HI09kat_GeI | The Biggest Ideas in the Universe: Introduction | UCRhV1rWIpm_pU19bBm_2RXw | This is an introduction to a series of videos I'm planning, informal discussions of some big idea in physics or related fields. Symmetry, space, matter, things like that. Within a few days of the release of each video, I will look over questions that have been asked, pick some of the best ones, and make a separate video to address them.
Update: yes I (now) know, the audio is only in one channel. Sorry! YouTube doesn't allow for fixes to things like that, but next time will be correct.

AeNSMJtKGc0 | The Biggest Ideas in the Universe | 1. Conservation | UCRhV1rWIpm_pU19bBm_2RXw | [Correction: at 17:51 I say kinetic energy is a vector, I meant to say "scalar." Kinetic energy has a size, but doesn't point in a direction.]
The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody.
In this installment - the very first idea we cover! - I talk about "Conservation." The idea that a certain property, like momentum or energy or electric charge, stays the same over time. In my view, realizing that this is true - and the corollary, that the world naturally moves, rather than needing something external to keep it moving - represents the real transition between pre-modern and modern physics.

Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #4, "Space." We talk about what is meant by three-dimensional space, why it might be three-dimensional, and why space exists at all. Why do we live in position space, rather than in momentum space, anyway? And what's so important about "locality"?

Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #5, "Time." We talk about what time is, whether it's "real," and about why it seems to move in just one direction. That gets us a bit into entropy, which is a teaser for a later video in the series.

Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #6, "Spacetime." Which, naturally, is about the major idea underlying special relativity -- that both space and time are different parts of one unified, four-dimensional spacetime. Learn the real reason why two twins age differently if one stays home and the other zips out near the speed of light.

Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #7, "Quantum Mechanics." We talk about the quantum recipe -- the basic ingredients of wave function and Schrödinger equation, and how they are mixed together -- leaving deeper interpretational issues for later.

This is the Q&A video associated with Idea #7, "Quantum Mechanics." Mostly it's about the double-slit experiment, and why the wave function isn't just a cheap tool for calculating probabilities. But then at the end I get into the weeds a bit talking about the sense in which quantum states form a vector space.

Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #8, "Entanglement." I talk about what entanglement means, how it showed up in classic work by Einstein, Schrödinger, and Bell, and the crucial role it plays in competing formulations of the foundations of quantum theory, including Many-Worlds and others.

This is the Q&A video associated with Idea #8, "Entanglement." Using spins as a model system, I try to explain why entanglement is much more subtle than classical correlations (as in gloves or socks). And I talk a bit more about Many Worlds and the origin of probability.

This is Idea #9, "Fields." A little bit about classical fields, but mostly concentrating on quantum field theory, and in particular on why a quantized field ends up looking like particles. This one is a bit challenging!

This is the Q&A video associated with Idea #9, "Fields."

Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #10, "Interactions." Last time we dipped a toe into quantum field theory, seeing how quantizing fields leads to particles. Now we let the particles interact with each other, and see how the results are characterized by Feynman diagrams.

Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is the Q&A video for Idea #10, "Interactions." I talk about the circumstances under which it's okay to use Feynman diagrams and think of fields as being particle-like vs. wave-like, and am a bit more precise about locality and the infinite number of degrees of freedom in a field theory.

Nm8DRUgmjZc | The Biggest Ideas in the Universe | 11. Renormalization | UCRhV1rWIpm_pU19bBm_2RXw | The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #11, "Renormalization." When you include particles in Feynman diagrams of all possible energies, you often run into infinite results, which are clearly wrong. The modern approach to this problem is to work with "Effective Field Theories," in which we admit that we only understand physics up to some cutoff energy scale. While enormously successful, this EFT paradigm also runs into issues with the Higgs mass and the cosmological constant.

1M0PJAUW9Vg | The Biggest Ideas in the Universe | Q&A 11 - Renormalization | UCRhV1rWIpm_pU19bBm_2RXw | The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is the Q&A video associated with Idea #11, "Renormalization." Mostly it is me trying to say in slightly better ways what I tried to say in the original video. But we also talk a bit about whether virtual particles are real, and whether an effective field theory of gravity can really explain all the data.

Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #12, "Scale." For something more down-to-Earth than the last couple of lectures, we think about why things have the size they do. This is a rich topic so we don't get very far into it, we'll have to return later!

Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #13, "Geometry and Topology." Yes that's two ideas, and furthermore they're from math more than from science, but we'll put them to good use. In particular we look at Riemannian (non-Euclidean) geometry, and a kind of topological invariants called "homotopy groups."

Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #14, "Symmetry." Different manifestations of symmetry are at the heart of much of modern physics, so it's worth looking at how we should best characterize it. That's leads us into the mathematics of group theory.

This is Idea #16, "Gravity." By which we mean Einstein's theory of General Relativity, according to which gravity is the curvature of spacetime. Since we've already learned about spacetime and about curvature (geometry), this one is a breeze.

This is Idea #17, "Matter." The matter of which we are made can be solid because electrons are fermions, meaning that they take up space. We talk about that and the closely related spin-statistics theorem. Complete with demonstrations using visual aids!

This is the Q&A video for Idea #18, "Atoms." A bunch of good questions this week. Why certain particles decay into other ones, can there be negative-mass particles, and how do we know there aren't noticeable forces we haven't yet discovered? There's even a plot of experimental constraints!

This is Idea #19, "Probability and Randomness." In which we accept that none of us is Laplace's Demon, and in the real world we act under conditions of incomplete information, necessitating a turn to probabilistic reasoning. We talk a bit about what that it, how it works, and how it applies to statistical mechanics.

Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #20, "Entropy and Information." The increase of entropy over time is responsible for the difference between past and future, and is thus in a very real sense the most important thing in the universe. We talk about how this works and what it has to do with the concept of information.

Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #21, "Emergence." None of us is Laplace's Demon, so how are we able to successfully model the world even though we have incomplete information about it? The answer lies in the existence of higher-level patterns that emerge in the right circumstances. Special emphasis is placed on the emergence of a classical world from quantum mechanics.

Cosmology | UCRhV1rWIpm_pU19bBm_2RXw | The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #22, " Cosmology." Perhaps more a field of study than an "idea," but it is made possible by an extremely powerful idea: that our universe is uniform and simple enough to be understandable. We go through the expansion of space, the thermal history of what makes up the universe, and a bit about dark matter and the cosmic microwave background.

This is the Q&A video for Idea #22, " Cosmology." We talk mostly about how the Friedmann equation works, and what the Big Bang really means.

__aFwrR702U | The Biggest Ideas in the Universe | 23. Criticality and Complexity | UCRhV1rWIpm_pU19bBm_2RXw | The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is Idea #23, " Criticality and Complexity." Having spend a lot of time on the basic ingredients of our universe, it's time to contemplate how they come together to make complex systems. The idea of critical behavior -- things happening at all spatial scales -- is an important organizing principle.

This is the Q&A video for Idea #23, " Criticality and Complexity." Two big themes here: the relationship between complexity and entropy, and the real-world technicalities of dealing with power-law distributions.

This is Idea #24, " Science." We bask a bit in how amazingly successful science is, wrestle with the difficult problem of *what* science exactly is, and close with some reflections on the present state and future prospects for fundamental physics.
This is the final video in the series. Thanks to everyone who has enjoyed!
