5 times the ships mass in Anti matter and 15 times in matter. Err.

Oh I'm sorry, I just thought you were listing the equations in a small page
and linking to a program that was incompatable with me anyway. Since I
can't follow half your equation I thought I was out of the loop.
'Page' is aukward term for web docs. I keep thinking of about a printed
sheet of pager worth of text.
Netscape did seem to have any problems. All images/equations seemed to
How on earth do you pronounce "Yrev Tsaf"? Does that mean anything special?
The fine print with purple charcters is a little hard to read but not a big
Some of the tables would be more helpfull if related to a physcal thing.
For example where you list fusion energy to specific impluse. Fusion
energy is listed in what I think are mass conversion ratios. (100, 200,
300, etc.) Which would be more help full if you had a table showing what
fusion reactions generate those amounts. Or more clearly explained the
This is a big issue to me, since I'm trying to consider things from an
engineer point. So I usually need exaust velocity/specific impulse, or
power in watts per kilo/pound of fuel, or something.
Mentioning which units your using in the equations would be a big help too
(kilos, gram, mols - watts, ergs, Joules, etc.)
Some parts I couldn't follow. For example.
Results of the calculations:
Mass at time t
: ( 8.1) ( 8.2)
Power needed at time t
: (14.1) (14.2)
Total Energy needed
: (12.1) (12.2)
Use (xx.1) when condition (3.3) is true, otherwise use (xx.2)
I have no idea what your saying here. In general I had a hard time
following the arangement of the equations and the numbering scheme.
at one point:
Energy mass needed:
Mass left over after "extracting" the energy:
The following formulas determine if and how much mass should be dumped:
This condition can be rewritten:
f is (Total mass)/(mass that can be converted to energy)
f is always bigger than or equal to 1
For matter & anti-matter mixture f=1 and L[t]=0
For De+He > He ...... fusion (3.5E14 J/kg)
f=257 and L[t]=256k[t]-j[t]
I couldn't fiqure out how to work back to the equations. Possibly going
through the use of the equations a step at a time or something, might help.
I tend to get lost in the equation section. Which can be frustrating since
it seems to be covering info I want to get.
