Recently I was ambling around the internet, researching lecture and article topics. I stumbled onto a Wikipedia site that at first seemed quite banal: Timeline of Historic Inventions. This link offered a chronological listing of historic inventions from the Paleolithic period, through the time of Christ, the Dark Ages, Middle- Ages and on to modern times. Perusal of the listing of inventors and their inventions was interesting on several levels.First was the attribution that could be applied by geography for the specific inventions. Cement in Egypt, rice in India, the Trebuchet in China and hundreds more hugely important inventions could be assigned as having originated in specific ancient lands. Many of these geographic locales are recognizable today, while many others, though identified, have been lost with the passage time and the disappearance of their historical importance.Second, many of the inventors are identifiable by name, even many of the most ancient ones. Attribution for creation of the encyclopedia is given to Speusippus, the odometer to Archimedes, the kite to Lu Ban, linguistics to Panini, and plastic surgery to Shushruta.Third, and most interesting, is the sheer volume of inventions, most of great import

1994 is a year that should be in the minds of all televisions lovers, as that was the year Directv began their revolutionary new service that would change satellite television to the widely loved and available phenomenon that it is today. For the first time, satellite viewers were able to use an 18 inch satellite dish and receive their transmissions in fully digital form. While most popular initially with rural folks who could not receive cable, even urban people soon realized that satellite television offered many advantages over what they had been watching. Directv presently has over 14 million customers experiencing the high technological quality and diverse programming that are only offered through satellite TV.To bring transmissions into your home, Direct TV has a fleet of high energy, photovoltaic satellites in a geosynchronous orbit around Earth. Hundreds of programming providers send their content to one of the company's broadcasting stations which then digitalizes and encrypts the signals and transmits them to the satellites. From the orbiting satellites far up in space the signals are relayed to individual satellite dishes with cutting edge technology ensuring perfect reception. Through the receiver, given to

And You Thought T-Shirts Were Not An Important Part Of American HistoryNine-one percent of Americans claim they own a "favorite T-Shirt".That, of course is no big deal...I have a favorite pair of socks, shoes, even salad fork.But there's more to the T-Shirt than meets the eye. There's important history and economics.The first promotional tshirt for a movie was printed in 1939. That movie was "The Wizard Of Oz". Like the movie, the tee did quite well. We make our own version of a Wizard Of Oz tee, I imagine a bit different than that first image, which shows a cartoon of the gang walking down the yellow brick road and Toto is lifting a hind leg. The caption reads, "How the yellow brick road got it's name." But I digress.T-Shirts account for important American economics. Cotton is still a huge industry in this country, particularly in the southern states. It takes six miles of yarn to make one T-shirt. An acre of cotton is enough to produce 1200 tees.Ever wonder if the T-Shirt business is a viable one? How about this for a statistic? About two billion tees are sold annually

Science and technology is the best thing society could ever ask for. Since the industrial revolution in the 18th century science has been in progress. Some sectors that have been boosted by science and technology are energy, physical sciences, information and communication. The society has greatly gained with the invention of technology.Infrastructure in the society has grown with the help of science and technology. Modes of transport like electronic railway lines were realized and these actually benefited the society by offering them a better means of transport. In the past, almost everything was analog but thanks to the science and technology we are now being digitalized by the day. The invention of the telephone and radio services has broadened human communication.Without society then there would be no science and technology and that is why the invention of certain tools and equipment have helped achieve big things. Society can not do without the industries we have today. The society needs science and technology. The creation of computers is work of art by individuals was a milestone that would come a long way in helping the society. A computer helps us to leverage

On a recent visit to Istanbul, I noticed a new structure in the historic Sultanahmet area where the Ayasofya, the Sultan Ahmet (Blue Mosque), the Hippodrome and several other imposing monuments are located. Some of these trace their history back to the 3rd century BC. The new structure housed the 1001 Inventions exhibition that traces the forgotten story of a thousand years of science from the Muslim world from the 7th century onwards, and how it was impacted by discoveries from other civilizations- the Indian, Persian, Greek and Chinese.On entering the exhibition I watched a film that showed the many technological feats that had been achieved in the Muslim world, including those that formed the precursors to modern day inventions such as the very film that I was watching. Ibn al Haytham, an eminent philosopher and mathematician observed light coming in from a small hole made in the shutters of a window. Further observation and experimentation led to the invention of the Camera Obscura, the first camera in history. This has led to the sophisticated digital imaging processes of today, including the making of films and their projection on screens, apart

This is one of our elementary science ideas where we are going to make a model of an erupting volcano. Before you make the model you have to explain what a volcano is and how your science project illustrates a real volcano. Even the most elementary science ideas have to be explained if it is to be of any use.So here are the questions you have to answer first: What are volcanoes? What do volcanoes produce? What makes a volcano erupt? How does your experiment explain it? As this is one of our elementary science ideas, we will not go into too much detail. The basics should be enough to make a small kid understand how it works.Here are the answers in short; if you want more detail it may be a good idea to look further: Volcanoes are placed where molten rock pushes up from below the earth through cracks in the crust of the earth. Contrary to what people believe, volcanoes do not only produce molten rock or lave, it also produces a lot of gases such as steam and carbon dioxide. Some of the gases are pushed into

Working in sports is no easy task, it requires an assortment of skills as well as your undying devotion. People who work in sports do not just enter the field because they just want some regular old job, but because they are passionate about the game and want to be around it all day everyday. Not all people however are meant to work in the world of sports but those who are posses in my opinion three essential skills to be successful in the business. Those three skills include communication skills as our business is fast paced and requires excellent communication, people skills as we are required to work and service an endless variety of people, and finally being proficient in the use of various computer applications and other computer software.As previously mentioned, communication is an imperative tool to have in the arsenal for someone who wants to work within the sports industry. This business requires you to be constantly communicating in every direction whether it is upward, downward, or lateral. This skill is particularly necessary for someone who seeks to work in the sales department of the industry. For example
