- Wedgwood, Seattle (Wikipedia)
Wedgwood is a middle class residential neighborhood of northeast Seattle, Washington with a modest commercial strip. Wedgwood is located about two miles (3.2 km) north, and slightly east, of the University of Washington; it is about six miles (9.7 km) northeast of Downtown. The neighborhood is further typical of Seattle neighborhoods in having more than one name and having different, overlapping, but well-documented definitions of the neighborhood.
- Boltzmann brain (Wikipedia)
The Boltzmann brain thought experiment suggests that it might be more likely for a single brain to spontaneously form in a void, complete with a memory of having existed in our universe, rather than for the entire universe to come about in the manner cosmologists think it actually did. Physicists use the Boltzmann brain thought experiment as a reductio ad absurdum argument for evaluating competing scientific theories.
