I've been working on this episode for some time and am pleased to finally release it. Enjoy the evolutionary history of animals!

A journey through the evolutionary history of animals, beginning with the split of the metazoans from protists about 760 million years ago and ending with the rise of the amniotes about 340 million years ago. The focus is the development of key morphological traits necessary for more complex animal....

Part 2 of quantum electrodynamics is now available. Enjoy!

Continuing from quantum electrodynamics part 1, here we explore the mathematical machinery used to compute interactions between particles, including propagators, Feynman diagrams, cross sections. We then walk through a simple example calculation to illustrate how these tools are applied. I conclude....

Our next exciting episode is the first of a two-part series in which we do a deep dive into quantum electrodynamics. Enjoy!

A detailed look into the physics and mathematics of quantum electrodynamics, the theory of how light and matter interact. We discuss the generalisation of the Schrodinger equation to the Klein-Gordon and Dirac equations, and howw these describe the propogation of light and fermions respectively. We....

Hi all! If any if you follow my personal page, you may know that I recently had an accident and was in hospital for about a week. I'm doing well and am on the mend now, but this caused a delay in the release of the next episode. However your patience has been rewarded, and now I'm happy to release Episode 157: The Geologic Time Scale. I've been wanting to do this one for years, so I'm excited to finally get it out. Enjoy!

A survey of the Earth's history through the lens of the geologic timescale. We begin with a discussion of the terminology of geochronologic units and how they are specified using 'golden spikes'. We then review the development of Earth's atmosphere, geosphere, and biosphere through the Hadean, Arche...

New episode up on fossils and dating. Enjoy!

An introduction to the techniques used to study the history and ages of geological speciments. We begin with an overview of chronostratigraphy, covering principles of relative dating, way up indicators, and biostratigraphy. We then discuss geochronology, including a review of early attempts to deter...

New episode up on embryology. This material is going to be very important going ahead for our series on the evolutionary history of life, so I recommend taking a listen. Hope you enjoy!

An introduction to the process of development, beginning with fertilisation and covering the stages of blastocyst formation, implantation into the uterus, gastrulation and its constituent cell movements, neurulation and the role of the notochord, and the beginnings of organogenesis. We also discuss....

There's been a longer break than usual as I've been busy finishing up my PhD and moving to the US. Now you can finally enjoy this episode I've been working on for some time. Hope you like it!

An overview of Magnetic Resonance Imaging (MRI), beginning from the basic physics of nuclear magnetic resonance, and covering the use of radiowaves to excite nuclear spin states, and the T1 and T2 modes of relaxation. We then explore how these phenomena are used to produce 3d images, including magne...

We finally conclude our dietary series with a look at low carb vs low fat diets. A controversial topic - hope you enjoy!

A review of the carbohydrate insulin model of obesity and the related proposal that low carbohydrate diets are superior to traditional low fat diets. I begin with a discussion of the theory behind the carbohydrate insulin model, and then assess its plausibility using relevant evidence from rodent st...

Enjoy a special episode, in which I discuss brain preservation, mind uploading, and the end of death with my friend Dr Ariel Zeleznikow-Johnston.

An interview with Ariel Zeleznikow-Johnston, author of the book 'The Future Loves You: How and Why We Should Abolish Death'. We begin by discussing how best to define death, focusing on the idea of death as the permanent disruption of psychological identity, and how such identity is constituted by o...

The next episode in our series on nutrition and health is finally ready. This one was particularly difficult to prepare for, but I hope it is worth the wait.

A review of the science between the metabolic syndrome, including discussion of obesity, diabetes, hypertension, and hyperlipidemia. We discuss the pathophysiology of how enlargement of adipocytes disrupts metabolic signalling pathways and leads to buildup of lipid intermediates. We then consider ho...

Hi all, hope your new year has been going well. The most recent episode was published earlier this month but I neglected to link it, so here it is. Enjoy!

An introduction to human nutrition, in which we discuss the nutritional importance and role of carbohydrates, fats, proteins, vitamins, and minerals, before considering the effects of malnutrition, how it is measured, and its prevalence around the world. We conclude with an analysis of basal metabol...
