I just realised, they used my words in the medical certificate/report.

I am not entirely sure how I feel about that.

So if you are wondering how I'll be spending the weekend...

It's obsessing over something that may or may not be important.

You know - the usual.

And...

As it turns out, it matches one of my favourite old t-shirts I randomly picked to wear today.

So, as it IS , I felt I should include it!

The first alt text is for the blind/visually impaired. Second for everyone - but more "me". 

First:

A cartoon graphic depicts a 'versus' battle. At the top, the word 'TIME' is written above an infinity symbol, flanked by two health bars. On the left, under the label 'Schrödinger's Cat,' the cat's health bar is filled with question marks; the cat is illustrated as if simultaneously jumping alertly from an open wooden crate and as a ghostly, white, winged version leaping above the crate. On the right, under the label 'Pavlov's Dog,' a yellow Labrador-like dog drools profusely while gazing up at a large, orange, ringing alarm bell; its health bar is full. The style is humorous and reminiscent of a video game interface.

Second:

In a timeless, whimsically illustrated arena of scientific wit, Schrödinger's Cat—its very state of being a cascade of vibrant question marks on its health bar—explodes from its conceptual wooden prison. It exists as a paradoxical marvel: one moment, a curious orange tabby scrambling to freedom; the next, an ethereal, winged spirit soaring above. Facing this quantum conundrum is Pavlov's Dog, a comically distressed yellow Labrador, a veritable waterfall of drool testifying to the inescapable, ringing summons of a brazen alarm bell. An infinite, humorous duel is captured: the profound mystery of superposition versus the unyielding power of conditioned reflex, forever locked in a playful, visual standoff.

Did you know that statistically speaking:

The number of skulls inside the human body, averaged globally, is > 1?

The Matrix got just one thing wrong... while it was the humans who were responsible, it was the AI itself that boiled the oceans and burnt the skies.

The humans were just not smart enough to stop trying to get it to write their emails (badly)

Some thoughts on the nomenclature of nomenclature

Most of us remember being taught in high school biology that “scientific names” (or “binomial names”) for species are better than “common names” because the latter change all the time and there are multiple names for the same species. For those of us who continue with biology or botany or a related field, there comes a time when one of our favorite species is determined to belong to a different genus or even an entirely different family, and it’s “scientific” name changes, while the common name stays the same.

For me, the first occurrence of this was late lowbush blueberry, which I originally learned as Vaccinium vacillans and which now has a preferred name of Vaccinium pallidum. Amusingly, if you look at the Wikipedia page for this species, you will see half a dozen common names (including both early and late lowbush blueberry) but you will also see more than a dozen different taxonomic classifications!

Now part of this is that species are named in different parts of the world and later determined to be the same species, or plants initially determined to be separate species are later classified as varieties of the same species. Or vice versa!
Over the course of the last couple of decades, genomic studies made possible by modern DNA sequencing have resulted in countless species being renamed, reorganized, and reclassified. So how do we explain this concept to aspiring biologists?

I think the difficulty arises from using the phrase “scientific name”. Outside of biology, we think of a name as a relatively static label that makes it easy to refer to a concept or object. Names are easy to remember and provide a way for multiple people to refer to the same concept. Scientific or binomial names fail to meet many of the criteria for what makes a good name. They are rarely made up of words in common living human languages, they are often long and difficult to remember or pronounce, and they change in unexpected ways.

Binomial “names” are better thought of as addresses. Addresses in a complex classification space, but still addresses. Just as an Internet address helps us locate a resource in Internet space by telling us what protocol to use to connect to a computer at a specific fully qualified domain and the path to the resource we are looking for, with a genus and specific epithet like Vaccinium pallidum (Aiton 1789), we can locate the species in classification space. The authority (Aiton 1789) tells us where to go for the original classification information, the specific epithet (pallidum) sometimes gives us a hint about a physical characteristic (in this case relating to the color of the leaves) relative to other species, the genus (Vaccinium) places this species in the family Ericaceae, the heath plants, which share similar characteristics.

While a “name” is just what we call something, the scientific “address” tells us where the species currently resides within the complex classification space of kingdom, clade, order, family, and genus.

Many of us change our addresses more often than we change our names, and species are no different. As we uncover new genetic commonalities or differences among species, we reorganize our information space and give them new addresses.

So while the species formerly located at Ericaceae Vaccinium vaccilans may now have moved in classification space to Ericaceae Vaccinium pallidum, it’s still just late lowbush blueberry to me.

A dense thicker of low blueberry shrubs at Montague Plains Wildlife Management Area, in Montague, Massachusetts, USA on 2017 July 15. There is a tangled combination of early (V. angustifolium) and late (V. pallidum) lowbush blueberry plants in the photo. The early are slightly shorter, with more yellow-green leaves, and the berries have mostly gone by, while the late are a bit more vertical in structure have more pale bluish-green leaves, and are full of berries.

Wetterdaten des Forschungszentrums Jülich, das ist sozusagen meine favorisierte Wetterstation, denn ich bekomme in der überwiegenden Zeit die Wetterdaten von Köln direkt und etwas früher als in den Apps, ganz ohne dass ich einen komplizierten Algorithmus beschäftigen müsste. Das gilt allerdings nur, wenn wir Wetter aus der Kölner Hauptwetterrichtung bekommen, weil Jülich da vor uns Kölnern liegt. Ihr wisst schon von woher.

Gezeigt ist hier nun Folgendes:

 Aktuelle Messwerte vom 18.02.2023 10:40 Uhr MEZ; Luftdruck (92 m ü.N.H.N.) 1009.6 hPa; Lufttemperatur  10°C; relative Feuchte 82%; Windstärke 4 Bf, Windrichtung 260 Grad.

I thought most climatologists rejected Wind chill temperatures? Any informed views on #ScienceSaturday?

It's #ScienceSaturday friends ⚛️

I think my favourite story from this week is about another fast radio burst being discovered in deep space -- it's one of the most extreme yet and it might make us rethink about how these signals travel to Earth.
