TL;DR; Mein Lieblingsthema Bedingte Wahrscheinlichkeiten, Bayes, und Sigmas Ich habe jetzt mal meine Bedingte-Wahrscheinlichkeiten-Predigt gehalten, und am Beispiel Masernfälle in Disneyland durchgerechnet, weshalb 18% Geimpfte unter den Erkrankten nicht bedeutet, dass das Vakzin schlecht wirkt. Es ist einfach immer spannend, wenn Mathe so unmittelbar Alltags/gesellschaftsrelevant wird und in so schön konkrete und quantitative ethische Überlegungen einfließt.

@darkuncle@infosec.exchange @gregeganSF@mathstodon.xyz broken as in it's a grift. Publishers don't add anything of value anymore in my opinion.

@Bumblefish@mastodon.scot @darkuncle@infosec.exchange @gregeganSF@mathstodon.xyz If you look at what utter deranged drivel some former Springer Nature execs I know are saying about scientific publishing, my verdict is that they must be giving themselves kool aid IVs. Exhibit A: NPT on LinkedIn the other day

@xyla@shitpost.trade That locomotive wanted some Freilassing indeed

@woo@fosstodon.org @lankohr@mastodon.social @kibcol1049@mstdn.social It's even worse - if knowledge is a high dimensional sphere, the surface grows extremely quickly with r^(d-1), and almost all your knowledge is at the boundary to the unknown.

@noracodes@tenforward.social I'd be surprised if you didn't find the right nerd for your problem on here ^^

@dr_jo_mue@troet.cafe @xyla@shitpost.trade Maybe what they mean is that as opposed to France with their centralized LGVs running through from the periphery to Paris, we have a bit of a patchwork of very high speed lines and slower lines shared by other services and cargo, requiring more slowing down and waiting on any given trip, but still, I think it'd be pretty decent network with better coverage if they maintained everything properly

@petergleick@fediscience.org I see a lot of highly educated intelligent people who doubt the reliability of the climate science account. My impression is that a lot of "intellectual doubt spreading" (*) is going on in libertarian circles which really resonates with this clientele, but I don't really understand what's going on. Of course, if you're of the libertarian persuasion, rejecting agw is especially tempting. (*) along the lines of, models can't predict this because it is too complex, etc.

@boris_pohler@bildung.social Ich bin nicht politisch neutral im Physikunterricht, wenn damit gemeint sein soll dass ich nicht Standpunkte der Parteien thematisieren und konmentieren und mit SuS diskutieren darf. Beutelsbacher Konsens hat ja auch das Kontroversitätsgebot. Ich gebe halt keine Wahlempfehlung ab

Can we for concreteness discuss this DIY arrangement from https://homebrewcorner.blogspot.com/p/pa-150-hf-linear-200w-amplifier.html just as an example for the kind of design I am talking about. This apparently uses such a push pull configuration with two separate core halves. The OM says they get appropriate power levels out of this and there is no reason to doubt the measurements shown. But how? Is this due to high quiescent current settings making the "off" transistor still do some work on the other half wave, or do the parallel caps work some magic here? #hamradio#electronics

@sudo200@layer8.space Ah, entropic cooling, excellent

@gregeganSF@mathstodon.xyz Is it maybe still true with some additional constraints which were implicit in peoples' intuition all along?

@VeroniqueB99@mastodon.social or the afterlife

@MicroSFF@mastodon.art Nuke it from orbit, it's the only way to be sure

@jackemled@furry.engineer aha let me guess you kept /dev/ iant

@stevewfolds@mastodon.world @lankohr@mastodon.social @woo@fosstodon.org @kibcol1049@mstdn.social Well, Socrates has a word to say about that predicament... https://en.wikipedia.org/wiki/Xanthippe?wprov=sfla1

@DC4DD@sueden.social ok doch kein Astra? Ich bin mir nur nicht sicher, ob es einen Unterschied macht und die nicht eh alle den gleichen Kram da reinstecken. Eigentlich bräuchte es eine offene Plattform.

@upofadown@mstdn.ca In my LTSpice, it shoots up, will show later

@fullywoolly@mastodon.social Yes, so the trouble is that these two halves of the primary windings fed by the two transistors are in separate cores (see photo) which are not coupled magnetically in reality

@upofadown@mstdn.ca What you describe is the reason why transformer coils don't behave like inductors. In our case though, we have exactly the problem that the *primary* on one side is open circuit because the transistor is off, making that part of the *secondary* behave like a high impedance inductor in series with the load, at least for every other half wave that is. It looks rather pathological in LTSpice, too: second picture is the "good" case where all output transformer coils are coupled together, first picture the non coupled case of two side by side ferrite sleeves, each coupled to one transistor.

@VeroniqueB99@mastodon.social Questionable is an understatement for packing Coors Light.

@DC4DD@sueden.social Ich ziehe den in Betracht wenn unsere alte Mühle den Geist aufgibt, daher bin ich interessiert wie der so tut

@xkcd@mastodon.com.br Well, the mammals had a good run...

@hausderastronomie@academiccloud.social Schade, dass ich im Urlaub bin!

@vk3kri@mastodon.radio This is a bit enigmatic. He acknowledges the fact that the two half transformers are not coupled and need T2 for an artifical center tap: but then goes on to talk about leaving out T2. I wonder how he would realize the T3 windings in that case, this remains very vague?

@carnage4life@mas.to What is the source of this?

@jackemled@furry.engineer i know i know ^^

@VeroniqueB99@mastodon.social Fun fact, these may look like horses, but actually evolved from Rabbits.

@jonty@chaos.social O eye see

@vk3kri@mastodon.radio @upofadown@mstdn.ca I always naively thought otherwise until I built one of those double hole things and measured it with a VNA. Then I realized that something is terribly off and was initially confused what had gone wrong.
