Welcome to 2014! Just when you thought the excitement of the holidays was over: apparently today is Zero G Day! No, you won’t be able to float because of the combined gravity of Jupiter and Pluto. Phil Plait bringeth the smackdown on this pseudoscientific nonsense. “It’s hard for me to overstate just how wrong this claim is. After all, the physics is wrong, the claim about Pluto and Jupiter is wrong, and it’s based on a joke made by an astronomer nearly 40 years ago!”
In honor of the new year, we give you the Physics of Poppin’ Bottles: “just 5 percent of the carbon dioxide is spent propelling the cork.” Related: The fluid dynamics of breaking out the bubbly: “Champagne owes much of its allure to its tiny bubbles.”
There also innumerable year-end listicles, like this one: Dark matter, acoustic lasers, black hole firewalls, and more: APS Physics editors share their Highlights of the Year. And the folks behind the FQXI podcast also reviewed the year in physics with Part I, Part II and Part III — because there was so much physics goodness last year, they couldn’t fit it into a single episode.
Isaac Asimov Predicts in 1964 What the World Will Look Like Today — in 2014. “Communications will become sight-sound and you will see as well as hear the person you telephone. The screen can be used not only to see the people you call but also for studying documents and photographs and reading passages from books. Synchronous satellites, hovering in space will make it possible for you to direct-dial any spot on earth, including the weather stations in Antarctica.”
Forest snow melts faster than flakes in open fields. “Trees became key players in melting snow in warmer locations.”
An interesting paper appeared on the arXiv this week, supposedly constituting “the most sensitive and comprehensive search yet for time travel from the future” — a search of social media, like Twitter and Facebook. Sadly, the search failed to turn up evidence of time travelers: “Given practical verifiability concerns, only time travelers from the future were investigated. No time travelers were discovered.” But perhaps there is good reason for that. “Maybe social media doesn’t persist in the far future, so time travellers don’t know how to tweet,” Columbia physicist Brian Greene told The Atlantic.

Mother and Son Blow Bubbles in Freezing Cold and Discover Something Beautiful. Per Twisted Sifter: “After finding a soap bubble recipe online that consisted of dish soap, karo syrup and water; the mother and son braved the elements to see what would happen. … Not only did each bubble freeze with their own unique pattern but they also deflated and collapsed in spectacular fashion.”

What would the Higgs boson look like if you tried to explain what it is and what it does through dance? That’s what Yale physics professor Sarah Demers sought to answer when she collaborated with dancer and choreographer Emily Coates on a Higgs-related video project, thanks to a grant from the New Haven Arts Council. Various particle physicists used different analogies to explain the Higgs mechanism. Then, they were asked to speculate on what kind of dance might convey the same concepts. Check out the resulting video below. (Jen-Luc Piquant hopes they do a follow-up with an actual created dance, performed by Coates and her cohorts — although having the physicists dance along could be pretty fun, too.)
