Welcome to the latest episode of Rocks for Jocks! Today, we jump into the fascinating earth science discoveries I learned about during my trip to Iceland. I discuss Iceland's position on the mid-Atlantic Ridge, witness the breathtaking sights of a national park, and discover how magma, hot springs, and geysers interplay to create stunning natural features. Listen here!

01:43 Exploring Iceland's Tectonic Activity

03:23 The Formation of Iceland's Landscapes

06:13 Geysers and Their Mechanisms

09:17 Conclusion and Upcoming Topics

In this episode, I interview Rob Baxter, CEO and founder of CBC Wind Energy. We talk about the mechanical resilience, environmental impacts, and minimal infrastructure of CBC’s wind turbines, which are especially useful in disaster relief areas. Rob also shares insights on the broader role of renewables in diversified energy portfolios and offers advice for entrepreneurs in the energy space. 

01:18 Innovative turbine designs

06:58 Cost and Efficiency of CBC's turbines

12:26 Optimal and extreme conditions 

20:00 Environmental impacts & challenges

28:06 Advice for renewable energy entrepreneurs

Privately funded Spacewalks! What are they? Why do they matter? Are they good or bad? Let's find out!

Spacewalks are when astronauts leave their shuttle in outer space and are completely reliant on their spacesuits to keep living. Listen here to learn more!

Today, we're sharing a conversation with Laura Huepenbecker. With notable contributions to several professional movie and podcast productions, Laura continues to be a leader in the environmental media space. We talk about Laura’s experiences on a farm set for 3 years, soil research, and sheep pupils!

Alex jumps into the third and final part of his summary and review of Stephen Hawking's 'The Theory of Everything’. Lecture 6 covers the concept of time using thermodynamic, psychological, and cosmological arrows. Lecture 7 explores the search for a unified theory and its philosophical impacts (we promise no more big words).

In this episode, I dabble in lectures 3 through 5 of Stephen Hawking’s book, ‘The Theory of Everything’. We are talking Hawking’s shocking explanations of stars, black holes, and the Big Bang! Hawking tells a joke about the pope. I explain surface area using a baseball as an analogy — sports! I even ruminate briefly on how I imagine an infinite universe.

In this episode, I interview Adel Asadi, PhD, who talks about his journey from Iran to Stanford University. Adel shares details from his academic career, including his achievements in mining, machine learning, and geohazards. He also offers a glimpse into his ongoing postdoctoral work and entrepreneurship at Stanford.
