Since you're not supposed to eat grapefruit while taking meds as it enhances the effects of some meds to dangerous levels, why aren't those meds sold in smaller amounts premixed with grapefruit?

I am still looking for a student (PhD or Master) in Japan who would like a side job in web development. ~8 hours per week, ~1500 to 1800 y/hour depending on your current university grade.

Thought about hypothesis testing as an approach to doing science. Not sure if new, would be interested if it's already been discussed. Basically, hypothesis testing is inefficient because you can only get 1 bit of information per experiment at most.

In practice, much less on average. If the hypothesis is not rejected you get close to 0 bits, and if it is rejected it's not even 1 bit because there's a chance the experiment is wrong.

One way to think about this is error signals. In machine learning we do much better if we can have a gradient than just a correct/false signal. How do you design science to maximise the information content of the error signal?

In modelling I think you can partly do that by conducting detailed parameters sweeps and model comparisons. More generally, I think you want to maximise the gain in "understanding" the model behaviour, in some sense.

This is very different to using a model to fit existing data (0 bits per study) or make a prediction (at most 1 bit per model+experiment). I think it might be more compatible with thinking of modelling as conceptual play.

I feel like both experimentalists and modellers do this when given the freedom to do so, but when they impose a particular philosophy of hypothesis testing on each other (grant and publication review), this gets lost.

Incidentally this is also exactly the problem with our traditional publication system that only gives you 1 bit of information about a paper (that it was accepted), rather than giving a richer, open system of peer feedback.

@neuralreckoning 2 proposals:

  1. Choose hypotheses where both possibilities are exciting (i feel like a lot of null hypotheses are borderline stupid, and that makes them bad null hypotheses. If you look at things like engineering in space, when something goes wrong in a spacecraft and you only have a 2 min window of communication with 2 days to get an answer... people find way to maximize the info out of their null hypotheses)
  2. Use Taguchi arrays

So oral exam at end of PhD. Good idea or just a tradition that doesn't make any sense any more? What are the good things about them? If we didn't do them, how else could we get those good things?

@neuralreckoning I've seen it be a good 'rite of passage' for the student, in the sense that it feels like a more fitting closure than just the moment you hand out the file.
You get the sense of trepidation and release, often followed by a celebratory dinner with your lab, that you don't get from doing the actual important parts (the years of research and months of writing)

Exceedingly cool results.
Somehow, wherever this small bat thrives, its presence also creates a niche for a bigger bat, which evolves from... the small bat. You get a string of islands with the simultaneous presence of the small bat and the big bat that re-evolves from it every time....

The phenomenon is so weird that people thought it was just 2 different species that colonized the islands in parallel. It's just one species with a recurring sub-branch.

A lot of media is leaving out the main point of our paper and cheapening our results :/

The main point isn't simply "look for a bunch of planets that look the same", it's that these planets would DIFFER in a predictable, highly nonrandom way indicating that life is mutating planet by planet, and adapting measures from ecological research we can even tell you how unlikely that arrangement would be: 1 in a thousand, a million, billion?

The whole thread is very informative but the most important thing I learned is that in this day and age even IT companies believe chatbots will understand and obey instructions if you just say please 🙄
People who should know better have gaslighted themselves into believing they have truly built Artificial Intelligence.

How do you pack a 95K word (nonfiction) book into a 40 minute talk?

How many words are in 40 minutes? My estimate is 4-5K. That's ~20-fold compression. Something like half of 1 (of 10) chapters in the book.

Obviously you don't just read off the first half of the first chapter. But an outline of all of it is also super unsatisfying; it needs more depth than that. Clearly you present the central thesis and why it matters. But what to support it? This is a problem I've never encountered before. Not yet sure how to wrap my head around it.

Any advice? Any pointers to book talks you love?

lana,
@lana@mstdn.science avatar

@NicoleCRust I think I'd take just one "case study" or example that makes the point of the whole book if possible, and go narratively through that example keeping only the essential parts of the argument. If after that I noticed there is still time, I might add a second one, or more likely talk about something that is not in the book: some behind the scenes, stuff that didn't make the cut, how did I decide to write about this, what are the reactions to the book so far, any interviews

Remember when the Japan government sent everyone two (!) masks (Abe no mask), but it turned out many of them were defective?

They apparently still have extras laying around, and they use them at a Tokyo kid’s center as name tags. 😳

The kids’ names are stitched on and they wear the mask on their back :gosh:

@FlockOfCats Looks like the straps are used to keep it in place, rather than a stitch. Do you still have the link to the original source? I'm curious now

Anyone in Japan who would be eager to share advice about moving to Japan with a cat? Can I put you in contact with the person needing advice? I can give them tips about the city they're going to live in, but I don't have cat expertise. All I know is it's even harder to rent than with a dog.

Paper purporting to have fascinating results.
Paywalled. It's 2024 people! How is this still a thing! Can you downvote a website??

Shamefully, I have one paywalled Nature paper. We all agreed in advance that we would make it open access (I'm not 1st author). Come publication day, I notice that it's not open access. 1st author checks with editor. Editor says it's "too late" to make it open access now that it's been published, even if it was published paywalled by mistake. These people still live in 1924. (we put the paper on Arxiv.)

My student has done awesome work using Neural Cellular Automata to help designers redesign and clean up images (so far for use in the Kimono artisan industry). We're looking for a place to publish - but, despite the interactive nature of the tool, he's tired of going to conferences for other projects and want to publish in a journal. Anyone has good recommendations of open access journal that would be a good home for this social/computer/design/artisanship work?
Reposts appreciated.

Is offering to add random people as authors on a paper - in order to share and thus reduce publication costs - fraud or a valid response to excessive publication costs and broken performance metrics?

(Not planning to do this myself btw, I'm fortunate enough not to need to, but not everyone is so lucky.)

@NicoleCRust @neuralreckoning @deevybee wouldn't the analogy rather be "is it ok to add someone as a co-author because they owned the expensive machine that you needed"?

Biologists! I received a large .tiff image from electronic microscope imaging. It doesn't show well in any image viewer I tried on Mac. The thumbnail is perfect though, so I know the image is fine. What should I do to see it, or to convert .tiff to .png properly (the usual conversion methods haven't worked)
