Answer Key

Question 1
A. Isaac Newton

Isaac Newton published his three laws of motion in 1687 in his landmark work 'Principia Mathematica.' Legend says a falling apple inspired his theory of gravity.

Question 2
A. E = mc²

Einstein's equation E = mc² shows that energy and mass are interchangeable. He published his theory of special relativity in 1905, his 'miracle year.'

Question 3
D. Physics

Marie Curie won the Nobel Prize in Physics in 1903 for her work on radioactivity. She later won a second Nobel in Chemistry in 1911, making her the first person to win two.

Question 4
C. Evolution by natural selection

Darwin published 'On the Origin of Species' in 1859 after years of research, including his famous voyage on HMS Beagle to the Galápagos Islands.

Question 5
C. Pasteurization

Pasteurization, named after Louis Pasteur, involves heating liquids to kill harmful microorganisms. He also created the first vaccines for rabies and anthrax.

Question 6
C. The Earth orbits the Sun

Galileo supported the heliocentric model — that Earth revolves around the Sun. The Catholic Church put him under house arrest for the last nine years of his life for this belief.

Question 7
A. Alternating current (AC)

Tesla championed alternating current (AC) in the famous 'War of Currents' against Edison's direct current. AC became the standard for power transmission worldwide.

Question 8
C. The phonograph

Edison invented the phonograph in 1877, the first device to record and play back sound. He also developed a practical incandescent light bulb and held over 1,000 patents.

Question 9
B. Black holes

Hawking theorized that black holes emit radiation (now called Hawking radiation). Despite living with ALS for over 50 years, he became one of the most celebrated physicists ever.

Question 10
B. Penicillin

Fleming noticed that mold on a petri dish was killing bacteria, leading to the discovery of penicillin — the world's first widely used antibiotic, saving millions of lives.

Question 11
B. DNA

Watson and Crick described the double helix structure of DNA in 1953. Their work relied heavily on X-ray crystallography data from Rosalind Franklin's laboratory.

Question 12
B. The periodic table of elements

Mendeleev published his periodic table in 1869, arranging elements by atomic weight. He even predicted the existence and properties of elements that hadn't been discovered yet.

Question 13
A. Buoyancy

According to legend, Archimedes discovered the principle of buoyancy while taking a bath and ran through the streets shouting 'Eureka!' meaning 'I have found it!'

Question 14
A. DNA

Franklin's famous 'Photo 51' X-ray image was key evidence for the double helix structure of DNA. Her contribution was largely unrecognized during her lifetime.

Question 15
A. Electric motors and generators

Faraday discovered electromagnetic induction in 1831, which is the principle behind electric motors, generators, and transformers that power our modern world.
