On this day, I learned that I really should find something better to do with my Tuesday afternoons, although it would be nice to make that just a reading time. . .
I also learned the Wal-Mart seems to be permanently out of stock of cheap popcorn and I must needs visit Harps for my popcorny goodness.
I learned that two of my internet dragons have had their descriptions accepted, which is a big ‘In your Face!’ to the people who had critiqued them, or maybe not, but either way I like to see them there :] It also inspired me to write some more. I’m happy that I picked the theme for naming them that I did because it lends itself to describe their characters if I should prove a little barren of thought.
In more academic pursuits, I learned that the shear stress from a load on a deformation is related by a certain formula shear stress = load*cos[phi]*cos[lambda] where phi is the angle between the line of action of the load force and the normal to the plane of the deformation and lambda is the angle from the plane to the line of action of the load force. This is very convenient because the dot product formula will give you the angle in terms of cosines, so you merely need to multiply them together by the force of the load. Excellent!
