A practical combination of diagram and example. Simple is usually best.

At first I didn’t like it – too busy and radial diagrams are always annoying. Then I looked at the information and realized there was quite a lot there. Then I started looking at the legend and realized the information isn’t really clear. So now I don’t like it again.

Very nice heat chart. I wonder what would happen if you filtered by geography? An awful lot of people I knew in northern NY were born 9 months after the cold dark winter.

Brain Size and Diet

In: Science

8 Nov 2012

I love these evolutionary causation theories.

A study published yesterday in the journal PNAS puts weight behind the hypothesis that–more than any social or environmental factor–humans own their giant cognitive leap to the ancestral chefs and proto grill masters who invented cooked food.

Why? According to the researchers, a diet of raw foods can’t support an endless growth of both brawn and brains. Larger body sizes and bigger brains both meant more energy use, which meant more time spent eating each day.

And, since no primate can sustain a daily foraging requirement of much more than eight hours (gorillas average close to eight, but sometimes spend closer to nine), our ancestors must have found some way to get more energy in less time.

I don’t know that I buy the summary argument, but viewing “time spent getting calories” as a driver of intelligence and socialization selection is intriguing.

Thanks to Will T. for sending in the link!

A great diagram about different options and their efficacy. The related article goes into more detail on each remedy.

Beautiful gif illustrating simultaneous orbits.

There’s also an interactive version which allows you to do cool things like pick the year, and view Tychonian (earth-centric) orbits or zodiac houses.

p.s: sorry for not posting in a while – I was in Asia for several weeks, and while they do have internet there, I was busy exploring instead of digging up infographics:

To be honest, I get submitted so many crap info-posters, I almost didn’t catch this one. Lots of interesting content, and the animation is a nice aesthetic innovation (though probably not really necessary, of course).

Cheetah: Nature's Speed Machine, by Jacob O'Neal

In related news, the Washington DC Zoo has had a steady crop of adorable cheetah cubs the past few years. Click the link for some awww-some pictures.

Based on a Popular Mechanics review of every commercial jet crash in the United States since 1971, that had both fatalities and survivors.

In 11 of the 20 crashes, rear passengers clearly fared better. Only five accidents favored those sitting forward. Three were tossups, with no particular pattern of survival. In one case, seat positions could not be determined.

The angle threw me for a minute, and I wonder if the ending arc widths are proportionally representative or not – but overall, I like it!

We covered a lot of this data back in June, but this is a nice presentation. The addition of the global data is useful, though trying to make comparisons by switching between the two isn’t easy – a static version would probably have worked better – so here are two screenshots to help you out.

Looks awesome. I wish I knew what it all meant.

Sure, the planets orbit the sun, but it’s all moving – so it’s really moving more like this:
