We need a Terence Tao podcast.

i love listening to him, he’s a true genius

I wonder why this wasn’t recommended sooner! I enjoyed listening

I thought this podcast was dead!

I really enjoy listening Terry Tao diffrent views and deep understanding of math. Thank you😊

This was so interesting. Well done!

I loved it!!

Do somebody know a proof assistant like which Terence Tao says?

Please provide it with video

🎉

1) Calculus Foundations Contradictory: Newtonian Fluxional Calculus dx/dt = lim(Δx/Δt) as Δt->0 This expresses the derivative using the limiting ratio of finite differences Δx/Δt as Δt shrinks towards 0. However, the limit concept contains logical contradictions when extended to the infinitesimal scale. Non-Contradictory: Leibnizian Infinitesimal Calculus dx = ɛ, where ɛ is an infinitesimal dx/dt = ɛ/dt Leibniz treated the differentials dx, dt as infinite "inassignable" infinitesimal increments ɛ, rather than limits of finite ratios - thus avoiding the paradoxes of vanishing quantities. 2) Foundations of Mathematics Contradictory Paradoxes: - Russell's Paradox, Burali-Forti Paradox - Banach-Tarski "Pea Paradox" - Other Set-Theoretic Pathologies Non-Contradictory Possibilities: Algebraic Homotopy ∞-Toposes a ≃ b ⇐⇒ ∃n, Path[a,b] in ∞Grpd(n) U: ∞Töpoi → ∞Grpds (univalent universes) Reconceiving mathematical foundations as homotopy toposes structured by identifications in ∞-groupoids could resolve contradictions in an intrinsically coherent theory of "motive-like" objects/relations. 3) Foundational Paradoxes in Arithmetic Contradictory: - Russell's Paradox about sets/classes - Berry's Paradox about definability - Other set-theoretic pathologies These paradoxes revealed fundamental inconsistencies in early naive attempts to formalize arithmetic foundations. Non-Contradictory Possibility: Homotopy Type Theory / Univalent Foundations a ≃ b ⇐⇒ α : a =A b (Equivalence as paths in ∞-groupoids) Arithmetic ≃ ∞-Topos(A) (Numbers as objects in higher toposes) Representing arithmetic objects categorically as identifications in higher homotopy types and toposes avoids the self-referential paradoxes. 4) The Foundations of Arithmetic Contradictory: Peano's Axioms contain implicit circularity, while naive set theory axiomatizations lead to paradoxes like Russell's Paradox about the set of all sets that don't contain themselves. Non-Contradictory Possibility: Homotopy Type Theory / Univalent Foundations N ≃ W∞-Grpd (Natural numbers as objects in ∞-groupoids) S(n) ≃ n = n+1 (Successor is path identification) Let Z ≃ Grpd[N, Π1(S1)] (Integers from N and winding paths) Defining arithmetic objects categorically using homotopy theory and mapping into higher toposes avoids the self-referential paradoxes.

Interesting and nice. He is bit "young" and a lot rich, but yes, mathematics have to reflect reality, or stay on the ground. And would be mathematics like some wisdom?

"Yeah, no, it's been a pleasure"

wow nice 😮🫡

never listen to terence tao a 2x....

Love Math, The Secret of God is Mathematic. AL PAZA

I know this was probably a mistake but him calling MRI (31:00) medical resonance imaging is cringe for a chemist 😬

I learnt recently, that to enjoy life, you must stop asking why. Or in other words, stop asking why, and enjoy life. And here Quanta has a podcast called the "Joy of Why"? wewewew.

I was skeptical about mr. terence idea , especially in his words where if someone has this credit , then they can make some "theories" that gauge some sort of belief in it ? I think mathematics is a rigorous field , not the one based on imagination and thought ideas
