MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_21_Thomson_Scattering_NonCollective.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So Thomson scattering-- as you remember, we set up the problem so that we had some scattering particle here. We had some incoming wave with a load of parallel wavefronts at some plane wave. It's got a wave vector Ki in the i hat direction here. We said that there was some or... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_20_Thomson_Scattering_Basics.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So today, and for the remainder of this semester, we will be discussing Thomson scattering. Please hold your applause. You won't like it. [LAUGHS] So Thomson scattering is an extremely powerful and subtle diagnostic, and it can be used over a huge range of different plasma p... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_15_Equilibria_and_Imaging.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: All right, so welcome back, been a bit of a break. You may be-- yes, exactly, why are we here? What are we doing with our lives? We're learning about plasma diagnostics. And you may remember, before we went away, we spent a very enjoyable lecture drawing all sorts of diagram... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_22_Thomson_Scattering_Collective.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So once again, we are going to be discussing current scattering.

MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_18_Neutral_Particles.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: Today, we are going to be discussing neutral particle diagnostics. So the fact of the matter is, we have some plasma, like a tokamak, and it has some block surfaces. And we want to know what's going on inside the core, because this is where the fusion is happening. In partic... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_10_Refractive_Index_Diagnostics_VI_Faraday_and_Reflectometry.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So as you remember, in the last lecture, we were looking at waves in magnetized plasma. So I'm going to give a quick recap of what we learned, and then I'm going to go on and show you how to measure magnetic fields using the Faraday effect [INAUDIBLE] plasma. So the geometry... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_13_CECE_and_Bolometry.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: Well, welcome we few, we happy few. Let's do a little recap on electron cyclotron emission, and then we will go on to a few other things. So we had a look at the physics of electron cyclotron emission. We didn't actually derive the emissivity of it, but we gave ourselves a h... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_12_Electron_Cyclotron_Emission.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So just a quick recap of what we covered on Tuesday, and then we will continue and look at electron cyclotron emission.

MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_23_Thomson_Scattering_Advanced.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: Welcome, everyone, to the final lecture. We will be discussing some of the ramifications of the collective Thomson scattering spectrum, which we derived last week. So just to remind you, we derive first of all that the scattered power into a given solid angle into a given fr... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_19_Nuclear_Diagnostics.txt | [SQUEAKING] [RUSTLING] [CLICKING] PROFESSOR: So we're very fortunate today to have Dr. Maria Gatu Johnson join us to give a guest lecture on neutron diagnostics. Maria is a principal research scientist at the PSFC. She did her PhD working on neutron spectroscopy on jet, on magnetic confinement. But now she works on ine... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_5_Refractive_Index_Diagnostics_I.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: Right, so today, we are going to start a series of several lectures on refractive index diagnostics. So these are diagnostics which use the fact that the refractive index of a plasma is not 1 in order to make measurements about the plasma. So first of all, what we're going t... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_3_Magnetics_II.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So I'm going to begin by giving a recap of the last lecture, just very briefly. And then we'll keep going with where we left off before. So you remember we talked about B-dot probes. These were little loops of wire, like this. They've got some area, A. They've got some magne... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_11_Radiation.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So today, we are starting a new topic, and we're going to be looking at radiation or self-emission from the plasmas. In a way, this is the natural language of the plasma. Previously, we have surrounded it with magnetic probes. We've plotted it with Langmuir probes. We've fir... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_9_Refractive_Index_Diagnostics_V_Abel_and_Faraday.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So we're going to go on to a slightly new topic today. We're going to be studying Abel inversion and then talking about Faraday rotation imaging. Does anyone have any questions on all the interferometry stuff we've covered so far before we leave that part alone? Everyone see... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_1_Introduction_to_Principles_of_Plasma_Diagnostics.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: Let's talk a little bit about plasma diagnostics. So this very word, diagnostic, is pretty interesting. Gnostic here is coming from knowledge, and dia is a word sort of meaning through. So these are objects that we gain knowledge through. And we're trying to gain knowledge a... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_17_Proton_Imaging.txt | [SQUEAKING] [CLICKING] [SQUEAKING] [RUSTLING] [CLICKING] PROFESSOR: So today we are going to be talking about proton radiography and proton imaging. So we're starting a series of three lectures in which we're looking at how to use particles as opposed to the plasma previously. You remember we used electromagnetic radia... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_16_Line_Broadening.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So just briefly, there was some discussion last time about Lyman sequence and the Balmer sequence and how these correspond to the K shell and the L shell. And I just looked this up, and I thought for your amusement and entertainment I would explain it. So the idea here is th... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_14_Line_Radiation.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: Right. So we talked already about free-free radiation, bremsstrahlung, electron, cyclotron radiation. We talked a little bit about free bounds or recombination radiation. And these are all relatively simple compared to the complexity of bound-bound radiation, which is what w... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_6_Refractive_Index_Diagnostics_II.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: OK, so you'll remember, in the last lecture, we discussed the technique called schlieren. And schlieren, we were relying on the fact that the plasma has refractive index gradients inside it which cause a deflection, and that deflection angle of the rays going through the pla... |
MIT_2267J_Principles_of_Plasma_Diagnostics_Fall_2023 | Lecture_8_Refractive_Index_Diagnostics_IV.txt | [SQUEAKING] [RUSTLING] [CLICKING] JACK HARE: So we talked about interferometry. We had some sort of plasma like this. And we had a probing laser beam that went through the plasma. And we split off a fraction of that probing laser beam and sent it around the plasma, which meant that when the two beams recombined, we got... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 20_Roths_theorem_III_polynomial_method_and_arithmetic_regularity.txt | YUFEI ZHAO: For the past couple lectures, we've been talking about Roth's theorem. And we showed-- so we saw a proof of Roth's theorem using Fourier analytic methods. And we saw basically the same proof but in two different settings. So two lectures ago, we saw a proof in F3 to the M And basically the same strategy, bu... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 24_Structure_of_set_addition_IV_proof_of_Freimans_theorem.txt | YUFEI ZHAO: OK. I want to begin by giving some comments regarding the Wikipedia assignment. So I sent out an email about this last night. And so first of all, thank you for your contributions to this assignment, to Wikipedia. It plays a really important role in educating a wider audience what this subject is about beca... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 25_Structure_of_set_addition_V_additive_energy_and_BalogSzemerédiGowers_theorem.txt | YUFEI ZHAO: For the past few lectures, we've been discussing the structure of set addition, and which culminated in the proof of Freiman's theorem. So this was a pretty big and central result in additive combinatorics, which gives you a complete characterization of sets with small doubling. Today, I want to look at a s... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 8_Szemerédis_graph_regularity_lemma_III_further_applications.txt | PROFESSOR: So we've been discussing Szemeredi's regularity level for the past couple of lectures. And one of the theorems that we proved was Roth's theorem, which tells us how large can a subset of 1 through N be if it has no 3-term arithmetic progressions. And I mentioned at the end of last time that we can construct ... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 1_A_bridge_between_graph_theory_and_additive_combinatorics.txt | YUFEI ZHAO: OK, let's, get started. Welcome to 18.217. So this is combinatorial theory, graph theory, and additive combinatorics. So course website is up there. So all the course information is on there. So after around the middle of the class, I'll say a bit more about various course information, administrative things... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 17_Graph_limits_IV_inequalities_between_subgraph_densities.txt | PROFESSOR: We spent the last few lectures developing the theory of graph limits. And one of the motivations I gave at the beginning of the lecture on graph limits was that there were certain graph inequalities. Specifically, if I tell you that your graph has edge density one half, what's the minimum possible C4 density... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 3_Forbidding_a_subgraph_II_complete_bipartite_subgraph.txt | YUFEI ZHAO: All right. We are going to continue our discussion of extremal graph theory. Last time, we discussed what happens when we exclude a triangle or more generally a clique. And we wish to find a graph that maximizes the number of edges. And at the end of the lecture, I stated the theorem of Erdos-Stone-Simonovi... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 7_Szemerédis_graph_regularity_lemma_II_triangle_removal_lemma.txt | PROFESSOR: I sent out a survey this morning about how the class is going, what you thought of the problem set. And I would appreciate if you provide me some feedback-- so things you like or don't like about the class or about the problem set that was just due last night. So I can try to adjust to make it more interesti... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 11_Pseudorandom_graphs_I_quasirandomness.txt | PROFESSOR: So we spent the last few lectures discussing Szemerédi's regularity lemma. So we saw that this is an important tool with important applications, allowing you to do things like a proof of Roth's theorem via graph theory. One of the concepts that came up when we were discussing the statement of Szemerédi's reg... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 13_Sparse_regularity_and_the_GreenTao_theorem.txt | YUFEI ZHAO: Last time, we considered the relationship between pseudo-random graphs and their eigenvalues. And the main message is that the smaller your second largest eigenvalue is, the more pseudo-random a graph is. In particular, we were looking at this class of graphs that are d-regular-- they are somewhat easier to... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 6_Szemerédis_graph_regularity_lemma_I_statement_and_proof.txt | YUFEI ZHAO: We're about to embark on a new chapter in this course where I want to tell you about Szemeredi's graph regularity lemma. Szemeredi's graph regularity lemma is a very powerful tool in modern graph theory, developed back in the '70s. Today I want to show you the statement and the proof of this graph regularit... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 10_Szemerédis_graph_regularity_lemma_V_hypergraph_removal_and_spectral_proof.txt | PROFESSOR: We've been spending quite a few lectures so far discussing Szemeredi's regularity lemma, it's applications in variants of the regularity Lemma. So I want to spend one more lecture, before moving on to a different topic, to tell you about other extensions and other perspectives on Szemeredi's regularity lemma... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 2_Forbidding_a_subgraph_I_Mantels_theorem_and_Turáns_theorem.txt | YUFEI ZHAO: So the first topic that I want to discuss in this course is extremal graph theory. And in particular, there is a whole class of problems which have to do with what happens if you forbid a specific subgraph. Forbid a specific subgraph. And I ask you, what's the maximum number of edges that can appear in your... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 14_Graph_limits_I_introduction.txt | YUFEI ZHAO: So today we are going to start a new chapter on graph limits. So graph limits is a relatively new subject in graph theory. So as the name suggests, we're looking at some kind of an analytic limit of graphs, which sounds kind of like a strange idea because you think of graphs as fundamentally discrete object... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 16_Graph_limits_III_compactness_and_applications.txt | YUFEI ZHAO: So we've been discussing graph limits for a couple of lecturers now. In the first lecture on graph limits, so two lectures ago, I stated a number of main theorems. And today, we will prove these theorems using some of the tools that we developed last time, namely the regularity lemma. And also we proved thi... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 5_Forbidding_a_subgraph_IV_dependent_random_choice.txt | YUFEI ZHAO: For the last few lectures, we've been talking about the extremal problem of forbidding a complete bipartite graph. So today I want to move beyond the complete bipartite graph and look at other sparser bipartite graphs. So we'll be looking at what happens to the extremal problem if you forbid a sparse bipart... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 19_Roths_theorem_II_Fourier_analytic_proof_in_the_integers.txt | [SQUEAKING] [PAPER RUSTLING] [CLICKING] YUFEI ZHAO: Last time we started talking about Roth's theorem, and we showed a Fourier analytic proof of Roth's theorem in the finite field model. So Roth's theorem in F3 to the N. And I want to today show you how to modify that proof to work in integers. And this will be basical... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 18_Roths_theorem_I_Fourier_analytic_proof_over_finite_field.txt | YUFEI ZHAO: OK. So let's get started. So we spent quite a bit of time with graph theory in the first part of this course, and today I want to move beyond that. So we're going to talk about more central topics and additive combinatorics, starting with the Fourier analytic proof of Roth's theorem. We discussed Roth's the... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 4_Forbidding_a_subgraph_III_algebraic_constructions.txt | YUFEI ZHAO: Last time, we started discussing the extremal problem for bipartide graphs. And in particular, we saw the Kovari-Sos-Turan theorem, which tells us that if you forbid your graph from having a complete bipartide graph, Kst, then you have this upper bound on the number of edges in your graph. So we gave a proo... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 23_Structure_of_set_addition_III_Bogolyubovs_lemma_and_the_geometry_of_numbers.txt | YUFEI ZHAO: OK, we are still on our journey to proving Freiman theorem. Right? So we've been looking at some tools for analyzing sets of small doubling. And last time, we showed the following result, that if a has small doubling, then there exists a prime. It's not too much bigger than a, such that a big subset of a, o... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 12_Pseudorandom_graphs_II_second_eigenvalue.txt | YUFEI ZHAO: All right. Last time we started talking about pseudorandom graphs, and we considered this theorem of Chung, Graham, and Wilson, which, for dense graphs, gave several equivalent notions of quasi-randomness that, at least the phase values, do not appear to be all that equivalent. But they are actually-- you c... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 26_Sumproduct_problem_and_incidence_geometry.txt | YUFEI ZHAO: Today we want to look at the sum product problem. So for the past few lectures, we've been discussing the structure of sets under the addition operation. Today we're going to throw in one extra operation, so multiplication, and understand how sets behave under both addition and multiplication. And the basic... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 21_Structure_of_set_addition_I_introduction_to_Freimans_theorem.txt | YUFEI ZHAO: All right, today we're going to start a new topic an additive combinatorics. And this is a fairly central topic having to do with the structure of set addition. So the main players that we're going to be seeing in this chapter have to do with, if you start with a subset of some obedient group under addition... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 9_Szemerédis_graph_regularity_lemma_IV_induced_removal_lemma.txt | YUFEI ZHAO: We've been spending the past few lectures discussing Szemeredi's Regularity Lemma. And one of the first applications that we discussed of the Regularity Lemma is the triangle removal Lemma. So today, I want to revisit this topic and show you a strengthening of the Removal Lemma for which new regularity tech... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 15_Graph_limits_II_regularity_and_counting.txt | [SQUEAKING] PROFESSOR: Last time, we started discussing graph limits. And let me remind you some of the notions and definitions that were involved. One of the main objects in graph limits is that of a graphon, which are symmetric, measurable functions from the unit squared to the unit interval. So here, symmetric means... |
MIT_18217_Graph_Theory_and_Additive_Combinatorics_Fall_2019 | 22_Structure_of_set_addition_II_groups_of_bounded_exponent_and_modeling_lemma.txt | YUFEI ZHAO: The goal for the next few lecturers is to prove Freiman's theorem, which we discussed last time. And so we started with this tool that we proved called the Plunnecke-Ruzsa inequality, which tells us that if you have a set A now in an arbitrary abelian group, and if A has controlled doubling, it has bounded ... |
MIT_18S190_Introduction_To_Metric_Spaces_IAP_2023 | Lecture_1_Motivation_Intuition_and_Examples.txt | [SQUEAKING] [RUSTLING] [CLICKING] PAIGE BRIGHT: So welcome to 18.S190, Intro to Metric Spaces.

I like this notion of a theory of the spaces. This is a notation that Dr. Casey Rodriguez taught me, loosely spe... |
MIT_18S190_Introduction_To_Metric_Spaces_IAP_2023 | Lecture_3_Compact_Sets_in_Rⁿ.txt | [SQUEAKING] [RUSTLING] [CLICKING] PAIGE BRIGHT: So far this class, we've talked about a lot of examples which were over and over again the same three concepts. And then we talked about the general theory, which is new because it's on metric spaces, but it's very similar to the stuff we've already seen for Euclidean spa... |
MIT_18S190_Introduction_To_Metric_Spaces_IAP_2023 | Lecture_5_Complete_Metric_Spaces.txt | [SQUEAKING] [RUSTLING] [CLICKING] PAIGE BRIGHT: Let's just go ahead and get started. So as a recap of what we've been up to, the first day, we talked about what a metric space is and went through a ton of examples, which was mostly what that day was supposed to be for. The next day, we went through some of the general ... |

If those numbers don't mean anything to you right now,... |
MIT_18S190_Introduction_To_Metric_Spaces_IAP_2023 | Lecture_4_Compact_Metric_Spaces.txt | [SQUEAKING] [RUSTLING] [CLICKING] PAIGE BRIGHT: Last time we started talking about metric spaces being compact on Euclidean space in particular, where we showed on Rn that sequentially compact was the same as closed and bounded, which was the same as topologically compact. And notice that in these two theorems, we use ... |
