Re: #55 what is ...999999 + ....99999; new textbook; "Mathematical-Physics (p-adic primer) for students of age 6 onwards"

for the AP-adics to become a post-outlining,
publishable format, he'd have to be able
to comprehend his critics;
do you really think that he does, now?

sure, it's related to the comprehensability
of his own sub-book-length MSs --
a word is what I think it means,
whn I type it!... just like for every one, else.

Most of his published "books" are threads in these
newgroups.

"Most"? Have I missed something.

AP has redefined (like he re-defines a lot of things but uses the

thus:
although a bicycle is dynamically stable,
the tetrapod is stable when one wheel lifts
-- still "tripodal" on grounding. of course,
nothing is dynamically "stable"
without a lot of testing; apparently,
they tested that tricar on one kind of test, so....

Neither is a quad pod.

thus:
so, this seems to show that
there are 48 permutations of three objects (or,
What?), regarding Yaw, Pitch and Roll?...
anyway, I can only use tripolar coordinates,
as a matter of preference & ability!

I have a tracking system that gives me the rotation of an object in
the 3 euler angles in the order YPR. I have to do something with these
values and hand them to a system that visualizes refering objects by
applying their 3 stored angles in rotations ordered RPY.
Quite a few years ago I built a system named ARTIBODIES for
visualisation of articulated bodies and dynamical simulation of rotating
rigid bodies. Rotations and orientations are represented internally by
quaternions system-wide, and only when viewing and manipulating
rotations and orientations from a user interface Euler angles come
into play. So far the software design considerations.

I put the relevant representation conversion programs on my website at
http://www.xs4all.nl/~jemebius/Eulerang.zip, reachable from
http://www.xs4all.nl/~jemebius/Eea.htm<http://www.xs4all.nl/~jemebius/index.html.

Conversions run among representations by quaternions, by angle and axis,
by Euler angles following the avionics convention (YPR or ZYX), and by
Euler angles following the theoretical physics convention (ZYZ).
In my opinion the best you can do is to convert from YPR to quaternion and
subsequently from quaternion to your RPY Euler angles. I bet this yields
also the fastest code in the framework of need4speed. (RPY: another of
the 48 possible Euler angle conventions)


My software does not cover quaternion to RPY, but
I guess that the RPY and YPR conventions
differ no more than a reversal of 3D rotation matrix c.q. quaternion multip.
Perhaps my procedures provide some examples and some guidance in writing the
quaternion-to-RPY conversion yourself.

foremost, Harry Potter is a literary referant,
as well as simply an adumbration
of the imperialist "public school" a l'Oxford,
where Dame Maggie and Sir Tony got their policy,
Hey, George, let's you and Saddam fight!)...
of course, by exposure to geometry and
the higher arithmetic, they'll have
had some exposure to letteracy (sik),
as well as linguistic expression
of the other elements of *mathematics*

trivium, the "3 Rs" of a literate slave).
