Origins of Water

When you envision what Earth was like 4.5 billion years ago, shortly after its creation, images of dust-filled air and raging volcanoes tend to come to mind. However, amidst all that chaos, hidden within the rocks and atmosphere, what if water was also present? Traveling back to the beginning of the Solar System and Earth's formation, it turns out that Earth was partially wet from the start. with water molecules clinging to the asteroids that would later form our planet. So, how do we go about proving the existence of primordial water? And why is it so important to scientists today?


In today's episode, Tristan welcomes Dr. Lydia Hallis from the University of Glasgow to delve into the history of water's origins and explain why this research is game-changing. Drawing from research in NASA's Astrobiology archives and Dr. Hallis's own exploration in the Arctic Circle, where she scaled kilometer-high ice mountains with the help of a Red Bull athlete, we explore why the existence of primordial water on Earth is so significant and what implications it holds for the rest of the solar system.

Origins of Biological & Chemical Warfare

Origins of Biological & Chemical Warfare

The origins of biological and chemical warfare stretch far back; modern technology has not brought about these terrifying weapons. Throughout antiquity we have cases of societies using poisonous gases, incendiary materials and living organisms against their enemies. From snake and scorpion bombs to the use of ancient naphtha grenades. But how did the ancients view these infamous weapons? Did they try to refrain from using them? And if they did use them, why?I was thrilled to be joined by Adrienne Mayor to chat through this extraordinary topic. Adrienne is a folklorist and historian of ancient science at Stanford University. She is the author of numerous books including Greek Fire, Poison Arrows and Scorpion Bombs: Biological and Chemical Warfare in the Ancient World. Hosted on Acast.

Fall of the Western Roman Empire

Fall of the Western Roman Empire

In the late 4th century and early 5th centuries two massive largely-Germanic confederations arrived on Roman borders, having been uprooted from their homelands by the Huns. These were the Goths and the Vandals. Both peoples would become prime enemies of the Roman Empires in the East and West. Both would sack Rome; both played significant roles in the decline of the Western Roman Empire, inflicting terrible defeats and seizing some of the most lucrative territory in the Western Mediterranean. To talk through this ‘barbarian’ impact on the Fall of the Western Roman Empire, I’m chatting with Peter Heather, Professor of Medieval History at King’s College London and the author of ‘The Fall of the Roman Empire: A New History of Rome and the Barbarians’.

Plague of Athens

Plague of Athens

Plague in the ancient world was nothing unusual. Bouts of illness were common occurrences, but we do have accounts of some exceptional outbreaks: epidemics that brought powerful empires and city-states to their knees. One of the most infamous occurred in 430 BC: the Plague of Athens. Recently I was fortunate enough to interview Alastair Blanshard, a Professor of Classics and Ancient History at the University of Queensland, about this devastating episode in Athenian history.
