Both quantities contain both direction and magnitude. They are
vectors.

Wrong.
Your table should read:
The Time Derivatives of Distance
Derivative Name times Mass
0th distance distance * mass
1st speed +/- |momentum|
2nd +/- |acceleration| +/- |Force|
3rd +/- |jerk| +/- |yank|
4th +/- |snap| +/- |tug|
5th +/- |crackle| +/- |snatch|
6th +/- |pop| +/- |shake|
or the title should be changed to "The Time Derivatives of
Displacement" and the 0th derivative changed "Displacement
Displacement * mass".
Based on this elementary error alone, we can assume that you and all
of your other works are equally fallacy riddled and transitively
wrong. It's a pitty Dirk is too corrupt to put you and your grade
school mistakes up on his website.

Dirk isn't so much corrupt as he is ignorant. Why else
do you suppose he has to go to such extremes to make his
life worth living?

From his postings, one gets the impression that Vajk is also bitter
and angry... never conveys the joy of learning physical insight. Just
one of the many cranky trolls infesting USENET.

He is very bitter and angry, and attacks those who have the good fortune of
experiencing the joy of learning.
You see, Vajk cannot convey the joy of learning physical insight because he
has failed in his attempts at learning.
He hangs out at rec.org.mensa sucking up to the posters there because it
makes him feel as if he is experiencing critical thinking first hand. That
is why he is a groupie... he cannot achieve things on his own, so he basks
in the reflected glory of others until his bitterness gets the better of
him, then he attacks.

Yup. A very verbose cranky troll who, like Peter Brown, George Hammond,
Pluto, and James Harris decide to cause people trouble by emailing whining
letters to the colleagues of those they envy.

Vajk is Uncle Al's bitch. Eunuch for rent! Get your capon! Scrape
off the brown and send Vajk around for another wipe. Vajk, Vajk, Vajk
- immaculate of literature citations, bereft of URLs, wholly innocent
of any retained formal instruction. Vajk is what Dartmouth University
could graduate if it abandoned its last pretense and thin facade of
academic qualification to fully embrace diversity and empowerment.
Imagine a party school filled with matriculants too stooopid to chug.

The distribution is primarily in the sci.* hierarchy. You post
bluster and nonsense when you attempt to post science, and the
rest of the time it is tourettish outbursts. Even Varney, as
twisted and childish as he is, abandoned your cause today.
Tell us once again how zero absorption means zero refractive

you're still mad at me for pointing that one out.

How about your infamous "diamond" project, Al? Where are the
diamonds you were supposed to have fabricated in 2001?
"Uncle Al has proposed a direct chemical synthesis of
single crystal diamond of arbitrary size, deposition
of 1 carat/cm^2-hr at ambient pressure. The first
run showed deficiencies in the chemical understanding,
which lead to Devil Solvent and Devil Solvent II in
the second run of experiments. That controlled the
chemistry - no graphite! - but there were material
engineering problems ("Alien,"when the little darling
bleeds). We have the third and final attempt budgeted
and scheduled for 2001.
On 31 Dec 2003 you wrote:
"We have a new blank reactor head in hand and it seals
to the old body. It gets drilled and welded in January,
we shake down for leaks in a dry run, then we go for it. "

While back in 2000 you had predicted:
"Uncle Al has reason to believe that gem diamond can be
kinetically chemically synthesized to arbitrarily large
size at a rate of one carat/cm^2-hr using a rather nasty
molten salt reaction medium christened Devil Solvent and
some awesomely clever reaction subtleties building on CVD
diamond and Brad Pate's insights. Two attempts to date
have underlined procedural problems (re "molecular acid"
in "Alien"). The Big Kahuna is scheduled for next year.
If I can find a gas-tight 1/2" coupling that uncouples

Al, your tourettish outbursts do nothing to compensate your
repetitive displays of ignorance in subjects in which you
present yourself as competent. I don't know how anyone else
feels about it but for me, quite frankly, they're boringly
repetitive nonsense little different from your blather about
how you're going to manufacture diamonds and how you're
going to get a Nobel for disproving the Equivalence Principle.
None of it is true even though you appear to believe every
word goes from your mind to God's mouth. I almost hate to
break it to you, but it just hasn't been working out that
way and chances are really good that it never will.

You stated the 1st time derivative of distance was velocity, and went
further to state that that distance * mass = mass. And then you say
"the table is correct as stated" Ha Ha Ha.

Velocity is a vector. Acceleration is a vector ... except in
curved spacetimes. The technical issues related to the latter
are properly the subject matter of differential geometry and
the study of manifolds.

I haven't heard any reports of public nastiness on the
part of Einstein. He certainly seemed innocuous shopping
on Nassau Street when I was a child. But that's one of
the many differencec between the competent and those who
are not.
