1. "I didn't fully understand it at the time, but throughout my time as a freshman at Boston College I've realized that I have the power to alter myself for the better and broaden my perspective on life. For most of my high school experience, I was holding to antiquated thoughts that had an impact on the majority of my daily interactions. Throughout my life, growing up as a single child has affected the way am in social interactions. This was evident in high school class discussions, as I did not yet have the confidence to be talkative and participate even up until the spring term of my senior year."

1. The preservation of meets and joins, and hence whether a monotone map sustainsgenerative effects, is tightly related to the concept of a Galois connection, or moregenerally an adjunction.
2. In his work on generative effects, Adam restricts his attention to maps that preservemeets, even while they do not preserve joins. The preservation of meets implies that themapbehaves well when restricting to a subsystem, even if it can throw up surpriseswhen joining systems
3. n [Ada17], Adam thinks of monotone maps as observations. A monotone map:P!Qis a phenomenon ofPas observed byQ. He defines generative effects of such a mapto be its failure to preserve joins (or more generally, for categories, its failure topreserve colimits)
4. Example1.61.Consider the two-element setPfp;q;rgwith the discrete ordering.The setAfp;qgdoes not have a join inPbecause ifxwas a join, we would needpxandqx, and there is no such elementx.Example1.62.In any posetP, we havep_pp^pp.Example1.63.In a power set, the meet of a collection of subsets is their intersection,while the join is their union. This justifies the terminology.Example1.64.In a total order, the meet of a set is its infimum, while the join of a set isits supremum.Exercise1.65.Recall the division ordering onNfrom Example 1.29: we say thatnmifndivides perfectly intom. What is the meet of two numbers in this poset? Whatabout the join?

These are all great examples. I htink 1.65 is gcd and lcm.
