The Science of Everything Podcast

An introduction to the basic concepts of biological evolution, including an overview of Charles Darwin’s contributions, a discussion of heredity, a summary of all the major evolutionary mechanisms, and a review of all the major lines of evidence supporting evolutionary theory.

An analysis of the various biases that effect the accuracy of human memory, including a discussion of spatial memory distortions, the impact of schema on memory, source monitoring failure, and the misinformation effect. I also discuss the interesting research regarding false memories, eyewitness memory, and flashbulb memories.

An overview of biochemistry, covering the basic properties, structure and functions of nucleic acids, lipids, carbohydrates and proteins. Also includes a discussion of the nature of organic molecules and the importance of carbon in living organisms. Recommended pre-listening is Episode 15: Chemical Bonding.

A discussion of the principal circumstances in which markets do not produce an optimal outcome. After formally defining market failure, I discuss the ‘big four’ market failures of market power, externalities, public goods and asymmetric information. I conclude with a brief look at transaction costs. Recommended pre-listening is Episode 12: The Price System.

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.

A discussion of the importance of the profit motive and freedom of competition in the efficient operation of a market economy. Includes an overview of the uniformity of profit principle, and an examination of how competition serves as both an opportunity and a disciplining agent for entrepreneurs and firms, thus promoting useful innovations while weeding out bad ideas.

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 introduction to basic Newtonian Physics, including a discussion of forces, velocity, acceleration, Newton’s three laws of motion, and some common misconceptions about forces. We also discuss circular motion and conclude with a brief look at the physics of walking and driving a car.

An examination of how the price system works, including an introduction to supply and demand theory, and the concepts of clearing the market and surplus maximisation. We also look at how the price system promotes efficiency helps to regulate economic activity. Also includes a discussion of how prices store and communicate economic information.
