These podcasts are just the audio from my Youtube videos. If you'd like to see visuals too, visit my channel, Let's Find Out:   Science evolved, emerged and emancipated humans out of our long past. It's helped us more sharply define the world around us and use it's immutable forces for our own purposes. It's given us a standard of interpreting the world. It's shown us how insignificant Earth is in size, and how impossibly rare it is in complexity. It's redefined our destiny in the cosmos, and that's why I wanted to know it's history. I hope your share in the wonder of how powerful a cognitive tool science is for humanity. Thanks for watching.
