Florida State University has put up a very interesting Java applet on its Web site. It begins as a view of the Milky Way Galaxy viewed from a distance of 10 million light years and then zooms in towards Earth in powers of ten of distance -10 million, to one million, to 100,000 light years, etc., until it finally reaches a large oak tree leaf. But that is not all. It zooms into the leaf until it reaches to the level of the quarks viewed at 100 attometers.

I didn't write any of the above, so don't ask me what an attometer is. Also, there are various kinds of oak trees in this world, and the one pictured has leaves that look nothing like the leaves on the oak tree in my back yard. I never realized before that the leaves from oak to oak were that different. So I took a trip to Google Images to check it out.
Imagine just a few minutes with the site and I'm already doing some "research." This should be a good site for aue'ers, the generally curious, and most kids, I would think.

There's a lot more at this site than what is described above. (If this URL was posted in aue before, I don't remember it. So maybe it's new...?)
Enjoy.
