There is something to be said to improving the quality of life as well as saving lives. In scientific and discovery fields such as pure math, contributions could improve the quality of life exponentially.

Does anyone have any unbiased statistics on gender in workforce, career choice, education, and any other relevant statistics?

This reminds me of the surprisingly accurate approximation of pi x 10^7 seconds in a year.

This chart has been extremely helpful to me in school and is full of weird approximation like the two above.

Thank you.

Yes that is what I was implying and you seem to have been successful in deriving that so I don't really see the point in suggesting that I should have explained it differently.

I also would like to point out that Anthony didn't disagree with me when i said it and accepted that assumption. When I can i'm going to use the arguments that Qiaochu_Yuan had and go back to talk with him to see if he will update as well.

I don't think it works on all inconsistency though just large one's. There is a large mass difference between a box with nothing in it and a box with something in it. This doesn't necessarily work for lets say a box with a cat in it and a box with a dead cat in it.

May I ask why the downvotes if I promise not to rebbutle and suck up time?

Finding such videos without discovering the truth inadvertently seems difficult. Do you have links to share?

I don't have them any longer. An easy way to do it is have a friend pick out videos for you (or have someone post links to videos here and have someone pm them for the answer). Or while on YouTube look for names that you've heard before but not quite remember clearly which is not really reliable but its better then nothing.

In the short story/paper "Sylvan's Box" by Graham Priest the author tries to argue that it's possible to talk meaningfully about a story with internally inconsistent elements. However, I realized afterward that if one truly was in possession of a box that was simultaneously empty and not empty there would be no way to keep the inconsistency from leaking out. Even if the box was tightly closed it would both bend spacetime according to its empty weight and also bend spacetime according to its un-empty weight. Opening the box would cause photons and air molecules (at the least) to being interacting and not interacting with the contents. Eventually a hurricane would form and not form over the Atlantic due to the air currents caused (and not caused) by removing the lid. In my opinion If there is any meaning to be found in a physical interpretation of the story it's that inconsistency everywhere would explode from any interaction with an initial inconsistency, probably fairly rapidly (at least as fast as the speed of sound).

I'd be interested to know what other people think of the physical ramifications.

I've been reading the sequences but i've realized that less of it has sunk in then i would have hoped. What is the best way to make the lessons sink in?

I've been trying to correct my posture lately. Anyone have thoughts or advice on this?

Some things:

  • Advice from reddit; if you spend lots of time hunched over books or computers, this looks useful and here are pictures of stretches.

  • You can buy posture braces for like $15-$50. I couldn't find anything useful about their efficacy in my 5 minutes of searching, other than someone credible-sounding saying that they'd weaken your posture muscles (sounds reasonable) and one should thus do stretches instead.

  • Searching a certain blog, I found this which says that sitting at a 135-degree angle is better than sitting straight, and both are better than slouching. Elsewhere on the internet, some qualified person said that standing is better than all three.

  • At the moment I'm not sure that good-looking posture is healthier, but I'd guess it's worth it anyway because of signalling benefits. My current best guess for how to improve things is to use a standing desk and to give some form of reinforcement when I notice and correct my posture. And to sit as little as possible, and not in chairs. I may incorporate stretching, but only a little and in parallel with another activity because 15 minutes a day for like 3 months is a lot of time.

I could spend more time trying to figure this out, but I suspect others here might have already done that. If so, I'd be super happy if you'd post your conclusions, even if you don't take the time to say how you came to them.

I found that going to the gym for about half an hour a day improved my posture. Whether this is from increased muscles that help with posture or simply with increased self-esteem I do not know but it definitely helped.

From the Wikipedia article on CAPTCHAs:

 Several research projects have broken real world CAPTCHAs ...

That strikes me as one of the least beneficial research projects that I have ever heard of. I really hope they didn't publish their methods freely.

I would hope that they did. The immediate benefit of such research is that it will show which features of CAPTCHAs are really easy to circumvent, and therefore it will help people to build stronger CAPTCHAs, and thus to keep out more spammers.

Side benefits in fields such as image recognition are also probable.

also this xkcd comic seems very on topic
