**Formulas for Test #3:**If you need the projection operator, I will give it to you.

### Week 10

**Test #3 will be on Friday, Dec 1**. The test will cover Complex Numbers (Appendix C) and Sections 4.1 to 5.2, inclusive.- Fun link of the week: Sidney Harris Cartoons

### Week 9

**Formulas for Test #2:**If you need the projection operator, I will give it to you. If you need the rotation matrix, I will give it to you. However, it would also be fair game for me to ask you to *derive* the rotation matrix from first principles instead.- Interesting link of the week: Causes of the Space Shuttle Challenger Disaster – it's now used as a case study for engineering safety. Edward Tufte has argued that unclear communication of risk led to poor decision-making on the part of NASA. Tufte is best known for his expertise in the presentation of graphic information. For example, see his Wired article called Power Point is Evil.

### Week 5

**Test #2 will be on Friday, Nov 3**. The test will cover Sections 2.3 to 3.6, inclusive.- Fun link of the week: Patterns formed by 15 Pendulua

### Week 2

- Fun link of the week: How to be a Successful Evil Overlord

**Test #1 will be on Friday, Oct 6**. The test will cover Sections 1.1 to 2.2, inclusive, plus the Cross Product section. I will give you the formula for the projection operator.
