Welcome to version 0.5 (or so) of this-- a mere smattering of the resources.
Science is big, and there's lots of it. The most complete section is
science, simply because this page maintainer is an astronomer, but we hope
that the other sections will expand to match it.
Realize also that our aim is to provide links to the most complete site for
a given topic, the "meta-sites" that have the largest quantity of solid
information. If you happen to find (or own) a meta-site that is more
complete than what we link to, we'd love to
hear from you.
