One of the greatest challenges for most people when it comes to understanding geology is the concept of time. When our lives are measured in minutes, hours, and days, what does 3-7 million years even mean? Or 4 billion years? Explore the conventions of geologic time during this week’s installment.
About the series: Join the Geology Gents, Gavin and Graham, for weekly conversations about rocks live on Facebook. Each week we’ll explore a different geologic topic, from Santa Cruz formations to tips for being a more effective rockhound. Graham Edwards and Gavin Piccione are PhD candidates in geochronology with the Department of Earth and Planetary Sciences at UC Santa Cruz.
Submit your questions ahead of time on Facebook or by emailing events@santacruzmuseum.org, or during the program live on Facebook. Feel free to include pictures of rocks you’d like identified! Pro-tip: the better the picture, the better the ID.
ESA astronaut Matthias Maurer is currently living and working aboard the International Space Station for his first space mission, Cosmic Kiss. Recently, he experimented with water in microgravity. In this water experiments video series, Matthias demonstrates the different behavior of water in weightlessness and how this research is applied to life on Earth.
In part 5, Matthias explains how studying the behavior of water and other liquids on the International Space Station is important for numerous applications on Earth, such as in industry or food technology.
Matthias will live and work in orbit for approximately six months for his Cosmic Kiss mission. During this time, he will conduct and support more than 35 European and numerous other international experiments in microgravity.

The First Crusade was one of the most extraordinary, bloody and significant episodes in medieval history. It began with an appeal for aid from the Christian Byzantine Empire, threatened by the rising power of the Muslim Seljuk Turks. But when Pope Urban II preached a sermon at Clermont in 1095, the result was unlike anything ever seen before. The Pope offered spiritual salvation to those willing to go east to aid their fellow Christians in a holy war, and help liberate Jerusalem from Muslim rule. Knights and peasants alike signed up in their thousands, leading to the disastrous People’s, or Peasants’, Crusade, then to a much more organised and powerful Princes’ Crusade. Their forces gathered at Constantinople, where they made an uneasy alliance with Byzantine Emperor Alexius I Comnenus. Entering Anatolia, they helped to win back the city of Nicaea, then won a decisive but hard-fought victory at Dorlyaeum, before marching on the great city of Antioch…

★ The Battle of Poitiers in 1356 AD was a major encounter of the Hundred Years War. But little attention is given to the Grand Chevauchée (raid) of 1355, conducted by the Black Prince – the son of King Edward III. Chevauchée of 1355 was, in hindsight, the ‘Grand Prelude’ of sorts to the Battle of Poitiers that took place just less than a year later.
Although no battles were fought and no territory conquered during the Chevauchée of 1355, southern France was utterly devastated. The destruction of the rich countryside and urban areas, and the atrocities against the civilian population are among the most brutal military campaigns of the medieval period.
This video is part 1 of a two-part mini series about the Battle of Poitiers, 1356 AD.

The Battle of Poitiers in 1356 was the second major English victory of the Edwardian phase of the Hundred Years’ War. The effect of the defeat on France was catastrophic. Years of political turmoil and civil unrest followed, leading to a humiliating treaty at Bretigny in 1360, which saw huge portions of the French kingdom ceded to England.
