And how much space does a ring use? The final ring is more like a pinpoint, with no circumference at all. What happens? Image from Wikipedia. This was a quick example, but did you catch the key idea? We took a disc, split it up, and put the segments together in a different way. Calculus showed us that a disc and ring are intimately related: a disc is really just a bunch of rings. This is a recurring theme in calculus: Big things are made from little things.

And sometimes the little things are easier to work with. Many calculus examples are based on physics. Less than once a week, if that. You could build it out of several pipe cleaners, separate them, and straighten them into a crude triangle to see if the math really works.

But does it work in theory? Eat it. That it changed how they saw the world, as it did for him? A premature focus on rigor dissuades students and makes math hard to learn. Case in point: e is technically defined by a limit, but the intuition of growth is how it was discovered.

The natural log can be seen as an integral, or the time needed to grow. Which explanations help beginners more?

Calculus is similarly enlightening. Poetry is similar. But calculus is hard!

Arithmetic is about manipulating numbers addition, multiplication, etc. Using calculus, we can ask all sorts of questions: How does an equation grow and shrink? Accumulate over time?

Nonequilibrium Dynamics: Oscillation. Linear Algebra. Multivariable Systems. Back Matter Pages About this book Introduction From predator-prey populations in an ecosystem, to hormone regulation within the body, the natural world abounds in dynamical systems that affect us profoundly. This book develops the mathematical tools essential for students in the life sciences to describe these interacting systems and to understand and predict their behavior.

Complex feedback relations and counter-intuitive responses are common in dynamical systems in nature; this book develops the quantitative skills needed to explore these interactions. Differential equations are the natural mathematical tool for quantifying change, and are the driving force throughout this book.
