The primary difference between QR code’s and barcodes is that a barcode must be read horizontally, has a maximum storage capacity of 12 – 43 characters (e.g. universal product code etc.), and can store data in one dimension, whilst a QR code is capable of being read horizontally and vertically, has a maximum storage capacity of 4000 – 7089 characters, and can store data in two dimensions as a matrix bar code. Additionally, a QR code can be 10x smaller than a bar code and still be legible and a QR code can be read if damaged or parts missing. The term “QR code” is an abbreviation for “quick response code”
Tim Berners-Lee created the internet. Berners-Lee is the son of mathematicians, his mother and father part of a team who programmed the worlds first commercial stored program computer, the Manchester University Mark 1. Berners-Lee developed the original concept for the internet as a young boy, after discussing how machines might one day possess artificial intelligence with his father who was reading a book upon the human brain. Berners-Lee realized that if information could be linked, knowledge which would not normally be associated together, it would become much more useful. Ted Nelson helped expand upon Berners-Lee’s invention by developing the concept of hypertext, a method of digitally linking from one section to another. The development of the internet during the 1960’s became user friendly during the 1990’s as it became increasingly available to the public. Berners-Lee was able to take something which was too complicated for most people to use, and create a system which made it user friendly. Incompatibility between computers had been a thorn in the side of technology for years as specialized cables were needed to ensure computers could communicate with one another. Berners-Lee had the brilliant idea to create a centralized block which all cables would feed into so that one central unit could be used for every computer in the world to communicate. Berners-Lee furthered this idea by designing the concept of anything being linked to anything. A single global information space would be birthed as a direct result of this, a system with common rules, which would be accessible to everyone, that effectively provided as close as possible to no rules at all; a decentralized system. This arrangement would allow a new person to use the internet without having to ask anyone else. Anyone, anywhere, could now build a server and put anything upon it. Berners-Lee decided to name his creation the “World Wide Web” because he thought of it as a global network. Berners-Lee took his intellectual property and provided it to the public free of charge, despite having many commercial offers. Berners-Lee felt that the idea would not become the largest and greatest invention of humanity had it not been free, democratized, and decentralized. The fact that anybody could access the internet and anybody could put content onto it, made the internet massively popular early on and grew at a rate of 10x year upon year. Berners-Lee also created the World Wide Web Consortion, an institution which was designed to help the World Wide Web to develop and grow
Michael Aldrich was an English inventor, innovator and entrepreneur who in 1979, invented the concept of ecommerce, enabling online transaction processing between consumers and businesses. Aldrich achieved this feat by connecting a modified television set to a transaction processing computer which could process purchases in real time via dedicated telephone line. This system entitled “Videotex” had a simple menu driven, human to computer interface, which predated the internet by more than a decade. In 1980, Aldrich invented the Teleputer, a multipurpose home information and entertainment centre which was a combination of the personal computer, television, and telecom networking technologies. Aldrich created the Teleputer using a modified 14” color television which was connected to a plinth containing a Zilog Z80 microprocessor running a modified version of the CP/M operating system and a chip set containing a modem, character generator and auto-dialler. The Teleputer operated as a stand alone, color, personal computer during an era when computer screens were primarily monochromatic. The Teleputer contained software and networking capabilities using dial up or leased telephone lines. The Teleputer system itself included 2 floppy discs, each with 360 kilobytes of memory, later upgraded to a 20 megabyte harddrive, a keyboard, and a printer
The first ever computer generated sequence in a movie occurred in Star Trek II: The Wrath of Khan which lasted for 60 seconds and is referred to as the “genesis scene”. The scene includes a retinal scan of Captain James Tiberius Kirk as well as a planet being hit by a missile which then creates a stable environment for life. Over 50 software programs were written to accomplish this task and the creators of the sequence went on to form the digital animation company Pixar
Located in the heart of Paris, France, the Louvre Palace was the main place of residence for French monarchs during the 16th and 17th century, however in 1682, Louis XIV moved his entire court to the Palace of Versailles which was an even grander estate located in the countryside. The Louvre was then used to house Louis XIV’s immense private art collection. Today the Louvre remains as a museum housing some 40,000 works of art. The Louvre first opened to the public in 1793 as a direct result of the French Revolution. Napoléon Bonaparte was a master self-propagandist and understood the vast potential which the Louvre held to help promote his image. Bonaparte started filling the Louvre with numerous world famous artworks which he had seized as the spoils of war, from Egypt, Italy, and elsewhere. The Louvre was briefly named the “Musée Napoléon” which means the “Napoléon Museum” in French. The choice to change the name to the Musée Napoléon occurred in 1803 when the then director of the museum and a consummate courtier, Vivant Denon told Bonaparte that the museum should be named after the most glorious leader of France
The Cosmic Web is a scientific approximation of what the universe may look like at the largest scales, with massive clusters of galaxies linked together through vast filaments, with each containing trillions of stars. It would take light nearly 10,000,000,000 (10 billion) years to cross the distance of the Cosmic Web image
