Colorful glowing crystal with green and yellow hues

about.me

I’m Pascal. Geology is incredible but it has a PR problem—usually trapped in dense textbooks or outdated media. I built Geoscopy to change the narrative. I’m archiving the planet’s history through high-def video and deep-dives for people who want the raw science, not the “lite” version.

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