Neil Alden Armstrong (August 5, 1930 – August 25, 2012) was an American astronaut, test pilot, aerospace engineer, university professor and United States Naval Aviator. He was the first person to walk on the Moon. Before becoming an astronaut, Armstrong was a United States Navy officer and had served in the Korean War. After the war, he served as a test pilot at the National Advisory Committee for Aeronautics High-Speed Flight Station, now known as the Dryden Flight Research Center, where he logged over 900 flights. He graduated from Purdue University and the University of Southern California.
A participant in the U.S. Air Force’s Man In Space Soonest and X-20 Dyna-Soar human spaceflight programs, Armstrong joined the NASA Astronaut Corps in 1962. His first spaceflight was the NASA Gemini 8 mission in 1966, for which he was the command pilot, becoming one of the first U.S. civilians in space.[1] On this mission, he performed the first manned docking of two spacecraft with pilot David Scott.
Armstrong’s second and last spaceflight was as mission commander of the Apollo 11 moon landing in July 1969. On this mission, Armstrong and Buzz Aldrin descended to the lunar surface and spent 2½ hours exploring, while Michael Collins remained in orbit in the Command Module. Armstrong was awarded the Presidential Medal of Freedom by President Richard Nixon along with Collins and Aldrin, the Congressional Space Medal of Honor by President Jimmy Carter in 1978, and the Congressional Gold Medal in 2009.
On August 25, 2012, Armstrong died in Cincinnati, Ohio,[2] at the age of 82 due to complications from blocked coronary arteries.

Avionics Related to the the electronic instrumentation and control equipment used in airplanes and space vehicles.
Avionics (ā’vēŏn‘ĭks), electronic instruments used in air or space flight; also the design and production of such instruments. Early planes had few instruments, but as aviation and aircraft became more complex, so did instrumentation. Most of the new technology was electronic; hence, the expression “aviation electronics” arose and was later shortened to “avionics.” After World War II, the increasing sophistication of military avionics helped spawn a proliferation of electronic applications to commercial and private aviation. Avionics includes numerous types of devices, including those used for navigation control instruments that aid in steering and controlling the craft; and performance indicators, such as altimeters and velocity gauges.

Archimedes’ Principle: It states that a body, when immersed in a liquid, experiences an upward thrust equal to the weight of the liquid displaced by it.
Avogadro’s Hypothesis: It is a modification of Berzelius’ hypothesis. It states that equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules. Avogadro’s law is applicable only to gases.
Boyle’s Law: states that the volume of certain gas is inversely proportional to the pressure at a constant temperature. In other words the product of pressure and volume remains constant provided the temperature is kept constant i.e., P x V = a constant if T remains the same.
Charles’s Law: It states that at constant pressure all gases expand by 1/273 of their volume at 0°C for a rise in temperature of 1°C i.e., the volume of a given mass of gas at constant pressure is directly proportional to the absolute temperature.
Dulong and Petit’s Law: states that the product of atomic weight and specific heat of solid elements is nearly equal to 6.4 i.e., At wt. x sp. heat = 6.4 approx.
Gay-Lussac’s Law of combining volumes: Gases react together in volumes which bear simple whole number ratios to one another and also to the volumes of the products, if gaseous—all the volumes being measured under similar conditions of temperature and pressure.
Graham’s Law of Diffusion: states that the rates of diffusion of gases are inversely proportional to the square roots of their densities under similar conditions of temperature and pressure.
Kepler’s Law: According to this law, a line drawn from the sun to a planet, moving around it, sweeps over a fixed area in a given interval of time.
Law of definite proportions: A chemical compound is always found to be made up of the same elements combined together in the same ratio by weight.
Law of Floatation: for a body to float, the following conditions must be fulfilled: (1) The weight of the body should be equal to the weight of the water displaced. (2) The centre of gravity of the body and that of the liquid displaced should be in the same straight line.
Lenz’s Law: When there is change in the magnetic flux linked with a circuit, the electric current induced in the circuit will have a magnetic field opposing the change producing it.
Newton’s Law of Universal Gravitation: states that “Every portion of matter attracts or tends to approach every other portion of matter in the universe with a force proportional to the masses and inversely as the square of the distance.”
Newton’s First Law of Motion: “A body continues in its state of rest or of uniform motion in a straight line unless compelled by an external force to change that state.”
Newton’s Second Law of Motion: “The rate of change of momentum is proportional to the impressed force and takes place in the direction of the force.”
Newton’s Third Law of Motion: “To every action, there is an equal and opposite reaction.”
Newton’s Law of Cooling: states that the rate of loss of heat of a hot body is directly proportional to the difference of temperature between the body and the surroundings and is independent of the nature of the body.
Ohm’s Law: states that the ratio of the potential difference between the ends of a conductor and the current flowing in the conductor is constant, e.g., for a potential difference of E volts and a current I amperes, the resistance R, in ohms is equal to E/I.
Principle of conservation of energy: It states that, in any system, energy cannot be created or destroyed; the sum of mass and energy remains constant.
Snell’s Law: It states that the ratio of the sine of angle of incidence to the sine of the angle of refraction remains constant for any two given media.
Specific heat of substance: The quantity of heat required to raise the temperature of 1 gram. of a substance through 1°C.

Nano is actually a SI prefix denoting 0.000 000 001, and for instance one nano-meter means one billionth of a meter. Obviously nano is referring to the fields dealing with such small scales (roughly 1–100 nm). It should be emphasized that ‘nano’ as a field of study, deals with size; and nano scale of e.g. time, concentration, etc are not normally considered as the nano discipline (the reason is given below).
Nanotechnology describes the creation and utilisation of functional materials, devices and systems with novel functions and properties that are based either on geometrical size or on material-specific peculiarities of nano-structures. Purely geometrically the prefix “nano” (greek: dwarf) describes a scale 1000 times smaller than that of present elements of the micrometer-sphere (1nm corresponds to the millionth part of a mm). This scale has become accessible both by application of new physical instruments and procedures and by further diminution of present microsystems. Also structures of animated and non-animated nature were used as models for self-organising matter. Only if the mastery of this atomic and molecular dimension succeeds, the prerequisites for the optimisation of product properties within socioeconomic areas such as energy engineering, environmental technology as well as in information technology, health and ageing can be developed.

What are Vyomnauts?
India’s First space mission is scheduled for 2015. In this mission three-person vehicle will initially carry two astronauts into 275-kilometre low-Earth orbit.
The ISRO is in process of choosing four astronauts from a pool of 200 fighter pilots. the media has coined a new term for Indian astronauts – Vyomnauts.
Vyoma is space. The correct sanskrit term is Vyomagami yet
