Graphing curves was far less colorful before computers.

Let's watch the GOP candidates now as they all get on board with Fiorina's arguments against renewable energies and read this fantastic article that explains the facts about renewables. Ignore the name calling in the second paragraph. The facts presented in the rest of the article are the most damning thing for Fiorina and her party's flagrant misrepresentation regarding what can be done about climate change and the burgeoning renewables industry. 
 
Carly Fiorina shows just how intellectually stunted the GOP is on the #environment

This meme has been in my stream two or three times already so forgive me if you've already seen it but it's just to good. Had to re-post.

The only way we know anything about the forces in play in the natural world is that we observe their effect, measure it, and then give it a name and develop theories about why those measurements are what they are. So, I guess that's why dark matter is so new and elusive is because we weren't able to observe it until we were able to make observations and take measurements on a grand scale and because it doesn't seem to interact with any of the known forces other than gravity. But, If my understanding is correct, gravity isn't a force at all. It's the effect that mass has on the curvature of space time. So dark matter has a small effect on the curvature of space time but effects nothing else and, again if my understanding is correct, we're still having problems making direct observations regarding the curvature of space time.
 
"If dark matter has gravity, why doesn’t it form black holes or other structures?"

If you want to form a structure like a planet, star or black hole, you need a large amount of mass together in one place. The way to bring that mass together, of course, is through the force of gravity, which attracts everything with mass towards one another in this Universe. So why, then, would the greatest source of mass in the Universe — dark matter — be entirely unable to form these structures at all? It has mass, it experiences gravity, and yet there’s no such thing as a dark matter planet, star, or black hole. As it turns out, gravity and mass, by themselves, aren’t enough to do the job.
If dark matter is the most abundant form of mass, and has gravity, where are all the dark matter structures?

Maybe, in our search for E.T. we should look for planets with a great deal of garbage in orbit around them.
 
Blasting Space Junk With A Laser
It’s getting crowded up in space: More than 500,000 pieces of debris orbit the Earth. Most of the orbital debris is man-made objects that no longer serve a purpose (old satellites, rockets, and mission-related debris).

These objects travel at speeds up to 17,500 mph. At this speed, a relatively small piece of debris —even tiny paint flecks— can do some major damage to a satellite or a spacecraft. In fact, a number of space shuttle windows have been replaced because of damage caused by flecks of paint.

Here’s how it would work: EUSO, a new Japanese space telescope, would spot the debris using it’s powerful optics and wide field of view. This telescope could be combined with a high-energy laser system known as CAN.
CAN’s plasma pulse could hit the debris and slow it down — so much so that it falls out of orbit and burns up in the Earth’s atmosphere.

Not 'Alien'. Just very different.
Their genetic code is so strange that researchers think they might be something else altogether.

Of course, they're not actually 'Alien' but the arrangement of the octopus genome is so different from what scientists have learned to expect that the alien moniker might not be that much of an exaggeration. 
 
From the article:

"Hundreds of octopus-specific genes were identified, large numbers of which were found in the nervous system, retina, and suckers" and “With a few notable exceptions, the octopus basically has a normal invertebrate genome that’s just been completely rearranged, like it’s been put into a blender and mixed”.
The octopus genome is similar to those of other invertebrates—but scrambled "like it's been put into a blender and mixed."

Do you have the hands of a piano player?
Here are the type of hands you will need to play the music of these composers ;)
