A few notes about the community
If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.
A list of some posts that are pretty awesome
I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:
- The Worst Argument in the World
- That Alien Message
- How to Convince Me that 2 + 2 = 3
- Lawful Uncertainty
- Your Intuitions are Not Magic
- The Planning Fallacy
- The Apologist and the Revolutionary
- Scope Insensitivity
- The Allais Paradox (with two followups)
- We Change Our Minds Less Often Than We Think
- The Least Convenient Possible World
- The Third Alternative
- The Domain of Your Utility Function
- Newcomb's Problem and Regret of Rationality
- The True Prisoner's Dilemma
- The Tragedy of Group Selectionism
- Policy Debates Should Not Appear One-Sided
More suggestions are welcome! Or just check out the top-rated posts from the history of Less Wrong. Most posts at +50 or more are well worth your time.
Welcome to Less Wrong, and we look forward to hearing from you throughout the site!
Once a post gets over 500 comments, the site stops showing them all by default. If this post has 500 comments and you have 20 karma, please do start the next welcome post; a new post is a good perennial way to encourage newcomers and lurkers to introduce themselves.

If there's anything I should add or update on this post (especially broken links), please send me a private message—I may not notice a comment on the post.
Finally, a big thank you to everyone that helped write this post via its predecessors!
I think there's also definitely a prestige/coolness factor which isn't correlated with difficulty, applicability, or usefulness of the field.
Quantum mechanics is esoteric and alien and weird and COOL and saying you understand it whilst sliding your glasses down your nose makes you into Supergeek. Saying "I understand how wet stuff splashes" is not really so... high status. It's the same thing that makes astrophysics higher status than microbiology even though the latter is probably more useful and saves more lives / helps more people - rockets spew fire and go to the moon, bacteria cells in a petri dish are just kind of icky and slimy. I am quite certain that, if you are smart enough to go for any field you want, there is a definite motivation / social pressure to select a "cool" subject involving rockets and quarks and lasers, rather than a less cool subject involving water and cells or... god forbid... political arguments.
And, hmm, actually, not quite true on the last point - a social scientist could develop an intervention program, like a youth education program, that decreases crime or increases youth achievement/engagement, and it would probably feel awesome and warm and fuzzy to talk to the youths whose lives were improved by it. So you could certainly get closer than "developing some successful self-help book". It is certainly harder, though, I think, and there's certainly a higher rate of failure for crime-preventing youth education programs than for modern bridge-building efforts.
To be honest, I found QM to be the least interesting subject of all physics which I've learned about.
Also, I don't think the features you highlighted work either. Fluid dynamics has loads of counterintuitive findings, perhaps even more so than QM, e.g., streamlining can increase drag at low Reynolds numbers, increasing speed can decrease drag in certain situations ("drag crisis"). Fluids also has plenty of esoteric concepts; very few people reading the previous sentence likely know what... (read more)
