Mind-Melter of the Day
It turns out that if you divide 1 by 998,001 you get all three-digit numbers from 000 to 999 in order.
Except for 998.

Very cool.

Vine Tendrils
Vetches and passion flowers have modified some of their leaves and converted them into tendrils. These grope around in space until they touch the stem of another plant and swiftly coil around it. The tendrils then coil and pull the plant up towards the sunlight.
Oh the beauty of nature…

Tumblr De Stijl.
The identity of a company, specially a web service, depends too much of its website layout. We don’t have to see logos or typography in order to indentify the company, sometimes just we need colors and position. That’s why I merge the website layout with the artistic movement: De stijl.

Tumblr De Stijl.
La identidad de una empresa especialmente de un servicio de internet, depende bastante del layout de su página web. No tenemos que ver logos o letras para identificar la empresa, sólo colores y la posición en la que se encuentran. Por eso quise combinar el layout de páginas web con el movimiento de arte De Stijl.

Gravity bends more than just space. It bends time.
The early results from Gravity Probe B, one of Nasa’s most complicated satellites, confirmed yesterday ‘to a precision of better than 1 per cent’ the assertion Einstein made 90 years ago - that an object such as the Earth does indeed distort the fabric of space and time.
But this - what is referred to as the ‘geodetic’ effect - is only half of the theory. The other, ‘frame-dragging’, stated that as the world spins it drags the fabric of the universe behind it.
[…]
According to Einstein, in the same way that a large ball placed on a elasticated cloth stretches the fabric and causes it to sag, so planets and stars warp space-time. A marble moving along the sagging cloth will be drawn towards the ball, as the Earth is to the Sun, but not fall into it as long as it keeps moving at speed. Gravity, argued Einstein, was not an attractive force between bodies as had been previously thought.
That probably didn’t clarify it any. But there’s more!
When Einstein wrote his general theory of relativity in 1915, he found a new way to describe gravity. It was not a force, as Sir Isaac Newton had supposed, but a consequence of the distortion of space and time, conceived together in his theory as ‘space-time’. Any object distorts the fabric of space-time and the bigger it is, the greater the effect.
Just as a bowling ball placed on a trampoline stretches the fabric and causes it to sag, so planets and stars warp space-time - a phenomenon known as the ‘geodetic effect’. A marble moving along the trampoline will be drawn inexorably towards the ball.
Thus the planets orbiting the Sun are not being pulled by the Sun; they are following the curved space-time deformation caused by the Sun. The reason the planets never fall into the Sun is because of the speed at which they are travelling.
According to the theory, matter and energy distort space-time, curving it around themselves. ‘Frame dragging’ theoretically occurs when the rotation of a large body ‘twists’ nearby space and time. It is this second part of Einstein’s theory that the Nasa mission has yet to corroborate.

Geometry of Light by Alyson Shotz imagines “What would it look like to see light stopped in time”.
About the artist:
Interested in physics, Alyson Shotz uses industrial material, mirrors, stainless steel, to visualize invisible forces like gravity, space and light – the basic elements of our physical world. Materials that proved no less important when it comes to Art. “Questions about what the universe is made of (what is space, what is matter) seem primary to what sculpture, or art, should be about”, says Shotz.
Zachary Abel can’t help himself when it comes to making really cool mathematical sculptures out of everyday objects:
I think about math constantly, and I see and look for math in everything around me. Geometry in particular fascinates me, and I delight in discovering hidden patterns even in the most mundane of objects. By transforming often-overlooked household items into elaborate, mathematical sculptures, I hope to share this sense of excitement, curiosity, and beauty that a mathematical outlook has instilled in me. Maybe I’ll even be able to learn and teach some math along the way.

Sarcastic fringehead (Neoclinus blanchardi)
When two fringeheads have a territorial battle, they wrestle by pressing their distended mouths against each other, as if they were kissing. This allows them to determine which is the larger fish, which establishes dominance.
ok first of all ARE YOU FUCKING KIDDING ME and second of all whats sarcastic about it
dude they also emit the most horrifying sound known to earth, alternia and the outer ring while dueling. one of my favorite animals as of this fall
holy fuck
nature do you have an excuse for this
Ahahaha this is so awesome!
Although, the sounds in the linked video are sound effects, I’m pretty sure, not the noise the fishes make themselves. In this other video from the BBC where the audio gain was turned up high enough to pick out the fishes’ swimming movements, there’s no such sound. And if you were a meter or two away in the water it would seem a lot quieter than even that clip.
Do it:
sqrt(cos(x))*cos(200 x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01,sqrt(9-x^2), -sqrt(9-x^2) from -4.5 to 4.5
