I'm starting physics at university in about 5 months. When I visiting one university to see how well I might like it there, I had a conversation with one of the professors about the employment value of a physics degree. He said something to the effect of "As a physicist you're very desirable. the only one who knows more math than you is the mathematician, the only one who knows more engineering than you is the engineer, the only one who knows more computer science than you is the computer scientist." This impressed me and made me more optimistic about my prospects, until afterwards I put on my economics hat and figured that by comparative advantage I'd be better off just doing math or engineering or compsci.

Physical theories represent pinnacles of human achievement

It's intellectually stimulating

It has a reputation for being a subject that smart people do

3 biggest reasons I chose physics right there. Have I made a horrible mistake?

I double majored in physics and computer science as an undergrad at a pretty good school.

My observation is this:

The computer science students had a much easier time getting jobs, because getting a job with mediocre software engineering experience is pretty easy (in the US in today's market). I did this with undeservedly little effort.

The physics students were, in general, completely capable of putting in 6 months of work to become as employable as the computer science students. I have several friends who majored in things completely non-technical, but by spending a few months learning to program were able to get employed in the field. The physics students from my classes were easily smart enough to do this, though most did not.

To maximize the ease of getting a job while in physics, take a few programming courses on the side. If you apply yourself and are reasonably talented it should be doable.

I think the 'right' approach (for maximizing happiness and effectiveness) is to major in what you find the most enjoyable and do the due diligence to become employable on the side. And maximize any synergies between the two (do programming in physics internships, etc).

I'll ROT-13 my own answers to the questions, but I strongly recommend that you do your best to figure out your own answers to them before decrypting mine. Trying to figure out plausible mechanisms for magic tricks is a way of calibrating your rational thinking skills, in the presence of an adversary (the magician) who is trying to use all your perceptual biases and cognitive shortcuts against you. If you find yourself seriously considering hypotheses like micromuscle reading or subliminal suggestion, then that's probably because the magician has managed to slip a false assumption past your defences!

I watched #3 again and I'm pretty convinced you're right. It is strange, seeing it totally differently once I have a theory to match.

Comment author: shev 18 June 2013 02:01:45AM *  41 points [-]

I strongly disagree with the approaches usually recommended online, which involve some mixture of sites like CodeAcademy and looking into open source projects and lots of other hard-to-motivate things. Maybe my brain works differently, but those never appealed to me. I can't do book learning and I can't make myself up and dedicate to something I'm not drawn to already. If you're similar, try this instead:

  1. Pick a thing that you have no idea how to make.
  2. Try to make it.

Now, when I say "try"... new programmers often envision just sitting down and writing, but when they try it they realize they have no idea how to do anything. Their mistake is that, actually, sitting down and knowing what to do is just not what coding is like. I always surprise people who are learning to code with this fact: when I'm writing code in any language other than my main ones (Java, mostly..), I google something approximately once every two minutes. I spend most of my time searching for how to do even the most basic things. When it's time to actually make something work, it's usually just a few minutes of coding after much more time spent learning.

You should try to make the "minimum viable product" of whatever you want to make first.

If it's a game, get a screen showing - try to do it in less than an hour. Don't get sidetracked by anything else; get the screen up. Then get a character moving with arrow keys. Don't touch anything until you have a baseline you can iterate on, because every change you make should be immediately reflected in the product. Until you can see quick results from your hard work you're not going to get sucked in.

If it's a website or a product, get the server running in less than an hour. Pick a framework and a platform and go - don't get caught on the details. Setting up websites is secretly easy (python -m SimpleHTTPServer !) but if you've never done it you won't know that. If you need one set up a database right after. Get started quickly. It's possible with almost every architecture if you just search for cheat sheets and quick-start guides and stuff. You can fix your mistakes later, or start again if something goes wrong.

If you do something tedious, automate it. I have a shell script that copies some Javascript libraries and Html/JS templates into a new Dropbox folder and starts a server running there so I can go from naming my project to having an iterable prototype with some common elements I always reuse in less than five minutes. That gets me off the ground much faster and in less than 50 lines of script.

If you like algorithms or math or whatever, sure, do Project Euler or join TopCoder - those are fun. The competition will inspire some people to be fantastic at coding, which is great. I never got sucked in for some reason, even though I'm really competitive.

If you use open source stuff, sure, take a look at that. I'm only motivated to fix things that I find lacking in tools that I use, which in practice has never lead to my contributing to open source. Rather I find myself making clones of closed software so I can add features to it..

Oh, and start using Git early on. It's pretty great. Github is neat too and it basically acts as a resume if you go into programming, which is neat. But remember - setting it up is secretly easy, even if you have no idea what you're doing. Somehow things you don't understand are off-putting until you look back and realize how simple they were.

Hmm, that's all that comes to mind for now. Hope it helps.

$250 a year for glasses seems high given that my $90 glasses have been fine since 2008. I do have an extra pair ($40, not titanium framed) for backup, and should get new ones to update my prescription, but $250/year?

If you hate glasses then lasik might be worth it, but I doubt it's cheaper for many people.

Comment author: shev 18 May 2013 06:45:08PM 0 points [-]

Yeah, it can definitely be done for cheaper. In my case going through college and such I got new frames every year or two (between breaking them or starting to hate the style..). The bigger expense was contacts, which we either didn't have insurance for or it didn't cover, coming out to 100-150/year depending on how often I lost or damaged them.

I've never been to a Seattle meetup but I mean to come to this. Maybe a good way to get in the habit.

Comment author: Qiaochu_Yuan 10 May 2013 09:47:17PM *  3 points [-]

"Pretty cheap"? I looked up the prices once in the name of VoI and saw numbers in the range of $2,500. I'm pretty sure I can improve my life more than LASIK would with $2,500 worth of other improvements.

Comment author: shev 11 May 2013 12:46:07AM *  10 points [-]

But if you would spend 2500$ over ten years of glasses- and contacts-wearing - which is very possible, especially if you're prone to breaking them - then it pays for itself already. Or twenty years, whatever, ignoring alternative ways to invest that money. Add in more for the massive convenience of not having to deal with glasses and contacts, too.

This is why I'm going in for a LASIK pre-op next week. I'm certain it will improve my quality of life appreciably and save me money over the long term to boot.

This is an exceptional first LW post! I like the hypothesis in Section 2, that "be yourself" unpacks into "stop transparently optimizing to fit a cached identity".

My main suggestion is that a long post with multiple distinct points is better off split into several posts, because people will start skimming instead of reading after a while, and points 2 and 3 won't get as much attention/feedback as if they'd stood alone.

Comment author: shev 28 April 2013 08:47:29PM 4 points [-]

I just want to point out that I think the phrase "cached identity" is extremely apt.

Regardless of whether cold fusion is possible (who knows), and regardless of whether I am qualified to think it is possible (moderately so), and regardless of whether I think it possible (I certainly don't think anyone has managed it), I would never be convinced by this post.

You seem to think your argument is pretty convincing. Suppose it is. Suppose 99% of laypeople who have no idea if cold fusion is real believe it. Or 100%, or whatever. That has no bearing on whether cold fusion is real or whether I should believe it to be real from your post.

I would believe cold fusion is true on the word of others if they were experts (in nuclear physics). Your argument can convince any number of laypersons, but if it can't convince a significant portion of experts (and there's no reason it would, since it's just appeals to authority and very unconvincing hearsay) then I have no interest in it.

and then it’s obvious that the ass can be “stuck.”

...seriously?

Comment author: shev 30 March 2013 11:38:15PM 0 points [-]

Well, that's the point. It's absurd.

Comment author: ShardPhoenix 23 March 2013 05:40:38AM 18 points [-]

I enjoy Graham's essays and find many of them quite insightful, but they tend to be rather light on empirical evidence, which makes it hard to say how much of the insight is real.

Comment author: shev 23 March 2013 08:10:25AM *  -1 points [-]

Several points:

  • For many of the things he writes about, we can take his clout and background as evidence that his insight is 'real'. It doesn't have to explained via careful science to be true. I think the fact that Paul Graham is saying something, for certain subjects, makes it highly likely to be very-mostly-correct. I'll happily believe it to a high degree unless I have reason not to. I believe the evidence that they're mostly-correct is that he wrote them, and the evidence that things he writes are mostly-correct is that they have been so in the past and that he's intelligent and moreover consistently intelligent, so we have little expectation of a given essay suddenly floundering into bullshit.

  • His insight and way of thinking can be useful even if they are unreal. I mean - I'm sure every essay on that list makes points that can be argued to death or outright refuted by a sufficiently committed pedant. But they still have value. We think in heuristics anyway, for the most part, so it's valuable to glean heuristics from smart people and to see how they think and how their heuristics work (or don't work).

  • Empirical evidence would not really improve many of these essays. For one thing, filling an essay with detailed evidence that isn't necessary for the reader to believe it would probably detract from the quality of the essay. And many of his points are opinions or perspectives. They shouldn't or can't be highly factual. They would become false if they were made hard-and-fast.
