Und hier ein entsprechender Blog-Beitrag von Barbara Fischer:

Just checked out some truly excellent books from the library to read to my 4-year-old:
Adèle & Simon by Barbara McClintock (things to find), The Marvelous Now by Angela DiTerlizzi and Lorena Alvarez Gómez (rhyming & positive encouragement about mood regulation), and Forts by Katie Venit & Kenard Pak (lovely ode to children's forts).
I had a wonderful reverse-Magritte moment reading Adèle & Simon where Simon loses his drawing of a cat and my kid pointed out one of the actual cats in the image. I said "No, that's a cat, we're looking for a drawing of a cat," before realizing that technically we were looking for a drawing of a drawing of a cat, and the thing my kid pointed to was indeed a drawing of a cat, just not in that category relative to Simon's frame of reference...

Abstract: Production and manipulation of orbital angular momentum (OAM) of coherent soft x-ray beams is demonstrated utilizing consecutive diffractive optics. OAM addition is observed upon passing the beam through consecutive fork gratings. The OAM of the beam was found to be decoupled from its spin angular momentum (SAM). Practical implementation of angular momentum control by consecutive devices in the x-ray regime opens new experimental opportunities, such as direct measurement of OAM beams without resorting to phase sensitive techniques, including holography. OAM analyzers utilizing fork gratings can be used to characterize the beams produced by synchrotron and free electron lasers sources; they can also be used in scattering experiments.

ICE rolls into Los Angeles neighborhoods for raids, parks illegally and rushes in. LA tow truck drivers are rolling up too, towing those SUVs like anyone else. Same streets, same laws, same accountability. (c/o Barbara Sobel)
