OK, and now a puzzle/quiz for the #symmetry (point group) oriented people. What is the label you would associate to an object we are seeing, somewhere in the picture?

A clarification (?) for the non-magnetochemists: it's a popular arrangement for the first layer of atoms around the magnetic ion in lanthanide-based single ion magnets (LnSIMs). Popular because it was present in the first family of LnSIMs, and also because it's rather stable, chemically, so it's common.

Let’s take a look at the next installment from my visit to #SURF last week. After arriving at the Ross Campus, we walked from the end of the tram line to the first of the VERY large DUNE caverns. DUNE is the Deep Underground Neutrino Experiment and will consist of huge neutrino detectors comprised from 17,000 tons of liquid argon. 800,000 tons of rock has been excavated to make the caverns.

THEY. ARE. HUGE.

Each is over 100m long.

Why does nature love spirals? Because Kenner's ad campaign, "Your eyes won't believe what your hands have done" really captured Nature's imagination. And it was bored on a rainy Saturday, and driving its Mother nuts

A first look at the #underground visit to the Sanford Underground Research Facility. We arrived early in the morning to gear up and then catch a 07:30 cage (elevator) to the 4850ft level. We then rode a tram on a rail line from the Yates Shaft and the “Davis Campus” of the lab over to the “Ross Campus”, where the DUNE (Deep Underground Neutrino Experiment) will be constructed.

"A curated selection of key pages from the notebooks will be launched online for the first time on the Royal Institution website on 24 March, to mark 200 years since Faraday founded the annual Royal Institution Christmas lectures."

The Guardian · Unearthed notebooks shed light on Victorian genius who inspired EinsteinBy Donna Ferguson

Amazing!

How a young uneducated Michael Faraday became a world changing scientist and strove to help others be inspired the way that he had been himself.

And his detailed, intricately illustrated notebooks are going online shortly.

The Guardian · Unearthed notebooks shed light on Victorian genius who inspired EinsteinBy Donna Ferguson

This stunning image from the James Webb Space Telescope shows 50,000 sources of near-infrared light. The galaxies of Pandora’s Cluster act as a natural gravitational lens, magnifying distant galaxies from the early Universe. Some lensed sources, red in color and distorted, provide a glimpse into the past, stretching the very fabric of spacetime. A foreground star shows Webb’s unique diffraction spikes.

Wow, this sounds kind of exciting.

Steps towards creating a Thorium Nuclear Clock and using it to measure the Fine Structure Constant carefully enough to see if it is changing (there has been some evidence that it might not be truly constant). Which is a scary wild thought, actually.

I feel like there's a Doctor Who premise in here somewhere!

Here are some shots of last night's lunar eclipse captured by the Allan I Carswell Observatory crew!
Missed the lunar eclipse? Well you're in luck! We livestreamed it and you can watch here:

hey maths and physics nerds

Unlikely to ever be directly useful in practice, partly because the grating spacing and alignment is so touchy and the light modulator's resolution and speed would need to increase, partly because other methods are so effective.

Still very cool for the nerds!

A graph of a continuous real-valued function that has peaks around prime integers (minus 50) with an overall vaguely Gaussian envelope so peaks around 50 (minus 50) are tallest.
