People found that `m * v` is the quantity which is conserved.

There's no understanding. It's just a formula which matches the observations. It also matches our intuition (a heavier object is hard to move, etc), and you feel this connection as understanding.

Centuries later people found that conservation laws are linked to symmetries. But again, it's not some fundamental truth, it's just a link between two concepts.

LLM can link two concepts too. So why do you believe that LLM cannot understand?

I middle school I did extremely well in physics classes - I could solve complex problems which my classmates couldn't because I could visualize the physical process (e.g. motion of an object) and link that to formulas. This means I understood it, right?

Years later I thought "But what *is* motion, fundamentally?". I grabbed Landau-Lifshitz mechanics textbook. How do they define motion? Apparently, bodies move in a way to minimize some integral. They can derive the rest from it. But it doesn't explain what a motion is. Some of the best physicists in the world cannot define it.

So I don't think there's anything to understanding except feeling of connection between different things. "X is like Y except for Z".

Consistent bugs you can anticipate and play/work around, random ones you can’t. Just look at pretty much any speed running community for games before 1995.

This is a physicist who could likely make much more in the private sector. That's a compromise I've had to make too. I spend my weekdays doing work that I have little interest in and has less chance of improving the human condition, but it let me buy a house and pay the taxes and fees. If I instead choose to do what I'm interested in I'd be lucky to afford renting a room in someone else's house.

I admire the guy for choosing to do more important work and making sacrifices to do it. But I'm not owed a decent salary in return for following my own dreams rather than my employer's dreams. Nobody is.
> Shortly after, the tides changed and we were all using spaces.

Very interesting. Thanks for sharing this information! What do you think might have caused this though?

> Who cares about grep?

I do care. I find it much easier to work with a codebase that has logs and error messages that can be easily searched. Similarly, working on a blog with searchable text makes more sense to me. Before switching to soft-wrapping, I used hard-wrapping, and sometimes I would notice a typo or an issue in one of the essays. When I tried to quickly search for a nearby word, it wouldn’t find it because the text had been hard-wrapped. I think it also makes it far easier for outsiders to navigate a repo which they are not familiar with.

About the newline, I agree.
> As a complete lay person with little to no physics knowledge: what stops the use of something dumb like a parachute, or even wings and landing gear, to "land" the booster?

The main advantage is that you don't need to spend any of your payload mass budget on a parachute, or wings and landing gear. The secondary advantage over a parachute is that you don't need to fish it out of seawater and make your refurbishment process more of a pain in the ass.
I migrated from Hugo to Astro and by that I mean I had to basically start from scratch. I'm using it but suspect Astro will be the next Hugo in a few years time. It is not overly simple in any way.

Some labs do but that is a bunch of extra labor that they need to manage. Sometimes some labs do more sequencing than others and they might have more researchers to do the regular sequencing. Many labs are smaller and can't afford to hire so many people or buy so much tertiary equipment. Grad students are already overloaded so they probably don't sequence unless its directly a part of their project

At least for the retro-propulsive landing burn, I think the modeling problem is probably aided by the high G-forces that must keep the fuel very close to the bottom of the tank. Even before re-light the booster is falling near terminal velocity (I think?), so the fuel is likely sitting at the bottom.

I think it's a huge problem when re-lighting the engines in orbit, though.

I highly doubt it’s a product of the raw training dataset because I had the opposite problem. The token for “background” introduced intense blur on the whole image almost regardless of how it was used in the prompt, which is interesting because their prompt interpretation is much better.

It seems likely that they did heavy calibration of text as well as a lot of tuning efforts to make the model prefer images that are “flux-y”.

Whatever process they’re following, they’ve inadvertently made the model overly sensitive to certain terms to the point at which their mere inclusion is stronger than a Lora.

The photos you’re showing aren’t especially noteworthy in the scheme of things. It doesn’t take a lot of effort to “escape” the basic image formatting and get something hyper realistic. Personally I don’t think they’re trying to hide the hyper realism so much as trying to default to imagery that people want.

The dominant variable is how often they can reuse the stages. Last I heard Musk was targeting dozens of reuses for the upper stage and hundreds for the booster. If they are short of the cost per kg goes up.

Of course. On the other hand, one has to wonder which of this two occupations helps humanity more, and it's this the one that's paid better. And if not, should we rethink the way we reward work to prioritize things that help society instead.

I think your question mainly demonstrates how much trouble most people have about reasoning about exponentials. Not intending any personal insult, but unless you do it regularly (ie, probably are a physicist), you will use a term like "highly improbable" when referring to quantities that can only be expressed in scientific notation.

In other words, most humans have bad intuition about large numbers. And I'm not talking about "small" large numbers like "how many Teslas could Elon buy". I mean "how many atoms are in a chicken egg" (and what are their statistical properties at room temperature)
I can see how frustrating it might be, but the overall idea of SO is "no duplicates". They don't want to have 1000 questions which are exactly the same but with slightly different phrasing. It can be problematic for total newcomers, but at the same time it makes it more useful for professionals: instead of having 1000 questions how to X with 1 reply, you have one canonical question with 20 replies sorted by upvotes and you can quickly see which one is likely the best.

FWIW, I found LLMs to be actually really good at those basic questions where I'm at expert at language X and I ask how to do similar thing in Y, using Y's terms (which might be named differently in X).

I believe this actually would work well:

- extra basic things, or things that depend on opinion etc: ask LLMs and let they infer and steer you

- advanced / off the beaten path questions that LLMs hallucinate on: ask on SO

I think that what is important is to give time for your body everyday to recover from the food intake (which can be an inflammatory insult) and give it time to repair. Maybe some people may reach ketosis in 8h, which is an injury itself. It is like the need to sleep and the need to rest after exercise or the need for vacation after long work days. Every insult needs to be compensated for and repaired.

Also the idea of having to eat 3 meals a day, does not exist in nature or in our past history. This developed with industrilization when hard working men needed energy at work.
But it is clear that evolution never needed to limit excessive food intake. It mainly dealt with famines and low food intake. We never aquired the necessary breaks to stop eating. we need to keep this in our thoughts daily to actively stop ourselves from eating till our death

So they have apparently enough time to read full words, it seems!

$70k is a living wage in Los Angeles; he his homeless by choice. To be clear, I’m not saying he is not underpaid. He might need a roommate and to live in a crappy apartment and not in Westwood to make it workable, which does not seem fair for a PhD teaching physics. But it’s not homeless level.
I expect professors to be homeless too.

Yes, there is a balance. IF you think of your body like a car it can make sense. The more you drive your car the faster it will wear down. Not driving your car can help it last a long time but it is useless. But driving it to much and too fast will wear it down before its' time.

Drive your car when you need to, but not too fast. And make sure you give it good gas and take care of the fluids and maintenance. And live knowing that everything is impermanent and one day your car will be gone.

Cyberpunk is too dark and gritty, in a world enjoying the light and warmth of modernity.

In the 80s the threat of nuclear war, toxic chemicals (dioxins), depleting ozone, etc. not to mention the cultural prominence of the Japanese fueled nerd culture’s flights of fancy and escapism.

Today global prosperity, self awareness, and (shudder) regulation has at least staved off these nightmares we dreamed could be reformed by cyberpunk’s promises.

I do a lot of plasmid sequencing in-house with nanopore, so I have some insights here!

For years, the problem was mainly with the rates of mutations in nanopore sequencing, in particular, non-random mutations. The stuff you couldn't just sort out by sequencing more (well, theoretically at least). This was because of the pore structure. Around 2021, R10 flow cells came out, which were a major improvement on R9 cells. In the protein pore for nanopore sequencing, they basically just stacked two proteins on top of each other, so there are more contact points to get data out of.

With the improvement in nanopore sequencing fundamentals, you now have far fewer non-random mutations. This enables plasmid sequencing. Plasmidsaurus just hit it out the park with convenience of the service.

On cost: most of the cost is in their reliability. Each customer wants their particular plasmid to be actually sequenced - so $15 price tag (and probably much less in-house for them). I currently sequence plasmids for approximately $0.25 in-house, BUT only probabilistically (900/1500 plasmids get sequenced). And to my best approximation, this is a non-random distribution, so just doing it more doesn't fix it. Also you run out of material.

There is an aspect of library prep that is cheaper. Turns out, with illumina sequencing at least, most of the cost is in the indexing step, not the actual sequencing, for plasmids. This is the step of putting barcodes onto the material to figure out which well a particular sequence came from.

Finally, you still do need software! People don't realize how much software you actually have to make to be able to tell plasmid sequence from nanopore sequencing. Plasmidsaurus makes it easy for people. Here is an example from my repo of me figuring out how the hell to interpret some weird data I've gotten:

https://github.com/Koeng101/dnadesign/pull/98

If you want a real example, take a look at this pileup file:

https://github.com/Koeng101/dnadesign/blob/sequencingPileup/...

How to read: https://en.wikipedia.org/wiki/Pileup_format

At position 165, you see a non-random nanopore error that only affects a single side of the DNA, and not the other (there would be lowercase g if the complement was also "mutated"). You need to sort through these to get good data to customers. And that's not as easy (not to mention how often plasmids are mixed!)
The Untold Story of the C-Section
> I’m only being paid $70,000 for this academic year

hmm...

> the period of the year during which students attend an educational institution, usually from September to June.

That's around 100k annualized. Something is rotten in Denmark.
If they aren't completely fabricated.
I am no astrophysicist, but he notes:

“Hi everyone, my name is Daniel, and I’m an astrophysics professor at UCLA. I’m only being paid $70,000 for this academic year,” McKeown says in the video.

McKeown, listed as a lecturer on UCLA’s website, says he had to move out of his apartment because he could no longer afford the rent.

McKeown says his rent was $2,500 a month. According to RentCafe, the average rent is $3,700 in Westwood.

Hrm, I have no idea what his actual situation or bills are. But 70k is not chump change, and 2.5k rent seems "manageable". Lets see, if his is single, that puts tax at 22%. It is probably 30% with state and local, minus SS tax. Lets kick it up to 36%.

(70000-(70000*0.36))/12.0=3733.33

Ok he is left with 3733.33-2500=1233.33 a month, that is BRUTAL, but I know people that live on less than that after a home mortgage and car note.

Again, I have no idea of his situation. Maybe student loans, maybe a car note, medical expenses, etc, but to state out loud that you have probably 1.2k a month after rent and can not possibly live without _a hundred grand_ extra (what he is trying to raise... which is EIGHT THOUSAND A MONTH EXTRA) seems a bit, I am not sure, overreacting? I am just conflicted about this story. I have really good friends that would do a hulluva lot for a 70k job with a 2.5k rent, but at the same time, it is true we are paying professors (and educators in general) far too little.

Is this just to make a statement maybe?
