An expression that gives the average obliquity of the ecliptic is:
23d 26' 21.45'' - 46.815'' *T - 0.0006'' *T^2 + 0.00181*T^3

This would be the same formula that calculates the length of the
bannister on a spiral staircase. That calculation I found last year in
a staircase problem from the web. Ill look again tonight and if no
one has responded, will send the formulae tomorrow.

Does anyone know how to figure the length of a spiral line, given only the
width between the lines and the diameter. or the radii of the circle
I think this is underspecified; what spiral? Do you have a formula
for the curve?

Hello All,
Jorge sends us the equation for determining the mean obliquity
of the ecliptic as given in Astronomical Algorithms, J Meeus, [21.2]. A
more accurate equation is given in [21.3]. Also, to determine the true
obliquity, the nutation in obliquity must be incorporated. The
