Science, Inventions & Technology Trivia

Michael Faraday discovered electromagnetic induction in 1831, which is the principle behind electric motors. His work showed that changing magnetic fields produce electric current, enabling motor operation.

Galileo Galilei was the first to use a telescope for astronomical observations in 1609, though he didn't invent the optical telescope itself. He significantly improved its design and made major discoveries.

John Ambrose Fleming invented the thermionic valve (also known as the vacuum tube or diode) in 1904. This invention was crucial for early radio technology and electronics, allowing for rectification of AC signals. It revolutionized communication technology.

C.V. Raman discovered the Raman Effect related to light scattering in crystals and molecules, which is fundamental to understanding crystal dynamics. This groundbreaking work in light scattering earned him the Nobel Prize in Physics in 1930.

Grote Reber built the first parabolic radio telescope in 1937, expanding astronomy beyond visible light. Roentgen discovered X-rays, Curie pioneered radioactivity research, and Galileo developed optical telescopes.

Alessandro Volta created the first true battery (Voltaic Pile) in 1800, producing steady electrical current. Edison developed light bulbs, Faraday discovered electromagnetic induction, and 'None' is incorrect.

Franklin invented bifocals, lightning rod, and odometer, but electrical induction was discovered by Michael Faraday through electromagnetic experiments. The question asks which is NOT Franklin's invention.

Thomas Edison invented the phonograph in 1877, the first device capable of recording and reproducing sound. Marconi developed radio, Grote Reber built radio telescopes, and Galileo was an astronomer.

Michael Faraday discovered diamagnetism in 1845 when he noticed that many materials exhibit a weak repulsion from a magnetic field. Fleming is known for his left/right-hand rules, and Edison for the lightbulb.

Microsoft was founded by Bill Gates and Paul Allen in 1975, not Gates and his father. Option C correctly identifies this as 'almost fact' with the proper correction.

Microsoft's stock options program during its rapid growth in the 1980s and 1990s created approximately 12,000 employee millionaires, making this one of the largest wealth-creation events in corporate history. This fact is widely documented in business literature about the tech boom.

Google's founders Larry Page and Sergey Brin originally named their search engine 'BackRub' in 1996 because it focused on backlinks. The project was later renamed Google in 1997, a play on the mathematical term 'googol.'

'Real solutions for real people' was not Microsoft's official corporate tagline. Microsoft's well-known taglines include 'Where do you want to go today?' and 'Your potential. Our passion.' The statement is therefore fiction.

Force is a vector quantity because it has both magnitude and direction, as described by Newton's laws. Scalar quantities like length, weight, and time have only magnitude without any directional component. Therefore, force is the correct answer as it is not a scalar.

Microsoft's revenue in fiscal year 2008 was approximately $60.4 billion, not $6 billion ($6000 million). The statement in the question is off by a factor of 10, making option D the correct response.

Boyle's Law states that for a fixed amount of gas at constant temperature, pressure and volume are inversely proportional (PV = constant). As pressure increases, volume decreases proportionally, and vice versa. This fundamental gas law was formulated by Robert Boyle in 1662.

Force is measured in Newtons in SI units. In the MLT (mass-length-time) system, Newton can be expressed as kg·m/s², which is mass times acceleration. Option D correctly shows Kgm/(s*s) which is equivalent to kg·m/s².

The Oxford English Dictionary did add 'Google' as a verb in 2006, meaning to search for information on the internet using the Google search engine. This marked a significant moment where a brand name became a commonly used verb.

In the CGS (centimeter-gram-second) system, the base unit of length is the centimeter. The SI system uses meters as the base unit, but CGS was developed earlier and uses centimeter as its fundamental length unit.
