It would be better if, instead of a useless albeit pretty icon, there was a brief description of what the law is about.

Fitts's Law tells me nothing about what it is other than its a UX "law" coined by someone called Fitts.

Here's a good article about this law, with many examples: http://asktog.com/columns/022DesignedToGiveFitts.html

Wasn't really about the law itself. The same applies to all laws listed.

I want to know which ones are most relevant to me. I'd like to see a summary for each one so I can make that decision before loading another page. Otherwise, I needlessly have to click on them, make a decision and click back if not.

This is similar to how a blog typically shows an excerpt for each post on the blog index. See Jakob's law.
