Physical Science-based Help

 

From time to time I see things being recommended on the internet that make me wonder a little.

 

As a public service, or at least to have a clear conscience, I will comment on them here.

 

I don't look for these things - I just address them as they come up.  Therefore this page is not comprehensive.  There are still a lot of things out there I have not run across yet.  I'll deal with them as I see them.

 

I also include here everyday help based on physical science.
