This demo shows: how to create point changes (more than one objects in the simulation),
 how to display electrostatic force, field lines and contours for electrostatic potential.

wow, i was stuck for a while before i realize the Firefox is not 100% compatible with http://www.phy.ntnu.edu.tw/ntnujava/simulationBuilder/


Used the ie and the another charge particle comes out Smiley

thanks prof for developing such a wonderful tool to bridge teachers with research.

i will develop applets using your tool.

btw, is there any issues with copyright if i make applets using your tools?

can the applets made with your tool belong to my employer ??

thanks!

I suspect the button is not working, from the name i was expecting the magnitude of the force to appear, but nothing happens.

in fact, when this button is checked, the other check box fail to show up

It appears the interface for checking existing records can't allow a listing of the applets made.

I am having trouble remember what i did in your builder, so if a list appears allows me to see the applets made already.

a Load / Save function will be very much appreciated

for your consideration Smiley


Fix the "send to email bug" yet ?  I can't wait to see the applet made Smiley

1. This is just a User Interface for Physlet. You can find the copyright from Wolfgang's Web site.
2. The interface was original created as part of editor tool for a content management web site (However, the web site is only shown in Chinese). So teacher can use this tool to create online content or even create online assessment ...etc.  I translated this tool into English version when I was invited to the U.S. for open source physics workshop several years ago. And I added it to this forum last year. Actually, you are the first one willing to try the English version (or the first one to report the problem). So I did not work on this for a long time. But most of the functions should work fine.
I did receive the file after I click 'send to my email' button. I just added the code which will show the email address and filename been sent. You can check for the message again. It also work fine in my firefox browser. (However, it is not working when I tried it at another computer- with different Jave installed, I do not know why?).
If there are people interested in using this tool, I will try to improve it according to suggestions received.

I just change the setting on our server.
Please try it again. Does it show correct email address?

I found the problem. It is because email deliver from our server to  yahoo.com.sg was treated as spam message. It is your email server which block the mail message and return back to our server.
May be you have asked our server sent too many messages to you in a short time, and your mail server  treat our message as spam  messages.

The following are message from yahoo.com.sg: I change your email address to XXX@yahoo.com.sg
---------------------------------------------------------------------------------------
This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

  XXX @yahoo.com.sg

now that you mention this, i have not been receiving the notification of replies in post and threads for a while from http://www.phy.ntnu.edu.tw/

maybe someone idiot using yahoo.com added emails from http://www.phy.ntnu.edu.tw/ as something bad and yahoo now blocks everything from http://www.phy.ntnu.edu.tw/

does it mean sense?

so i was hoping for a download button direct and simple solution to the problem faced currently.
for your consideration sir!!
thanks Cheesy

I just add another "download" button to download it directly.
Just unzip the file and double click html file.

By the way, I think our server was removed from SPAM list.
I hope mail server will be available for you now.

About list of the simulations you have create, I will try to add that later.
The builder was written several years ago. Now the javascript is much advanced.
So it is possible to create better interface.
If there are many users really interested in simulation builder, I will try to find time to re-write the interface.

under animator, there is a graph function, but not in the Efield

is it possible to draw a graph of Potential vs distance for a plane chosen example

i look a picture on the internet
this one is somewhat the closeness to what is taught in school



looking for to your updates Smiley

The physlet graph applet is an independent applet. You can use it with any other physlet applets.
I just add UI interface to combine animator applet and graph applet.
But I have never used graph applet with E/M field applet. I think it could be done.
But I think it will be much easier to build what you want with EJS.
So I would suggest you try to build it with EJS. If you have difficult with it, write down in detail what you want and I am willing to help.

Does anybody have a script to convert a wikipedia dump into an SDict source file? 

I know that there are premade .dct files available but Id like to rebuild my own so I can make them case and accent insensitive.

Thanks.
