This week we have the second part of Junjie Dong’s insightful blog on modeling the early Earth. Following the discussion (“Modeling the Early Earth: Idealization and its Aims I”) about the major early Earth questions and challenges in modeling early Earth, Junjie now explores  the imprtance of modeling as a scientific endeavor. He presents how one could more effectively model the ...[Read More]

The question of how we came to be is closely tied with how the Earth became what it now is. What was the early Earth like? How did it evolve to become a habitable world? Given a fragmentary rock record, how can we investigate the early Earth and its evolution? Dr. Junjie Dong from Caltech writes about modeling the early Earth in a two-part blog.  For the first part, he introduces the approach to e ...[Read More]

Geodynamics: It’s in the air we breathe!

and July 20, 2022

Have you ever wondered how Earth became habitable. In this week’s news and views, we have Fabio Capitanio, Associate Professor at Monash University sharing insights into the role Geodynamics in the evolution of Earth and life on it. Our planet has unique features which make it suitable for life. Understanding how the Earth became habitable is necessary to answer the most fundamental question ...[Read More]

2021: 100th year of the craton concept and beyond
Life on a craton, Hampi, India

One hundred years back, Leopold Kober first introduced the term “Kratogen”. With time, the concept of kratogen has evolved, and they are now known as cratons. In this week’s news and views, Jyotirmoy (@GeophyJo), a PhD student from the Indian Institute of Science revisits the history of craton science: how the craton concept has evolved and what are the modern problems related to them.   &nbs ...[Read More]
