Correct answer: CIsaac Newton
Sir Isaac Newton laid the classical foundation of mechanics, demonstrating that earthly and celestial bodies follow the same mathematical principles.
Correct answer: AAlbert Einstein
Albert Einstein revolutionized theoretical physics by describing the equivalence of mass and energy and the curvature of spacetime.
Correct answer: BMarie Curie
Marie Skłodowska-Curie won in Physics in 1903 for research on radiation and in Chemistry in 1911 for discovering polonium and radium.
Correct answer: DCharles Darwin
Charles Darwin gathered vital observations aboard HMS Beagle, developing a cohesive mechanism for how species adapt and diverge over time.
Correct answer: AAlexander Fleming

Correct answer: BNikola Tesla
Nikola Tesla patented key AC generation and transmission designs, which became the global standard for high-voltage power distribution.
Correct answer: ADmitri Mendeleev
Dmitri Mendeleev organized elements by atomic weight and predicted the physical properties of then-unknown elements like gallium and germanium.
Correct answer: BJames Watt
James Watt prevented wasteful cooling and reheating of the engine cylinder, powering the industrial mechanization of factories and mines.
Correct answer: CGalileo Galilei
Galileo's telescopic discoveries of Jupiter's moons, lunar craters, and Venus's phases provided empirical evidence supporting heliocentrism.
Correct answer: BLouis Pasteur
Louis Pasteur proved that microorganisms cause fermentation and disease, developing heat-treatment pasteurization to destroy pathogens in liquids.
Correct answer: AAda Lovelace
Ada Lovelace translated Luigi Menabrea's notes in 1843 and appended her own stepwise method to calculate Bernoulli numbers using the machine.
Correct answer: AOrville and Wilbur Wright
The Wright brothers achieved the first controlled, sustained, and powered heavier-than-air flight at Kitty Hawk, North Carolina.
Correct answer: BJames Clerk Maxwell
James Clerk Maxwell unified electricity, magnetism, and optics into a coherent set of four partial differential equations.
Correct answer: BAlessandro Volta
Alessandro Volta stacked alternating discs of zinc and copper separated by brine-soaked cloth, generating the first continuous electric current.
