Who Invented the White Board?

Who Invented the White Board?...

The history of whiteboards began in the mid 1960s. It’s still a mystery as to who actually invented it. Some think that it began in China, but there is no real way to be sure. The first company to mass produce porcelain on steel write on / wipe off whiteboard (called LCS) was Claridge Products. Whiteboards and Chalkboards The whiteboards evolved from the chalkboards (or blackboards). Although chalkboards were popular, some teachers and students were allergic to chalk. When material was wiped off from the boards, the dust would fly off. By the 1960s, early versions of the whiteboard began to appear. However the chalkboards were still popular. It was in the late 1980s that reports of chalk allergies became widely known, changing the history of whiteboards forever. The Evolution of the Whiteboard The early ones that came out were comprised of melamine. Not only was it costly, but excessive use left faint images of the material on it. Cleaning was also difficult. The enamel on steel write on / wipe off magnetic whiteboard was produced by Magiboards in Britain. In the United States, inventor Michael Boone helped popularized the Boone Board dry erase board. Improvements As the whiteboard became more popular, innovations and improvements from various companies emerged. Most important of these innovations was reducing the glossiness of the surface. This gloss resulted in glares which was distracting for students. The history of whiteboards shows that by the late 2000s, high quality paint coating was being used. This resulted in a very clear surface that was easy to write on. Whiteboard Surfaces Most whiteboards use any of the following types for their materials: melamine, painted steel, magnetic glass or porcelain. Melamine is the least costly and is also...
Who Invented the Stock Ticker?

Who Invented the Stock Ticker?...

It was in the year 1867 when Edward A. Calahan came up with the invention of the first stock telegraph printing instrument. But was Calahan noted as the first person who invented the stock ticker and was this model the very first product that came out? Or is there someone else who should get the credit? The Telegraph Years ago, Claude Chappe invented a non-electric telegraph that used a visual system. This optical system was created in 1794. After some time, with many modifications (like the invention of the Morse Code by Samuel Morse), the use of the telegraph widely spread. Companies were set up, and jobs were given to people who wanted to work for a telegraph firm. From Calahan’s Ideas to the Creation of the Stock Telegraph Calahan was working in the American Telegraph Company, then, when Calahan’s invention of the stock telegraph was created in 1867. Calahan thought that stock prices during those times could actually be produced through a form of telegraphy. And, thus, Calahan started to work on these ideas to create a very useful invention. When the invention was made, it produced an interesting sound that actually influenced its name, the stock ticker. Thomas Edison’s Part in the Invention Before Thomas Edison became known as the inventor of the electric light bulb, this inventor actually started as a simple telegrapher in younger years. After successfully improving the stock ticker model, Edison took on more challenging experiments to create more things. Edison’s invention was called as the Universal Stock Printer. For the creation of this improved model of the stock ticker, and other related creations, Edison was able to put up the first laboratory – albeit, small in size – and a facility for...
Who Invented the Periodic Table?

Who Invented the Periodic Table?...

The periodic table is a very significant set of scientific information that classifies the various properties of the different chemical elements. Specifically, it is widely used in chemistry, which is one of the most important academic disciplines. Its main purpose is to compare, systematize and classify the behaviors of chemical elements. Besides chemistry, it has a lot of role to play in other academic disciplines such as chemical engineering, biology as well as physics. The Invention of the Periodic Table Who invented the periodic table? In 1869, a Russian chemist named Dmitri Mendeleev invented this table to help show trends in the behavior of chemicals. According to many science historians, he has contributed a lot in other fields including geology, meteorology and hydrodynamics. Likewise, he also spent insurmountable amount of time studying different subjects under chemical technology such as fuels, petroleum as well as explosives. Add to that, he was credited for introducing the metric system to Russia. Additional Facts and Other Interesting Information As of July 2009, the total number of elements included here is 117, which is comprised of elements 1 to 116 and element 118. These elements are categorized into metals, metalloids and non-metals. The metals are further subdivided into various classes, namely alkali metals, alkaline earth metals, inner transition elements, transition elements and other metals. The alkali metals are francium, caesium, rubidium, potassium, sodium and lithium. Under the alkaline earth metals, you can find radium, barium, strontium, calcium, magnesium and beryllium. The inner transition elements are divided into lanthanoids and actinoids. The first group is comprised of lutetium, ytterbium, thulium, erbium and holmium. Additionally, it also includes dysprosium, terbium, gadolinium, europium and samarium. Of course, do not count out the remaining elements under this category,...
Who Invented the Trash Compactor?

Who Invented the Trash Compactor?...

There is no single inventor of the trash compactor. An assessment of the history of the trash compactor shows there are actually several inventions that led to the compactors as we know them today. The Earliest Trash Compactors Most machines use hydraulics to crush compress garbage. Using this definition of a trash compactor, the earliest patent would belong to M. S. Wells. In 1941 he patented an invention to compact oil cans. The mechanisms of his device are similar to the ones used by other trash compactors. This was followed by other inventions. The succeeding ones would improve or add features to the basic compactor. One well known patent is for the Kitchen Compactor. This apparatus was designed by one Mr. Boyd. A study of the history of the trash compactor will reveal that it adheres to the basic principles of trash compactors. In his application, Mr. Boyd declared the machine would use hydraulic pressure to compact trash. This apparatus had to be linked to the water line before it could be used. Boyd’s invention was for houses. That same year Stephen Hopkins came out with a trash compactor for apartments and offices. It did not need a water line to work. Instead it relied on electricity and an internal hydraulic unit. Both Boyd and Hopkins worked for the same company, Compackager Corporation. The Modern Trash Compactors The history of the trash compactor since the 1970s is noted for numerous improvements and innovations. The kitchen compactors today have noise reduction features built in. The pistons used in these devices have also become more powerful and more efficient. In addition, specially designed trash bags have been made for these compactors. Elements like sensors, pre determined pressures and load relievers have...
Who Invented the DVD Player?

Who Invented the DVD Player?...

The history of the DVD player and format is complex. But in simple terms, it emerged because the companies realized that a repeat of the Betamax / VHS rivalry would affect them financially. The first DVD players came out in November 1996 in Japan, developed by Philips. This invention can’t be attributed to one man. There is no clear data that say who exactly invented this device. Therefore, we can only say that Philips created the first DVD player. Other big companies started making their own players shortly after the Philips’ DVD player showed up. The first DVD player in the US was the Sony DVP S7000. It came out in March 1997. How the DVD Format Emerged In 1993, two formats were being touted to replace the CD. One was called the MultiMedia Compact Disc (MMCD). It was supported by Philips and Sony. The other format was the Super Density or SD. This format was backed by Toshiba, Pioneer, JVC and Time Warner. The SD group approached IBM and asked them to use the format for computer data storage. The MMCD group did the same thing. IBM decided to form the Technical Working Group (TWG) to resolve the situation. The group was composed of people from Microsoft, Apple and other major computer companies. In what would prove pivotal in the history of the DVD player, the working group managed to persuade the companies to use a single format. The MMCD and the SD were dropped; the DVD was adopted instead. As work on the DVD began, the companies decided to use technologies from both SD and MMCD formats. One of the technologies applied was EFMPlus, which made the disc more resistant to scratches and smearing. It also allowed...
Who Invented the Gatling Gun?

Who Invented the Gatling Gun?...

The Gatling gun is arguably one of the more famous and recognizable among all of the firearms ever made. Due to its distinct appearance and its unique capabilities, many are familiar with Gatling gun, even those who are not well-versed with firearms. Despite this familiarity even with the most gun-averse of laymen however, not many know who invented the Gatling gun along with the history of its design and development and its impact on modern warfare. As its name suggests, it is easy to remember who invented the Gatling gun. This because the man who invented the Gatling gun lent it its name. The man who invented the Gatling gun is Richard J. Gatling, an inventor responsible for numerous patents in the United States in the latter half of the 19th Century. Despite the Gatling gun’s fearsome reputation in the battlefield, the man who invented the Gatling gun reasoned his newly-designed gun will actually lessen the casualties in warfare. Since the Gatling gun will allow relatively few personnel to deliver tremendous fire power (for its time), less soldiers will then be needed to fight wars and therefore lesser battle casualties. Of course we all know that the idealistic notion of Gatling that fewer men will die in battle as a result of his invention’s tremendous fire power was baseless. But the man who invented the Gatling gun was in part right since for the first time in history, a few personnel with the help of his invention will be able inflict massive damage to the enemy. Battle before was mostly a man-to-man struggle between combatants but with the Gatling gun, a soldier can single-handedly inflict heavy casualties on the other side. More than a hundred years after its invention,...
