This is a limited (but growing) collection of notes and resources relating to my somewhat limited (15 year) former career as an instructor of introductory engineering courses for civil engineering technologists in a two-year diploma program(me) in Canada.

And some other oddball (though conceivably educational) material that has caught my interest along the way. (Warning: I am a math nerd.)

Check back occasionally: this collection may grow on you.
