Barcodes


Barcodes



When you checkout from a supermarket, the person at the counter checks all that you have bought by flashing a small light at a set of lines marked somewhere on every item. How does this system of checking work?
A barcode is machine-readable information. It allows data to be collected accurately and rapidly about the product such as what product it is, the country where it was manufactured, prices, stocks left and so on.
A Barcode symbol consists of a series of parallel bars and spaces. Each of these wide and narrow bars and spaces in the pattern represents a character which in turn represents some kind of a code. Such as, numbers 00-13 is the country code for USA and Canada, 45 for Japan and 890 for India.
How is the barcode read?
A barcode reader uses a scanning device which is basically a photo sensor. It measures the relative widths of the bars and spaces, translates the different patterns back into regular characters, and sends them on to a computer or portable terminal. Here the original data is recovered. A bar code works like a light when turned on in a dark room. You see the walls and furniture in the room by the light reflected from these items.
The scanning device contains a small sensory reading element. This sensor detects the light being reflected back from the bar code, and converts the light energy into electrical energy. The result is an electrical signal that can be converted into data. Scanners employ various technologies to “read” codes. The two most common are lasers and cameras. Scanners may be fixed position type or hand-held devices.
History of Barcodes
In 1948, a local food shop owner Philadelphia (Pennsylvania) requested Bernard Silver, a research student to devise a method of automatically reading product information during checkout. Bernard Silver joined together with fellow research student Joseph Woodland to work on a solution. After four years of hard work, Woodland and Silver developed a method of “article classification through the medium of identifying patterns” and got it patented on the 7 October 1952.
Thus began the system of barcodes. The first product to have a bar code was Wrigley’s Gum. Bar codes were first used commercially in 1966, but it was soon realized that there would have to be a common standard all over the world to derive maximum benefit.
The Universal Product Code (UPC) was the first bar code symbology to be widely adopted. This was on 3 April 1973. Foreign interest in UPC led to the adoption of the EAN (European Article Numbering) code format, similar to UPC, in December 1976.
Currently, the United States and Canada use UPC bar codes as their standard for retail labeling, whereas the rest of the world uses EAN. Numerous other methods of bar-coding have evolved ever since. Originally barcodes were, stored data in the widths and spacing of printed parallel lines, but nowadays they also come in patterns of dots, concentric circles, and hidden in images. Also today we have numeric-only barcodes, alphanumeric barcodes and 2-Dimensional barcodes.
An Example
Consider a barcode found on a loaf of bread which contains a 12-digit product number. When this number is scanned by the cashier, it’s transmitted to the store’s computer which finds the record associated with that item number in its database. The matching item record contains a description of the product, vendor name, price, quantity-on-hand, etc. The computer instantly does a “price lookup” and displays the price on the cash register (it also subtracts the quantity purchased from the quantity-on-hand.) This entire transaction is done instantly; think of how long it would take the cashier to key in a 12-digit number for every item you wanted to buy!
Barcodes are thus a time saving, cost effective and accurate means of handling and checking large numbers of consumer goods.

Apes And Human


The Relationship between Apes and Humans


Since scientists developed the ability to decode the genome and compare the genetic makeup of species, some people have been stunned to learn that about 98.5% of the genes in people and chimpanzees are identical. This finding means chimps are the closest living biological relatives to humans, but it does not mean that humans evolved from chimps. What it does indicate is that humans share a common ancestor with modern African apes (i.e., gorillas and chimpanzees), making us very, very distant cousins. We are therefore related to these other living primates, but we did not descend from them.
Modern humans differ from apes in many significant ways. Human brains are larger and more complex; people have elaborate forms of communication and culture; and people habitually walk upright, can manipulate very small objects, and can speak.

Amazing Language Facts


  1. Amazing Language Facts




There are more than 2,700 languages in the world. In addition, there are more than 7,000 dialects.
A dialect is a regional variety of a language that has a different pronunciation, vocabulary, or meaning.
The most difficult language to learn is Basque, which is spoken in northwestern Spain and southwestern France. It is not related to any other language in the world. It has an extremely complicated word structure and vocabulary.
All pilots on international flights identify themselves in English.
Somalia is the only African country in which the entire population speaks the same language, Somali.
The language in which a government conducts business is the official language of that country.
More than 1,000 different languages are spoken on the continent of Africa.
Many languages in Africa include a “click” sound that is pronounced at the same time as other sounds. You must learn these languages in childhood to do it properly.

All About Lotus



All about Lotus
A symbol of purity, fertility, eternity and the divine seat of the goddess Lakshmi, the lotus is also the National Flower of India. Here’s why this flower is so pure.
In India, the lotus is considered as a sacred flower and a lot of folklore and religious mythology is woven around it. It is also the national flower of India.
Religious and social symbolism
The lotus stands tall, clean and beautiful despite its murky surroundings. Rich in meaning and metaphor; it is considered as the foremost symbol of purity, beauty, wealth and fertility. It is also symbolic of youth and feminine beauty.
Laxmi, the goddess of wealth, and several other deities, sit on huge lotus flowers. Many gods and goddesses are also depicted holding a lotus in one of their (many) hands!
Hinduism adjures human beings to be like the lotus–to maintain the purity of the mind and body while floating on the muddy waters of sins and desires.
The seeds of the lotus have been found to be viable for germination even after thousands of years. Hence it is a symbol of a strong vital force that can withstand extremely adverse conditions.
Buddhism also attaches a lot of importance to the lotus.
The popular ‘padmasana’ in yoga means the ‘lotus position’.
Science
Moving to science, the botanical name of the lotus is Nilumbo Nucifera. Here, it is just another flower. But its peculiar properties have awed scientists. Research shows that the lotus is indeed pure -even from the scientific point of view.
You must have seen those large round lotus leaves. If you can get one them, try splashing lots of water on them. You will find that all the water rolls off the leaf. Then, if you touch the leaf it will still be dry. What is it that makes it water repellent?
Scientific research shows that the leaves of all aquatic plants secrete wax crystals. Thus the leaves are in a sense, coated with a layer of wax which repels water. This prevents the leaves from getting drenched in the water around them. Interestingly, these wax crystals also help the leaves to retain the required amount of water within them.
Further studies by scientists have led to the discovery of something more interesting. It has been called the “lotus effect”. According to this, the lotus has an amazing ability to clean itself. It can easily wash off any dirt or microorganisms such as bacteria that try to settle on it.
To understand how they do it, we must take a deeper look into the structure of the lotus leaves. Contrary to popular belief, lotus leaves are not smooth. When the leaf cells are examined under a powerful microscope, they are seen to have a bumpy surface. This means that the surface of the leaf is actually rough. These rough surfaces were found to be spotlessly clean. They did not require to be cleaned even for viewing under the microscope.
Where does the dirt go?
The dirt particles form its surroundings lodge themselves on the tip of the wax crystals on the leaf. Also, because of the roughness they cannot hold on very tightly to the surface.
Next, when water comes in contact with the surface, it forms droplets which slide off immediately. Since the dirt particles rest loosely on the miniature bumps, they stick more strongly to the water droplets than to the leaf surfaces. Therefore the water droplets carry away the dirt particles as they run off. In this way they the lotus manages to wash itself without any effort.
Had the surface been smooth, the dirt particles would have been pushed from one part of the leaf to the other. Also on a flat surface they would find a greater contact area and hence would rest more firmly.
Even if a few of the microorganisms remain on the leaf, they do not get water for survival and eventually die. Thus the lotus is able to purify itself.

Whales!



Whales are the gigantic ocean mammals that are enormous with powerful tails. The interesting thing about these large sea mammals is that they are virtually harmless and are highly social animals with complex languages and intelligence, just the opposite as giant animals or whales are shown in movies. They are called gentle giants because of their nature. Blue whales are the biggest of all. They feed on krill, a tiny shrimp that lives in tremendously large schools in almost every ocean of the world. A big blue whale can eat over a thousand krill at one time just by swallowing them with a tongue that weights as much as an elephant. From this we can imagine that just everything about a whale is simply big. Apart from these the whales also like to eat Small fish and plankton. 8,000 lbs/3600kg of fresh seafood a day is what a whale’s diet is. The most amazing thing about blue whales is their sound which is louder. Scientists have measured the low-frequency (deep rumbling) sounds they make when they communicate with each other by using a decibel meter. Some of their vocalizations have been recorded as loud as 188 decibels and can be heard as far as 530 mi/848km away. So, when you will go on a voyage, just keep your eyes open to get a look of this innocent mammal.

Jellyfish



While strolling on the sea beach sometimes we can see a kind of creature that looks like something transparent. They are the jelly fish that might have been brought on shore by the huge waves of the sea. Kids are often very curious to know more about these sea creatures mostly because the kids are attracted for the looks that a jelly fish bears. The striking information is that they are one of the oldest species and they are believed to have appeared in the oceans about 650 million years ago, even before the dinosaurs. They are still found in large numbers in the sea in various sizes and shapes. Though it is hard to believe but the fact is that their bodies are made up of 95% water; they have no bones or cartilage, no heart or blood, and no brain. Isn’t it amazing? They are the most primitive life forms on earth. The Arctic Lion’s Mane, like most jellies, is a killer – it kills and eats other living creatures. Fish, plankton, and even other jellies are its main foods. A Jellyfish has almost invisible tentacles which are loaded with millions of nematocysts which it uses for injecting paralyzing venom into the victim and then consumes its prey.

How Do Animals See Color?

The world is full of colors. Do you know how animals see color? Different types of animals see colors in different ways. Some animals have very poor color vision, for example dogs, cats, mice, rats and rabbits. In fact, they see mostly greys and some blues and yellows. The most common mistake that we make is that we think that a red cape makes a bull angry. But the real thing is that bulls are color blind. They charge the red cape just because it is moving and not because it is red. Some animals do have good color vision. Monkeys, ground squirrels, birds, insects, and many fish can see a fairly good range of color. In some cases it’s not as good as what we humans see – but it’s much better than cats and dogs. Scientists say that good color vision in some animals helps them in finding food on the land or in the water. Good color vision in some of the land animals helps them to differentiate between ripe red fruit and unripe green fruit. Colors can also make animals more attractive to each other when they mate. The ability to see colors also helps animals identify other animals that may attack them. Bees and butterflies can see colors that we can’t see. Their range of color vision extends into the ultraviolet which guide the insects deep into the flower.

Polar Bears



There are different types of animals that can only survive in the coolest places on the earth. Heard of polar bears? Arctic sea ice, water, islands, and continental coastlines around the Arctic Circle are dwelling place to these gigantic carnivores. The temperatures where these bears live ranges from an average -29°F/-34°C in winter and 32°F/0°C in summer. The coldest area in winter is northeastern Siberia, where the temperature has been recorded as low as -92°F/-69°C is not at all a place suitable for us but it is absolutely fine with these polar bears whose body is covered naturally with an extremely dense fur coat. Do you know what the favourite food of all these polar bears is? Seals. The polar bears spend a huge time moving great distances in search of their food. They can cover 20000 to 135000 square miles. They eat a lot in order to survive and develop a thick layer of fat which in turn helps them to keep themselves warm in such a chilly temperature. Another interesting fact about these guys is that they are excellent swimmers. They can swim for several hours and can hold their breath for about two minutes when they dive underwater. Male polar bears are called boars and female polar bears are called sows and their babies are called cubs.

Kids Love Penguins





Hey kids, do you remember about the penguins in the Hollywood blockbuster film, “Happy Feet”? You must be eager to know more about penguins, right? Here are some general facts about penguins that you will care to know. Penguins are sea birds that cannot fly. They mostly dwell in the Southern Hemisphere. In all, there are 18 species of penguins, found in South Australia, New Zealand, and off the coasts of Peru, Chile, and South Africa. Some species live as far north as the equatorial Galapagos Islands, but they are primarily cold-weather birds. There are seven species of Antarctic penguins: the Adelie, Gentoo, Macaroni, Chinstrap, Rockhopper, King, and Emperor. The Adelie and the Emperor are the two true Antarctic species. Penguins spend their life in the sea. Some species spend as much as 75% of their lives in the water though they lay their eggs and raise their chicks on land. Heavy, solid bones act like a diver’s weight belt, allowing them to stay underwater. Their wings, shaped like flippers, help them “fly” underwater at speeds up to 15 mph. A streamlined body, paddle-like feet, insulating blubber, and watertight feathers all add to their efficiency and comfort underwater. They also have a remarkable deep-diving ability. They are well suited for Antartica.

CHRISTMAS TREES



CHRISTMAS TREES
The tradition of the Christmas tree dates back to the middle ages and caught on in the United States in the 1800′s. Today, approximately 15,000 US growers tend one million acres of Christmas tree farmland.
The price for trees averages $5.65 per foot. Among some of top selling trees in the US are: Balsam fir, Douglas fir, Eastern white pine, Fraser fir, Noble fir, Scotch pine and Virginia pine. In 1996, 37 million Christmas trees were sold in the US alone.

Chocolate Facts!



Chocolates are always favourite with kids. Kids can indulge themselves in chocolates anytime. Now here are some interesting facts for the kids about chocolates. Chocolate is actually obtained from the cacao tree, which is 12 meters high and bears small pinkish flowers that grow into pods, and each pod produces 20 to 40 beans. A tree is likely to bear 60 to 70 such pods after its fourth year. After harvesting, the pod is split and the beans are allowed to ferment for several days. Then the beans are dried, cleaned, roasted and ground to yield a paste called chocolate liquor. After further processing and blending, this paste is made into a variety of chocolate products. This is how chocolates are made out of the chocolate beans. Another striking fact is the name of the cocoa tree. The botanical name for this tree from which chocolate is obtained is Theobroma Cacao which means “Food of the Gods” and the name seems to be appropriate. Kids will definitely love to know some more attention-grabbing facts about chocolates. Chocolate has 500 flavours in it. Cocoa beans were used as currency by the Aztecs and the Mayans. It is also an interesting fact that Napoleon took chocolate along with him during his military campaigns and had them whenever he required more energy

Footwear Facts


Footwear Facts
Sandals originated in warm climates where the soles of the feet needed protection but the top of the foot needed to be cool.
4,000 years ago the first shoes were made of a single piece of rawhide that enveloped the foot for both warmth and protection.
In Europe pointed toes on shoes were fashionable from the eleventh to the fifteenth centuries.
In the Middle East heels were added to shoes to lift the foot from the burning sand.
In Europe in the sixteenth and seventeenth centuries heels on shoes were always colored red.
Shoes all over the world were identical until the nineteenth century, when left- and right-footed shoes were first made in Philadelphia.
In Europe it wasn’t until the eighteenth century that women’s shoes were different from men’s.
Six-inch-high heels were worn by the upper classes in seventeenth-century Europe. Two servants, one on either side, were needed to hold up the person wearing the high heels.
Sneakers were first made in America in 1916. They were originally called keds.
Boots were first worn in cold, mountainous regions and hot, sandy deserts where horse-riding communities lived. Heels on boots kept feet secure in the stirrups.
The first lady’s boot was designed for Queen Victoria in 1840.

Why do a cat’s eyes glow in the dark?
The cat’s eyes are adapted for seeing in the dark. During the day, the pupils contract, but at night they open wide letting in every bit of light possible. The back of the eyes is coated with polished silvery pigments called Eumelanin and Phaeomelanin, which reflects every bit of light that falls on the eye. That is why cat’s eyes glow in the dark.
How do parrots talk?
Parrots do not talk; they only imitate sounds that human beings make. They can’t express themselves and are definitely not sharing any thoughts, they ‘talk’ simply because they enjoy imitating sounds. Parrots do not learn human speech easily.

* At the radio station, the announcer speaks into a microphone. The microphone changes the sound of his voice into an electrical signal. This signal is weak and can't travel very far, so it's sent to a transmitter. The transmitter mixes the signal with some strong radio signals called carrier waves. These waves are then sent out through a special antenna at the speed of light! They reach the antenna of your radio. Your antenna "catches" the signal, and the radio's amplifier strengthens the signal and sends it to the speakers. The speakers vibrate, and your ears pick up the vibrations and your brain translates them into the voice of the radio announcer back at the station. When you consider all the places the announcer's voice travels.

Giraffe

The giraffe (Giraffa camelopardalis) is the tallest living terrestrial animal species. On average, it is about 4.3 metres to 5.2 metres tall. Giraffes belong to the family giraffidae. It is believed that the giraffids evolved from a 3 metres tall antelope-like mammal that roamed Europe and Asia some 30–50 million years ago.Fully grown male giraffes weigh between 800 and 1,930 kilograms and fully grown female giraffes weigh between 550 and 1,180 kilograms. As the forelegs of giraffes are about 10% longer than their hind legs, giraffes can reach a sprint speed of up to 60 km/h. A giraffe's heart measures about 60 cm long and weighs upto 10 kg. It generates about double the amount of normal blood pressure generated by an average land mammal. A giraffe can eat about 29 kg of leaves and twigs daily. On average, it sleeps for about 1.9 hours per day. The neck of a giraffe is over 2 metres long. It accounts for nearly half of the animal's vertical height.
