My big eye-openers (some from postdoc) were more about the sociology of science than the day-to-day productivity: - Even the most blatantly wrong and illogical published work can only be displaced by another publication that explains/does the same phenomenon better; i.e., people are going to keep believing in phlogiston until someone shows them oxygen. If you simply point out inconsistencies in phlogiston theory, in…

Earlier quoted context omitted.

It depends on the discipline, the programme, and (particularly) the country. I did mine in the UK, where the funding is for 3 years and the expectation is ≤4. I managed that (modulo two terms of sick and paternity leave) and so do most others in my field. The quickest I saw was 2 years 6 months, by someone with an impossible combination of intelligence and relentless 9-hour productive days. Some take longer (financia…

I guess that makes sense - in the EU a masters degree is usually required for a PhD which is not the case in the US. That accounts for 1-2 years at least.

I was very lucky to not need a masters, 3 years BEng and then 3 PhD. I couldn’t have done another year. I was dying to get out but the end. My wife did 3,1,3 and I have no idea how she did that extra year.

All of these tips are good, but the “get excited” one has been my secret weapon through life. A professor in undergrad gave me the tip to get excited or even feign interest when reading dense written material in order to retain more. After trying it throughout a difficult class I was amazed at how well it worked. I applied it to every other academic thing I didn’t want to do and noticed immediately how much easier an…

It's hard to remain excited when so many professors don't prepare for lectures, teach outdated material, rely on question banks for exams, and play the part of ball-breakers. I went back to school for a different degree program in my 30s with a fresh perspective and a much bigger drive from 15 years ago when I did my first two degrees. Mind you that it was during COVID but what did I get? A bunch of "read these chapt…

There seems to be an increasing expectation that undergraduate education should be like high school. By the time you start studying at university you should be able to study independently. The lecturer isn’t there to entertain you or to hold your hand.

That seems to ring true, but - it also seems a bit defeatist, don't you think? "Never question a scientific superior?" Not parsing that concept, please elaborate.

I understand the impulse to not want to be defeatist, but sometimes it’s both easier and more productive to stop running into the same walls over and over and instead find the path around them.

If I had written this article myself and titled it “Lessons from my First Year as a Full Time Software Dev” a lot of the bullets would have been the same. Especially the Daily Progress and Get Excited bullets. Those two tend to go hand-in-hand given how often you need to do a thing with the only tangible reward being the accomplishment of the thing.

My wife is finishing up her PhD in American History and I can tell she's getting bored, at least demotivated reading a billion books a week. I've seen this motivation decline in a lot of founders as well 4/5 years into their startups, but I've not seen much reignite the fire. Can anyone recommend any specific tips for staying motivated through a PhD?

Your wife is bored because she’s gotten what she can out of the program, and the dissertation is a slog. I had the same experience. This is why there is a term for people who do the whole program but drop out without finishing the dissertation: ABD (all but dissertation). It’s the one non-degree people feel justified to list on their resume, because it takes at least 4 years to get there, and it’s still quite an achi…

Isn't there an issue that if you take two years off, in the meantime someone somewhere else is doing the same topic and bangs it out and steals your thunder? Does this kind of thing ever happen, or is it more of a theoretical possibility?

Very early on, I noticed that graduate students tend to be idealistic, postdocs extremely cynical, and faculty ruthlessly pragmatic perhaps to the point of occasional shortsightedness. Clearly, something about this progression is expected and normal. I'm a postdoc now, so I'm right on schedule.

I think the way it ultimately works is that you have to be disillusioned from the grade-school fairy tales told to the public about how science works before you can learn to live and work in the environment that actually exists rather than the one you wish existed.

> "Never question a scientific superior?" Not parsing that concept, please elaborate.

tech People above you in that chain will accept limited feedback on methods to attain their chosen goals and will greatly resent questions about whether their selected goals are worthwhile/realistic/rational, or whether their gestalt vision of the field's conventional wisdom is correct.

I also did a PhD and this is all true. I realized many of these things years later. I think many of these points come down to confidence. When you are in the trenches, you really, really do know a lot, and you know it in incredible detail. In fact, in your career, if you leave academia you will probably never know a unique small "thing" in such detail ever again simply because you will have to make something as oppos…

> It is vital that you trust yourself enough to speak up. Yes, the professor is really smart, and knows more than you, but she didn't spend 3 weeks in the lab wrestling with some optical setup like you did and you know some things better then her, better than anyone in fact. It's hard to admit, I know.

It's really not. It was obvious to me about 9 months in that my advisor really didn't know all that much. The professors who really seemed to have technical chops were either new faculty still trying to get tenure, or the rare iconoclast who didn't play the game and had a single grad student. The tenured professors with large research labs were frankly better politicians than they were scientists.

In addition to ringing true, this seems largely in line with Thomas Kuhn's thesis in his Structure of Scientific Revolutions [0], a book which despite its shortcomings, should be required reading for anyone in a STEM field.

Missing from this actionable survey is the skill of answering questions that haven't yet been answered in the secondary literature (books, reviews) or even primary literature (journals). This is, of course, what research and a PhD is all about in the end. In my experience, this fact was the #1 reason why some peers dropped out of PhD programs. They joined expecting a continuation of undergraduate education, which con…

> The benefit of all of this work and discomfort is that you come away with the ability to answer worthwhile questions that haven't yet been answered. And that's a highly transferrable and applicable skill.

This is why I have come to see that PhDs can in some cases make excellent founders. Source: CS PhD turned founder ;-)
