CORE DEFINITION

Proposed by Niels Bohr, any new theory (such as quantum mechanics) must, within the domain where the old theory (such as classical mechanics) applies, yield predictions consistent with the old theory. That is, the new theory must contain the old theory as a special case.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Theory compatibility check. When learning new knowledge or innovating, it reminds us that "subversion" is not complete overthrow, but rather inclusion and transcendence of existing truths. If a new model cannot explain phenomena that the old model already explains well, it is suspect.

anchor

Anchor fast decisions

Within the valid boundary of the old theory, the new theory must reduce to the old theory, meaning their predictions agree; the old theory is an approximation of the new theory under specific limits, ensuring knowledge inheritance rather than rupture.

First Principles

In philosophy and science, a first principle (or first principles) refers to a basic proposition that cannot be deduced from any other proposition or assumption. The concept originates in philosophy from Aristotle's doctrine of the 'first cause', while in Kantian philosophy, its corresponding form is called a 'postulate'. In mathematics and formal logic, first principles manifest as 'axioms' or 'postulates', constituting the absolute starting point of logical deduction. In physics and other scientific fields, if the research process is entirely based on fundamental physical laws, without relying on empirical models or parameter fitting, it is referred to as 'from first principles' or 'ab initio'.
