Simulating Van Allen Particles
I added the ability to simulate a charged particle moving in the Earth's
magnetic field to my simulator. This lets you look at the motion of particles in the Van Allen Belts. The particles move fast. In the samples I created I have protons going nearly 1/3 the speed of light. They spiral around a North/South magnetic field line very quickly. A bit less quickly they are moving north and south (up and down). And much less quickly they are drifting East around the world. This is a very 3D motion, so my samples look first from the side (so you can see the North/South motion) and then from the top (so you can see circles and movement around Earth). Java applet is at http://spacetethers.com/spacetethers.html The samples are #85 to #88. -- Vince ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~ Vincent Cate Space Tether Enthusiast http://spacetethers.com/ Anguilla, East Caribbean http://offshore.ai/vince ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~ You have to take life as it happens, but you should try to make it happen the way you want to take it. - German Proverb |

Has it been down the last few months, or just the Java side??? |

Wasnt able to access your site with either IE 6.0 or Netscape 7.1 Other people tell me they have never been able to access your site with their browser either. Has it been down the last few months, or just the Java side??? I don't understand this yet. It works for many people every day. I can see from the logs that they have clicked on different samples because they download the classes for those samples. But you are not the first to have trouble either. If anyone can help with this I would appreciate it. I am on a small island in the Caribbean, so there is a chance there is some funny Internet problem. The nameservers for spacetethers.com are ns1.offshore.ai and ns2.offshore.ai. There have been times when a company had an internal "ai" domain in their DNS in such a way that people in that company could not get to my nameservers. Andrew Thompson is now also hosting the simulator so trying his site could avoid either of these problems: http://www.1point1c.org/st/st.jsp What exactly is the error that you get? Can you get to the home page http://spacetethers.com/ ? There is no Java there, so this could let us know if it is an Internet or Java problem. To test that your Java is working (could have been turned off), go to: http://thorin.adnc.com/~topquark/fun/applets.html and see if you can run any of those. There is like 150 KB to load, so it could take some time if you are on a dialup connection. The HTML I had for starting the applet was not the best it could be, and Andrew helped me get that fixed last week. So there may be some people who can get through now that could not. However, that did not take of you as that change was before I posted about simulating particles. If anyone who has trouble running my applet can give me feedback after trying any of the above I would really appreciate it. -- Vince |

Stereoscopic movies can be watched using an HMD (head-mounted display) helmet with LCD displays for each eye. Yes, it might be a little bit on the expensive side, but the effect must surely be worth experiencing. |
