## Academic Conduct:

The UC Davis Code of Academic Conduct is here.If we knew exactly the laws of nature and the situation of the universe at the initial moment, we could predict exactly the situation of that same universe at a succeeding moment. but even if it were the case that the natural laws had no longer any secret for us, we could still only know the initial situation approximately. If that enabled us to predict the succeeding situation with the same approximation, that is all we require, and we should say that the phenomenon had been predicted, that it is governed by laws. But it is not always so; it may happen that small differences in the initial conditions produce very great ones in the final phenomena. A small error in the former will produce an enormous error in the latter. Prediction becomes impossible, and we have the fortuitous phenomenon.(Henri Poincaré, 1903)

## Midterm

A rough list of the general topics we have covered, together with the corresponding Chapters in the texts, is here.

Solutions to the midterm are here.

## Final

The final will be in our regular class room on Wed, December 12, 10:30 a.m. – 12:30 p.m.

It will cover the midterm topics plus material on bifurcation theory and maps. A rough list of the general topics together with the corresponding Chapters in the texts, is here.

Solutions to the final are here.

## Homework

Problems sets will be assigned each week on this web page, and collected in class on Friday. It's fine to collaborate with other people on the homework (in fact, I encourage it), but you should write up your own solutions.

## Grade

The course grade will be based on (weights in parentheses):

- Homework (30%)
- Midterm (30%)
- Final (40%)
