This spacious arrangement was meant to attract a more affluent class of residents, which was achieved to some extent with a small population of doctors and entrepreneurs occupying the blocks, but rather this setup reflected the social decline of the neighborhood as a large transient population of late-coming settlers and itinerant workers contributed to a strong and continual fluctuation in the neighborhood's population.
This is usually modeled as a uniform random fluctuation between −1/2 LSB and +1/2 LSB.

Stagnation zones theorems are closely related to pre-Liouville's theorems about evaluation of solutions fluctuation, which direct consequences are the different versions of the classic Liouville theorem about conversion of the entire doubly periodic function into the identical constant.
1966 - Rainer Sachs and Arthur Michael Wolfe theoretically predict microwave background fluctuation amplitudes created by gravitational potential variations between observers and the last scattering surface (see Sachs-Wolfe effect)
In 1973, Edward Tryon proposed the zero-energy universe hypothesis: that the Universe may be a large-scale quantum-mechanical vacuum fluctuation where positive mass-energy is balanced by negative gravitational potential energy.
Edward Tryon, in the audience, was seized by an idea and blurted "Maybe the universe is a vacuum fluctuation."
