Perpetuity Science: In order to understand finance, one should first understand the nature of the perpetuity, which is the basis for finance. Finance is the set of concepts, methodologies, and optimization models associated with the perpetuity. The perpetuity can be modeled with the following formula: Perpetuity value = CF / r Where CF represents the benefit stream associated with the perpetuity and r represents the discount rate associated with the perpetuity’s risk of receiving the benefit stream. All finance content can be broken down in relation to the perpetuity, namely: Build-side – the building of perpetuities (entrepreneurs, corporations) Sell-side – the selling of perpetuities (investment bankers, wall street) Buy-side – the buying of perpetuities (private equity, corporate M&A)
