My wonderful Mom, in love with math all her life, used to tell me that all the universe could be modeled in math. That all reason was mathematical.
Little did I know how much this very Christian woman was correct and decades ahead of her time. Bless your memory mother.
I am sure your mother was a very good person. And she seems to have been very intelligent as well. You are very lucky to have had a mother who was that thoughtful.
The man who wrote this article is not the first to theorize that everything in the universe is based on mathematics. The author mentions the Pythagoreans who lived in the ancient Greece colonies of southern Italy. They also believed all the universe was mathematics.
I also believe the physical universe and its physical processes can be modeled by mathematics. But I also think there are many aspects of the universe that mathematics cannot describe at all. Mathematics is extremely useful, but it has its limits. (No pun intended with the concept of limits in calculus.) For example, I don't think mathematics helps at all to explain love in any of its forms. Even a love of mathematics cannot be explained by mathematics.
