One suggestion to bring this board back to life is posting weekly
reviews or just references to some great articles. I assume a week is
reasonable timeframe for everyone to find something interesting.
Here we go: Eric Hehner "From Boolean Algebra to Unified Algebra".
One of the main article themes is the importance of notation. In particular on p.7 in the section on Symmetry and Duality Eric argues that /\ and \/ symbols are well chosen, while & and || are not!
Next, implication is a partial order relation -- couldn't agree more.
Then, there is a controversial theory of bunches. A set stripped of the boxing (err, packaging) models a nondeterminism, wow! Received on Thu Apr 12 2007 - 00:19:55 CEST
