This was a beautiful letter to read, with a simple piece of wisdom about life, spelled out for the student.
I am grateful that this was submitted to Hacker News, and that I was able to read it.
Man while Feynman was a genius, I think it's underappreciated just how articulate and philosophical he was. I've always loved reading his work because he just knew how to say things the right way.
This letter really allows that side of him to shine through.
He could would shrink the complex into something that could fit in even my head.
I like this one:
This particle is a perfect ball bearing that can move at a single speed in one of six directions.
from "Feynman the Explainer" in:
https://longnow.org/essays/richard-feynman-connection-machin...
also:
"Don't say `reflected acoustic wave.' Say [echo]." Or, "Forget all that `local minima' stuff. Just say there's a bubble caught in the crystal and you have to shake it out." Nothing made him angrier than making something simple sound complicated.
That is the main reason why he is appreciated imo
> No problem is too small or too trivial if we can really do something about it.
I think we try to think we can predict what are important problems and what are not. Sometimes this is easy and we're right, but often we aren't. This is true in math, physics, and computer science. In any domain. So do what you like because you never really know. Plus, they say interest is worth an extra 10 IQ points.
From all my reading of Feynman I think there's one thing he'd stress: have fun. To never lose the creativity, that child like wonder. In CS we got here because we loved to play around and hack. I hope we never lose that.
This echoes what I have thought about my career. What to work on.
I've been blessed to have a good paying career in software engineering, but I've never really felt passionate about the products I work on. At the end of the day, my job is a paycheck. I do feel joy solving problems for others, improve society, be able to answer colleagues questions when they "come to my office". My family is happy that I can provide and that I am a role model for them.
I sometimes think I should work on things that make me happier. Sometimes I think that my career path is a mistake, I should work on problems "closer to god", make more meaningful contributions, build the next Kubernetes/ChatGPT/Google/<insert revolutionary product>, advance AI, climate change. I end giving up, I'm not that ambitious or driven.
I'm important to my family and colleagues. That may be good enough.
The most important jobs in the world - teaching, cleaning, caring - are extremely underrated. They are lowly paid, and people automatically assume that those doing these jobs are less than.
Sometimes the most important thing in the world is to be a good person to those around you. That can be in extremely short supply to some people.
> That may be good enough.
I would argue it is.
I have had discussions with peers recently around doing the big flash-y <insert revolutionary product>. An interesting analogy surfaced. The nuts in the studs of the infrastructure of the many structurally sound homes in existence are just as important (meaningful) as the doors, windows, and more flash-y features. They may be _more_ important in some cases. They all make up the home.
It made me realize it might not be all about maximizing ambitious pursuits. Maybe it is more about experiencing the joy of solving the next problem and the fulfillment that comes from simply being needed pretty regularly.
I was surprised that after “closer to god” comes the “build the next kubernetes”. How do you connect these two things?
E.g. I’ve found the “closer to god” in my yoga practice. And how I now realize that through words I can’t connect that much as through practice (e.g. just eating my lunch being fully present). I still think I can help through my software product building skills, but also know that if I can help people find a more joyful life / build a less painful body is closer to my purpose than “only” building software.
The vast majority of human existence from million years ago to now is toil. I don't spend anytime feeling bad about being well compensated at an air conditioned office working on CRUD.
It depends on what "working on those problems" means to you. If you want to work on those problems as a software engineer, that sounds like an achievable goal.
To me, the interesting, fulfilling bits of building the next Google/ChatGPT/AI/climate change lie in the theory. Arguably with the exception of Kubernetes, this theory does not come from software engineering. As much as I enjoy software engineering, it's a trade. It's a tool to get the job done. And recently, I realized I like building things just as much as I like "the theory".
To me, that was a bitter pill to swallow. I'm not an ML engineer, but I suspect this is also the reason why you can find so many posts about ML engineers trying to pivot to ML scientist roles.
In keeping with the list preceding "climate change", consider changing it to:
"...advance AI, change climate."
I’m in a similar career situation and I am trying to beat my ego into submission to adopt a similar mindset
Perhaps it’s not ambition or drive but just curiosity. „I wonder if we can …“ -type of thinking.
I don't think so personally, because if its truly from a place of curiosity, then you're in the BEST of place. You're enamored with a specific problem, have some idea of doing it and will slowly explore nooks and crannies to manifest it into reality. The problem here (again, i think) lies in the fact that we don't often see the grander value of our everyday works and yearn to do SOMETHING grander, more impactful, but we don't know which, or how, and in time it will torment us each time we do our normal work. (sorry for the text wall)
> You will get the pleasure of success, and of helping your fellow man, even if it is only to answer a question in the mind of a colleague less able than you.
> innumerable problems that you would call humble, but which I enjoyed and felt very good about because I sometimes could partially succeed.
> You met me at the peak of my career when I seemed to you to be concerned with problems close to the gods.
As problem solvers, we need encouragement to face the difficulties that lie in exploring problems. We need to believe that it can be solved but more so that WE/I can solve it. We need to raise our egos to healthy amounts (not sure what is the precise definition of healthy) so we don't back down or give up. And Mr. Feynman alludes to this with "the pleasure of success", "helping your fellow man", "answer a question in the mind of a colleauge", "I enjoyed ... because I sometimes could partially succeed", and "problems close to the gods".
I am exploring (and absolutely denouncing) this egotism for it leads to frustration, disconnection, illusion, entitlement, and shielding. I feel that (good) school/university/work environments raise ego levels (with "good job!") and aloof you from _........ (which is a utopian place with a healthy encouragement to do more work and work harder to a point where it does not overwhelm you).
The identify of this _........ place keeps occuring to me and flees from me as quickly as it occurs to me. If there is anyone who works without ego, please let me know.
Original sin mate. We must suffer an appreciation of the divine while being simultaneously unable to fulfill it. Accept you humanity and be kind to yourself about it.
> "...Do not remain nameless to yourself – it is too sad a way to be. now (sic) your place in the world and evaluate yourself fairly, not in terms of your naïve ideals of your own youth, nor in terms of what you erroneously imagine your teacher’s ideals are..."
Wise words
Thanks a lot for posting this. I highly recommend having a look into the mentioned flexagons. This is a child toy where Feynman laid the mathematical background and it is very fascinating toy which you can easily build yourself. Try it out - it is really fun. No child required except yourself :)
I read this letter and then immediately read another discussion on HN, A new pyramid-like shape always lands the same side up

This is a great post. Totally resonate with the thought of solving something that gives you the "win" feeling and it doesn't matter whether its small.
Beautiful. Tear to my eye!
I think this is a rare mix of deep humanity and intellectual thinking in one essay.
Lol then... I saw who wrote it!
Good advice for all HN. Often you see a comment and bio shows an amazing career. However they couldnt be amazing without rest of us being average (average of something...). Can't have a max without a median.
“studying the Coherence theory with some applications to the propagation of electromagnetic waves through turbulent atmosphere… a humble and down-to-earth type of problem.” -> Ended up being a very important (and largerly solvable!) problem in ground-based astronomy
Wow. I didn't know about this letter. It's very inspiring.
I read this letter for the first time many years ago when I was in my physics undergrad and thinking about starting grad school. It still crosses my mind pretty often as a postdoc.
read this right after fighting with a timezone bug in a prompt chain. that line about solving what you can felt somehow weirdly the emotional mirror of dealing with race conditions in distributed systems. everything's async, global, flaky but you can only reason locally. idk why my neurons went this way, but kinda clicks in a way to me atleast
Thanks for posting this. Wonderful letter.
In 1 sentence: Do the opposite of trying to solve the Collatz conjecture.
You are not nameless to me. Do not remain nameless to yourself – it is too sad a way to be.
His words and advice are truly inspiring and I agree with him.
However, things have changed a lot. Nowadays we're bombarded with ideas and incredible "opportunities" of stuff we can make. It's almost like ideas are shoved into people's heads.
So, I have to add to Mr. Feynman's words an update:
_Be sure that the thing you want to solve is really the thing YOU want to solve_
This is specially true for software development and closed platforms. Sometimes, software vendors have this way of making developers work for free for things they won't get back, ever. They'll do conferences, and attract people, and show you all those nice tools you can use to solve problems (as long as you use their paid platform).
Don't fall for that shit. Remember Twitter and Reddit closing their APIs, platforms being discontinued, companies cannibalizing successful apps by independent developers. Those people wanted to solve problems, and they got scammed.
I agree. IMO understanding what one really wants to work on, leads to an important line of philosophical questioning to understand 'who am I'. There is a surprising amount of clutter and external influence in our minds.
> to understand 'who am I'
I don't worry much about that. I can be lots of things, change my mind, etc.
Highly off-topic. But I just want to inform you all that the only entry for Rob Pike on this web page under "texts" is a cheese cake recipe.
Sad that he was a jerk and inspired a bunch of students trying to be smart jerks. Did a lot of important research.

I can't comment on the behavior of his students, but his ex-wife told the FBI that Feynman flew into violent rages and choked her on several occasions ( https://en.wikipedia.org/wiki/Richard_Feynman#Personal_and_p... ). I've always felt a bit queasy on reading that.
Interesting link.
Another quote from that same link, from that same hateful person whose first grievance was that Feynman was just interested in calculations and playing the drum :
"I do not know—but I believe that Richard Feynman is either a Communist or very strongly pro-Communist—and as such is a very definite security risk."
Astrophysicist Angela Collier's video essay "the sham legacy of Richard Feynman" [0] is a good introduction. Her accounts of her own encounters with "Feynman bros" are heart-wrenching.
She seems to have missed the real reason why Feynman became so "popular": his series of textbooks. Maybe his name is not associated with such historical discoveries as those of Newton, Boltzmann or Einstein are, but writing one of the best textbook series is also a good reason to be famous, at least for as long as the content will remain relevant. Feynman, to me, is the American Landau: A mathematical and scientific genius whose immensely valuable legacy consists of teaching and textbooks rather than any novel breakthrough in theory.
Apart if you want more clicks on YouTube, I don't think it's fair to call him a sham, unless you believe every popularity is a sham, but I don't think it's the case being made here.
What a baffling comment. Feynman won a Nobel prize for his work on quantum electrodynamics, and yet he's not known for theory work?
Also, Feynman never wrote any books. His "textbooks" are lecture notes, mostly compiled by other people.
Are you serious?
I am. Are you?
