Humanoid Robots: The Scaling Challenge
​It takes more than building a humanoid robot to build a humanoid robot product.

Good day to be the CEO of beehiiv.

Crazy scientific instrument idea with probably limited practical use: inverse spectrometer.
Broadband light source (halogen lamp etc), collimating lens, slit, prism, then transmissive LCD to provide selective attenuation at each spectral bin and some kind of focusing optics to combine the resulting light back into a single beam.
Do a bit of calibration for system losses and the light source spectrim and you end up with a device where you can load in a spectrum of an arbitrary lig…

Keine Redaktion, kaum Kontrolle, dafür prozentuale Beteiligung an allem – auch an Propaganda. Romantische Erzählung vom freien Netz trifft auf die Realität: Wer alles zulässt, verkauft auch das, was der Demokratie schadet.

High-resolution luminescence spectroscopy of CaWO$_4$:Ho$^{3+}$: Sensitive detection of internal strains, temperature, and magnetic field
We carried out high-resolution (0.02 cm-1) measurements of the photoluminescence (PL) spectra of CaWO4:Ho3+, including in magnetic field, and performed spectra modeling. Well-resolved hyperfine structure was observed in the luminescence spectra of CaWO4:Ho3+ for the first time. Energies of several crystal-field levels were specified, g-factors were determined. Variations of a magnetic field as small as several tenths of mT can be detected from the PL spectra. We show that the PL spectra are muc…

I have been trialling Substack as a supplement to my blog. Substack has a large community of people interested in local and social history, so it's a good fit for me. I'm not planning to stop blogging, and some posts may appear in both places, but it allows me scope to write on a wider range of topics. https://
