@maithinkx.bsky.social Betrifft dein musstewissen Video "Was ist Elektronegativität?" ΔEN(Fluorwasserstoff) = 1,9; trotzdem Moleküle. ΔEN(Kupfer(I)-iodid) = 0,6; trotzdem Ionenverbindung etc. Es gibt zu viele Ausnahmen von der Regel + polare Atombindungen reichen nicht aus für Dipolmolekül.

#ein_tag_im_september Sorry, but when I hear about De Gaulle & Adenauer or Mitterand & Kohl forming personal bonds and that being a boon to democracy and freedon, I immediatly think of Trump, Putin, Xi or Kim forming personal bonds. It's not the personal bonds but the ideas of the bodning people.

Distracted boyfriend meme. Boyfriend is "Patrick Matthew (1790-1874)", his girlfriend is "Species fixity through competitive selection" and the distraction is " Speciation through natural seletion by Darwin (1859)."

Am I the only one who dislikes the literary genre of using dialogues in philosophical writing? It began with Platon and went downhill from there.

Since I see "types of ___ papers" making the rounds again, I figured I'd repost what was probably my most retweeted post on that other site: types of #philbio papers.

I'm surprised to learn from Radick's 'Disputed Inheritance' that Mendel's laws are not simply taught, in Britain, as the uniformity of hybrids from pure breeds (1. law), the 3:1 ratio in the F2 generation (2. law) etc. Never heard of the 1. law as referring to gene pairs (alleles) etc. #hps #evobio

An editorial on data sharing in the New England Journal of Medicine stated: 'There is concern among some front-line researchers that the system will be taken over by what some researchers have characterized as “research parasites.”' www.nejm.org/doi/10.1056/...

The referees feel that our paper would have been better if it had been a different paper. Not sure I can be bothered to argue this one.

One of the very few philosophical ideas that have been resoundingly falsified is Popper’s falsificationism.

People who claim Dunning-Kruger effect for others and impostor-syndrome for themselves are usually just Dunning-Kruger-stupid and mistaking the first inclings of a realilstic self-assessment for an impostor-sydrome.
