An overview of the basic concepts of linear momentum, angular momentum, work and energy. Includes a discussion of the conservation of momentum, why the concept is needed, and some applications of the concept to collisions and rotating objects. The nature of energy is also discussed, along with the different forms of energy, and how the concepts of energy and work are related.

An overview of how atoms bond together to form different chemical substances, including a discussion of the tree main types of bonds (covalent, ionic and metallic), and the relationship of these bonding types to the concept of electronegativity. I also discuss the difference between polar and non-polar bonds, and conclude with some interesting applications of bonding theory to understanding the properties of materials.

An introduction to the key principles of quantum mechanics, beginning with an examination of the quantum-mechanical description of the behaviour of electrons around atomic nuclei. This is followed by an overview of some of the other major principles of quantum theory, including the Heisenberg Uncertainty Principle, the Pauli Exclusion Principle, quantum tunnelling and entanglement. The episode concludes with a discussion of alternative interpretations of these quantum phenomena. Recommended pre-listening is Episode 8: The Atom.

An examination of the atom, beginning with the origin of the concept in ancient Greece, and its subsequent development as a truly scientific idea in the 19th century. I explain the various important contributions made to the field by Thomson, Rutherford, Planck, Einstein and de Broglie, and the resultant evolution of our models of the atom.
