Consider the following infinite poset P. The elements of P are various subsets of the plane. These subsets are (a) the entire plane itself, (b) all lines in the plane, (c) all single points in the plane, and (d) the empty set. The partial order is containment. This poset is a lattice. Explain, in geometric terms, the effect of the meet and join operations in this lattice.
