Some (many?) states have closed Republican primaries. In the states you can only participate if you are a registered republican.
Thanks for explaining!
Also, IMO the “why isn’t this working, why did I do this” stage is a right of passage and sign of progress in any new activity! Keep on trucking!
Where is the burned on filament? Is it that grey-ish blob between the box with the little curly q at the bottom and the heatsink looking piece?
My apologies in advance for what is probably a naive question. I don’t have a printer, I’m just “print curious” at this stage, and want to understand more.
Google Lens showed this as Stadtbad Steglitz.

It’s nice to get some recognition, thank you.
From the image caption:
Biphoton state holographic reconstruction. Image reconstruction. a, Coincidence image of interference between a reference SPDC state and a state obtained by a pump beam with the shape of a Ying and Yang symbol (shown in the inset). The inset scale is the same as in the main plot. b, Reconstructed amplitude and phase structure of the image imprinted on the unknown pump. Credit: Nature Photonics (2023).

Edit: Sounds like this is actually observed, but I don’t believe this is something one can “see”. The images are constructed from the difference between two states: one a reference state and the other being the state as captured by a pump. This isn’t all different, as I understand, than capturing light in film or a photo sensor: the reference state being the film/sensor detecting no light and the second state being when it exposed to light.
Commenting so I can find and watch this later!! Thanks for sharing!
I’d upvote you twice if I could!
