As I heard it, the american pint is actually the "wine" pint, or 1/8 of the old "wine gallon" which was a measurement used a few centuries ago. As the british standardized the pint after the revolution it makes sense that the US would stick with the older version.
Program dog
parameter(n=101,m=101,luout=10)
parameter(big=10.0, small=1.0)
open(unit=luout,file='dogsballs')
xo = 0.0
zo = 0.0
radius = big
do i = 1 , 2
yo = float(i*2-3)
write(luout,*) n,m,1
call balls(luout,radius,xo,yo,zo,n,m)
enddo
end program dog
subroutine balls(luout,radius,xo,yo,zo,n,m)
pi = 3.14159
do i = 1 , n
theta = 2.0*pi*float(i-1)/float(n)
do j = 1 , m
phi = pi*float(j-1)/float(m)
x = xo + radius*cos(theta)*sin(phi)
y = yo + radius*sin(theta)*sin(phi)
z = zo + radius*cos(phi)
write(luout,*) x, y, z
enddo
enddo
end subroutine balls
Ah but rockets like to take off down wind. I tried launching a rocket into the wind once, and it became a very low-flying cruise missile which struck the house at the end of the field. Slightly downwind is the best option.
However as the balloon will be moving at the same speed as the wind, I don't see how a drogue will help in any way.
