(2) First principles
First principles is a professional term in business email list computational physics or computational chemistry. The broad concept is related to quantum mechanics, and the narrow concept is ab initio. With some basic physical constants, the basic properties of the ground state of the system can be obtained without using empirical parameters. principle.
In recent years, first principles have become popular because of Musk's mention. The core of first principles is to go back to the origin of things to think about fundamental issues without referring to experience or other conditions. How to think about the origin. Do not deny easily, keep asking questions.
If what you want to do is without reference, or without too much experience reference, or something that no one thinks can be successful, I suggest you try to think with first principles (in fact, this situation is rare, but with Thinking about problems from first principles is a good way to exercise thinking skills).
(3) Induction and deduction
Induction and deduction are a pair of reasoning methods that are often mentioned together. Inductive reasoning is to extract general laws from many things from the individual to the general, but this general law is not completely correct (depending on whether the scope of your many things is comprehensive or not). influences).
Deductive reasoning is from general to individual (in fact, from general to general, individual to individual), you can assume a general pattern/principle, and then verify whether this pattern exists in reality.
Usually, general characteristics and conclusions are summarized from various types of information during information research and collection. When designing solutions, deductive reasoning is used to do thought experiments to obtain possible solutions.
