What We’ve Learned from New Kind of Science Chapter 9: Fundamental Physics

In this episode of “What We’ve Learned from NKS”, Stephen Wolfram is counting down to the 20th anniversary of A New Kind of Science with [another] chapter retrospective. Read all of NKS here:

00:00 Stream Begins 2:28 Stephen begins talking 6:16 Section 1: The Problems of Physics 8:18 Section 2: The Notion of Reversibility 14:58 Section 3: Irreversibility and the Second Law of Thermodynamics 30:15 Notes 42:33 Section 4: Conserved Quantities and Continuum Phenomena 50:09 Section 5: Ultimate Models for the Universe 53:15 Section 6: The Nature of Space 54:00 Section 7: Space as a Network 57:54 Section 8: The Relationship of Space and Time 1:01:40 Section 9: Time and Causal Networks 1:06:08 Section 10: The Sequencing of Events in the Universe 1:09:00 Section 11: Uniqueness and Branching in Time 1:12:50 Section 12: Evolution of Networks 1:17:47 Section 13: Space, Time and Relativity 1:20:54 Section 14: Elementary Particles 1:22:16 Notes 1:34:06 Section 15: The Phenomenon of Gravity 1:43:22 Section 16: Quantum Phenomena 1:50:54 Wrap up of Chapter 9 1:56:30 Is measurement a time irreversible process? Is it the case that in order to gain information about a system the system must have an arrow of time? Or is the flow of time itself the generation of information? 1:57:12 Does this mean the universe is perhaps on a trajectory to reverse to it’s initial state or will the rule expand randomly forever. if the former will time run backwards or will everything that “exists” be organically destroyed in the reversal? 1:57:45 ​Is there a network defined by a few simple rules, implying that the monster group and the 6 pariah groups give rise to the Standard Model with 6 basic quarks? 1:58:30 Has anyone ever run two rules in a combined computational space, could the rules “procreate” in this instance at connecting points to combine and create new rules? 1:58:46 ​Is there any evidence of higher complexity classes of connections in regions of branchial space that are contained in finite spaces of physical space? E.g, planets 1:59:33 It seems like half integer spin particles are only observed because the universe is 3 dimensional. If your model implies that the universe is not exactly 3 dimensional, does this mean that we can observe fractional spin particles? 2:01:30 Farewell Remarks
