In the morning, we had Science Communications, where we learned how to make an effective presentation and started working on our final project slides. Then, we took a field trip to Quartus Engineering, an engineering consultant company that builds opto-mechanical designs for companies, and toured their building and workshops, saw some of the technology they made, and learned about what it was like working there.

Today we returned to lecturing, with Dr. Sahar continuing our lesson on polarization and waveplates. She explained the exponential and matrix repreentation of wave vectors, and the math behind waveplates (which can change the rotation of a polarized wave!). We walked to the structural engineering building to visit Profs. Zheng Chen’s and Ping Liu’s Labs, where we saw the equipment they used for battery restoration. After lunch, we continued working on our projects; since we obtained most of our materials, we began building our final products.

In the morning, we worked on our slides for the final project. Some groups focused on working on their poster layout and added more information, having started some work on it yesterday. In the afternoon, we continued working on building our final projects. We made progress by laser cutting, soldering, wiring, 3D printing, and making other edits in our construction.
