Construction and Solution to an Inverse Problem Posed by Piekara's Chair: The article "'Piekara's Chair': Mechanical Model for Atomic Energy Levels" by Zofia Golab-Meyer presents a model of the real-world problem of determining classical energy states suitable for high school or undergraduate college students. This thesis combines this idea with simple geometry to demonstrate how "Piekara's Chair" may be posed and then solved as inverse problems in R2-space.
