Fibonacci you crazy bastard….

As seen in the solar system (by no ridiculous coincidence), Earth orbits the Sun 8 times in the same period that Venus orbits the Sun 13 times! Drawing a line between Earth & Venus every week results in a spectacular FIVE side symmetry!!

Lets bring up those Fibonacci numbers again: 1, 1, 2, 3, 5, 8, 13, 21, 34..

So if we imagine planets with Fibonacci orbits, do they create Fibonacci symmetries?!

You bet!! Depicted here is a:

  • 2 sided symmetry (5 orbits x 3 orbits)
  • 3 sided symmetry (8 orbits x 5 orbits)
  • 5 sided symmetry (13 orbits x 8 orbits) - like Earth & Venus
  • 8 sided symmetry (21 orbits x 13 orbits)

I wonder if relationships like this exist somewhere in the universe….

Cyanuric triazide or 2,4,6-triazido-1,3,5-triazine is white crystalline solid when pure and is an organic primary explosive with a detonation velocity of about 7,300 m·s-1. More than enough to remove a few fingers, so don’t even think about making it.

It is a quite interesting compound, since it only contains carbon and nitrogen, 3 carbon and 12 nitrogen in each molecule and 9 of these are in 3 azido groups. The compound is highly shock sensitive, it explodes while grind in a mortar. It has a sharp melting point a bit under 100 °C but it explodes upon heating above 200 °C giving nitrogen and elemental carbon as graphite and maybe some diamonds.

Since this compound is a highly sensitive energetic material I would recommend to do not try it out how this works. On the picture and the gif approx. 40-50 mg (0,04-0,05 g) cyanuric triazide was ignited. Even this small amount could be enough to cause serious damage, injury. 

Anyone want to read short reviews from energetic materials?

Cloud Chamber

In this image you can see a ‘thoriated-tungsten welding rod’ emitting alpha radiation inside a ’r’. A cloud chamber is a simple particle detector which creates a cold atmosphere of super-saturated alcohol vapour. As a particle is emitted from the rod, it collides with the vapour, causing it to condence back into water droplets, forming these tiny white trails. To find out how to make a cloud chamber, check out the source video: http://youtu.be/orMOkagId04

Introducing the Pudú, a deer as cute as its name. A deer who looks like a baby, and whose babies look like baby babies. 

The pudú (or pudu) is also the smallest species of deer, being only about 40cm tall and 80cm long. They are endangered due to the destruction of their rainforest habitat. 

Pudus were requested by resonanteye, who says “I read that they eat roses and hazelnuts, but that sounds too cute, even for pudus.”

Cheap Graphene Reported From Laser Fired At Plastic

Scientists have come up with a cheap and easy way to make electronics and energy storage components out of the supermaterial graphene.

Researchers can now make the amazingly strong material that is an excellent heat and electricity conductor by firing a laser at cheap plastic sheets. The laser burns patterns into the polyimide polymer, which create microscopic interconnected flakes of the single-atom-thick sheets of bound carbon atoms. 

One of the chemists behind the material says the laser actually creates a hard foam of graphene flakes that remain connected to the plastic from which they are burned. The process can be done at room temperature and pressure, another important manufacturing advance.
