| 0:00.0 | Professor Ashtiqar is the Eberley Professor of Physics and the Director of the Institute for Gravitational Physics and Geometry at Pennsylvania State University and is the man responsible for loop quantum cosmology. |
| 0:11.4 | Roger Penrose has described Ashtikar's approach to quantum gravity as the most important of all the attempts at quantizing general relativity. |
| 0:19.3 | I'm proud to say that this is Ashtakar's |
| 0:21.4 | podcast premiere. In this part one, we cover what was there prior to the Big Bang, the myth |
| 0:26.9 | of singularities, Buddha's parable of the poison arrow, as well as the inner versus outer world. |
| 0:33.3 | Some of the physics can be a bit esoteric, especially the technicalities of loop QG, giving a taste |
| 0:38.6 | as to what it's like to study the subject if you're interested. |
| 0:41.1 | My name's Kurtzimungle. |
| 0:42.3 | I'm a Torontoian filmmaker with a background in mathematical physics dedicated to the |
| 0:46.3 | explication of the variegated terrain of theories of everything. |
| 0:49.6 | That is, primarily from a physics perspective, but as well as investigating what role consciousness |
| 0:54.8 | has to play in the fundamental laws, provided these laws exist at all and are knowable to us. |
| 0:59.5 | If you'd like to hear more podcasts like these, then do consider going to patreon.com |
| 1:04.3 | slash kurtjimungle. |
| 1:06.3 | It's support from the patrons and the sponsors that allow me to do this, to put out podcasts of this quality, |
| 1:11.7 | of this length consistently, as this is now what I'm able to do full time. Today's sponsor is |
| 1:16.1 | Brilliant. Brilliant is a place to learn mathematics, science, and engineering in an interactive |
| 1:20.2 | form. Soon I would like to speak to Chiara Marletto on information theory, so I decided to take |
| 1:25.1 | Brilliant's course on random variable distributions and information theory, and after taking that course, I could finally see why entropy is defined the way it is. There are plenty of other different courses. You can even learn group theory, which is what's being referred to when you hear that the standard model, the internal gauge groups of the standard model are contingent on U1, cross-su2, cross-su3. Visit brilliance.org slash toe, that is T-O-E, to get 20% off the annual subscription. And I personally, I recommend that you don't stop before four lessons. I think you'll be greatly surprised at the ease at which you can now comprehend subjects you previously had a difficult time grocking. All right. Now, part two will be in a few months, |
| 2:01.6 | so note your questions down in the comments for me to ask the professor. |
| 2:04.8 | Thank you and enjoy part one with the great Abai Ashtakar, |
| 2:09.3 | making his podcast premiere on the Toe Channel. |
