Turns out we can do better than just copying nature's solutions for other organisms.

If you were upset at the news that Spider-Man is an impossible dream, don’t despair. A set of gecko gloves created by a Stanford researcher make the ability possible once more.

We better come up with a name for the new planet soon.  Because calling it "Planet X" is just asking for trouble!

In their latest look at weird comic book ads, CSBG examines all the reasons why a kid would want an inflatable live size doll...like burglar deterrent!

In this dramatization of transcripts from a legal deposition, a so-called “expert witness” fails to perform middle school math.

Except that it uses fans to provide thrust, pushing it up and against the wall. You know, like a gecko!

Not even walls can stop Disney’s and ETH Zurich’s new four-wheeled robot called VertiGo that can quickly transition from rolling on the ground to climbing obstacles like a gecko—and without those sticky feet.

Have we learned Nothing from Futurama?
 
I, for one, welcome our new robot reindeer overlords: 
Santa Claus is coming to town, pulled by robot reindeer from Boston Dynamics. But is that a promise, or a threat?

I'm developing a new type of mistletoe that is a match for a TOW missile; we should be fine.

Fantastic. Who knew I was mis-pronouncing "legal" all these years?
 
Triumph of observation over theory: Ant Man, who visited the quantum realm, bests Stephen Hawking in quantum chess.

What do you do if you’re Paul Rudd and itching to speak at a Caltech event about quantum mechanics? Challenge your arch-rival, Stephen Hawking, to a game of quantum chess, of course. The very future of the universe might be at stake.

Who knew it related to the Measurement Problem?
"When two things are happening simultaneously in quantum physics it's what’s called the Super Position and when the Observer finally observes the outcome that's called the 'Collapsing of the Super Position'" said director Bryan Singer about the ending of X-Men: Days of Future Past, "which is what happened when Wolverine woke up."

Bryan Singer Weighs in on "X-Men's" Timeline: "Anything Can Happen" - The "X-Men: Apocalypse" director discussed the quantum physics of time travel and how he plays "with time's immutability and the prequel concept."

In an oral exam we once asked a graduate student to calculate this. He determined that you'd need a mass of anti-matter roughly 2 km in diameter in order to destroy Alderaan. 

http://sploid.gizmodo.com/how-much-power-does-it-take-to-actually-blow-up-a-plane-1751532484
Like, a lot of power. Scott Manley delves into the science of the planet destroying business and came up with the numbers that it would take to destroy a planet in Star Wars. To destroy an Earth-like planet which was like Alderaan, you’d need three trillion trillion trillion Joules of energy. There are five billion Joules of energy in a lightning bolt so yeah, you’d need a lot more energy.

Well, it is in a galaxy far, far away, so maybe that galaxy has more anti-matter laying around?

Yesterday I saw an amazing film, that was funny, entertaining and had me leaving the theater really p.o.-ed. (No, not THE FORCE AWAKENS). I saw THE BIG SHORT, and so should you. Very clever techniques to explain complex financial concepts, a brilliant cast and an engaging story. When I got home, I checked my garage to make sure I was set with pitchforks and torches.

Some Fluid Mechanics to start the last week of 2015.  Hope your instabilities are as photogenic!

http://gizmodo.com/theres-some-complex-physics-in-these-photos-of-ink-fall-1749529870
Spherical Rayleigh-Taylor Instabilities, to be exact. That’s what happens when two fluids of different densities collide under the force of gravity. The pattern can be seen in everything from the mushroom clouds of nuclear explosions to cosmic supernovae. But as science photographer Linden Gledhill demonstrates, you can also recreate the fluid dynamics phenomenon at home, using nothing but ink, water, and a good camera.

Even worse when they don't use their words, and have to act out their dreams!
 
Annual holiday reminder: If you don't like it when people tell you long stories about their weird dreams DON'T GO SEE THE NUTCRACKER.
