Looks pretty good!

I downloaded a set of math lectures to brush up.
But regarding the "dumbing down of education", there's a bit more to it than simply "getting educated" - we need the right education on the right topics. Probably the most important single topic is "critical thinking" in the classical sense, i.e. argumentation theory, informal logic, formal logic, etc. These form the basis of philosophy, math, physics, and pretty much every other discipline (in the classical sense, and not the modern, bastardized versions). It is from these that we get goodies like the scientific method. (Thumbs up to Karl Popper for a lot of good work there.) e.g. Being indoctrinated by a history course doesn't really help much, but being able to sort through the skewed account and ask pointed questions that expose the bias is an excellent skill to have, and probably only available to those that have more a classical education.
The problem of... ooops... I'm really getting off topic here, and that should be in the other thread...
Anyways...
I find that there are a lot of fantastic materials out there from non-traditional sources, i.e. not universities, schools, or "educational institutions". Often you need to sort through a lot of the materials, and take some with a grain of salt, but they are out there.
Here are a few examples (mostly video as I prefer videos to relax - yes education is relaxing for me - primarily because I read in excruciating detail all day):
http://theurbanfarmingguys.com/Some great little videos there for things like how to make laundry soap for $0.20 a gallon, or how to make a $4,000 vortex filter for under $100. While few people need a vortex filter, I rather doubt there are many people here at DC that couldn't use the information on how to make laundry soap, especially as you'll pay $5 or more for a gallon, i.e. 25x as much. Pretty useful I'd say.
http://www.thunderbolts.info/A very good film with a lot of information on an alternate view of physics and cosmology. Check for the video on YouTube to watch it.
The Big Bang Never Happened:
http://www.youtube.c...eature=youtube_gdataJust an example of some scientists (astronomers) that walk through evidence that contradicts mainstream science/cosmology. (Gets into red shift a lot and has some really interesting stuff in it.)
Abortion: Black Genocide in 21st Century America
http://www.maafa21.com/https://www.youtube..../watch?v=3B2YG7vtwXAWalks through a lot of history that never seemed to make it into any history classes in any school I've ever heard of. (Highly recommended.)
Open Source Ecology
The Global Village Construction Kit
http://opensourceecology.org/Some really cool stuff happening there, though it is all very practical, and not theoretical. However, if you wanted to contribute, you would have to know quite a bite of theory.
Khan Academy
http://www.khanacademy.org/Mostly traditional topics, but a lot of very good materials there. I brushed up on some vector math there a while back. Helped to refresh my mind on cross and dot products. As a random lesson, this might be fun for some people: Why dividing by zero is undefined -

(I'm quite sure it will be
above the heads of anyone involved in monetary policy in Australia, Canada, Sweden, and New Zealand.)
Another more or less random video lecture:
Blackhat 2010 - Extreme-Range RFID
http://www.youtube.c.../watch?v=c2jjciETUdIGreat treatment of RFID and how to steal credit card numbers from everyone within a given radius of you. Recommended viewing for anyone remotely interested in just how easily some financial security measures are defeated in the real world.
The number of fantastically, mind-numbingly, stupendous materials available out there just boggles the mind. But you can find them all over the place, and limiting oneself to "educational" sites cuts down on the possibilities drastically.
Most of the examples I have above are meant to spur on more questions, and for anyone that watches them (mostly video there), they would probably have more questions about the topic at hand that they never would have asked in a "traditional" education setting. I find that there is great value in those things that call us to question our beliefs, be they about religion, history, science, philosophy, or whatever. We all hold false or contradictory beliefs - what makes some of us different from others is our willingness or unwillingness to change beliefs.
"It is the mark of an educated mind to be able to entertain a thought without accepting it." - Aristotle
Hmmm... As a bit of an afterthought, it would be kind of cool/fun to make an educational portal to point to a lot of these kinds of resources... Sigh... Don't have time... Still, it sounds like fun!
