00:04 Okay. Hello everybody. My name just false a block and this is

00:09 talk meant I believe for the research class and the goal of this talk

00:16 too sharp on improve your skills of technical talks. So let's get to

00:22 topic. It is going to be underlying theme of what we're going to

00:27 today. It's not what you say a talk, but what the audience

00:32 that matters. Think of it, hear our talk and five minutes later

00:37 somebody asks you, let's say the was an hour long, what did

00:41 learn from the talk? And so, and you can describe that

00:46 just a few seconds usually. And want to people to remember the right

00:52 out of our talk, not something that you don't care about.

00:57 let's get to the basics. So this talk, I think it should

01:03 maybe 30 minutes, 45 minutes. gonna talk about a few sub topics

01:10 is the reasons for giving a how to organize it and then some

01:16 points, uh, dues and don't and then we'll conclude with that.

01:24 let's keep moving right along. some Acknowledgments. This talk is not

01:32 my own. I started off with talk by scott driscoll as Dartmouth college

01:37 I saw some years ago who himself used other sources in power berry.

01:45 , he is already university of north and uh, Bill Human. So

01:53 thing why you're giving a talk, extremely important to realize that a talk

01:59 a means to an end. There no such thing as a good talk

02:03 a bad talk. The point is you had a certain goal when you

02:08 preparing the talk, when you're giving talk was that goal achieved or

02:12 Okay, now, what would your be? Well? And of course

02:19 this, you're great depends on your . So that's a very good reason

02:24 sometimes you want to impress the audience because it has its own value,

02:28 want to be popular or you want be considered smart and brilliant. And

02:33 another very good reason. Finally, finally next, you want a

02:39 So with a PhD uh many of job interviews will include giving a

02:45 So you want to give a talk that you achieve the goal of getting

02:51 job. And finally, um research a lonely business and occasionally you get

02:59 chance to talk about it to And there is an always an a

03:04 desire to for other people to understand . You're suffering 24/7 for months,

03:12 years. And all of us want people to understand. So that's another

03:17 we're not gonna at this point, over. Uh you would do differently

03:24 each of these scenarios, but just it in the back of your mind

03:29 your goal is to achieve whatever the specific thing you're after, not just

03:37 give a talk and uh half jokingly when you go to your talk,

03:46 uh it sounds like the speaker is going to detail everything that no on

03:51 subject. And that's a really bad is never the goal in a single

03:56 . To detail a lot of And usually that one of the reasons

04:00 talk doesn't go well. And for your career, giving a good

04:06 is very important, extremely important. as important as the quality of your

04:13 . So it does make sense for to invest a little bit in developing

04:18 skills, moving on, what is talk good for and what it's not

04:25 for in a research setting. You talks, you have papers and you

04:30 one on one meetings and each of mediums is is good for some things

04:36 not the other. Here, we're to just focus on our talk.

04:40 is great for giving the context, is very important when you're talking about

04:47 research idea or your research work that done, it's extremely important and a

04:55 way for it to express it as is what's been done before, Why

05:01 your research important and what problems are open the overall context, your of

05:06 research versus what you actually did. things you can do well is an

05:13 and framework, what is the big , what does this research contribute and

05:18 methods you used to solve the So, those are the kind of

05:22 that are a big part of her ? And another thing that is unique

05:26 a talk but that you cannot do as well, at least in a

05:33 is to show your enthusiasm and You you like this work. This

05:38 a lot to you and you can that across an attack. Uh it's

05:44 it's a unique medium to be able do that. Not everything is good

05:51 a talk. Details, details, some details are necessary. We'll

05:57 We'll discuss this a little bit But generally speaking, attack is not

06:04 good way to get into too much of things and factual informations and currents

06:10 truths. So, those kind of are best left to the papers,

06:14 you do need to cover those at level in a talk to but it's

06:19 context central ideas talks as a way go details. You have to be

06:24 your men or may not get it if you just blindly include a lot

06:28 detail in the top. So now go over a structure of attack of

06:37 technical talk. So most technical talks these uh sections. Some you could

06:44 them slightly differently. Some details may different, but you typically start with

06:49 introduction then go to the main whatever it is of a talk then

06:56 go or some technical details and then conclude and that's followed up by usually

07:02 q a session. Right, So introduction. What do you

07:09 No surprises here. You define the ? What is the problem that you're

07:13 to solve, motivate the problem and audience? So you define the

07:21 Why should the audience care whether you it or not? We often overlook

07:26 you've forgotten why you were solving the because you've been working on the details

07:33 so long. But it's extremely important you define the problem and convince the

07:39 that the problem is important and doing where the audience, even though you're

07:46 starting wants to, it's for once know what has been done. What

07:51 you do? Another thing you need cover in the introduction is to discuss

07:57 state of the art, what else been done and what is not

08:01 It's extremely important, borrow speakers forget do these pieces, but it's,

08:07 introduction is very important and you need cover those and once you were done

08:13 all this, then you focus on specific contributions. You explain the key

08:21 and you provide a roadmap for the of the talk and hopefully if you

08:24 this nicely, then the audiences and to learn about the rest of the

08:32 . Next is the body, which the main content very broadly defined here

08:37 where we talk about the main experiments analysis, you list the main

08:42 and significance of the results. Sometimes see a talk where there's charts and

08:47 and whatnot, but no real good why those charts and graphs means

08:55 So the world is a better place you found those actual data or actual

09:02 , which is really not the results the significance of the results, which

09:05 a common weakness of talks. So to build those and uh at some

09:13 you would have to go into some detail. It's you know, it's

09:18 uh talk for uh for a magazine a newspaper, it is a technical

09:26 . So you have to be very here. You can present one or

09:32 key llamas or technical ideas. Don't to run through every technicalities. And

09:38 some point you may have to go details of something. And so here's

09:44 line descend into details briefly slowly and so that first that most people are

09:54 to follow you. And second, if they don't follow the detail,

09:59 they're still not like, you I have to leave now, I'm

10:02 following anything. They still get the idea. Uh this is a trade

10:08 whether to increase how much technical details include you want to keep talks at

10:15 high level so that people understand most the talk, but at the same

10:22 , especially if it's let's say its job interview you want to convince people

10:28 what you've done is not trivial. does require a lot of detailed analysis

10:34 insights and uh that's something only you a specific content you have and decide

10:42 the best way to manage these uh conflicting goals. Finally, the conclusions

10:51 here you summarize the key points and lost audience. So as you're going

10:57 the tar, it's more than likely some section of the audience has lost

11:03 despite your best attempts. So when reach the conclusions, you want to

11:09 sure that the audience still gets the home message. Yeah. So and

11:17 observations that have been confusing in the . Sometimes people ask what's the difference

11:23 abstract and conclusions? Certainly some of points in an abstract would be similar

11:29 points in the conclusions, but 11 to think about that is that what

11:37 things you can say at the end having spent Um this whatever 45 minutes

11:45 the audience that you could not have in the beginning, then those have

11:51 be there in the conclusion. Something learned and now you are distilling and

11:56 thing worse us. Something in the that was so high level that everybody

12:01 have followed anywhere very important in a , you talk about weaknesses. It's

12:10 it's a sign of strength if you able to say my work does A

12:16 and C. It cannot do the . G. H. I.

12:20 . And it's extremely helpful. It you look stronger and confident? And

12:26 just, just generally people get a better idea of what has gone on

12:31 it's always good to talk about open , you solved points to six and

12:38 , but 35 and nine are still there. Once again, that really

12:42 crystallize your work. You're in the , small piece of work in the

12:48 of the world um and gives an a good feel for what you did

12:53 . The minor points indicate that the is over. Just say thank you

12:58 said, this is this is this where it ends. I'm ready for

13:02 or something like that. Sometimes uh or just, you know, finish

13:08 and linger and then people are not if they should ask question, is

13:13 over or you just kind of So it's nice to have a chris

13:17 also, because sometimes that's the thing people remember those are the sections and

13:25 the actual content and the content is . Typically go to the Q and

13:31 section of the talk with audiences as ask questions and sometimes this is the

13:42 important part of the talk very it is very important, especially if

13:47 looking for a job. This is people are really testing you because the

13:52 target could have reversed God help and on and just put it together and

13:58 it beautifully and here is where the get to see how you react to

14:05 new situation, do you actually have depth of knowledge? Do you have

14:09 temperament to deal with an audience? just a few tips here large.

14:15 questions are really nice questions. They're requesting information, answer the best you

14:22 . And the only thing I'll add is to answer slowly and think about

14:28 , not just start talking and um, uh, then you're not

14:32 what you're talking about. So those the easy ones then sometimes, but

14:40 not all questions that you get at straightforward, You get some curveballs and

14:47 is the one where we're of course and generalizing the questioner wants to look

14:54 and knowledgeable. Okay, what's an of that kind of a question?

15:01 really starts talking about themselves and their and somehow they think that's related or

15:08 talk about some other research that they that they've heard. That sounds really

15:15 . And what do you, do hear this thing that they may or

15:18 not be correct, but you don't know too much about it. And

15:24 main thing is just very, very , be polite and complementary. So

15:30 is interesting. This seems very promising I'll look into it some more and

15:37 pay attention to that too. So only what you don't want to do

15:41 be in your face and say, , and what's that got to do

15:45 what I'm talking, right? So are important. Um, so

15:50 if you say, you know, a great point. That's excellent thinking

15:54 I'll look at it, you look at it more. But at

15:58 point I don't know enough about the to really get into a discussion with

16:03 , uh, they're happy and you're . So now here is the third

16:07 malicious questions. There may be intended may not. What's what's an example

16:15 a malicious question, you know, about it for yourself. I'm sure

16:22 heard them at different talks. So comes and says, uh, now

16:33 don't know why you're doing this research even though you had tried your best

16:40 uh, motivated and so on, you know, this, this whole

16:44 I think is irrelevant, right? another malicious question is that I don't

16:52 , I don't see anything that you're that couldn't be done with machine

16:56 right? So you're like, you , the reasons, but you don't

17:01 time with a very broad way to against all these sort of random

17:07 uh, from from nowhere. So way to deal with that is not

17:14 get into a back and forth about , you barely understand. If you

17:20 have a good answer, of course for it. But if it's just

17:25 wig and broad and uh all over place, then you don't want to

17:31 looking stupid talking about things that you know anything about. It's your

17:37 So the focus should stay on what saying, not anything anybody wants to

17:43 about. So one more time be and measured in response. Thank you

17:48 the question. That's an interesting way think about things then, um,

17:56 needed. If you don't really know question, the answer or the answer

18:00 so convoluted and complicated that even if were to deliver it, then,

18:05 know, most people won't get Standard line is, let's talk

18:09 It's perfectly fine. It's your Not the question is time to be

18:14 if it's not of interest to the audience. And finally be good at

18:20 , I don't know when somebody asked question that you do not know,

18:26 just say, I don't know, look confident, you look smart and

18:31 takes all the wind out of the . Worship You just kind of trying

18:37 talk your way out of it. start saying things midway through, you

18:41 that what you said doesn't make And then, uh, then you're

18:45 kind of, uh, ruffled and think carefully of the questions. If

18:51 have one answer. Great. If know very little about it,

18:55 I don't know none of us knows about everything. So it's perfectly

19:00 Do not know things that are not something you're around. You have actually

19:08 up in your talk finally um related these sections of introduction, body

19:19 We kind of skipped conclusions. And here it's important to remember for the

19:26 . So this is if you think it's very obvious that if you're talking

19:31 a general public, you probably want spend most of your time on introduction

19:37 the main content and very little and as you go into a more specialized

19:44 . For example, Cska Loki. , again, these are people who

19:50 computer scientists but don't know your specific . You still want to spend a

19:56 of time and introduction and body but have a little bit more on technicalities

20:04 you get closer and closer to people your kind of expertise, then you

20:10 go a little easier introduction more on body and more on technicalities. And

20:15 if you're at a focused workshop or of your type, then you go

20:21 that lighter on the introduction and spend time on the details. But one

20:28 I'd like to point out here is is always important. People uh much

20:34 often underestimate the introduction that is needed overestimate. So it's rare that you

20:41 too much time on introduction even when an expert audience, it still needs

20:46 be introduced and you still need to back into your frame of thinking before

20:52 get to the body and the All right now for the rest of

21:00 talk, we're going to talk about to do and things not to do

21:06 in many cases those would be And those would also be related to

21:11 of the things that uh that we've before. Okay. So the first

21:20 of things I would just go over in this slide and then we have

21:26 slides to go over some of the . So repeat key concepts. As

21:32 mentioned at the beginning of this when you come out of a one

21:38 talk and someone asks you what what the talk about? You usually have

21:43 , I don't know, 30 seconds 45 seconds to to save what the

21:49 was about. In fact, that's you remember. You want to make

21:53 that people remember the right thing what , some people call the take home

21:59 . So what we are doing it you repeat the same things more than

22:04 . It's perfectly reasonable uh to be be doing that. And in this

22:10 also you'll see that many key concepts been repeated in different ways and it's

22:17 that I forgot that. I already it before. It's intended If something

22:21 important. One way to emphasize it by repeating, I can just remind

22:28 assume you're I'm sure you've gone into and into a talk and somebody is

22:37 about some llama or something aram and are struggling to remember what it

22:43 And they go on and on because have essentially assumed that, you

22:48 and remember that your um and it be something that is in, you

22:53 , in an undergraduate computer science course , but that doesn't mean that you

22:58 everything. So instead of assuming uh people know, you remind them to

23:05 , you know, as the pythagoras says that the square of the some

23:11 the sides is equal to the square the hyper luminous. And then go

23:16 there were also saying, I assume knows what by the garden door my

23:20 pythagoras is and not said, so helps. Examples are really important.

23:31 less technicalities, more examples are really critical in making a good

23:38 So let's move on. Use logical . So you're just talk in a

23:46 , it's like a story, send order in which you uh you tell

23:52 is important and you have to pick order that makes the best sense to

24:00 uh an audience that's not familiar with subject and it takes some thinking because

24:05 are not someone who doesn't know much the subject, The audiences.

24:09 you have to think in terms of audience, how do I should I

24:13 an example in the beginning? Should put examples in the middle, shouldn't

24:17 put some key results in the beginning that is really important to have the

24:23 follow and stay engaged as much as , avoid forward references. So you

24:31 say, well, I'm gonna use results, I'm gonna prove it later

24:34 the later in this talk. And it is unavoidable. Uh, you

24:41 , it depends on BB, depends is so you have to do one

24:45 the other, but the most times is avoidable. If you organize the

24:51 right, that it step by you build a story instead of

24:55 you know, this story depends on story that I'm gonna tell you

24:58 Um, and such, so Usually a whole bunch of steps, so

25:06 want to motivate each step and tie back to the story, right?

25:11 you have some central goal here. every now and then whatever you're talking

25:17 , you say this is why this important. You may or may not

25:20 followed. I'm on step six and made my goals clear in the earlier

25:26 , you may or may not have remembering or clearly followed steps 1 to

25:31 , but this is why Stop six important and how it helps. Uh

25:37 main story or the main result that trying to, trying to get out

25:44 this, the main idea that I'm to build with this story.

25:51 one little detail here, the order which you're dead. The research is

25:56 relevant to the order in which you your talk. So a lot of

26:02 students would say you know I did that didn't work hard, I did

26:06 that works somewhat but there were issues I did this, nobody cares the

26:12 in which you did things and there have half hour. I want to

26:17 the best that you learned and the that you have if really if a

26:22 and C. You did something didn't out, didn't work hard. But

26:27 you have the that is a beautiful for the all the problems in the

26:32 . I'm just interested indeed. So yeah the order, forget the

26:39 Just just see the order that's important the order that makes sense to the

26:44 not the order in which you did work time time is precious. You

26:51 to size talk to time would leave time for audience interaction generally planned to

26:59 be done sooner rather than later, if it's a tightly time taught like

27:04 conference truck. And you also sometimes very hard to figure out how long

27:12 will take for those situations. Have plan, you can say that you

27:17 I'm gonna do A. B. . And has part one, part

27:22 , B. Has 12345. And has uh you know 12 and three

27:30 you want to check somewhere in the and in the middle and said look

27:35 things are really going slowly, I a plan where I skipped three and

27:40 and to hear and then get to end. So if you have this

27:44 as you are planning your talk, it will be much easier to implement

27:50 when you're doing, when you're actually the dark and most important, you

27:56 include everything. Okay. The idea a talk is that not start with

28:01 and then shrink it and shrink and it and until it fits the

28:05 you basically decide what's important enough to included in the talk and what's

28:12 And then you build from there, things are important, must be included

28:16 cover them in the talk and definitely doesn't have to be in the

28:21 That's the function of the papers to all the details, timing is

28:28 There are some little things uh you to be looking at the audience when

28:34 giving a talk. Uh some people , you know, looking at the

28:38 , some people are looking at their constantly on their feet. That's not

28:42 good idea, not just because it bad, it's also how you tell

28:49 the audience reaction. So once you at the audience, you have a

28:53 idea of where the audience stands and helps you helps you keep your talk

29:02 the right lower. And one thing see is people sometimes are constantly reading

29:09 computer science start, you don't want be reading out of a paper or

29:13 . Yes, you want to look your slides once in a while,

29:17 mostly you want to be talking to audience. So you also, this

29:28 was about the the ice part, is about the speaking and the ears

29:34 , you want to speak slowly. , some people, especially from other

29:39 have a habit of speaking very fast speaking slowly is always easier to follow

29:46 that's one of the issues you have clearly, it can be learned to

29:52 clearly and project your voice so you want to be shouting and you don't

29:57 to be whispering and uh the right may or may not be obvious to

30:02 , but you can ask your friend said there's a certain level at which

30:05 can reach the audience and uh but uh comes across is really loud and

30:14 little trick is positive. So once give a bunch of information or you're

30:26 from one sub topic to another or asked audience a question after that you

30:39 . Okay, so that's one thing learned while teaching is that when I

30:45 students sleeping in the front row, thing that would cause them to wake

30:51 wasn't me shouting and screaming or It was when I stopped talking for

30:59 more than 10 seconds that is like just suddenly wake up and say,

31:03 know, I don't know what's the, you know, the background

31:06 is gone. So anyway, so was deposit strategically as, um,

31:11 for organizing your talk more little things somewhere in the middle to this side

31:21 the size of font. That's But it's amazing how often you still

31:29 visuals that have tax sizes on this make them big enough so people can

31:35 . Um, sometimes it takes extra because you have a graph or something

31:39 the size is determined automatically. But your talk. You need to find

31:43 way to make things readable, try read this paragraph and think to yourself

31:50 wrong with it? So, so there's a reason that most starts have

32:07 and slides tend to be bullets. cannot have full paragraphs, full

32:12 full details on your view graphs. you need to organize and only have

32:18 key points there in a structure that's like these are the points on which

32:24 , you're talk is hanging. Those not the details of it. And

32:28 you put too many details, it's difficult and boring for the,

32:35 uh, for the audience to follow you're trying to put on yourself.

32:42 here's a visual with so many colors and so on. And the point

32:47 trying to make here is that it's to have visuals that are clear,

32:55 and distinguished and it's good to um, sometimes illustrations and animations and

33:03 on. But it's uh, you overdo it. You want to keep

33:10 simple but still be able to speak the audience. You don't need this

33:15 points and effects and so on. just sort of distracting. Richard,

33:21 want pictures, pictures are good, want visuals you want not just grass

33:26 , illustrations and whatnot. So for of reasons. One good picture can

33:37 start with the medal 1st. 1st all, good pictures are really worth

33:42 time you spend on them. That you have some good visuals. Really

33:48 help you explain the point that you're to make and it's hard to make

33:52 good picture and sometimes what you have and then you can use it over

33:56 over again to make your basic So pictures really help explain things.

34:02 a side issue here is that with good picture or even a good graph

34:07 a diagram and you can say many of explanation if you're short on time

34:13 one visual, it gets to the of it. So it's worth investing

34:17 diamond pictures. But this is not that you put a whole bunch of

34:22 from the bed and pack your um with it occasionally. Some funny visuals

34:28 good, but you want to make own visuals about your own talk uh

34:34 have the impact. Alright, this is do not get anxious. Of

34:41 you're getting anxious. Most stupid Someone can tell you is do not

34:45 anxious. That doesn't help you at . It makes you more anxious.

34:49 ? So, but how do you so it doesn't help somebody telling you

34:55 the talk. Do not to get . But there are things you can

35:00 to avoid getting anxious, okay. and those things have to be done

35:05 the days before. They are not the time, first and foremost,

35:12 practice, get experience. It's amazing much different that makes in terms of

35:17 building the confident confidence, not being and shears and being able to give

35:23 talk. Then some little details before talk, the first, you know

35:29 15 minutes or half hour or an . You want to sit quietly and

35:36 your thoughts. If you're at a , that's not the time. You

35:40 to be hobnobbing with everybody. You to keep the focus on your talk

35:45 another micro detail is that once especially if it's a conference or

35:52 you want to go and try your equipment and your laptop and see everything

35:59 . Um it's not that things are going to work. You go there

36:04 let's say you see that the projection coming on, then somebody can and

36:09 , you know what, you need change the settings of your monitor and

36:13 and of course after a few minutes works beautifully, but you lost your

36:18 of thought. It happens so often suddenly you have to do a context

36:23 back to your heart and then in first few minutes you're going too fast

36:28 you just uh, you forget things so on. So it's good to

36:34 , you know, I'm not going have to worry about anything before they

36:37 the actual dark. Um, everything be taken care of if you plan

36:43 and finally, if you really do um, um, you know,

36:52 really, when panic strikes, you sort of feel uncomfortable, you think

36:57 things are not going well or you something or you've been speaking too

37:03 Well, this is again, easy . Take a deep breath. Take

37:07 seconds. We organize your parts and get back to the top.

37:12 don't be afraid to do that. better to do that than for

37:17 somebody, you know, talking 100 a minute and just sort of like

37:21 on and on and then finishing the actually in 10 minutes instead of 30

37:26 nobody has followed anything. All Those are were the things that we

37:34 , uh, said we shouldn't Now we'll translate many of those two

37:41 that we should not do. And going to be the final section for

37:45 presentation. So seven deadly sins is mistakes we all make since 1st and

37:55 are trying to include too much going your time. So what happens time

38:02 almost up and you're halfway through your and uh, you midway through,

38:09 just going through the slides one after other, you know, just not

38:13 time to actually do any justice to . And finally the wash care says

38:19 talk is over, but the talk is over and you didn't spend enough

38:23 on the important stuff. So we're to this point for the second time

38:29 you plan and organize well and then should not happen. This is one

38:34 the biggest mistakes we see in people talks, plan what you can cover

38:41 a talk and only include that Not everything. And then we'll see

38:45 the fly what there is time for what there is not being boring is

38:52 good. A talk is a public . Your papers might be boring,

38:58 in attack you can, you have try to make things interesting.

39:04 so you want to be energetic, , enthusiastic. So uh, you

39:10 , you don't want to be, know, really jumping up and down

39:13 table, but you also don't want be standing in a corner and just

39:17 as if, you know, some lost the back and as a

39:20 you have to, you know, this chapter or something. So the

39:24 is, if you don't seem interested you are interested, but sometimes you

39:29 know, you just sort of speak a monitoring and nobody can tell if

39:33 interested or not and the audience would care. So you don't need to

39:40 an impression on the audience independent of technical content of what you're saying.

39:47 in the end, if you really think that your content is uh

39:53 interesting, your research is not then do something else because has gone

39:58 and you're not being paid big bucks do what you're doing. Speaking a

40:07 mistake, especially with international students and speak uh, not very clearly.

40:16 don't mumble, you can learn not mumble with practice. Don't talk in

40:23 monitor. You need to increase your . You need to slow down.

40:27 need to pass, this is This is not important. And then

40:32 talk about this uh monitor and puts to sleep. So you want to

40:38 it as much as possible. Don't jargon or undefined terms um that there's

40:44 more annoying than someone going on and with some buzzwords that as an audience

40:52 , you don't know little things don't your woods or endings. Um,

40:59 these things are little details, but can ask someone uh what you do

41:06 quite right and you can practice the that as much as possible. So

41:13 mannerisms that distract your audience from what saying and you don't notice that,

41:21 some of us have like they have pen or a pointer or something in

41:26 hand and they're just waving it all time. Yeah, they're they're waving

41:37 uh in the air very rapidly. there were laser pointer around, it

41:42 like they're shooting everybody in the They don't even think or realize

41:46 And uh so yeah, so you to avoid things that you may not

41:54 , but everybody else just notices everybody has different ways of doing

41:59 Some people look at the ceiling, people wear things and so on.

42:03 want to learn what they are for and stop doing that. And a

42:09 of us have accidents, uh english not have been your first language and

42:15 amazing if you just learn to speak people find it easier to follow you

42:24 topics, arrogance that uh which mostly out when there's a question, once

42:33 , you may hear a question which you is just like the, it

42:39 like the, you know, the member asking the question. Um you

42:46 , I didn't follow any of you know, first anything on the

42:50 and now they're asking questions is completely because all the questions they're asking,

42:56 answer them clearly in the talk. , so that may or may not

43:01 the case, but one more time need to be polite and uh um

43:08 yeah, polite and respectful when you're questions and chances are that you may

43:14 it's a stupid question, but it or may not be, the audience

43:19 not know what you are saying. , may not have followed your

43:26 or may or may not have followed talk, but there might be a

43:30 more knowledgeable about other things that you not know anything about. So,

43:35 all events, when a question is , you want to be polite and

43:40 and that's that's that should tell well, no, what if you

43:47 your audience? What if your midway your car and, uh, you

43:52 , sometimes you get the feeling this not going well, so, and

43:56 does happen even teaching a lecture. it happens giving talks, it happens

44:02 you're in talk, it happens all time that you're not, you

44:06 you lost track on the top. you have to see if you're losing

44:12 audience audience doesn't seem interested, then might be the reason? Okay,

44:19 it's over their hands. You you're just assuming things that the audience

44:25 know then on the fly, you slow down and maybe back up and

44:30 explain some things, especially if you get some feedback from the audience,

44:36 it's beneath their interest. Sometimes you have underestimated the audience and it seems

44:43 the audience knows all this stuff that going into the early parts of the

44:48 , then you want to speed up get to what is new about what

44:51 saying. And sometimes you find What do you see him flying for

44:56 first 5 to 10 minutes and then they don't seem to be following,

45:02 are that you made a big You forgot some in between steps and

45:07 they can't so they can't connect, beginning to the end and one more

45:13 , if you can detect that you try to bridge the beginning of the

45:17 to what you're saying to fill it . And um one way to keep

45:24 interested is to have relevant examples. the mayor may not follow all the

45:29 of what you're saying, but examples help and how you find all of

45:36 is one more time I contact looking the audience, you can tell uh

45:41 least up to a point what's going . So one of the mistakes for

45:50 there is no excuse is having material your presentation that you don't understand.

45:58 sometimes you say, you know, read in the paper, this has

46:02 explained in such and such paper and just put it in your in your

46:06 point saying, oh, it's been , explained that paper. So that's

46:11 reference. But you didn't actually read paper. You can't just because somebody

46:15 you uh that this is how it done or you heard or you read

46:21 can't just put it there unless you understand and can completely explain your talk

46:30 yours, anybody can challenge you to any part of your talk, even

46:36 you're talking about somebody else's work. you want to make sure that you

46:42 completely explain and defend every aspect of thoughts. So that's the end of

46:48 presentation. What I want to end the most important is that everybody can

46:54 to give good talks and I've seen many, many times in my

46:59 especially the first year or second year students have large, find it very

47:06 two, uh, to give but after lots of talks, good

47:11 bad, lots of practice their in final year and they're actually pretty good

47:17 , you always need to plan and your talk. You know, some

47:21 are just sort of bone speakers and can just show up and start talking

47:26 time. But for most of us need some planning and organizing to be

47:29 to give a decent talk. Think the audience is point of view about

47:35 the things that we've talked about in lecture. Oh, so naturally,

47:43 you put yourself in the shoes of audience and say, hey, how

47:48 this be done? So that's a good way of thinking anytime your question

47:53 your organization or your delivery, think the audience will think and if you

47:59 uh, imagine that find someone well was willing to suffer listening to you

48:06 say, hey, how does this with this? Okay, keep the

48:11 on key points and ideas. For of the research project, there is

48:16 central theme and the central gulf. uh however, most of the time

48:24 spend in the actual research is some things. Getting the details right,

48:29 the experiments right and so on. sometimes when you try to talk,

48:34 want to talk about those things, experiments, all the things that went

48:38 and all the difficulties you had because took 90% of your time. But

48:44 is usually not the right way to it. You have to focus on

48:49 reasons you're doing the research and the important results that came out of it

48:54 the most important ideas in your Not all the details that go into

48:59 . And to end here you practice what is the reason why everybody can

49:06 to give good talks. If you get feedback, you will get

49:11 And if not an amazing speaker, can become a pretty good speaker.

49:16 can become a pretty good speaker. am going to end with that.
