Hey #bochum and #Ruhrgebiet , tomorrow @scienceslam.de takes over the stage of Schauschpielhaus Bochum!
Five speakers, five topics, five talks, yours truly among them.

Some tickets are still available, if you can make it - come nerd out together ;)

this one from @phdcomics.bsky.social but also this overhead office light is deeply disturbing
PhD comics "A friendly reminder" - https://phdcomics.com/comics.php?f=1785 A four-panel comic. It shows a grad student in bed | at lunch | cycling | in front of a computer. In first three panels they have thinking bubble "I should be writing", The last panel features a headline "You should be writing", and the grad student exclaims "I know!"

What? Ultrasound people? Time again to hit that button
Still from TV show a la Voice, one of the jury desperate to hit the BIG RED BUTTON, one hand is raised, elbow as high as shoulder, hand is level with head - the said button replaced with blue one with text "Follow all"

Speaking of oils, I know pumpkin seed oil as example, gives back nice red
Blue laser pointer shines into a small glass container with about a centimeter-thick layer of pumpkin seed oil (bottle is visible to the right). Blue light reflection is visible on glass, oil surface shows a bright red dot

I've got myself 3.5 mm jack version, I think, under 20€ on amzn, works fine for "hybrid format presentation and speaker moves around a lot" situations.
Right now would probably opt for Bluetooth transmission, back then selected jack as "omnipresent"

Was das alles noch schlimmer macht, eine kann sich so eng mit seiner Wissenschaft schmelzen, so versteht selbst wo die Grenzen sind, und was eine tatsächlich kann. Scheuklappen ohne Ende.
PhD comics, Doktorand*innen schaut auf PC und denkt sich: "Hier stimmt was nicht... Es muss etwas nicht mit meinem Daten stimmen... Das heißt ich mache was falsch... Was heißt etwas stimmt nicht mit mir!" Letzte Spalte, einen Schrei: "Meine Daten und meine Leben sind unbedeutend!"

Sometimes, in the right audience, under very well controlled conditions, and by trained personnel, sticking your hands into a laser beam is appreciated and cheered on*

*please do not attempt at home

We find a significant shift in the frequency of certain tokens in ICLR 2024, with adjectives such as “commendable”, “meticulous”, and “intricate” showing 9.8, 34.7, and 11.2-fold increases in probability of occurring in a sentence. We find a similar trend in NeurIPS but not in Nature Portfolio journals.

Having a life _AND_ trying to work in academia? Sometimes it feels you have to pick one.

Reminded me of this illustration by Liz Fosslien

#AcademicSky
"How adulthood feels" by Liz Fosslien: On a sky blue background a slightly darker octagon, saying "Pick three." In the corners of the shape: work, hobbies, exercise, eating healthy, family, romance, sleep, seeing friends

Honestly I thought of this comics reading your description
phdcomics.com/comics/archi...
PhD comics "What your Prof read": it shows grad student sending a rather long email starting with "I finished..." and further going into details, out of which their Prof only see, and reply to "I finished", as if there were no other text https://phdcomics.com/comics/archive.php?comicid=1209
