I’m glad to have never lived in such places that are only accessible by car. Just cities and 'burbs built up before the phenomenon of encapsulated residential developments became dominant. I always walked (or more often biked) to school as a kid and so did my kids (except for K, of course)
I wonder what sort of effect that has on the psyche. Seems like a recipe for people predisposed to xenophobia.

Weekend #Plankton Factoid 🦠🦐
When most people think about algal blooms, they envision bright green water. However, blooms can also be dark red, invoking the colour of blood. A number of groups can generate red pigment blooms including flagellates like red-tide species Karenia brevis and Heterosigma akashiwo, Alexandrium spp. (Shellfish poisoning), the green algae Botryococcus braunii turning…

Uncovering the Fourier Structure of Wavefunctions in Semiconductors
Symmetry dictates the physical properties of materials. The symmetry of the Bravais lattice defines the set of points, lines, and planes over which sets of planewaves are degenerate, upon which atomic symmetry determines the interaction potentials which may lift such degeneracies. This results in wavefunctions which are single planewaves throughout the BZ, except in the vicinity of the removed degeneracies. As optical transitions between any two planewaves are forbidden, only regions of the Bri…

Coherence and Dimensionality Witnesses for Fractional OAM Modes
We characterize sets of fractional orbital angular momentum (OAM) modes of a light beam using unitary-invariant properties encoded by two-mode overlaps. Using basis-independent coherence and dimension witnesses, we experimentally certify, on a triple of fractional modes, both the presence of coherence and that the states necessarily span a space of dimension 3. We propose and implement a practical, fast experimental method to extract two-mode overlaps requiring only a single intensity image per…

Quantum Dial for High-Harmonic Generation
High-harmonic generation (HHG) is a highly nonlinear optical process that typically requires an intense laser to trigger emissions at integer multiples of the driving field frequency. Since HHG is commonly used as a spectroscopic tool to probe material properties, it becomes impossible to extract information about a material without introducing distortions caused by the strong driving field. Recent advances in bright squeezed vacuum sources have allowed HHG to be driven by purely quantum fields…

UK — High Court to lawyers: cut the ChatGPT or else
US lawyers have spent the past two years filing briefs full of citations to nonexistent cases — because a chatbot made them up. You’d think these intelligent and educated people would know better t…

On the way to Berlin. I’m really looking forward to the BBQ with all the Berlin Python user groups: #Python

Python in Berlin BBQ @ c-base, Thu, Aug 14, 2025, 7:00 PM | Meetup
Normally we announce our talks here, but this time we are taking a short summer break and therefore invite you to a barbecue at the Spree. The BBQ is for all Berlin Python

History doesn’t repeat itself, but it often rhymes. IG Farben initially wasn’t keen on working with the Nazis, but it just made business sense to adapt to the new political environment ¯\_(ツ)_/¯
