The set is significant both in the development of the theory of banking and in terms of documenting the history of banking in the United States. It examines the development of banking in the United States in the first half of the nineteenth century. When Congress first tried to introduce a unified currency to finance a national army it failed because of the large number of counterfeit notes in circulation. Similarly two attempts to set up a central bank resulted in bankruptcy. Even after the Mint was set up, the Federal government's theoretical monopoly over coinage did not stop states from using their charter to set up note issuing banks. The resulting corruption and fraud let to experiments in regulation and a system of "free banking." The material included examines such issues as the role of a central bank, banking regulation, banks and the money supply.

The second volume of a commonsense, self-contained introduction to the mathematics and physics of music, focusing on the digital and computational domain; essential reading for musicians, music engineers, and anyone interested in the intersection of art and science. Volume 2 of Musimathics continues the story of music engineering begun in Volume 1, focusing on the digital and computational domain. Loy goes deeper into the mathematics of music and sound, beginning with digital audio, sampling, and binary numbers, as well as complex numbers and how they simplify representation of musical signals. Chapters cover the Fourier transform, convolution, filtering, resonance, the wave equation, acoustical systems, sound synthesis, the short-time Fourier transform, and the wavelet transform. These subjects provide the theoretical underpinnings of today's music technology. The examples given are all practical problems in music and audio.
