Yesterday And Today

  1. 1. <ul><li>The Wright brothers , Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912), were two Americans who are generally credited with inventing and building the world's first successful airplane and making the first controlled, powered and sustained heavier-than-air human flight, on December 17, 1903. </li></ul><ul><li>The Airbus A380 is a double deck, wide body, four-engine airliner manufactured by the European corporation Airbus; is the largest passenger airliner in the world. </li></ul>
  2. 2. <ul><li>The first automobile developed with a combustion engine was invented by Henry Ford. Henry Ford later founded the Ford Motor Company, which was known for its achievements in bringing America its first affordable car. </li></ul><ul><li>Inspired by the excellence Ford introduced King of the Road, Ford Mustang. 5.4-litre supercharged V-8 engine producing an estimated 540-horsepower makes it an excellent car. </li></ul>
  3. 3. <ul><li>In the 1870s, Alexander Graham Bell designed devices that could transmit speech electrically (the telephone). Bell's greatest success was achieved on March 10, 1876, marking the birth of telephone in the world. </li></ul><ul><li>The telephone technology became revolutionized with the introduction of Mobile phone. Current Mobile phones may support many services such as SMS, Email, Internet, Bluetooth, Camera, MMS, and many more </li></ul>
  4. 4. <ul><li>The pinhole camera is credited to Ibn al-Haytham for the first clear description and correct analysis of the device and for first describing how an image is formed in the eye. Pinhole camera consists of a light-tight box with a pinhole in the end. </li></ul><ul><li>Sony introduced the modern PMW-EX1 solid state camcorder . The transfer / read / write speeds of the new ExpressCard are much faster than others. PMW-EX1 records to cards that are available in 8, 16 and 32GB capacities and above making it the modern camcorder available. </li></ul>
  5. 5. <ul><li>There are many major milestones in the history of computers, starting with 1936, when Konrad Zuse built the first freely programmable computer. It was used to explore several ground breaking technologies in calculator development: floating point arithmetic, high capacity memory and modules or relays operating on the yes/no principle. </li></ul><ul><li>The fastest type of computers, supercomputers are used for highly calculation-intensive tasks such as problems involving quantum mechanical physical, weather forecasting, climate research, molecular modeling and petroleum exploration. </li></ul>
  6. 6. <ul><li>The earliest boats have been predicted to be logboats, or possibly boats made from hide or tree bark. The oldest boats to be found by archaeological excavation are logboats from around 7,000-9,000 years ago. </li></ul><ul><li>Royal Caribbean Voyager cruise is the largest and the most innovative cruise ship in the world , at 158,000 gross tons and holding 3,600 guests double-occupancy. It carries over 3800 passengers and almost 1200 crew and it weighs three times as much as the Titanic ship. </li></ul>
  7. 7. <ul><li> Television technology was actually first developed in the 19th century. In 1897, Ferdinand Braun invented the cathode ray tube. The first time the cathode ray tube was used to produce images was in 1907. The tube was an essential step in the invention of television. </li></ul><ul><li>A plasma display panel ( PDP ) is a type of flat panel display common to large TV displays (32&quot; inches or larger). Many tiny cells between two panels of glass hold a mixture of noble gases. The gas in the cells is electrically turned into a plasma which then excites phosphors to emit light and display pictures. </li></ul>
  8. 8. <ul><li>In 1440, German inventor Johannes Gutenberg invented a printing press process that transfers lettering or images by contact with various forms of inked surface onto paper or similar material fed into it in various ways. The device is used for printing many copies of a text on a paper. </li></ul><ul><li>The latest Gravure printing machine is capable of printing with the speed of 80 to 120m/minute, fully computerized. It is suitable for varied plastic rolling material with multiple color printing. </li></ul>
  9. 9. <ul><li>In 1879 Thomas Alva Edison invented a carbon filament that burned for forty hours. Edison placed his filament in an oxygenless bulb. He continued to improve his light bulb until it could last for 1200 hours. </li></ul><ul><li>Modern fluorescent bulbs produce light in a very different and more efficient way, that is why a 15-watt (w) fluorescent bulb generates the same amount of light as a 60w incandescent bulb. </li></ul>
  10. 10. <ul><li>The invention of the steam engine was critical to the invention of the modern railroad and trains. Richard Trevithick (1771-1833) built that vehicle, the first steam engine tramway locomotive. </li></ul><ul><li>The Bullet trains are the fast speed trains. The average speed of fastest scheduled train service in the world is 262km/h or 164mph. </li></ul>
