I want to set up a webcam to remotely watch my bird. (Kappa's a camera whore.) I don't have a computer located near the cage so I want this to either wirelessly connect to my Mac, or wirelessly connect to my router. I want it to automatically upload one photo every five minutes (or some other interval) to some host or other (I'm looking for recommendations there too).

Is this possible? If so, how?

This is interesting. When I learn something and when I teach something, I am very careful to use proper terminology. I don't want to learn something 'wrong' and then have to relearn it when I have a higher understanding. And I don't want people I'm teaching using colloquial terminology because it tends to lead to mistakes as concepts bleed together.

Actually, that's the thing I was most frustrated about with Number Theory at CTY. I learned the methodologies very well, and became good at thinking creatively about proofs and about mathematics in general. I did get a lot out of the course. But I don't know what the Chinese Remainder Theorem is, even though I'm fairly sure we learned it, because they had an in-joke name for it.

I mean, they had a reason for it- to show that the names were arbitrary and the mathematics were true no matter what you called it. But the fact is, there is a right name and in communicating with others you need to use the same terminology as them.

In physics I use correct terminology by default and by default I do not use any analogies. These are good students, and in their future careers I agree it is important that they know the correct terminology.

In my gen ed science classes (astro, earth and space, physical science), if it's a concept that I feel is key to the subject matter (such as isotopes or inertia) I will start with the proper terminology and the scientific explanation, and then follow up with an analogy (such as car paint jobs for isotopes, or the Couch Potato Law for the law of inertia). Students in those classes have a hard time understanding the basic concepts w/o being able to relate it to something more familiar to their every day lives. The concepts may be important to them in later life, but the *names* of the concepts will likely not be.

Wait... you compare isotopes to car paint jobs? So students mentally categorize isotopes as things that are functionally the same but look a little different?

It's an analogy that will only take you so far. Consider Carbon-14, for example. If your student hears that Carbon-14 is radioactive, will they assume that all other Carbons are radioactive, too? Adding a neutron to an element does more to it than adding a new paint job.
