During what war was the hydrogen bomb invented?

It wasn't invented during a time of war. It was invented well after the end of WW II.

Richard Lawrence Garwin, American physicist, produced a design in 1952 at IBM Watson Laboratory at Columbia University. This was during the period that the US was involved in the Korean War (1950-1953).

Why do scientist accept the big bang theory?

The BB model makes predictions about what we should see from our Earth. Other models predict that these things should NOT be seen, or (at best) fail to explain why they would be there.

As the predictions made by the BB (cosmic microwave background radiation, ratio of hydrogen to helium to deuterium, age of oldest stars, no old galaxies far from our Earth) are all confirmed as being true, honest scientists have little choice but to accept the BB as the correct model for our Universe.

What was the IQ of Louis Pasteur?

Intelligence testing began in France by Dr. Alfred Binet in 1904. Pasteur died in 1895. The IQ test had not been yet stablished so we can only pressume. By his work, I would rate him between 177 and 185. Some of my fellows argue that he could be around 155 and 160 since he did not reach topics taken by Albert Einstein. I rest my case in the fact that this other topics were not his type of work to choose from. In fact he could be concidered the Einstein of microbiology and chemistry for his discoveries and work.

Did Guglielmo Marconi have two wives?

Marconi married Beatrice O'Brien in 1905. They had three daughters and a son. They divorced in 1924 and the marriage was annulled in 1925.

Marconi married Maria Cristina Bezzi-Scali in 1927.

Did the Roman Catholic Church support Galileo's theory that the earth moves around the sun?

It's a rather more complicated answer that "yes" or "no." In fact, most of the intellectuals in the Church in Galileo's time thought the heliocentric version of the Solar System was the correct one, BUT -- and here's the catch -- the Church had managed to get itself associated with Aristotlean thought, which, with most of the Ancient Greek cosmologies, except that of Aristarchos of Samos, accepted the geocentric version. In short, the Church was afraid that putting out the Copernican view (i.e., heliocentrism) would so upset the common folk that those who lose their respect for the Church. It was all rather like one of those dramas in which the intrepid investigator uncovers some secret but the powers that be (CEOs, government officials, hospital administrators, etc.) tell him to cover it back up because to reveal it publically would "cause panic."

What is so painfully ironic to the Galileo Affair is that nothing in Scripture or Church teaching really demands the Earth be the center of the Universe. There are, of course, references in the Old Testament that sort of make the assumption that the Earth is the most important place (other that heaven, of course) but these are easily seen as comments of perspective, which is to say, they were all made by people who happened to be living on the Earth. Even with our modern and presumably correct understanding of celestial mechanics, we still say things like "sunrise" and "sunset" instead of "Earthturn."

What is commonly presented as a conflict between Science and Religion would be better described as a conflict between Control and Threats to Control.

Who are some famous scientists who contributed in the field of electricity?

Andre Ampere

Andre Marie Ampere was the first to explain the electro-dynamic theory. A permanent memorial to Ampere is the use of his name for the unit of electric current.

George Ohm

George Simon Ohm published, "The galvanic Circuit Investigated Mathematically". His theories were coldly received by German scientists. His name has been given to the unit of electrical resistance.

James Watt

James Watt invented the steam condensing engine. His improvements to steam engines were patented over a period of 15 years, starting in 1769 and his name was given to the electric unit of power, the Watt.

Thomas Edison

A really practical DC (Direct Current) generator was built by Thomas Edison. Edison's many inventions included the phonograph and an improved printing telegraph.

Joseph Swan

Joseph Swan nvented the incandescent filament lamp and within twelve months.

Swan and Edison later set up a joint company to produce the first practical filament lamp. Prior to this, electric lighting had been my crude arc lamps.

William Thomson (Lord Kelvin)

He made important contributions to many areas of Physics including electricity, magnetism and thermodynamics. He was created Lord Kelvin for his work on the first transatlantic cable.

Which microbe did Louis Pasteur say causes fermentation?

Louis Pasteur discovered that fermentation was caused by a microbe and that the wine went off if other sorts of microbe got into it at the same time.

Why might scientist prefer using metric unit rather than feet or inches?

Mainly to use an accepted standard (scientists all over the world use the same units). Also, it is easier to do calculations in metric units.

Who is john j loud?

John J Loud patented the ballpoint pen on 30th October 1888

What is the Bohr atom model of Sulfur?

A Bohr Atom Model consists of a CORE of 16 Protons and 16 Neutrons (32 total)

AND 16 total Electrons in the Energy Levels, the inner-most level has 2, the second level has 8, and the third level has 6. It would look kinda like Saturn, a core with "rings" and the "rings" would have "balls" on them that would represent the Electrons. Good Luck!

That is the way to do it... but if you want a visual go to the related link below.

How do you know that Leonardo da Vinci was interested in science and engineering?

A noble might be interested in Leonardo da Vinci's engineering ability for many reasons. It is most likely, however, that in da Vinci's own day, a contemporary noble might be interested for the sake of gaining an advantage on the battlefield, as da Vinci proved capable of devising both fantastic and practically possible war-machines both large and small.
