2019年2月中旬，我到達(dá)了中國(guó)科技大學(xué)西校區(qū)，開啟了長(zhǎng)達(dá)數(shù)月的中國(guó)之旅。那是一個(gè)滿天星斗的靜謐夜晚，樹木、街道和公寓附近的小湖交織成一幅恬靜宜人的畫卷。在接下來(lái)的日子里，靠近公寓的小湖承載了我許多靜謐的閑暇時(shí)光。

一杯咖啡開啟了一次全新冒險(xiǎn)

因?yàn)樵跉W洲核子研究中心（CERN）工作過(guò)很長(zhǎng)一段時(shí)間，我對(duì)來(lái)自中科大的粒子物理小組成員非常熟悉，他們是一群杰出可靠又熱誠(chéng)的同事。2018年夏天，在歐洲核子研究中心的餐廳里，與趙政國(guó)教授一杯午后咖啡開啟了我的一次全新冒險(xiǎn)——離開這個(gè)我潛心鉆研數(shù)年的地方，前往世界另一端的中國(guó)。去中科大開設(shè)粒子物理課程這一想法在我腦海中一閃而過(guò)，但從這個(gè)想法出現(xiàn)的那一刻起，我就意識(shí)到我不能錯(cuò)過(guò)這個(gè)機(jī)會(huì)。

在抵達(dá)合肥的那天晚上，我一出機(jī)場(chǎng)，就看到司機(jī)和翔宇在等待我。翔宇是一名博士研究生，同時(shí)也照顧我在中科大的日常生活。盡管經(jīng)歷了一天的飛行已讓我疲憊不堪，但對(duì)這方新天地的探索之欲又讓我振奮起來(lái)。他們帶我來(lái)到了位于校園北側(cè)的公寓，當(dāng)我打開房門，迎面而來(lái)便是家的歸屬感：一間精致的大房子，其中家具設(shè)施一應(yīng)俱全，暖氣設(shè)備也讓我感到一股冬日里的暖意；往里走去，我站在陽(yáng)臺(tái)上向遠(yuǎn)方眺望，見識(shí)到了合肥的景色——樓下的樹木、花園、小湖和校外鱗次櫛比的高樓。

頗具歸屬感和現(xiàn)代感的中科大校園

我和另一位中科大教授彭海平共同任教的《對(duì)撞物理》，是一門粒子物理學(xué)的導(dǎo)論，其主要研究加速器上的測(cè)量/物理。我承擔(dān)春季學(xué)期的前三個(gè)月課程，每周為我的25名學(xué)生開展兩次講座。周一的講座較長(zhǎng)，為2個(gè)小時(shí)15分鐘；而周五的講座較短，僅有1個(gè)半小時(shí)。這也是我在中科大的主要教學(xué)任務(wù)之一。我會(huì)利用周一到周五的閑暇片刻跟進(jìn)研究，但為了充分準(zhǔn)備周一的講座，再花費(fèi)一部分周末時(shí)間用以備課。講座報(bào)告廳位于東校區(qū)第五教學(xué)樓的五樓，這棟頗具現(xiàn)代感的教學(xué)樓滿是求學(xué)的學(xué)子和窗明幾凈的教室。報(bào)告廳內(nèi)，教學(xué)設(shè)備也讓我無(wú)可挑剔，巨大的銀幕和聲效極佳的大廳，讓我可以無(wú)須聲嘶力竭地講課了。

The night I arrived at the USTC’s west campus was mid-February 2019,with a starry sky and a mild temperature.It was dark,and everything was a sleeping beauty around me,trees,streets,and the lake near the apartment that would have been my temporary home for a few months.The lake was close to home,and it quickly became one of the places where I spent many of the quiet moments on campus.

A coffee time marked the beginning of a new adventure

I’d known the group of physicists at USTC who worked on the ATLAS experiment at CERN,European Centre for Nuclear Research,for quite some time.They are fantastic,dependable and dedicated coworkers.In the summer of 2018,a coffee time at the canteen of CERN with Professor Zhengguo Zhao marked the beginning of a new adventure in China,almost opposite to the one where I had spent most of my professional life,Europe,CERN.The idea for the particle physics course at USTC flashed through my mind.But I was confident I could not miss it since the idea came out the flrst moment.

The night I arrived at the airport of Hefei,there was a car waiting for me,and the driver was accompanied by Xiangyu,one of the Ph.D.students who would have been one of the major supporters of my life at USTC.I was exhausted after a nearly one-day flight,but my curiosity about this new world overweighted my exhaustion.They drove me home,and when we arrived on the seventh floor of the building,and I opened the door,I immediately felt at ease.A lovely home,spacious,well-decorated,and well-equipped.With the heating equipment,I felt warm in the cold winter.From the height of my apartment,a small balcony provided me with my flrst view of Hefei.I was on the north side of the campus and below me were trees,gardens,small lakes,and tall buildings on the outskirts of campus.

The USTC campus with a sense of belonging and modernity

I taught “Collider Physics” course,which was essentially an “Introduction to Particle Physics”,focusing on measurements/physics at that type of accelerator.I co-taught the course with Haiping Peng,another professor at USTC,and my part lasted for three months,from just after the end of the year holidays to the end of May.I had a class of about 25 students and two lectures per week,one on Monday for about two hours and a quarter,and another on Friday for about one hour and a half.One of my main responsibilities at USTC was preparing the lectures.Having a long lecture on Monday and a shorter one on Friday allowed me to keep up with my research activity during the week but forced me to spend some of the weekends flnalising the slides.The Lecture Hall was located on the fifth floor of “The Fifth Teaching Building”,a modern structure fllled with lecture halls and of students.The equipment for projecting slides was flawless.There was never a problem,a large screen,the acoustics of the hall were excellent,and I could speak without shouting during my lectures.

安東尼奧·巴洛切利（Antonio Baroncelli，意大利），中國(guó)科學(xué)技術(shù)大學(xué)國(guó)際訪問(wèn)教授、Analysis期刊編輯。1972年畢業(yè)于羅馬大學(xué)，研究領(lǐng)域?yàn)榱Ｗ游锢砼c核物理，曾擔(dān)任歐洲核子研究中心研究主任。2019年開始在中國(guó)科學(xué)技術(shù)大學(xué)近代物理系超環(huán)面大型強(qiáng)子對(duì)撞機(jī)裝置（ATLAS）課題組開展教學(xué)科研工作。Antonio Baroncelli (Italian).He is an international visiting professor at University of Science and Technology of China (USTC) and the editor of Analysis.He graduated from Sapienza University of Rome in 1972 and his research interests include particle and nuclear physics.He was previously the Director of the European Centre for Nuclear Research and since 2019 he worked in the A Toroidal LHC Apparatus (ATLAS) research group of USTC’s Department of Modern Physics,where he taught and conducted scientiflc research.

中科大的校園環(huán)境也相當(dāng)不錯(cuò)：幾處花園、人工湖和人頭攢動(dòng)的大道錯(cuò)落點(diǎn)綴其中；年輕的學(xué)子、穿行其中的自行車和電瓶車也為校園添了幾分生氣。由于校園完全對(duì)外開放，當(dāng)?shù)鼐用褚步?jīng)常漫步于花園和小公園之中，享受著恬靜祥和的時(shí)光。

校內(nèi)只有零星幾家商鋪：幾家果蔬店、一家小型超市、一家理發(fā)店、一家洗衣店，僅此而已。這里的三兩家水果店倒是讓我頗感興趣：店里售賣去皮后分裝的當(dāng)季水果。有許多人買來(lái)削好皮的棍狀水果（甘蔗），邊走邊嚼。

校園里還有幾個(gè)食堂，我去得最多的就是教職工食堂，在那里擺有一條長(zhǎng)長(zhǎng)的自助餐桌，上面有各式各樣的菜肴可供選擇，蔬菜、肉、魚和各種湯、中式點(diǎn)心。類似自助餐，只需要在入口處付款即可，價(jià)格也非常親民。教職工食堂里有兩個(gè)很大的教職工專用區(qū)域，為了享受到陽(yáng)光，我總?cè)ツ莻€(gè)有著落地大窗的區(qū)域就餐。

The USTC campus was a wonderful place to be.Gardens,small artiflcial lakes,and avenues were lined with young students,numerous bicycles,and numerous electric motorbikes.The campus was completely open,and often,citizens of Hefei pass by the gardens and small parks to spend some time in a peaceful situation.

A few shops-fruit and vegetable stores,a mini supermarket,a barbershop,and a laundry-can also be found there,frequented mainly by students and faculty.I discovered two or three fruit shops that were very interesting.The peeled season fruit is sold there.Many people buy peeled and cut sugarcane,walking around and enjoying the refreshing fruit.

The campus has several canteens.A canteen reserved for faculties was the one I used to go to.There is a long table with an impressive selection of vegetables,meat,and flsh,as well as a large offer of soups and Chinese cakes.The system works like a buffet mechanism.You can pay in a minimal sum at the door,and can take whatever you want,and as many times as you want.In the canteen,there were two large halls reserved for faculty.I always used the one with larger windows and more light.

而學(xué)生們一般都前往其他食堂用餐，那里的點(diǎn)餐方式略有不同——售賣窗口多得讓人眼花繚亂，烹飪著各種各樣的美食。但是，在其他食堂用餐讓我頭痛的是，在點(diǎn)餐前要想好吃些什么，并且要用中文告訴食堂工作人員。我曾和學(xué)生們一同用餐過(guò)幾次，在得到他們的建議和幫助后，我便能享用佳肴。我大多數(shù)時(shí)候還是會(huì)去教職工食堂，在那里我經(jīng)常會(huì)遇到近代物理系的同事們。除此之外，有時(shí)走在校園內(nèi)，我也會(huì)偶遇幾位外籍老師。

別具一格的咖啡館和大禮堂

在我看來(lái)，校園里還有兩處別具一格的地方——USTC1958咖啡館和東區(qū)大禮堂。

這家咖啡館雖然才開業(yè)不久，但很快就成了一個(gè)地標(biāo)性的聚會(huì)勝地，在那里你可以品嘗到品質(zhì)不錯(cuò)的咖啡和各種精致的西式糕點(diǎn)。天氣不錯(cuò)時(shí)，咖啡廳外會(huì)擺放數(shù)張桌子，旁邊便是一個(gè)漂亮的小花園，高聳的樹木下人群絡(luò)繹不絕，或喝一杯咖啡，或肆意暢談，抑或靜心工作。包括我在內(nèi)的幾位同事，都會(huì)在這里點(diǎn)上一杯咖啡，一邊品嘗一邊查閱郵件，開啟新的一天。

另一個(gè)重要的地方是東區(qū)大禮堂。這是一個(gè)充滿著現(xiàn)代感的宏偉建筑，位于校園中央大廣場(chǎng)的東側(cè)，距離近代物理系大樓約100米。每隔一周，中科大都會(huì)在此舉辦活動(dòng)。在中科大任教期間，我也參加了一些活動(dòng)，如舞蹈、唱歌，還有管弦樂(lè)表演。雖然其中一些表演是源于西方或受到了西方文化的啟發(fā)，但有趣的是，它們都吸收了一些中國(guó)的傳統(tǒng)文化，尤其是在音樂(lè)方面。禮堂大廳能容納很多觀眾，聲效也很不錯(cuò)。每每開展活動(dòng)，總是座無(wú)虛席，其中不少是學(xué)生，但更多的是本地市民。我記得很清楚，我周圍的座席從未空置過(guò)。

中國(guó)給我留下深刻印象的事情太多，無(wú)法一一訴說(shuō)。最讓我感慨的是，我見識(shí)到這樣一個(gè)由一群同心協(xié)力的人所共同構(gòu)筑的社會(huì)——無(wú)論性別和崗位，普通人或?qū)W者，技術(shù)人員或警察，每個(gè)人都竭盡所能地貢獻(xiàn)出自己的一份力量，用個(gè)人之小我見證社會(huì)之大我，這無(wú)疑是這個(gè)蒸蒸日上的社會(huì)的最好體現(xiàn)。

There are also other canteens on campus generally and they are more used by students.There the system is different,and there are many cooking points serving specialized food.The problem was that there you had to know what you wanted ahead of time.In addition,you must also be able to say it in Chinese.A few times I went with students,and I enjoyed delicious food with their advice and help.But,to be honest,I went to the faculty canteen at the majority of the time.There I frequently met colleagues from the Department of Modern Physics and several times also some other western colleagues whom I met on the streets of the campus.

Distinguished coffee shop and assembly hall

Another thing that distinguishes the campus is the coffee shop,USTC1958,and the eastern assembly hall.

Opened not long ago,the coffee shop has quickly become an iconic meeting place.There you can enjoy a good cup of coffee and a good selection of western cakes.When the weather is flne,the clerk will put tables and chairs outside the coffee shop.Next to the coffee shop,it is a very nice garden.And under the trees,it is always full of people having drinks,talking in a relaxed environment and a lot of people staying there to work.Several coworkers used to start the day in front of a cup of coffee,including myself,and take some time to check E-mail.

The assembly hall is another important and magniflcent structure.Every second week,USTC organizes events in the beautiful large modern hall located on the east of a large square in the center of campus,about 100 meters from the building of Department of Modern Physics.While at USTC,I have attended a few events,including dance and singing performances and orchestra concerts.Some of these performances were western or inspired by western culture.But it was the traditional Chinese cultural spectacles,mostly music,that piqued my interest.The very large hall with a very good acoustic was always full of people.Some of these people are students,and the vast majority are Hefei citizens.What impressed me was that the seats around me had never been vacant.

Numerous things impressed me in China,and I am still working on elaborating on them.But what surprised me the most in China was the discovery of a community built by one united people.Many women and men,the simple and the professor,the technician and the policeman,all contribute with what they have to offer.They all have one goal in common and they are all working on a new social project,which vividly interprets the positive and progressive spirit.
