Episode 40: Gun Control

The Science of Everything Podcast ·

2012/12/18

A science-based discussion of the issue of gun control in the United States. After reviewing some basic statistics about crime and gun ownership, I examine the empirical evidence concerning the relationship between gun ownership and violent crime, highlighting the many difficulties associated with such studies and the limitations of this literature. I then discuss some more specific aspects of the gun control debate, including the question of who commits most violent crimes, how deadly guns are

Episode 35: DNA Structure and Function Part 2

The Science of Everything Podcast ·

2012/07/03

Continuing on from episode 34, I discuss in detail the processes of DNA replication, transcription from DNA to RNA, and the translation of RNA to proteins.

Episode 34: DNA Structure and Function Part 1

The Science of Everything Podcast ·

2012/06/30

In part 1 of this two-part episode, I discuss the double helix shape of DNA, the structure of nucleotides, base-paring between nitrogenous bases, the genetic code, codons, DNA reading frames, the one-gene one-polypeptide hypothesis, and the Central Dogma of Molecular Biology. This basic structural knowledge will provide the basis for a more detailed discussion of the processes of DNA replication, transcription and translation in part 2 of this topic. Recommended background knowledge of episodes 10

Episode 33: Disturbing Social Psychology Experiments

The Science of Everything Podcast ·

2012/06/22

A discussion of three of the most chilling experiments in the field of social psychology: the Ash Conformity Experiment, the Stanford Prison Experiment, and the Milgram Obedience Experiment. In each case I discuss the motivation and setup of the experiment, outline the results, discuss replications and variations of the original experiment, and end with a look at the implications of the experiment for understanding the darker side of human nature.

Episode 32: Light and Optics

The Science of Everything Podcast ·

2012/04/14

A discussion of the nature of light and its interactions with matter, including a journey through the history of our understanding of light from Newton’s corpuscular theory through early wave theory and up to the modern wave-particle duality understanding. Following this is an analysis of the various ways light interacts with matter, including absorption, reflection, transmission, refraction, dispersion, and transparency.
