OUR CLOSEST GALAXY ANDROMEDA..                 Andromeda  is the largest galaxy in the Local Group, which includes the Milky Way, the Triangulum Galaxy, and dozens of smaller dwarf and irregular galaxies. A recent estimate gave Andromeda 700 billion solar masses. Our Milky Way is only 80% the mass of Andromeda. IMAGE BY :  jpl.nasa.gov                  The Andromeda galaxy was first observed by Persian astronomers, thousands of years ago, and was later cataloged by Charles Messier in 1764. He classified it as M31. In 1912, astronomers calculated its speed to be 300 kilometers per second, moving towards the Sun. Edwin Hubble first calculated the distance to Andromeda, by detecting Cepheid variables in the galaxy. He measured that it was 450 kpc, or 2.5 million light-years away; well outside the Milky Way galaxy.                Rec...

IS TIME TRAVEL POSSIBLE ?? IN TO THE FUTURE...         We cannot avoid moving into our futures, but we  can  control the rate that we move through time. This is a consequence of another lesson from relativity: Not all clocks are the same.  The speed at which you move through space determines the speed at which you move through time. In the succinct phrase: Moving clocks run slow. IF you could build a big enough rocket (don't ask me how, that's an engineering problem) to provide a constant acceleration of 1g (9.8 meters per second per second; the same acceleration as provided by the Earth's gravity at its surface), you could reach the centre of the Milky Way galaxy — a healthy 20,000 light-years away — in just a couple decades of your personal time. You could stop for a few hours, have a picnic near Sagittarius A* (the black hole at the centre of the galaxy), and then hop back into your rocket and come back to Earth. By th...

HOW ATM WORKS WHAT IS ATM?           An ATM is simply a data terminal with two input and four output devices. Like any other data terminal, the ATM has to connect to, and communicate through, a host processor. The host processor is connected to an Internet Service Provider in that it is the gateway through which all the various ATM networks become available to the cardholder (the person wanting the cash).            Most host processors can support either leased line or dial-up machines. Leased line machines connect directly to the host processor through a four-wire, point-to-point, dedicated telephone line. Dial-up ATMs connect to the host processor through a normal phone line using a modem and a toll free number, or through an Internet Service Provider using a local access number via a modem.           Leased line ATMs are preferred for very high volume locations because of thei...

ALAN TURING        Turing was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation with the Turing machine, which can be considered a model of a general purpose computer. Turing is widely considered to be the father of theoretical computer science and artificial intelligence.           he was a British scientist and a pioneer in computer science. During World War II, he developed a machine that helped break the German Enigma code. He also laid the groundwork for modern computing and theorised about artificial intelligence.             Born on June 23, 1912, Turing was part of an upper-middle-class British family involved in colonial India. Science was a passion for young Turing, who often took part in primitive chemistry experiments. Before applying to...

WHAT IS ARDUINO ? Arduino  is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers  and  microcontroller  kits for building digital devices and interactive objects that can sense and control objects in the physical world.  "Uno" means one in Italian and is named to mark the upcoming release of Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduino, moving forward. The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform; for a comparison with previous versions, see the index of Arduino boards.
