## Introduction

At the beginning of a lecture the lecturer will normally tell you what they are going to talk about.

Phrases they could use include:

- today’s topic/lecture
- do/talk about today

## Examples

- But
**what I want to do today**is talk some more about what determines the shapes of supply and demand curves. **What we’re going to do today**is begin with an informal discussion looking at some of Paolo’s work over the years at Goldman.- And that will be
**the focus of today’s lecture**. - So let’s get to
**today’s topic**. We’re going to finish talking about valence bond theory and hybridization. - And so
**today we’re going to turn to**the second part of the problem, which is talking about budget constraints. - And one of the key reactions
**we’ll talk about today**is the conversion of NADP. **What we’re talking about in this lecture**is cloning a piece of DNA.- OK, this is lecture eight in linear algebra, and
**this is the lecture where**we completely solve linear equations. - Okay.
**This lecture is mostly about**the idea of similar matrixes.

## Gap fill

Watch the video and complete the gaps.

- This lecture will be a some slightly shorter lecture than usual. What I first want to do is finish off the discussion of clinical psychology from last lecture and then have a little brief discussion about some very interesting research on happiness.
- And, as I mentioned, we left off and as we started back here to describe the atom and how the atom holds together the nucleus and the electron using classical mechanics. And today we’ll finish that discussion, and, of course, point out actually the failure of classical mechanics to appropriately describe what’s going on in an atom.
- The main topic today is what is a derivative.
- So we’re shifting gears today. We’re going to talk about molecular evolution, i.e., how do we understand how species evolve, how do we understand a lot about ourselves, how human evolution is taking place over the last couple hundred thousand years.
- So I think that this particular lecture, which will talk about the varied nature of Roman architecture, especially architecture commissioned by individual patrons to preserve their memory for posterity, again is particularly appropriate. I’ve called today’s lecture “Accessing Afterlife: Tombs of Roman Aristocrats, Freedmen, and Slaves”.
- But here I brought in David Swensen, who is claimed to have beaten the market consistently since 1985, and dramatically. And so, what do we make of that? That’s the subject of today’s lecture.
- Now, so what we’re going to do today is I will show you how to calculate those Fourier series. I will not be able to use it to actually solve any differential equation. It will take us pretty much all the period to show how to calculate a Fourier series.
- There’s four valves that are important and they guard the entrances. One of the key things we’re going to talk about today is the function of these valves in producing a flow.
- Today we are going to do some algorithms, back to algorithms, and we are going to use a lot of the, well, some of the simpler mathematics that we developed last class like the master theorem for solving recurrences. We are going to use this a lot. Because we are going to talk about recursive algorithms today.
- Today we’re going to hear more about the more obvious negative manifestations of white reaction to this New Negro mentality.
