Summary

Karl Friston, a pioneering neuroscientist behind the free energy principle, joins Curt Jaimungal to discuss how this theory reshapes our understanding of brain function, Markov blankets, and the physics of perception. The conversation also examines temporal scales and the broader implications for reality.- 00:00 - Intro- 01:05 - Lecture Overview- 05:53 - Schrodinger’s Question- 08:48 - Markov Blankets (The Brain)- 16:16 - Quick Crash Course in Physics!- 29:30 - Different Temporal Scales- 35:38 - Markov Blanket (Continued)- 01:06:16 - Outro/Support TOESPONSORS:- YouTube Membership: https://www.youtube.com/channel/UCdWIQh9DGG6uhJk8eyIFl1w/join- Patreon: https://patreon.com/curtjaimungal (early access to ad-free audio episodes!)- Crypto: https://tinyurl.com/cryptoTOE- PayPal: https://tinyurl.com/paypalTOE- TOE Merch: https://tinyurl.com/TOEmerchRESOURCES:- Watch on YouTube: https://youtu.be/uk4NZorRjCo- Karl's Previous TOE Episode: https://www.youtube.com/watch?v=2v7LBABwZKA- NEW Get my 'Top 10 TOEs' PDF + Weekly Personal Updates: https://www.curtjaimungal.org- Instagram: https://www.instagram.com/theoriesofeverythingpod- TikTok: https://www.tiktok.com/@theoriesofeverything_- Twitter: https://twitter.com/TOEwithCurt- Discord Invite: https://discord.com/invite/kBcnfNVwqs- iTunes: https://podcasts.apple.com/ca/podcast/better-left-unsaid-with-curt-jaimungal/id1521758802- Pandora: https://pdora.co/33b9lfP- Spotify: https://open.spotify.com/show/4gL14b92xAErofYQA7bU4e- Subreddit r/TheoriesOfEverything: https://reddit.com/r/theoriesofeverything Theories of Everything with Curt Jaimungal features long-form, technically detailed interviews with leading researchers in physics, mathematics, consciousness, and philosophy, exploring topics at the level of active research.

0:15.4	Where was it?
0:16.8	The Royal Society?
0:17.7	It was the Royal Society.
0:19.3	It was wonderful to see you.
0:20.3	Yes, it was wonderful. You said, meet me at, where did you say? It was some statue. It was the Royal Society. It was wonderful to see you. Yes, it was wonderful.
0:21.2	You said, meet me at, where did you say? It was some statue. It was the gym. But I thought it was a pub. Yes, I remember. It was the Duke of York steps. Yes, yes. He said, meet me at the Duke of York. And I looked online, Duke of York. Oh, that's a pub. okay, it's 10 minutes away or 5 minutes away, and I'm running, and I think it was drizzling at that time.
0:40.9	Yeah, anyhow. and I looked online, Duke of York. Oh, that's a pub. Okay, it's 10 minutes away or five minutes away,

0:43.3	Why don't you start your presentation, sir? Sure. And just as context for the audience,
0:47.8	this is for a lecture series on theories of everything called Rethinking the Foundations of Biology.
0:54.4	What Lies Beyond Darwin is the question.
0:57.5	In this episode, Carl Fursten is just taking more of the rethinking the foundations of biology itself.
1:03.1	So please.
1:04.4	Thank you.
1:05.1	Indeed I am.
1:07.2	And for a reason.
1:09.6	That reason is, I'm going to appeal here to Chris Fields,
