How many of the physicists/physics students here know the Goos-Hรคnchen effect?

Still writing Visitor patterns and manual tree recursion in Java?

Part 4 of Functional Optics for Modern Java shows how the Focus DSL turns this into fluent, composable paths:

.departments().each().employees().each().salary()
No reconstruction boilerplate. Just declare what you want.

We build a complete expression optimiser using the Focus DSL.

Having gone through the batch, it seems that, (as the Smiths never sang): "Some Prints are Tighter than Others"

I will leave the model as it is and folks can make their own accommodation one way or another.

Oakee doakee... Got the prints back. Sphere retention is a bit too tight with these dimensions. It takes significant force to engage sphere. Will adjust octagon dimensions for greater accommodation.

Note: Material is black photopolymer resin. SLA process. No sanding.

(Can you tell I'm nervous about videoing this?)

This #WiOWednesday, we highlight Arianna Bresci's dedication to math, physics, & #optics in her work as a postdoc associate at MIT. She strives to emphasize the creativity, collaboration, and impact within the STEM community. ๐ŸŒฑ๐Ÿ’ก Learn more in the 2026 #WomenInOptics notebook! https://bit.ly/3LqTDXm

Modernity likes to paint Nietzsche as a nutjob responsible for the rise of the Nazis, but he's always just been the messenger. Today, his message applies to Trump and America, who Carney out.

Are there any off-axis catadioptric mirror lenses that I can buy for my camera?

Seowon & Jonathan worked together in the Fattahi group on observing non-Hermitian edge modes.

Seowon is from Korea & studied at @FAU. Her previous work as embedded programmer for optical systems sparked her interest for optical systems.

Jonathan is a #physics student at FAU & #research assistant at MPL. He is driven by curiosity to understand the unknown.

Experimenting with sphere retention structures which can be more reliably manufactured using FDM/SLA processes.
It's "The Octagons" this time!

โœจ Ever wonder why fresh snow sparkles in sunlight? Individual crystal facets act as tiny mirrors. When light hits at just the right angle, these flat surfaces create specular reflection: brilliant pinpoints distinct from snow's overall whiteness. Old snow loses this sparkle as crystals round through sintering, trading mirrors for curves.

๐ŸŒ™ The full Moon appears about 40% brighter than geometry predicts due to the opposition surge, where regolith's microscopic particles hide their own shadows and can even produce coherent backscatter when Sun, Earth, and Moon nearly align.

โœจ This hair-trigger optical effect reveals how alien dust transforms moonlight itself.

A #genocide of attrition in a world of #optics...

I don't think we were ready for this kind of innovation, but if anyone could innovate pure, abject and destructive #authoritarianism, it would be the #Zionist

A slow, systemic genocide, where every necessary resource is being bottlenecked - or even completely choked - by way of #Israeli "border control".
