					 Newsletter – August

Dear alumni and friends,

Time really flies. Another year has gone by, and it is time for our third Annual General
Meeting and presentation of the third set of accounts – on September 22, 2007. There will
be a dinner after the meeting at Golden Bridge Restaurant in NYC Chinatown. You can find
the details on page 2.

At the last dinner in April, we had mentioned a possible joint function with the East Canada
association in August. Due to the high cost for hotel accommodation and other issues, the
function is postponed to a later time to be determined by the Board of the two associations.
We will keep you posted on any development in this respect.

Like the six months before, there were 2 functions in the last half year: spring dinner in April
and hiking in May. Brief reports on these functions can be found on pages 2 and 3.

Remember we announced that one of our members, Professor Chung K Law of Princeton
University, won the 2007 Outstanding Alumni Award from our university? Professor Law (Ed)
had taken time out of his very busy schedule to tell us something about himself and his area of
expertise. He has also sent us the powerpoint file on his lecture at our university earlier this
year. Please go to pages 3 and 4 for the article.

After learning a bit about aerodynamics, how about something about travel. Our own
treasurer, Michael Lai, a travel expert, wrote his first “Ask Michael” column (page 5). It’s a
long time in coming, Michael!       OK, OK, we know how busy you are!!! If you have any
questions about travel, feel free to send Michael a note and he will try his best to answer you.

Last but not least, you can find another two recipes on Soups for Health on page 6.

Before we end this note, we would just like to remind you that our university will be holding its
70th Anniversary Dinner on November 9, 2007 in Hong Kong. If you have time, do make an
effort to go. If you can go and would like to sit with fellow members, please let us know.

If you wish to contact us on anything, send us a suggestion or contribute an article for the
future newsletters, please send us an email:, or call Alice Chan (732)
967 1946 or Kari Yuen (718) 391 2345.

With warm regards,

Your Board of Directors

Annual General Meeting on September 22. 2007
The third annual general meeting of the Association will be held at 6:30pm at the Golden
Bridge Restaurant (see below) on September 22, 2007. The Board will present a
report on the past year and the accounts for the year ended May 31, 2007 for members’
approval at the meeting. Please come and attend the meeting, whether or not you will be
joining the dinner afterwards.

Annual Dinner on September 22, 2007
The annual dinner will be held in Chinatown in New York City as always. There are however
two things which are different. Firstly, we found that the restaurants have
increased their prices. Therefore, we have increased the price for the dinner by
$5 per person. The second change is that we will not ask you to prepay. If you
are coming to the dinner, please just complete and send the form at page 7 to
us by mail or email. Payment will be collected at the restaurant.

The details of the dinner are as follows:

Date: September 22, 2007 (Saturday)

Time: 7 pm [The annual general meeting will be held just before the dinner.]

Venue: Golden Bridge Restaurant, 50 Bowery, Chinatown, New York, NY 10013

Price: $30 per adult/child of 12 and over; $20 per child of 6-11, free for child under 6

Please respond by September 14, 2007 so that we can confirm the final numbers to the

Spring Dinner on April 21, 2007
There were two full tables of alumni and family attending the dinner. There were a new face
and old friends who had not attended our functions for quite some time. One member had
grown a beard since the last time we saw him. Some of the University’s 70th Anniversary
souvenirs were brought back from Hong Kong and shown to the interested alumni. The
Alumni Affairs Development Office had contributed some souvenirs for the lucky draw. This
time, the Board members appeared to be the luckier ones as most of them won a prize –
certainly all the female Board members did!

Hiking Function on May 20, 2007
It had been raining during the days leading up to the hiking function. Thunderstorms were
predicted for May 19, the day on which the hiking was to take place, so it was postponed to the
“rain date” of May 20. A total of 12 alumni and family/friends participated in this so called
easy hike. The weather was comfortably warm and the sun was out. The view along the trail
was excellent. Was the hike easy? Well, that depends on who you asked. But considering that
one alumnus could carry her baby daughter on her shoulders for most of the hike, it should
not be too difficult, right? One major attraction of the trail is the Tripod Rock. The “stronger”
ones of the group took turns to “support” the rock – using their legs, shouldering the weight
on their back, etc. Go to the link below to take a look at the photos, especially of the 2 cute
little girls who came with their parents:

Introducing Myself to the PolyU Alumni in Eastern USA
                                                                      By Professor Chung K (Ed) Law

Alice Chan asked me to write something about my association with PolyU, what I have been
doing since graduation, and what I am doing now in terms of research at Princeton University.

My enrollment at the Hong Kong Technical College, the predecessor of PolyU, was somewhat
accidental. I became quite interested in science and math when I was a middle school student
at Kiangsu-Chekiang College, and got this great desire to learn more than what was offered by
the regular curriculum. Somehow I heard about the ordinary certificate program offered in
the evenings at the Technical College. I applied and, to my surprise, was accepted, and even
exempted for the first year. The following two years were a period of pure joy in learning. I
would stay around after classes in my middle school to finish the homework, grabbed a bite
somewhere for dinner, and took the ferry from Hong Kong to Kowloon for the evening classes.
Consequently I was able to finish the program in electrical engineering at the Technical
College at the same time I graduated from Form 5 from my middle school, in 1965. The
ordinary certificate from the Technical College also turned out to have an unexpected benefit
as I used it, together with other records of merit, to gain admission to universities in the States
and Canada in lieu of one to two additional years of study in Form 6.

My ensuing activities can be run in fast forward – I got my B.S. in physics from the University
of Alberta in 1968, M.Sc. in aerospace Studies from the University of Toronto in 1970, and
Ph.D. in Engineering Physics from the University of California at San Diego in 1973. I started
teaching as an associate professor at Northwestern University in 1976, going through the
academic ranks there, and joined the Princeton faculty in 1988, where I am the Robert H.
Goddard Professor. As a tidbit of information of interest, two Goddard Professorships were
established at Princeton and Caltech in the early 1950s by the Guggenheim Foundation in
honor of the pioneer in rocketry. The first holder of this professorship at Caltech was Hsue-
Shen Hsien, the legendary Chinese aerospace engineer who, having been unfairly and
unjustifiably persecuted in the US in the McCarthy era of the 1950s, returned to China to build
up her program in rocketry. It is therefore a particular honor for me, as a Chinese and a
fervent admirer of Dr. Hsien, to be the holder of the same chair that once was occupied by my
childhood hero.

My re-connection to PolyU was again quite accidental. During a casual conversation with a
professional colleague of mine, Professor John Lee of McGill University and world leader in
aerodynamics research, we realized that we were both alumni of PolyU, only that he graduated
from the regular program in the late 1950s. John was selected as a PolyU Outstanding
Alumnus in 2003, and together with Professor Chris Wong, Director of the Industrial Center
and himself a 1997 Outstanding Alumnus, and Professor Ron So, former Chair of the PolyU
ME Department and an alumnus of Princeton, engineered my selection as a 2007 Outstanding
Alumnus. The award ceremony, held in April this year, was impressively organized and
joyfully celebrated. It was a particularly emotional homecoming for me, 42 years after
graduation, and seeing what has become of my alma mater – an active center of excellence in
technical education and research.

My research interest is in what is conventionally called combustion. Fundamentally, it deals
with the interdisciplinary study of fluid mechanics and chemistry, with intense and large
amount of heat release. Phenomena that readily come to mind would be the combustion
processes in automotive engines, aircraft gas turbines, rockets, and domestic and industrial
furnaces and boilers (and the gas range in your kitchen!). Issues of interest here are the
energy efficiency, pollutant emissions, and greenhouse gas emissions responsible for climate

Interests in combustion actually go much beyond energy and the environment. Think of the
detection, prevention, and mitigation of urban and forest fires, of urban and industrial
explosions (e.g. in grain elevators and mine galleries), and of the explosions of spacecrafts (e.g.
the Apollo and Columbia accidents). Think of the health hazards of cigarette smoking, which
is just a slow form of combustion that we call smoldering, and the potential service to mankind
by devising a healthy cigarette (but is this an oxymoron?). Think of formulating alternate fuel
sources that would replace petroleum whose reserve will be depleted within the next century.
Think of the sources of heat and power in our attempt to colonize the Moon and Mars,
recognizing that there is no atmosphere on the Moon and mostly only CO2 in the Mars
atmosphere (Can CO2, a nominal fire suppressant, support burning?). Now let’s really stretch
our imagination and be cosmic. The astrophysicists still cannot explain the massive
phenomena associated with supernovae, which are stars of the mass of a sun and the size of an
earth that would spontaneously explode and be consumed in a matter of seconds, emitting
light brighter than an entire galaxy. It was suggested that it was one of these supernovae that
the three wise men followed to find baby Jesus. To a combustion person, the nuclear reactions
occurring within these stars are not dissimilar from the chemical reactions, and the turbulent
motion within the stars would bear much similarity with those within the automotive engines,
including shocks and explosions that produce the engine knock, based on which gasoline is
graded (Look for theses designations and numbers on the gas pump next time you gas up:
Premium: Octane Number (ON) = 93; Regular; ON = 89). So we have come a full circle in my
introduction of combustion to you, back to engines!

       I gave a general lecture on combustion during my visit to PolyU for the Outstanding
Alumni Award. I might have sent the lecture material to Alice previously. Anyway, I attach a
pdf copy for your perusal [Note: Due to the size of the file, instead of attaching it to the
newsletter, it has been posted on the Association’s webpage at]] .

      I look forward to meeting all of you some time soon, possibly at the next meeting on
September 22.
Ask Michael                                                         By Michael Lai

I am finally in business! My first installment on Travel Q&A. Thanks to the
editors of our esteemed Newsletter who allow me to have the space here. Last
but not the least, thanks to those who sent in their questions via emails and
letters. Due to the limited space we have, I can only select one question to
answer first.

“How do I find the lowest airfare?”

Short answer is to email me.

But, I suggest a more technical way to do it yourself as follows:

1. For domestic airfares, first go to a couple of the ubiquitous websites: travelocity, orbitz,
expedia. One popular site,, actually searches all the other travel sites for

2. Once you establish a baseline for the fare between the two cities, then go to the airlines'
own site to verify that indeed that's the lowest fare. A lot of airlines guarantee their own sites
offer the best fares available.

3. It is always better to book flights via the airlines' own sites as, when changes happen, you
will need to work with the airlines directly. Although some people argue that you can do it
anyway, I have often been asked by the airlines to contact whoever I bought the tickets from.

4. For international fares, it's a lot more complicated. This is particularly so when there are
consolidator's fares available in the specific markets you are traveling to, e.g. Hong Kong and
Asia in general. The good news is that a lot of airlines are trying to get more business to their
own website by offering discount coupons or they cut fares occasionally to almost match with
wholesale prices.

5. I recommend also to subscribe to fare alerts via any of the travel sites. Also, sign up for
your favorite airlines' e-fare weekly updates etc. That will keep you abreast with what the
current market fares are.
