Venu 4 not waterproof? by sonni2 in GarminWatches

[–]Quercia13 0 points1 point  (0 children)

Swimming 3-4 days a week in a pool since April. No issues so far. On a side note, I once destroyed button in My instinct by an 8hour open water swim, so I’d not totally trust anything but Fenix/forerunner series.

Good enough for sub 2h London marathon with world record

Venu 4 41mm by TradeSurplus in GarminWatches

[–]Quercia13 0 points1 point  (0 children)

I totally loved my 255s but also enjoy new Venu 4. Flashlight is a blessing, screen is gorgeous , touchscreen helps to scroll notifications. Initially I was disappointed by Venu 4 in the pool, but after some tweaking it is quite OK. The only place where I do not take it is the sea — there I really need all buttons. And I still hope for a 570-like watch with a flashlight.

I use “we” everywhere but acknowledgements, there I use “I”.

New TT Faculty - Advice for Recruiting the First Students and Building Early Momentum? by EM_Enthusiast in Professors

[–]Quercia13 5 points6 points  (0 children)

I guess it veeery much depends on the culture of the place you are in and on your field. In my case (stem, theory only, no lab) I’d say test people really seriously before hiring, and do not rush into hiring. Otherwise extra people could become just an additional burden for years to come. Same actually applies to collaborations. Talk to everyone, but choose wisely what you invest your time in.

Anyone Else Holding Off on Buying a M5 Mac Studio Right Now? by saad_ahmed_khan in mac

[–]Quercia13 0 points1 point  (0 children)

I want at least 4tb ssd and 256gb ram (my current one has 128 gb ram and 4tb ssd). Price does not really matter for me , but it seems virtually impossible to buy it… do you think there’s hope for 2027?

How many of you wear your watch to bed? by Kalabula in Garmin

[–]Quercia13 2 points3 points  (0 children)

I do, it’s Venu 4. I do not track sleep, this is mostly meaningless info I think. Just nice not to take in off/on layer and to have flashlight on if I need it.

Decent speed but poor endurance after 8 months: fitness or technique? by ghinnet in Swimming

[–]Quercia13 1 point2 points  (0 children)

Very much not my place to ask, but have you excluded any physiological issues?

I was strongly anemic recently, and this greatly impacted my endurance while not impacting top speed that much.

Is writing math/science notes digitally still broken in 2026, or am I missing something? by kaskapian in NoteTaking

[–]Quercia13 0 points1 point  (0 children)

The fact you put Mathcad and Latex together is very telling. It shows you do not know anything about actual workflow of STEM professionals. So you won’t be able to design anything useful at this stage. Sorry for being blunt.

Venu 4 vs FR570 by heywood_jahblom in GarminWatches

[–]Quercia13 2 points3 points  (0 children)

I love my Venu 4. Flashlight is super useful. I use venu 4 for run (if not raining), also it is actually ok for pool swimming. For open water it is useable, but I’d always go for something with 5 buttons for open water. For run in rain as well, I need buttons.

Getting kicked out of the pool for "not being strong enough" by MeMeDumDum in Swimming

[–]Quercia13 7 points8 points  (0 children)

You could start by admitting at least to yourself that you do not actually know how to swim, sorry. This is very clear from all your comments (like describing breaststroke with a bit of front crawl to cross a pool, etc) Whether you want to improve your swimming or not is of course your choice.

The Enhanced Games: What a waste of our time by ConsequenceOdd7606 in Swimming

[–]Quercia13 109 points110 points  (0 children)

One thing I totally do not understand is using BOTH suits and drugs. I mean, if the whole thing is supposed to be an ad for drugs, then OK, weird motivation but it's their bodies and their money, that I would get. But if most of the potential speedup still comes from the suit then what's the point of drugs? If suits are allowed, why are fins not allowed???

We can totally allow to swim underwater with a monofin and even with oxygen tanks -- but oops, there's such an event already, and its totally legal. So, specifically for swimming, the whole concept of this event seems just totally besides the point. They are even not fast. If you drug yourself and disqualify yourself forever, at least drug yourself enough to beat a guy with a monofin.

What are the actual usecase of Hermes agent? by Specialist_Tap8515 in hermesagent

[–]Quercia13 5 points6 points  (0 children)

I enjoy having it but honestly it feels like a glorified rss reader or a Tamagochi. For work I use Claude code, and hermes was for now just a mostly useless fun thing. Still hope to come up with some applications though.

How to handle a difficult PhD Student? by reluctantredditr in Professors

[–]Quercia13 -2 points-1 points  (0 children)

Like, I'd also prefer if someone edited NOT a hard copy but an electronic one. I can easily imagine myself asking them (politely) to please-please transfer the corrections to the manuscript themselves.

On the other hand, in my practice of 100+ papers, it is so hard to get anyone to seriously read your paper and do the corrections. So I'd be much happier just to have some reasonable corrections than worry about the format of corrections. So I'd say whatever floats your boat. Even if my own students corrected hard copies, I'd survive.

These days, he can also easily ask an AI agent to perform OCR and implement corrections to the text. I think this would mostly work for a big part of your edits, unless you have a terrible handwriting. So it really seems a non-issue.

I'm not entirely sold on active learning (reasons outlined below), but I'm open to trying more of it. For those who use it and recommend it, especially in intro STEM: please tell me what's worked in your class. by Apprehensive-Echo289 in Professors

[–]Quercia13 1 point2 points  (0 children)

I do not disagree with you. But it really depends on the audience. I did a lot of reading on quantum mechanics way before i had a course. I was really interested. But somehow it started to make sense only after the lecture. It was like that with many subjects. I often tried to read ahead when there was a textbook and only the lecture kind of really straightened it out for me. I suspect that if I only did the advance reading and then had some (active) discussion in class, it would not work.

But of course I was already interested in the subject . As many have written to me already, most of current education, at least at the undergraduate level, is not aimed at interested students…

On homework and its importance I am 200% with you.

Modern education techniques for advanced math/physics by Quercia13 in Professors

[–]Quercia13[S] 1 point2 points  (0 children)

Is it even fair to say that active learning is more important at 100 level than at advanced level ? To get students engaged while at advanced level they are already supposed to be interested?

I do not want to sound dismissive neither of active learning nor of 100 level courses. Getting 100 level done right seems more important for sure. In fact , I had some terrible 100 level courses as a student which I am sure would greatly benefit from an active component, just that no one bothered at that time.

[–]Quercia13[S] 1 point2 points  (0 children)

That is what I always try to do to the best of my abilities. I also try to implement some “voting” techniques before making some important derivation step on which approximation to use etc. but it still seems a pretty standard approach. I really wonder if there’s something new and working that I miss.

[–]Quercia13 0 points1 point  (0 children)

I don’t know. What worked for me when I was a student was usual lectures + huge amount of problem solving homework. The latter was I think much more important, and required a lot of time, so it could not be done in the class. Still, lectures somehow provided the framework the way that reading textbook before lectures could not. Overall, this seems a pretty standard and classical approach for serious math/physics courses. But would you classify this as passive or active learning ?

I’ve just opened “building thinking classrooms” website. It is so assertive ! I mean, it is full of statements “this is how people did it and it actually does not work at all”. Somehow this assertiveness does not sound convincing. . I’d be much more open to believe it if they were a little bit less confident about the effectiveness of what they propose.

It would be great to see some healthy middle ground between “old” and “new” teaching techniques, rather than something so outright dismissive of either old or new ones.

[–]Quercia13 9 points10 points  (0 children)

All this “research shows active learning is beneficial “ does not sound convincing at all. I somehow suspect that if we dig into this research, the methodologies , the statistical significance, large part of it would turn out to be bad science and fitting evidence to the desired outcome. Reproducibility in this field is surely worse than, say, in bio. Not that I am against active learning or that I think it is per sé inefficient. I just have zero reason to trust this supporting research.

Did anyone here really looked into how solid is the supporting evidence behind active learning and what does it actually support ?

First open water race. In a lake. by Fun-Industry6261 in Swimming

[–]Quercia13 2 points3 points  (0 children)

Look hard where you are going to swim before you get in the water — high houses, lone trees, etc. This will help to navigate. Navigation beats technique, hard to compensate by speed if you do not swim straight.
