Still, to be exact, allow me to say that it's only near parabola for in-continousity.
I don't quite understand why you would say "near parabola". With the assumption that each "piece" of cable supports the weight of the bridge directly beneath it you get a function x^2. And this assumption is born out of engineering reality.
Hello, I'm Chris. I am a physicist finishing up my Ph.D. in chemical physics in Richmond, VA. I had taught both high school and college level physics for several years before going back to school. Now I'm a student once again (the only job I've held consistently.)
I founded the physics website ilovephysics.com, and we are coming up on our 2 year anniversary. Unfortunately, on our one year anniversary we lost everything due to a hacker, and have been slowly building back since. I discovered this forum through the punBB forum (the site that supports the script that runs both this site and mine.)
To support myself as I plug through courses and research, I founded two online business - J.C. Moore Guitars and KeyLiberty Marketing. I chronical my successes and failures on my business blog KeyLiberty.com.
I surfed on to this site from the punBB site. Looks good.
Have you thought about adding LaTeX support to the board? I have written a punBB mod called punLaTeX to do this using mimeTex. It allows for easy insertion of in-line equations. See more at the following URL:
It has really added to my forums usability. See an example here:
