I just dragged out my old National Linear Book.  The LM 78XX (XX=05, 06 ...)
even has a xhematic diagram.  Between the input and output is an NPN
transistor and a 0.3 ohm resistor.  Thre rest of the circuit sure looks
linear to me - a differential pair between output and a zenered reference
that drives the output through an emitter follower etc. etc.  The spec
sheets shows the output imnpedance rising above 2000 Hz - could this
be the source of the noise you see?

Of course some clever manufacturer could have come up with an equivalent
part that is a switching regulator as long as it meets the 78XX specs.

Ahem.   Gentlemen, this argument is disintegrating into a set of
personal flames.  Could we get this back to a discussion of some
semi-technical topics, or into a set of space policy options (with
supporting technical/economic rationales), please?

   And by the way -- I also have a MBA (concentrations in Finance
and Operations, with a strength in Strategy).  And I also have 'bent
metal' for spacecraft recently, as well as pushing paperwork as
'chief systems engineer' on a NASA contract -- which is currently on
schedule and under cost.  Which one I won't discuss -- but it's in
excess of $10e6 and is scheduled for flight in the next year.  I've
also led "product development teams" which have designed and
produced other pieces of space hardware - on cost and schedule for
the DoD, NASA and commercial entities.
   Look -- a MBA doesn't make you a papershuffler.  Nor does it make
you a good 'manager'.  What it does is give you more tools to
develop a better understanding of the business and how what you are
doing fits better into the overall program and business perspective.
Some of the tools taught in MBA programs can be used effectively in
aerospace development and production programs.  Others can't easily
be applied (My class in "Multi-National Working Capital Management",
for example, even though the topic is fascinating....).  Some of the
tools can be directly applied (For example, the class I took in
"Operations Analysis and Management Techniques").
    Similarly, a Masters in aerospace engineering doesn't make you
an expert on spacecraft design, nor does a Masters in political
science make you an expert politician.  In my opinion no academic
education, by itself, makes you an 'expert' in any field.  (I will
admit there may be exceptions to this rule, particularly if the
field is purely academic -- such as "History of the Romance
Languages"). The academic educations provide tools and frameworks of
organization of problems which can be applied to resolve real-world
problems.
   IMHO to be proven an expert, one has to demonstrate that
skill by accomplishments in the field.
   And I should add, you don't need an academic education to become
"an expert", if you are willing to learn from your mistakes and from
others.  And you don't need to be an expert to have an opinion, or
to be able to converse and argue intelligibly about a topic.
   However, there is a lot of "flame" in this forum at the moment.
That flame is not contributing to the rational discussion of the
topics being brought forward, an exploration of the differences of
opinion or the sources of those differences of opinion, nor
contributing to providing data for others on the net to learn from
or establish their own opinions.
  What we've got is a bunch of opinions being promulgated as "sez
me" "sez you" and semi-personal attacks (which are uncalled for at
any time).

   Please, can we do better than this?

Subject: Aurora spotted ?

 I found in the popularization review "Science et Vie Junior", special
issue "La vie extra-terrestre", January 1993, the description of an
"encounter" which makes me think of Aurora:

 "Over the open sea: on September 2, 1990, a Boeing-727 of Air France,
flight Strasbourg-Algiers, crosses the Mediterranean. On the radar on
board, a mysterious echo, resembling nothing known, follows the same
road as the plane. Speed: about 7,800 km/h ? The radar has been checked,
it was functioning normally. What could happen is still unknown."
(end of quotation)

 I have my own idea about that. 7,800 km/h = 4,850 m.p.h = about Mach 7
(like Aurora). Direction: Strasbourg => Algiers (between N => S and
NNE => SSW), not very different from Scotland => Libya (NNW => SSE).
Aurora is said to have a base in Scotland (maybe Machrihanish, Kintyre
peninsula), and the US like very much to spy on Libya. Who disagrees ?

Subject: Brontides

Thanks to Mr. McElwaine (yes !) I found back a reference I was looking
for. That's about the so-called (if my memory is good) "brontides".
Here is the interesting (for me) excerpt from McElwaine's posting:

>      deployed beginning in the Fall of 1977.  In late 1977 and
>      early 1978, there was a strange rash of giant AIR BOOMS along
>      the East Coast of the U.S and elsewhere.  The AIR BOOMS were

>      than aircraft sonic booms.

I thought these booms happened in the mid 80s, therefore I could not
find back any reference. Now I have found:
"East Coast Mystery Booms: A Scientific Suspense Tale", by Deborah
Shapley, Science, Vol. 199, 31 March 1978.
Of course the explanation in Science is not at all McElwaine's
theory (which unfortunately I have already forgotten, but which, IMO,
will soon be posted again). Deborah Shapley reports three hypotheses:

1. Thomas Gold, professor of astronomy at Cornell, and Gordon MacDonald,
a geophysicist, suggested explosions of leaked, airborne methane, coming
from tectonic activity of the earth. Other scientists were skeptical.

2. The NRL (Naval Research Laboratory) suspected military aircraft
flying at around 35,000 feet for brief periods of supersonic flight.
But skeptics said these aircraft were doing that for about 15 years.

3. Jeremy Stone, FAS (Federation of American Scientists) director,
and Richard Garwin, an IBM scientist, thought the Concorde was the
cause of most of these booms. Turns south of Nova Scotia would have
caused the booms reported there. Acceleration of Concorde off the
coast of England would have sent shock waves which would have been bended
down to earth by the thermosphere (altitude 100 miles) and could have
hit the New Jersey or the Charleston area.

But the Concorde flights have continued after 1978, and it seems
that there were no more booms. Has anybody on this list heard of
a more convincing explanation ?

Regarding my own theory, which was that it was a precursor or a first
prototype of Aurora, it seems not very good. The mid-80s would have
been OK, but 1977-1978 is probably too early ... but who knows ?

It seems that the 1991-1992 "airquakes" over California were not like
those giant booms - these airquakes were described as short rumbles making
the ground lurch. But maybe the boom over the Netherlands on August 19,
1992, has something to do with these "brontides" ?

Depew's superiors and Julf are, in each case, the person most immediately
empowered to take care of the perceived problem.  You won't find an exact
parallel between the two situations, but this is a reasonable one.

I think the annihilation model is unnecessarily pessimistic. I suspect that
the only civilisations that could survive to the point of space mastery
would be those that have overcome many war-like tendencies.
The rest would probably self-destruct with their world-killer toys.

Monsters in far away lands are a common, and inaccurate, theme in human history.
Compare maps produced in the middle ages with popular modern science fiction.
'Here be dragons' is simply replaced with 'here be vogons'.

Also, I have difficulty with item II (and with the SETI program).
How narrow we are to search for other civilisations using radio-type
technology. My guess is that other civilisations have surpassed such primitive
technology. ( Unless, of course, they retained it in order to broadcast
repeats of 'Here Comes ycuL'! )
I'm glad that there is a commitment to SETI, but would hope that other
technologies are considered in the program. Does anyone know ?

Subject: Lunar ice transport
Newsgroups: sci.space

    The ideas suggested for cable cars, railroads and pipelines are
interesting (I especially like the pipeline), but they all involve a
*substantial* amount of civil engineering.  The main advantage of the mule
train approach is that there is minimal route preparation.  You simply
survey the route (with as many detours as necessary) and use 'dozers &
dynamite where it's unavoidable.
    Of course, it could easily be the case that the terrain is much
too rough for any overland route to be feasable.
    Having said that, I do like the pipeline.  While the start-up
costs are greater, the high potential throughput and low operating costs
are attractive.
    To overcome the problem of freezing at night, the pipeline could
be buried in the regolith (an excellent insulator).  Does anyone know
what the mean temperature of regolith is at, say, 2 meters ?  The
cost of ditch digging would have to be balanced against the increased
capacity.
    Another potential problem solved by burying the pipeline is micro
meteorite punctures.  What is the flux of micro meteoites at the lunar
surface ?   Would it be a long term problem for an unburied pipeline ?
    Also, a pipeline would require some measure of refinement at
the poles, as you do *not* want to be pumping muddy, gritty water.  To
take it a step further, you could perform the electrolosis at the pole
and pump the H2 and O2 to the equator seperately, though that would be
outside the scope of the design project.

    A separate consideration is the useful lifetime of the project
(be it mule train, pipeline, or ice-flinger.)  If the ice deposits will be
exhausted in 30 years, a scheme with high start-up costs would be
undesirable.  Were the students given an expected life span or are they
just assuming an indefinite period ?

Sorry if this has been asked before, but in the FAQ list I could not
find an easy answer to my problem.

If one could "take away" the earth in an instant (remove the influence
of the earth on the moon), what would happen to the moon's orbit around
the sun?

Would the moon eventually plunge into the sun, stay at the same orbital
distance as now or escape from the sun? Or, would it get closer to the sun
and find a stable orbit there?

Please send comments or answers directly to my userid, since I am not

Subject: NASA Paperwork

This message might be WAY off base, but ..

Okay, so there's lots of paperwork, and reasons for it.

But lately it seems like when something on a spacecraft is stuck,
a mechanical problem, it was caused by a mallet whack, or the use
of the wrong fastener, or something similarly trivial.  Trivial
until a multi-zillion-dollar vehicle has a mechanical failure.

Let's say it was a whack with a mallet to get something to fit.
After the deployment problem, this mallet whack is traced.

Was this mallet whack noted in the paperwork ?

If so .. Who signed off on it ?  Wasn't there a procedure to
require an assessment of the possible effect of a mallet whack ?
Or did some assembly tech just do it and not have to tell anyone ?

If the mallet whack wasn't in the paperwork .. Why not ?

In either case, what then is the point of all the paperwork,
if it can't stop simple mechanical problems caused during
spacecraft assembly ?

It is important to distinguish between the paperwork being in order
(we *have* document XYZ123), and the *contents* of the paperwork
being in order (document XYZ123 maps to reality). I do not deny that
it is necessary for any project more ambitious than an afternoon
spent in one's shed to store (often boring) information in a more
reliable and accessable form than the human brain. The trouble is
that it is easy for management to become focused on paperwork rather
than the real goals of the project.

For an example of a pathological case of this see Richard Feynman's
description of how NASA managers started with what they felt was a
politically acceptable rate of launch errors (100000 to 1) and then
fitted in numbers, running the engineering logic backwards, until
they had inputs that produced the desired outputs. ("Fantastic Figures",
page 177 of "What Do *You* Care What Other People Think.")

In many ways the whole Process debate in software engineering is
based on the (in my opinion wholly false) premise that one can find
a series of rules and regulations for manipulating paperwork that will
be completely self-encompassing, such that one *only* need take care of
the paperwork, by following the process, and well engineered products
will drop out as if by magic, with no intellectual effort, consideration
of design compromise, or effort by experienced programmers striving for
elegance. Indeed, one can run the whole thing with kids and pay them
peanuts for their trouble.

Paperwork exists only to serve the original engineering goals, not the
other way around. In order for the paperwork to remain honest, it must
be subject to continuous engineering scrutiny. We do not know how to
systematise this scrutiny, and have to fall back on the diligence of
experienced engineers when we apply it at all. When management
(especially non-technical management) is motivated to track and operate
through paperwork because the paperwork *is* easy to systemise, and the
paperwork universe can be freed of much of the mess of the real world,
it is difficult to find anyone to give the engineers a mandate to provide
scrutiny with a brief that amounts to little more than "keep your eyes
open and your sense of trouble keen," and back them up.

I'll offer two further aspects of this view of the engineering vs.
paperwork dichotomy. Firstly, the paperwork model stresses the
depersonalisation of the engineering process. You are supposed to be
able to mow down engineers as in the final scenes of "Zulu", and more
will pop up and take over their paperwork. The paperwork also means
that the structure and activities of the team can grow to the point
where no one individual can comprehend even all the parts that they
directly interface to. The engineering model identifies individuals
motivated and able to have creative insights and organises their
work such that they can see what is going on, so that their judgement
and knowledge is applicable.

Secondly, while it does nothing whatsoever to assist with the positive
side of a project, the creative judgement I referred to above, the
paperwork model does wonders when it comes to identifying individuals
who can be deemed to be "at fault" after a mishap. The engineering model
is to do with getting it right, the paperwork model is to do with
getting it wrong. I have heard it argued that if everyone is busy covering
their backsides then no mistakes will be made, but this is quite fallacious.
Nothing would ever get done at all if people didn't take risks every day.

My own opinions, not those of clients past of present.

Thanks for reading, Alan

Amazing!!!!!  NASA needs to get one smart guy who can understand to
within 10 or 20% what is needed to make a station work.  Put him/her
in charge and make their word law.  No paper bibles, just the authority
or this chief engineer.  And if something made by a contractor doesn't
work, there should be penalties.  Not like Morton-Thiokol...

I like you spelling of communitee.  Kind of cross between community
and committee.  There should be a word with that meaning :-)
