Single Idea 16170
[filed under theme 26. Natural Theory / D. Laws of Nature / 11. Against Laws of Nature
]
Full Idea
To get from a detailed factual knowledge of a situation to an equation, we must prepare the description of the situation to meet the mathematical needs of the theory.
Gist of Idea
To get from facts to equations, we need a prepared descriptions suited to mathematics

A Reaction
She is clearly on to something here, as Galileo is blatantly wrong in his claim that the book of nature is written in mathematics. Mathematics is the best we can manage in getting a grip on the chaos.
