Mathematical beauty book review
(Book review this corresponds to 1.14 mathematical beauty to talk about the importance of mathematical models)
What is the mathematical model it? Mathematical model is the use of science or engineering models of mathematical logic and mathematical language construction. (Baidu Encyclopedia).
Why it is important to model, because the model building process requires accurate and precise, after the establishment of the same model to solve the problem, it can be said that the model function,
Lesson algorithm that is modeled for each question, give some input model, get some output, it is what models do. Like the Ptolemaic astronomy contribution
As defined by the language of mathematical logic, it makes the problem becomes simple exchange, the solution becomes rigorous. In the high number of classes last semester is mentioned, it is modeled on the world Section
In the study of things to do, if we will each particle included in the calculation of the world, we will be able to advance in the future, of course, this is only theoretically possible.
