Welcome to another eclectic collection of physics-ish links. This week on Nautilus, I wrote about how that Quirky Muon Just Might Spur a Physics Breakthrough—Again.
I also hosted a great conversation with JPL planetary scientist Kevin Hand on Virtually Speaking Science in Second Life. Kevin was the science consultant for the awesome new film Europa Report, and he dished on the behind-the-scenes details of how the filmmakers worked real science into their fiction. We also chatted about his own research recreating the conditions on Europa in the lab (“Europa in a can”), and his experience joining director James Cameron on the latter’s dive to the bottom of the Mariana Trench.
Incidentally, Kevin was featured in Cameron’s IMAX film several years ago, Into the Deep, and also consulted on Avatar. Plus, he founded his own charity to bring science education to kids in Kenya. So, you know, he’s pretty damn awesome. You can listen to the taped podcast on Blog Talk Radio here.
The geekerati have wasted no time weighing in on the science aspects of the film. And NPR’s Robert Krulwich is kinda bummed to find out that the “top predator” on Europa is likely to be a “fearsome creature with the mass of one gram.” Or 3/100ths of an ounce.
Elysium also earned high marks on the bringing real-world science to science fiction scale. This film by the same dude who made District 9 contains quite a bit of perfectly plausible technology. And Kyle Hill explained How Elysium is a Carnival Ride, and Why its Atmosphere is a Bucket of Water.
Also in Nautilus this week: In some fields of science, finding things by accident happens all the time. Particle physics is not one of them. Also: Chasing Coincidences with Statistics: Why it’s hard to recognize the unlikely.
This week on Quanta: In Natural Networks, there is Strength in Loops.”Loop architectures, like redundant computer networks or electrical grids, make structures resistant to damage. “ Also, George Hart is back with an amazing new video: Making Music With a Möbius Strip, the surprising connection between topology and musical chords.
This was also the week that Elon Musk — of Tesla and Space X fame — announced he’d be revealing his schemes for something called a Hyperloop: a super-fast commuter train using pneumatic tubes that would be able to go from San Francisco to Los Angeles in a breathtaking 35 minutes. We like Musk; so does Physics Buzz, in part because he says cool stuff like, “I think of the future as branching probability streams.” Also? Rockets, baby!
But it didn’t take long for the skeptics to weigh in. Technology Review warned that we should Expect a Long Wait for Musk’s Hyperloop to become a reality, while over at Jalopnik, Stephen Granade outlined the three biggest challenges facing the project. Even The Daily Show’s John Oliver weighed in with his trademark skewering of the hype. In contrast, Slate offered a refreshing counterpoint to all the buzzkills, insisting that the Hyperloop is not as crazy as it seems, along with Scientific American: We Could Make Elon Musk’s Hyperloop Real. That’s the spirit! Dare to dream!
It’s all very steampunk, as retro as it is futuristic, in Jen-Luc’s humble opinion. Several people pointed out that the notion of a pneumatic tube transport system isn’t all that new. I blogged about Alfred Beach’s plans for such a system in New York City back in 2011. Bloomberg News was more belligerent: New York Had a Hyperloop First, Elon Musk. (Subtext: Take that, Mr. Genius Billionaire Guy! Pbbt!) The Guardian reminded us that a Hyperloop between London and Edinburgh was proposed in 1825. Curbed LA pointed out that back in 1909 there was a plan for a superfast elevated transit between Los Angeles and San Francisco.
Related: “The Cat in the Canister.” The Atlantic remembers that time people sent a cat through the mail using pneumatic tubes. “As a general rule, it seems, humans will always find ways to join cats and series of tubes.”
So Is the Internet Really Just Cats? It involves toxoplasmosis, metonymy and the transitive property of congruence:
With all the Hyperloop hype, maybe you didn’t notice that the Perseids Bombarded Earth with Comet Dust this week. There were some impressive photographs making the rounds, as well as this incredible footage showing a Perseid meteor exploding. The Guardian‘s Gavin Extence says that science has not diminished the awe and primordial pleasure human beings feel when looking up into the night sky.
