“As [Dave Sargent] awoke one morning from uneasy dreams he found himself transformed in his bed into a gigantic insect. … His numerous legs, which were pitifully thin compared to the rest of his bulk, waved helplessly before his eyes.”
- from Kafka’s Metamorphosis
After hearing Dr. Rosen’s closing lecture a few too many times, Dave is finally convinced that a beetle is in fact a better design than the human body. Lucky for Dave, the other TAs have been itching to surgically transform someone into a giant bug. Now that they have a willing candidate, they begin to formulate a plan for Dave’s metamorphosis…
1. Beetles come in a variety of shapes and sizes, so first the TAs must come up with the best design for Beetle-Dave. Specifically, Sheila wants to figure out whether Dave will be better off with six legs or eight. What can Sheila do to determine which design will be best for Dave in the long run before he goes under the knife? Explain why you chose your particular method and classify it in relation to other options. What variables might you want to take into consideration? [15 points]
2. While the TAs are feverishly preparing for the procedure at Dartmouth, Dave himself is vacationing in Las Vegas. Yet between rounds at the Blackjack table, Dave wants to remain updated about what exactly the TAs have in store for him. Will comes up with a way to keep Dave informed about the details of their design from a distance. What did Will come up with? What is he able to communicate to Dave and how? What is the value in patient education (briefly)? [15 points]
3. Meanwhile, Megan is hard at work converting Room 100 into the Operating Room of the Future to ensure that this cutting-edge procedure is a success. What does her Operating Room look like (just the “Future” parts)? How does it differ from a traditional Operating Room? How do these modifications ensure a more successful surgery? [15 points]
4. The surgery has begun. While constructing Dave’s insect legs, Sheila implants artificial extensions to his existing legs. She is concerned that the implants in Dave’s bones will come loose after a few years. Why would such implants normally dislodge? What properties are important in the material of the implants to insure that they won’t dislodge after a few years? How are these properties achieved (briefly)? [15 points]
5. Now that Dave has more legs than he is accustomed to, the TAs need to wire the new appendages into Dave’s brain. The brain is a delicate, mushy structure, and all of the parts look the same. What can Will use to ensure that he wires the new nerves to the right places without damaging the rest of Dave’s brain? Describe the components of the system and their respective functions. [15 points]
6. In order to determine the success of their endeavor post-operatively, the TAs decide to test Beetle-Dave in an Extreme Environment – a frat basement. Specifically, they want to monitor his vital signs as he encounters cute girls. What makes a frat basement an Extreme Environment? How will the TAs design their monitoring system in order to accommodate the constraints of this environment? Bear in mind that the TAs have no desire to go anywhere near the basement themselves. [15 points]
7. Is Beetle-Dave a Monster or a Marvel? Why? [10 points]
