Are you nervous when you see NCWEE? concerned when you see CIRC? perturbed when you see PBC? Visit Mr. Hansen’s fabled abbreviations page to make sense of those cryptic markings you see on your papers.


Schedule at a Glance (see archives for older entries)
Written assignments should follow the HW guidelines.


F 5/18/012

Field trip to the National Cryptologic Museum, Fort Meade, MD (adjacent to the NSA parking lot). We will leave at 8:00 a.m. sharp from the service road near the Martin Gym.


During the bus ride to and from Fort Meade, you may remove your blazer if you wish.

If you attend the field trip, you are excused from A-F period classes. If you cannot attend the field trip, then you must attend all classes as usual and write up problems 1 through 5 from the Mathematical Scavenger Hunt. In that case, your paper will be collected on Monday.


M 5/21/012

No class.


T 5/22/012

HW due (only for those who did not attend the field trip): problems 1 through 5 from the Scavenger Hunt.


W 5/23/012

HW due: Read Chapter 7 (pp. 125-150) of Painting with Numbers. Reading notes are required, as always. Reading notes may be collected. Copying of reading notes is not permitted. Violators may be sent to the honor council. If you are unable to finish the reading, then do as much as you can, and keep a time log.


Th 5/24/012

HW due: Finish Chapter 7 (pp. 125-150) and start reading Chapter 10. Reading notes are required. Reading notes may be collected. Copying of reading notes is not permitted. Violators may be sent to the honor council.

Philosophical Links:
-- In praise of Bayes: a very readable overview of the tension between the standard (“frequentist”) approach to probability and the Bayesian view

Controversial Links:
-- Does an elite college really pay? Article addresses the issue of whether you would do better financially if you simply invested the difference in tuition price.
-- Does traditional hypothesis testing actually make sense? Article questions whether the entire second semester of our course is a waste of time . . .
-- Are law schools cooking their ranking statistics? Every high school statistics student should read this (and maybe a second time, four years later).
