How Big is Space?


From The Resonance Project:

It’s a challenge to even perceive how big “big” really is. Hopefully this meme helps you to realize how large our local environment is. The galaxy may seem huge, but its only a speck in Laniakea, our local supercluster of galaxies…

HOW CAN A COPPER PIPE INTERACT WITH A MAGNET?


From memolition.com:

Magnets are not attracted to copper, but incredibly strong magnets interact with copper in a pretty amazing way. If you drop a neodymium magnet down through a copper pipe it’s descent is slowed. The stronger the magnet and the thicker the pipe, the slower the fall. Take a look.

This is an excellent demonstration of Lenz’s law and eddy currents. If you’re not familiar with Lenz’s Law, Wikipedia defines it as: “An induced electromotive force (emf) always gives rise to a current whose magnetic field opposes the original change in magnetic flux”.

I shall propose a theory, which will have any and every mathematician or scientist worth his or her salt wearily shaking their heads, to their detriment, of course…:

I propose that straight lines are antithesis to nature and that what we perceive as such are parts of an enormously long curve, because nature can not abide straight lines. The seeming impossibility of this idea strikes me as being highly plausible! We can only have approximations of straightness (no sexual double entendre intended ;-)) The only straight line that could possibly exist is the one in your outdated imaginations.

However, I seem to contradict myself here(how delightful). Did I not state on a previous occasion that anything we can imagine is, if not true yet, then at least possible. Could there exist something more powerful than my imagination? Wether it be Mother Nature or God perhaps? What a droll and novel notion…

I leave it to the scientists to prove beyond a shadow of a doubt that a straight line does exist in nature or anywhere else, except their imagination. Until then I leave you in the certainty that they’re nonsense(predominantly the straight lines and to a lesser degree the scientist’s imagination).

Astronomers Witness Birth of Milky Way’s Most Massive Star

From http://www.sciencedaily.com/releases/2013/07/130710062240.htm

July 10, 2013 — Scientists have observed in unprecedented detail the birth of a massive star within a dark cloud core about 10,000 light years from Earth.

The team used the new ALMA (Atacama Large Millimetre/submillimetre Array) telescope in Chile — the most powerful radio telescope in the world — to view the stellar womb which, at 500 times the mass of the Sun and many times more luminous, is the largest ever seen in our galaxy.

The researchers say their observations — to be published in the journal Astronomy and Astrophysics — reveal how matter is being dragged into the centre of the huge gaseous cloud by the gravitational pull of the forming star — or stars — along a number of dense threads or filaments.

“The remarkable observations from ALMA allowed us to get the first really in-depth look at what was going on within this cloud,” said lead author Dr Nicolas Peretto, from Cardiff University. “We wanted to see how monster stars form and grow, and we certainly achieved our aim. One of the sources we have found is an absolute giant — the largest protostellar core ever spotted in the Milky Way!

“Even though we already believed that the region was a good candidate for being a massive star-forming cloud, we were not expecting to find such a massive embryonic star at its centre. This cloud is expected to form at least one star 100 times more massive than the Sun and up to a million times brighter. Only about one in 10,000 of all the stars in the Milky Way reach that kind of mass.”

That Fabulous Orion Nebula!


Look at those colours… From Science.Memebase.com

And what about all those stars? There could be little Joes or Janes living anywhere in there!!! Or Glurckles, maybe Strontles?

My neighbour John just remarked that Orion may actually not be a nebula. He’s lying, because it’s been a while since I last cleaned my glasses and if I say it’s a nebula, then we are unanimous about that, dangit!

The Power of Three!


Original Author: Mike Horvath New version by j...

I have been struggling with the notion of an alternate arithmetic for a while now, but once again, I am stumped.

Let me start simple and try to not confuse myself:

One and zero are just conventions, starting from the on/off principle.

There are other ways of looking at nature.

How about the power of three? As in colour(of light) theory: red, green and blue.

Take an even-sided triangle, with the angles being one of these three colours.

You can divide up each side of the triangle in as many parts as you like, but the middle of each side will come out as one of three secondary colors and form a new smaller triangle, and you can repeat this process ad infinitum.

I’m certain that, starting from this premiss, one could create a viable construct for doing calculus with, but I am too thick to see it! Can anybody help?

Dallas scientists have created a new device, which can render objects behind it invisible, using nano carbon tubes to bend light rays.

See the video!

The Obama administration is planning to use this technique to hide the state of the US economy from the eyes of the world! All hail technology!!

Of course, in Europe EU politicians had mastered this technique long ago as the following article shows:
