To help me in understanding this procedure, I read the fifth chapter of THE DETERMINATION OF ORBITS by A. D. Dubyago, as translated from Russian into English by the RAND Corporation. Much of the nomenclature used in this exposition is patterned after Dubyago.

HELPFUL DESCRIPTIONS.
a : semimajor axis
For elliptical orbits, the semimajor axis is half the length of the longest line segment that can be drawn inside the ellipse. For hyperbolic orbits, the semimajor axis is the distance from the vertex to the nearest point on either branch.

I am desperately in need of help.
Some weeks ago, I inadvertently signed up to do a mathematics project, not realising that it really was about designing tutorials (preferably interactive) for students...
I'm having a heck of a time trying to define limits of motion for planar connection mechanisms. Does anyone know of a good tutorial so I can see how they're supposed to be assembled?
Is there a webpage with illustrations and well formed explanations on such as mol, g/mol, Mm etc etc? The Norwegian word for this part of chemistry is støkiometri. I believe it is something like stochiometry in english even though that sounds too odd.
I had a test on this today and I believe...
Just gave myself a quick tutorial on ASP.NET using C# and well damn its nice. PHP has been the programming language I have used for a few years to do web stuff and was wondering is this the time to switch to .NET or maybe its best to wait a year or two (before it blows everything away into...
Lineweaver(May 2003)--web's best cosmology tutorial
http://nedwww.ipac.caltech.edu/level5/March03/Lineweaver/Lineweaver_contents.html
I've been using Ned Wright's (UCLA astronomy dept) cosmology tutorial and FAQ a lot, but this new one is even better for some
things---more up to date...
The critical density of the universe is
rhocrit = (3c2H02)/8piG
which is the average energy density required for flatness.
Many people are put off by formulas this complicated and can't say just by looking at it what the density is in familiar terms---how many BTU per cubic yard or...
to keep things simple the units are c=G=hbar=k=1 and
all black holes are non-rotating uncharged.
I think everybody here probably has a qualitative notion of how the Hawking radiation arises from the event horizon of a black hole---there has been tons of pop-sci journalism about this. What...
