Dear Sir,
I am Stephen W. T. Kwan, a secondary teacher in Hong Kong.
Your java applets are too amazing that I cannot help writing to you immediately.
Would you please mind telling me how you develop these kinds of programs and
the time needed to do so?
Actually, I want to develop similiar programs myself in Hong Kong.
You can contact me through my e-mail address swtkwan1@hkstar.com.
Thank you for your attention.

Dear Professor Fu-Kwun Hwang:
This is the first of two emails I will be sending you.
I have been familiar with your work for about a year now. To say the list, it is impressive.
I am an assistant professor of physics at MS State University and I try to use the Web for instruction.
I am not a Java programmer. I wrote some stuff with JavaScript.
The URL for my class is: http://webphysics.ph.msstate.edu/2213.html
I am still working on the content and would like to eventually include some of your Java applets.
Obviously maintaining links to your Web site and proper credit.
I have noticed that you have your applets mirrored throughout the word (which is nice)
and I am wondering if it acceptable for you to add another mirror in our server.
I am also interested in having a copy of the applets to run of laptop that is not connected to the Web.
Actually, I am giving a talk about resources on the Web for teaching physics to high school teachers
on the 20 th of February, and I hope to be able to include some of your applets.
I will write a page with links to the applet in your site that I will use in the presentation then place it on our server.
I appreciate your help. You are doing some neat stuff there.

I am a professor of physics at the Royal Institute of Technologu in StockholmSweden.
We do teach Java for programming in Science and I came across your web pages.
Although we do teach Java for Ph.D. students I think there is something that could be learnt
from your beautiful pages. Maybe we will also extend the course to MS levels.
The problem is that we are in physics and Java should be taught by the CS dept, but will they do it our way?
We may try to suggest a course and then some of your web pages could be very useful to the students.
I would therefore like to ask you about your plans etc.
I would hate to have made refs to your pages and then they would disappear one day, smile.
Also, you may have some new ones in mind?
I think something with the uncertainty principle would be very useful. Have you ever considered this?
I am very open for any form of collaboration on this future teaching project.
You can find examples of the present course on the web.
We plan some lecture notes and I hope I can make ref/use some of your examples?
Looking forward hearing from you

Dear Professor Fu-Kwun Hwang
My name is Taha Mzoughi and I am an assistant professor of Physics at Mississippi State University. I am currently compiling a library of Web-based simulations and animations for a CD-ROM to accompany the forthcoming third edition of Jones and Childers' CONTEMPORARY COLLEGE PHYSICS book. The library will supplement software developed for the book by McGraw-Hill publishing. The intent is for me to write an HTML page including a link to the selected web resource along with credit to the author and text relating the animation/simulation to the book content. In some cases, we might need to include operation instructions. To reduce problems due to web traffic and to changes in web addresses we prefer to include a copy of the actual animation/simulation on the CD.

As a bound-in supplement to the book, the CD is intended to provide the student with increased resources and a pathway to the resources available on the Web without augmenting the cost of the book. We are mainly interested in material that students can access for free on the Web. Credit to authors, links to their sites, and any other material that we (or you) feel is needed will be provided. I particularly like some of the simulation/animations/applets you have developed and think that they are excellent candidates for the library. The applets I am seeking permission for are at the following URLs: ....

hrough this email, I am formally asking you for permission to include your simulation/animations/applets in the Contemporary College Physics CD. If you accept this offer, McGraw Hill Publishing will send you a printed version of the agreement. Obviously, to include your software in the CD, we need assurances that you have full rights on all of its content. If you are not the appropriate person to contact for permission, please let me know whom to contact. Agreeing to include your simulation/animations/applets in the CD will give McGraw Hill Publishing a NONEXCLUSIVE right to distribute the software free of charge with the book.

I believe your simulation/animations/applets to be an excellent educational tool and I would like to help get more students to take full advantage of it. I am looking forward to the possibility of working with you on this matter.

Please note that the publishing schedule is tight and I need your reply ASAP. You may contact me at mzoughi@ra.msstate.edu (phone 601-325-2923) or contact McGraw Hill Publishing directly by sending email to David Dietz at david_dietz@mcgraw-hill.com. Please include your "snail mail" address in your reply.


We request permission to use the material in Jones/Childers third edition and subsequent editions of that book (this is standard for excerpted material), but not in other books. The permission letters reads:

We request your permission to include the following material on the bound-in CD-ROM in this and all subsequent editions of the book, including versions made by nonprofit organizations for use of blind or physically handicapped persons (and in all foreign language translations and other derivative works), for distribution throughout the world.

[Taha Mzoughi] I hope that this is fine with you. Your Applets are great and students and teachers will greatly benefit from having them readily available. I have made a presentation Friday to about 60 teachers from around here. I showed some of your applets and they loved them. Most of the teachers still don't have internet access readily available. Remember also that you are retaining the right to publishing the applets elsewhere.

your applet works fine, thanks a lot.
We want to use it offline, for non-commercial demonstration.
I've mentioned you and made references to your site at this local page, however.
Some suggestions/questions:
1. One goal is to maximize/minimize :-)
the flow. But it's so easy, with setting velocity and acceleration to max(min), isn't it?
2. It would be fine to see the flow rate in an extra text field,
cause this is the much interesting output (for me).
3. Perhaps, a "history" of the last flow rates (then you can better see,
whether you have success in maximizing flow rate or not).
Could be a simple text table (over a time intervall), or a graph.
Ciao, Uwe

Dear Mr. Hwang,
When I meet the physics teachers of the other schools in Singapore,
they give good comments about the mirror site of Virtual Physics Laboratory.
I think your Java Applets are popular in Singapore.
I am therefore interested to know how many people come to visit Virtual Physics Laboratory
and use your Java applets everyday.
Mr. Hwang, can I add a counter on the contents page?
If so, please let me know.
Thank you.

I'm a student at Olympic College in Bremerton, Washington currently enrolled in a physics class.
We are studying vectors, freefall, velocity/acceleration and projectile motion.
Your web page is great!
I think the answer to the question of case one about the green circle is the arc of zero vertical velocity.
When the object reaches zero velocity, acceleration remains a constant 9.8 m/s(sq) downward.

Fu-Kwun Hwang,

Many thanks for the java applets that you so kindly sent me. The
teachers in Singapore were very impressed with them and I am sure that
your mirror site at the Singapore Chinese girl school must be over
worked. The implimentation of these java
applets together with others that I have obtained from programmers
around the world and my successful integration of computer based
technology into the science curriculum has resulted in my nomination by
the college for the Prime Minister's Award for Teaching Excellence
(Canada). This
is indeed an honour for me and I am required to present some of my work
which obviously includes some of your java applets. My work is purely
pedagogical in nature and focusses primarily on use of technology as an
effective teaching tool. It also involves how various systems and
strategies can be adapted to fit various learning styles.

I would therfore like your formal permission to use these applets and to

submit copies of them ( with full formal acknowledgement of your
authorship) in support of my nomination.

Many thanks for your help and support.

Dear Fu-Kwan Hwang,
     I am a physics teacher at Dartmouth High School in Dartmouth
Nova Scotia Canada.  I discovered your applets a couple of weeks ago
and am still exploring them.  They are an invaluable resource for me,
my students and for use in teaching in my classroom.  I have used one
so far and built my lesson around it...a lesson I had taught before
but it added that extra pzazz and interest for my students.  We were
using the reaction time applet.  I showed them how to do the
calculations using the motion equations and then we gathered data for
stopping distances using the applet.  They were also thrilled to see
the internet used in such a meaningful way...they have become
skeptical of the junk out there.
     Please accept my sincere thanks for the excellent quality of the
applets and I hope your work is able to continue.

I could do it myself I even have this Flash chat program. But I dont think people can be bothered registering on another site just to chat. Their have been about 3-4 people since I registered here who have made their own chtrooms and after about a week these sites have closed because nobody bothered with it.

The only way I think it will work on this forum is if they actually add this feature here. You could always talk on tatysite.
I think they have a chatroom feature.

This is not an advert for tatysite
