When Geminid Meteors Rained Down on Earth. If you missed the Geminids meteor shower, the Guardian was among the media outlets that captured the event in pictures. "Sky-watchers have braved freezing temperatures to enjoy one of the year’s most spectacular meteor showers. Clear skies, which sent the thermometer plunging, ensured a good view of the Geminid meteor shower."

The mystery of that magnetic train. "It is billed as the “world’s simplest electric train,” and it is almost certainly the case. Using only a battery, some strong magnets and some (bare) coiled copper wire, one can make the “train” travel numerous circuits through the copper “track,” until the battery is completely drained."

From Plato's Cave to the Holographic Principle. "[T]he holographic principle says that the information contained within a volume can be represented as a hologram of the surface. Notice that this does not imply, in any way, that what unfolds within the room is an illusion, or that the information encoded on the walls is in some way more fundamental than that which fills the room - the statement is simply that the two descriptions are equivalent."

Black hole power in a lightning bolt. "Large commercial planes are equipped to route the electrical current from a lightning strike so that it avoids sensitive electronics, and most passengers may not even realize that a plane has been struck when it does occur. However, the electrical current and loud clap of thunder are not all that is produced by a bolt of lightning. It's only within the past 20 years that research has confirmed that lightning also emits x-rays and gamma-rays."

Scientists Are Not That Smart. Chad Orzel, writing in New York Magazine: "While the idea that scientists are uniquely smart and capable is flattering to the vanity of nerds like me, it’s a compliment with an edge. There’s a distracting effect to being called “really smart” in this sense — it sets scientists off as people who think in a way that’s qualitatively different from “normal” people."

“If it’s in a word or it’s in a book, you can’t get rid of The Babadook.” One of the best films Jen-Luc Piquant saw this year was the indie fright flick, The Babadook, whereby a mysteriously morbid pop-up book ushers in a monster that terrorizes a widow and her young son. That's one level, at least; the film is deliciously complex. Thanks to a crowd-funding campaign, an actual pop-up book will soon be available. And now the studio has issued a video e-card, How the Dook Stole Christmas, to haunt your holiday dreams. Per Nerdist: "Much like The Grinch and Jack Skellington before him, Mister Babadook decided he was going to get in on the holiday action this year. He knows Dasher and Dancer and Prancer and Vixen, Comet and Cupid and Donner and Blitzen, and as you’ll soon recall, Mister Babadook made Santa take a big, nasty fall…"
