I have checked the CD kindly sent by you and it worked properly; earlier there was some problem due to my computer.
The programs are excellent as teaching and visualization material for Physics and I congratulate you for your very successful efforts. You might have done lot of hard work to get the ideas correctly with the proper visualization techniques in such a large number of topics. I have not seen any such Cd in Physics so far. I think it will be very useful for everybody and it should be made available at a suitable price to all schools and colleges. I hope you will be able to do this with the help of some publishing agency.

Although I have used your simulations for some time in physics teaching, I have only recently had access to a data projector which allows me to refer to them as I introduce topics which have LONG cried out for a dynamic representation of the relationship between variables etc.

While I wrote some like a few of these in basic using the original apples, I ran out of steam eventually.
Congratulations on you very useful work. More use to me than many research publications may be :-)

mjoyce@iinet.net.auI very much enjoyed your applets.
I have no formal training in any of the fields you have covered, but you apps have shown me something from all of them.
Very intreresting.

In particualr, I found the Simple Harmonic Montion, quite hypnotic.

Dear sir,
I'm a researcher at the university of Pisa.
I'm working in the organization of a science exhibition, which will take place in Pisa from the 5th of May. I happened to see your applets, and I  appreciated them very much. Would it be possible to translate the page texts in italian and to place them in our exhibition, properly credited with the author name and your page address?
I wish to stress that the exhibition is for educational purposes, and the entrance will be free.
Please, let me know if give me your kind permission to do that.
Thanks.

Dear Dr:

Surendranath Reddy.B

My name is Luis Germán Torres Peñuela. I am a physics teacher from

Colombia SouthAmerica.

I teach in public schools as well as in a Center of Biophysics Research

here in my small village "Cerca de Piedra" CHÍA COLOMBIA, S.A., for

free, since my income comes from a personal bussiness that I own in

Automatic Industrial Control.

Since colombians students from public schools specially in small

towns like Chía, they have very limited opportunities to use high- tech

facilities, right after visiting a Web Site with your Applets, I had

the idea of asking you for permission to use your Applets for teaching,

and also to have them open to the students that visit my site

www.chiacom.com , which is a Web Site dedicated to social service,

where EVERYTHING IS FREE and we have no charge at all for any

publication. The site has many tool for students related to their town

(Chía), maps, history, etc., and of course to add your applets (I

already downloaded them - in a way to express it - and translated the

literature to spanish) would be something out of any expectancy to our

visitors, students, teachers, due to the limitations that we have,

including the very incipient skills tah I have in order to be able to

develop such tools.

Just in case you agrre, I also ask for permission to add a web page

with your personal information just like the one titled "ME" where you

have a short and humble description of who you are.

Regards:

Luis Germán Torres Peñuela.

chiacom@chiacom.com

I use your very nice Physics Java Applets in my Introductory Physics Course for students of Computer Science at the University of Karlsruhe (Germany).

It would be very convenient to have them on my local laptop to reduce time losses for loading, cabling etc. before the lectures.

So far I was not very successful in saving your Applets on my laptop. Would you be so nice to give the permission to do that and in that case some advice how to do that?

Many thnaks in advance and best regards,

Yours Wolfgang Kluge.

I would to congratulate you on a wonderful collection of java applets. They certainly enhance the teaching of physics. I have notice that you have a mirror site at Mount Alison University. We would like you to consider using us also as a mirror site for your applets. We have used them extensively to train teachers on the integration of technology in the class room. However, when we have large groups accessing your site(s) similtaneoulsy internet access slows down considerably.

I visited your Tripod website with the Java applets on waves. It is

possible to download the java applets as stand-alone files that I could run

off-line in case the network in my classroom was down or your site goes

I _love_ your site! Thank you for putting it up. I've told

every physics and/or physical sciences teacher I know

about it. Well done.

Currently I am a physics of acoustics teacher at the

San Francisco Conservatory of Music in the US. The students

where I'm teaching don't have the tools to analyze things

mathematically, so I've been working hard to help them

understand things conceptually. To this end, I've hunted

down and/or made numerous visual aids. The 'net has been

great in this regard; there are a number of really wonderful

animated gifs, as well as applets. Generally what I do is

load these gifs and applets onto my laptop, so that I can

bring them to show my students. Unfortunatly with yours, I

cannot save the applet itself. The only way for me to access

it is to be online (which I cannot do from the Conservatory)

or load up while I'm online and then go to teach without

turning off my laptop. This last bit is difficult, as the

battery is limited, and "hibernate" doesn't seem to work

so well. Is there any chance I could talk you into letting

me have a copy of your Harmonics applet? Others would be good,

too, but that's the one that would be most useful and

appreciated.

Many thanks,

Having recently gone through your website and having viewed the miondblowing java applets you have developed, it indeed amazes me as to how a person could have  gained such in-depth knowledge on such abstract topics of physics and yet be so much up to date with today's world as to use self made java applets as a teaching medium. 

 My name is Richard Thompson. Basically a citizen of the United Kingdom, I am living in Bangalore for one year as an exchange student and am studying at the International School, Bangalore. A student of Physics myself, i was wondering if i could seek some guidance from you in a few topics i find particularly uncomfortable. If your hectic schedule restraints you from sparing time for the same, though I hope that is not the case, i would be greatly obliged in receiving as little as a reply to this mail.

I was searching the web for an animation to illustrate that the frame of reference determines "reality," and I found your wonderful applet,

http://www.schulphysik.de/suren/MoveOnDisc/MoveOnDisc.html

 

I have a few animations on my website that you may find interesting, although the topic is rather different – statistics.

http://www.StatisticalEngineering.com/central_limit_theorem.htm

 

Anyway, the reason for writing is to ask a favor.  I would like to use your applet and tie it to the unlikely topic of small-sample influences in estimating probabilities.  I would reference you as the source, of course.

 

How could movement on a disc have anything to do with statistics?  Consider this:  After taking your measurements, you calculate the mean and standard deviation (never mind that you haven’t checked if the data should even be modeled as Gaussian) and calculate that a 0.1% future observation should be -3.09 of your calculated standard deviations from your calculated mean.  Engineers (I’m an engineer) do this all the time.  *Without regard to sample size.*  Well, it’s wrong.

 

That’s because you do not know the true mean, mu, nor the true standard deviation, sigma.  You are basing your perception of the world on your measurements Xbar and S.  And you are doing what the observer on the rotating disc is doing when he insists the the motion on a disc has a curved trajectory.  Is he wrong?  Well, that depends ... on the frame of reference.

 

Since you can't KNOW the true mean and standard deviation, you use Xbar and S, as estimates for them.  But samples from a Normal density ARE NOT THEMSELVES NORMAL, RELATIVE TO THE SAMPLE STATISTICS Xbar and S.  (Of course they are Normal relative to the unknown mu and sigma, but relative to Xbar and S they have a Student's t density which depends on the degrees of freedom.)  I have a simple simulation - I'll send you the code if you wish - that illustrates this.

 

 The simulation proceeds as follows:

1.  Simulate 100,000 samples of ten.

2.  For each sample, calculate the sample mean and standard deviation.  (The sd uses a n-1 divisor and is thus unbiased.)

3.  For each sample, erroneously calculate the lower and upper bounds based on z.normal=  3.719016, which is the number of standard deviations from the mean of a standard normal density necessary to have p=0.0001.

4.  Compute the fraction of the known standard normal density that would fall below the sample's lower bound, and above the sample's upper bound, and record these for each sample.

5.  Then average the results, showing the average fraction below/above the sample's limits.  In this example the actual fraction failing is 0.0031.

6.  Compute the ratio of this to the fraction expected from the normal, i.e. p=0.0001. 

7.  Compute the theoretical value for this ratio based on Student's t and Normal z, 31X in this case, where p=10-4.  If p=10-7 the failure rate would have been underestimated by nearly 4000X.  (That's a factor of 4000, not 4000%).  These are not negligible errors.

 

Boy!  What a wind-bag I am! 

 

Anyway, here’s the request:  May I have the code for your applet?  (I’m not a JAVA code-writer.)  I am giving a talk in a few weeks and would like to show your applet on my laptop, but will not have internet access.  I will understand if you do not want to share your code, but would be very appreciative if you would share it with me.

 

Thanks.  And thanks for a great webpage!

I've very much enjoyed some of your wave motion applets for my high

on disk or CD so I don't have to have a live web connection in the

classroom? I tried to use them today, but couldn't because of our

schools web connection problems. I'd be interested in compiling a CD of

many of these applets, for physics teachers in general. There are lots

of applets on the web, but being on the web requires a live web

Greetings!

I like your applets and would like to use them. I am a Professor of Physics at the Univesity of Wisconsin and teach am undergrad course called Physics in the ARts for liberal arts students.

I do not want to use your work without permission and without giving proper credit. I would use the applets for such things as simple harmonic motion, transverse and longi waves and harmoics.

I would have three different options, depending on your permission:

1) use the applets only in lecture with video projector

2) cut and paste freezed frames for my lecture notes with I plan to give to the students on CD

or, best of all, if you permit:

3) copy applets into CD's given to each student.

Please let me know what the proper procedure is to avoid copyright infringement - but even if not copyright protected I want to be fair and acknowledge you work by name (please give me the proper way to refer to you as author of the applet)

keep up the good works!!

Hello there,  I am producing an educational website and would love to place some of your applets on my site. If you are uncomfortable with this idea, I would like to link my site with your’s so young students would have an opportunity to interact with your applets.  I think they are really helpful for the visual learner.  I see so much potential in letting students interact with different parameters to see and understand the variables with in a physical system.  Thanks for all your work.  The site I am building is going to be vast, when it is up and running, and having access to your inventive applets would add a great deal to the interest of the site.  Please let me know how you feel about this idea.  If I can put them on my site I will give you full credit and will place a link on my site to yours.  Thanks for your attention.  

Talk to you later! 

Jeff Hybarger/ Asst. Principal Las Vegas Nevada

My name is Jeff Hybarger and I am presently developing an educational website for students from 3-12th grade.  I came across your compelling site and was fascinated by the applets that you are using.  I am interested in either linking to your site for learning purposes or, with you permission, obtaining (or downloading) some of you applets to reproduce them on my site.  For example, you have an applet that shows molecular movement.  I would like to produce a page that talks about this idea with kids, however the applet is what would make the concept most interesting. The fact that students can interact and make changes to the molecular model is very cool.   Let me know what options you suggest or prefer I use.  Thank you for your time.  Jeff Hybarger/ Las Vegas NV

I've enjoyed using your Forced Oscillation applet to teach my students about SHM, damping and forced oscillations in class. It is a very good demonstration of the concept to the students.

 

If you can increase the damping factor a bit higher so that critical damping and overdamping conditions can also be seen, it will be perfect.

 

Thank you for your hard work and sharing.

Most of your aplets are great! I have had fun testing them. I am going

to use many during my lectures for students (if you don't mind :-)).

One comment about the Roll aplet: changing the linear to angular

velocity ratio

is somewhat unphysical (sliding?). It would be better to change the

observed point

distance from the circle center with same effects.

LOVE THEM !!!
Thank you for sharing these wonderful educational tools.

Can you share the source code also?  I'd like to tweak them to make them specific to winter Olympics sports.  I recently did a talk on that subject at a local science museum (this is for small children, so it isn't as technical...)  I think it would be neat to be able to superimpose some of the applet code over video footage of the athletes then allow kids to interactively manipulate the applet inputs to gain some insight into the fundamental laws...

Thanks again for the wonderful web site !

I am an undergraduate student at Rutgers University, and I noticed your Applet programs on surendranath.tripod.com/Applets.html, in particular your Roll and Slip Roll Applets. I am doing a senior design project that entails translational and rotational motion of a golf ball during putting, and I noticed that your Roll Applet can show the path of a point, but your Slip Roll Applet does not.  Would it be possible if you could send me the sources of these two Applets so I could add the path of a point to the Slip Roll Applet? If I use these Applets for my senior design project I will add your name as the creator of these Applets.

I would like to use them in my class. I don’t have a

permanent connection at the Internet, so I would like

to use them offline but I don’t know how to do that.

Please send me an e-mail at gherman_lucia@yahoo.com

and tell me if exist any possibility. If not, please

send me the source codes of the applets.

I look forward to hearing from you.

With many thanks

We have about 50 students taking A-level physics and I know that they think a lot of your work, they are great learning instruments.

 

Do you sell your applets on CD.

 

We will BUY it if you do.

 

Please send details and costs.

 

 Keep up the good work, if ever you come to England I'd like to meet you.

 

I was recently asked to speak at Peterhouse College, Cambridge about Physics A-level in England, you got a mention!

 

Very best wishes

I have been impressed by your Virtual Physics Laboratory project.

I am currently involved in developing a site for matriculation examinations

in Physics for ORT network of schools in Israel. http://www.ort.org.il/en/

The site will include many simulations and exercises using the advantages of

the Internet environment.

ORT network include 70 high schools and thousands of teachers and students.

I believe that incorporating your Java applets into the site would be very

helpful for the students.

I would like to examine the possibility to use your materials as a mirror or

another way of cooperation and connectivity. All the credits will be given

to you or your institution.

Our added value will be to design and develop student activities in Hebrew

around these applets and we will be happy to send them to you translated to

English.

All the best

Yours Sincerely,

yes, your notes helped me to understand how this 3D works with java

"mathematicly", thank you !!

But how can I tell java that you can click on the figure anywhere and

then it changes the coordinates ?

How can I change the color by changing a parameter (for example in your

applet with youngs double slit experiment) ?

cheers and thank you for the help !!

As part of our non-profit educational outreach program, we would like to promote the use of Information Technology more actively among the school teachers in Singapore. We have recently searched through the web sites and we have found that your Java applets are extremely interesting.  Moreover, we also believe that your applets would help our teachers greatly in their teaching.

We would therefore like to seek your kind permission to use your applets for these educational activities that include a link from our web pages to our applets and the downloading of your source files for the applets to a Cdrom for distribution to the teachers.  Naturally, we will include a clause in the Cdrom stating that the resources are meant strictly for pedagogical purposes and should not in anyway be used for commercial purposes without the explicit approval of the authors whose contact address will be included in a text file for information.

We look forward to your favorable reply.

The Cornelsen Verlag is one of the leading publishers of educational

materials in Germany. In order to complement our schoolbooks, we would like

to make additional information available on the Internet for pupils aged

between 13 and 17. We hope that this will make Chemistry and Physics more

accessible for them and increase their enthusiasm for these subjects. This

material would be for non-commercial use only.

In the Internet we found the applet river and boat which we would like to

use as part of the free additional materials we intend to make available on

the Internet. The applet would be accompanied by text in German.

We would be grateful if you would allow us to use the applet in the context

described.

Thank you in advance for your help.

I´m a student of mr. krahmer (he has a mirror of your page at

raytracing and lenses. These applets are 2D, what have you done to

make this 3D-applet with youngs double slit experiment ?

By the way, I think your applets are really good - I´ve never seen an

applet with this experiment in the web so far !

Your physics applets are very clever.  The latitude/longitude demo was especially good, as was the use of color in Young's double slit applet.  Thank you for your hard work.

 

I would like to use your cross product applet in an online Multivariable textbook I am developing.  The textbook is not for profit, and will be made available to the public at no charge.  Your name will be displayed immediately below each applet, as will any other information you want to have associated with your work. 

 

This textbook is an outgrowth of an NSF grant I completed a year ago.  However, I am developing this book solely out of a desire to enhance student learning (in particular, my own students' learning).

 

I hope to have most of the textbook placed on the internet within the next two weeks, as I will be using it as a supplement for the Multivariable course I will be teaching in the Spring.  As soon as I have placed the material on the web, I will send the URL so that you can see the result for yourself.

I'm a high school physics teacher in New York, USA, and greatly enjoyed your applets.  I was wondering if I might download the applets themselves to use offline in my classroom since my class machines are not networked or connected to the Internet?  It would be a great supplement to the course, and I have worked this out with some other authors in the past.  All author attributions would be included on the machines.

Just a note to let you know how impressed I am with the physics applets

you have developed. They are of course excellent tools in helping one

understand key concepts related to physics.

I am presently teaching two high school physics courses on line and I

would like to ask your permission to utilize some of these applets as a

teaching tool in these courses. Students would find these illusrations

extremely useful as they would be able to visualize and in turn be able

to gain a better understanding of the key concepts they are studying .

I have createed some flash files related to the formation of images by

mirrors and lenses which I am willing to share if you are interested.

Thanks for your attention and I look forward to your response.

The Virtual Schooling Service delivers full course instruction in a number of subjects to students (non fee paying state school students) throughout the State of Queensland.  The students are located in schools where the enrolment in the subject is low or the school has difficulty providing a qualified teacher in the subject. Schools involved are mostly in remote regions although some are in metropolitan areas.

Delivery is twice weekly via synchronous voice/data connections where whiteboards and files are shared. Other student resources are placed on the State-wide Intranet for students to access in their other allocated school times.

In 2002 we will trial the delivery of Physics to an expected 20-40 students in 10-20 schools. Practical work is of course the more difficult aspect of this subject via this mode and a range of techniques will be used from student "hands on" to simulations, movies, calculator based electronics. Whatever is available and usable will be tried.

We are impressed with your applets on your web site and will certainly be directing students to view them.

However, all too often we have bandwidth problems with delivery and students have access difficulties and limits and we wish to ask your permission to use the applets in a more secure (for us) method. I list below a range of possibilities for your consideration on the understanding that we do not intend to profit from the use of the applets and that we will abide by whatever you decide.

1.      Place the applets (with full acknowledgment of the copyright) on a CD and mail out to our students in advance of the lessons.

2.      Incorporate the applets one by one into the appropriate sections of our course on the State-wide (secure) Intranet

3.      Mirror your site on the State-wide Intranet

4.      Mirror your site on the www.

We would be grateful if you would indicate if any or all of the above models are acceptable to you and under what conditions.

ou have been very kind in sharing information.  I will continue to work with the information you provided to complete my project.  Specifically, I am trying to calculate the radiation dose to our patients who undergo cardiac catheterization procedures.  The patient lies on their back.  The x-rays come from below the table at various angles.  I have to calculate the distance from the source of x-rays to the entrance of the patient skin surface.  Part of the problem involves the fact that the table can move longitudinally, laterally and vertically and the x-ray tube can rotate in both the y-z plane and the x-z plane .  Anyway, I need to work with the problem.  Please let me know if you have any ideas. 

 

Best wishes to you and your family.

Great job on your general physics java applets website.  It has been several years since I have worked with upper level math.  I am very interested in the equations used to create your example of a varying point in polar coordinates.  Would you be so kind as to send me a straightforward reference, or the equations used?  I am not really interested in the java aspect of things, but more on the math/geometry.  I am working on a project at work which requires me to be able to localize points along a sphere. 

Thank you for your consideration into this matter.

Thanks for sending the new file. I have forwarded it to Darren to do the necessary replacement.
Just so that I am sure to get the newer directory name the way you would want it, can you confirm that you want the name changed from "sb_reddy"  to "suren".
Getting the name changed is no problem.
We can also put a counter in the front page as you have wished.

I am teacher and researcher, and I am working in a research group, in

Passo Fundo University, UPF - RS, Brazil, with Virtual Laboratories in the

Internet. We've accessed your experiments in the web and we found them

very interesting, mainly because they are very realistic and interactive.

We'd like to insert them in an environment of constructive learning that

we are building, to be used in teaching of Physics.

This environment has for purpose to allow the students to accomplish

non-possible real laboratory experiments. It will count with a series of

other resources (reading material, discussion forums, extra activities,

exercises, etc.), in order to increase the effectiveness of learning of

the students.

Therefore, we'd like to know your possibility to supply us the sources of

the experiments below, and, in compensation, we intend to maintain its

copyrights, and also share our research results to you, when it is ended.

Hello Surendranath,

 

I took a closer look at number of your applets and found some that would be appropriate for our site.  As you can imagine, we have an enormous amount of information on our site in the form of animations, illustrations, other graphics, as well as our traditional text.  In most cases, we do not purchase rights of work, but rather work out a modest exchange with the author retaining full rights of his or her work to do as they please. 

 

What we offer creators of specialized new media such as yourself, in exchange for use of your content, is that you will retain full rights to your work, we will give you on-screen credit as the author, and we will provide you with a Encyclopedia Britannica 2001 CD ROM or DVD.

 

We are interested in a number of your physics applets, and it is an opportunity for your work to be seen by a world-wide audience.

 

Let me know if this an agreeable arrangement and I will let you know specifically which applets we would like to use.

Hello,

We are currently seeking authors of creative and educationally useful interactive applets/simulations to offer them the opportunity to showcase their work through our upcoming k-12 education site. We are not currently seeking to purchase ownership rights of work. We currently have numerous arrangments with others, and are open to various licensing scenarios.

If you are interested in having your work displayed as a part of Encyclopedia Britannica's education offering please reply to this email address.

Hi, my name is Jongilanga Guma. I dropped my course in Mechanical

Engineering because I was much interested in Computers. Now when I say

your applets, I was so hurt because of the great engineering things

that an applets can do. Can you please send me the source of those

applets I promise to "Reference" to you if you think I can still them.

Cheers

jongi@webmail.co.za

I was looking at their internet page, and this very good one, and the

applets is really very well developed, this message is to see if it exists

the possibility that you will facilitate me the code source of the applets,

to mount them in Spanish in the page of internet of the Technological

University of Pereira, in Colombia...

We are one of the leading secondary textbook publishers in Hong Kong. Besides traditional print media like coursebooks, teachers' guides, workbooks and wall charts, we also publish quite a lot of complimentary multi-media products like CD-ROM and web-supporting materials for teachers and students.

 

We found that some java applets on http://surendranath.tripod.com/Applets.html
are very well produced and interesting. It is a pity that the materials are not fitting well with the HK curriculum. As such, I would like to ask for your kind permission in allowing us to adapt the contents for HK students and teachers.

 

As the adapted materials will mostly be used on a free basis, please kindly grant us a free permission. We shall provide links to the original site and make proper acknowledgement.

 

If you have any queries, please feel free to contact me.

Congratulations on your marvelous applets and web site.

 

I write in my capacity as Physics Coordinator at Melbourne High School Australia.

We are an academically orientated senior public school in Melbourne, Victoria, Australia

 

I am planning a new web site for our Physics students and ask a favour of you.

 

I seek your permission to place some of your applets on our new web site along with appropriate credits and links to your site.

( any applets placed on our web site would be in a password protected area of the new site -allowing access to our Physics students only - about 300 students )

 

I look forward to hearing from you.

 

Yours Sincerely

Your forced oscillations applet is beautiful. Now you only need to add a way to change the initial position and velocity, so that students can see how the transient "dies" in the presence of damping and how the long-term motion is the same regardless of the initial conditions.

I was referred to your website as containing some of the best applets around. Unfortunately, I can't access it using IE 5.0 running on Mac OS 9.1 Your Applet Menu drops a menu which disappears almost instantaneously, so that I have no time to click on anything.
Things are even worse in Netscape, where I only see an outline without the Applet Menu title and where nothing happens when my mouse hovers over that area.

I thought you might be interested in knowing this.

Dear Sir

I will be honoured if our server is used as a mirror.

If you send me a *.zip I could talk with my director to allow me use the

server as a mirror.

Let me warn you that our server is only a few months old, and we are just

learning on how to use it.

I could also pick up some of your animations and include them in some web

pages I am creating. I will write

Your name as the author of the animation

A description on how to use

A description on how to apply them to Physics. For instance I have

already written a page on Snell law, that uses a JAVA animation send to me

from Germany, which generates several questions. In turn, I send the

reader to another animation (from Korea) which presents another aspect of

Snell law (how a fish will look at an object fro down under)

As you can see, as a not very developed country we have to tackle several

needs that may be particular to our environment.

Thanks again for your offer.

Please send the *.zip to this address.

Your Applets are superb!!!

They can indeed be used in the class, as I have done so myself with a computer projector.

They demonstrate principles extremely well in a manner that pupils can SEE.

 

I would like to thank you for putting them on the web for all to use free of charge.

I am sure many pupils world wide will also appreciate your efforts.

Yes I did write to you before requesting your applets on waves. I am

interested in the applets on kinematics, dynamics, and electricity. I

hate to bother you but there seems to be no way of downloading all the

files needed by each applet. Perhaps you could package them in a zip

file according to topic.

Our school year is nearly finished, so there is no rush for the applets

right now. However, they seem to be excellent for demonstrating the

specific topic for which each was designed.

Keep up the good work!

In fact, we have used some of your applets in a physicslesson about

oscillations.

We did not copy the applets, but provided a kind of link in our HTML

Sorry, the whole site is in Dutch, I hope you can figure it out..

My assistant, mrs. Marjolein Koopman, has tried to contact you to ask for

First I'll introduce myselve:

My name is Hans Brunt and I'm a physician.

I'm a teacher and also I write schoolbooks for students from 13 till 23 years old.

The methode I wrote is: "Systematische Natuurkunde: ( Tranalation: Systematic Physics).

70 % of the students in Holland use these methode.

 

So I saw on internet that you wrote a lot of physic applets and I show it to my students.

They used it very well and said that the applets were beautiful.

 

I also make software which are made to use same with the schoolbooks.

 

My question is if it is possible that we can use your applets together with my schoolbooks.

 

So I can translate the workspace. I think that your applets can break through in Holland.

 

I hope that I can see your e-mail soon,

 

Hans Brunt

I am a norwegian teacher (52 years of age)at a high school situated in Molde on the west coast of Norway. My topics are mathematics and physics. Through the web I have found your java-applets which I find very interesting. They are very informative and easy to use. I therefore now intend to take advantage of some of them in my physics group counting 25 pupils.

Thank you so much for your contribution to my teaching.

The applets work fine. I had to reconstruct the cframe.js Javascript

file in order to get it most of the applets to work, however. This

wasn't a problem, but those trying to mirror your site in the future

may not understand why the applets don't work. (I think if you just

include the cframe.js file in the zip file that would take care of the

problem.)

Thanks again. I found a few new applets that I had not seen before,

and they work great. I especially liked the "Charged Particle

Moving in a Magnetic Field" applet.

I have seen your fantastic java applets they are certainly very helpful to the

students.

I am a Visual C++ programmer and I have just started working on Java. I wish

to know how do you develop 3D applets that can be moved with mouse into

different positions (like a molecule viewer).

This wiil be a great help for me.

I would like to have a copy of all of the Physics applets - I do not require

the math applets.

They will be most useful at school!

Currently I am teaching Cambridge A Level Physics at Senior College in

Auckland, New Zealand.

Thanks again

Do you know if there is any way I can down load the applets to show my class

without being on the internet?

Thanks!

Thank you very much for the zipped file that you sent as an attachment. I have got the needful done by our people at the Computing Services and your files are now up on the server and accessible to all.
The URL for the site is
http://www.mta.ca/faculty/science/physics/sb_reddy/index.html
You will also see reference to it through our page that list some useful physics sites. The URL for that is:
http://www.mta.ca/faculty/science/physics/useful_links.htm

Our institution does not give access to its web servers to other than our University personnel. However should you make any changes you can send me a new zipped file and I shall get it installed. I am also giving you the email address of a member of our computer services department - Darren Spidell (dspidell@mta.ca). Darren is a faculty consultant for computer related purposes. If you send him a copy of what you send me he will also be helpful in getting things done. As a matter of fact he is the one who unzipped and put the file on the server this time. So you actually have two contacts and can be more assured of getting at least one of us just about any time of the year.
Prof. Hwang of NTNU will be doing the same thing for his mirror site with us. He will send me a new zipped file every few months and I shall put it up.
I hope you will find the arrangement suitable. It will certainly give your work an added exposure and give our students faster access.
Thank you once again for sharing your applets. Should there be any other queries please do not hesitate to contact me.

Regards,

Pravin Varma

Dank für die Grüsse (Dank fuer die Gruesse).

I tested ALL of your applets:

Congratulations ! They are all running on my Mac (with MS IE, latest Mac

edition). As I know from writing applets there are sometimes big problems

with some browsers or operating systems.

The only thing that doesn't work is the "Applet Menu" page

http://surendranath.tripod.com/Applets.html.

It would be a pitty if Mac users couldn't enjoy your wonderful applets !

I have looked at your site and seen the applets you are making and putting up for all to see and use. I think you are doing a great job and are to be commended for your work.

Since some of the applets that you have made might be useful to our students and we would like to make down loading convenient by having the applets made available on our University's WWW server, would you be interested in having us mirror your site?

Also some times it is advantageous to be able to customize the HTML shell that describes the applet. Would you find it acceptable if that was done. Of course your authorship would be acknowledged in the shell and this would be used for academic support of students only. No commercial usage will be made of the applets.

We have just received permission to be a mirror site of  Prof. Hwang's Virtual Physics Laboratory on the conditions described above and are now providing one of the many mirror locations that he has around the world. We could mirror your site in the same way.

Our home site is http://www.mta.ca/faculty/science/physics/
If you go to the following link( http://www.mta.ca/faculty/science/physics/useful_links.htm )
you will see a link to a mirror for NTNU applets at our University.

I have also placed a link to your applets on the same page.

Excellent, thoughtful little programs! Nice work.

By the way, how do people in India happen upon the name

"Reddy" is this the English spelling of a Hindi name?

Irish like it too. I think "Reddy" is a variation of

"Reidi" (West Meath) but this is speculation on my part.

This Reddy family is very fond of India.

Hope you enjoy teaching.

I was very pleased to see your Java applets on the web. My name is Rajesh Bharadwaj and I live in California(USA) and work for a high tech company. I was brought up in New Delhi and I hold an MS(Electronics engg) degree. I am wondering if you have any future plans to take these java applets to a new level so that the school kids could actually perform virtual experiments and collect data, write reports just like in a real Lab. I guess it is very difficult to do this if you are alone. Do you have access to other programmers in Hyderabad?

 

Whatever you are doing right now is very generous and educational for kids around the world. Please keep up the good work. Write to me. Give me some thoughts regarding what would you like to do with these applets, if you had the resources.

 

Thank you very much.

am a physics teacher in Brazil. I took a look at your applets and I think they are very good. I got impressed by the vector addition applet, as well as the angular momentum one (I must say that I haven't looked all of them yet, but I will in a near future).

I am working in a educational company called Positivo Informatica, a company which main purpose is to use the computer in education. The website of our company is www.educacional.com.br. Some areas of this site are open to general public, and some of them are restricted to our students (a username and a password are required). We would like to add your applets in our website including some physics concepts, which would be in portuguese. I'd like to ask information for placing the applets (or just linking them to your homepage) in our website.

Looking forward to hearing from you,

( You can see that at http://www2.ac-lille.fr/hazard-armentieres at Maths Profs)

I would like to give a problem about mechanism of Cardano ( un circle turning inside another circle which has double radium ) to illustrate the transformation of un circular movement in a linear movement.

It allows me to give calculations on angles and analytic geometry.

Do you now an applet which illustrate that mechanism? It would spare time for me.

I was looking for educational Java Applets... and I landed up on your

applets. Excellent work. I really was thrilled.

It is commendable effort. Having gone through the JEE and graduated from

IIT Delhi, I can understand the value of being able to visualise the

concepts in Physics. I am sure these applets will be a tremendous value

to interested students.

Good Work !!!

am a high school Physics teacher in San Diego, California with a

problem accessing your applets. The good news is your wave motion applet

is about the most useful tool on the entire internet for

teaching high school students basic concepts of wave phenomena.

Unfortunately I am going CRAZY trying to make it play back at school.

At home I am using a PC 400MHz Pentium based processor using a Netscape

Communicator 4.5 browser - and it works beautifully. But at school

neither my PC which formerly ran your applet nor my new G3 Powerbook

(MAC) will open the applet. I've attached a notice from another site

which explains (I think) what the problem is, but I don't know how to

fix it. I feel my students are missing an extremely valuable learning

aid if I cannot make your applet run. Do you have any suggestions??

Excellent material. I am a physics teacher in Burlington, Ontario, Canada.

I teach in an alternative setting where students come in when there schedule

permits. Many work and are upgrading their skills to enter college or

university programs. It is very difficult to do labs because of the limited

space and the number of students that I teach. I also teach Chemistry and

Mathematics. These applets have proven to valuable for teaching and review.

We do however have network problems that sometimes limit the students access

to the Internet. The question I have is, is it possible to download the

applets to a computer so that students could have access to them?

Thank you for you for your fine efforts in teaching.

I am delighted to see the applets - they are really "cool". I would have

to say that until a while ago, it would have been beyond my wildest dreams that I

could after all these years, get a visual refresher in Physics direct from

Hyderabad.

I mailed the links to my friends for them to check out and was about to

suggest that they be made available at jars.com. I checked and sure enough, they were

there! I checked out some other Physics related applets by Wang (from Lockheed

Martin?),Sergei and the guy from Colorado. They had some nice applets too. I

think Wang was the guy that made good use of java 3-D. After running these different

applets, my machine came to a crawl. I am led to believe that someone is not cleaning up resources. May be the dispose method is not being called on the Graphics object.

Everyone of my friends (including me) thought that the applets were very

well written. It only reinforces my observation that some of the best programmers have

a solid background in Math and Physics.

Only recently a friend of mine (who likes to worry), after watching a TV show on competition to enter college (it is actually a non issue compared to the Indian scene), was worried about whether he could send his kids to a decent college (btw, he is not yet married). I had told him that all he had to do was help establish a solid grounding in Math, teach the kid to communicate well and instill confidence. With these skills and confidence , the kid can pretty much carve out a career for himself/herself without too much regard to the college attended (or for that matter, course of study in college).

I am not saying that attending top schools does not give you the edge,

but sometimes, the extra money spent may not be worth it).

I will elaborate on why course of study may not be as important later.

Thanks again for letting me know about the links.

Thanks

I'd like to say that the applets that you put up at your site were

very interesting and informative. Though I'm only in high school, I'm

very interested in the first Chase applet.

Currently, I'm considering doing a project that simulates a missile

"chasing" it's target. I'd like to know how you were able to create the

applet so that the blue ball would chase the red ball. I tried to

understand the accompanying document but since I've only just begun

pre-calc, it didn't make much sense.

Could you by any chance give me a copy of the source code for the applet

(I'm proficient with Java programming)? And, is there any Internet site

that you would recommend to me for further study on physics of this

nature and Calculus? Thank you very much for your time and if you ever

need assistance in writing a Java applet, feel free to e-mail me.

I have a question about your two chase applets. At first I didnt

understand them - well, I havent understood them yet - untill one person

came up to me with bright eyes and said "beautifull" - he obviously

loves your applet. He told me that this is something about minimizing

integrals and at the university he was working all the student got

really excited about this subject and they did this in all kind of ways

(and dimensions).

Now, I havent quite understood the mathematical bases of these applets

and I would be even more gratefull, if you could tell me. Well obviously

... ehm ... Im thinking. No, please send me, if you have, some material

(equations etc - I dont know) about this subject. It doesnt matter if it

includes high mathematic since I am working with about 2000 physicsts

running around me, and I am sure that there will be at least ONE, who

could explain it to me.

Thank you again and again.

I went through each applets in your web sites. It is really a handy and

helpful teaching tools to help my students to visualize some of the

basic concepts in their physics course. I like them very much. Some of

the applets provide additional information and concept and some does

not. It will be perfect if you can cover some concept for each applets.

First, I want to compliment you on your beautiful animations.  You have done a superb job of exposition. 

 

A personal note:  When I was completing my senior year in high school in Texas in 1962, I attempted a display similar to your Kepler's Laws -2.  Computers were not personal nor available at the time, and there were only a handful of monochrome video displays in existence.  So what I did was take a slowly rotating display motor (the output was geared down) and use it to drive electrical wipers spaced at regular intervals around the circle.  I think I had to settle for four equal subdivisions of the orbital time unit.  This was all mechanical and very makeshift.  So I had four miniature neon lights which would blink in succession at equally spaced time intervals with a 50 percent duty cycle. 

 

Then I had to approximate eight equal areas for the radial sweep - four on and four off.  I used a surveyor's planimeter (analog) to measure the areas and it took a real long time to get it right. 

 

Next I put a circular piece of cardboard on the motor's axis and put two circular graphs on the cardboard: one for potential energy and one for kinetic energy.  I placed the motor and rotating graph behind the board of the display so the graph could show through a little slot which gave the effect of a linear, time-dependent gauge of both energies (whose sum was constant). 

 

It was clever enough to win first prize in Pure Physics at the Baylor Science Fair that year.  It was a lot of work, but I had a great sense of accomplishment.  Remember that space science had just turned into a very hot topic in 1958. 

 

------

 

So, getting back to your beautifully executed display, perhaps it might be enhanced if you added two time-dependent graphs of the kinetic and potential energies arranged so as to make it clear that their sum was constant. 

 

Please let me know what you think.  I'd really like to see how this looks. 

 

P.S.  I'm very envious of your work. 

Larry Niven has written a science fiction story titled "Infinite Series", if I remember correctly.  I believe it appears in an anthology of that name. 

 

I think you would find it extremely funny in light of your "Chase-2" applet.

MI name is Alfredo and I`m a physics teacher at a secondary school here in Spain. I visited the TIPTOP-Web in found your Applet about Kepler`s Laws very interesting. I would like to show it to my pupils, but we have no Internet connection at school. Can you tell me how to download it from the Web or could you please send me a copy of it via E-Mail.

I am writting to you to give my opinion on this site.I liked your

explanaition,you made it easy for me derstanding certain things in physics.

I have just one comment .........there are no pictures(drawing),I don't

know if it is my computer fault or something.If it was not, then I hope you

can find a solution for it.

Many thanks from us here in Jordan.

Keep it up.

i am a physics teacher looking for free java applets that i can use in my classes to help my students understand Physics concepts, and i came across your wonderful ones on Kepler's laws, transverse and longitudinal waves, and vector addition.

 

I was wondering if it'd be ok for you to send these to me, please...

 

thanks for your time

My name is Werner Krammer, I am a physics teacher in Austria. I like

your applets very much, and I would like to use them in school.

Unfortunately, I have no internet-connection in my classroom, so I would

need a download to run the applets offline. Maybe you can help me.

Thank you very much in advance,

Werner Krammer.

surrounding pages and index) to Swedish and make them available to my

physics students. I will, of course, be happy to include credits and

links to your original page and your mail address.

You asked for suggestions:

The javas function very well.

There is some layout on your pages that I think doesn't look the way you

intend, at least on some browsers and screen sizes:

index.html the main text on the page overlaps the brown area

sometimes

applets.html the boxes in the table are different sized. ( I

personally like a more compact layout- to make scrolling unnecessary,

but some people like a lot of space.)

If you would like any help redesigning the layout of yout HTML I would

be happy to help.

I'm a beginner in Java programing.

I'm working on my own (simple) Applet and on Your's page I found

an interesting Applet: Simple Harmonic Motion.

I would like to rotate a line. One end of line is fixed in the center of circle and

second one is turning around the circular line. On the second end of this line

is "integrated" little circle or bullet (see picture).

It's like Your model without "vectors" and colored angles.

Do You have any suggestions how to write a Java code for this example?

Or maybe You have any applets (with source) for similar problem that I'll

be learning on example.

 

I still have some questions:

- Is it possible to adjust speed for my applet?

- Is it possible to set (by user) different sizes of the circle?

- What is the best way to learn more about graphic objects in Java?

  (books, WWW sites, ...)

 

Thank You very much.

Best regards from Slovenia (SLO).

Congratulations for the efforts you have put, in preparing the physics

applets.It took me back by 3 decades of Physics khowledge..

Appreciating your efforts I wish you all the best.

I am a high school science teacher in Edmonton, Alberta, Canada.

My student teacher has discovered your web page with all of the really

great Physics Java applets. Unfortunately, I can't use them since I've

already covered those topics. Then next year, I'm taking a year off to

look after my 1 year old son. But when I return to the classroom,

(hoping I keep your web address) I'll use them as demonstrations for my

class.

I sure am envious! I would love to know JAVA!

I did check out your pages! Congratulations! I must say.

You did a very good job. I hope to see more of your java applets soon!

There is a lot of works need to be done recently.

Keep in touch!

hwang@phy03.phy.ntnu.edu.tw

The applets ran fine on a G3 Mac(blue tower), system 8.5, using IE 4.01

and the Apple MRJ 2.0. I also downloaded the latest MRJ, (Mac OS

Runtime for Java) (MRJ 2.1) and the applets also ran fine in that

environment.

Current versions of Netscape Communicator and Netscape Navigator (up to

4.5) use their own internal Java virtual machine and unlike Explorer you

have no choice. You have to run their virtual machine. This machine is

not JDK 1.1 compliant and the applets will not run under this environment.

Finally, thank you for sharing these applets. I will find them useful in

my classes.

I am a high school Physics teacher in Winnipeg, Canada. I came

across your applets on Transverse Waves and Longitudinal waves. I

thought they were excellent. I would like to have a copy of these two

applets for my classes. I was wondering if you might send me a copy by

email or tell me if there is a way of downloading them.

I look forward to hearing from you.

Thanks.

I looked at your home page "Surendranath's" I liked it allot. I am in eighth

grade, and I would like to do a sceince project on this, but it has to be an

experiment so I was wondering if you can tell me how I could experiment, with

this subject? If you will help me out I will include you in my Bibliagraphy

and give you credit for the work that you helped me with. Thankyou for your

time!
