Let’s start with what Khan Academy is. Khan Academy is a collection of video lectures that give demonstrations of mechanical processes. When it comes to this purpose, KA videos are, on the average, pretty good. Sal Khan is the main reason; he is approachable and has a knack for making mechanical processes seem understandable. Of course, his videos are not perfect. He tends to ramble a lot and get sidetracked; he doesn’t use visuals as effectively as he could; he’s often sloppy and sometimes downright wrong with his math; and he sometimes omits topics from his subjects that really need to be there (LU decomposition in linear algebra, for example). But on balance, KA is a great resource for the niche in which it was designed to work: giving demonstrations of mechanical processes.

But let’s also be honest about what Khan Academy is not. Khan Academy is not a substitute for an actual course of study in mathematics. It is not a substitute for a live teacher. And it is not a coherent curriculum of study that engages students at all the cognitive levels at which they need to be engaged. It’s OK that it’s not these things. We don’t walk into a Mexican restaurant and fault it for not serving spaghetti. I don’t fault Khan Academy for not being a complete educational resource, because it wasn’t designed for that purpose. Again, Khan Academy is a great resource for the niche in which it was designed to work. But when you try to extend it out of that niche — as Bill Gates and others would very much like to do — all kinds of things go wrong.

When we say that someone has “learned” a subject, we typically mean that they have shown evidence of mastery not only of basic cognitive processes like factual recall and working mechanical exercises but also higher-level tasks like applying concepts to new problems and judging between two equivalent concepts. A student learning calculus, for instance, needs to demonstrate that s/he can do things like take derivatives of polynomials and use the Chain Rule. But if this is all they can demonstrate, then it’s stretching it to say that the student has “learned calculus”, because calculus is a lot more than just executing mechanical processes correctly and quickly. To say that it is not — that knowledge of calculus consists in the ability to perform algorithmic processes quickly and accurately — is to adopt an impoverished definition of the subject that renders a great intellectual pursuit into a collection of party tricks.

Students should never use information in Wikipedia (or any other online encyclopedia) for formal purposes (such as school essays) until they have verified and evaluated the information based on external sources. For this reason, Wikipedia, like any encyclopedia, is a great starting place for research but not always a great ending place.

It is possible for a given Wikipedia article to be biased, outdated, or factually incorrect. This is true of any resource. One should always double-check the accuracy of important facts, regardless of the source. In general, popular Wikipedia articles are more accurate than ones that receive little traffic, because they are read more often and therefore any errors are corrected in a more timely fashion. Wikipedia articles may also suffer from issues such as Western bias, but hopefully this will also improve with time. For more information

Although the majority of edits attempt to improve the encyclopedia, vandalism is frequent.

AbstractNormal subjects and patients with adult-onset diabetes received 10 gm. of aspirin in four days. On the fourth day, the fasting serum glucose and the glucose response to oral glucose were decreased in both groups. These changes were associated with increased levels of serum insulin and pancreatic glucagon, although the glucagon responses to oral glucose were unchanged. In the diabetic patients, aspirin therapy was followed by a decreased glucose response to I.V. glucose and by the appearance of an early insulin peak, which could not be demonstrated before treatment. Aspirin did not affect the I.V. glucose tolerance in normal subjects, although it did enhance the early insulin peak. A decrease in the fasting levels of free fatty acids was noted in both groups, whereas the fasting level of triglycerides decreased only in the diabetic patients. Cholesterolemia did not change in either group. A few preliminary observations indicate that, in normal subjects, ibuprofen and ketoprofen, two other presumed prostaglandin inhibitors, did not affect fasting glycemia, glucose tolerance, or the insulin response to glucose. No changes were noted after the administration of placebo.

I wonder if they did that to make sure they had a response and if there is a break point of some lower dose. I am on 325 once a day now. Been that high in the past for other things, lots of ringing in the ears when you get that high of a dose.

The therory is that it helps to regenerate the once turned off Beta cells, not over working the exiting ones. This is just one article I found, they are many, most of them concern Salsalate a drug used for arthritis. It works by lowering the inflammation of the liver and pancreas. Lowers IR, its a pretty interesting concept based largerly on inflammation of one muscles and organs. Originally Posted by jeanne wagner i know for heart health they recommend the baby 81 mg a day. I would think you wouldn't have a stomach lining left if you took that on a daily basis. Also just because it stimulates insulin doesn't mean it is a good thing. Sulfonyureas also overstimulate insulin and there is some thought they lead to beta cell burnout. I think it is better to find things like metformin that make you more sensitive to the insulin you naturally make.

I say in this interview that the only way we can learn is by doing and to do that we must practice constantly. Schools rarely teach doing, mostly teaching abstract theories that will never matter to 99% of the population.

So, my advice. Know what matters to you. Learn that. Temporarily memorize nonsense if you want to graduate but have a proper perspective on it. Nothing you learn in high school will matter in your future life.
