More words I don't know how to say according to the audiobook producer:

-bona fides
-photometer (I. KNOW!)
-expostulating but I had no trouble with "obfuscatorily" for the record

Yeah, but sometimes my pronunciation of a word isn't an idiolectic variation, it's just fucking wrong. I put two extra syllables in "photometer"! I can be wrong sometimes! It's fine!
Words can have different pronunciation. If someone doesn't like how you say something, it may be classism, or their style guide is different. If they want your voice then they get your vocal style guide.

Truly fantastic.

Keep an eye on that CATRA instrument next. (That's what you call your photometer, with blue and yellow filters, right?)

I started doing QC testing for paint dispersions this year. We read the color strengths and shades on a photometer but the guy who trained me can just eyeball a burnt sienna drawdown against standard and see if it's too blue. I'm trying to learn this skill

Survey of marine #aerosols as seen by lidar and photometer

Interesting comments and finding on what we regularly call "prestine marine conditions" , the vertical structure of background aerosols is a bit more complicated than normally assumed.

#SPHEREx

NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) has turned on its detectors. Initial images from the observatory confirm that all systems are working as expected.

This space probe's mission sounds very cool, but why does NASA have to torture the English language like this?

In order to spell out "sphere" they named it

SPHEREx successfully Launched on March 11th 2025! The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission will provide an all-sky spectral survey. SPHEREx will look at 450+ million galaxies to explore the origins of the universe. 🔭 #astronomy

Gemessen wird dann die Farbintensität dieses Farbstoffs, die nämlich proportional zur Kreatinin-Konzentration im Urin ist, und zwar mit einem klassischen Photometer.
Der Farbumschlag wäre bei einer Blut-Messung aber davon verdeckt, dass Hämoglobin auch rot ist.
Also brauche ich ein anderes Gerät:

New crosswalk locations must undergo a lighting analysis by a PBOT lighting engineer to ensure there is adequate street lighting for pedestrian visibility. Lighting engineers measure current light levels by standing in the street with a photometer (light meter).

This is a really neat result – the #UCSD group are using PUNCH data to drive 3-D models of the entire solar wind flow. Jackson (UCSD Co-I on #PUNCH) invented this field in the early 1980s, using a spinning photometer to make "images" of CMEs. Amazing that we get to work with him today! ☀️🧪🔭🛰️
PUNCH images are now making tomographic models of the solar wind – like a CAT scan of the entire inner solar system! ☀️🧪🔭🛰️

What do millions of galaxies look like?

NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of reionization and Ices Explorer) is an observatory which will conduct an astronomical survey of nearly 450 million galaxies.

Zum #TagDerRaumfahrt wollen wir Euch in Bonn am 29. März 32 Exponate zeigen. Eines davon hat einen besonderen Weg. 🏔️🚡Das Nahinfrarot-Spektrometer und Photometer NISP, die Optik des Euclid-Weltraumteleskops, kommt vom Observatorium auf dem Wendelsteingipfel (1.838 Meter Höhe/Bayerische Alpen) zu uns.
