He was 54 years old. David leaves behind his elderly parents, his young children, a son and two daughters, his elder brother and many relatives and friends who loved him so very much.

On behalf of his family I would also like to take this opportunity to express my sincere gratitude to all who supported and helped David during his last days in life. Many thanks to his students, especially thanks to Li Songting, Dai Wei, Xu Zhiqing, Zhang Yaoyu and Xiao Yanyang for their meticulous care and companionship.

We set up this memorial website for family and friends to share memories of David.

"Dear David
   Jack informed me that you are gone to HEAVEN.  I missed you since I believed in that you could recover from the disease.   Now I am reminding happy good days with you in Los Alamos, Shanghai and Tokyo.  
    At Los Alamos, you were communicating frequently with me about mathematical physics, statistical physics and nonlinear wave phenomena during my stay there.  We also exchanged the philosophical thinking on Chinese culture and Japanese one there.  
    At Shanghai, I observed that you were conducting many research projects, teaching many excellent students and inspiring young researchers.  Also, you treated me many times in excellent Chinese restaurants.  Conversations with you and your excellent young researchers were one of my treasures in my life.
    At the Institute of Statistical Mathematics, Tokyo, you kindly gave an excellent invited talk on ``multi-scale modeling of the primary visual cortex’’ in our meeting on biomedical engineering.  Your talk was quite impressed for all of us.  Also you kindly encouraged our PhD students during the stay in Tokyo.  Reminding is also the cheerful time of visiting Sushi-Bar with me.
    Thank you very much David for everything done for me during in the past.  I am sure that you will be living in our minds with the persons who met you and communicate with you here.  I pray that you are with GOD in HEAVEN, and your wishes and dreams for your family members, your excellent students and all of your friends will be realized in the near future.

"David was an incredibly influential person during my time as an undergraduate and Ph.D. student at RPI. His insights in the fields of computational neuroscience and applied mathematics are beyond impressive and he has left an everlasting mark on the academic world. His advisory guidance through my Ph.D. was more than appreciated and respected. David’s influence extended much further than my academic life, his sincere care about our well-being as students and people was always apparent. I learned just as many life lessons as I did mathematical ones from David. He will be truly missed by all of those who knew him and had the honor of spending time with him."

"I didn’t know David or your family but wanted to share some words of encouragement.  From your comments I can see he accomplished many things in life.  Although death just seems to be a part of life it doesn’t make it any easier to see our loved ones pass away.  We can take comfort in knowing that it wasn’t God’s original purpose for people to die.  We can look forward to a time when John 5:28, 29 will be fulfilled and there will be a resurrection.  Until that time deep sympathy—-Julia"

"I had Professor Cai for my Networks and Dynamics class in Shanghai, China. He only taught for around four weeks of the course before the next circulation, but in that time you could tell he had a power and confidence about him. He would wear a chain and a tank top to class, a sight not much seen, but a sight that again let you know his life was one of a straightshooter - a mind deep in his work, relishing in the excitement of it. He always seemed young in spirit yet old in wisdom. He never harbored any animosity, nor do I know of any student that held any against him. Beyond his impressive research and intellectualism, his absolute line of sight is something he's left behind that we can all be inspired by in his name. And although I only knew him from the ever-present eye contact in the class where we talked of chaos and nonlinear dynamics, there was a fire passed on through that."

记得开学的时候,因为你刚搬到温州,第一天上学我和姐姐还绕道去你家带你去学校。现在想来,我还曾经给你这位大师当过‘引路人’ 呢。记得小时候经过你家门口时,常常听到你父亲和你一起讨论《参考消息》上的内容,小小年纪已经开始关心起国际大事,而当时我们这些同龄人还沉浸在小人书,连环画的世界里。

"Has anyone here seen my old friend David?
Can you tell me where he's gone?
You know, he freed a lot of people
but it seems the good die young
I just looked around and he was gone..."

"While at Los Alamos, David was first my collaborator, then also my postdoc, and always my inseparable friend, from whom I learnt invaluable scientific and personal traits that are still with me today. He had a remarkable presence of competency, perfection, and warmth in everything from science, to political and philosophical discussions, to food and art, and even to lifting weights, which was a significant part of our weekly routine. I am professionally proud to have been part of David's early career, and I am immensely grateful for his close friendship, which he readily extended to my family and our cat.  As our careers eventually took us in different geographic directions it was expected that we would naturally reconnect and reunite one day. The anticipation of that day always gave a bright outlook. The change in this outlook has left a deep void.
David, you will be sorely missed by many, including me."

"I never met with David or talked to him before.  In 2015, I submitted many applications to universities around the world for a faculty position.
One of them reached to David's desk. He carefully read it and decided not not give me a chance at his institute but he forwarded my materials to Prof. John Hopcroft, which helps me to open the door of SJTU.
When got the invitation letter from Jiao Tong University, I was really surprised. I can hardly image how many emails he could recive everyday. Even though he is very busy, he still carefully process every email for his university.

I knew he had been illed for quite a long time. But i was really shocked to know this sad news. It is a great loss for China academics."

"I got to know David at Los Alamos. Besides we were apprentice-fellows under Dr. Alan Bishop at T-11, his formal B.S. adviser at Peking Univ., Prof. Danhua Qin, is also the wife of my Ph.D. adviser, Prof. Zhao-bin Su at CAS. We were friends since.

David taught me many things, and we had lots of fun together. We shared many friends, and I had the chance to meet his parents. As my wife recalled my last Christmas at Los Alamos, we had a party at Dr. Zukun Chen's house. All the other parties at the table are still alive and well, only David parted forever!

The car he sold me was wrecked in a snow storm at Los Alamos, but I am still driving the way David taught me. The music clubs he had me joined were all out of business, but I am still listening to the same classical music he introduced me to. David might paint or draw no more, but the paintings he painted are still hanging somewhere in my house.

Some people live after their death because they are remembered.

We couldn't find a proper way to send our condolences to his grieving parents and family, and hope in this way David could be remembered as we shall always do."

"I LOVED working with David during his years at the Center for Nonlinear Studies at Los Alamos in the 1990s.

Ostensibly, David was the student and I was the mentor. I was indeed 15 years older but most of the time I felt he was 15 years my senior in mathematical dexterity and physical insights! Those years of partnership and productivity -- and friendship -- shine brightly in my memory. It has been a delight to follow his wonderful career since leaving Los Alamos.

David's life has been cut short cruelly but his impact will survive for many years to come in the lives of those he taught and helped. A life too short, but a life so well lived.

Peace to your family David and rest well.     Alan."

"初见David,是14年之前鄂维南在北大组织的第一期暑期班讲授统计力学的班上,穿着紧身背心,裸露性感肌肉,脖子还有粗粗的金项链,彻底颠覆我对大学教授的认知下限。然而,一旦接触,就知道蔡老师是那么温暖、平和、热心的人,毫无架子。后来蔡老师有段时间又在北大给本科生开常规课程和接触研究生,教授了很多北大应数出来的学生,其中不少后来一直受益蔡老师的指点。我在读博士期间,在北大访问时请教过David非线性动力学的基础知识,蔡老师事无巨细,很有耐心,当时给我了很大的信心。后来,常去Courant, 也常去交大,每次见到David跟他打招呼聊天,都是非常开心。David Cai温暖的人格魅力,耐心育人的品格,渊博而独特的知识视角,令每一个有过接触的人都难以忘怀。

"两个月前发邮件请蔡老师帮忙做为申请的reference, 他很快回复说愿意写。半个月前找他写推荐信时,他说很抱歉,由于身体疾病无法胜任。那时才知道蔡老师已经癌症晚期,以致到了临终关怀期。而两个月前他竟然在如此严重的病痛折磨下依然愿意帮忙。。。天妒英才,让这样一位伟大的老师早早离开了我们!祈祷蔡老师在天堂一切安好。"

This tribute was added by Wei Zhu on 23rd October 2017



David是我遇见过的最聪明的人中最用功的,没有之一。我在Courant期间,因为需要等待计算结果,常于夜里一两点回去,自以为勤奋已极,但电梯隔壁的办公室里David仍工作着,等我早上八点多来所里时,David居然还在!有时忍不住问David,为何如此用功,身体竟然又如此康健。David只回答了我的第二问:人体有很多状态,需要激活。彼时我正作Neuroscience数值试验,对neurons的firing rates引导系统的状态刚有些了解,觉得可能确实如此。


David又是乐于助人的人。08年我找工作,因第一次job talk作的不好,心情沮丧。David提出让我在他和Mike面前作下演讲,看如何改进。演讲过后,David对Mike说我可以拿个尚可学校的offer,这是对我的工作的最好的鼓励和肯定,令我感激不忘。

"I am deeply saddened by the news of David's pass away. It was exactly 20 years ago I got to know David when we both started to be postdocs at Courant Institute. I feel so lucky and honored that ever since David has been a great friend. On numerous occasions I have benefited so much from our conversations either on mathematics,  sciences in general, or in all aspects of life. David is not only a amazingly broad and deep scientist with great taste, but also a decent person. I admire David's great courage in his struggle against the illness in the past more than 3 years. I still vividly remember our last dinner together in April. It is so sad that David leaves us so early. He will be badly missed by many of us.

Best wishes to David family!

"David,  We were classmates in the High School at Wenzhou for two years.  At the High School, you were good at everything you studied.   After the High School,  we met three times.  The first time was at the home of our mutual friend (Yaobin Cao) at Wenzhou before both of us departed for USA in the summer of 1986.  Your character and originality were nicely reflected in your unique style of clothing that is still vivid in my brain.  I still had a fond memory of the occasion.  Our second meeting was at Los Alamos, New Mexico in 1994.  I was invited to give a talk on fiberoptic instrumentation at LANL.  We had a lunch together in a small café and discussed many items including politics.   I noticed that you had your independent opinion on political science too.  Our last meeting was at Wenzhou in 1999.  Both of us were attending the Oversea Chinese for Development of Wenzhou (“Dog and Pony Show” by the current standard).  We were so happy to take advantage of the opportunity to meet our high-school classmates.  Your talent and personality are contagious and have the lasting positive impact on people interacting with you.  You set a high caliber on how a good scientist should do.   You will be deeply missed!!!"

"堂弟比我小1岁,少年时的身影依稀可见,记得申瓯读初中光景来过蔡里老家一次,那时家里还是老宅,当中有大厅间,兄弟过招,申瓯力气很大,我打不过他。去美国以后,大概是90年代中,有回故乡一趟,我还忙着写标语表示欢迎,因不知道他的准确职称,到底写博士好还是写教授好呢?心里思量了一番,那天还有雨和风,我在他可能进村的路口都贴了标语。高中期间我给他写过信,他回信介绍武夷山风光,说是“碧水丹山”,我印象非常深刻。斯人已去,愿他在天堂里不要再那么忙碌,安息吧!                                           蔡启增"

"从未见面过的蔡申鸥兄弟,安息吧。昨天在网上看到“千人教授蔡申鸥过世”的消息,心头不由得一紧,像是失去了一个老熟人 一样。其实我与你不但从未蒙面,甚至都没有听说过你。首先从名字上,我知道你是青田温州一带人。因为我祖祖辈辈都是喝瓯江水长大的,又都姓蔡,  所以一下子就有了一种亲近感,也许我们祖上都是温州平阳人吧。第二我们都有相似的经历,学术上都稍有成就,工作上也很努力,很认真。虽然我没有去中国做千人教授,我在培养中国学生学者方面也花了不少时间精力。看了你的学生与同事们给你留的言,感慨 万分,看来我们都是以学术为乐趣的人,也都是愿意帮助年轻人的人。我好像觉得冥冥之中我们本来是可以交朋友的人。痛惜。
前些年一位年长我10几岁的学术上的朋友突然生癌症过世,当时听说了极其的震惊。这些年也感慨了不少同龄人的去世,但是今天我是第一次被一位完全陌生的人的去世震惊了。希望申鸥教授家人节哀。也希望我的朋友们,同龄人也都注意锻炼保养劳逸结合。   Weijun Cai, University of Delaware"

Even with all that he has done, David was a humble man who was always happy to be there for his friends and colleagues. To me, as to many, he was a generous mentor and close friend. It was abundantly clear by his warm smile just how much he cared for those around him. Not only did David teach us about science, he also imparted his philosophical insights, inspiring stories, witty humor, and warm human nature. In many ways, he certainly shaped my own mode of thought, scientific perspective, and life view. I fondly carry with me David’s love of life and knowledge, and will always hold him dear in my heart.

"Sadly INS lost one of its founders and our dearest friend, David. Each of our lives will be impacted by the passing away of a dedicated and talented scientist and a great person, who has devoted his last ten years of life to the welfare of INS and its students. I myself will forever miss his smiles and his gentleman mannerism during the time at INS. David showed us the courage of a man in the face of death and his extraordinary persistence in carrying out his mission to make an impact on the applied math research in China.

His absence now will remind us of his lasting contribution he made to INS, and we will surely have a special place in our heart for this special friend - David Cai."

"David, We first crossed paths while postdocs at NYU, and since then I've had the privilege not only of watching your scientific career blossom, but also to co-advise students with you and Gregor.  I witnessed how you shared with the students not only your wisdom and guidance, but natural warmth and encouragement.  In particular, you exhorted them to upraise their vision to the broader scientific questions, which were always prominent in our conversations.  I believe you extended to me a greater degree of most generous hospitality, both in New York City and Shanghai, then any other collaborator, and several of these shared experiences have been singularly memorable.  I believe the last time I was able to visit you, we gathered with Gregor and our students at a chinatown restaurant where we shared a "Happy Family" dish that was a particularly memorable delight.  In retrospect, it's an excellent symbol for how I remember the spirit of you and your research group -- a seamless blend of research, fellowship, and deep conversations on varied topics -- and I cherish the opportunity to have partaken in it via our collaborations.

"David was a dear friend, wonderful scientist, and veritable renaissance man.  He was kind to everybody, he was like a father to his students and postdocs, and generous to his collaborators. He had profound and brilliant ideas, which he did not mind explaining in simple and accessible terms.  His conversations were full of great knowledge, understanding, wisdom, humor, and compassion. He enjoyed life, and shared his joy with those around him.   David was many things to many people, but, most of all, he was a good man.  The world was better because of him. I am grateful to have known him and that he was my friend.  A cruel illness took him away much too soon.  I and many others will miss him sorely."

"刚获悉蔡老师病逝的噩耗,心情悲痛。 离开Courant已有八年了,但往事历历在目。与蔡老师做学问的三年(2006-2009)是我学术生涯最重要最有意义的阶段之一。

最初见到蔡老师, 是在2001年春季北大举办的一次计算与应用数学国际会议上,他头戴一顶鸭舌帽,穿着休闲,与其他数学家很不一样,留给我的印象极深。后来再次遇见他,是2002年秋季在IAS,鄂维南老师请他讲授“拿手菜”课程---统计力学。蔡老师满黑板地推导讲解之余,不时品一口他紫砂壶里的浓茶。2006年,我有幸加入了蔡老师的Group做博士后,从事计算神经学研究。这是一个崭新的不同于我博士研究的领域,蔡老师给予了我耐心的指导和极大的鼓励。一次次Group(包括Adi Rangan, 栋焯, 胡丹)长时间深入的讨论,克服困难时的激励,获得好结果时的喜悦仍记忆犹新!  最后我撰写论文时蔡老师反复好几遍地逐字逐句的修改稿仍保存在我的电脑里,提醒我现在写文章时不要再犯同样的错误。蔡老师对科学研究的热情和严谨永远值得我学习和尊敬!

蔡老师还是个科技达人和电脑高手。他最早使用Tablet(先是Toshiba,后来IBM X系列)写讲义。2007年我的IBM T30硬盘坏了,他还亲自为我换了块更大容量的。

蔡老师喜爱音乐与艺术。在他Courant办公室里,夜深人静时,他有时会把古典音乐放出声来与大家分享。百老汇的音乐剧他也都全部欣赏过。他的中国画水平颇高,有次聊到过:他在Los Alamos National Lab 工作期间,用国画描绘New Mexico的山景,但就是很难表现出咱中国山水画的意境。


蔡老师爱好锻炼,保持一副好身材。他也鼓励我要锻炼,充分利用NYU Gym的条件。但真没想到他却被病魔击倒了……

"大四快毕业的时候修了蔡老师的生物物理学,老师上课的时候温文尔雅,声音不是很大,但是娓娓道来。有时候兴之所至,就会提一些有意思的小问题,更像是研讨而不单纯是上课。他曾经自嘲说自己的字体比较不易辨认,但其实我们都觉得挺好看的。很久不接触生物物理这个领域,大部分知识早已模糊,和蔡老师印象最深的反而是之前他请我们09级的同学在留园吃饭聊天的情景。饭桌上我们几个懵懂无知的大小伙子面对蔡老师很是局促。近距离非课堂接触学术大师的时候, 有些不知道该说些什么。记得蔡老师在那时候就跟我们聊到了人工智能和机器学习,当时听来很是新奇。印象中饭桌上他并没有怎么聊他的科研内容,而是勉励我们要在学术上追寻自己的兴趣。这么多年过去了,很感激蔡老师的教诲。高山仰止,景行行止,蔡老师对我们致远学子的影响是潜移默化而又深远的。愿蔡老师一路走好。"

"David, we will sorely miss you. I will fondly remember your hospitality
and companionship in China, and exciting conversations about science."

This tribute was added by Mainak Patel on 22nd October 2017

"David was an exceptional teacher, scholar, and researcher with an unparalleled passion for science and the application of careful rational thought in all aspects of life.  More than that, he was a warm and nurturing mentor and a true and dear friend.  I was never able to express to him how profoundly he impacted my life during my PhD years by instilling in me the same passion for science and rational thought that he embodied, but I continually strive to live up to the ideals that he has passed onto me, and his memory will live on in his family, friends, and students.  I will miss his friendship, wisdom, and guidance deeply.

"听到这个消息之后,不觉间重温了遍这些年在致远的日子。跟蔡老师说实话没什么交集,除了他的大金链子和口头禅“Opps!”之外,还有两件小事让我印象最深…第一件,虽说大学学到的东西基本上忘光了,可唯独蔡老师的热力学统计里面的那一节Random walking的课,给了我一个很重要的灵感,就连昨天科研的时候还在用这个概念建模;第二件,就是很感动,毕业了几年之后,他居然还认识我这个学渣以及知道现在在哪里工作。衷心的钦佩他,作为一个老师,真正做到了关心他的每一个学生。挺后悔没有珍惜跟这么一位大牛一起共事机会。我坚信,人的离去有两次,第一次是仅仅是肉体上的离去。而第二次,当世界上再没有人知道这个人存在过,这才是真的告别了。虽然蔡老师肉体上离开了我们,但是那儒雅的气质,和对科研所做出的成就,会让后人永远铭记!RIP"

"Prof. Majda’s tribute to David

David Cai was a truly brilliant applied mathematician,a great friend and a wonderful scientific collaborator for me on wave turbulence and information theory.David had a very sophisticated scientific and cultural perspective on the world and he shared his ideas,insights and knowledge generously with his friends and students.
  David taught me many things about Chinese culture and history during my many visits to Shanghai.I am especially fond of trips with David together with my wife,Prof Gerta Keller to Shanxi province and the Yellow Mountains.David is Gerta's favorite among my math friends and we will always cherish his friendship
David dealt with his health crisis with great dignity and managed to meet with me in my Courant office every few weeks until his last two months.I am saddened by the passing of David Cai but comforted by the fact that he truly left the world a much better place.
                                 Andy Majda"

"虽然近日大家有一些思想准备,还是很难接受这个噩耗,悲痛难以入眠。 蔡老师,和他接触过的人都知道,他是一个特别纯粹的科学家,对科研的热爱感染着身边的每一个人。 他才华横溢,在生病的那段时间还经常在微信上和同事们讨论一些有趣的学术或者艺术问题。 他经常和我们说的是不要为了发表论文去做没意义的工作,一定要不忘初心,坚持凭着自己的兴趣选择有深度的科学问题。

昨天清晨看到的第一个邮件, 便是噩耗!  没有多想, 立即买了机票当天赶到你家 送你最后一程。

晚上回到宾馆, 难以入眠。 耳边不时回荡着我们都喜欢的普契尼的歌曲“Nessun dorma”--今夜无人能眠。

和你成为终身的朋友, 始于我们还都是博士生的时候,在New Mexico 山里的Los Alamos National Lab.  也许是因为我们都在北大度过了几年改革开放后最激荡的岁月--那些年被认为是北大这几十年来“最北大”的岁月--的原因, 让我们有了许多共同的语言, 从文学, 西方古典音乐, 到时事,到科学。。。  也因此成就了我们今后在交大共同创业的缘分。

在交大这几年, 是我们人生中浓重的一笔。 想起当初我们一起在交大创业的经历, 和这些年共同走过的路程, 我想说的是,what an amazing ride we had!

天妒英才, 让你走到这么早!  You are so courageous in fighting such a long, and difficult battle!  You lost the battle, but you have won the hearts of many who know you and adore you.

人们常说, 人生最重要的不是生命的长度, 而是厚度。 This is for you.
You have lived, and accomplished, what most others cannot in their much longer lives. 你的学生因为你而改变了他们的人生, 对你的朋友而言, you enriched their lives.

送别你后走在秋天的路上, 落叶缤纷。 你在秋天离去,  让我想起泰戈尔的诗:
“生如夏花之灿烂, 死如秋叶之静美”。

I will always miss your friendship, miss many memorable moments we shared together.

"Dear David,

I will forever miss you - you are irreplaceable.

I have never met another scientist who combined so well scientific excellence, wide intellectual interests beyond your own field, fantastic humor and - most of all - the human warmth emanating from every word you said or action you took.

You are truly missed - but your vision and warmth persist forever in the institute you created.

I am deeply sad I can no longer talk to you - but deeply happy to have known you, and learned so much from you

With endless love,

"David Cai was an outstanding applied mathematician and scientist; but much more than that, he was an outstanding person, an exceptional person.  The remarkable breadth of his interests went far beyond science -- to art. literature, philosophy, politics, society,...
It was an honor to know him, and an even greater honor that he was my friend.  David, I'll miss you deeply. With love."

"You perfectly exemplified the core of your philosophy, love.
Your life is full of love for science, for art and humanity, while your love is filling everyone around you and changes our lives in all the good ways.
But culturally introverted as I am, I felt too awkward to respond with "love you, too" properly when you were still around.
Now I can only cry it into the thin air, though I know it'd more of a relief for me than for you, but please know that I love you, too."
