I know some of these words! πŸ˜… I had hoped it would be physics-related but I can sort of follow along

Totally forgot that the first year I ran my physics-based animation seminar course, part of the grade was writing a blog post about a paper. Those posts still exist and are quite good !

is part of what defines us as a species (at least on earth). I think it's meaningful to ask the question if we want to surrender this part of our collective selves.

"Hopefully our AI will find out one day" is a rather miserable ending to the saga of human inquisitiveness, in my opinion.

IMO there is no meaningful difference if science is just a means to an end (e.g. to produce better products).

But science is also the expansion of human knowledge. Like art, it has intrinsic value beyond its marker value. Human curiosity and the pursuit of knowledge

A thoughtful post questioning the rush to use AI to take humans out of science β€” but also other meaningful pursuits like art.

Ich verstehe diesen Kleinschnitz-Kerl nicht. Warum will er unbedingt ΓΆffentlich zeigen, wie sehr ihm Wissen, WissenschaftsverstΓ€ndnis und Empathie fehlen? Ich finde das richtig peinlich.

Ich stimme dir absolut zu, dass er tatsΓ€chlich viel besser ist als die meisten anderen FragebΓΆgen!

Ich fand es nur ΓΌberraschend, dass es dennoch so offensichtlich uneindeutige Fragen gibt …

Was ich meine, ist, dass 100 m und 1 km zwei komplett unterschiedliche Antworten ergeben kΓΆnnen. Wie soll man es also beantworten, wenn man das Intervall von 100–1000 m auf einmal bewerten soll?

if you can walk 100m without too much problems, but have no chance at 1km?

Questionnaires are hard I guess!

(Feel free to ignore me, I just ended up looking at Funcap since it was mentioned in the thread you quoted)

Totally tangential, but considering all the work that went into Funcap55, I'm surprised to see questions like these:

10-Walking between approx. 100m and 1km on level ground (length of 1 to 10 football fields)

There's a 10x difference between the low and high end! How do you even answer that ...

A rather strange twisted-looking smooth shape generated as the volume of space swept out by a rotating and translating sculpture. The left shows an opaque rendering, the middle shows the same shape with surface points colored to indicate the time, and the right shows a semi-transparent view.

There's a new and very neat-looking SIGGRAPH Asia paper on constructing the swept volume based on the path of a moving (possibly deforming) object. Check it out!

What's even a realistic alternative to .expect in many cases? You'd have to go so far out of your way to avoid that you'll likely be introducing new bugs through sheer complexity.

Takk for at du deler, dette illustrerer veldig godt noen av de praktiske konsekvensene som du var inne pΓ₯ i diskusjonen om PRT vi hadde for litt siden.

Utrolig trist at behandlingstilbudet til disse pasientene blir lagt ned!

Fair enough, though you gotta have some serious cognitive dissonance if you're able to sit there and be fooled by the shiny rockets and robots while Musk is pushing a fascist agenda across several continents

A positive version of the future after gutting USAID and causing the deaths of tens or hundreds of thousands of children?

Positive for who? What is positive about humans on Mars when he's killing humans on Earth?

I don't understand how anyone can think Musk has a positive vision

Pastebin.com - #1 paste tool since 2002! Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.

Here you go, I used AI to extract the English text and went over it. It's possible it's not a perfect transcription but I didn't see any obvious errors.

Bluesky character limit makes it awkward, I've uploaded it to pastebin.com does that work for you?

You don't think desperate patients have tried just about anything to get better, including various forms of brain retraining programs? There's a very simple reason why people are still sick: it just doesn't work for most.

In any case, this discussion has strayed, and I'm gonna leave it here
