual. Rather, the use of paper money was first used by a group of people who realized that using coins was cumbersome since accumulating great amounts of it will provide one with difficulties, particularly with transporting the huge amounts from place to place. So who are this people who invented paper money? The pioneering use of paper money is widely credited to the Chinese, who used it around 650 AD. Asking who invented paper money will also inevitably lead one to another important question: why? The use of paper money began when people decided to deposit their large sums of money (which were all in coins) in vaults owned by enterprising individuals who make a profit safeguarding other people’s riches. In return, depositors get promissory notes from these enterprising individuals indicating the amount of money...
