Question 1

Which physicist won the Nobel Prize for discovering the photoelectric effect — NOT for his more famous work on relativity?

Accepted Answer

Albert Einstein. Albert Einstein won the 1921 Nobel Prize in Physics for explaining the photoelectric effect, not for the theory of relativity. The Nobel Committee considered relativity too speculative at the time.

Question 2

Which country introduced the world's first national fingerprint identification system used for criminal investigations, doing so in the 1890s under a police officer named Juan Vucetich?

Accepted Answer

Argentina. Argentine police officer Juan Vucetich developed the first scientific fingerprint classification system and used it to solve a murder case in 1892, making Argentina the pioneer of fingerprint forensics.

Question 3

In professional cycling, what is the name of the brutal 295-kilometer single-day race through northern France that runs partly over cobblestone farm tracks called 'pavés,' earning the nickname 'The Hell of the North'?

Accepted Answer

Paris–Roubaix. Paris–Roubaix is one of cycling's Monument classics, notorious for its treacherous cobblestone sections. The winner receives a cobblestone as a trophy rather than a conventional prize, symbolizing the race's brutal terrain.

Question 4

What is the name of the effect where spinning a hard-boiled egg causes it to stand upright on its own, a phenomenon that stumped physicists for decades?

Accepted Answer

Jallett's Effect. When a hard-boiled egg is spun rapidly on a flat surface, friction and gyroscopic forces cause it to rise and balance on its tip — a behavior that wasn't mathematically explained until 2002.

Question 5

In music theory, what is the term for a chord that uses four notes stacked in thirds, often creating a jazzy or bluesy sound?

Accepted Answer

Seventh chord. A seventh chord consists of four notes — a root, third, fifth, and seventh — and is a cornerstone of jazz, blues, and R&B harmony. The added seventh note gives it a richer, more complex sound than a basic triad.
