Solar energy that doesn’t block the view

A team of researchers at Michigan State University has developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window. It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a clear surface. And, according to Richard Lunt of MSU’s College of Engineering, the key word is “transparent.”

Bill Nye Fights Back!

"Let’s say that I am, through my actions, doomed, and that I will go to hell. Even if I am going to hell, that still doesn’t mean the Earth is 6,000 years old. The facts just don’t reconcile.” -Bill Nye

For our September 2014 cover story on education, we asked writer Ryan Bradley to follow Bill Nye around before his epic battle with creationist Ken Ham.

The story is as epic as The Science Guy’s right hook, so don’t miss it.

"People who believe they have the power to exercise some measure of control over their lives are healthier, more effective and more successful than those who lack faith in their ability to effect changes in their lives."
Albert Bandura  (via psicologicamenteblog)

I was all set to be snarky about this, but I think Neil did well enough on his own.

*Infomercial voice* with such wondrous hits such as “Baby, you’re starlight”, “You make my heart go supernova (duet with Bill Nye)”, and that super great single, “Stars in your eyes”.

Ever wonder how a Jellyfish “stings”?  Turns out, it’s actually like a Needle.  Check out this awesome graphic that Emily Weddle created from the latest episode of Smarter Every Day.

As you can see in the graphic, a Jellyfish actually stings you with needles.  The process in the photo spans the time of approximately 20 milliseconds. If you watch the video I incorporate timing data so you can perform measurements.  

What’s so cool about this is scientists don’t really understand HOW they nematocyst fire.  They’re pretty confident that they’re triggered by mechancial contact on the outside, of the tentacle… but they’re NOT sure how the stinger “inflates”.  Dr. Seymour thinks it’s too fast to be osmotic.  There’s obviously a channel somehow that opens and creates flow and pressure into the organelle.  I bet it’s some kind of REALLY quick chemical process.

I think we’re going to call graphics like this “Smarter Every Day InfoGifs”.     Emily came up with that name, I can’t take credit for it!  Here’s her webpage.

YOOOOOOOOOOOOOOO

Senegal, Mauritania, Mali, Burkina Faso, Niger, Nigeria, Chad, Sudan, Eritrea, Ethiopia, and Djibouti. Those are the countries. It will be drought-resistant species, mostly acacias. And this is a fucking brilliant idea you have no idea oh my Christ

This will create so many jobs and regenerate so many communities and aaaaaahhhhhhh

it’s already happening, and already having positive effects. this is wonderful, why have i not heard of this before? i’m so happy!

What’s up with all those giant volcanoes on Mars?

Mount Everest is an enormous and awe-inspiring sight, towering 9 kilometres above the Earth’s surface. But if you were to stick it on Mars right next to Olympus Mons, the largest volcano in the solar system, it would look foolishly small—Olympus Mons triples the height of Everest and spans the state of Arizona.

Mars is sprinkled with huge volcanoes, hundreds of kilometres in diameter and dozens of kilometres tall. The largest volcano on Earth, on the other hand, is Mauna Loa in Hawaii, which rises only 4 km above sea level.

So why is Mars blessed with these monsters of the solar system? Why doesn’t Earth have any massive lava-spewing structures?

Geology, my friends.

Earth’s crust is split up into plates that move and collide. Usually, volcanoes are formed at the boundaries where two plates meet, and one subducts below the other and melts in the heat below the surface. This melt rises as magma and causes volcanism.

But in some places on Earth, there are “hot spots” in the middle of plates, where magma rises up from the core-mantle mantle in plumes. When this magma is spewed up onto the surface, it cools and solidifies into rock, and over the years, the rock builds up and up. When plumes open out in the middle of the ocean, the magma builds islands.

image

Plumes are fixed, always pushing magma up to one spot, but the Earth’s plates don’t stop for anything. While the magma rises, the plates move over the hotspot—at a rate of only a few centimetres a year, but still, they move and take the newly-made volcanoes with them. So, gradually, the plates and volcanoes move on, while the plume remains in the same spot, building a whole new volcano on the next bit of the plate. As the plate moves on and on, the plume builds up a whole chain of islands, called island arcs. This is how the Hawaiian Islands were formed.

image

The island-volcanoes never get too big, because the plates keep moving onwards. On Mars, however, the volcanoes are enormous because the magma appears to keep rising, cooling and solidifying in the same place, taking its sweet time to build up colossal mounds of volcanic rock kilometres high.

So far, we’ve seen no volcanic arcs like we do on Earth, and this is generally taken as evidence that Mars has no tectonic plates.

trigonometry-is-my-bitch:

 An Isochrone curve is the curve for which the time taken by an object sliding without friction in uniform gravity to its lowest point is independent of its starting point. The curve is a cycloid, and the time is equal to π times the square root of the radius over the acceleration of gravity.
- A ball set on an Isocrone (or Tautochrone) curve will reach the bottom at the same length of time no matter where you place the ball, so long as there is no impeding friction.

[Gif] - Four balls slide down a cycloid curve from different positions, but they arrive at the bottom at the same time. The blue arrows show the points’ acceleration along the curve. On the top is the time-position diagram.
