Ladies and gentlemen, the early reviews are in. It sounds like the Little Mermaid live-action 2023 film is a massive success. Oh, wow. And you don't have to take my word for it. The people that we trust above anyone else, the ones we hold to high esteem, are those movie critics on Twitter that are hand-selected by Disney to see the movie early and give their thoughts. They're completely vapid and pointless. Let's talk about them right now.  Splash that subscribe button and make sure to like and turn on notifications so they show up in your feed. I do a lot of movie content, reactions, rants, reviews, all things movies. Oh, and to be nice to the critics of Twitter, I went ahead and changed their names so as not to offend. This first review comes from Flounderfan69. The Little Mermaid may have murky visuals, but the above-ground romance works swimmingly. ["The Little Mermaid"] Great chemistry sells the love story, and the songs we know and love are still magical, like the other live-action remakes. This doesn't touch the classic, but it's enough to stay afloat. Two water puns for the price of fun. I love it. I also love that he admits that it's a pointless remake, like all of them are, and not as good as the original. Great! What an amazing use of time, money, and talent that could have gone somewhere else. Like, I don't know, making something new. Flounderfan6969, because the other one was taken, The Little Mermaid is a fantastic re-imagining of a classic tale. He should have spelled tail, T-A-I-L, but we'll keep going. That overflows with style, creativity, and color. I wish I would have known before I started the voice that this guy was British. He used the obnoxious spelling of color, C-O-L-O-U-R. I'm an American. We cut corners on everything, including our words.  Holly Bailey sings and splashes into our hearts with a wondrous voice and performance as Ariel. David Diggs is hilarious. One of Disney's best live-action remakes. Flounderfan6969 says, The Little Mermaid is the best Disney live-action adaptation to date. Holly Bailey is Ariel. Major props to the sound effects team. Good changes. The one new song with too much autotune could watch this versions under the sea all day. It was the highlight of the whole thing. Oof, pretty blunt force honesty from that guy, giving a criticism about one of the songs autotune being a tad much. Watch out, you might lose that Disney presser. Let's press on. Flounderfan says, Holly Bailey is The Little Mermaid. deja vu, it could've sworn, I just read that by a different critic. An angelic voice, the longing in her eyes, the chemistry with Jonah Hauer King, she's flawless. The movie overall isn't, but there's more than enough charm, heart, and adventure there to power it forward. Melissa McCarthy is a deliciously devilish Ursula. Some of my favorite effects work comes in the third act and focuses on her. And Davy Diggs is stellar at Sebastian, a favorite of the film by Far. Let's be honest, it's very hard to screw up under the sea. The song is fantastic. The seaman is always greener in somebody else's lake. Those are the lyrics, right? I got it right. Flounderphilatio says, The Little Mermaid makes it pretty close to being the best live-action Disney movie. However, it still struggles in the villain department. Holly Bailey is Ariel.  I read three of these in a row and they all say Holly Bailey is Capitol IS, Ariel. Are they getting notes? What, this is insane. And I had literal chills throughout her performance. This is a Little Mermaid retelling like you've never seen before, except for we have seen it before and a lot of it looks shot to shot, but okay. And finally, we have Flounderfuckerphilatio6969 with The Little Mermaid is magical. Holly Bailey is absolutely phenomenal. That girl has some pipes. Scottle and Sebastian are hilarious and had me laughing the whole way through. Love the new songs and added plot points. Some CGI issues, but they don't take away from it. Hashtag The Little Mermaid. Okay, well there you have it. Some pretty scathing remarks about the new Little Mermaid. It sounds like one of the songs might have a little too much auto-tune. It sounds like a small portion of the film has some sketchy CG, but overall, this is a fun, beautiful retelling. That's not quite as good as the original, but it's one of the best live-action movies since the last live-action Disney movie since the live-action movie before that. They just keep getting better.  I don't care for really any of the live-actions except for the Jungle Book, which was solid, but that's because it was really its own story. It didn't take a bunch of stuff from the animated classic. It was its own thing. These newer ones, Aladdin, The Lion King, Beauty and the Beast, they have all the same music. They have a lot of the same storyboarding shots and scripts. It's just so empty. The color is drained out of them. The energy's gone. It's a bizarre amalgamation of different corporate overlords saying what should go in here, what color we make one character to bring in more people, what gender we make someone to bring in a different audience. It's all about getting in as much money for these soulless trash remakes as humanly possible. Now, The Little Mermaid could be fantastic for all I know. I just have a really hard time trusting any of these early reviews, but I'll see it, give my honest take, my honest opinions, tell you if it's a fun movie for you and the family to go see and we'll go from there. My guess, it'll be perfectly harmless and fine to bring your kids and waste a couple of hours. A grown man, yeah, probably not the target audience for this one. I don't care much for the original Little Mermaid. It's fine. It's a fine colorful movie. I come out as a movie critic and someone that just likes classic Disney doing new things, pushing the envelope, making new stories, putting twists on old ones, but we don't get that anymore or we hardly get it anymore and it's sad. Let me know your thoughts though.  No, that's not true. I've actually liked a lot of movies that have come out of Hollywood lately. This year has been particularly solid. Hopefully Fast and the Furious 10 and The Little Mermaid can keep that trajectory going. I have zero faith in that happening, but maybe I'll be pleasantly surprised. Leave a comment with your thoughts. Please like the video, subscribe if you haven't and hopefully I see you next time, C spelled S-E-A cause water puns.


Good evening everybody. I am Rajesh Kushalkar. I am heading the team for the clicker. What is the normal classroom scenario? What do we have? The teacher comes, teaches and goes away.  Just becomes people teach and go. The teacher does not want to believe whether the students have understood the topic or not nothing. So this is a normal scenario that is there in the classroom. If some of the teachers who are more interactive, they give assignments in the classrooms. The assignments are distributed in the form of papers. The assignments are collected. Then there is a TA who gives correct the teacher himself has to correct the answer sheets and enter the marks. Sometimes while entering the marks in the final sheets, he miss out some numbers. And a lot of headaches are there. So what is clicker? Clicker is also known as students response system, audience response system or classroom voting system. It is a very small handle device just as a TV remote size or a mobile phone size with a number pad on it. And students can participate in a classroom using these devices. So how a student is interacting? All the students are having the device called as clicker. Each clicker has got his own ID. This ID is mapped with the clicker software on the respective computer from where the presentation has been uploaded. And there is one receiver connected to the system. So moment the question is flashed, the responses are given by the students and the receiver collects it and it is given to the system back. So as I am saying how it works, the students are allowed to participate in any quiz session conducted by faculty. Responses are submitted within the minute, same way. Advantage of using clicker, assigning and grading reports, providing immediate feedback to the instructor allowing modification or revision in teaching. You must have come across situations like that the teacher teaches and goes away. So how we understand whether the classroom has understood all the topic whatever I have taught in this one hour lecture. So what faculty does? He divides the class session in two or three sessions whatever he wish. Suppose today I am going to teach something for one hour. So I divide the topic into four parts, 15, 15 minute each. I discuss on some of the topic on 15 minutes and give a quiz related to that topic after the 15 minutes. The students are having the clickers with them. The quiz has been shown and the responses are collected. So faculty immediately comes to know, yeah 50% of the people have understood given the right answer and 50% have given the wrong answer. The immediate feedback that the faculty is getting is this. 50% of the classroom have understood that 15 minutes whatever I have taught. What is the immediate reaction? What I will do? I will ask the class to take, discuss among yourself and I will conduct the same quiz again. But when I do that, I see there is a drastic change in the correct answer. It is almost 90%. This is the thing what we have conducted in IID Bombay and seen the results. Because when you discuss amongst your friends next to neighbors and all this thing, understand the topic and immediately the answers are changed. It is not key, yeah I want to correct the answer and give it like that. So people understand but if I still find it key, no only 60% have given the right answer and rest 40% have given the wrong answer, then the faculty can decide himself whether I have to re-teach the same topic again or not. So you get immediate feedback from the students. There are many shy students who do not answer. Like you must have seen in lot of class, in your class also. If anybody ask a question, if there are any questions or anything, nobody raise the hand. There are still doubts in their mind. But when I give a quiz and if you are not having any clicker devices with you, still only the bright student or anybody who are confident in themselves, they will raise the hand, you give the answer. But what about rest of the people? Why? Because they are shy, they are not able to answer. So I am not able to get whether these people have understood or not. But with the device clicker, I come to know each and every person whether the student have understood or not. That is why clicker allows all students to answer all questions at all the time. Now this says there are people, if this gentleman is conducting a meeting, he is a manager and rest of the people are just listening to his talk and they are saying no, it is not going to be done in their mind. But what is there on that tongue? Yes, yes, yes. So what is in their mind? It is not coming properly. Why?  So I can pack you afterwards somewhere. But what if the identity is kept, not known. But immediately that manager knows, this many people are offered it and this many people do not want it. Basically how it started in IITB? Actually Professor Fater and Professor Kutcherkar were having a talk almost around 2006 and all this time. So this idea came up. Actually this is a very old technology which have been used in US and many European countries. But the technology is too costly right now. It cannot be given to all the colleges across India. In fact it is not been used in US also for all the colleges and schools. The first design was made by the interns just like you from Jaipur in 2008. It was a very big board. So this big board converted into this small size was very difficult. So we took the design forward and design the clicker version 1 and clicker version 2. In year 2009-10 we have designed this clicker version 1. As you can see this is a simple remote control box just a TV remote size. I have just the feature was single objective answer. LED indicators. So I have an option of A, B, C, D, E. If a question is having only options A, B, C, D, E I can answer it. I have this few LEDs which are here which indicates me whether my device is on, whether I have the answer I have pressed it or locked or not and I have received acknowledgement or not. So these are the three LEDs which indicates that part. In 2009 we have conducted 2010 in fact we have conducted using this clicker for almost around 800 students in IITB. The response was too good. The students were more excited the attentiveness in the class. As you can see whole class 800 students can faculty look at each and everybody. There is somebody at the corner in fact somebody in the front bench also sleeping. I have flash a quiz. Immediately I have to get the answers. And if the quiz carries mark then people even in IITB even people cry for half of marks because the grade depends on that. So you must be very much so this device makes the students very attentive in the class also. So this display was having some limitation as whether my answer is going or not coming or not the LED indications whether I have pressed A or whether I have pressed B. It was not known the students were getting somewhat confused. So we have taken some feedbacks and decided to work on version 2. Version 2 is something like this. So it has got this many features with it. So single objective answers like A, B, C, D whatever options are there. Multiple objective answers like the answer is A, C, A and C or I can arrange in a proper manner A, C, D, B numerical with decimal. I can point the numerics also. True false, yes, no for polling, hand raise. This is something new which we thought to implement in version 2. What is this hand raise is about? Same as when you teacher is teaching somebody raise the hand, he ignores it or he gives the answer or 10 people are raising the hand only 1 or 2 people get the chance to answer it. So in this one what we have happened? He on the faculty screen, so whenever the person is raising the hand, he presses this raise hand button. On the faculty screen the name of the student comes. If this particular person has raised the hand, like that I can have 10 people of students who have raised the hand. Now I see this number 1. I will say you can get up and ask the answer question. I understand the question. I give the answer the moment I finish my answer. I see out of that 10, when I press again the raise hand because out of the 10 people it might be possible 8 people were having the similar doubt what that first person was having. So I see that 10 reduces to 2 because those people are understood the same because they were having the same doubt in their mind. So for me also it is 2 now. So I will ask that person and the doubts are clear. So with the use of alphanumeric display the answer was displayed what keys I have pressed. I have received the acknowledge and all this thing was visible on the display. This display was having feature more features just like receiver signal strength. What do you see in your mobile the antenna indicator? How much is the receiver strength that I am having it? The battery indicator and all those things features which are available. Course ID which course I am attending the course ID also is displayed on the system. Limitations in v version 1 and version 2. There is lot of communication issues for large networks. If I increase it to as I have told you we have tested with 600, 800 students. But it was not full proof that all the 800 students or 600 students receivers was able to collect it. There was a lag. Communication error was there the packets were not reaching properly. So packet was getting lost. All the same. So this was a major limitation. All responses were not able to collect it full plate. Assistant was required to set up the device. So this has to be connected that wire has to be connected. So it was not a simple USB dongle device kind of thing. You connected like a pen drive and start using it. And there was a switching between the presentation window and a clicker software window. So whenever I am to conduct a quiz I have to switch to the clicker software window, conduct the quiz, take the data then again come to the presentation mode. So switch was required. So and central desktop, central server desktop PC was required for the communication. So these were the limitations and I will say for the version 1 and version 2 this desktop PC was a must required for operating the clicker software. Then year 2011, 12 we went for the clicker version 3. During this time we had got this thing for developing on Akash tablet. So it was a web based architecture. It was told this device the version 2 was coming to be something around 1100 rupees. The bill of material was around 1100 rupees. The Akash tablet government has told to sold at around 1500 rupees for the student. So we thought we will use Akash tablet as a device as a clicker only. Advantages, you got a 7 inch screen on it. Lot of things you can do with it. I was just having 16 by 2 alpha numeric display on it. Just 16 character by 2 lines in version 2. Here I am having a full pledge 7 inch display. I can do lot of things. I can show the quiz itself on the tablet and do lot of things. Communication issues were there in version 1 and 2 where we were about to develop our own protocol to communicate between the receiver and the devices. Now tablets comes with the Wi-Fi device. Wi-Fi device is more robust. So all the packets sent by the system are received and same features what we have seen around 6, 7 features are to be implemented in version 3. So this was the diagram. The instructor comes as you are saying, this is the instructor he see. He is coming. He is connecting to a central server. He is logging to that. Students using tablet is logging to the central server. The students using tablet through access point connects to the same central server. Faculty has got his own login which is a master device or a quiz controller. Suppose today I want to take a lecture in which I have 5 quizzes. In this one hour session I decided to take 5 quizzes. So the moment I come in the 5 quizzes are uploaded. But the students when they log in they do not see the quiz. Whenever the faculty or instructor instructs he now display quiz 1. That time only the quiz 1 is displayed to all the students. The questions is displayed on the projector or we can display it on the tablets also. The responses are collected and the graph is shown immediately on your projector. What we have done? We have completed with the web based version of clicker. This whatever the diagram I have shown you, we have completed with that with distinct login for faculty and students on the same URL. Each student is recognized by this own user ID roll number. Now clicker devices like version 1 and 2 it was a pure hardware device. So each device was having their own ID. This ID was mapped in the software with roll number. So here what we have done? We have mapped the MAC ID of the system tablet with the students roll number. So each student is recognized by the tablets MAC ID. Tomorrow it happens I will give him MAC ID. The tablet he changed my user name and try to login. It will not allow him to login because it is mapped to this particular user roll number only. So in my database it will show me the conflict and the other person is not allowed. What has to be done? We have to integrate this to a learning management system like Moodle and to LDAP servers also. These are the two things which are remaining we have to do. What is your project? This is slightly interesting because whatever we have done we have to do something very different. Everything was web based. Imagine you do not have a web server nothing like that. A tablet to tablet communication. So developing a clicker software using Android platform because the tablet is running on Android platform. Tablet to tablet communication master or a quiz controller tablet. So it is outside not a tablet software I will say. The faculty software or a faculty tablet will be different which has got all this feature for conducting the quiz and conducting the quiz. Students tablet on which they will able to view the questions and answer them. How to get associated with the master tablet? This one how a central server was communicating? The students were logging to the central server. Instructor was logging to the central server. Now just imagine this server part is not there at all. So they have to be communicate directly and how to display the question and response on the students tablet. So this is basically I get a question. I place a press the answer and after a time elapsed immediately I should see the responses on my tablet also. See how many people have given what answers and all the same. A graph how to store all responses on the master tablet because all the students are going to associated with the master tablet. So all this record which comes has to be stored on the master tablet. Report generation has to be done on the master tablet. Exporting the data to a central server. The master should have a facility to export this data to a central server. Import quiz from a USB drive. Suppose I go at home I prepare the quiz. I come in the morning I just connect the USB drive to the tablet. I should able to import the quiz. Raise hand feature with audio and video. This is one of the person. B.Tech students have done this project for controlling a robot using android tablets. So on the tablet there is an android phone and a person is having, a student is having the android phone in his hand. He is controlling the phone via phone the robot and the robot is transmitting the video. Whatever the wherever that robot is going it is transmitting the video on that phone. So that application we can definitely use in the raise hand situation. This is the server less software architecture for the tablet. The instructor is their access point and students. So here you see there is no central server. Why this architecture we have chosen? Because there are many schools, many colleges which are not enable with all this projectors, PCs and all this things. But definitely as sir has also told is so many tablets are going to be produced and it is going to be distributed to all the colleges. So how they are going to use it if they do not have this kind of facility. So instructor in a classroom communicates with the students and get the responses and show that the quiz is shown directly on the tablet. So you do not require a projector also. Because this is a fresh software from scratch it has to be developed. There are lot of applications and everything we have already done for the web based. Now everything has to be moved to tablet or android based. So it is the same as IIT sorry in 2008 the interns like you who have come to develop the clicker. So it was from scratch. So they have developed it was a very big board. So come to that mobile phone size was a very difficult task for us also. But at least a prototype or anything can be done. This can be taken ahead. Any questions? Thank you.


What's up guys, EvilDeer here, and today I'm going to do a response to a very old blog post. Now the reason I'm responding to this blog post, well there's actually a few, but the main one is because I just received a link to it literally like a few days ago. I received links to it before and I responded privately to the person who sent me the link before about my ideas regarding the content of the post, but I decided you know what, I'm gonna make one video, slap it all in there, and then just publicize it, and then if anyone asks me in the future I'll go hey go check out my video. Now this is going to be a long response. Nothing is ever just black and white. Now normally I wouldn't respond to a blog post called Why I Won't Learn Esperanto, French, English, whatever, because you know that's a personal opinion, you don't have to go learn anything, but there is a fair few misrepresentations about Esperanto within this article, so I feel like I'm going to respond to those. Whether you want to learn something or not is up to you, but I can respond to the misrepresentations. Now the guy who wrote this, Donovan, I think that's how you pronounce his name, has actually engaged with me previously on my YouTube channel. There's one of his comments that was more, but I can't find them, maybe they were deleted, whatnot, but anyway it seems like generally not an ass. So that's a good thing. I'm not going to go attack this guy, but I am going to present his biography, mainly because I feel like we have so much in common, it's kind of crazy. The blog post was posted on the website, the Mezzofanti Guild, named Donovan as I said. Now he's from Australia and he's travelled the world for over 14 years. I'm from Australia and I'm excited about that because you know, bloggers and YouTubers from Australia are quite rare and when we bump into each other and discuss a topic that we're both interested in, it's even more rare. We're a massive country with a very small population and it's super rare that I found someone who's a blogger who knows anything about Esperanto in Australia, so this makes it kind of special for me. Anyway, he's travelled for 14 years, don't know if that's consecutive or not, I've done a lot of travelling myself, not 14 years worth. Now he says here, like most people though, I had to study a language in school, five years of Mandarin Chinese. I was the same, I didn't have to study Mandarin Chinese, I had to study Japanese and I did five years in school and I understand where he's coming from. The Australian education system regarding the teaching of languages is atrocious. It is terrible, you basically learn nothing. At least it was during my generation, I'm assuming his generation, maybe it's changed now but back then it was terrible. I did five years of Japanese, didn't learn anything, but I have to kind of admit I was in the class mainly for the girls. It was a confusing time during my youth, you know, my teenage years. There was a lot of testosterone going around, a lot of hormones, whatever, so I didn't learn Japanese. Now he says after school, did my undergraduate degree in theology, it was here that I realised for the first time just how fun and exciting languages actually are. Hey, I agree. After I left school, I joined the army, did six years and that's when I bumped into Arabic. I learned a little bit, didn't find it that interesting. I mention Arabic now because he is actually fluent in Arabic. It was the first language he got fluent in apart from English, so I figured that's a good starting point. Anyway, after that I bumped into Esperanto and that's when I realised that languages can be fun and exciting. So overall, me and this guy are very similar. The only difference is he's a Christian and I'm an atheist. I just need to say I'm not going to respond to every line in his article. For example, the first three paragraphs I feel like are just fluff. It's like how, you know, a YouTuber has 30 seconds off logo spinning around making magical sounds. I feel like the first three paragraphs or so were basically just fluff. They weren't really needed. Okay, so the bloke who created it, Esperanto, Ludwig Zamenhof, developed a political and religious philosophy and then he's bracketed a cultish offshoot of Judaism that looked more like something straight out of the communist manifesto. So obviously this is an opinion piece but I feel like he's bracketed the insult. He's kind of like demonising Esperanto speakers by linking them with things that make it look bad in a sense. So first up, I'm going to break down each part and explain why. So he says a cultish offshoot of Judaism. He's mixed up a few different things here and I'll explain the other things later but I will say this right now. When people call something cultish, they're not saying, hey, that's a secret religious organization most of the time. They're not saying that. They're saying, hey, that's something you shouldn't look into because if you do, you'll get sucked in and that's the end of it. We'll never see you again. You'll end up worshiping something. So he's kind of implying that Esperanto is in some way a cult, which is definitely is not because there's no religious aspect to Esperanto. There is no God to worship. There is no higher being or anything like that. It's literally just a language and then he says it's an offshoot of Judaism. I'll go into this more later. So first up, Zamenhof was Jewish but the vast majority of Esperanto speakers aren't Jewish and probably the majority are maybe Christian but I'm not even sure about that. There's a lot of atheists, a lot of Christians. There's a fair few Muslims as well, but not that many Jews that I know of in the Esperanto community. They do exist, obviously, but not that many. And then he goes, it looked more like something straight out of the communist manifesto. So now he's implying that Esperanto is not only a cult but it's also something that's politically in line with the communist manifesto. I'm going to lead that up to you to judge. Now we'll say one thing. I find this quite strange coming from someone who's learned Arabic because a lot of Arabic speakers are demonized in Western media, even in Chinese media, they're just demonized in general, due to what's happened in the Middle East and due to terrorist attacks around the world. So someone who's gone out of their way, learned Arabic, I believe would be more aware of the hardship that they've been put through by certain members of their own community causing all these issues. So I feel like if you were within that situation, you would feel less inclined yourself to throw these types of insults upon another community, but that's just me. So I'm not going to go demonize every Arabic speaker due to the fact that some Muslims have gone and blown up people, but I feel like he's kind of painting the entire Esperanto speaker community as something cultish and et cetera, et cetera. Anyway, let's go into what I think he's trying to talk about. So there's three aspects to this. Esperanto, the internal idea and homaranismo. So I'll speak about Esperanto in the internal idea first. Esperanto is basically just a language. It was created prior to 1887, but the first book on Esperanto was published by Zamenhof in 1887. Zamenhof published the foundations for the language. He didn't create the entire language. In fact, he created only a tiny portion of the language. And from there, it evolved into this full-fledged language we have today. The first book was published by Zamenhof. And in the first book, he stated three, three ideas for why he thinks Esperanto is needed, why he basically created it. So let's go through these ideas and see if this sounds like something that's cultish to you. So he said, to render the study of language so easy as to make its acquisition mere play for the learner. So basically he wanted to create a language that was so easy, it would basically be a game. So what he was talking about was gamification before Duolingo made it cool. So he wanted a language that was just super easy. Second one, to enable the learner to make direct use of his knowledge with people of any nationality, whether the language be universally accepted or not, that or not is important for later. In other words, the language is to be directly a means of international communication. Very simple to understand. He wanted to create a language that could be used for international communication between people who didn't share the same language. Those first two points are very simple to understand. The third point needs a little bit more historical context. So I'll read the third point now. To find some means of overcoming the natural indifference of mankind and disposing them in the quickest manner possible and en masse to learn and use proposed language as a living one and not only in the last extremities and with the key at hand. So let's break down what he's talking about here. This refers to the internal idea that exists within Esperanto community. So the Esperanto community has these three things that are the internal idea, but this one's more so the last. So there's three things he mentions, natural indifference. So he's talking about the historical context in which Esperanto was born. Esperanto was born during a time in history when Poland was ruled by Russia and the whole of Europe, okay, was divided based on language. So if you spoke French, you're French. If you spoke German, you're German and we don't like each other. That's just how it was. So the natural indifference was extreme tribalism and nationalism, which was just rampant in society. And this was reflected in the town of which Zamenhof grew up in. Basically those Poles, Germans, Russians, Yiddish, and no one spoke to each other because they all belong to different groups. They were all different ethnic groups. So this was the extreme tribalism or the natural indifference of society. And he wanted to dispose of this. He also wanted to create a living language. Now here's the idea of a living language and the idea of a living language for some groups of modern Esperanto speakers is quite different. Zamenhof wanted to create a language that would be learned by everyone, eventually almost as a native language, but we would speak, say in Australia, I'd speak English. And when I went to China, I wouldn't speak English, my native language. I would swap the Esperanto and speak Esperanto with an Esperanto speaking Chinese speaker. And when they came to Australia, it'd be vice versa. So we would keep our native languages, but we would also have a secondary native language Esperanto. Now a lot of modern Esperanto speakers are like, no, no, no, no, Esperanto is the second language and you have your native language. So they're against the idea of anyone learning Esperanto as a native language. But you can see Zamenhof's idea in the fact that he taught Esperanto as a language to his children. And a lot of early Esperanto speakers took on this ideal. But basically what happened is in the early history of Esperanto, the idea is swapped and less people start teaching it to their children. A lot of people still teach it to their children and I feel like a lot more are starting to now, like some of my friends are. So there's been an evolution in ideas about should Esperanto be a native language or not, but he believed in a sense that it should be. The last part he says the key at hand, this is not some mysterious, cultish thing. It's simply talking about the Nualibro. It basically had a key within it. And the key was these are the words. This is the grammar. You can use this as a cipher to transfer your English to Esperanto, write a letter, send it off to your friend who would use their key to decipher it back into, or back into like whatever their language is, Russian. So it was basically like a really poor version of Google translate. And eventually he hoped that when people got good at that, then they'd speak it, that evolve on it and never become its own language. In fact, Esperanto was probably the first crowd source language, the first open source language, because when Zamenhof published it, he said, hey, I created this, but it ain't mine. Don't come to me asking for questions. You guys figure it out. He basically went, I'm not, I'm not the like the leader of this movement in any sense. But the funny thing is I've given you all of this historical information, but the vast majority of Esperanto speakers don't know anything about this. It's like those people who know a ton of information about the constitution of the US and the founding fathers and what they think and all that type of stuff. You go ask the standard person on the street what the founding fathers thought about this and that, or you ask them about the constitution. And they'll have a vague idea about a couple of things here and there. So that's what the Inua Libido is to Esperanto speakers. It's like the constitution, but without the legal backing that comes with it. So it's kind of like this document that we look at historically and it impacts on certain aspects of the Esperanto community, but there's no legal force behind it. So realistically, it doesn't have that much of a influence in the modern Esperanto community. So the next thing he spoke about was homaranismo. So homaranismo is something completely separate to Esperanto that Zamenhof created. So let's talk about that now. Homaranismo is a philosophy that Zamenhof created and the idea was that everyone's religious. During the time when Zamenhof was like alive, everyone was religious. Everyone belonged to some religion and the religions were almost linked with languages and the infighting between the religions was based around these religious slash language linguistic groups. And he kind of wanted to find a solution to that as well. So he was working on two things at once. So he created homaranismo and it was originally based on hillialism. I don't know how to pronounce that word. Anyway, it's like a Jewish belief system. He based on that originally and then he went, ah, no, scrap this. So he completely ditched that and he created his own belief system. And basically the belief system is a philosophy. So here are the two main core beliefs of homaranismo. And I'm going to, these are in Esperanto. So I'm going to translate them to English on the fly. So my translation may not be like the best, but I was too lazy to just translate it because there is no English translation. So he says, I am a human and the entire human race I see is one family. The division of the human race. See, I put division in green. The division of the human race into different like enemy ethnic groups and the ethnic religious communities I see as the biggest unhappiness, the biggest unluck. Okay, which sooner or later must disappear and whose disappearance I will accelerate according to my ability. So what he's saying is he regards the division as the biggest worst thing that's happened, not the ethnic groups, not the religious ethnic groups, but the division between those groups. So he supports the ethnic groups, but he hates the division that's been formed between them by people using them to their benefit, you know, to their own personal benefit. And he wants to make that disappear, the division. I'm pretty sure anyone in the world would agree that division between ethnic groups is a bad thing and anyone who proposes creating division is just being bad in general. Now the second point is I see in every human only a human and I treat every human according to his personal worth and actions. Every offence and oppression that's in green of a person because of that, he belongs to a particular ethnic group or language or social class that's different to me. I see as a barbarity. So he sees the oppression of people as a barbarity. So Zamenhof is all four ethnic groups. He believes in the diversity of the human race. I think anyone who looks at this and associates this as cultish or as something that belongs to communism really is misreading it. Now maybe on its surface communism and this have something like aligned with each other, but this is just as much aligned with the beliefs of Christianity or Islam, at least in my eyes. So anyway, that's what he actually believed regarding Homaranismo. Esperano was separate and in fact, as I said, Homaranismo died. It would probably been better if it survived, but it died off. So he believed oppression is bad, division is bad. So another thing this person says in their blog is Esperantistan is an ideologically homo-genant, I can never pronounce this word, I'm not even going to bother, landscape. So he's basically saying that everyone in the Esperano community thinks exactly the same. First off, I just want to point out one thing. He said Esperantistan. I found this quite a strange word. Now the Esperano word for an Esperano speaker is Esperantisto. So he obviously knows a little bit about, you know, word formation in Esperano, but then he's used this English ending stan, which is only ever used for words around the Middle East or maybe like ex-Soviet countries. I'm wondering why he did that. There's only one of two reasons.  Or two, he's thinking more along the Bogan English thinking. A lot of Bogan like English speakers, especially in Sydney, add stan to an end of a place name to make it sound like a war zone or something that's just bad and generally not good to go to. So I don't know which meaning he's aiming at here, but you know, it's really not that important. The actual word for the Esperano community would be Esperantuyo. So you can use that in future blog posts. Wherever you travel, you meet people of all different persuasions. No matter what language you learn, you'll meet speakers all the time from the far left to the far right of the political spectrum. You'll also meet non-believers, nominal believers, the devout and the extreme, Esperano being an ideological tool that it is opposes this. So he's basically saying Esperano has one belief system. We all follow that. So the question is, are modern Esperano speakers all either logically the same? Well, no, because I'm proof of that, even though that's kind of anecdotal. Let's start with myself because I know myself. I am the most popular Esperano YouTuber in the world. That's saying a lot for a small community, but I am, well, it's not really saying that much, but I am the most popular Esperano YouTuber, not kind of like trying to flout it or anything. But the reason I'm pointing this out is because I probably go against the trend of a lot of groups.  I in fact think that communism is an ideology that has resulted in the depths of millions is terrible. It sounds good on the surface, but once you actually try to apply it to humans, which in essence are broken, like humans are easily corruptible, it becomes terrible. So I'm actually a capitalist. I believe that, you know, we should work for goods and we trade goods based on our own means without interference from others. I don't believe in big government. I feel like small government's the way to go. I believe some regulations required, and I'm totally not religious. So I'm probably more right leaning in a lot of ways, probably in the majority of ways. Now to give you an idea, my local Esperano group, which basically consists of my friends, we are people who fit into pretty much every political ideology. Now in Australia, he's aware of this, but I'll point out for everyone else. In Australia, there's three major parties, the Greens, Liberals, and the Labor. So the Greens, you're probably aware of what they are. They're basically far left. Then you got Liberal. Liberal's kind of like our version of the Conservative Party and the US. So they're kind of like right. They're like leaning towards the right. And then you got Labor, which is like our version of the Democrats, which are leaning towards left. So I vote Liberal because I think their policies in general are just better for us as a society. Now in my local group, there are Greens voters, there are Liberal voters, and there are Labor voters. And we're all Esperano speakers and we all get along fine. We have our political debates, but that's about it. We are not all ideologically the same and definitely are very different in a lot of regards. Now I put in red here that the only thing every Esperano speaker agrees on is that we speak Esperano. And we can't even agree on that most of the time. If you look at my YouTube comments, often I'll have YouTube comments like, you're not speaking real Esperano because you're using this or that made up word.  It's the same thing that happens in Esperano. There's always like a grammar debate somewhere. And that's pretty much just how it goes. So the only thing Esperano speakers agree on realistically is that we speak Esperanto or at least some form of it. So the idea that we're all the same is a bit strange to me. And he used one reference to one person's anecdotal experience about going to an event. Now the thing is with events. Events anywhere in the world are representative of the people who run those events. And if the people who run that event are all left leaning, then the event in general is going to be very left leaning. If all the people who run the event are very right leaning, the same thing happens. So if you just happen to go to an event that sounds interesting, but unfortunately it's being politically tainted by the people who run that event, then that means you're going to feel like everyone around you is of the same political persuasion. It's not true in the Esperano community. It's not true in general. I think that's probably a bad example. Now he says, not only does it have no culture, but its inheritance are delusional. Esperano has no country or geographical ties to an ancestral homeland. Unlike natural languages, you don't learn Esperano because you're fascinated by country, people, group, or location. Outside of a few crackpots who decided to turn their kids into circus acts by raising them with Esperano as their first language, it has no intergenerational identity or national tribal history. Okay. So before I break into responding to that, I'm just going to read the follow-up part he wrote. To which some people say Esperano does have culture because it's got music, food, events, literature, and he responds with, I think this is incredibly shallow and a poor understanding of what culture actually is. So let's go back to the previous spot. He says, Esperano has no country or geographical ties to an ancestral homeland. That's true. We don't have a country. There is some geographical places that are linked very closely to Esperano. For instance, the Esperanto Urbetto, which is a small town in Germany, I forget the German name. Someone will put it in the comments. Basically there, Esperanto is part of the local community, all the signages in Esperano, but it's used more as kind of like a tourism thing. So it's not really like a thing that's been passed on generation to generation. So I agree with him Esperano has no country or geographical ties. Okay? That's the extent of my agreement. Unlike natural languages, you don't learn Esperano because you're fascinated by country, people, group, or location. I don't necessarily learn a language because I'm fascinated. Like for instance, I learned Chinese not because I'm fascinated with the country, the people, the group, or the location. I learned Chinese because I needed to speak with my wife's parents. Afterwards, I became fascinated in the country, people, and the location, but I didn't start learning it because of that. So this is a flawed assumption that people learn language because of this. It has no intergenerational identity or national tribal history. So Esperano was 130 years old. So it can't develop a very big tribal history. I'm going to call it tribal history to keep it in line with what he's saying during that time. But there is fourth generation Esperano speakers.  They do exist. We've actually got one here in Sydney. She, not fourth generation, I think she's like third generation.  And she has basically photo albums going back to her great grandma, where she's showing pictures of them at Esperano events, how they met, you know, Esperano pass along through the family. It's the same thing when I went to Germany, I stayed with an Esperano speaking family from Moonech. And they have Esperano and their family for a few generations. And if you told them that it wasn't part of their family history, you would basically be insulting them because it's how their family even formed a couple of generations ago. Now, Esperanto has not just a tribal history. It also has like tribal pain in a sense. So I've got this book here called La Dunjera Língvo, which means a dangerous language. And it basically details all the times during history, Esperano speakers have been killed due to the fact that they speak Esperanto, or they have been locked up because they speak Esperanto. It talks about how Hitler killed Esperanto speakers, Stalin killed Esperanto speakers, how the Japanese locked them up in World War Two. It goes into depth. And these types of things for me are what glue culture together, the sufferings and the shared culture. So this is a book. And now I'm going to quickly just place in a short video of me walking around the Esperanto library. I know he considers literature to be a shallow example of culture. But for me, literature is a perfect example of culture. Now I'm showing you the Esperanto library here. As you can see, there's lots of books. I'm not going to put in too much. You can search for this in my YouTube channel if you want more in depth videos. Now he says a good definition of culture is something that's intangible aspects of human societies, patterns of behaviors and interactions, cognitive constructs. For me, this definition is so abstract that I'm unable to define culture through this definition. So if I was him, I would have presented an example of this through Australian culture. So what are the intangible aspects of Australian culture, whether the patterns of behavior of Australian culture and interactions and the cognitive constructs? I can't even think about that for Australian culture. So I definitely couldn't think about that for Esperanto culture. I feel like this is a meaning that's so abstract that it's lost its meaning. Anyway, maybe there is some way that you can do this. You would have to be a neuroscientist to figure this one out, I think. So in the end, he says the original goal for Esperanto in fact conflicts with the very nature of human cultures to serve, to separate and distinguish humans as unique groups. Well, remember what the original goal was according to Zamenhof? It was to create a tool in which we could contact each other across culture. It was not to replace culture. Now I've been speaking about Esperanto culture for the last five minutes or so. So you're probably a bit confused. Not everyone follows what Zamenhof originally intended. In fact, the vast majority of the Esperanto community do as they please. And although Esperanto was created with an original goal by Zamenhof over 130 plus years, it has evolved into many different directions and people use it for many different reasons. So there is still a few people who use it as that original tool for international communication and there's lots of people like me who simply enjoy the culture that evolved out of Esperanto. So he also says that Esperanto evangelicists, I can't even pronounce that word because I barely ever use it, aren't just passionate, they're fanatical. So yeah, the extreme thing. Discussing Esperanto with an Esperanto is like discussing theology with a Jehovah's Witness or animal rights with a Peter activist. Now I know he's going to use this video as an example, so I'm just going to point this out. You can go learn whatever you want. I don't care if you learn Esperanto.  If you choose to, great, you know, do it for you if that's something you enjoy. But I'm not saying you need to learn Esperanto. And I think the vast majority of Esperanto speakers are like that. What I'm trying to do through this video is to provide an interesting perspective into a unique community. And do we worship Zamenhof? Because through this whole thing, he's trying to present Esperanto like a religion. And I get the feeling that he's saying that we worship Zamenhof. Now, there are probably a few Esperanto speakers that do worship Zamenhof. Just like there are a few Americans who probably worship the founding fathers, there is always a fanatical person in every community. Do we define the communities based on those few fanatics? No, we don't. Okay. And to give you an example here, Moyosuyo. Moyosa means cool in Esperanto. Uyo, as I said previously, is kind of a country. So Moyosuyo is a cool country. What happens a lot is Esperanto speakers, when speaking in public, people hear us speaking and I'll go, hey, what language is that? Because it sounds so weird or like foreign to them. And we'll explain what it is. And then we'll often get like mocked. Like people will just mock us. They're like, why would you speak that language? Why not learn a real language? Even though there's no definition for a real language. Anyway, so what Esperanto speakers often do in public is we say, oh, we're from Moyosuyo. It's just a small Eastern European country. And then that would be the end of the conversation just due to the fact that we don't want to have this have this discussion every 10 seconds. So the idea that we go fanatically around and go, you must learn Esperanto speakers, you must learn Esperanto is it's kind of strange. Okay, so I'm just going to finish this off. And he says Esperanto has failed. Not that we needed it anyway. I'm going to leave you with the quote from Zamenhof, from the Anua Libre de Esperanto, the first book of Esperanto, to enable the learner to make direct use of his knowledge with people of any nationality, whether the language be universally accepted or not.  We use Esperanto for many different reasons. Some might use it for international communication as Zamenhof proposed. Some like me use it because it's an interesting cultural thing and all my friends speak it. Some use it because it's a family language. Has it failed for me? No, I found it interesting. I've used it in international communication. I make money through Esperanto and my friends speak Esperanto and my children probably will speak it too. So for me, it's just an interesting thing. And it's part of my personal culture. Has it failed to become the international language? For some people like me, it's worked as an international language. For others, no. So anyway, that's the end of the video. Just wanted to give my input on this. Sorry if it's extremely long. And if you liked this video, you know what to do. Like it, share it around, sub to the channel if you haven't already. And I'll see you all in the next video. And I'll leave you with a warning. My future videos are pretty much all going to be in Esperanto.


Oh the the hair box. Did you see the delay on that hate? Oh, it does not matter because we got the hard knockdown We got to keep the pressure up How's it going everybody? Dato doi here with another round of Dragon Ball fighters ranked matches and this time we're taking it way back way way back To the OG days when I used to play this team and call it haha. It's a volleyball team But now you look at it. You're like man.  It's fun memories looking back, but obviously nowadays these characters are Kind of next level Boom, let's get a sliding on with gohan. Let's just fake a beam go low. Oh, that did not work out That did not work out as good as I had hoped But if it had Man, how cool would I have felt them down tech? Oh? overhead All right again again not too threatening All right, we can just go straight on the gohan Let's hurry up try to oh No, we should have taken a more defensive position there Who if we had backed up and waited for the down heavy that would have been sublime down tech All right, we're down taking too much of this one. Oh that crossed up I definitely did not think he would clear our heads, but this man is clearly Participating in a different summer Olympics event than I am you said the TN assist that was good Switch.  Oh That was did anybody else see how seconds away from death. I was because I definitely did That was a bad assist Okay That's not working. That's not working. So let's just power up and call it a day. Oh God he should have punished me there He should have punished me and because of how afraid I was that a punishment was coming No super-dash. Oh, I did block it. Nice. I definitely you know what? We're just gonna go ahead and say I definitely blocked that. Ah Darn it. Oh try to cross me up again.  Y'all ever heard of the snapback meta? Block that level three. Okay. Oh, yes, we go low. We go low from time to time, baby Uh-uh-uh sliding knockdown. Ah It's always right after that hit where I just I stopped functioning as a piccolo I should probably just fake fake a couple buttons and then go straight into a dragon rush at my skill level As a piccolo, which is very low Level three with Android 17, but what's the mix? Don't try anything fake. Don't All right special beam actually switch out switch out switch out. Oh, oh You do not want to be left in with that much blue health, and we are trying to preserve for sparking Oh, wow, we just got big drops. Oh Wow, this is awful. Oh, we catch up That was bad. Oh No uppercut comes out in time Yikes. Yikes. Yikes. This is definitely looking like a kill if he decides to go out into TN which he Does nice good choice At this point though, they're both looking pretty low So if we can get TN down to enough health then we don't we really don't have to worry about a sparking blast at all No, okay, no grab Okay, I'm glad I didn't reflect that Okay, we got him. All right.  We'll stall. Oh Wow, he could have he should have blocked that. All right If you spark if your opponent sparks you got to stall that out as much as you can All right. Nice the kick actually kills him. I was worried we wouldn't be able to finish him off But we take game one. It was a little it was a little too close for comfort But we did have a sparking on our side as soon as he popped it That was when you know, we were a little safer in our game plan But we're heading into game two and we're gonna need a little more than a spark. Oh Wow, that was a great opening barrier.  We get hit too early Real shame that piccolo's assist didn't do much for us there And we are just getting melted right now. So we are we're now taking all right and Good enough. Ah the overhead doesn't hit. Oh Respect my mix. Oh nice back dash. He gets out of there with just the smoothest. Ah And he catches our air-dash in I got a little too desperate there I think he saw me coming for that 17. Oh God, that was pure panic. Wow. Well, you're witnessing now is pure panic Let's calm it down. We got enough health to last us for a little while Hmm another level three with Android 17, but what's the mix? Oh God, it's just a shame to see it whenever it happens That was very lucky by me Okay, go right back out into 17 if we can behind the back, but just kidding. Oh, yes No, don't kill piccolo. Please. I know I got a little greedy, but if you could just drop this Okay, you didn't drop that. I was like, yes. I know I got too greedy. Let me go. Let me go. Let me live Please ah, I see you're not Amanda bargain. That's fine Or Amanda binds for that matter Where's that super dash? Give it to me. Fine. I'll if you're not gonna make a move then allow me.  Oh, wow, that was incorrect Incorrect motion there. Oh, wow. We are getting punished All right, we take out 17 nice and simple bad clash for 17 17 Usually doesn't want to trade normals with anybody so All right, we got we got we got big punishment big punishment bad answer In my hurry to get out. I do myself really no switch Okay, then this is definitely where we use our sparking here because both our characters are looking a little dead They're both looking a little too ill Okay, whoop, pop it. Okay. Oh No We just got beaten out by buttons from from he literally fell from the heavens clicking buttons And once he got to the ground his judgment was swift Just like this divine divine fury All right, is this the time is this the time where we trade in our card and become a scrub? Hello scrub life. It's me. Dato. I've been here all along.  This is That I'm I lost I lost this game After that, that's a big no you cannot lose a character that early in this situation Hmm, but hello That's not hitting that was bad Okay Yes, he respects the mix and that will be your downfall No, no big leg. Oh the the hair box The hair box did you see the delay on that hate? Oh, it does not matter cuz we got the hard knock then we got to keep the pressure up Oh my goodness But yeah, yeah hit a button Sometimes you hit a button when you shouldn't huh? Oh That connects. Okay, never mind. Haha. Sometimes you hit a button when you should it.  I probably shouldn't have even backed up for ghost okie there I probably should have just kept my finger on the trigger But you live in you You live in your lag, I guess you live in your lag.  All right, let's just go all the way over here I've not leveled up yet. So all right. Let's just see how much damage this does. Ah Yes, that is exactly what you want to see. All right, so we'll get 17 back out He's gonna be super low. You might even try a level one strategy. Nope. Oh, wow He takes the second hit to get out. All right, cheese it. No bad choice. He was waiting for the cheese To be fair, I probably shouldn't have done that piccolo is more than capable of opening people up without that Double three hard knockdown. We don't want to waste sparking. Oh Beautiful whiffs the medium at just the right angle and I was too slow on the trigger. Eh, we're dead. Goodbye world Damn now this game's close Use the second bar to get Goku blackout and secure an Android 17 assist not too scary The 17 assist isn't the the worst thing in the world, but you'd rather have you'd rather him have no assist.  I said we wouldn't have to worry about no The only reason that hit me too is cuz I just didn't do anything. I didn't even block. Oh, that's dead with TN This is where TN is deadly Boom just finishing us off with massive damage. I Want to say it's not over. I Want to say it's not over but to be honest Yeah, okay to be honest. This isn't the best situation We got a near full health goku black.  We got to finish him here Come on. Come on. Yeah, nice. I don't think a level one would have killed there. Maybe I'm wrong But this is definitely the safer option Take it while we can we're out of sparking. We're out of meter And this is a very eerily similar situation to last time, huh? Okay, but we've got to play through it Oh, goodbye world. Don't down having me. Oh Oh I'll tell you right now. This is not the situation. I saw myself in No, no, no, no, I should have key blasted or something You can't I got away with that a lot that match. So expecting you to get away with it there That was a little too much a little too much in my opinion What is it one two? I actually I should have been keeping track of that We'll say it's one two right now with my opponent 17 just bopped me Okay, let's try to stick this landing That was not the way I saw that going. No All right, we're back in control. I think we need to pick a little out in the driver seat instead of gohan Change of plans boys piccolo's fired Oh, he could he had an air dash after that. I didn't even realize Air dashes after the beam to continue pressure on piccolo Hmm. He's gonna hard knock down this here. No. Oh wait, he'll probably follow up with goky black Okay, wow, he's just going for damage The turnaround auto combo comes out before my light and piccolo died again No, that is not how I wanted to lose man Ah darn, I saw I saw him his back turned to me.  We go into the corner another hard knock down. Nope I don't like that that's it. I don't like that Okay, and we die here Wow, this one's impossible Remember how I was like, I don't know about the last one.   Let's go Come on I've never been mixed up that bad. I can't believe you reflected. That was like his first reflect all game, right? Was that or was the first match he reflected a bunch Okay, get let's get back 17 Okay, that was impunishable range. No, that was supposed to be the bay. Oh, we're dead, dude We can't heal through this. Oh No, we oh He healed my boy. He'll heal heal heal. Take it. Take it. Take it. Take it. Oh Come on Come on. If we're not out of the fight, I don't want to hear nothing If go tanks are still breathing. We are still in this Huh?  Oh, we're not healing this We're not even healing this Well guys, we went ahead and took the win in that set that I wasn't supposed to record I turned off my mic. So I didn't the commentary was just awful. Uh, but at the end of the day Uh, my opponent took it one three I officially that was the best the first the three set I guess more of the story is just because you you had a lot of love for something once doesn't mean you should come back to it Especially when you don't play go tanks anymore. I I suck with go tanks and I just will never play them That's that's the only character in this game that I won't ever play You know, well that is like I'll play them for videos and stuff like that here and there But for the most part me and go tanks, we don't get along other than that If you have a favorite moment, let me know down below in the comments from this video If you're a go takes player and you're down there just type I am go tanks player period with no other No other context at all and also make sure to leave a like and subscribe to the channel If you're looking forward to season two content coverage on this channel It'll be all over the place. We'll be covering it day in day out week of with whoever the dlc characters are And and many more games as well as commentary and analysis on the finals and all that It's it's gonna be a great time Coming up here in a few days But yeah, guys I have a few videos on your screen right now that if you want some more fighters content You haven't seen them make sure to go give make sure to go give those a watch That will probably help you out with that itch. I'm dr. Doya. Hope you enjoyed the video. I'll see you in the next one


My name is Chi Ting Chan, I'm from Hong Kong and I do research on the theory of wave equations and material science and one of the topics that I have been working on in the past couple of years is about invisibility clocks. A so-called clock works by guiding a wave away from an object and if you ask me you say that you know who cares why why should I have such a technology and one application that I can think about is for example you want to exclude a wave from a certain area, certain domain to protect yourself say for example an earthquake is coming now earthquake is in fact the kind of wave a vibration of the earth crust and you say that okay I do not want the earthquake to affect my community and then in principle I would say in principle in practice it's not easy but in principle you can design a clock around the city so as to guide the earthquake wave away from the community to somewhere else in which the damage is less. It is about designing materials that can do wonders and it turns out that for most of the time the materials take for example the invisibility clock the material needed cannot be found in nature and then we have to design them we have to make them and these type of knowledge in the long run can help industry to design new materials that can go beyond go beyond what the material in nature can do for us.
