    Fully? Hardly. Just enough to find things that engage them. Though I definitely agree high quality mentoring (not only for bright students, but in general) that can help make students aware of possibilities is something we could use more of that would be generally valuable

    but it seems it's often true that teachers in this position were happy to let kids who'd demonstrated they knew the material work quietly on something else which interested them. The whole damn point of the school system is that children and even adults DON'T learn better on their own. After all what's the point of having teachers at all if students can learn everything on their own? And yeah bright little Timmy may be able to pick up addition on his own but for calculus he may require some extra help.

    I'd argue where that's true, it's real education at its finest for everyone involved. :) Not really. What is learned is often not of much use and too unconnected to help. Children need structured teaching and need to learn in an organized manner. The opposite is how we get programmers who still use gotos and the like. Unlearning bad habits is a lot more work than learning good ones to begin with.

    My observation is that this is sometimes true, but not enough to work as a complete generalization. Often it's absolutely true that teachers or schools don't have anything else to do with these kids -- but it seems it's often true that teachers in this position were happy to let kids who'd demonstrated they knew the material work quietly on something else which interested them. There are tons of things you an do with such kids, the whole problem is that even if a teacher wants to they have no idea what to do. Furthermore the school doesn't allow them to do anything outside their own classroom.

    And especially at a secondary level, many teachers absolutely will let kids who demonstrate precocious understanding move beyond the typical sequence.. Except that guidance is needed. A lot of subjects do have a proper way of being taught without which learning them is nearly impossible.

    I agree there are some people who work like that, and I think you can beat the genuine desire to actually help people out of educators just like you can beat the desire to learn out of kids. But a genuine desire to help out is the reason a lot of educators are there in the first place. And when they no longer have a genuine desire to help students they become administrators and develop a god complex. Guess who I'm referring to as "the school" in my posts. I have gone to magnet schools and I have met exactly two administrators who actually gave a damn. One retired and the other went to work at a private school probably because he couldn't take the ego maniacal moron who replaced the other one anymore.

    ... on whether or not the gifted student is smart enough to figure out how to use resources to direct their own learning.

    The point? I think most of the smart kids -- especially if they have any kind of decent direction from parents, or a counselor, or some kind of mentor -- can take advantage of the existing system just fine, and learn to find resources outside of it to further their own goals. Kids are kids. Just because a kid is a genius doesn't make him anything other than a kid. You're expecting these kids to not only be smart but also extremely motivation and fully knowledgeable about what is possible.

    You know what they'll figure out on their own? That it takes 10 minutes to get the password of every student in the school. Why? Because it's about the most interesting thing they can do during school hours.

    How do you expect a kid to be motivated about anything when they're forced to sit for 6 hours a day in a chair and be subjected to repetitive babbling on things they learned the first time the teacher said it. Of course any attempt to claim they already know this will be returned with a "too bad, you need to stay in this class since we don't care how boring it is" response from the school. And no the school doesn't care how good the child is or how gifted they are but simply sends out the same form reply anytime someone even dares to ask to do something different.

    It's systems like that which lead to asian EE students. They're told their whole lives they have to be an EE or they'll get disowned (yes literally). Within a year of starting college they realize they hate being an EE but continue on due to the massive brainwashing they were subjected to. After two or three years they realize that they'd rather kill themselves than spend their life being an EE. By then they're however too deep into it to quit so they continue on. After they graduate they quickly choose a masters program in something that is not EE and plan to never work as one in the future. Well the smart ones at least.

    This allowed the universities to know the minimum level and rely on the expected knowledge of all the students in a given course, and there was no need for foundation years, or spending the first term or two catching everyone up. Huh? If someone needs to catch up they take more classes and if they don't need to catch up they don't. I've exempted myself from tons of required classes because they were below me and no one complained.

    Personally I'm a recent college graduate. I know statistics and CS well, majored in the former and somewhat in the later actually. I work on economics problems which necessitate a knowledge of economics. I plan to work as a consultant for biologists necessitating a strong biological knowledge.

    The basic structure of relativity guarantees that any mechanism for faster-than-light travel is also automatically a mechanism for time travel. No, certain constrained forms of FTL travel are perfectly fine from what I can tell. One method is wormholes with the property that virtual particles cause them to collapse if their arrangement hits the "can violate causality" point. As I understand it specifically no time travel is possible if there is only one FTL route (ie: the wormhole itself) between the two endpoints of a wormhole (ie: other routes can involve FTL travel but the total time it takes has to be more than any non-FTL route).

    You can also always just claim that relativity is not perfectly correct and go on from there (I think hyperspace as a universal frame of reference is the common one), nothing says it has to be perfectly right after all.

    I haven't read the book but based on the summary alone I can make a quick guess at the guys intellectual prowess. He claims from what I can tell that the current molecular system is irreducible which I don't find surprising at all for two reasons:

    a) The current molecular systems is not the one that originally evolved or the one that existed at any point in the past. Evolution removes unnecessary pieces and those pieces are quite likely the building blocks (now replaced with more efficient and specialized versions) that are essential for it to be reducible.

    b) The structure that this evolved from may be a lot different from what it is now. It may be irreducible (partially by the previous point) to anything close to its current role but its past role may have been very different. The reason or even form of the past role may be impossible to determine without knowing the exact environment that it evolved in. For example modern blood types are apparently the result of them, by pure luck, bestowing resistance to humans against certain disease (which will not exist in a million years but blood types still may in some new role).

    c) Our current knowledge of molecular biology is primitive in terms of our predictive power and is based almost fully on analysis of what we see. We cannot predict what is possible given slightly different molecules or subtle changes, we simply lack the computing power for it.

    In other words I find someone claiming that there is no evolutionary path to something a strong indication of their idiocy or irrationality. We simply do not know enough to make any such claim as we cannot predict to any degree other mitigating but now invisible factors (ie: due to c we cannot predict the possibility of a or b being the case).

    If you want to be a programmer then you need all that knowledge which in many cases only experience can bring. Now if you learn on your own, talk to people, read books, code things on your own time and look at lots of code then you don't need as much experience to teach you it all.

    If you don't want to be a "programmer" in that strict sense then that's fine as well. That's why graduate degrees and non-production coding CS jobs exist.
