- Simple Science Explanations: Are we living in a simulation? Scientific viewThe simulation hypothesis, proposed by Nick Bostrom, suggests that advanced civilisations could create realistic simulations of conscious beings. While intriguing, science currently lacks empirical evidence to support or refute this idea. Physics describes a consistent natural universe, making the hypothesis more philosophical than scientific, with no practical implications for our reality.
- Sensors – Lecture 6: Ion-Selective Membranes and InterfacesThis lecture series on chemical sensors focuses on ion-selective electrodes (ISEs) used in various applications. It covers membrane types, Donnan and liquid junction potentials, sensor performance factors, and practical considerations. Key topics include selectivity coefficients and a real-world worked example of measuring potassium ions. Future lectures will explore catalytic gas sensors.
- Inheritance, Variation and Evolution (GCSE Biology Topic 6)This topic covers the inheritance of genetic traits, the reasons for individual variation, and the principles of evolution. Key concepts include DNA structure, reproduction methods, variation causes, natural selection, selective breeding, and genetic engineering. Understanding these elements is essential for GCSE Biology, highlighting their significance in the study of life on Earth.
