PH253: one more extra-credit possibility

One last chance for extra credit, the procedure is much like the last time. Due at the start of the Final exam.

1. You watch one of these lectures (about an hour each). They are very good, and aimed at a lay-audience (you are well above that, having had at least 3 physics courses so far**), and Feynman is generally very entertaining.***
2. You write me 3 page (8.5x11 in paper, 1.5 inch margins, 12pt font, single spaced) paper covering

• Two new things you learned from the lecture (or things you understood better)
• One way the lecture tied in to PH253
• One way the lecture tied in to your major/field of study
• One way the lecture tied in to everyday life

Do this, and I give you as much as +2% on your overall grade at the end of the semester, depending on quality of your writeup.* This extra credit opportunity requires a bit more writing (3 times as much, I guess), but on the other hand, the other one required you to actually attend something. I figure it about even.

To give you an idea of what 2% means:

• There will be about 10 HW sets. Each is worth about 1% of your grade. This is 2 free HW sets. Typing up a three pages should and watching a video should take a minuscule amount of time compared to two of my HW sets :-)
• Each hour exam is 30% of your grade, each question on the exam about 6%. This is like adding 3 points to your lowest exam question.

*If you are a non-native English speaker, this will be taken into account. English grammar and spelling is very silly.
**More like 'at least 2.7', since 30% of your PH253 grade is still to come ...
***Also, thanks to Bill Gates for making these lectures available ...
