Physics Week in Review: April 14, 2018

The ADMX experiment is all set to hunt for dark matter particles called axions; the physics of diving peregrine falcons; and why fastballs are unlikely to get any faster in baseball. Read about all that and more in this week’s roundup of physics highlights.

It’s technically not physics, but our sweet one-year-old rescue kitty, Ariel, made her modeling debut at the top of this Inverse article by Rae Paoletta: Why Cats Slow Blink at Humans, According to Science.

This May Be the Experiment That Finally Discovers the Dark Matter Particle. Related: If Tiny Dark Matter Particle called the Axion Exists, The ADMX Experiment Is Now Ready to Find It. Also: Scientists on the Axion Dark Matter Experiment have demonstrated technology that could lead to the discovery of theoretical light dark matter particles called axions.

Mathematicians Explore Mirror Link Between Two Geometric Worlds. Decades after physicists happened upon a stunning mathematical coincidence, researchers are getting close to understanding the link between two seemingly unrelated geometric universes.

Scientists Solve Part Of The Mystery Of How The Columns Of Devils Tower Formed.  Related: Volcanologists use samples from Eyjafjallajökull in Iceland to recreate famous hexagonal columns in laboratory.  I wrote about this phenomenon over ten years ago at Cocktail Party Physics, also in the context of Ireland’s Giant’s Causeway. The geophysics of columnar joints continues to be very cool.

Why symmetry gets really interesting when it is broken. “In both art and science, perfectly symmetrical patterns can be monotonous. Indeed, there’s a sense in which symmetry is the opposite of information.”

The Mesmerizing Animation of Sinusoidal Waves in GIFs by Étienne Jacob. “24-year-old French student Étienne Jacob produces black and white GIFs that transform the curvature found in sinusoidal waves into a multitude of experimental forms. The animated spheres imitate the appearance of mutating microbes or fiery stars, yet tend to remain in a 2D plane.” [Image: Etienne Jacob]

Scientists Create Beautiful Iridescent Material That Could Be Edible. “scientists have created a material [from common cellulose] that, much like soap bubbles and certain insect wings, displays a gorgeous iridescence—a shifting rainbow of colors they can tweak with the same surface.”

Mirror, mirror: The world on the other side of Alice in Wonderland’s looking-glass is not what it seems, but the mirror-like physics of the superconductor-insulator transition operates exactly as expected.

“To settle a debate about when the photograph … was taken, Texas State University astronomer Donald Olson looked to the sky, using astronomical hints to determine the exact date, time, and location it was shot.”

Prankster George Gamow and Léon Rosenfeld determine the velocity of a heavy object — Wolfgang Pauli — moving through water in a bathing suit.

Psst! An optical version of a whispering gallery (for light instead of sound) boosts solar cells. p

The Body Electric: Batteries are the weak link for wearable and implantable devices. But what if you could harvest energy from the heat, sweat or vibrations of the wearer?

“Pay attention after a rainfall, and you may notice beads of water gathering in the corners of a spider’s web or along the leaves of a cypress tree.” Physics explains why.

Muons for Nuclear Waste Inspection: Muons could be used to check whether spent fuel rods are missing from the casks used to store waste nuclear material.

Invisible London: A near-infrared look at the British capital. “It might look like these pictures are just black and white, but if you look more closely, you can start to see there’s something strange about them… What we’re seeing here is called near-infrared. It isn’t heat. It’s a color just beyond the red end of the rainbow.” (Bonus: See my 2008 blog post about Caltech physicist Tom Prince’s own forays into infrared photography.)
