Colorful glowing crystal with green and yellow hues

about.me

I’m Pascal. Geology is incredible, but it has a PR problem. Most of it is either trapped in dense textbooks or flattened into outdated media, and there’s very little in between. I built Geoscopy to fill that gap — high-definition video and deep-dive essays for people who want to learn geology: in an understandable version not a simplified version.

You’re walking on 4.5 billion years of history every day. I’m showing you how to read it.
