What constructive mathematicians know is that there are mathematical universes in which sets are like topological spaces and properties are like open sets. In fact, these universes are well-known to classical mathematicians (they are called toposes), but they look at them from “the outside”. When we consider what mathematicians who live in such a universe see, we discover many fascinating kinds of mathematics, which tend to be constructive. The universe of classical mathematics is special because in it all sets are like discrete topological spaces. In fact, one way of understanding LEM is “all spaces/sets are discrete”. Is this really such a smart thing to assume? If for no other reason, LEM should be abandoned because it is quite customary to consider “continuous” and “discrete” domains in applications in computer science and physics. So what gives mathematicians the idea that all domains are discrete?
His depersonalization causes a great deal of stress as he searches for an authentic personal identity.
BT has also been prevented from holding a majority share of a telepoint operator.
The Turks have a drink called coffa (for they use no wine), so named of a berry as black as soot, and as bitter[…], which they sip still of, and sup as warm as they can suffer[…].
