  • Are all people on Earth really connected through just six steps? SEND ME AN EMAIL: 1. Do not send it directly to me unless you know me. 2. Send the email to someone you have met IN PERSON and know on a first name basis AND THEY KNOW YOU. 3. Make the subject line 'Six Degrees of Veritasium' 4. Explain that you're trying to get this email to me and ask them to forward it on to me (only if they know me IRL) or someone they know who might know me. 5. If your email reaches me by Sept. 1, 2015 I will email you back and ask for your address so I can send you a postcard. Animations in this video by The Lyosacks: https://www.youtube.com/user/TheLyosacks There are some great books on this topic: Duncan Watts, Six Degrees: The Science of a Connected Age Albert-Laszlo Barabasi, Linkds: How Everything is Connected to Everything Else And here are articles I referred to: Milgram's small world experiment: http://www.uvm.edu/~pdodds/files/pape... http://snap.stanford.edu/class/cs224w...

  • You guys can stop emailing me now.

  • I have exactly 44 less than 44 friends

  • "Imagine you have 44 friends"

  • This six degrees of separation becomes even more interesting when you add an element of time to it. Say for example, how many degrees are there between you and a historical figure? Obviously the further back in time the figure you are wanting to connect with the greater the number of degrees of separation. This can make it really interesting to know old people who have themselves known old people in their younger days. You may not get to experience history first hand but even so second and third hand may provide a greater degree of insight than you would get from newspapers or even history books. In my case, perhaps two decades ago now I spent some time with a man in his eighties who as a child had spent time with an older figure, allowing me to time travel a century and a half.

  • The looks you are getting from those people is like the highlight of the video


  • That fully explains the thing on steam:

  • did you really travel to manila just to say like here in manila?

  • "imagine you have 44 friends"

  • I'm pretty sure every Wikipedia page is 6 or less clicks away from Hitler's page

  • is there a follow up video about how the experiment went?

  • I have 4 friends on facebook, and I know none of them

  • lol all those people just walking through your shot and looking at you like wtf is he doing, wheres the camera

  • He had me at "Six Degrees of Kevin Bacon"

  • Since this is from last year it's possibly buried somewhere in the comments but....I'm curious how many postcards were sent.

  • Literally the basis of the Wikipedia game

  • So when waging war on the other side of the world, we're killing people that are only 6 degrees of separation apart from us... kinda gives "the enemy" a familiar face..

  • So, did anybody actually do it and received a postcard?

  • I am Armenian and I live in Moscow, Russia. (just so you have an idea of how little I have to do with US) Couple months ago my father invited one of his business acquantances to our house as a guest. We soon found out that the daughter of that man is married to.. Jim Carrey. To say that I was absolutely blown away is to say nothing :) here sits a man in front of me that is at this point a father to one of the greatest actors of our day and a star of my childhood

  • This reminds me of that guy who started with a red pen and via trading he ended up with a house
