If this week's link fest has a theme, it might just be teleportation. I wrote about The Trouble With Teleportation for Nautilus this week, a.k.a., why the pig lizard in Galaxy Quest met with an icky end. The same issue featured a cool science fiction short story in, which one woman faces a tough choice when teleportation goes awry. Back in the real world, a new paper finds that human teleportation is far more impractical than we thought. Specifically, "Physics students from the University of Leicester have calculated the time and energy required to beam a complete person from the Earth’s surface to a location in space. Their results were discouraging, to say the least."
Another recurring theme: Time. Is there a "timeless" zone in the universe? Sean Carroll took your light-speed questions. The short answer? No. Related: Buzzfeed offers video proof That You Have Absolutely No Concept Of Time. Also: The Time Traveler's Burden (Abstruse Goose on why time machines are great -- if you're a white guy).
Then there is "Time," A 3,099-Panel xkcd Comic. Per Laughing Squid: "The comic, set in the far future, tells the story of two people trying to save their village located in the evaporated basin of the Mediterranean Sea as it fills back up in one massive flood. The full comic can be viewed at Geekwagon." There is also some behind-the-scenes details of the comic's creation at the xkcd blog. And a lovely profile of creator Randal Munroe at Wired.
Cat-turning: the 19th-century scientific cat-dropping craze. No, really, this was totally a thing back then! Related: The Finch and the Pea had an intriguing Caturday science question: "Are cats actually liquids, or amorphous solids?" Jen-Luc Piquant is going with amorphous solids.

Chris Adami comments on a recent post in Technology Review on the emerging revolution in game theory ("The discovery of a winning strategy for Prisoner’s Dilemma is forcing game theorists to rethink their discipline.

Harnessing Physics in Grand Spaces to Make Music. "[T]he Earth Harp, so named for its inaugural performance when it spanned a mountain valley, is not just a musical accomplishment but a great feat of engineering as well. In a phone interview last month, William Close, the inventor of the Earth Harp talked about what it takes to make beautiful music with a massive physics machine."

Five Animated Gifs of n-body Orbits. Robert Vanderbei of Princeton University has a minimizing code he uses to minimize the light coming into a telescope from stars — "to better see if there are more-softly lit planets traveling in their wakes" -- but it's also useful for modeling the orbits of N-body systems.

Over at Wired, Sean Carroll and Dave Goldberg discuss why scientists should talk to public. Okay, I'm not crazy about the headline, which sets up a bit of a false dichotomy between "cool" scientists and "nerdy" scientists. We need both the loveable nerds on The Big Bang Theory plus colorful characters like Tony Stark, and everything in between, to help folks appreciate the diversity in science. But it's a great conversation and well worth a read.
