First principle

In philosophy and science, a first principle is a basic proposition or assumption that cannot be deduced from any other proposition or assumption. First principles in philosophy are from First Cause attitudes and taught by Aristotelians, and nuanced versions of first principles are referred to as postulates by Kantians. In mathematics, first principles are referred to as axioms or postulates. In physics and other sciences, theoretical work is said to be from first principles, or ab initio, if it starts directly at the level of established science and does not make assumptions such as empirical model and parameter fitting. "First principles thinking" consists of deriving things to their fundamental proven axioms in the given arena, before reasoning up by asking which ones are relevant to the question at hand, then cross referencing conclusions based on chosen axioms and making sure conclusions do not violate any fundamental laws. Physicists include counterintuitive concepts with reiteration. (Wikipedia).

The First Law of Thermodynamics: Internal Energy, Heat, and Work

In chemistry we talked about the first law of thermodynamics as being the law of conservation of energy, and that's one way of looking at it, but physicists like doing math more than chemists do, so let's talk about the first law in terms of an equation. You like equations by now, don't yo

Abstract: Consider a non-linear function G(Xt) where Xt is a stationary Gaussian sequence with long-range dependence. The usual reduction principle states that the partial sums of G(Xt) behave asymptotically like the partial sums of the first term in the expansion of G in Hermite polynomia
