Mars’ largest moon, Phobos, is slowly falling toward the planet, but rather than smash into the surface, it likely will be shredded and the pieces strewn about the planet in a ring like the rings encircling Saturn, Jupiter, Uranus and Neptune.
UC Berkeley postdoctoral fellow Benjamin Black and graduate student Tushar Mittal estimate the cohesiveness of Phobos and conclude that it is insufficient to resist the tidal forces that will pull it apart when it gets closer to Mars.
Mars tugs differently on different parts of Phobos. As Phobos gets closer to the planet, the tugs are enough to actually pull the moon apart, the scientists say. This is because Phobos is highly fractured, with lots of pores and rubble. “Dismembering it is analogous to pulling apart a granola bar”, Black said, “scattering crumbs and chunks everywhere.”

Happy Birthday Carl (1934 - 1996). Your legacy continues to shine.
1. Do science. 2. Advance the human race. 3. Make other people happy.
Imagine a droplet sitting on a rigid surface spontaneously bouncing up and then continuing to bounce higher after each impact, as if it were on a trampoline. It sounds impossible, but it’s not. There are two key features to making such a trampolining droplet–one is a superhydrophobic surface covered in an array of tiny micropillars and the other is very low air pressure. The low-pressure, low-humidity air around the droplet causes it to vaporize. Inside the micropillar array, this vapor can get trapped by viscosity instead of draining away. The result is an overpressurization beneath the droplet that, if it overcomes the drop’s adhesion, will cause it to leap upward. For more, check out the original research paper or the coverage at Chemistry World. (Video credit and submission: T. Schutzius et al.)

A mathematician, a physicist, and an engineer were in a hotel for a convention.
Then, in the middle of the night for no apparent reason, a fire breaks out in the engineer’s wastebasket. The engineer rushes over to the bathroom, empties out the ice bucket, fills it with water and pours it into the trash can, dousing the fire. Satisfied that the problem was solved, the engineer goes back to sleep.
Shortly thereafter, a fire broke out in the physicist’s wastebasket. The physicist rushes to the bathroom, whips out his calculator, frantically does a few computations, pulls out a cup, fills it to a precisely measured level, and rushes back to the wastebasket, pouring the water onto the fire. As the last drop hits the flame, the fire goes out. Satisfied that the problem was solved, the physicist goes back to sleep.
Finally, a fire breaks out in the mathematician’s room. The mathematician rushes to the bathroom, sees the ice bucket, sees a cup, sees the water faucet. Satisfied that the problem could be solved, he goes back to sleep.
-The limits keep getting farther and farther away. Where are they going? Where did they start? Will they ever stop?
-The unit circle tells us to bow before it. All hail the unit circle. All hail.
-You have been scribbling the integral symbol and the summation symbol for so long. You can’t write 3′s or capital S’s normally anymore. It is a reflex, muscle memory.
-Piles of math homework surround you as you become a machine, cranking out more math problems as you hone your skills. You build your own castle out of math homework. It is never-ending.
-Trigonometry rids us of our sins. and cosines. and tangents.
