If you're listening to this, chances are that you have seen a snowflake, or perhaps a few billion covering the streets or ski slopes. Maybe you’ve even caught one on your tongue. But despite being such a common part of nature, until recently, snowflake formation largely remained a mystery.

Today, I’m thrilled to be joined by Dr. Kenneth Libbrecht, a renowned expert in the field of snowflake physics.

Dr. Libbrecht is a professor of physics at the California Institute of Technology, where he has been studying the mysteries of snowflakes for more than two decades. His research has helped to demystify some of the longstanding questions surrounding these complex and beautiful crystals.

Dr. Libbrecht and his work has been featured on NPR, Scientific American, The New York Times, and many other publications. In addition to his work as a physicist, Dr. Libbrecht has authored multiple books about snowflakes, had his photos featured on US Postal Service stamps, and even served as a snowflake consultant for the popular Disney movie Frozen.

In my conversation with Dr. Libbrecht, we explore the world of snowflake crystals, learn how they form and why they usually have 6 sides. Dr. Libbrecht discusses his discoveries and his innovative lab, and provides a primer for finding and photographing snowflakes. We also talk about snow in general, such as why some snow is light and fluffy, while other snow is heavy and dense, why a particular bacterium plays a role in artificial snow production at ski resorts, and what "diamond dust" is.

And if you do nothing else, check out Dr. Libbrecht and his lab in the Veritasium video called “Why are snowflakes like this?” - it’s fascinating. You can find it on YouTube, or linked in the show notes.

And if you are a naturalist stuck inside in the winter, or visiting somewhere cold, take a moment and go outside, catch some flakes, and see what you've been missing. And be sure to check Dr. Libbrecht’s website, snowcrystals.com, for photos, facts, science, projects and more!
