Cool Scienc-y Stuff

Here's a couple of interesting and fun science-related things that were in my RSS feed this morning.

First comes this great article on our time in space over the past number of years.  Hat-tip to fellow amateur radio operator Jeff, KE9V at his Pertubation blog for bringing this article out.  Go visit his blog, you'll be glad you did.  Here's a link to the article, 5,200 Days in Space at The Atlantic.

And from The Polymath Post, a lesson on the physics of falling dominoes.  I've embedded the video directly here, but do follow The Polymath Post.  They offer great content each week.
