Question 4

In medieval Islamic measurement, which unit was standardized by a caliph who commissioned a black granite master rod kept in a Baghdad treasury so that tax collectors across the empire would all use the same length?

Accepted Answer

The cubit. The dhira, or royal cubit, varied wildly across regions until Abbasid rulers had a reference rod carved and distributed copies to provincial administrators.

Question 5

Many people believe Christopher Columbus proved the Earth was round — but educated Europeans already knew the Earth was spherical. What did Columbus actually get badly wrong?

Accepted Answer

He drastically underestimated the size of the Earth. Columbus calculated the Earth's circumference as roughly 19,000 miles — about 25% too small. He thought Asia was located where the Americas turned out to be. He died believing he had reached Asia, never accepting that he had encountered an entirely unknown continent.
