The authors' main claim A simple two charge system, one charge being suspended on a spring, exhibits complex behavior including bistability, hysteresis and catastrophic response to gradual variation of the external parameters.
The compiled record
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence
A simple two charge system, one charge being suspended on a spring, exhibits complex behavior including bistability, hysteresis and catastrophic response to gradual variation of the external parameters. We discuss these complex features (that can be related, e.g., to membrane electroporation and voltage gating of ion channels) using only high school physics. Similar properties are displayed by a system comprised of magnets and springs. Using this analogy, a simple demonstration model was designed in collaboration with John Griffin, using components of the "Rogers Connections" magnetic construction toy.

Similar properties are displayed by a system comprised of magnets and springs.
