Holy cow, there was a lot of physics-related news this week! Don’t you people realize it’s a holiday? Speaking of which, the Fourth of July holiday celebrating U.S. independence spawned the usual round of sciency angles.
Popular Science offers a festive science lesson to mark the 4th of July: What would happen if you shot off fireworks in space? Need a science of fireworks refresher? Check out this awesome graphic that’s chock-full of ‘BANG!’ and ‘OOOOW.’ For some celestial pyrotechnics, a comet the size of a mountain, called ISON, chose this week to put on a fireworks show in space.
Over at Rosetta Stones, Dana Hunter explains Why Fireworks Depend on Geology. For a historical twist: Do Fireworks Resemble the True Sights and Sounds of the U.S.’s Key Historical Battles? Related: A look back at the role weather played in the Battle of Gettysburg, which marked its 150th anniversary this week.
National Geographic offers some handy tips for photographing fireworks.
Meanwhile, by refocusing during long exposure, photographer David Ian Johnson takes the most unusual fireworks photos you’ve ever seen (h/t: Steve Silberman). As Johnson told This Is Colossal: “Each shot was about a second long, sometimes two. I’d start out of focus, and when I heard the explosion I would quickly refocus, so the little stems on these deep sea creature lookalikes would grow into a fine point.”
Grilling Over Charcoal Is Objectively, Scientifically Better Than Grilling Over Gas. Science says so! Because flavor and taste aren’t the same thing.
Via io9, here’s a list of Independence Days from across the Multiverse: “Where there’s society, there’s a foundation story.”
Walt Whitman Reads “America”: Only Surviving Recording of Poet’s Voice: 36 seconds on a rare wax-cylinder capsule. Bonus: Listen to Aaron Copeland’s “Fanfare for the Common Man.” [h/t: Karen James] And NPR explores why the bells and cannons of Tchaikovsky’s 1812 Overture plays every July 4th.
A biophysicist shares some of her insights on the science of an apple pie. The Guardian‘s Alex Bellos offers a Geometry bake-off: sconic sections, toast tangrams and the Möbius bagel. Related: How does competitive eating represent us as Americans?
Apparently Cosmic ‘Booze’ has been created in a sort of quantum brewery. The Mythbusters ask: Wine Not? “There’s no better way to solve a wine myth, than to head to a winery.” And Parks and Recreation pokes good-natured fun at the phenomenon of molecular mixology: “This is the wrong way to consume alcohol.”
Debating Dark Matters: Technology Review‘s Physics arXiv blog ruffled a few physicists’ feathers this week with this post, asserting that “Astrophysicists believe that our galaxy must be filled with more dark matter than ordinary matter. Now astronomers say they can find no evidence of dark matter’s gravitational influence on the planets. What gives?” No sooner had I tweeted the link, when an irritated Katie Mack (a.k.a. AstroKatie), who knows a little something about dark matter (it’s her field), responded with a series of Tweets. A sampling: (1) “This @TechReview post is INCREDIBLY misleading. Result not at all in conflict w #DarkMatter theory.” (2) “It’s a common misconception that #DarkMatter should be important in our Solar System. There’s a lot in Galaxy in total, but little nearby.” (3) “There’s no mystery, astronomers are not confused, & this result is totally unsurprising. Bad job, @techreview.” Eventually Ethan Siegel of Starts With A Bang brought the official bloggy smackdown with an in-depth look at the paper in question. Good times!
This week also marked the one-year anniversary of the discovery of the Boson We Call Higgs. Brian Greene wrote a nice reflective piece in the Smithsonian: “Before the particle was discovered, it had to be imagined.” For explain-y Higgsy goodness, check out this cool Tumblr, Understanding the Higgs Boson, or the links in this post by theoretical physicist Matt Strassler. As for current Higgs-related news, Strassler gives the lowdown on rumors of a second Higgs particle, concluding the answer is — Very Probably Not. “You see a bump in CMS data. You don’t see a bump in the ATLAS data.”
The Mathematics of Home Run Records. “Babe Ruth x Hank Aaron = the product of the first seven primes multiplied in succession.”

The late Sci-Fi Author Iain M. Banks Gets an Asteroid Named after Him (“and will be referred to as such for as long as Earth Culture may endure”). Seriously, how cool is that?
Meanwhile, The Planet Formerly Known as Pluto’s Two Newly Discovered Moons Get Hellish Names. William Shatner mourned on Twitter: “They didn’t name the moon Vulcan. I’m sad.” But it’s in keeping with the longstanding naming tradition for Pluto’s moons. Per Phil Plait:
All the moons are named after characters associated with the Roman god of Pluto, god of the underworld Hades. Charon was the riverboat driver who brought the dead to Hades. Nix is named after Nyx, the goddess of the night, sometimes depicted as a mist that comes from the underworld. … Hydra was a nine-headed dragon that lived in a cave near the entrance to the underworld (and the nine heads were a sly reference to Pluto being the ninth planet). Kerberos is the name of the three-headed dog guarding the underworld, usually spelled Cerberus…. Styx was the river separating the underworld from the realm of mortals and also a 1970s rock band. That last bit may be coincidence.

Women do better on math tests when they fake their names. “[U]sing another person’s name is a kind of hack to overrule the self-reputational threat — the fear some women have of doing poorly when they’re concerned that it’ll be taken as proof of a stereotype. But removing this pressure seems to alleviate the fear and the distraction.”

The Flap over Roof Flaps: they help keep cars on the ground because of Bernoulli’s law. “A wing develops lift because the air flowing under the wing moves slower than the air going over the wing. That creates more pressure under the wing than over the wing, which generates a net force upward. That’s a good thing for an airplane. Not so good for a race car.”
Here are two takes on new research demonstrating how atomic bomb blasts from the Cold War could help put ivory poachers in jail, one from the Los Angeles Times, and the other from Ed Yong at Not Exactly Rocket Science.

Finally, for your listening pleasure, via Laughing Squid: “Kim Boekbinder, also known as The Impossible Girl, has released the music video for “Stellar Alchemist” from her space album The Sky is Calling. The song is about the process of fusion that takes place in the heart of stars, and even integrates the actual sound of star HR 3831.” She also has a whimsically playful tarot-inspired video for her tune “Gypsy,” if stellar physics isn’t your thing.
