Random thoughts at mid year 2007 - advices to young scholars
Two fleeting thoughts:
First, this week is the start of the annual world-famous bicycle race – the Tour de France.
For this event the most famous personality has to be the American, Lance Armstrong
who battled and survived cancer, and won the race for the unprecedented seven continuous
times before retiring in 2005. At the time the newspaper "USA today"( issue dated
7/21/05) , carried an article about Lance Armstrong. The article raise the question how
can an athlete who survived cancer and at an age most athletes have retired from
competition accomplish this feat? The answer: RELENTLESS AND UNCEASING
EFFORT AT IMPROVEMENT OF HIS SKILL. The article explains how he test every
minute aspects of cycling from equipment to technique to body position non-stop even
during the competition. It was he who discovered that pedaling standing up when going
uphill is less tiring than sitting – a practice now adopted by everyone. But Armstrong
does not rest on his laurels and continues to innovate every year, which is one reason why
others can copy but cannot catch him. (private thought: China being a nation of cyclists.
When will the first Chinese win the Tour de France?) Note added 5 years later on 10/22/2012: The last few days,
it came to light that Armstrong and many others were involved for many years in an world wide conspiracy of doping in the sports of cycling. As a result, the entire sports of cycling has been exposed and may never recover. What a mess.
Same thing applies here to giving technical presentations and talks. For scholars young
and old, how many of you realize during a talk or during Questions&Anwsers that
something could be done differently for certain aspects of a talk? I bet almost all of us do.
But how many of you return home and makes the change on the slide or PowerPoint
presentation even if you know you will not give the talk again? I seriously doubt many
people do it. But it is making that change that will enable you not to make the same type
of mistake again and do better next time. Young scholars, if you want to advance in your
career, you will do well to remember the example of Armstrong.
Second thoughts deal with a much narrower topic of my profession. I had the honor and
fortune of creating the topic and coin the term "discrete event systems" in our field of
systems and control during the late '70s and early '80s. Now there is an international
journal devoted to the topic and a biannual international conference (WODES)
workshop on Discrete Event Systems
on the subject. Last year, I was invited to give a banquet
address at the WODES 2006.
Unfortunately that conflicted with my visit to China, The World Congress on Intelligent
Control and Automation (WCICA'06) in Dalian, and my duties at Tsinghua University .
So, I wrote a short paragraph and asked my former student and colleague, Professor
Christos Cassandras to deliver it for me at the WODES banquet. The following is a
verbatim copy.
Remarks of Yu-Chi Ho read by Christos Cassandras at WODES'06 Banquet
Dinner, July 11, 2006
Good evening, everyone, from half way across the globe. I am honored to be asked to say
a few word on the occasion of this WODES conference. From a humble beginning in the
mid seventies with aerospace guidance and control changed to manufacturing automation
and management, discrete event systems has grown substantially. The discipline not only
provides a new branch of systems for control involving not differential equation model of
dynamics but also ushered in the integration of control theory with operations research
and computer science. I was lucky to be present at the dawn of creation and am thankful
to all of you for the advancement and development of this subject.
To maintain vitality and innovation of the discipline, I urge our field always be problem
rather than methodology driven. Only after the former seed planting and germination can
the latter grow and flower.
Best wishes to a wonderful future. Good evening. Yu-Chi Ho
The last paragraph of the above remark is something I firmly believe in and has served
me well in the past 50 years. Young researchers take note!
