I brought my father in as a special guest to meet Jackson. My father is a Theoretical Physicist, and has a PhD in Bio-Physics. He is known for his Jacobson Resonance, and is a very knowledgeable scientist.
During his talk with Jackson we explored, atoms, photons, fusion, Einstein's Theory of Relativity (some of the basics), and other special concepts in science. Jackson seemed to follow along with the basic conceptual idea regarding a lot of these topics. He is a very bright kid.
