About

Exploring theoretical physics, consciousness, Ai, and philosophy in a technical manner. Visit https://curtjaimungal.substack.com for early access videos and extra writings. My name's Curt Jaimungal, a Torontonian with a degree in mathematical physics from the University of Toronto and I analyze various Theories of Everything from this analytic perspective. The separating factor of TOE from other podcasts is its focus on depth even at the risk of limiting the audience due to how much detail we delve into subjects, paralleling the intensity found in academic discourse. Theories of Everything is known for being the most technical podcast in the physics, math, and philosophy space, as its audience is geared toward academics / researchers / faculty. Contact toe [at] indiefilmTO [dot] com for business inquiries / sponsorship. Guests do not pay to appear.
