 Okay. I want to tell you that this is an art school, so the other, with the total art school, and for half an hour, and this is more complicated, you know? Wow. We are also online, so virtually we are like 100 in person. We are 20. And this is the good of the pro of the Unabrid conference. But in any case, we are super happy because we had the last school here in this room two years ago. So just a few weeks before everything was shut down. And we were, I don't know, 100. We have a group outside. It's huge. And it's super essential to start again. Because actually the in-person school has some benefits that are no way to get when you are hybrid, questions, interaction, and this is something that cannot be done throughout these schools. And this is really a loss for us that wants to visit kind of education. So anyway, so we are back. The Yambo School is organized in terms of lectures in the morning and end on in the afternoon. And then we have plenty of time for discussions because actually we are living together in the same place. We go for lunch and dinner all together. I think there is nothing more to say. There are lots of logistics stuff. So the key for the connection to the, to the, for the end zone, but this will, I think we will sort it out while, while moving along the program. And the first will be Nicola, that is the host, the local host, that is the person at CDP to help us inorganize this conference. And then we will start with the program slowly. I mean, in a couple of days we have to reach, you know, be it as a peer and diagrams and blah, blah, blah. So we have to increase the speed slowly. Okay. So I leave the voice to Nicola. Okay. So thank you. I think I have my microphone. Thank you. I'm Nicola Seriani. I'm the local organizer. Welcome, first of all, physically or virtually to ICTP. So, and to the school. Yes. So in principle, we, the speaker can, I'm so used to use it even during lectures that I don't mind, but anyway, let's, let's agree that the speaker can take the mask away. So, so I will spend a few words about what ICTP is. So you know where you are and, and some practical information on, how, how to move in these days. So what is ICTP? So we are, well, actually the building cannot be seen here, but anyway, this is a picture of the campus and on the Miramara Castle and the park. So it's, it's an institute that was founded in 1964 by Nobel Prize winner Abdul Salam and has basically two tasks. One is to do research in theoretical physics and mathematics at world class level. And the other one is to build scientific capacity in the developing world. So normally we would have the room filled from people from all over the world. Now it's, this happens only virtually for, for now, but we hope that things will change soon. And, and from the, from the governance point of view, it's an institute that was established with a tripartite agreement between Italy, UNESCO, and the International Atomic Energy Agency. So we are an institute which is part of UNESCO, the United Nations system. So we are the place where everybody talks to everybody. So to say, and I hope it will be like this in this time as well. So, and as I said, we have activity in research, in education and in outreach. And we have research activities in different fields of theoretical physics and mathematics from high energy, which is our starting point, condensed matter where I am and where this school is somehow situated. And the more recent activities in quantitative life sciences, for example, and many others, including high performance scientific computing. Well, this is a recap of our connection with the Nobel Prize winners, including, well, our founder won the Nobel Prize for, for the Electoral Week, Theory of Electoral Week Forces. Then, Filippo Giorgis, who's the head of the, of the Earth System section, is part of the IPCC, the International Panel for Climate Change, which won the Nobel Prize for Peace in 2007. And many of our scientists are involved in, in very close to collaborations so they participate in collaborations won Nobel Prizes more recently. One of our main programs is the postgraduate diploma program, which is aimed at pre-PhD students from developing countries. And the aim is to bring them to a level where they can join a PhD programs anywhere in the world. So it's, it's, we, we catch students in a very, in a crucial moment of their career and we open them, we train them and we open new opportunities for them. So this was, this is what we consider our, our most successful program so far. But we have, okay, first a lot of visitors from all over the world. These are bit the numbers from visitors since 1970. And above all, we have a series of, of programs that accompany scientists who have developed their world all over their careers from the, from, from pre-PhD level. So diploma, the diploma is here on the left, joint master's degrees, joint PhD degrees, but we also have programs to support scientists that are already professors, maybe in their, in their home countries, but don't have access to, to the possibilities to do research at high level because they don't have the, the contact or the infrastructure to do research. And we support them in order to help fight the, the, the brain drain from developing countries and including also conference and workshop, as you see here, which, and this is one of them. So, so this is all about ICTP. I think I have a couple of more minutes that I will use actually to give you some more practical information, especially for the people that are physically here at ICTP. So the lunch will take place at the Leonardo building, which is the main building a bit up the road. And I suggest that, so it's, it's a 10 minutes walk. There is a short track and the longer, but much nicer track through the park. So I suggest that today we go together through the park. It will take 15 minutes at most. Tomorrow we have a much shorter lunch break. It's only one hour because of the poster session. So tomorrow we will have some shuttle buses to bring faster. Some of you, because I think we're not going to be able to bring everybody, but the others can take the 10 minutes route on foot and I will be on that route. So, but I think we will see exactly what the need is in case we can, we can arrange. What else? We will have a conference dinner on Wednesday evening, but we will give more details when the time comes. Tonight we have a welcome reception which will be again in the Leonardo building at 7.30 on the terrace. So we will go back after the end of the lectures today. We'll go back again there. And I think that's all. A lot of information was given to you upon arrival, I think, you know, from the, from the info desk. At the, at the, here at the entrance and if there are any other questions, just approach me or the other organizer or the conference secretary. So I think that's all on my side. Other questions? If not, I give back the, the, the voice to the, to the next speaker to start really the school. So welcome again. And that's all. So is it you? Yes. Okay. So I think the best is that you take
