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

A Levitating Bluetooth Speaker

"The fact that it levitates is an insanely cool feature, but it’s actually for a practical reason: “360° sound projection reduces sound wave absorption into surfaces by levitating above the subwoofer charging station.” In layman’s terms: It makes music sound better."

Neil deGrasse Tyson, on being asked what would happen if the Earth suddenly stopped spinning.

Sidenote: This wonderful physics funfact is also why you should keep your car clean. A tissue box flying at 85 MPH after your car has suddenly stopped due to a car accident can kill you.

A Rose of Jericho three hours after being watered having nearly returned to is previous, alive, state!

The Rose of Jericho(Anastatica hierochuntica) is a species of resurrection plant. These plants are characterized by their ability to use Poikilohydric mechanisms which enable them to survive extreme dehydration for years at a time.

Soft Robotics!  Just in case, you know, you need to pick up some prickly pufferfish.

The miniaturization of robotics that can do this kind of thing is fantastic, especially for people whom have disabilities. Carry on technology, :D

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.

This octopus blends in perfectly with the coral, changing the color and texture of its skin better than Peeta in the Hunger Games. This impressive skill helps it escape predators like barracuda (or unsuspecting humans).

The Future Is Here, And It's Handing Out Jetpacks

Shut it down, everyone. Future accomplished. We can all go home now.

That actual, real, not-at-all-computer-animated shot of two jetpacked individuals flying in formation was shot in Dubai. You’ve got to check out the video.

Popcorn: a matter of thermodynamics Inside, a kernel of corn is soft because it contains the endosperm, which is made of starch and water, whereas the outer shell of the corn is very hard and, while it’s cooking, behaves like a pressure cooker. The heat, in fact, transforms a part of the water in hot steam, which increases the pressure between the kernel’s walls and dissolves the starch, turning it into a sticky jelly that is mixed with the remaining water. When the pressure inside the grain reaches more or less 9 atm (in a pressure cooker you get less than 2 atm), the outer shell explodes and all the water evaporates instantly, thus cooling the gluey starch which solidifies in the typical white foam.

Just keep swimming, little one.

This wavy sheet of nothingness is actually a baby moray eel. 

Morays start out life as an extremely thin, nearly-transparent larva called a leptocephalus, which literally means ‘small-headed’. They are adorably pathetic, really.

The whole point of the leptocephalus is to go places. Adult morays are generally poor swimmers, so they spend most of their time bumming around and being adorable, and they rarely stray far from home. But as leptocephali, young morays take to the high seas, allowing the currents to carry their frail and fragile bodies to distant lands reefs. 

Over generations, this childhood wanderlust has allowed morays to disperse across most of the Pacific, while maintaining close population relatedness over such great distances.
