Excellent intro by PatrickD. I tried to improve it further.--Andy Schlafly 22:57, 31 October 2009 (EDT)
- I realize that reverting the site owner is not to be taken lightly. I moved your stuff down lower, because the term "scalar" hadn't been defined yet. Also, I didn't agree with your notion that the derivative of the temperature is a vector. Then I realized that you are referring to the gradient. However, I think that discussion of the gradient is premature this early in the introduction to vectors. We need a better connection to gradients (and vector dot products and cross products, of course) later in the article. I don't know just how this should be done. But at this early point in the article, I think that what I wrote is close to the right thing.
- You should take my recent change in the spirit of "How about this as proposed improvement?", not as "I reverted you." It just seemed that editing my proposed changes into the article was simpler than making sandbox articles or extensive discussion here on the talk page. Please feel free to improve!!!

- Your improvement to my edit is excellent. It's an example of utilizing the potential of a wiki. I wouldn't revert your change; your improvements are what make the result better for readers and students.
- I've found that in math and science and economics, it really makes a huge difference how clearly something is taught, particularly for the average or below-average student. Many of these concepts are understandable by all, if presented in an optimal way. That's our goal. Your work is particularly clear in explaining complex material.--Andy Schlafly 23:34, 31 October 2009 (EDT)
- If your goal is to teach students about this stuff, then I don't think an encyclopedia is the ideal format for that. Since each encyclopedia article must be concise and complete, there's no room for exercises, tutorials, detailed examples, lengthy explanations, explanations in different levels, etc. Maybe a project similiar to Wikipedia's Wikibooks should be used.
