The podcast discusses the role of knowledge in transforming physical reality, the nature of knowledge as explanatory and transformative, the impact of emotions and intuition on decision making, the significance of good explanations, and the connection between physics, computing, and the unpredictability of creative entities.

This is a "return to regular format" episode in one respect - readings from and reflections upon "The Fabric of Reality" but also a departure from regular formatting in another respect: I teach a bunch of simple mathematics. This is for those who might think "quantum computation" and "quantum algorithms" will be forever beyond me. They are not! I begin with (quite literally) primary school mathematics level stuff (what's a prime number, what is the "fundamental theorem of arithmetic") and very gradually move up into algebra and some modular arithmetic and present examples using real numbers of what the problem is and then lead us to a place where we can glimpse the solution (which is Shor's Algorithm). I do not promise to bring the listener to a graduate quantum physics-degree-level of proficiency in quantum information theory and cryptography - but you will gain quite some insight. I refer to the following more in-depth expositions of all this and hopefully bridge the gap I think is there between "I know a little bit of maths and physics" and the kind of thing the following more "high level" videos offer (which I present in order of increasing technical difficulty) 1. The PBS Infinite Series on all this stuff is brilliant. In particular this introduction:    • How to Break Cryp...   and this video focussed more narrowly on Shor's algorithm:    • Hacking at Quantu...   2. Here is Peter Shor himself explaining the history of his work:    • The Story of Shor...   3. Artur Ekert's graduate level free online course on Quantum Information Theory: https://www.youtube.com/@ArturEkert/v... in particular his lecture focussed on Shor's Algorithm:    • IQIS Lecture 6.9 ...   (which, aside from "The Fabric of Reality" itself, served as the basis for this episode).

This is a cross-post from my Substack podcast "The 3Rs: Reality, Reason, Rationality" the text of which can be found here: https://bretthall.substack.com/p/where-do-ideas-come-from?sd=pf#details   This diagram is also relevant:  

Science news from a "critical rational" perspective. No "believing" in explanations here, no time for instrumentalism and a focus on good explanations of the evidence. Introduction (epistemology in science): 00:00 Dark Matter: 04:32 Modified Newtonian Dynamics (MOND): 08:12 Statistical confidence in physics: 15:23 Instrumentalism in modern physics: 19:00 Fusion Power 'News': 22:09 "Spinoffs" from fusion research: 24:56 Advice for investors in pure science: 28:26 James Webb Space Telescope latest: 31:59 Concluding Remarks: 37:42

Here in this second-to-last episode on the discussion of Chapter 9 from the Fabric of Reality we discuss some of the key distinctions between the classical and quantum - the philosophical and scientific implications and then some of the current experimental approaches to (and reporting on) the actual engineering of these devices. 

This serves as "part 2" of my "Are Consciousness and Creativity the same thing?" podcast, the Youtube version of which can be found here: https://www.youtube.com/watch?v=lrjY4fR-qMU
