Who is the World's youngest king ?

1. England .
2. Japan .
3. Bhutan
4. Nepal

Ans : 3





At 31, King Jigme Khesar, known as the "Asian Elvis," because of his hair style, is apparently the youngest king in the world. He went to college in the Boston area and is a huge Celtics fan.
Khesar was coronated in 2008 when his father, a man with four wives, all sisters, decided to step down. The new king announced in May that he'd chosen a wife, a 21-year-old student named Jetsun Pema, the daughter of an airline pilot, who likes painting and sports.

Who is the Founder of google ?

1. Morgen Stanly and Credit Suisse.
2. Perkins Caufield and Byers.
3. Larry Page and Sergey Brain
4. Vinod Khosla and Georage Bell


Ans : 3




Google began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford University in California.


Sergey Mikhaylovich Brin (Russian:  born August 21, 1973) is an American computer scientist and Internet entrepreneur who, with Larry Page, co-founded Google, one of the most profitable Internet companies. As of 2012, his personal wealth is estimated to be $18.7 billion.
Brin immigrated to the United States from the Soviet Union at the age of six. He earned his undergraduate degree at the University of Maryland, following in his father's and grandfather's footsteps by studying mathematics, as well as computer science. After graduation, he moved to Stanford University to acquire a Ph.D in computer science. There he met Larry Page, with whom he later became friends. They crammed their dormitory room with inexpensive computers and applied Brin's data mining system to build a superior search engine. The program became popular at Stanford and they suspended their PhD studies to start up Google in a rented garage.
The Economist magazine referred to Brin as an "Enlightenment Man", and someone who believes that "knowledge is always good, and certainly always better than ignorance", a philosophy that is summed up by Google’s motto of making all the world’s information "universally accessible and useful" and "Don't be evil".

Who invented Bluetooth Technology ?

1. Jaap Haartsen .
2. Seven Mattisson.
3. Ericsson.
4. King Harald Blatan of Denmark


Ans :4



The name Bluetooth comes from King Harald Blatan (Bluetooth) of Denmark, who in the 10th century, began to Christianize the country. Ericsson, a Scandinavian company, was the first to develop this specification. See Bluejacking, Bluesnarfing, Cabir, PAN, wireless adapter and wireless LAN.

The name Bluetooth is derived from the cognomen of a 10th century king of Denmark, Harald Bluetooth. According to the inventors of the Bluetooth technology, Harald engaged in diplomacy which led warring parties to negotiate with each other, making Bluetooth a fitting name for their technology, which allows different devices to talk to each other
 Created by telecoms vendor Ericsson in 1994.

Who invented Atom Bomb ?

1 .Albert Einstein did create the formula E=mc2..
2. Robert Oppenheimer
3. Danish Scientist Niels Bohr
4. Edward Teller

Ans: 2


Robert Oppenheimer headed the Manhattan Project where a lot of scientists contributed.

During World War II, the United States, with the assistance (collaboration) of physicists, mathematicians, and engineers from the U.S., Britain, Canada and Germany (former Nazi physicists), completed the Manhattan Project to produce the first atomic bomb.
(The project started as the "Manhattan District Engineers" and only became "The Manhattan Project" some time later).

There was some early speculation about the possibility of what could be done if a nuclear chain reaction was unleashed in a way that would allow it to build without control. For a roll call, consider that Robert Oppenheimer was the head of "science" for the Manhattan Project, and (in alphabetical order) Felix Block, David Bohm, Niels Bohr, Enrico Fermi, James Franck, Otto Frisch, Klaus Fuchs, Rudolf Peierls, Emilio Segre, Leo Szilard, Edward Teller and Eugene Wigner all played crucial roles in getting the weapon designed and built.

The physicist Albert Einstein did not participate directly in the invention of the atomic bomb-but was instrumental in facilitating its development. His Special Theory of Relativity emphasized that a large amount of energy could be released from a small amount of matter. This was expressed by the equation E=mc2 (energy = mass times the speed of light squared). The atomic bomb would clearly illustrate this principle.

The first demonstration of "the gadget" (the code name for the first atomic bomb) was at Trinity site in Alamogordo, New Mexico, and it proved that the weapon would detonate and that the chain would build as predicted. The second and third demonstrations were conducted in Japan, which brought a quick end to the Second World War. Just up to and during World War 2, Germany was also working to develop atomic weapons, but was hampered by many technical and political problems (including sabotage and Allied bombings) which prevented their successfully completing their work. This left the U.S. as the only nation to ever unleash nuclear weapons in an attack.

Who Invented Zero ?

1. Aarybhatt.
2. Samundra gupt.
3  Brahamagupta.
4  Bhaskar.

Ans: 3

The credit for this goes to Indian mathematicians and the number zero first appears in a book about ‘arithmetic’ written by an Indian mathematician ‘Brahamagupta’. Zero signifies ‘nothing’ and the current definition calls it an ‘additive identity’.
Mathematically; x + 0 = x, i.e. 0 is a number which, when added to a number yields the same number.
When we go deeper, it becomes clearer that the things are much more complex. It wasn’t that somebody suddenly came up with the idea of the zero and the mathematicians throughout the world accepted it. Around 500 AD, Aryabhata, an Indian mathematician, devised a numbers system and the symbol he used for the number zero was also the number used to represent an unknown element (x). This system was confusing but the improvements continued and by 876 AD, the concept of zero was mostly understood and the symbol for it was ascertained.
The Indian mathematicians Bhaskara, Mahavira and Brahamagupta worked on this new number and they tried to explain its properties. Some were true and some were not. For example, Bhaskara correctly that stated 0² = 0 and 0^1/2 = 0 but he was wrong to have supposed that n/0 = Infinity. If n/0 = Infinity were to be true there would arise results which don’t make sense. One of them was 1 = 2 = 3 …….
The reason of this was that the Indian mathematicians could not conclude that no number could be divided by zero. The Maya people in present day Mexico knew and understood the concept of zero but because they were so much disconnected with the rest of the world civilizations, it had little impact on the rest of the world.
