I dare you to watch this entire video. It’s neat, I promise:
A nice little story about a boy, his motorcycle, his grandfathers, and his mother:
It’s an astronomy story I knew before, but this presentation is good enough and awe-inspiring enough to share:
The ways in which science — especially around health and nutrition — is abused is a bit of an old saw here: see the sensible science skepticism tag. So when I heard this talk from Ben Goldacre which I’d never linked, I knew I had to even though it’s quite old. Worth a watch for sure. (The talk I did link is great too.)
This isn’t new by a long stretch, but it’s an awesome map: animating the spread of Walmart in its growth out of Arkansas and across the US. It cuts off in 2010, and inspired an animated GIF made with Excel. (!?) The GIF is below:
I looked this up in part because of a recent post from Shane Parrish which quote’s Sam Walton’s explanation of their strategy:
We figured we had to build our stores so that our distribution centers, or warehouses, could take care of them, but also so those stores could be controlled. We wanted them within reach of our district managers, and of ourselves here in Bentonville, so we could get out there and look after them. Each store had to be within a day’s drive of a distribution center.
We saturated northwest Arkansas. We saturated Oklahoma. We saturated Missouri. We went from Neosho to Joplin, to Monett and Aurora, to Nevada and Belton, to Harrisonville, and then on to Fort Scott and Olathe in Kansas —and so on.
Charming little video about a old man who’s living a nice simple life as the most recognized face on San Diego’s Pacific Beach.
The most lasting thing I took away from the news of the discovery that gravity waves exist — still an idea I’m not sure I fully comprehend — is Jason Kottke’s enthusiasm for this video in which the creator of gravity waves theory discovers it has been discovered:
The commentary Jason has added, about what exactly the revealing scientist is saying, is great too:
Many people have asked what Kuo is saying to Linde on the doorstep. Let’s start with “5 sigma”. The statistical measure of standard deviation (represented by the Greek letter sigma) is an indication of how sure scientists are of their results. (It has a more technical meaning than that, but we’re not taking a statistics course here.) A “5 sigma” level of standard deviation indicates 99.99994% certainty of the result…or a 0.00006% chance of a statistical fluctuation. That’s a 1 in 3.5 million chance. This is the standard particle physicists use for declaring the discovery of a new particle.
