This is what a stripper looks like in chemical engineering

Kudos to teaching professor Justin Opatkiewicz for his Halloween costume this year. He came dressed to class as a--chemical engineering--stripper (see picture above). For those of you who are not ChemE majors, that's "a physical separation process where one or more components are removed from a liquid stream by a vapor stream. Stripping is usually carried out in either a packed or trayed column," according to Wikipedia.
Wonder how he's going to top this next year?

Halloween Pumpkin Carving--IEEE style

Nov. 3: Updated with new pictures, courtesy of UCSD IEEE and Tony Wong!

About a dozen amateur pumpkin carvers gathered Thursday evening on Warren Mall to compete in the annual IEEE Pumpkin carving contest. They could enter their oeuvres in three categories: scary, funny and IEEE spirit. Some of the entries included a dragon, the green, three-eyed aliens from "Toy Story" and a pumkin biting on another pumpkin, perhaps the most ambitious entry. After they were carved the pumpkins were illuminated from the inside using an LED circuit.
We're wondering if all that left-over pumpkin flesh will go to making pie?
