I had the privilege and absolute honor to be a student of Dr.Coward in one lecture when my professor was not able to attend and found us this great gentlemen, educator, and mathematician for giving the lecture in 2019 Fall. The passion Dr.Coward gave in the lecture was absolutely marvelous. I remember that he gave some coffee chocolate to students because he saw a girl was very sleepy; he concluded that it must have been she was tried on the day and since the lecture took place at the end of day, he warmly made some comments that showed how much he cared about his one-time students.
One of his emails sent to his students had gone viral on the internet. Many arguments that he had made are very inspirational and helped me to understands some of confusion that I have had for a long time.

"If I’ve learned one thing about politics since I was your age, it is this: Politics, like most things in life worth thinking about, including mathematics, is very big, very complicated, and very interconnected. I’ve lived and worked in four countries on four continents, all with societies set up differently both politically and socially. I’ve discovered that there is no unique or obviously best way of setting up society. For every decision and judgement you reach, there are people who benefit and people who lose out. It’s the same with the way I teach my classes. I know that for every decision I make about how to teach you there are some of you who benefit and there are others who would do better if I did things differently. There is no way of getting around that. Every judgement you make in life is a question of balancing different interests and ideals. Reasonable good people can disagree on political questions like whether to strike or not, and they can disagree about far more contentious topics also.
All this may sound like speaking in platitudes. However it is a point worth making to all of you because you are so young. One of the nice things about being young is that your thinking can be very clear and your mind not so cluttered up with memories and experiences. This clarity can give you a lot of conviction, but it can also lead you astray because you might not yet appreciate just how complicated the world is. As you get older you tend to accumulate life experiences to learn from, and this is the source of wisdom, but the trouble is that the lessons we glean from life do not all point in the same direction. Sometimes it is hard to tease the correct learning from the experiences life throws at us.
So what are we to do with the fact that when we are young we lack a lot of the perspective we need to make definitive judgements about what is right, but that as we get older our judgements tend to be informed by our experiences, and these experiences guide us in contradictory ways, both between different people and within the same person?
I don’t know.
However one thing I do know is that you are not going to be able to avoid making these kinds of judgements, just as I cannot avoid making a judgment about whether to strike or not. Like it or not, I have to make a political choice, and I have to talk to you about it. For me, the choice not to strike is quite easy, but for you the kinds of judgements and choices you are going to face in your lives are going to be far from easy; they are going to be of a complexity and importance that will rival that faced by any previous generation. To an extent that you may not yet appreciate, the world is changing incredibly quickly. In just a decade, since I was your age, the internet and telecommunications has truly transformed the way we live, not just in rich countries but around the world. When I was an undergraduate, if I wanted to check my email I went to a little room in the basement to use a computer, and if I wanted to learn something I went to a library. The kinds of breakthroughs we are seeing in biotechnology remind me of the way people were talking about electricity in 1900. Of course I don’t know - nobody knows - but my guess is that biotechnology in the 21st century could be similarly transformative to the way the full power of electricity only hit prime-time in the 20th century. The recent controversy about the NSA has shown that the role of information technology on society can be, or at least might become, double edged. There is climate change, another controversial and difficult topic, the exact impact of which we do not yet know. These are just a few of the challenges we can see, and we should remember that history has a habit of throwing curve balls at each generation that nobody saw coming. And among all this tumult, our search for common human peace and happiness on some level becomes more difficult, though no less important. A previous generation dodged the bullet of nuclear armageddon when things looked bleak, but for your generation the bullets are coming thicker and faster than ever before. The potential all of you in your generation are going to have for both good and harm is tremendous.
I suspect many of you have heard sentiments along these lines before. However I also suspect that many of you will think something in response along the lines of `I know all that, but these things are for someone else to figure out, not me.’
That is a mistake.
One of the things you can lose track of when you attend a top tier university like Berkeley is just how exceptional and amazing you really are. I’m blown away every time I talk to you. The way you ask penetrating questions, the way you improved so much between midterm 1 and 2, the way you challenge me to be a better teacher, it just knocks my socks off. You really are amazing. I’ve taught students all over the world, and I’ve never seen a group of students so talented. I’m not just talking about some of you. I’m talking about all of you. It’s a privilege to be your professor. Sadly, however, I know many of you don’t feel that way. The difficulty you all face is that as you look around at all your fellow students, it’s easy to have your eye drawn by people doing better than you. Or rather, I should say people who look like they’re doing better than you. In reality the true extent of how much people are learning can be difficult to measure. Sometimes failures and adversity are better preparations for long term success than effortless progress.
Why am I telling you all this?
I’m telling you this because you all need to know that there is not some great pool of amazing people in some other place who are going to shape the way our species navigates the coming decades. The simple fact is that, like it or not, technology is going to change the way we live in the future, and you’re going to have to solve some very hard problems, as well as figure out how best to use new technology for good, while at the same time facing human dangers that have haunted humanity throughout history.
Part of the work of your generation is going to be technological, using scientific ideas to serve the interests of society, and part of the work is going to be fundamentally human, tied inexorably with qualities of the human condition - human emotion - that dominate the whole of history. These things are not separate, but are inexorably linked, and you are in a better place to understand that connection than me.
I can’t tell you what your particular role should be in the new realities of the 21st century. It’s up to you to decide if you want to make the focus of your life technological, focused on new innovations to drive society forward, or essentially human, focused on the age-old struggles of trying to get along, work together, and find happiness, or some combination of the two.
However I can tell you this:
Whatever you decide to do with your life, it’s going to be really, really complicated.
Science and technology is complicated. History and politics is complicated. People are complicated. Figuring out how to be happy, and do simple things like take care of our kids and maintain friendships and relationships, is complicated.
In order for you to navigate the increasing complexity of the 21st century you need a world-class education, and thankfully you have an opportunity to get one. I don’t just mean the education you get in class, but I mean the education you get in everything you do, every book you read, every conversation you have, every thought you think.
You need to optimize your life for learning.
You need to live and breath your education.
You need to be *obsessed* with your education.
Do not fall into the trap of thinking that because you are surrounded by so many dazzlingly smart fellow students that means you’re no good. Nothing could be further from the truth.
And do not fall into the trap of thinking that you focusing on your education is a selfish thing. It’s not a selfish thing. It’s the most noble thing you could do.
Society is investing in you so that you can help solve the many challenges we are going to face in the coming decades, from profound technological challenges to helping people with the age old search for human happiness and meaning.
