I just want to build with you black girl. Tell me how you really feel I just want to keep it real with you. I want to live better eat better. I want to love better sleep better I want to feel so alive It's a blind one time for the state of mind two times for elevated Why do women gravitate towards Projects and they complain about the project being a project instead of The guy saved his dominoes in your phone.  Yeah, I mean, I think that a lot of women out here Including myself at one point are very broken and Good relationships as far as being able to accept a Person that's just good to you and you know, they're good for you And they might not be able to check all the boxes, but you're like, okay I see this person and they're really good for me. Let's go ahead and settle it down That comes from like a deep sense of just like a healed individual So like if you're just like broken, I feel like you're always groveling for something You know so women want that man that's like They don't exactly treat me the way that I want to be treated like we know Then they get on treat you right But if you're not healed enough to understand How someone is supposed to treat you then none of it really matters And we weren't really Okay, I can't say we gonna say The people that I come to have come in contact with We weren't like given step-by-step instructions one like this is exactly how things should go it was just kind of like Going with the flow type of thing and when you do that and you have so many like external influences like Friends in high school college education system all of the things it's easy to get Side rail does easy to be influenced So if we're not healed our parents aren't healed and our grandparents aren't healed and it's just like a whole cycle of things So yeah, that's my answer to that question So They've done like surveys were like let's say a male influencer or I'm actually about to combine two questions a male influencer or Stylus for instance, we'll put on a suit and that type of swag and You know go out and carry out a survey with women like and Then he would go out again in street style and carry the survey and survey was like which style do you prefer? The overwhelming majority of women voted street style over the suits and when I say shoot like these are Taylor James Bond looking niggas So The first question is why is that? The second half of that question that kind of ties into the first half is you know Roger Conner is He's a male model He has the the wife or the girlfriend that's chocolate kind of yeah Yeah, good looking dude handsome dude, right? Absolutely. They did a They did a social experiment with him as well where they put him In a bar setting this was staged obviously and they recorded him with two different demeanors And then they showed the recordings to a group of women the first demeanor was more of a so in both clips He was sitting at the bar trying to get the attention of some woman The other side of the room, right? And the first one he was more like stoic more somber almost like you know You know what I'm saying? What was he wearing? Same thing both. Yeah, the closer the closer in consequential. This is just a look, right? Okay, and then in the second one He was more so like happy and goofy like he's smiling. Hey, you know and the overwhelming majority of women voted for them You know I'm saying Serious stoic somber bad enigma guy, right? So the first question is why Are we more attracted to the street style versus the soup style and why are we more attracted to the more stoic serious guy bad boy versus the smiley happy guy Because it's kind of opposite, right? Okay, so I Would say This is just my theory Sometimes not for me But some women and I will say the majority of women aren't used to men that dress in a certain type of way as far as suited and booted Pocket thing like You know all of the things That someone will they'll like that'll turn them on but some women are intimidated by that So they see the guy that's you know in the Nike joggers or whatever and they're like, okay, I Can bag this nigga or that I can talk to this nigga easy But a nigga that might be suited and booted might be I know just a little bit more intimidating They might come off in conversation As far as like I couldn't keep up with this person a Lot of people no matter the race don't really dress like that They don't like on an everyday basis unless maybe you're like in Wall Street or something They don't dress, you know suited and booted most people kind of chill especially because of the pandemic like you You're really probably not gonna run into somebody. That's like all dressed up, you know however attraction more than likely that woman is attracted to the guy that's like suited Because when I think of going to your question when I think of a guy that suited I do think come, you know, obviously depending on the person I do think of somebody that will be a lot more stoic and a lot more aware of His demeanors and like the way he carries himself Then maybe somebody that's just more lax and I know this is just a you know, there could be someone stoic that's wearing joggers, but mystery and stoicism in silence Is very intriguing to women We'll take it back to primal times like I love to do.  That's more about business so not to say This is kind of probably very much off track We don't know people the goofy nigga could be the stoic one behind closed doors.  No, okay Because of biology Naturally because of biology But like societally Because of biology if you think about it too You only have but so many years so it's like Biology says that you need to Get her done The society also like use that and was like, okay Let's hurry up and get it done. I guess you could say so that's a pretty simple one Because of biology Yeah, okay I mean to elaborate on that just so we can make it a little bit more like Personal not so much logical black. No black because that's what this is about black people.  There's a lot of men that are out there that women don't choose And the woman might you know be you trying to rush it But they're trying to rush it with the person that they want quote unquote So it's like I Don't know We know that we Biology says That we want to have a kids. So that's the number one thing marriage is just the protection that comes with you know Making sure that if I were to have these children, it's just not Me out here in the world Because in the past you're like, okay, my grandparents weren't out here in the world My grandmother wasn't out here in the world just by herself So I think that we don't choose very well, right and we Have options to settle down Every woman has an option to settle down like tomorrow for sure every woman can settle down Yeah Everyone I don't care what you look like Everyone has a nigger that they Okay, everyone has a nigger that they know If you come to them, you're like, all right, let's get it. They'd be like bet Let's do it. But the those usually aren't the ones that the women like So that's my answer to that question


Fiery horse with a speed of light, a cloud of dust, and a hearty hyo silver, the lone ranger. With his faithful Indian companion, Toto, the daring and resourceful mask rider of the planes led the fight for law and order in the early western United States. Nowhere in the pages of history can one find a greater champion of justice. Return with us now to those thrilling days of yesteryear. From out of the past come the thundering hoofbeats of the great horse Silver. The lone ranger rides again.  When Toto riding to Indian territory where danger threatened the new settlers there were passing through the turbulent mining town of Goldville. The lone ranger without his mask and dressed in cowboy attire stopped with Toto. They dismounted and stood at the rear of an angry mob that milled around the sheriff's office. The lone ranger was gravely concerned as he watched a few hard-looking men who moved through the crowd, intended seen on spurring the others to violence. Sheriff Tom Daggett and his two deputies, Pete Bronson and Jim Wells, stepped from the office onto the porch and faced the muttering crowd. Daggett's hands hung loosely near his two gun holsters and as icy calmness as he eyed the mob stopped its forward movement as if he had placed a barrier in front of himself. He remained silent for a long moment as the shouting increased and then as suddenly waned. All of you, I want you to listen to me. I said I want you to listen to me and you're gonna... Many of you want to talk, come up here where I can see and hear you.  The prisoner here, Phil Bangs. He's being held for murder and I mean held. No mob is gonna take any prisoner out of the jailhouse while I'm... The mob gradually melted before the fierceness of Sheriff Daggett's gaze. The two or three men who had been trying to arouse the crowd looked angry. The Lone Ranger watched them for a while and then saw them enter a cafe called Floyd Hatton's Golden Nugget. The Lone Ranger turned to Toto. Toto, those men bear watching. I think we'll stay here a while. Oh, we...not go to Indian territory? Not until we learn more about Phil Bangs and the circumstances surrounding his arrest. I've heard of the man in the past. His reputation was good.  Me think same thing. So while I'm dressed like this, I'll move around town for a while and try to find out what this is all about. In less than an hour, the Lone Ranger and Toto were alone together once more, having meanwhile learned what was to be known about Phil Bangs' arrest. They say that he and his partner Kenny found a new mine in some far-off place up in the hills. Kenny come to town, drink, heap much, say mine, very rich. Yes, I heard that too. He was in the Golden Nugget Cafe drinking hard while he waited for the stagecoach to Central City. After a while, they say he was in a befuddled condition. He bragged about the mine, was telling everyone about the map he carried, the one he was going to use to file his claim, I imagine. But him not file claim? No, he never got to Central City where he'd have to go to do it. He disappeared without taking the stagecoach. When they found him yesterday, he was dead with Phil Bangs' empty revolver near his body. But why Bangs killed him? I don't know, nor does the sheriff. Bangs denies he did. There are too many say they saw Bangs shoot his partner. So on their say so that he's being held. That and the fact they found his revolver nearby. Ah, why they make map? Tear it up, tear it in half. Bangs says they feared foul play that miners had been killed lately before they could file claims. They were afraid it might happen to them. So they drew a map of their mine and each was going to give his half to someone near to him. In the event they were prevented from filing their claim. Bangs' file claim when partner died? No, Sheriff Daggett arrested him before he had a chance. Bangs is suspicious. Says the sheriff is conspiring against him and refuses to tell where the mine is located. Look, cross street. Tuttle directed the Lone Ranger's attention to the two men emerging from the gold nugget cafe. The men who had led the mob a short time before. Oh, those men must have a reason for trying to get Phil Bangs lynched. I'm going back to camp and change these clothes. You stay here and keep an eye on those fellas. See where they go and what they do. I'll be waiting at camp. Sheriff Daggett was concerned about the attempted lynching. Later that day he spoke to his deputies, Pete Bronson and Jim Wells. Good boys. It seems to me that Rog Perry and Frisco Comita were the leaders of that mob this afternoon.  They're the witnesses against Bangs and I don't like their attitude. That's why you two are going to take Bangs over to Central City and lodge him in the jail there. And do it quietly. Nobody will know we're taking Bangs away. All right, Sheriff. But someone did know Rog Perry who had been in the Golden Nugget Cafe earlier had sneaked around to the rear of the Sheriff's building. The building was poorly constructed and the walls were made of thin boards loosely joined. As Perry listened outside a window he heard all that had been said. What he did not know as he hurried back to the Golden Nugget Cafe was that Toto had been watching his every movement. Floyd Hatton, owner of the Golden Nugget was in his office talking to Frisco Comita when Rog Perry entered hurriedly. Hey, boss, Daggett has his deputies, Bronson and Wells taking Bangs over the Who's Gow in Central City tonight. What? I heard him give them orders, boss. He says Bangs will be safe from the mob there. He said that, huh? Yeah. All right, we'll take Bangs before he gets to Central City. I'll go by horseback. Yeah, by the main road after the first mile or so. Boss, we make on Bush. Yeah, Frisco. Rog, you and Frisco get on the hill trail that overlooks the main road at Elbow Bend. Well, that's a good spot for an ambush, boss, but the house where Mrs. Bangs is staying is less than a mile from there. Who cares? You two take Fuzzy Willard with you and ride to Elbow Bend now. But they're not taking Bangs away till nightfall. You'll go now. That's an order. See you leave town later. The sheriff won't be suspicious then.  Kill the deputies, but keep him alive. You still want that, boss? Certainly. The mob had taken him this afternoon as we planned. We'd have rescued him, hit him away, and then go on to work on him till he told us where the mine was or until we got the other half of the map.  If he had told us where the mine was, we would not have to do all this. But he didn't tell us. When I spiked his drink and got him out of the cafe, he wasn't able to talk. Later, when we questioned him, he wouldn't talk. And when he tried to escape, we had to shoot him. You think Bangs' wife, she, maybe, have other half of math? Either that or she has an idea where it may be. Bangs doesn't talk to us, and we'll go to her. We'll prove that we have Bangs hidden. We'll promise to keep him alive only if she tells us where his half of the map is. Good. We get fuzzy then, set out for Elbow Bend. Come on, Frisco. A short time later, the three henchmen of Floyd Hatton rode out of Goldville by one route, then doubled back around the town and galloped along the main trail until they came to Elbow Bend. There they got at their horses up to a trail overlooking the main road and dismounted them. Whoa, whoa. See, boy? The Indian who, unknown to them, had followed at a distance, watched from the thicket for a while. Then he walked his horse away from the scene and, once out of earshot, urged it into a gallop. Get him out of the scout. Tonto, back at camp, told the lone ranger and now three men waded trail over Elbow Bend. You have no idea what they may be up to? No, Kimizumi. Me not hear what them say in cafe.  Ah. Perhaps it has nothing to do with what happened this afternoon, but I'm still suspicious of those men. Ah. The way them ride back a town, not look good. No, Tonto. So let's find out what they're up to. Easy, sir. Easy, sir. Easy, sir. Right up into the hills above Elbow Bend to a spot higher in the trail where you say they're waiting. We go now, Kimizumi. Yes. Come on, sir. Deputies Bronson and Wells led Phil Bangs from the rear door of the Goldville Jail with no one seeing them. Less than an hour later, they were on the main road to Central City, nearing the wide turn known as Elbow Bend. On the trail a short distance above the road at the bend, Rodge Perry peered through the thicket down onto the moon-bathed path below. Suddenly he turned and ran back to where Friskal Kometa and Fuzzy Willard waited by their horses. All right, boys. I see them. Just the three. They'll be at the bend in a minute or so. So get ready. Phil Bangs had remained silent from the time he had left the jailhouse, riding between deputies Bronson and Wells. The two lawmen kept their eyes straight ahead on the road. Less alert now than when they started on their journey. Bangs was the first one to hear and see the three men ride down from the trail above. Look, riding down here. As Jim Wells fell to the road, the three crooks concentrated their fire on Deputy Pete Bronson. Bronson firing back, caught Rodge Perry with his first shot and the man slumped from his saddle. But another bullet finished the deputy at the moment that Phil Bangs' horse fell to the ground. The elderly prisoner, seeking shelter behind the fallen animal, used his manacled wrists as a vice and grasped the gun from Bronson's lifeless hand.  Frisco Camita obeying orders had not fired at the prisoner. But now too late he saw his mistake. As he rode in on the man, Bangs using the index fingers of both hands fired. Now here's one for you. As Frisco fell, Bangs rose from behind the horse, but Fuzzy Willard fired at that instant. The elderly man hit, fell backward. And at the same moment, Willard saw the Lone Ranger and Tuttle riding down the embankment from the trail above. He spurred his horse and was off like the wind towards town. One of the Lone Ranger's bullets nicked the man's shoulder before he disappeared around the bend and the masked man rode onto the scene. Tuttle was immediately behind him. He's hit, Tuttle. He's headed toward town. We'll attend to him later. Right now we have five men here, dead and wounded. Let's see who they are and how they are. The curtain falls on the first act of our Lone Ranger adventure. Before the next exciting scenes, please permit us to pause for just a few moments. Now to continue. The Lone Ranger and Tuttle rendered expert first aid. Only the prisoner, Phil Bangs, was conscious, though he too was wounded and in great pain. Bangs, you'll have to go back to jail. These men tried to free you. No, no, they want to kill me. Them same men who lead mob today. That's true. That's why we follow them here. But why should they... Tuttle, of course. You said this dead man was the one who stood outside the sheriff's office today listening at the door. Ah, him same thunder. He must have heard them say they were going to take Bangs along this road. They were taking me to Central City for safety. I see. Yes, that explains this ambush. But why? I know why. You know why they want to kill you? These men, I mean? Yes. They're with Floyd Hatten today. Is he anything to do with it? I'm not sure. Maybe. Please take me home. Not far from here. Just have a mile. I'll see my wife before I die. You won't die, Bangs. I'll stop the flow of blood. You'll be all right. I still a moment. Tuttle. Taking these wounded men to town on horseback might prove fatal to them. Suppose we put them in Bangs across the saddles of our horses and another. We'll walk them to Bangs' house and you can ride into town for a doctor and a sheriff. The masked man and the Indian leading three horses arrived at the isolated home of Phil Bangs a little later. Oh, there. He's so kind. I'll go inside and prepare Mrs. Bangs for this. Then we'll carry the men inside. Mrs. Bangs was hysterical at first but recovered her composure after a short while. She seemed frightened by the masked man when he entered. But after he and Tuttle bandaged and attended her husband and the two unconscious men, she realized she had no reason to fear them. Standing by her husband, she spoke for the lone ranger. Mr. Phil didn't kill Jeb Kenny. I believe that. You do, stranger? Yes. I'm going to help you if it's possible. I arrived here only this afternoon and I heard part of the story about you being arrested for Kenny's murder. I'd like to hear your side. Phil, I'll tell the man. You keep quiet unless I tell it wrong, all right? All right, Katie. Katie Bangs told how her husband and his partner had found a rich vein of gold in a spot where a few men had ever traveled. They made a map of the location and returned to Bangs' home. There, they decided to tear the map, each retaining a half. Jeb started drinking, sort of celebrating his good luck. He never got the stagecoach to Central City. He was due back yesterday morning. He never came. He'd been killed the night before. So they say, Phil started to worry when Jeb didn't show up. So he gave me his half of the map to hide while he went to town to look for Jeb. I told him not to go, but he did. I never got there. Sheriff Daggett and his men arrested him on the road. They were on their way here when they met Phil, riding in. Daggett, give me a chance to talk to him. They found Jeb's body that morning with Phil's pistol just a few feet from it. I loaned my pistol to Jeb before he went to town. He didn't have one. I told his sheriff that. He didn't believe you. No. Those two fellas, Perry and Kamita, they said they saw Phil kill Jeb, swore it on a Bible, and said he did it in cold blood. I was here all the time night before last. The sheriff didn't believe that either? No. He told me he was going on the evidence he had on hand and the witnesses said if we had a story, we could tell it at the trial and could produce our proof then. I said I killed Jeb because I wanted the mine all to myself and asked me where it was located. You didn't tell him? I'm not telling anybody. Not till I walk into the claim office in Central City and file it. I see. What about Kenny's half of the map? He may have mailed it to his daughter. I don't know. All I know is it wasn't on him when they found him. The sheriff says so. So that's the picture. Mrs. Bang's right now. I'm going to town for the doctor. Potter will remain here and look after all of you. While I'm in town, I'm going to do some investigating on my own. The lone ranger in Goldville a short time later wrote a note to the doctor. Then he placed it under the doctor's door, knocked loudly on the panel and retired into the shadows. Seconds later the doctor opened the door, looked around, then picked up the note. Within a matter of minutes, the doctor galloped off on the main trail. Get out there. Come on. The lone ranger turned and walked to Sheriff Daggett's office going to the rear door. Sheriff Daggett was preparing to leave his office for the night. When he heard the rear door of his office closed softly, he turned quickly to face a masked man who held a gun pointed at him. What's the idea? Who are you? A man who admired your courage and integrity, Sheriff. A friend. A friend? Where in a mask can a holding a gun like that? That gun was merely a precaution, Sheriff. I'll put it away and hold a silver bullet instead. There.  What does it mean? If I tell you I have a white horse, a great white horse named Silver, and that my best friend is an Indian named Toto, I... You won't have to tell me any more, stranger. Now that I see you, I recognize who you are.  I know it. What brings you here? Your deputy Pete Bronson has been killed, Sheriff. What? And Jim Weld is badly wounded. Bronson dead? Oh, no. Yes. And there are other dead and other wounded, too. Listen. The lone ranger told the story of the events at Elbow Bend and what he and Toto had done. Sheriff is strange that the witnesses against Bang should be the men who killed your deputy and tried to kill another one and perhaps Bang's, too. Yes, I realize that. What did you learn about Jeb Kenny's last hours around here? Nothing. I've tried to learn, but no one saw him. Last time anyone saw him was last week when he was in Floyd Hatton's café celebrating. Drinking up all the red eye in the place. Hattons? Yes, that settles it. That's where the answer to everything lies. Yeah, what do you mean? Once more, the lone ranger explained. This time, about Toto's following Raj Perry to Hatton's office. And how Perry and two other men rode to Elbow Bend after that. Then the masked man followed with a brief outline of the story told him by Phil and Katie Bangs. The sheriff's eyes narrowed. Well, I'll be... I never thought of Hatton, though I should have. He owns more mining property and all the prospectors in this section. How did he get it? Well, he said it was a repayment for grub steaks. Oh. But stranger, I see what you have in mind. Then the lone ranger outlined a plan. When he finished, Sheriff Daggett smiled. Go ahead, stranger. When you ride out of town, don't bother to look over your shoulder to see if you're followed. I'll have my men close to anyone who decides to treade you. Thanks and good luck. Floyd Hatton had closed the door to his office when the wounded fuzzy Willard had come to his office a short time before. Willard explained his delay in reporting the incidents at Elbow Bend. You know it's bleeding bad. So I went to the doctor and had him fix up my shoulder. It's not so bad now. Who cares? So that coyote bangs killed Frisco, did he? Yeah. Pulled up and shot him before I got him first. Who were the two who rode down on you? Well, I don't know. One of them, the fella in front, seemed to be wearing a mask. He was. Stop right there, Hatton. You're covered. How did you get in? That rear door. I heard a few things you were saying. Hatton bangs isn't dead. You winged him but didn't kill him. You were one of the two who came after fuzzy here? Yes. Hatton, I'll not waste time. I want Jeb Kenny's half of the map. You want... how did you know that... I don't know what you're talking about. You'd better because I have Phil Bang's half. If Bang's lives, my half won't be any good. Only he knows where the mine is. Yours won't be any good either. It sounds interesting, this stuff about mines, but I don't understand. Then I'll tell you more. We'll get rid of Bang's together. With him out of the picture, we could share that mine. I know the truth about Kenny. You either share your half of the map with me or... You say you have half a map? Yes, but it don't look like that. It's not here. I won't produce it till your half shows. Where is it? I have no half a map. Then I'll tear up mine and turn Bang's over to the law and give him a chance to file his claim on the property. Good night, Hatten. Hey, boss, you shouldn't have let him go if he has another half of the map. Then I'm going to get it. Plus, I never mind that I'm yours. We're going after the mask man. We'll find out where he has that map and Bang's. Hurry before he gets out of town. The lone ranger wanted Hatten to follow him in order to carry out the plan he had in mind. He left town slowly. He was on the main road when he glanced over his shoulder and saw the horseman following him. He smiled to himself and sent the horse into a gallop. The lone ranger hurried into the Bang's house a short time later. But where's the doctor and the other two men? The doctor's got them in the bedroom. Fix them up. The engine's there too. Good. Bang's, where's your half of the map? I want it. Don't ask me why. I needed it once in order to help you. It's here somewhere, isn't it? I'm not telling. Phil, stop it. Stranger, I trust you. Right here in the chimney. I'll get it for you. Here you are. The lone ranger had the torn map in his hand only a few seconds when the outside door flew open. Hatten and Fuzzy Willard guns drawn, stepped inside. Beautiful timing, isn't it? Let me have that map. No, no. Don't give it to him. You can't have it. I'll die rather than let you take it. Stranger, give me that map. Stand back, Mrs. Bangs. Fuzzy, you grab her. I'll take care of this mask for him. Wait, Hatten. I made you a proposition. You supply Kenny's half of the map?  I'm keeping that and taking yours. When Kenny started boasting about having his half, he at least could blame it on a drink. That's when you killed him? Is it matter to you? Now, we kill him later when we got his story about his partner Bangs. It was a nice frame-up you worked on, Phil. It could have been better. When we kill you three now, we'll be sure nothing goes wrong. Be sure you kill us first. You see, everything's gone wrong, Hatten. What are you talking about? Stay, boss. Let room in. I'll take that gun, Hatten. You're not too strong, are you? We have gun against him. Step back, Hatten. Nice shot, Toto. Man with bad arms, start to fire. Let me get him. All right, you two. You got me. What's your game? I'll play it now. Really? How sociable. Hatten, we don't have to ask you where your half of the map is. With Bangs alive, finding the mine will be easy. But I thought you wanted him dead. Like you did when you tried to have him lynched? We weren't going to lynch him. We're going to trade him his freedom for his half of the map. Oh, so that was the idea. We didn't mean to shoot him at Elbow Band either. We're going to rescue him and propose the same trade. How awful. You killed a man to... Oh, who are these men? Sheriff Daggett and his deputies, Mrs. Bangs. They'll take over. Yes, Hatten, you and Willard didn't know we followed you here, did we? What's happening here? You say you followed us? Yes, we followed you all the way. You heard the important things you said just now, too.  About murdering Jeff Kenny, about framing Bangs, about the lynch mob, everything.  You'll hang for this. I'll be able to thank the mask man for what he's done for me. I can see what he's done to me. Why did I have to listen to him and... Hey, he's gone. Who is he? He's the one man people like you should never come in contact with, Hatten. Because he's the one man who will save the West by driving you and your kind out. He's the Lone Ranger.

Hi, I'm Zor. Welcome to Indizor Education. So we are continuing talking about oscillation as a kind of movement. Now, the previous lecture was about oscillation of the pendulum, which is basically just going like this. This lecture is about the spring, which is stretching and then contracting again. Slightly different way of movement, but again, it's kind of an oscillation and there are obviously proper equations which the movement should satisfy and we are going to come up with these equations right now. Now, this lecture is part of the course called Physics for Teens presented on Unizor.com website. I suggest you to watch this lecture from this website. There is a prerequisite for the entire course of physics. It's the course of mathematics on this website. It's called Maths for Teens. And the website contains some other courses like US Law for Teens, for instance, etc. Now, the site is completely free and there are no advertisements, so I do recommend you to watch it from the site because every course has certain logical segments of educational material presented. It's not just you just found one particular topic which you are interested in, somewhere on YouTube where all these lectures are actually stored and just watch this lecture. All the lectures are interrelated. It's the course, basically. Now, the Maths for Teens is a completed course. Physics for Teens is being done as we speak. Right now, we are in the Mechanics and we are talking about springs and spring oscillation. All right, now, back to business. Let's consider, we have the following situation. Here is our spring and this is the spring in its neutral position. Neutral means that it can stretch a little or it can contract a little and this is the neutral level. Then we have a little weight here. Obviously, a point object which has certain mass, M. Now, what happens with the spring if we just hang this object? Well, it will stretch a little bit, right? Under the weight of this object and we are talking about the weight, so there is something like a G, which is a free fall acceleration. So, the weight is M times G. This is the weight, M times G. All right. Now, everything is not moving. It just stretched a little bit and that's it. Now, what happens if I will take this particular object and pull it down a little bit and let it go? Well, obviously it will start oscillating. Up and down, up and down. And if we are talking about ideal spring, which doesn't have internal friction and air resistance we ignore, etc., etc., it will just continue oscillating indefinitely. So, this is kind of an ideal situation and we would like to come up with the law of the motion in this particular case. All right. So, first of all, we are dealing with the spring and we have to know how spring actually reacts when you are stretching or contracting it. Well, there is so-called Hooke's law and the Hooke's law tells that if there is a spring at certain neutral position, then the force, this spring, exhorts, if you are stretching it, is proportional to the distance you are stretching. So, if you have a spring like this and you are stretching it like this, now if this is the neutral state of the spring and this is a stretched one, so the difference between these two, this difference, is the difference I am stretching from the neutral position. And the force which spring in this case, it resists the stretching, it's trying to contract again. So, this force is equal to minus k x, where x is the distance I am stretching. k is some kind of a constant. It's the elasticity of this particular spring. Obviously, different springs have different elasticity. So, in this particular case, I assume that k is given. So, we know what kind of a spring this is and what it's coefficient of elasticity. Now, I have to warn you, however, that this is a very, very approximate law, this Hooke's law. It works more or less precise if these stretching are really small. I mean, if you are stretching the spring significantly more than its original length in a neutral position, then the Hooke's law will not be as precise. So, under certain circumstances, within certain relatively small degree of stretching, this is working. And we are assuming that that's exactly the case right now, because that's the only thing which we know about this spring. If it's a more significant stretching, etc., we don't have any laws to govern derivation of our equations, right? So, we are assuming that this is the case and the Hooke's law is is working. Now, another thing which should be given. So, we have mass, we have acceleration of the free falling, we have the elasticity of the spring, and then I will probably have to say what exactly is the amount of stretching. So, if this is the neutral position and I have stretched, let's say, to this level, so this is initial stretching of this object on the distance L from the neutral position of the spring without any load, right? So, L is also given, that's initial stretching. And then I let it go. Now, obviously, what we have to do right now is position of this particular object at time t would be a function of the time. So, x is the distance from the neutral position to current position of the object. And that's the function which we have to determine, all right? Now, first of all, I told you that we have stretched initially at moment t is equal to 0 to the length L from the neutral position. That means that we have an initial condition this. Then I told you that we just released this particular object without pushing it in any direction, which means that my first derivative, my speed, is equal to 0. Now, we will come up with some differential equation for x of t. These are initial conditions, and we will apply these conditions to some constants, which will be part of the general solution of the differential equation, and we'll see what happens. All right? All right, now. So, let's think about what kind of forces are acting at any moment t on the object of mass m if it's on the distance x of t from the neutral position. Well, there are two forces. One force is the weight, and that's always the same, m times g. And another force is into the opposite direction, f, which is equal to minus k x of t. Why? Because x of t is the stretching of the of the spring. This is position where we are stretching the spring. Minus because it's directed to the opposite direction relative to the weight. So, we are assuming this down is a positive direction of the x-axis, right? That's what x is. And the k is a known coefficient of elasticity of this spring. Now, the combination of these two forces is basically the resultant force, which gives our object certain acceleration, right? So, if w minus f or f minus w, it all depends on their their relative position, that would be well, actually, I should say plus because the minus is already here. That should be the resultant force, and it should be equal to m acceleration, and acceleration is a second derivative of x of t. So, x of t is the distance, the first derivative is speed, and the second derivative is acceleration. All right, so basically this is a differential equation which we have. Now, let's put whatever we know about this. So, w, the weight is mg. Now, the force of the spring, the elasticity is minus k x of t, and it's equal to m x second derivative of t. This is differential equation, and it's a linear differential equation. In the mass for t-ins, I touched these, and I explained how to solve these relatively simple differential equations. So right now, I'll just write down the solution to this particular differential equation, and then we will talk about what exactly are the constants it depends upon. Now, the solution to this is something related to trigonometry. If you remember, the derivative of a sine is a cosine, derivative of a cosine is minus sine, so that's how we are relating to second derivative and the and the original function. Now, this is a little complication, but everything is taken care of. Now, my general solution to this particular differential equation is the following. It's one constant times cosine of t-con times square root of k over m plus another constant sine of t times square root of k over m, and then I need a free member plus mg divided by k. This is the general solution to this equation. All right, now what we can do right now is we can differentiate these ones and twice, compare with this, and it will satisfy this particular equation. So, just out of curiosity, let's do it relatively quickly. The first derivative is minus c1 from the cosine is a sine, and then there is an internal function sine of t square root of k over m. Now, plus c2 again square root of k over m, the derivative from a sine is a cosine, t times square root of k over m. Now, this is the constant, so the first derivative is 0, and my second derivative is minus retains. Now, this square root and this square root will be k over m cosine of t square root of k over m, and this will be also minus c2 no, not a square root anymore, because it's a square root times square root, so it's playing k over sine of t square root of k over m. Now, what happens if let me make this a little bit simpler, I'll divide it by m and see what happens now. So, the second derivative is this one. Now, if I multiply it by k over m, if I multiply this xt by minus k over m, I will have this minus k over m cosine, which is this one, and then minus from the, it will be k over m sine, which will be this one. So, if I will multiply my x of t, this one, by this k over m, this will go to this, this will go to this, and what happens with this guy? If I will multiply it by k over m, I will have only g left, g left. So, this is exactly this multiplied by k over m, by minus k over m plus g, right? Okay, so this is a solution. So, we have the expression, but it's depending on two different, it depends on two different three constants. How can I get these constants by initial conditions? So, this is the initial position. We stretch it by l. So, if I will put 0 into this function, now, this would be 0. This would be 0, so cosine of 0 is 1. So, I will have c1 plus mg over k equals l. So, c1 is equal to l minus mg divided by k. We've got that. Now, now from this, I have to take the first derivative. Now, the first derivative, this will give me sine of something with some coefficient. So, in 0 it will be 0. This will be cosine. So, it will be c2 times square root times cosine of 0, which is 0. This will not be participating in the first derivative, because it's a constant and the first derivative is also 0. So, I will have c2 times something is equal to is equal to 0. So, c2 will be equal to 0. So, here is my final formula. x of t equals l minus mg divided by k cosine of t times square root of k over m plus mg divided by k. So, that's the formula and it gives basically the behavior of the position of the object at time t as a function of time t. So, what can I say about this? First of all, it's the oscillations are trigonometric function. So, which means it's really going up and down, up and down to infinity. That's one thing, one observation. Now, another observation is what happens if l is equal to mg divided by k? If l is equal to mg divided by k, what does it mean actually? Well, it means that lk equals to mg. Now, let's think about what is l times k? l is my initial stretch of the spring relative to the neutral position. Times k gives me the force with which spring tries to pull back. mg is the weight. So, it looks like on my spring I have stretched the spring exactly to the position which is producing the force directed up exactly equal to the force directed down. So, the force of the spring is completely balanced the force of the gravitation, the weight. And obviously, this thing will not move at all. So, if it's already stretched a little bit by this particular length, l, which is equal to mg divided by k from the neutral position, then this is an equilibrium point. So, my object will not move up and down. Only if I will stretch it a little bit from this equilibrium point, then it will start moving up and down. So, otherwise, if l is equal to this expression, this gives you zero and we will have a constant position of my object, it will not move at all. Now, if l is less than mg divided by k, that means that I didn't really stretch it, I really pulled it a little bit up. So, it will start from the upper point and then it will go down, up, down, down, etc. So, that's all kind of simple thing. So, basically, that's it. So, we have derived this equation. Now, I would like you to recall the previous lecture where we were talking about pendulum. Now, in case of pendulum, if you remember, we had a differential equation which cannot be solved in simple algebraic formulas and we had to really consider that the angle which we are tilting this pendulum is really small, in which case the sign of something can be replaced with that something, just because the sign of an angle and angle itself in regions are very close to each other whenever the angle is very small. Sign of the angle and angle are very close if the angle is small. So, we made this particular simplification and then we were able to come up with another equation also depending on trigonometric function, so-called harmonic movement. Harmonic means it basically behaves like sine or cosine. And here also. Now, does it mean that in this particular case we really didn't need any simplification? We did need that simplification in case of the pendulum and in this case we really didn't resort to it. Well, not so fast. The universe is infinitely complicated, let's put it this way. We have simplified already by using the Hooke's law. I was telling you that the force of the spring is proportional to its stretching or contracting, only in case these stretching or contracting are very, very small. So, that's where we have made this simplification. And unfortunately it's also there and the real life obviously is much more complex, etc. And as in many other cases, physicists decided to simplify their lives and instead of a very, I don't know, really very difficult kind of research, they decided, okay, we will make some nice formula which we will just base our calculations upon, etc., etc., but you have to know the margin where you can move within these calculations. So, the formula for Hooke's law or the formula for any of these equations or the pendulum equations, well, they are okay within certain boundaries. As soon as you are out of these boundaries, don't rely on these formulas anymore. So, for instance, the formula for the period of pendulum which I gave in the previous lecture, in this case, we also can say what's the period of this particular spring-related oscillation. Well, simple, it's 2 pi divided by this coefficient, or I will multiply by its reciprocity. So, this is my period of oscillation in this particular case. So, it's mass, the greater the mass is, the slower will be the oscillations. The stronger the spring is, which means this coefficient is greater, then the faster it will oscillate. So, that's what this period actually means. So, the stronger the spring, the faster it oscillates, and the bigger the mass, which we are hooking to this end, the slower it will be. Okay, that's it. I do suggest you to go to unisor.com to this course and read the textual part of this lecture. This and any other lecture has textual parts. And then there are exams for every topic. For instance, for this topic of pendulum, well, this is the pendulum and the spring, actually. Combine them together. There will be exam as well, and I do suggest you to take it just for your own satisfaction, challenge yourself. That's it. Thank you very much and good luck.

Felly mae'n gweithio, yw'n credu dithatan gwahanol digital, Who are we talking about when we talk about firms that will sell across Europe and engage in that commerce and so on. So this is back to Mark Ruskinow and his book. He talks about if we're going to be part of this digital revolution, if we're going to be a digital success story, he'll say first of all we've got to remake ourselves as people, we've got to think dimensions about digital. Second thing then, we've got to think differently about our companies and thirdly, we've then got to think differently about our industry and if you look at Apple and I'm old enough to remember when Apple nearly went the way of lots of IT companies it was perilously close to go out of business Ond ydy oedd yn ymlaen, Apple haf ystod yn cyfnod o gwasanaeth y cwmfyrder a gweithio'r ysgol yn cael ei gael y bydd yn clywed o'r ysgol. I gael, mae'n gofio'n iawn i ei gael bydd y cwaith cyfnod yn ymddangosol. Mae ymddangosol iawn o'r ysgol, ond maen nhw'n gallu unrhyw ymddiadol. ar mwynt, felly ychydig o'r holl y bydd, ac rwy'n meddwl yma, yna'r cyhoedd. Yn mynd i'r cyhoedd, y cyhoedd cyhoedd, yn y rhan, mae'r cyhoedd y cwmbrais wasanaeth o'r cyhoedd sydd y mgweithio, ac mae'n ddweud eich cwmbrais cwmbrais, ac mae'n ddweud eich cwmbrais o'i wneud eich cwmbrais i'r bobl ac o'r llai'r llai'r llai'r llai. a you know Rostino makes the point about when you're talking about the huge success stories in digital, you're talking about airbnb, you're talking about Uber, you're talking about actually companies that don't do the stuff that they're famous for, uber don't own taxis, you know. um airbnb don't own accommodation and yet that's what they're used for so they're completely remapped What some of these things mean to us all. So back to government. Why is government different? Well, I guess the first thing is we don't really have competitors. You know, we're the government. I mean, OK political level. There's obviously different parties and all that part of being a good democracy but I mean at the end of the day government in terms of the civil service and the infrastructure and so on. It's just there. i'r тыch cofnir, oherwydd o ardiadau yn sgoledig i gwybod. A dyna'r cymdeithas sydd o blaes iddi, oherwydd o grwp gyfaint. A'n siŵn i ddim yn cwysydd ar y cyst Caso, rwyf wedi bod yn ystod i'r lleidiaeth ar y stoed yr yn ymwrdd, ac mae'n rwyf wedi cyfryd â'r ei wneud, hefyd angen. A'r ydych chi'n goblwch i'r bank yma, oherwydd o'r cwysig yr bring steadfynol. ac geron iawn the bank that she had gone through for 40 years, it was almost part of her social life because she knew all the staff and she knew all the people that would go in there. Of course they then went on to set in the letter but this is all part of the brain of New Future and you'll have tele-banking and all this sort of stuff and she said, what does this matter to me? A banks can do it probably have to do it and will do it whether their customers like it or not. If you've been with a bank for 40 years they're not going to ask your opinion gyda'r llwyaf o'r mor gweithio, mae'n gwybod bod llwyaf, a'n gwybod dros y bus oherwydd a'r gweithio'n ddiwrn. Mae'r ddiwrnod cael ei ddod. Mae'r ddannig maen nhw wedi'i cael ymgylchedd. Mae hynny'r digwydd o'i bod hynny a'r ddau'r ddau'r ddau'r ddau, mae'n gweithio'n ddau. Mae'n gwybod heb ddechrau, felly mae'n gweithio'n ddau'r ddau. I was speaking earlier at an event and I was using the example of the identifier. When you think of it, you would not stay with the bank or a retail company that kept asking you for your information when you had already provided it. You just wouldn't accept some of these things and yet when government talks about doing it as a good thing, it gets hit with the media by big brother and infringing on people's liberties and all of this. Government has so many stakeholders that every decision it makes, it can't win. It will have people who are furious about some of the things that it's trying to do, even where it tries to do them with the best reasons and the best intent. Unless we're a stonia with loads of legacy, so again, it would be wrong for my minister to announce that he's dismantling the entire tax system because he's been to a Gartner conference and really what you should be doing to be digital is completely rebuild the processes from start to finish. We've spent millions upon millions on what we've got and therefore there's an obligation to the taxpayer to exploit the value of that. While we develop a new model, that's not a conversation that many businesses have or certainly not the same extreme. And people losing their jobs is always the government's problem. So we were talking earlier on about unpost and the fact that government remains one of its biggest customers. In fact many government is largely the lifeblood of unpost at the minute because the likes of the Department of Social Protection, Revenue and All are literally sending out millions of letters every week. The digital part of us would say we've got to stop doing that, it's part of the old world. But look at the implications if we do it and post offices closed and so on. So it's difficult. So it's hard in government to redefine what success is and how we talk about success. So the government action plan, it talks about, as I said, government being a digital leader, government leading the way being somewhat of a trailblazer. And these are the things that are specifically called out in it. So digital by default. And I was saying earlier on about one of the ways that Denmark have moved towards this is they take the view that if you're capable of carrying out transactions digitally with anyone, you're legally obliged to carry them out with government. That's their view and they've got 88% uptake. It'd be interesting if a minister announced we were going to do that here, what the feedback would be like. Is it a good thing? Is it not? Once only principle, the idea is that you tell us once and we'll use many times. And again, I've touched on that, some of the sensitivities around it. But in the eyes of Europe, that's the right way to go. It's a good thing. Inclusiveness and accessibility speaks for itself as there's openness and transparency. Cross-border by default, I've talked about the idea is you can carry out a transaction with your home government, regardless of where you are in Europe, and regardless of the access device you're using. Interoperability across governments, that's going to be a challenge. Trustworthiness and secure. And it was interesting because I was lucky enough to have a conversation with Andrew Sandsit and I was sent to him that in Ireland we see the counterbalance to a government as being the data protection commissioner. And actually we shouldn't. We should see the counterbalance to a government as being openness and transparency. And that's where the Estonians are. The Estonians, Estonia is a fascinating place to go to because if you go into Estonia, what they'll show you is they'll log on and they'll show you your record in government. You can check that it's correct and you can also check who's accessed it and why. And you can do that with your medical record as well. Now, when you talk about interoperability and cross-border by default, if I was in Spain next week and I was ill, I would want that consultant to know everything about my medical records. What I don't want is people looking at it who aren't entitled to. So this is where this transparency is so important. We need to start putting in our citizens' minds that it's all about transparency and trust and not about... The whole argument at the minute is about effectively a core lack of trust of government. Wherever that's come from and whether it's deserved, that's in my view where we're about at the minute and we need to redefine that argument. So in terms of league tables, European Union actually maintain one. This one's called the Desi league table and these are the best EU government countries in Europe, the 28. Ireland's here and Estonia, Denmark and Finland lead the way. Now the good thing when you're in Ireland is the United Kingdom despite all the money they've spent are still way ahead of us. I think league tables like this are a good thing and a bad thing and league tables really test your culture and your metal when you're in government. What I mean by that is to give you a soccer analogy. Apologies to people who don't love or know much about soccer but if you're the chairman of a club like West Bromage Albion, they sort of sit and their manager was making this complaint in the pre-season. He was talking about their board was happy with mediogridic because although they're miles away from the top, they're also comfortably away from the bottom and that's good enough. And in some respects the challenge for Ireland is, is that good enough? Are we happy because we're so far away from the bottom or are we annoyed or challenged because we're still quite a bit of distance from the top? I'll leave you to think about that, you can make your comments later on. My view personally is to use the soccer parlance. Ireland is a Liverpool or a Chelsea or a Tottenham. Ireland should be asking itself why it's not here. Now if you wanted to know why it's not here that's interesting. This is the Estonia country profile and as you can see it is absolutely a digital nation. I'll leave the slides you can go through the various indicators but in all the indicators they use Estonia scores extraordinarily high. This is Denmark who also score very very highly. You'd be very pleased with that and this is Ireland. So you know there's things obviously that we can rush to fix. There's one prefilled forms so we just don't do enough digitally. We don't encourage enough digital transactions with our people and so on. So some of this you can argue need legislation and so on but there's almost a more fundamental thing for us to fix before we get into any of that debate. So this is what the Estonians would say are the absolute critical success factors to be a successful digital government. So a trusted identification element. Legally approved digital signatures which obviously needs legislation and change of culture and so on. Integrated approach underpinned by a single digital identity. Clear plans to use identifiers and integration for visible benefits. In other words tell us once in the transparent government. So actually in Ireland we've a lot of these things in place. We just need to start to accelerate how we use them. And that's what the public service ICT strategy is about. When I came down in April one of the first things that was asked was are you going to want to rewrite this and I said absolutely not. I think it's an excellent document. I don't think it could have written it any better. But there's five pillars. So Bill the share is basically how we're going to help fund some of the other stuff. So it's about kicking out duplication, doing more together, shared services and so on. Digital first obviously which is about our whole digital front end. Being a data driven government. So using data for improved policy making all of those things. And improving our governance because obviously as you move to a more cohesive model risk in terms of cyber security and all of those things goes up. So therefore governance and stewardship and auditability and all of those become even more important. And then the capability of our people. And again you won't go to any presentation in digital that doesn't touch in capability because it's a key part to being a digital organisation. So what have I been doing? Well I've met all the Secretary-General's, CIO's various other stakeholders. And I've worked with the CIO's and the heads of IT in the department. So we now have an 18 step plan to deliver the strategy which I issued to the Civil Service Management Board in July. And by the end of this month I'm hoping for formal approval to go ahead. Although we're going ahead anyway. So we'll talk specifically about digital. What I found was there's a lot of very good departmental projects. So for example Gardner would say that revenue in terms of how tax is done as a digital services in the top three in the world. And it deserves to be. It's very, very good. The whole passport system is excellent. And I'm sure you've all got examples as well of your own dealings. The issue is that there's a lack of structure and cohesion. It doesn't look and feel the same in every transaction. And it's not easy to even understand the number of transactions you can do digitally. So that was something. We obviously had a new Minister and Minister of State. And the Minister of State in particular has been given a new government portfolio. And he's very keen to take that forward. So when you've got a politician who's on side from the start, that's an opportunity you don't miss. Against that, as I said, there's a challenge of how we do legacy differently. And there's the scale of our investment in existing systems. So some of these existing systems, as I said, we do need to exploit and run down gradually. In that case of just axing them, we couldn't afford the right of cost. So these are specifically the measures need a team point plan to do with digital. And again, for those of you at the back, I'll just cover them briefly. But the first one is we're going to set up a digital programme office. Because one of the things that I became aware of was we didn't have a dashboard. We've got a Minister of State free government, but Ministers need information. They need dashboards to manage. Like anybody who runs a company.  The first thing you'll be doing is setting up a dashboard of key success criteria outputs and key performance indicators, whatever it is. And you'll have green, amber, red and all of those sorts of things. The Minister didn't have that. So what we'll do is we'll start to create a programme of all the things that we're working on and some form of prioritisation, things that might need intervention, things that are going well and so on. So this is initially about let's not stop what we're doing. Let's get stuff out there. The sort of maturity comes after that. Government doesn't have the luxury, as I said earlier, of some more agile private sector companies where you can stop what you're doing, do it completely differently. Government is a big ship to turn. So even starting to get the digital out there will be important to us. We're developing what we're calling a Government Digital Service Gateway. Some people call it a portal. Denmark and Estonia and a number of European countries have these. The high performance ones tend to have them. But the whole idea is if you're a citizen in Ireland and especially if you're one of the, in Dublin, 20% of new citizens in Ireland is a very easy way to transact with government and understand where you go to get certain services and to reach you out through. I'll come back to that because that's an important one for us. A communications plan to make sure the public are aware of what we're doing and the media is aware of what we're doing and maybe the minister's recognised for some of the things that he's trying to do and then the whole working with the Department of Social Protection because we've got the MyGov ID, we've got the public service card, we've got something that is better than anywhere else in Europe which is a safe verification process. I don't know how many people in this room have a public service card but if you don't, I recommend you get one as the minister did in August even just to understand what a great process it is because you literally have to go there and you have to provide proof of who you are and where you live. They take a digital photograph of you, they take a digital signature of you and that can then be used to verify any transaction that you use with government and I noticed the Estonians announced this week that citizens are going to be able to take out a bank account without ever visiting a bank. That's because the government can provide the banks with the proper authentication that they need to let you open an account. Contrast that to the UK model who are behind us and here's just an anecdote. There's a debate going on in Ireland at the moment about how much information a bank should be allowed to have or the banking system should be allowed to have on us and obviously this is all driven by the crash and poor credit and all of those sorts of things. The UK who famously failed with their concept of a public service card because Gordon Bryan insisted on calling it a national identity card and it was scrapped. They have struggled to verify their customers for digital services so what they now do is they do their verification through a number of trusted parties. One of those parties is Experian, the credit reference agency. Experian are used by the government to say that if you lived in the UK, you are who you say you are. Experian will then contact you and say did you know that for 15 quid a month we can actually not only verify your details but give you an excellent credit rating through our advice and all of that sort of thing. Experian actually hold details in the UK of every single financial transaction that people have done. People get suspicious of the model that we have here and where that's evolving to. Sometimes you need to look outside to see that maybe how we're doing it here is closer to what we feel is right but that's the public service card and it's a very laudable way forward. I would say that anyway but it genuinely is. So let's go back to the whole idea of a service gateway because I call this the Amazon version of government and again I'd be very interested in hearing your views about this but if you think of Amazon Amazon will let you go on, buy something and completely rub your details out of their history and that's it. If that's what your choice is of working with Amazon that's absolutely fine by Amazon. They'll have that relationship with you. Now what they'll say to you is if you would like to give us your details and form a relationship with us we can give you a better experience. So we know that if you like Bob Dylan there's a fair chance you'll like Neil Young or we know if you like books by some author if you like a biography on Sportsman you might like the new Branow Drisco biography or whatever it is. So they're starting to give you a better user experience just by knowing a little bit about you. And then the third thing about Amazon is the whole idea. It's almost a dating agency in terms of establishing an ecosystem. So what happens with Amazon and I don't know I'm sure most of you have used Amazon in the past it starts to recommend partners to you that can sell you things that it doesn't necessarily sell you and how it can do that is because it has authenticated you it has your credit card details it knows you're a good pair and it's authenticated the partners to agree that it knows that they're not we're going to readyourbankaccount.com they're robust, reliable and it will give you a guarantee to underpin your transaction with them. So how does that work for government? So I talked about our portal initially being posting towards services but then it's about registration relationship building in government So what does that mean? Well that might mean if government knew that you had a child in its leave insert this year when you logged on to the portal it pushes stuff to you about third level education choices or if your child didn't get the degree choice the university of its choice has it considered apprenticeship schemes has it considered doing things different type of course and so on so it starts to be a much more citizen led experience with government tell us once we use many so this idea about we can start to bring together all our knowledge of you to try and give you a better experience so we're not going to put you through the stress of having to apply for free health care because we already know your entitle to it so we can start to have a much more engaging relationship with the citizen So what does an ecosystem look like with government at the core? We were talking about this downstairs it's a really really interesting concept and I'm sure if I give you one or two examples you could come up with many better ones but here's the best that I could do Imagine because obviously what do we know that Ireland is a place where people want to come and live and work and study a lot of those people come from a long way away so imagine if in our portal we were able to put up to say people from South Korea, Hong Kong or wherever whose kids are going to come to university here a list of recommended landlords people who have been properly audited or properly registered and everything else two things start to happen through that relationship first of all, somebody in Korea starts to get a list of properties that they know are bona fide properties and the other thing is you start to create an impetus for people in the private rental market to start to be assessed to meet the various criteria to start to comply so you start to see an example of where the government in this ecosystem is having a very beneficial impact on the whole ecosystem and I say that's just an example but you can start to see other areas where that would start to work whether it's apprenticeship schemes whether it's anything you're starting to create this environment we're just by doing this introduction government is almost improving the standards of whatever it is it's trying to influence so just to finish off I talked about the pillars of the strategy a more data driven government one of the things that we're particularly interested in doing is really testing what that means and just to give you a for instance I was talking to the two ministers about this last week if you talk about it a very current issue like housing everybody's got an opinion on housing but actually a lot of that opinion is based on what I would call two dimensional data in other words if you take where I live so if you take county Dublin we can probably tell you the amount of people who own their own homes we can probably tell you the amount of people in public sector provided rental and we can probably tell you the number of people in broadly speaking in private sector provided rental or at least authorised provided rental but what we can't tell you is why that happens we sort of generally talk about there's not enough provision of this or there's not enough provision of that but if you think about the number of people who live in county Dublin who aren't indigenous a lot of them have a completely different culture so that's why it's a house ownership than we do and so for us to assume that everybody who's in rented accommodation wants to buy a house and can't is actually a bit misguided and naive and it's the same for things like planning healthcare and schools and so on we assume that everybody who lives in the west wants to stay there but actually I know growing up everybody, a lot of people who came my friends wanted to live and work in Belfast a lot of people want to live and work in Dublin so in some respects we need to think differently about how we plan things and thinking differently is actually asking those people who are affected would they like to contribute to our policy making and when you think of retail now they do this all the time if you buy regularly from Devinham's or Marks and Spencer's or John Lewis or whoever it is they will write out to you and say do you like, we're thinking of putting this in our autumn range, would you buy what material would you like it to be made of what price point do you think it would be what colours would you like so they're into this all the time we need to think how does that affect how we provide government to our people so we talked about increased sharing of infrastructure this is all the boring part but if we're going to fund the change in this we've got to reduce the cost of back office so nobody's particularly interested in back office when it comes to IT but actually government has too many data centres and computer rooms and network lines and infrastructure and licences and all of those things we need to just simplify that, reduce the cost of it take the money we save and put it in the stuff that matters I talked about the capability we need to focus now on professionalism of our other people we need to create an IT people who can think differently and as I would say to them we need to stop being experts in technology and start being experts in ICT enabled change and that's almost come back to traditional things like being good at communications being good at listening being good at planning projects at benefits realisation and so on so it's a challenge for us but it's a change we have to make and then we talked about governance as you put your eggs in one basket you need to be better protecting the basket and getting that basket regularly measured so you can prove to your stakeholders you're doing the best you possibly can to actually manage it for them and if we do this hopefully we'll come at egg when Ireland's top of the charts so I hope that was useful I hope it's a useful start for a discussion and a debate very interested in having one thank you for your time
