Question 1

Which planet in our solar system has a Great Red Spot that is actually a storm larger than Earth itself — and has been raging continuously for at least 350 years?

Accepted Answer

Jupiter. Jupiter's Great Red Spot is a high-pressure anticyclonic storm roughly 1.3 times the width of Earth. Astronomers have tracked it since at least the 1660s, though it has been slowly shrinking in recent decades.

Question 2

Many people think Vikings wore horned helmets — but that's almost entirely a myth. Where did this popular misconception actually come from?

Accepted Answer

A 19th-century costume designer's outfit for a Wagner opera production. The horned Viking helmet image was largely popularized by costume designer Carl Emil Doepler, who created horned helmets for the first production of Wagner's 'Der Ring des Nibelungen' in 1876 — the theatrical look spread into popular culture and stuck.

Question 3

Which Mesoamerican civilization developed the most accurate calendar in the ancient world, with a solar year calculation accurate to within 17 seconds?

Accepted Answer

Maya. The ancient Maya calculated the true solar year at 365.2420 days, which was remarkably close to the actual 365.2422 days and far more accurate than Europe's Julian calendar. However, their solar calendar, the Haab', remained a fixed 365-day cycle, as Maya astronomers tracked the fractional drift in separate astronomical calculations rather than using leap years.

Question 4

The element mercury is the only metal that's liquid at room temperature — but which other element on the periodic table is also a liquid at room temperature, making it one of only two?

Accepted Answer

Bromine. Bromine is the only other element that is liquid at standard room temperature and pressure. Unlike mercury, bromine is a non-metal — it's a reddish-brown, extremely corrosive liquid that belongs to the halogen group.

Question 5

The music term 'limelight' — meaning the spotlight of public attention — originally referred to a literal lighting technology. Where did it come from before it became a metaphor?

Accepted Answer

Burning lime used to illuminate 19th-century theater stages. Limelight was a brilliant stage lighting technique developed in the 1820s where burning calcium oxide (lime) produced an intensely bright white glow — it was so dazzling that being 'in the limelight' naturally came to mean being the center of attention.
