Benjamin Johnson's Home Page

 

Welcome to my home page.


The picture collage is still a work in progress, trying to keep things interesting. I moved my website's url to the school of information, from the math department in spring 2009. 


I taught Numerical Analysis (Math 128A) at Cal during summer 2011. A link to the 128A course materials is at the top of the page.

I will be teaching Math 16A (Analytic Geometry and Calculus) during the fall 2011 semester. I have included my course information sheet and tentative course outline below. I will be using bSpace for this course, but will try to keep the website here up to date as time permits.

- Math 16A Course Information

- Math 16A Tentative Outline

- Homework for chapter 0:
0.1 (pg 12-14): 1,7,13,23,2733,37;
0.2 (pg 20-21): 1,21,23,33,37;
0.3 (pg 25-26): 11,17,19,23,29;
0.4 (pg 32-33): 1,7,13,19,25,33;
0.5 (pg 39-40): 2,7,17,31,35,67,71;
0.6 (pg 47-50): 1,3,11,15;


Below are some links to my job application materials, the courses I have taught over the last several years, and an abbreviated list of my publications and talk slides. Feel free to email me and tell me what you think. There are links to some of my other interests in the "About Me" page linked at the top.
