July 24-29 bet365 code year，The 17th International Logic、Conference on Methodology and Philosophy of Science and Technology (CLMPST) was held in Buenos Aires, the capital of Argentina。Due to the long voyage，A round trip (plus transfer time) takes 5-6 days，And there is an 11-hour time difference from Beijing time，Almost day and night reversed。I depart on July 20th，I just returned to Beijing on the morning of August 2nd。bet365 code is a rich and interesting experience，It’s worth describing。

Let’s talk about the city of Buenos Aires first。Maybe it’s because the city is located on the south bank of the Rio de la Plata，After leaving the customs and taking a taxi to the hotel I booked，You can feel the moisture outside、Cool and fresh air，It is said that bet365 code is also the origin of the city’s name (Buenos Aires，Spanish for "good air" or "fair wind")。Afterwards，Take a city bus tour of the city，You can feel a European style。The city has the reputation of Paris in South America: urban buildings mainly made of stone，These buildings are relatively old，Most floors are below 10 floors，Groups of tall people、Large、Not many new buildings。The city has wide main urban roads，Especially Qijiu Avenue, which runs across the entire city from north to south，About 140 meters wide，It is said to be the widest road in the world；There are large urban parks and green spaces everywhere，For people’s leisure、Recreation and physical exercise；Of course there are many scenic spots，Like the obelisk I visited in my spare time、Capitol Building、Congress Square、Palazzo Rosa (Argentine Presidential Palace)、Plaza de Mayo、St. Martin's Cathedral、St. Martin's Square、Cologne Theater、National Gallery of Art、Latin American Art Museum, etc.，Most of them are not far apart。The Athenian Bookstore, the largest bookstore in the city，Located right next to the hotel where I stayed，Reconstructed from the original theater，Four floors above and below，has become a famous tourist attraction。I walked around alone first，Later, I went shopping with several Chinese colleagues who attended the meeting。The vast majority of people you see on the street are white，bet365 code is because Argentina was once a Spanish colony，Most of the current residents are descendants of Europeans, especially Spanish or Italians，The original local Indians are rare in the city，bet365 code also illustrates the cruelty and bloodshed of colonial history。So，The main style of the city’s culture is European，For example, I visited the National Museum of Art of Argentina，its exhibits are in London、The same type seen in Paris and even countries such as Russia。On the contrary, when visiting the Latin American Art Museum not far from the National Museum of Art of Argentina，You can feel a new style: exaggeration、Abstract、Deformation and other indigenous or modern art elements。From these two art museums，There are very few works that describe Argentinian history (with a sense of resistance and accusation) from a local indigenous perspective，Most of them come from the perspective of Europeans who colonized here。

Let’s talk about Argentina’s economic situation as felt from Buenos Aires。When leaving customs，Because I have to take a taxi，So I exchanged 200 US dollars for Argentine pesos (the official currency of Argentina)，According to the official exchange rate of the day, 1 U.S. dollar is exchanged for 268 Argentine pesos。I found out later，The prevailing exchange rate in the Argentine private market at that time was 1 U.S. dollar for 500 Argentine pesos，You can even pay the taxi fare directly in US dollars at bet365 code exchange rate、Meal expenses and purchases at the market, etc.，The other party may even like bet365 code more。There are many people on the street shouting to exchange money，1 US dollar to 500 Argentine pesos。The small hotel I stayed in was less than three stars，Charge for converting Argentine pesos into U.S. dollars according to the official exchange rate，7 per day，bet365 code is equivalent to nearly double the price paid by locals。The official exchange rate is nearly twice as high as the private exchange rate，It shows that Argentina’s economy has serious problems。On a quiet street，You can see many homeless people，Living under the eaves of certain buildings，There are also many beggars。Once，I had lunch at an outdoor restaurant on the street，Ordered Argentinian steak and accompanying French fries、Bread, etc.，Also ordered a glass of beer。When not finished eating，A man who looked like a migrant worker passing by said to me，Can you give him the leftover food？I nod in agreement。A young Chinese colleague who was also attending the meeting was even robbed not far from the venue，But he is brave enough，Took the robbed bag back again。There are many shopping streets similar to flea markets in the city，Set up a stall on a very long street，I also bought a small Argentinian-style gift for my granddaughter at a market like bet365 code。On the streets of the city，There are many cafes and restaurants，And most of them are overcrowded。Perhaps bet365 code is because the residents of bet365 code city are more European，Don’t save much，Drinking coffee outside、Dining、Conversing with others is an important part of daily life。

Let’s talk about the 17th CLMPST conference。CLMPST is a logic discipline affiliated to the International Union for the History and Philosophy of Science and Technology (IUHPST)、Sponsored by Methodology and Philosophy of Science and Technology Branch (DLMPST)，Every four years。bet365 code time it will be held in Argentina，The conference theme is “Science and Value in an Uncertain World”，The meeting will be held in a teaching building at the University of Buenos Aires。It is said that more than 600 people from all over the world attended the conference，Chinese scholars participating in the meeting are: Chen Bo of Wuhan University，Liu Fenrong of Tsinghua University、Du Shaokai、Dong Huanfang (the latter two are doctoral students)，Zhang Liying, University of Chinese Academy of Sciences，Zhang Guihong, University of Science and Technology of China, etc.，Some Chinese scholars’ papers were accepted but their visas were not issued in time and they were unable to attend the conference。The conference actually has two agendas: one is academic exchanges among participants，The second is the DLMPST Congress。In academic exchange，In addition to participating in conference reports and their own speeches (the title of my speech is "Logical Exceptionalism and Its Dilemma")，You can also freely choose which thematic forum or group meeting to attend，And which person to listen to the report，Of course, some participants sometimes leave the venue to visit, etc.。The DLMPST Congress will only be attended by representatives of countries and academic organizations who are members of DLMPST。At bet365 code meeting，Valentin Goranko, a professor at Stockholm University in Sweden, was elected as the new chairman of the DLMPST Council，He is a logician，Have been invited to give lectures and offer short courses in many universities in China。Final decision of the congress，The 18th CLMPST will be held by Kobe University, Japan in 2027。

Finally, let’s talk about how Argentina will hold the meeting。The general characteristic is: let academic matters belong entirely to academics，Keep things as simple as possible，And very frugal。At the opening ceremony，The chairman of the local organizing committee will speak first，Later, the Secretary General of the DLMPST Council made a speech，Video speech by Council President Nancy Cartwright，It’s over in an hour and a half。There were very few people participating in the closing ceremony，The format and procedures are similar to the opening ceremony。The conference organizer should not spend much，They only provide meeting space，And coffee breaks during daily meetings: coffee、Drinks、Fruits and snacks，Once in the morning and afternoon。Specially worth mentioning: the first day of the meeting，Each attendee must present his/her name badge，Receive a slightly more refined paper cup，You can only drink coffee with bet365 code cup。I thought I received one every day，Leave it in the hotel the next day，Didn’t bring it，You can’t drink coffee that day，There are no new cups available。On the third day I washed the old cup and brought it back，Chat with someone over coffee，Put it somewhere，Forgot to take it，I won’t be able to drink coffee in the next few days，I can’t even find a cup to drink water。I was really thirsty once，Looking for a cup to drink from everywhere，Not found，Finally, a local attendee offered me a drink from his cup。Next few days，I will bring a bottle of mineral water to the meeting。Nearly nine o’clock that night when the meeting ended，I am still with Zhang Liying，Buy your own tickets to the Colon Theater，Let’s start with an Argentinian-style steak dinner，Enjoy the South American-style tango dance，It didn’t end until after 11 p.m.。
