Constructor Quote by Eric Freeman
““Math is not a constructor, or even a function. It’s an object. As you know, Math is a built-in object that you can use to do things like get the value of pi (with Math.PI) or generate a random number (with Math.random). Think of Math as just like an object literal that has a bunch of useful properties and methods in it, built-in for you to use whenever you write JavaScript code. It just happens to have a capital first letter to let you know that it’s built-in to JavaScript.””

![“Besides language and music, it [mathematics] is one of the primary manifestations of the free creative power of the human mind, and it is the universal organ for world understanding through theoretical construction. Mathematics must therefore remain an essential element of the knowledge and…” quote by Hermann Weyl](https://sms4smile.com/quotes/img-quotes/48e/hermann-weyl-16709_ability_besides-language-and-music-it-mathematic_2408893.jpg)
