The people of Ancient Mesopotamia practiced mathematics from the early days of Sumer to the fall of Babylon in the 6th century. Until recently, most evidence suggested that math was used primarily for things like measuring land. A new discovery by a researcher in Berlin has shed new light on how Babylonians used geometry to measure the changes in the velocity of Jupiter over time as it moves across the sky. Prior to this discovery, the use of geometry in this manner was thought to have come in the middle ages. Listen to hear how this new discovery shows that Babylonian mathematics was more sophisticated than previously thought.

It’s a modern-day story of protecting artifacts in war zones and is tied to the many ancient artifacts that have been lost over the centuries.
The process by which our modern calendar was created was difficult. This public radio story describes the Julian calendar developed during the rule of Julius Caesar in Rome in the first century BCE, and how this calendar failed to keep accurate time for the Catholic Church centuries later. You will hear how Pope Gregory called on modern science to create an accurate calendar in the 1500s and that became the calendar we use today.
In 2014 astronomers discovered a new dwarf planet on the edge of the solar system. This discovery has changed scientists’ understanding of what exists in the solar system beyond the more well known dwarf planet Pluto. The new planet is a pink ball of ice and scientists believe there could be an unseen and undiscovered planet larger than Earth in the far reaches of our solar system.
Archeologists have long searched sites across Central America to learn about the ancient civilizations that once thrived there. One of those civilizations is the Olmecs, an early Central American people, whose culture pre-dates the Mayans. In this audio story you will hear about the discovery of a stone block that seems to date back to the Olmecs, over 3,000 years ago. It contains what might be the oldest writing ever found in the Americas. Listen to learn more about the significance of this discovery.
