A discussion of the method of reproduction of flowering plants, including an overview of the structure and function of the different components of the flower, pollination, double fertilisation, and seed formation, dispersal, and germination. I also discuss the different types of fruit and vegetables and how the different components of the plant relate to the parts that we consume. I conclude with a brief overview of non-edible plant products, including fibres, resin, and sap. Recommended prerequisite is Episode 97: Plant Structure and Function.

In this special episode I am joined by Jared Bauer, cofounder of Wisecrack, to discuss science and philosophy in movies and popular culture. We cover a range of topics including how science is portrayed in movies, how the film medium leads to science and history being presented in particular ways, and how movies and popular culture can be used as a vehicle for promoting scientific and philosophical inquiry.

In the final episode of our series on computers, I give an introduction to high-level programming languages, how they relate to assembly language and machine code, and how the compiler converts high level programs into a form that can be executed by the processor. I then outline some of the key components to high-level programming, such as data structures, control structures, and algorithms, before sketching an example implementation of a simple game. I conclude with an integrative summary of computer structure from silicon up to the operating system.

In this the fifth episode of the series 'how computers work', I begin with a summary of some of the major methods of improving the performance of the central processing unit, including pipelining, cache memory, branch prediction, and parallel processing. Following a brief introduction to assembly langague and its relationship to the machine code, I then discuss the operating system and how it interfaces with the hardware to manage program memory, system calls, input/output, and processes.
