Jordan Ellenberg discusses the mathematics of high-dimensional shapes and geometries in this Lex Fridman podcast. He discusses how a two-dimensional creature could comprehend a three-dimensional world, and how mathematics can be used to explore the universe beyond our understanding. If the answer to whether extra dimensions exist is no, it would become a sterile question.

The Sphere explains that a cube would be like a three-dimensional version of the Square, while the Square is excited to finally understand what a cube would be like. However, the Sphere is unable to conceptualize that there could be yet another dimension, leading to a religious allegory that I don't really understand theologically.

**01:00:00**Jordan Ellenberg discusses the mathematics of high-dimensional shapes and geometries, noting that while he sees himself as very different from traditional researchers, his work is creating something new and powerful. He discusses the potential for computers to compete in the field of mathematics as well, pointing out that there is already a market for specialized computer algebra programs.**01:05:00**Jordan Ellenberg discusses the mathematics of high-dimensional shapes and geometries, and how difficult it can be to determine whether a knot is slice.

He also discusses the concept of distance and how it is not pre-determined by humans.**01:20:00**In this video, Jordan Ellenberg discusses the mathematics of high-dimensional shapes and geometries. He talks about the periodic distance, which is a crazy distance, and how it is important for autocomplete and machine translation. He also talks about how close two numbers need to be in order for them to be considered close. He says that two to a large power is a multiplication very small number, and two to a negative power is a very big number. He explains that binary numbers are written backwards, and that this is a good metaphor for how close two numbers need to be in order to be considered close. He says that the goal of mathematics is to help humans understand things, and that proving new theorems is one way to test that. He says that the benchmark for proving something is that it is a new theorem, but that the goal is to understand the problem rather than to know whether it is true or false.**01:25:00**Jordan Ellenberg discusses the mathematics of high-dimensional shapes and geometries. He argues that in order to understand something, we need to be able to explain it simply. He goes on to say that real things are not always simple, and that in order to understand something, we need to start with a complex idea and simplify it.**01:30:00**Jordan Ellenberg discusses the mathematics of high-dimensional shapes and geometries, and how they can be difficult to understand.

**02:00:00**According to the video, Jordan Ellenberg was a mathematician who worked on high-dimensional shapes and geometries. His research overlapped in some ways with Lex Fridman's, and Fridman would often ask Ellenberg questions in the common room. Ellenberg's responses were so rich and went so many places that they taught him a great deal about mathematics and life in general.
