How symbolic language drives collective learning and how this is one of the truly differentiating aspects of human beings relative to the rest of the animal kingdom. Created by Sal Khan.

But the Sun is tiny compared to the solar system which is tiny compared to the distance to the next star. Oh, did we mention that there are over 100 billion stars in our galaxy (which is about 100,000 light years in diameter) which is one of hundreds of billions of galaxies in just the observable universe (which might be infinite for all we know). Don't feel small. We find it liberating. Your everyday human stresses are nothing compared to this enormity that we are a part of. Enjoy the fact that we get to be part of this vastness! About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content. For free. For everyone.

i just learned something new... good feeling

Imagine in the far future if we could encode all of mankinds important knowledge onto part of our dna and through genetically engineering or computer inhancement change our brains to be able to read and understand the encoded dna somehow. Then one day maybe humans would be born with the knowledge of the universe and the knowledge of their ancestors.

man man dog dog eats dog, man man dog eats dog, man man eats dog, man eats man

@eatcarpet We taught them through our learning style. They can't convey this to other apes

@khanacademy What is this "Big History" project?
-
What's this doing in the astronomy playlist ?
-
@noxure lol

@LeathaFace17 I wish more humans would learn our secret too.

I love it how you said "dog eats man" without flinching. But "man eats dog" was followed by "unpleasant" and "maybe in a desperate situation" haha
-
Ok so what is better than human_symbolic lang.
-
@hedonism13 yes, I need to separate them out. I've been doing these all as part of the "Big History" project

Though the flow of presentation has been good, the material presented can rarely make a good introduction.

I've finished school for the year and I'm still watching his videos :D
-
I don't understand the cosmology and astronomy playlist. Some of the videos in it seem better suited to a seperate "Anthropology" or "Geography" playlist.
