The Story of the Bar Code
The ingenious ideas and technological advances that have led to the modern bar code.
A
The modern bar code, or more correctly, the Universal Product Code (UPC), has a relatively short history in the consumer world of some 40 years since its first working use, but the ideas that drove its introduction have been around for more than a hundred and twenty years. Indeed, earlier concepts of automated counting and identifying systems began in the late 19th century with punch cards being used in the 1890 U.S. census. In the 1930s, a student at Harvard University’s Graduate School of Business Administration headed a project designed to automate the shopping experience by using punch card technology from a catalogue to order items, which in turn would then see the items delivered from a storeroom with an accompanying ‘automated bill’. The idea being thus to keep more accurate inventory records, and, it was envisaged, to save time. However, the Great Depression and the unwieldiness of the system combined to ensure the project never moved forward. But, the ideas were in place; it was just a case of when the technology would be available.
B
The first moves towards the modern bar code began in the late 1940s in Philadelphia, in the U.S., at the Drexel Institute of Technology, when there was a request from the president of a chain of grocery stores to come up with the technology for an automated system to record product information during the checkout stage. The Institute declined to embark on the research, but a graduate student and a teacher at the Institute were intrigued by the concept, and began toying with different ideas as to how best to capture the required information. In fact, so intrigued was the teacher, Norman Woodland, that he quit his teaching job and moved to Florida to further advance the idea, experimenting and building on the concept of the Morse Code, with its dots and dashes, and converting them into a series of narrow and wide lines. It is recorded that one idea came to him while sitting on the beach, with his fingers in the sand, and as he pulled his fingers towards him, lines were created that would come to represent the basics of the system. He then swept his fingers in a circle, creating a bulls-eye figure, which was to serve as the basis for the first bar code design.
C
Norman Woodland continued working with the graduate student, Bernard Silver, and they were granted a patent in 1952 for their idea of a ‘Classifying Apparatus and Method’, an automated system of identifying and numbering different items, using symbols. However, academic analysis and peer evaluation identified the concept as being about 20 years ahead of its time, as the technology was lacking to put in place what the mind had conceived. There were no computers capable of handling the procedures, and an extremely bright light was required to ‘read’ the lines of the black and white coding system. By now Woodland was working at IBM, and was trying to interest them in pursuing the project but, while interested, IBM acknowledged that it was a project for the future. Woodland and Silver in turn sold the patent to another electronics company in an effort to stimulate industry action and in the early 1970s the RCA company had acquired the patent and began serious advances in realising the concepts. Unfortunately, Bernard Silver passed away at a young age in 1963 and never saw his original ideas come to fruition.
D
At the same time, in the late 1950s, there was a big move in the American railroad industry for a system to identify railway cars, which were moved all across America, and exchanged between different railway lines, thus creating a complex problem of keeping track of them. In the 1960s an MIT masters student named David Collins began working on a system with the then-new computers and he came up with a coding system utilising colour-coded stripes which would identify the owner of the railway wagon and its number, although this had its limitations. He quickly realised the implications of such a system and tried to persuade the company he worked for to expand the project and to develop ‘a little black-and-white-line equivalent for conveyor control and for everything that moves’. The company declined, instead choosing to focus on the railway system, so David Collins left and formed his own company, incorporating the new laser light system, one of the missing links that had bedevilled the earlier work of Woodland and Silver. In the late 1960s, some very basic systems were installed in motor car factories for General Motors and for a distribution company in New Jersey, to ensure shipments were sent to the right destination.
E
It was the grocery industry’s requirements that really propelled the bar code into universal use in the consumer world. In the early 1970s there was growing interest in the possibilities of the bar code, interestingly, for the original reasons that were initially put forward: inventory control and speeding up the check-out procedures. It was a lengthy procedure, though, to get everything running smoothly, and much was proceeded on based on faith that there would be long-term savings. In the future. In order for the system to produce the savings envisaged, upwards of 80% of all products would need bar codes, and the full cooperation of the production and retailing industry would be required. But time-lines were produced, and nearly every link in the consumer chain bought into the concept, and though there were figures presented that nearly $500 million would be required to get a thorough system in place, the guarantee of massive savings within ‘a few years’ drove the project forward, which saw the early concepts finally being put in place.
F
In 1974, in Ohio, in the U.S., a package of chewing gum was scanned at a supermarket and became the first retail product purchased using scanner technology. Scanning technology was now a reality, and the first scanner and the original pack of chewing gum are now on display at the Smithsonian Institute in the United States. Scanning technology then moved forward at a rapid rate, and today, the technology is used to track the mating habits of insects, health patients’ needs and identification, marathon runners in competitions, trees about to be cut down in forests, airline luggage and tickets, and an important tool in the reduction in fraud. Bar codes represent the ultimate in man’s ability to conjure up ideas, and then patiently work through the emerging technology to see the ideas realised fully.

The History of the Bar Code
The idea of the bar code began with the concept of which were used in the 1890 U.S. census, and experimented with in the 1930s. In the 1940s, grocery stores wanted an automated device that would capture for inventory records and to speed up the checkout process. Two men worked on the concept and one came up with an idea based on the Morse Code, and the first barcode was actually a design, shaped in a circle. At the same time, the Railroad companies were looking for an automated system to keep track of their , and a colour-coded numbering system was introduced, with the designer looking for a way to simplify it to black-and-white lines. With the invention of the light, the final innovation was made and in the 1960s, early bar code systems for inventory were introduced in car companies. The first retail product purchased using a bar code was in , and today bar codes are used for a wide range of purposes, as well as reducing .

Reading Passage 3
DWARF PLANET
The Discovery, Classification and Exploration of Pluto
A: On the 14th of July, 2015, a NASA deep space probe called New Horizons flew through the Pluto system in the Kuiper belt, located almost 6 billion kilometres from our sun, gathering high resolution photographs of the dwarf planet and its moons. Scientifically, the aims of the New Horizons mission were to provide experts on Earth with greater detail regarding the geomorphology, atmosphere, magnetosphere and surface composition of Pluto. As well as cameras for high resolution imagery, the spacecraft used an array of on-board scientific equipment to obtain information, including remote sensors, radio transmitters, computer subsystems, a large satellite dish and a radioisotope thermoelectric generator.
B: Pluto was discovered in February, 1930, by the American Charles Tombaugh, a young self-taught astronomer working at the Lowell Observatory in Arizona. Tombaugh, then in his early twenties, detected the existence of the planet by examining anomalies in photographic plates with the aid of a special viewing apparatus known as a blink microscope. His discovery soon made worldwide news headlines, and on the 25th of May, 1930, the members of the Lowell Observatory chose the name of Pluto for the ninth planet in the Solar System by unanimous vote. The name itself comes from that of the Roman god of the underworld, and was suggested by a schoolgirl living in England, whose uncle, a retired university librarian, had passed on her suggestion through academic acquaintances. It has been rumoured that Pluto’s discovery served as inspiration for Walt Disney’s canine character of the same name. There is, however, no question surrounding the naming of the element plutonium, which was named after the planet following the creation of the former by a team of scientists at the University of California in the early 1940s.
C: The estimated mass of Pluto was steadily revised downwards in the decades following its discovery, and was not accurately calculated until 1978, the same year in which Charon, the largest of the planet’s five moons, was discovered by the United States Naval Observatory astronomer James Christy. While the original estimate of Pluto’s mass had been seven times that of Earth, Christy and his colleague, Robert Harrington, compared Charon’s orbital period and size with those of Pluto, estimating the planet’s mass to be approximately 0.2 per cent that of the earth. A pair of smaller satellites, Nix and Hydra, was subsequently identified in 2005, with the final two of Pluto’s known moons, named Kerberos and Styx, being discovered in 2011 and 2012 respectively.
D: However, in spite of having been regarded as the ninth planet in the solar system for more than fifty years, Pluto’s status and classification began to come into question towards the close of the twentieth century. Initially, this was due to the fact that during the nineties a number of objects, made of rock and ice and of a similar size to Pluto, were discovered lying within the Kuiper belt, a circumstellar disc, in many ways resembling a gigantic asteroid belt, at the edge of the Solar System beyond Neptune. The first of these new Kuiper Belt Objects (KBOs) was identified in 1992 by a pair of astronomers, David Jewitt and Jane Luu, working out of the Mauna Kea Observatory in Hawaii. Many more Kuiper Belt Objects were found in the years that followed, making Pluto’s official status as a planet increasingly controversial among many in the scientific community. While Pluto remains, at present, the largest of the known trans-Neptunian objects located in the Kuiper belt, the discovery in 2005 of a minor planet with a greater mass, Eris, in an outlying region of the Kuiper belt known as the scattered disc, prompted the International Astronomical Union (IAU) to create a formal definition of the term “planet” that excluded Pluto.
E: When the New Horizons interplanetary space probe was launched from Cape Canaveral in January, 2006, its primary mission was to voyage to Pluto, at that time the only remaining unexplored planet in the Solar System. However, in August of the same year, at the General Assembly of the International Astronomical Union (IAU) held in the Czech Republic, Pluto was reclassified as a dwarf planet on account of the fact that it did not meet one of the three formal conditions required to be classed as a planet. According to the official definition of the IAU, a planet must be in orbit around the sun and have sufficient mass both for its own gravity to make it spherical in shape and to have cleared the area around its orbit of smaller objects. Failing to meet the third of these criteria, Pluto was classified as a “dwarf planet”. While the decision of the IAU to reduce the number of planets in the Solar System from nine to eight has received its fair share of both praise and criticism, the definition of Pluto as a dwarf planet, while controversial, remains in use. Today, there are five known bodies in the Solar System that have been recognised by the IAU as dwarf planets. In addition to Pluto, these are Ceres, Haumea, Makemake and Eris. At the same time, it has been estimated that there may be hundreds more as yet undiscovered and unclassified dwarf planets throughout the Solar System.
F: The high resolution images of Pluto made during the New Horizons close flyby of the planet and beamed back to Earth from across the Solar System have revealed a unique terrain. Far from being a flat, dead world, the rocky dwarf planet’s surface contains a multitude of varied, complex landscapes, ranging from oddly-textured ridges with the appearance of tree bark or dragon scales, ice cliffs, valleys and mountains and frozen lakes and oceans to heavily cratered and pitted plains. Experts theorise that, in addition to the impact of other space bodies colliding with the planet, the majority of its terrain has been shaped by a combination of ice sublimation and tectonic forces. While still awaiting official approval from the International Astronomical Union, names for a number of Pluto’s regions and topographical features have already been proposed by the New Horizons discovery team in consultation with the general public, including Tombaugh Regio, the Brass Knuckles, Tartarus Dorsa and Cthulhu Regio, the latter named after a fictional deity from the works of American author H.P. Lovecraft.
G: Irrespective of its official present classification as a dwarf planet, the New Horizons reconnaissance of Pluto provides a wealth of knowledge and data regarding the last major body in the Solar System not previously visited by a space probe. While the planet, spacecraft and New Horizons team may be comparatively small, the mission to the Pluto system not only represents the culmination of more than a decade’s worth of preparation on Earth, but also the beginning of a new chapter in space exploration at the edge of the Solar System and beyond.
