Smallest Girl on this Earth
Jyoti Amge is the smalest girl on this earth. Now she is 14 years of old weighing only 5 Kg. She has a form of dwarfism called achondroplasia and won't grow any taller than her current height. Due to her size, Jyoti has to have clothes and jewellery made for her. She sleeps in a tiny bed and uses special plates and cutlery to eat, as normal-sized utensils are too big. Despite this, she goes to a regular school in Nagpur, central India, where she has her own small desk and chair, and her classmates treat her like any other student ![]()

Amazing Facts About the Human Body The nasal bones are especially structured so that the air inhaled can go to the lungs only after circulating several times in the nose and thus warming up. The thighbone can bear a weight weighing a ton when perpendicular. When an athlete pole-vaults and he lands on the ground, every square centimeter of his pelvis is exposed to a pressure of 1,400 kilograms. Even for a faint smile, 17 muscles have to work together at the same time. A liver cell is specialized enough to perform more than 500 operations at a time. The heart connects the 100 trillions cells in the human body one by one. The heart beats approximately 100,000 times a day. The human body has resistance to approximately 600 rads of radiation, whereas the tolerance of scorpions rises as high as 40-150 thousand rads. A normal human body has about 5 billion capillaries whose total length, if stretched out, is about 950 kilometers. Special secretion in the nasal mucous retains and sweeps out about 80-90of the micro-organisms that gain entry to the respiratory system directly or through dust. One B cell can pump out more than 10 million antibody molecules an hour. Our heart pumps about 43,000 liters of blood per day. The simplest cells have roughly 2,000 different types of proteins. If the information in DNA were put in the form of a book, these books put on top of each other would reach 70 meters high. The DNA of a single cell contains the design of 206 bones, 600 muscles, a network of 10,000 auditory muscles, a network of 2 million optic nerves, 100 billion nerve cells, and 100 trillion cells in the body. The probability of the amino acid sequence of a protein made up of 500 amino acids being in the correct order is 1 in 10950. A brain cell is in constant interaction with others numbering up to 10,000. This communication network is far more complex than all the switchboards in the world. The nucleus of each of the trillions of cells making up the human body includes a data bank big enough to fill a 900-volume encyclopedia. The human eye works by some 40 different parts functioning together. The retinal membrane at the back of the eye is made up of 11 different layers. Each red cell can carry 300 million hemoglobin molecules. When we inhale, oxygen floods into about 300 million tiny chambers in our lungs. If water were only slightly more viscous, it would be impossible for blood to be transported through the body's capillary system. Water makes up about 70 percent of the human body. Immune system elements that the baby needs, such as antibodies or defense cells, are given to the baby ready-made in the mother�s milk. There is 5 liters of blood in the body of a human weighing 60 kilograms. Due to their incredible flexibility, red cells, with a diameter of about 7.5 micrometers, can squeeze through capillaries which are normally four to five micrometers in diameter. A single brain can process work equivalent to that of 4.5 million transistors on a modern microprocessor. The human kidneys filter about 140 liters of blood every day through one million small filtering units. The lifespan of a red blood cell is about 120 days.

Making of Eiffel Tower
![]() The Eiffel Tower is an iron tower built on the Champ de Mars beside the River Seine in Paris. The tower has become a global icon of France and is one of the most recognizable structures in the world. The Parisian landmark is the tallest structure in Paris and one of the most recognized structures in the world and is named after its designer, engineer Gustave Eiffel. ![]() The structure was built between 1887 and 1889 as the entrance arch for the Exposition Universelle, a World's Fair marking the centennial celebration of the French Revolution. The structure of the Eiffel Tower weighs 7,300 tons. Depending on the ambient temperature the top of the tower may shift away from the sun by up to 18 cm (7 in) due to thermal expansion of the metal on the side facing the sun. The tower also sways 6-7 cm (2-3 in) in the wind. ![]() ![]() The tower was inaugurated on 31 March 1889, and opened on 6 May. Three hundred workers joined together 18,038 pieces of puddled iron (a very pure form of structural iron), using two and a half million rivets, in a structural design by Maurice Koechlin. The risk of accident was great, for unlike modern skyscrapers the tower is an open frame without any intermediate floors except the two platforms. Yet because Eiffel took safety precautions including use of movable stagings, guard-rails and screens, only one man died. |
