Physics of Sound Fall 2018 Fall Projects


This fall, I taught a revised physics of sound course. The revision was due to changes to Wheaton’s core curriculum program. The course expanded from 2 to 4 credit hours. It also took on new content, since it has both a Science Practice and an Advanced Integrative Seminar tag.

For the first half of the course, the students engaged with physics of sound content in a standards based grading manner. Then, at mid-term we switched to project and seminar mode. The students devised projects and revised them twice. We tried as hard as possible to maintain a true lab-like environment, with lab meetings and everything. The students also read primary sources such as On the Sensations of Tone by Hermann von Helmholtz and Sensation and Perception in the History of Experimental Psychology by Edward Boring, as well as newer texts on psychoacoustics, which fostered discussions on how humans hear. (We found some really interesting coverage of this by Aristotle, too!)

Below are pictures of the student projects. In years past, students in my two credit hour physics of music course made projects as well, but the longer term allowed us to have more time to design, test, and refine the instruments. The students also were able to make use of the very excellent engineering lab at Wheaton.

It is interesting to me how sometimes a course will take on themes that I don’t plan for. From these projects, I believe the students and I all gained a greater appreciation for the role of resonance to make sounds louder and the challenges with the choice of materials that will enhance resonance while being easy to work with and affordable. The hardware store is a natural place for students to first look for materials, but that largely restricts them to materials like PVC. When I teach the course again next fall, we’ll focus initial design on identifying and selecting materials that will enhance resonance.


RSNA 2018


RSNA 2018 is in the books. As always, there was a dizzying array of fantastic presentations, posters, and vendors.

I presented my research in two venues:

(1) a talk in the Breast Series: Hot Topics forum in Arie Crown Theatre, seen above. The authors and title were Whitney H M, Li H, Ji Y, Edwards A, Papaioannou J, Liu P, Giger M L. “Robustness of Computer-aided Diagnosis of Breast Cancer Using Radiomics and Machine Learning Classification of 3,158 Lesions across Populations in China and the United States."

(2) a poster, coauthors and title were Ji Y,Whitney H M, Li H, Edwards A, Papaioannou J, Drukker K, Liu P, Giger M L. “Does Biopsy Influence Effectiveness of Radiomics in the Classification of Benign Lesions and Cancers on Breast MRI?"

Both of these projects were a result of the collaboration the Giger Lab has been doing with investigators from Tianjin Cancer Hospital and Institute.

Another highlight was having students in my Introduction to Medical Physics course attend the conference. The students are required to attend one “big talk” (i.e., plenary), one science session of talks, a poster session, and a vendor. It is always so interesting to read their reflections. Many are quite captivated by the dual role of science and business that is a part of the implementation of medical physics in medicine.

Finally, I want to give a shout out to my husband, who held down the fort while I was at the conference. For Chicagolanders, RSNA is the conference that is so close but yet so far away. It takes me about 1.5 hours to drive to McCormick Place each day for the conference, which is not trivial. But this year, on top of that daily drive, there was a blizzard on Sunday night. So I packed a bag for my Sunday trek over, just in case, and when the news came out about how the blizzard warning would extend into the time when I was going to present, I got a hotel room close to the conference center so I wouldn’t have to worry about getting snowed out. Meanwhile, my husband handled the overnight with a 14 hour power outage with two small kids in the house - not a trivial matter! It’s always important to give credit to what’s going on in the background to make the good things happen.


Tell your students about the 2018 Summer Fellowships from the American Association of Physicists in Medicine

The American Association of Physicists in Medicine has announced its call for applications for its 2018 summer undergraduate fellowship programs. I want to make sure as many physics professors as possible know about this offering. The announcement usually comes out a bit later than the NSF REU announcements, and so I think it can get missed.

If you have a student even marginally interested in medical physics, I hope you will let them know about the opportunity. You can click on the image above to go to a program flyer.  In addition to the program linked to in that image, there is another wonderful program, the Diversity Recruitment through Education and Mentoring (DREAM) program. Click the image below to go to the flyer for the DREAM program.

And here is a link to the full webpage. (Scroll down to get to the undergraduate fellowship information.) 

There are several nice features about the programs. The stipends are $5,000 and the ten week term can be flexible, determined by the student and the faculty sponsor. The deadline for student applications is February 2, 2018.
