This week we learned about conjunction, disjunction, implication, and negation. Everything we did made sense as I was able to think about it in terms of programming, with which I am more familiar. The conjunction and disjunction are exactly the same as the ‘and’ and ‘or’ which are used in almost every program. Danny put stress onto the fact that logical or is not exclusive, giving another way in which it is similar to programming. Implication to me seems simply like an if statement in programming. After looking at the truth tables from lecture, the fact that P implies Q is the same as not P or Q makes sense even though it was not immediately apparent to me. Negation made sense to me conceptually from the beginning, but I had trouble with using it in practice. As with all science courses, I was able to fully grasp how to use negation and DeMorgan’s Law after doing practice questions using it.
