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