Quiz Answer Key and Fun Facts
1. The Pythagorean theorem is a well-known principle in geometry. This theorem is named after a famous Greek philosopher and mathematician.

Answer: True

Pythagoras was a famous Greek philosopher and mathematician who lived in the fifth century BC. Pythagoras is known for his contributions to the fields of Mathematics, Metaphysics, Music and Ethics. His students and followers were known as Pythagoreans.

He is sometimes referred to as 'the father of numbers'. He is always remembered for the Pythagorean theorem of geometry. This famous theorem states that 'the square of the hypotenuse, in a right angled triangle is equal to the sum of the squares on the other two sides'.
2. A famous modern law is Murphy's law. Which of the following best describes what this law states?

Answer: If anything can go wrong, it will

Murphy's law is a famous law of modern times which is expressed in simple terms as 'If anything can go wrong, it will'. This law is attributed to Edward Murphy Jr, an aerospace engineer. While he was involved in the experiments at the Wright-Patterson Air Force base, he coined this law.

The actual statement of this law is 'If there's more than one way to do a job, and one of those ways will result in disaster, then somebody will do it that way.' 'Every action has an equal and opposite reaction' is the famous Third law of Newton. 'If it is good, they will probably stop making it' is known as Herblock's Law. Stein's law states that 'If something cannot go on forever, it will stop'.
3. Johannes Kepler has lent his name to a law. In which field is this law applicable?

Answer: Planetary motion

Johannes Kepler was a German mathematician and astronomer of the 17th century. He is well-known for his works on astronomy, which led to the famous Kepler's laws of planetary motion. His laws acted as the basis for Newton's laws of gravitation.
4. Amadeo Avogadro's name will always be associated with the Avogadro's law of gases. Who was Avogadro?

Answer: An Italian count

Count Amadeo Avogadro lived in the 18th and 19th century and was a professor of physics at the University of Turin. He is known for the famous Avogadro's law which stated that 'Equal volumes of ideal or perfect gases, at the same temperature and pressure, contain the same number of particles, or molecules.' The Avogadro number, which is the number of molecules in one mole, is also named after Count Amadeo.
5. With which branch of science is Hubble's law associated?

Answer: Cosmology

Hubble's law deals with cosmology and was formulated by Edwin Hubble, an American astronomer. This law acts as an important evidence for the Big Bang theory, which deals with the origin of the Universe. The famous Hubble Space telescope is named after Edwin Hubble.
6. Gregor Mendel was an Austrian friar whose name is associated with the Mendelian laws. What do Mendel's laws deal with?

Answer: Genetics

Gregor Mendel was an Austrian friar and scientist known for his contribution to the field of genetics. He studied inheritance in the pea plant. Even though his work was not recognized during his life-time, he is known by many as 'the father of genetics'. His work was re-discovered in the 1900s which led to the development of the field of genetics.
7. Which of the following is a law of economics named after a famous economist?

Answer: Keynes' law

John Maynard Keynes was a famous economist who is known for his contributions to the field of macroeconomics. His theories of supply and demand are popularly known as Keynes' law. His works dealt in great details with demand, supply, savings, etc and its role in economic growth.
Kirchoff's law deals with electricity, Boyle's law related to thermodynamics and Hering's law is associated with homeopathy.
8. An airplane flies in the sky because of the shape of its wings, which is explained by a famous law named after its creator; which is it?

Answer: Bernoulli's law

Bernoulli's law or principle deals with the field of fluid mechanics. This principle was outlined by a Swiss mathematician named Daniel Bernoulli, who lived in the 18th century. He stated that in a stream of a fluid (including air), pressure is inversely proportional to speed. So, as the air moves faster, its pressure drops.

This principle is used in aerodynamics while designing an airplane. The wings of the airplane are designed such that its top part is curved and bottom part flat. As the plane moves forward, the air blowing over the top of wing travels faster than the air that is underneath.

This greater pressure at the lower part of the wing creates a lift effect, allowing the plane to soar into the sky.
9. Archimedes was a famous Roman King, after whom the famous Archimedes law related to buoyancy is named.

Answer: False

Archimedes of Syracuse was a famous Greek scientist who lived in the third century BC. The Archimedes principle, named after him, is related to hydrostatics and states that a body that is immersed in a fluid experiences a buoyant force that is equal to the weight of the displaced fluid. According to legend, Archimedes was given a golden crown by King Hiero II and asked to test whether it was pure gold or gold mixed with silver.

While he was taking a bath, he observed that as he got in the water, the water rose.

He realized that this could be used to decide the volume of the crown, which would help him to find out its purity. He reportedly was so excited that he ran naked on the streets of Syracuse screaming 'Eureka' (I found it). This principle of hydrostatics is known as the Archimedes principle.
10. A famous principle by an economist is applied in business as '80% of sales comes from 20% of clients'. What is the principle known as?

Answer: Pareto principle

Vilfredo Pareto was an Italian economist of the twentieth century. He came out with a theory which stated that '80% of the income of Italy was in the hands of 20% of the population'. A quality management pundit named Joseph Juran applied this theory in different management areas and named it the Pareto principle, after the economist.

The Pareto principle is known as the 80:20 principle and is applied in sales as '80% of sales comes from 20% of clients'. So, the 20% clients are known as vital few and the remaining 80% as trivial many.

This principle is applied in different sectors and the Pareto chart is a statistical tool used to measure this. Lenz's law and Snell's law deal with Physics and Occam's Razor is a principle associated with scientific philosophy.
