Established in 57 BCE, the ancient Korean kingdom of Silla lasted for more than a millennium.

Why did the Sillan practice of opulent burials end by the end of the 6th century?

Originally, his temperature scale had 0 as its boiling point and 100 as its freezing point. Who reversed the numbers after Celsius died?
