What Can Frogs See That We Can’t?

April 17, 2013

What Can Frogs See That We Can’t? Check out the original double slit experiment: http://www.youtube.com/watch?v=Iuv6hY6zsd0 – oh, and for the sun to be seen as single photons, you would have to be ~1000 light years away, so well past Pluto. For clarification on this video, please see: http://www.youtube.com/watch?v=OW7tfrTh66c What would you see if you were drifting through space, looking back at the sun? Well its light intensity would decrease as the inverse square of distance from the sun. And you would imagine the intensity would decrease smoothly, asymptotically approaching zero. But this is not what happens. If you had sensitive enough eyes, like frogs’ eyes, you would find that at some point the sun would start to flicker. You would see flashes of light separated by complete darkness. And as you drift further from the sun, what’s strange is that these flashes do not decrease in brightness, but they do become less frequent. That’s because light comes in lumps, called quanta or photons, which are indivisible. So if you try to spread light out very thinly, you reach a point where there are only single bits of light reaching an observer’s eye at any given time. I should acknowledge the book “The Fabric of Reality” by David Deutsch, which contains a similar story about a frog and a torch. It inspired me to make this film. Thanks also to MinutePhysics for reviewing earlier drafts and suggesting I make it more ridiculous. From: 1veritasium Views: 202474 6194 ratings Time: 03:06 More in Education

Pastor Sean Harris Tells Congregation to Punch Their Gay Sons

May 4, 2012

Pastor Sean Harris Tells Congregation to Punch Their Gay Sons NOTE: I'm posting this NOT as an endorsement. I think this is one of the most offensive things I've ever seen from the pulpit. I'm just sayin…. Pastor Sean Harris of Berean Baptist Church in Fayetteville, NC tells congregants to break the limp wrists of effeminate boys and essentially “beat the gay away” from their kids. He has offered a lame apology (see justification) on his blog at http://pastorseansblog.blogspot.com/2012/05/important-clarification-to-sundays.html. I hate to tell him, but his “clarification” just reinforces the thrust of his violent message. From: littlebluealien Views: 78196 1201 ratings Time: 02:06 More in News & Politics
