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
Thank you for your attention.

Hello, I was looking at your site and I was wondering whether it would be possible
to mirror it here at this university. Would you please let me know if this is possible.
Then I would contact our system manager 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:
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.

Subject: Java and Physics
Date: Sun, 15 Feb 1998 09:15:22 +0100
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 Sir, I'm also a Physics teacher, O level, and I am interested and fascinated
by the Java Applets you have created..... they are really good.....
I find them very useful for teaching and demonstrating certain concepts in physics....
I am wondering how do you write a Java Applet....
I have the Java Programmer Kit downloaded from Sun.... but don;t know how to use it.....
please advise
Thanks in advance.

Publishing Your Applets

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 (phone 601-325-2923) or contact McGraw Hill Publishing directly by sending email to David Dietz at 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.

Dear Mr Hwang
I have found your java applets especially those on waves and optics to be particularly facinating and informative.
So much so that I have begun to use them extensively for my grade 11 physics students
at Appleby College in Oakville, Ontario, Canada. ...

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.

Hi! I'm a physics teacher in Blantyre High School in Scotland
and I've just discovered your Physics demos site.
When I return to school tomorrow I'll be directing my class to your site first thing.
Well done and thank you...
I'll be a regular visitor from now on.

Dear Mr. Hwang,
Hello! I am a student of the National Tsing Hua University(NTHU).
Maybe you've heard that the Material Science Engineering which is my major.
I'd like to appreciate the great jobs you've done.
At first, I come to this website because of my final-term physical report.
However, when I view the first exam, I can't help finishing all items in this site.
Well, that's all what I want to say about this special work.
Have you a happy time in teaching.
Your sincerely, Robinson Wang '98.6.14

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.
