Recently I came across a new YouTube channel. It’s called Periodic Videos, and what it comes down to is a few professors from the University of Nottingham in the U.K. with a slow motion camera doing super amazing experiments!
Also, professor Poliakoff has super awesome hair!
P.s. You guys should check out Bradys’ other channels as well. He has ones for math, physics and a few more.
What science related channels do you guys like?

Probably The Best Star Wars Photography You’ll Ever See

This is just a tiny sample of Flickr User Avanaut’s work. He takes extremely well composed shots of Star Wars toys (action figure and LEGO) and then composites them into real scenes.

The results are spectacular and you should go and see the others in his Flickr stream.

"Theoretically speaking, everything can be turned into a black hole. Every mass value has an equivalent number called the “schwarzchild radius.” If you would compress that mass to as small as having a radius equal to schwarzchild radius, it will become a black hole. The schwarzchild radius for the Sun is 3km, while for Earth, it is 9mm (meaning that an object would have to get within 3km of the Sun or 9mm of the Earth to be sucked into them…if they were black holes)."

All About Black Holes:

In essence, black holes are the most amazing things in the universe because they represent everything that we know and everything that we don’t know. They stand as the final hurdle into creating a grand theory of everything.

"Meyer’s design has two basic components: a molecule and a nanoparticle. The molecule absorbs sunlight and then kick starts a catalyst to rip electrons away from water. A film of nanoparticles then shuttles the electrons away to make the hydrogen fuel."

Malheureusement, la description est vague sur la possibilite de l’appliquer a grande echelle.

Researchers have built a system that converts the sun’s energy not into electricity but into hydrogen fuel. The system then stores this fuel for later use. http://bit.ly/1m1in2t

J’ai deja vu une animation du meme type, mais celle-ci me parait encore plus complete. Toujours plein de surprise. Pour moi, cette fois-ci, c’est la taille de la Comete de Halle qui m’a le plus surpris… elle est aussi grosse que l’Everest! Aussi, voir les U.S.A. a cote de Mercure met les choses en perspectives. Le minecraft world m’a bien fait rire. Je ne crois pas que mes fils se rendront au bout de la map a la marche 😉

The Scale of the Universe – Interactive
Flash Animation Credit & Copyright: Cary & Michael Huang

What does the universe look like on small scales? On large scales? Humanity is discovering that the universe is a very different place on every proportion that has been explored. For example, so far as we know, every tiny proton is exactly the same, but every huge galaxy is different. On more familiar scales, a small glass table top to a human is a vast plane of strange smoothness to a dust mite — possibly speckled with cell boulders. Not all scale lengths are well explored — what happens to the smallest mist droplets you sneeze, for example, is a topic of active research — and possibly useful to know to help stop the spread of disease. The above interactive flash animation, a modern version of the classic video Powers of Ten, is a new window to many of the known scales of our universe. By moving the scroll bar across the bottom, you can explore a diversity of sizes, while clicking on different items will bring up descriptive information.

"Now, we continue to add energy to this mountain, and as energy increases, the particles have no choice but to climb the mountain. Soon the particles form groups, steadily moving upwards and eventually the particles are at the peak, all together, all very excited. It seems now that our particles are very close to each other, very ordered – but still very energetic Our mountain once again has low entropy, but very, very high energy. Our particles are now occupying negative temperatures."

Is Absolute Zero Absolute?

Right now, as I type this sentence, Earth’s Northern Hemisphere is tilted away from the bright ball of light that is the Sun, and it’s cold here (relatively speaking). Humans have long recorded and measured the temperature of their environment, and for good reason. Keeping constant watch on a thermometer helps us prepare for the potential dangers of cold weather. Take zero degrees Celsius, for instance. At such temperatures, water begins to freeze. In some cases, the pipes that the water runs through malfunction, and then there’s the various life-or-death afflictions that can be brought on by this cold temperature. However, zero degrees Celsius is pretty warm compared to zero degrees on the Fahrenheit scale (after all, water freezes at 32 F).

Yet, neither of these can compare to the temperature known as absolute zero.
