Finding Identical Packs of Skittles

One blogger has examined the probability of finding identical packs of skittles and posted their data online.

In my new lower-division mathematical modeling course (Math 42; "Introduction to Data-Driven Mathematical Modeling: Life, The Universe, and Everything"), we started our unit on discrete stochastic modeling today, so this post makes me very happy! I have, of course, e-mailed my students about this.

The Perils of Generating Functions (and Submitting a Note from a Parent with an Exam)

When I taught Math 1d, my exam instructions included a joke line that went something along the lines of "You may also use a note from your mother, though you won't need one." One student (and fellow Caltech undergrad) actually got her mother to write this note, which is fantastic (despite the threats against both Lloyd House and the Los Angeles Dodgers).

I had this posted on my door at Georgia Tech when I was a postdoc, and I found the note a year ago today when I was going through an old spiral notebook.

As a @Caltech undergraduate, I taught a probability course (Math 1d) and introduced freshmen to the glories of generating functions.

My exam instructions included a line like: "You may also use a note from your mother, though you won't need one."

Teachers Get the Last Laugh

Damn straight.

I have pulled my share of things too, of course. For example, I need to go dig old my exam instructions that allow the use of 'a note from your mother' and the question about mystery meat with Poisson-distributed things in it. (One of the students actually submitted a note from her mother. It include threats against both Lloydies and the Los Angeles Dodgers. There was also a comment about the potential health problems caused by generating functions.)
