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. Forever. #YouCanLearnAnything Subscribe to Khan Academy’s Cosmology & Astronomy channel: https://www.youtube.com/channel/UChNPnEkW8LYZ5Rwi8_A2-DA?sub_confirmation=1 Subscribe to Khan Academy: https://www.youtube.com/subscription_center?add_user=khanacademy

Great video. Explains a lot that i have never considered.

Love the video.

Never posted on Khan Academy before but if you plot human saccharomyces cerevisiae on with human expansion you will see they correlate and the reason for that is that brewing microbes from water, so alcohol is one of our important discoveries. Still though no doubt Agriculture is the most important aspect of human history and future.

Weren't we supposed to be learning astronomy?

I don't think so, natural selection occurs because species adapt to the environment to survive. Seeing as how we have colonized the planet we have nothing to adapt to. I think if anything the next step in human evolution will be integration of technology in the human body.

Noobs response. Being a hunter gatherer gives you more spare time than toiling in a field all day. Writing and scientific advancement was made by the higher classes who were free of work.

Success for Managers is: Respect. To be paid to think, not just to comply. To be trusted.

This is a great video, but I think Khan left out (whether purposely or accidentally) a huge reason why agriculture was important. Settling down with a steady supply of food meant that we no longer had to base our lives around finding food, instead now we had more free time, which allowed us to develop special skills.

@JosephLoegering For the too many Negative Notes, some falsely so called scientists out of touch reality and disobedient to Court Orders took me to court for my Religious Posts that the Judge would not accept because it was persecution, but them People disobeyed Court Ordered and forced drugs on me that were known to cause me harm and I still cannot get Medical attention for the internal bleeding that they caused, because they are like Scientists of Nazi Germany, totally insane and inhumane

I think it's supposed to be pronounced cu-NAY-if-form sal

looks like the beginning of a new series of videos :D
-
Great video!
-
@armpitpuncher more of a Bud. xD
-
@Acerola211 Thanks for the clarification. :)
-
@christerryatl Well, I think we can all agree that agriculture made humanity the way it is today. There's definitely a lot of positive outcomes, but I do agree that there are some negative outcomes, as well. I think it's good to be grounded in reality.

@Emanresu56 The textbook says, "Natufian settlements [the people who've settled due to abundant wild grains rather than because they started farming] . . . show permanent architectural features and evidence for the processing and storage of wild grains. One such site is Abu Hureyra, Syria, which was initially occupied by Natufian foragers around 11,000 to 10,500 B.P." It sounds to me that these archaeologists didn't find farming tools but permanent settlements based on wild grains in that area.

Thanks! A good beginning for a series on farming... all very interesting and good. Maybe next lesson will be about the best way current day to use farm land (and/or individual properties) to produce enough diverse foods to feed a local community.

Stone Age -> Metallic Ages -> ???

@BitterBurst Blue-rare steak is delicious, and when I was really into weight training I used to shoot raw eggs, but that tasted disgusting. That said, it can be pretty hard to beat a charbroiled burger with the right seasoning.
-
@BitterBurst It's totally fine to eat any meat of fish raw, as long as it hasn't gone rancid, with the exception of chicken. Maybe a couple other exceptions too, but I eat my meat mostly raw and I'm healthy as a horse :)
