What is the CRiO online institute?

CRiO is an international online education program with the highest standards for content and quality from a recognized researcher who is deeply active in cutting-edge research.

The CRiO online institute is composed of a weekly interactive video-based training program in a classroom-style setting that appeals to any passionate individual who wants more knowledge and more understanding of the scientific world view.

How it works

CRiO online institute offers you instant access to on-demand lectures and other materials as they are produced. We offer high-level content with one click.

Video Lessons

Course presentations are provided in video lecture format, and are scheduled to be released in weekly module sets. Each video averages about 30 minutes.

Downloadable Resources

We offer downloadable resources such as supplementary readings, study sheets or other materials.


Another unique aspect of our course are scheduled interactive times akin to "office hours" and "recitations". Your Professor will answer your submitted questions.

What you will learn

​​Program Overview

What is the origin, structure, composition and dynamics of the Earth? What is the chemical make-up of the materials that compose the planet, their mechanical properties and how they operate and interact in different processes (e.g. weathering, denudation, plate tectonics, volcanism, metamorphism, etc.) over millions of years to yield the planet we know today?

Is the CRiO online institute right for me?

Is your passion to acquire better scientific knowledge of the natural world? To gain a firmer grasp of new research as it unfolds? To understand what these discoveries actually mean? Or perhaps even to get advice on how to navigate the difference between the mythological world view and the scientific world view?

Whether you’re an ambitious beginner, budding scientist, active researcher, armchair enthusiast, retiree, consultant or artist of life, the CRiO online institute offers you the credible content you have been looking for. CRiO does this without the irrelevant bells and whistles and philosophical arguments, and gets right to what matters in the subject.

Students are raving!

“After I completed his class at the University of Colorado, I signed up for every other course that he taught afterwards! He makes science fun and understandable, and has a great sense of humor!”


D. Trail

Boulder, CO & Rochester, NY

“I have attended lectures presented by Professor Dr. Mojzsis at several public events. His enthusiasm and the way he articulates geology, astronomy and biology all together into a coherent narrative is unique.
Furthermore, I saw several television shows that featured his work, including PBS-Nova and BBC-The Planets, that were truly outstanding thanks to his contributions. Recently, he was the opening presenter on the PBS program "H2O - the molecule that made us"; it literally took my breath away.
I am very thankful that Steven created this online institute, so I will be able to continue to learn and to look at the world we live in with different eyes."


S. Harman

Boulder, CO (USA)

“I have learned so much from Stephen. I am excited about science and listening to Stephen talk brings complex ideas into focus for me. I was lucky to meet him in person and have had incredible deep conversations about nature that brought my level of understanding to a higher level.”


M. Blank

This online institute is dedicated to sharing the knowledge, tools and resources you will need to change your perspective of our place in the Universe and to also have fun in an inquiry-based way.

We call our online platform the

Why join

4 reasons why the CRiO online institute
is the best choice for You:


We are here because we desire to seek out and share knowledge just for the pleasure of doing so. People like you who are curious about science do this because they want to know the answers to the mysteries of the natural world.


Credibility in science is based on the method-based investment of working towards a reliable and testable picture of how the universe works. Ingenuity, experience, and perception are decisive in this endeavor, but there is no substitute for meticulous effort and healthy skepticism. 


Science creates in ways that differ from the humanities and its disciplines art, music, and literature. These are inspired toward innovation by using imagination to portray the real or imagined. Scientists instead build explanations by linking together bits of information in a way that makes sense - to construct what are known as theories - that have the power to predictively guide our search for more. Science and Art are complementary, but intrinsically different in world view. A talented and balanced individual learns to embrace both.

Cutting edge

We strive to be at the leading edge of ideas by harnessing our creativity via credible sources, that feed our curiosity to know more.
