Jacobs School Seniors Bring Engineering Talent to a Hands-on Physics Course
"I would heartily recommend this course to other engineering students," said ECE's Wang. "The emphasis on having the students choose the project under basic guidelines provides more room for creativity and innovation than the average course."
Not every engineering senior can get into Physics 121, because they have to compete with physics seniors on their 'home turf' - and more people want to take the course than can be accommodated. During the winter quarter, only four engineering majors were enrolled and therefore eligible to participate in the annual showcase. Apart from Bhasker and Wang, the other Jacobs School of Engineering students were Puneet Khattar and Nick Comfoltey.
Physics 121 is a 10-week course divided in half. The first five weeks are dedicated to studying data acquisition and control using microprocessors. Then during the second half of the course, students break into teams which must conceive, develop, build and demonstrate a device. "Just go for it" is how Driscoll defines the overriding theme, but the devices that the students come up with must 1) detect something in the real world, 2) process the information, and 3) control something in the real world. About half of the projects use embedded microprocessors, while some use PC-scale computers, and some aren't computer-based at all.
"The class doesn't generally demand 'slick' engineering design and construction," Driscoll told This Week @UCSD's Paul Mueller. "Given the five-week time frame, it's more the excitement of trial-and-error. Actually, this seems to be how students learn best, and some projects actually are slick."
Nick Comfoltey, who is a double major in electrical engineering and physics, teamed with physics senior Constantine Karastamatis to build a laser-based rangefinder. It measures the phase-shift of an amplitude modulation at one-billionth of a second per foot.
Students voted for the best project, and three entries tied for first place. Those projects included a balancing broomstick, a magnetic levitation device, and a helium blimp piloted via a wireless Internet connection. Driscoll said that the class was "off scale" in terms of effort and success on all projects, as well as on how well the students worked together. "I am always impressed by the level of cooperation which permeates the class," he said. "We see students sharing time, designs, and even precious parts. If there is a competition here, it is truly friendly, and I see physics and engineering as one linked endeavor."
"In the days before the final presentation, students including myself would occasionally take a tour of other projects, where we were treated to an explanation of the team's recent successes and failures," said Daniel Wang. "These occurrences were a typical display of the camaraderie exhibited in the class."
