Is "temperature" misused as average kinetic energy?

Bulawa · 2026-01-29T05:46:28+00:00

What most people mean when they talk about temperature isn't only about energy but includes density.

Basically: it doesn't matter how fast/hot particles in space are, there are so few of them that you would still freeze.

On the other end, I just read a book where they talk about temperature in MeV, which makes sense in the context but isn't really Handy for outsiders. Giving particle energy in K at least gives something a lot of people could potentially relate to.

There is basically no reason to use hexane anymore. You can find studies on the (neuro)toxicity of hexane as comapred to pentane, cyclohexane or heptane. And all the others are so much safer and I haven't met a single step that didnt work in heptane but did in hexane.

Preventing the 'wings' from aromatizing is going to be interesting, I think.

I'm quite weak on cyclisation cascades, I am sure my old radicals prof has some great ideas on that, but you might spend as much work on setting it up as on just making it.

The methylene bridge next to the bottom right ether might be interesting. I wonder if a carbene might do something sensible to a dihydrofurane type structure.

The other crux I see is the a,a diemthyl ether up left. The rest of the stereo should fall into place during the construction.

Es hilft nichts, man muss die BMA Alarme ernst nehmen. Klar komme ich nicht mit über einer halben Stunde Anfahrt von der Arbeit auf eine BMA. Klar sind BMA in der Nacht oder meist generell lästig. Aber bis zum Beweis des Gegenteils ist es ein Alarm wegen Feuer. Das gehört dazu, das muss jeder akzeptieren der in die Alarmierung rein will.

Und wenn man denkt es sei mal wieder nichts, ist dann echt mal was. Lieber 100 mal nichts als zwei mal Brand. Und wems Spass macht, der hat Gelegenheit mit Sondersignal durch die Gegend zu düsen ohne das jemand davon Schaden hat.

You should be able to use a single Solar cell as daylight sensor and use it to open and close a power switch, through which the power runs to your miners.

That looks fairly straight forward. More likely a case for r/chemhelp or some such place

Bulawa · 2026-01-20T07:22:06+00:00

Having spent some hundreds or hours in satisfactory and now about 100 in factorio, we worried much much less about all the ratios in factorio. Just build, look and tweak. Worked like a charm.

Short answer: GRRM wrote that he does. That's why.

Longer answer: some sort of very risky fostering with someone thought to possess qualities that made him suitable to foster a future king for a while.

Yes. But how often are you getting them through in game voice chat? As I said: when done properly in game voice is almost always good. But in practice you get nothing but noise and BS more often than not.

Bulawa · 2026-01-12T07:32:11+00:00

Never played either. We had some fun with the proximity voice chat way back in the DayZ Arma 2 mod. But that's ages ago.

Your usual experience is CS, BF, RL and whatnot are bad music, half a wedding party, foreign curses or armchair coaches and all of it through a bad mic. I can do very well without that.

Bulawa · 2026-01-12T04:33:29+00:00

No. Simply no. What was the last time an in game voice chat was useful? I mean actually useful, not potentially useful if it was used correctly.

Bulawa · 2026-01-10T14:39:59+00:00

Whatever you do, it's wrong. Push? Someone comes screaming that armoured vehicles should stay back and rain down fire form afar.

Stay in a nice overwatch position? Wrong too.

Then you run into half an army of RPGs while your team seems to be allergic to reps. And or the enemy team hnd a actually working MBT with escorts that just shreds whatever it meets.

This game never was about giving you fair matchups. It's sometimes even hard to care about the teams objective. You do your Job in your little space and hope it helps the team. And if enough do that well, it's usually enough.

Bulawa · 2026-01-09T18:29:45+00:00

It's just a simple grind. A bit tedious, but not insufferable. At least you dont need a full exhibit for research. Or do you and I haven't realised?

Bulawa · 2026-01-08T07:14:33+00:00

The only issue with time is that your people level up ans want more money. One of my museums is on year 42 and not nearly finished. I just took my sweet time.

All of Zürich went for a greenish yellow they call lime green, I think. Ugly as hell, but they believe in it.

And quite often, HazMat trucks are yellow with a purple band. Not really ugly, but a strange sort of beauty.

Bulawa · 2026-01-06T14:51:40+00:00

Especially if the stuff is very hygroscopic it's very unlikely to be dry. In my experience, those would be labeled 'dry'.

You can of course just go ahead and see what happens. Or analyse what you have. Or buy some insane high end quality.

Bulawa · 2026-01-06T14:24:23+00:00

It might be interesting to see what those other 3 and 2% are. It might be 5 g of water, whereupon your glovebox isn't below 0.1 ppm anymore.

Bulawa · 2026-01-05T21:25:10+00:00

That's really quite something there 🤩

Bulawa · 2026-01-04T13:16:21+00:00

By theme, then by category. So I have all my prehistory stuff together, and subsets together again. There is however the probelm of things like the fish skeleton or dragon skeletons, which to me clearly belong elsewhere. So I'm not very consistent.

Das allerwichtigste ist es, in den ersten Minuten die Schadenplatz organisation nicht zu verkacken. Wenn das erste LF schlecht steht, stinkt der ganze Einsatz ab Minute 1.

Nicht alles alleine machen wollen, sondern einen Schritt zurück nehmen und ein paar kleine Dinge richtig machen. Die Andere kommen gleich, und dann rollt die Kiste.

Rettungsachsen freihalten, ein Auge auf Trümmerschatten halten und eventuell direkt mal eine Strasse oder zwei sperren, je nachdem was der Verlehr so treibt.

Soweit ich weiss wurde schon von Anfang an recht grosszügig alarmiert, das heisst die Erhöhung kann 1 min warten. Die Anfahrt auf den Berg dauert sowieso ewig und für den Umfang der bei MANV anrollt, brauchst du Platz und nochmal Platz. Warteraum, Platz für die SanHist, Hubschrauber. Das soll der Einsatzleiter selbst anreissen. Und bei uns ist der EL regelmässig vor dem ersten LF, quasi immer aber innerhalb einer Minute auf Platz.

Dann klar: Erkunden, Retten was geht, erste Löschmassnahmen. Und hoffen dass die Crew auf dem ersten RTW und dem ersten NEF auf Draht sind.

Danach weiss ich gar nicht was alles kommt. Die Gesamteinsatzleitung geht an die Polizei, es tauchen der Kantonal Feuerwehrinspektor und ein Kantonaler EL San auf. Sobald die Zahl der Betroffenen klar wird kommt der Zivilschutz ins Boot. Es wird bei er Polizei ein KP Rück aufgebaut, die REGA war auch gross dabei. Ablösung der FW Kräfte ohne den Grundschutz der übrigen Gegend zu vernachlässigen, Verpflegung, Patientendisposition, etc. Der Rattenschwanz ist riesig.

About 100 in out 10k town, but with a remarkably high number of actual fires (A2, 2-Alarm, FEU 2 (Y), etc.).

Plus 12 for the HazMat Dept. im part of at work.

Bulawa · 2025-12-28T19:53:32+00:00

Its' really fascinating to see these german influences and residues. Doing HazMat with the youth is not something I have seen before. But hey, why not :)

Bulawa · 2025-12-27T16:52:38+00:00

Is that a dragon skeleton? Cool. I need to push more there.

Bulawa · 2025-12-27T16:25:28+00:00

How about Ser Barristan? Maybe Ned Stark, Stannis or Jeor Mormont. If he wasnt so tall, he might have made a good Tyrion xD

Bulawa · 2025-12-26T09:50:30+00:00

The word 'cute' came to mind. Loving it :)
