Yeah, but there'd be no reason to assume it's a nitrogen/oxygen environment.
I agree with the general sentiment here, I think this planet would constitute an incredibly hostile environment to any foreign pathogen.

Yes, that's what I meant. The composition of the atmosphere can be completely different.

Live feed of lightning strikes around the world. Satisfying to just look and hear the click. I'm not sure what the black little squares are that fades away after a hit, maybe those are the strikes.

No kidding, that's an odd sensation... It's raining where I am and not lightning, but with each click...thunder. Oh, I love you, brain.

That's friggin' awesome though.

In connection to my other post, here's a similar thing but follows hack attacks around the world. Pretty entertaining to watch.

I love that there is an area of classical physics that is still so poorly understood.  Also, I am pleasantly surprised to find a lengthy article on the subject on a relatively popular website.  The subject is fluid dynamics, specifically turbulence and its measure, the Reynolds number.

I think 'poorly understood' is a bad way to put it, it's understood very well. It's just very difficult to find analytical solutions because the equations are so complicated.

This is a great watch BTW: https://www.youtube.com/watch?v=51-6QCJTAjU&feature=youtu.be&t=13m18s

Great video, thanks for sharing.  Reminds me of an article I read several years ago called Life at Low Reyolds Number, which I'm sure you've already heard of.

I hadn't read that yet! Strange article but it's very interesting, I'lll read the second half later.

Yeah, it is a bit bizzare at times, but reading it finally gave me an intuitive feel for what Reynolds number was besides some abstract measure of turbulence.

At the end, there is a reference to a publication by Reynolds called The Sub-mechanics of the Universe. The author/speaker says "[Reynolds] published a very long paper on the details of the sub mechanical universe , and he had a complete theory which involved small particles of diameter 10^{-18} cm. It gets very nutty from there on."

It's also available on amazon.  http://www.amazon.com/sub-mechanics-universe-Osborne-Reynolds-Society/dp/1418181897

I think this belongs here.  More art and technology than science and nature, but all are related.  This animated gif tells the whole story, i think.

That's pretty big news.

Meanwhile somewhere in Russia, a guy decided it's a good idea to cool your house down with frozen carbon dioxide.

Worlds darkest material created by UK scientists.  It only reflects 0.04% of light negating the ability to discern contours.  The man in the video states that if a woman wears a black dress of this material she would like a 2D cutout. Pretty cool.

There are a ton of applications I can think of for that. But now my shirts don't seem dark enough anymore.

Very cool. Fish with lungs were being raised on land, and not only did their ability to move on land improve, but the muscle and bone structure exhibited the same changes we see in the fossil record.

Well I did to see how long it would take me to be banned. Only took 28 posts, and that was with me pretending to be a god-loving, church going, white republican gun lover. I even made my username "H8Libs". I got banned the second I spoke in favor of evolution.

Even only a cursory scan of that site made it rather clear that nothing about it is "free". it's pretty obvious the only thing allowed to be posted is super hardcore rightwing.

AWESOME!  :metal That is so badass. I can't tell what that is though, I'm guessing a snake?

Man, I wouldn't wanna fall into those mofos... I fell into a pretty big bed of fire ants when I was little and nearly died but if I fell into those...shit...I'd have literally been eaten alive.

That reminds me of an AMAZING episode of Macgyver, called "Trumbo's World", where Macgyver has to fight an army of killer ants that can kill and eat people very quickly. The episode is basically stock footage of ants mixed with people screaming. I'd highly recommend it. :lol
