something i was pondering today just for the sake of intrigue. money is a representation, a medium if u will, of energy. in physics energy is lost when transferred through a medium, and/or when the energy is changed from 1 medium to another. the amount of energy lost is dependent on the capacities of the medium of storage, and the impedance of the medium of transfer. this loss of energy phenomenon is known as entropy. im curious on peoples opinions on the nature of entropy as it relates to money. for example, what factors define the level of impedance in the mediums of transfer? for example, is the conversion rate of energy to money an equal conversion? and what scale of measurement is/would be used for such a task?
