20 Notes


If you took a picture of the sun at the same time each day, would it remain in the same position? The answer is no, and the shape traced out by the sun over the course of a year is called an analemma. The sun’s apparent shift is caused by the Earth’s motion around the sun when combined with the tilt of the Earth’s rotation axis. The sun will appear at its highest point of the analemma during summer and at its lowest during winter. Analemmas created from different Earth latitudes would appear at least slightly different, as well as analemmas created at a different time each day. The analemma pictured here was built up by sun photographs taken from August 1998 through August 1999 from Ukraine.

Martian Skies

Alan Taylor collects over a dozen photos of the Martian landscape and atmosphere, each one remarkable and surreal.

I love the photo with the second probe and its parachute.

If you can’t explain it simply, you don’t understand it well enough.

I just broke the 10,000 song barrier in my iTunes library.
The lucky album was Cave In’s Jupiter.

Notes

Hacker and writer Joshua Klein is fascinated by crows. (Notice the gleam of intelligence in their little black eyes?) After a long amateur study of corvid behavior, he’s come up with an elegant machine that may form a new bond between animal and human.

I remember reading about the work he did, but to see him speak is really great.

I think this is my favourite TED Talk so far.  Although there was one about Space travel and new photographs of a planet (I think it was Jupiter) that I saw a few months ago, where the lady giving the talk was so passionate and emotional that it gave me goosebumps, but I can’t find it on the site.

Isolated tribe spotted in Brazil 
“One of South America’s few remaining uncontacted indigenous tribes has been spotted and photographed on the border between Brazil and Peru.”  (Via BBC News).
Look at these guys - ready to attack a plane with their spears!  And why are two of them painted red and one of them painted black?  And a hundred uncontacted tribes?  And so many other questions.  I guess the world is still a pretty big place.  More photos here.

I took this a couple of weeks ago, after it had rained for the first time in a while.  I noticed that there were drops of water falling from the roof of a shed onto an old brick on the ground and realised that the hole you can see in the brick had been made by the same drops over the last few years.
Nothing special, I know.  Basic physics and geology and it’s probably not on the same level as, say, the Grand Canyon but for whatever reason, I liked it.
I spent about ten minutes trying to capture a splash and this was the best I got.

This is brilliant, one of those “why haven’t we been doing this for years?” moments…

Direct Manipulation Video - I really like this idea. This video is from these guys.

Look at this twig!  It must have snapped off from higher up, probably when a bird tried to land on it, fell down, and somehow managed to hook itself on another branch before it hit the ground.  That’s pretty impressive, even for a twig.
