Inventors and Scientific Discoveries

Charles Robert Darwin proposed the theory of natural selection in his work 'On the Origin of Species' (1859). Natural selection explains how organisms with favorable traits are more likely to survive and reproduce. Options B, C, D have garbled variations of his name but are incorrect spellings.

This quote praising Indian mathematical contributions (particularly the decimal system and zero) is widely attributed to Albert Einstein. It acknowledges India's foundational role in developing numerical concepts that enabled modern science.

E=mc² is Einstein's mass-energy equivalence formula from his 1905 paper on special relativity. Neither Newton (classical mechanics), Hawking (black holes), nor Edison (inventions) discovered this relationship between energy, mass, and the speed of light.

Earle Dickson invented the Band-Aid in 1920 while working as a cotton buyer for Johnson & Johnson. He created the prototype for his wife Josephine, who frequently cut herself while cooking. Johnson & Johnson began marketing Band-Aids commercially in 1924, and the product revolutionized minor wound care. The name 'Band-Aid' eventually became a generic trademark for adhesive bandages.

Bette Nesmith Graham invented Liquid Paper (white-out) in 1951 while working as a secretary. She created the correction fluid using tempera paint to cover typing mistakes, and initially called it 'Mistake Out.' Her son Michael Nesmith later became famous as a member of The Monkees rock band. The product revolutionized office work and was eventually sold to Gillette for $47.5 million in 1979.

John Spilsbury, a British cartographer, invented the jigsaw puzzle in the 1760s as an educational tool to teach geography. He mounted maps on wooden boards and cut them along country boundaries.

Albert Einstein won the Nobel Prize in Physics in 1921 for his discovery of the law of the photoelectric effect, not for relativity theory which was already well-established. Option A (special relativity) is a common misconception - relativity was too controversial and theoretical at the time. Option B is humorous trivia about his appearance, not a scientific achievement.

Howard Carter, a British archaeologist, discovered the intact tomb of the pharaoh Tutankhamun in Egypt's Valley of the Kings in November 1922. This was one of the most significant archaeological discoveries of the 20th century, revealing a wealth of artifacts from ancient Egypt that had remained undisturbed for over 3,000 years.

The correct answer is C because Albert Einstein won the 1921 Nobel Prize in Physics specifically for his discovery of the law of the photoelectric effect, not for his theories of relativity (option A). Einstein's remarkable hair (option B) is not a scientific achievement, and he did win a Nobel Prize (option D is false).

The correct answer is B because Douglas Engelbart invented the computer mouse in 1964 at Stanford Research Institute. Bill Gates (A) co-founded Microsoft, John Mauchly (C) co-developed ENIAC, and Robert Noyce (D) co-founded Intel.

The correct answer is A because George Eastman invented the Kodak camera in 1888 and founded the Eastman Kodak Company. Michael Pupin (B) was a physicist, Tim Berners-Lee (C) invented the World Wide Web much later, and Alexander Graham Bell (D) invented the telephone.

Charles Taylor was the mechanic who built the first aircraft engine for the Wright brothers' flyer in 1903. He's credited as the first person to design and manufacture an engine specifically for powered flight. The similar-sounding distractor names are variations of 'Charles' and 'Taylor' rearranged.

Vladimir Zworykin, a Russian-American inventor, developed the iconoscope (camera tube) and kinescope (display tube) at RCA, crucial components for electronic television. John Logie Baird demonstrated mechanical TV earlier, Philo Farnsworth pioneered electronic TV, and Thomas Edison's work was unrelated to television technology.

Amar Bose, the MIT graduate mentioned in question 78362, founded Bose Corporation and invented the groundbreaking Bose speaker system known for its acoustic quality and noise-cancellation technology. The distractor names are variations of 'Bose' with Indian first names.

Christopher Latham Sholes invented the QWERTY keyboard layout in 1873, designed to prevent typewriter jams by separating commonly used letter pairs. This layout became the standard for typewriters and later computers. The other names are fictional or not associated with keyboard invention.
