Richard Feynman Explains the Origins of Trees
In this clip, renowned physicist Richard Feynman provides a simplified explanation of how trees grow. He describes the process of photosynthesis, noting how trees take carbon dioxide from the air and use energy from the sun to build their structure. Feynman, known for his ability to communicate complex scientific concepts in an accessible way, breaks down the biological mechanism of how trees essentially pull matter from the atmosphere. The video highlights his unique teaching style, which focuses on the fundamental physical processes behind everyday natural phenomena.

the oxygen in the air comes from the water.... the co2 oxygen stays in the tree
I would argue it comes out of the Sun...
My favourite American
Amazing mind. One of the greatest teachers.
Give that guy another marijuana cigarette.
People in the comments don't seem to know who that fella is. That's famed percussionist Richard Feynman!
Wait untill you read how much happens for your finger to move
So firewood is a form of solar power.
That's actually pretty accurate to what is happening, yet oversimplified.
He’s not wrong but he’s explaining it like he just took a massive hit out of a bong and the realization hit him suddenly and he needed to share it
