You build many robots and send them up.  People on earth could
teleo-operate them just like people use bulldozers here on earth.  They
prospect around and build structures from the cement regiolith.  (the
regiolith is made of nearly the same stuff as cement)  The send up some
of the bare essentials such as pots and machining equipment, a few
chemicals and electric heaters.  The robots produce solar cells from the
silicon, and metals from the pots, which eventually will be powered by
electric power.  The robots produce more robots and more equipment and
more robots and more equipment and so on.  People could hop up there
occasionally, but the robots don't require any oxygen.  Eventually
enough machining and electronic and mining equipment could be built to
stop dedicating production to more machining and extracting equipment
for more robots and start dedicating production to aerospace.  Tough,
but you end up with a great lot more there then you initially launched
up.

Actually, Americium-241 is fissionable.  I think the bare critical mass is
about 100 kgs.  The greatest drawback of Am-241 is that it is hot,
thermally, because of the rapid radioactive decay.  This makes it hard to
make a storable bomb.

The result is 5 Ci not 50 because of the above.
See my post in sci.energy for my calculation
You're correct that we have to assume 100% Pu-239 to get
a well defined problem, as we both did.
We both point out correctly in our posts that Dennis has the
wrong scaling - activity is INVERSELY proportional to half-life.

I wonder if the patent office would issue the patent.  Isn't there
something nonspecific against assigning patents to devices which

oddly, not preventing psuedoscientific yabba like electronic divining

patent office employee by literally proving that it works, but since
it violates the "laws of physics", can't convince him that it works.

"But it does work."

There are several ways in which a black hole can form.
Currently, if two massive bodies (such as, say, two white dwarfs) were to 
merge as a result of a collision, they could go over the Chandreshekar 
Limit and collapse into a black hole.
In the early universe, when the density was very high, small regions that 
were slightly denser than average could have collapsed into primordial 
black holes, which could be very, very small.
As well, it may not be neccessary for a supernova to occur during the 
collapse of the core of a masive star to form a black hole.  If the core 
was massive enough, it could collapse into an effective black hole before 
the overlieing matter could impact and rebound, preventing the explosion 
from begining.  This would cause the entire star to rapidly implode 
without an explostion.

    Umm... I have that happen sometimes.  I have it happen when

More about this below.
On 13 Jan, I saw an interesting article in our local paper. Arthur R.
Butz, a professor at Northwestern University, has for decades vocally
denied that the Holocaust happened (the "extermination legend," he calls
it.)
But he has tenure, and Northwestern has tolerated his views all this
time. I personally think that's only proper -- academic freedom and all
that. His opinions are nonsense, IMHO, but there's a free speech issue.
But wait. There's more. Look what happened to an engineering instructor,
who was presumably untenured -- "When Sheldon Epstein, a Northwestern
engineering instructor outraged by Butz's 'hate, lies and libel,'
recently attacked Butz's views in class before a relatively small number
of students, he was fired. The reason: He had strayed from the class
curriculum." [*]
What worries me about tenure is not so much that incompetance and
stagnation are protected -- maybe I'd be willing to put up with that
in exchange for academic freedom -- but what about the effect tenure
has on non-tenured faculty, staff and students?
How often does the above scenario happen? The public hears only about
the outrageous abuses that make the news. How often do non-tenured
employees or students get shafted, either by an arrogant tenured
professor or by the misguided attempt to protect one? How often are
they afraid to speak out because they are automatically suspected of
the bitterness to which Bill alluded? How often are they afraid to
speak out because a tenured professor is viewed as virtually
invulnerable?
What are the hidden costs of tenure?

Hi Magnetically,
Hardware stores carry large, pretty powerful permanent magnets which
are used by contractors to pick up nails. Radio Shack may have some
also.
If you can't move Total flakes with the magnet, you can always stick
your little brother to the refrigerator with it.
No experiment is ever a failure.

No, I do know that, but I needed to know what was the actual mass that
goes missing (defects) during each of those reactions. That mass is
obviously changed to energy. The amount of energy formed was the number

From: EDS PHI Account Team
Date: Tue, 21 Jan 1997 18:45:38 GMT
I noticed in these posts nobody mentioned a tonic.  All "tonal" music is 
based on a tonic or keynote.  Basically, the composer establishes the 
tonic, move from the tonic, and then resolves the piece back to the tonic.
Simple melodies start on the tonic and then finish on the tonic.  This is 
a very simplified explanation of tonal music.  The tonic is something you 
have to feel or identify at the beginning of the piece.  It is the base or 
key note of the music.  When you move the tonic, this modulates the music 
to another key note or key.  
This will either make sense or seem incomprehensible.  This is because the 
tonic is something that is preceived. 
A final note:  this is the older definition of tonal music.  Modern 
theories have complicated matters unecessarily in my opinion.  The 
additions of the use of accidentals and different scales make the "tonic 
theory" of tonal music a little inadequate.

I thought we were using a "well-tempered" system.  When did we revert to 
the early baroque even tempered system.  Maybe I am misinterpreting the 
word equitempered.  The prefix "equi" should mean equal.  In the 
well-tempered system all notes are note equal.  Some notes have been 
adjusted to fit in the twelve tone system.  However, in a well-tempered 
system there would be no exact HCF for certain notes.  
This maybe a good mathematical defintion of tonal music.  However, music, 
like science, is a product of human perception.  Like, if a tree falls in 
the forest, does a bear take a crap in the woods or something.

In the hope of settling this issue, I crunched some numbers today and 
discovered a few things:
** Summary **
First, C&D; was wrong when they said the Viper would be ahead by more than 
260 ft at 130 mph.  What they should have said is that the Viper reaches 
130 mph in 260 ft less distance than the Porsche.  My analysis (which I'll 
explain later) shows that the Porsche needs 2,186 ft to reach 130 mph and 
the Viper needs 1,920 ft.  That's a difference of 266 ft in Viper's favor.
Second, between the time that the Viper finishes the QM (12.3 sec) and 
the time it reaches 130 mph (15.7 sec), it has closed the gap to the 
Porsche by a not-so-spectacular 20 feet (in fact, the Viper is alongside 
the Porsche). The Porsche is going 126 mph at this point.  
By the time the Porsche reaches 130 mph (17.1 sec) the Viper is going 
almost 135 mph, and has pulled out another 8 ft on the Porsche.
Third, even allowing for some calculation error, the Viper and Porsche 
are within horn-honking range (if not fender-tapping range) of each 
other at 130 mph.
** Method **
Using Microsoft Excel's Solver add-in, I fitted a curve to the speed vs 
time plot for each car.  For the Viper, I used the curve from C&D; 9/96.  
For the Porsche, I used the times from the 7/95 C&D;, filling in 
intermediate speeds based on the curve from the 6/95 Motor Trend.  BTW, 
the 20.5 sec 0-150 mph time in C&D; 7/95 is clearly wrong.  My curve-fit 
suggests it should be 25.0 sec.
The equation I fitted to the curves had the form:
Speed = (C1 * t^E1) + (C2 * t^E2) + (C3 * t^E3),
where C1..C3 are constant coefficients, and E1..E3 are exponents applied 
to the time variable.  After some frustration with setting up the solver, 
I fixed E1 = 0.40 and E2 = 0.75, then let the solver find the other 4 
unknowns by minimizing the sum of the squared errors. 
After the coefficients and exponent were found, I plotted distance vs 
speed for each car by integrating the above equation for speed.  As a 
reality check, I used the goal seek function to find the time required 
to cover 1320 feet (quarter mile).
** Results **
Each fitted speed curve matched the published curve within about 1 mph 
over the full speed range.
For the Viper: 
Speed(mph) = 430.86 t^0.71602 - 352.96 t^0.75 - 60.158 t^0.40
and 0-1320' in 12.3 at 116 mph
For the Porsche:
Speed(mph) = 357.75 t^0.72183 - 303.66 t^0.75 - 29.962 t^0.40
and 0-1320' in 12.3 sec at 113 mph
** Conclusions/Recommendations **
I am confident that this method generates a fitted curve that is at 
least as accurate as the published test data.  This method is readily 
available to anyone with access to later versions of MS Excel.  And 
IMHO, it's a helluva lot better than endless handwaving and questionable 
assumptions.  Try it and see.

This phenomenon is easily understood in the post-quantum physics of
back-activity from classical brain to quantum mind. Transpersonal
experiences happen when messages are exchanged between different
classical brains that share the same quantum mind i.e., wave function.
The Einstein-Podolsky-Rosen "spooky telepathic" objective nonlocal
form-dependent intensity-independent "active informational" (Bohm)
connection does become a communication channel in the presence of
back-activity. Eberhard's theorem which strictly forbids this does not
apply because it is only correct in the limit of zero back-activity.
Note, by "brain" I mean any classical material beable that is able to
back-act to its attached quantum pilot-wave. 
By "material", like Bohm, I include all "beables" not only classical
sources like electrons, protons at a moment in their trajectories etc,
but also their classical electroweak and strong gauge field
configurations on spacelike surfaces. 
God is the common wave function shared by all classical brains that
were, that are, and that will come. If we include the classical metric
of general relativity as a beable, which we must do for quantum gravity,
then we are forced to conclude that God's mind is the invisible grand
quantum pilot-wave which guides the evolution of the visible material
universe. Back-activity is the modern technical formulation of the myth
of God's Covenent with Abraham that gives us smaller homomorphic pieces
of the big wave function a limited degree of self-determination allowing
us to be morally responsible for our behavior. This answers David
Hodge's question at Tucson II. 
My theory of everything is the worst possible theory of every thing
except for every other now proposed in all the books by the pundits. :-)

My observation is that quantity of publications and research funding will always carry the
day when it comes to promotions etc.  Unfortunately no-one seems to dig a bit deeper about
the ethics issues abd whether or not the publication record and funding have been

I know many academics who work those hours as well.  Quite alot actually.  
In the department that I did my PhD nearly all the staff worked those hours.  They led by
example.  My point is for those who choose not to work their is no accountability.

I disagree.  Morally responsible, yes.  But the absetee academic or unethical (in terms of
co-authorship) academic can survive if not flourish.

In effect the real talent of a PI who chooses to flout the system is being able to
 identify and recruit good graduate students and postdocs.  The whole process become self 
propagating if the PI can gather enough surfs for his lab.  The PI need not turn up (other
than to sign purchase orders) yet will still be a co-author on many papers.

I was attempting to make a case that accountability would be better if tenure was abolished.  
By accountability I would include scrutiny of the contribution of PIs to papers.

Perhaps one of the causes is that many academics have never been OUT of the classroom.
If you are raised in a system in which unethical conduct, with respect to co-authorship,
is widespread it may be taken forgranted that that is the way things are.  
I think it will be very difficult to break the cycle.
I take your point about administrators.  Presumably bean counters look for methods of
evaluation and quantity of papers seems OK.  This doesn't excuse the unethical practises
though.
We both see it happening.

The size of the Coriolis force is equal to -2m(w x vr) where w is the
angular velocity of the Earth (a vector pointed along the rotational
axis), vr is the velocity of object in question in the rotating reference
system, and x represents the vector cross product.  The force will be a
maximum when the w and vr are at right angles.  This can happen at the poles,
if the motion of the object is horizontal, or at the equator, if the motion of
the object is vertical. 
If one is interested in the horizontal deflection of objects already moving
horizontal to the surface, then it is true that the force is a maximum
at the poles and a minimum at the equator.  To see this, imagine translating
the angular momentum vector for the Earth to the point in question on the
surface.  At the equator it lies tangent to the surface, so w x vr can only
cause a horizontal deflection if vr has a vertical component.  At the poles
w is radial, so any horizontal motion causes a maximum Coriolis deflection at
right angles. In between the poles and the equator, the horizontal deflection
due to the Coriolis force on horizontally moving objects will have a
sin(latitude) term which reduces it.

Subject: What is the global structure of the universe?
From: hedden@unix2.netaxs.com (Jerry Hedden)
Date: 22 Jan 1997 03:18:58 GMT
What is the nature (global structure) of the three-dimensional space (four-
dimensional space-time) of the universe?
One possibility, given by the Friedmann cosmology model, is that it is the
three-dimensional surface of a four-dimensional sphere.  The space-time
"interval" for this model is given by:
        ds^2 = - dt^2 +
                 S(t)^2 * d(chi)^2 +
                 S(t)^2 * sin(chi)^2 * d(theta)^2 +
                 S(t)^2 * sin(chi)^2 * sin(theta)^2 * d(phi)^2
  where t is in geometrized units of length (c=1),
        S(t) is the four-dimensional radius of the universe
                as a function of time
In this model, "the distance between galaxies" is given by chi * S(t).
This model has several feature that can be used to compare other models:
1.  Isotropic -- Any neighborhood in the three-dimensional space (for a given
time) looks the same any other.  One consequence of this feature is that it
has no boundary.  (Is the correct term for this 'unbounded'?)  If there were
a boundary, then some neighborhoods would be closer to it than others, and
as such the space would not be isotropic.
Cosmologically, this is important (at least in my mind) because space seems
to look everywhere the same (witness the cosmological background radiation),
and does not seem to possess any sort of boundary; some sort of "wall"
beyond which the universe does not exist.
2.  Finite -- at any particular time, the three-dimensional space forms the
closed surface of a four-dimensional sphere (e.g., x^2 + y^2 + z^2 + w^2 = 1).
I feel that this feature is EXTREMELY important cosmologically.  I
emphatically believe that the universe must be finite.  If it were not, for
example, then the big bang instantly created or simultaneously acted upon a
sturcture of infinite extent.  I do not believe that such a concept could be
physically manifested.  (I would, of course, welcome any comments on this.)
Further, if the universe started out finite, could it ever transition to
infinite in extent?  Can the answer to this be anything but no?
3.  Simply-connected -- It has the genus of zero.  (Forgive me if my
terminology is improper.  Any corrections would be appreciated.)  What I
mean by this is that there are no "holes" in the global structure such as
there would be with some three-dimensional analogue of a torus.
What is the cosmological "necessity" of this feature?  If the universe is
not simply-connected, then how would some complex connectivity be
accomplished? How would you form the hole?  And wouldn't the presense of the
hole create some sort of anisotropy as is does in the torus?  These
questions lead me to feel that simple-connectedness is a necessary feature
of the universe.
4.  Curvature -- In this case, the space has a constant positive curvature.
The curvature of a two-dimensional surface can be "determined" by measuring
the circumference of a circle about a point and comparing it to the radius of
the circle.
  Curvature     Circumference/     Examples
                   Radius
   Zero           = 2 * PI          Flat plane, or a straight cylinder
   Positive       < 2 * PI          Sphere, or the "outside" of a torus
   Negative       > 2 * PI          "Inside the hole" of a torus, or
                                      a hyperbolic paraboloid ("saddle-back"
                                      x^2/a^2 + y^2/b^2 = c*z)
The curvature of a three-dimensional surface (embedded in a four- or higher

surface by measuring the area of a sphere about a point and comparing it the

The Robertson-Walker cosmology model generalizes the Friedmann model, and
its space-time interval is given by:
        ds^2 = - dt^2 +
                 S(t)^2 * d(r)^2/(1-k*r^2) +
                 S(t)^2 * r^2 * d(theta)^2 +
                 S(t)^2 * r^2 * sin(theta)^2 * d(phi)^2
  where t is in geometrized units of length (c=1),
        S(t) is the four-dimensional radius of the universe as a
                function of time, and
        r is a pseudo-distance coordinate.
For a "closed universe", k = 1, and "the distance between galaxies" is
given by S(t) * arcsin(r).  For an "open universe", k = -1, and distance
is S(t) * arcsinh(r).  For a "flat universe", there can, technically, be
no expansion/contraction.  Therefore, k = 0, S(t) = 1, and r is distance.
For the closed universe case, again we have the solution of the three-
dimensional surface of a four-dimensional sphere which is isotropic, finite,
simply-connected and has positive curvature.
The flat universe would have zero curvature.  However, is there any sort of
flat space solution that is isotropic, finite, and simply-connected?  A
two-dimensional torus embedded in four-dimensional space would be given by
the equation set [x^2+y^2=1, z^2+w^2=1].  Analogously, a three-dimensional
torus could, I believe, be embedded in a six-dimensional space such that it
had zero curvature.  Such a construct would be finite, but would not be
simply-connected.
The open universe case possesses negative curvature.  The great burning
question in my mind is:  Is there an isotropic, finite, simply-connected
three-dimensional space solution for the open universe case?
If the answer to this question is no, then I do not see how we can seriously
consider the prospect of an open universe.

I would doubt much work has been done. A certain "tolerance" could probably
be built up but the (Newtonian) physics of the rest of it would probably
preclude it in any event. Falling down, dropping things on your foot, blood
pooling, walking, maintaining balance, etc.
In any event, if you come up with the energy source, I'm sure it could be
tested ;)

This is true.  However, since you carry no net charge, your electrical
potential *energy* is still zero.  An electrically neutral coin thrown
out of the cage has no electrical energy to release, and falls to the
ground exactly as if the cage was uncharged.  
A more intersting case is if your coin happens to carry a positive
charge Q.  Then it has a large electric  potential *energy* of V*Q,
where V is  the large electric potential of the faraday cage relative
to the ground.  The coin also has a small potential energy of
capacitance from the charge on the coin.  The large  potential energy
converts to kinetic energy (not electric)  as the coin enters the
electric field surrounding the cage and is repulsed by the like charge
of the cage.   On landing, the coin would release its small energy as
a small spark into the ground.

Nothing.  It is in asymptotically flat spacetime.
The point is, the Kerr solution represents a valid solution of the Einstein

the universe.  That makes general relativity non-Machian.

   Does it matter that Mancuso's results are at variance the vast bulk

   I agree that the fact that his results are different and are not
   accepted by the relevant research and academic communities does not
   necessarily indicate that they are incorrect - he could be that
   maverick who stands the science on its head.  Nonetheless, one should
   embrace his work cautiously.

Teaching an "incorrect idea" is no longer a real danger.  More likely
than not, a professor will be done in by an offhand remark. 
"Homosexuality is not normal." or comparisons of a woman's body to Jello
were reasons that faculty members jobs were threatened.  The point is
not whether the ideas were incorrect (in fact, they involved value
judgements or just plain bad judgement) but whether faculty have the
right to say anything at all- no matter how silly (unless the prof
happens to be black and insults Jews).  Of course, in industry, what one
says in such an offhand remark can be grounds for dismissal.   
As far as the veracity/utility argument is concerned, I would bet that
an assistant professor of mathematics who always tried to relate her
mathematics to something practical (no matter how abstruse) would
probably be denied tenure.  Mathematicians seem to love playing with
ideas that have little or no utility until some granting agency waves a
few bucks in front of their nose.
Oh boy - judges for life...  What evidence is there that judges who hide
behind a lifetime appointment are any better than those who must face
the voters from time to time?  Are their legal opinions of higher
quality?  Do they show up for work on time more often?  Do they work
harder?  Come to think of it, I would have loved to have had a chance to
vote against that idiot, Julius Hoffman - just one...

Your point about accountability is a good one.  The problem with highly
specialized curiosity motivated research (as opposed to goal directed
research) is that it can be pretty hard to judge wrt merit.  This may
lead to the quantity over quality problem you referred to.  To whom
should a PI be accountable? Students?  Other faculty?  Administrators? 
In an industrial research situation, the criteria often involve
commercial success.  Rarely would this be a consideration in a
university.  Perhaps, evaluations involving peer review from other
universities would be in order.  Perhaps teaching is the mission of the
department.  In that case it would seem that the same criteria being
used to support tenure decisions would be useful in periodic review
under a new system.  In any case, even with periodic review for the
purpose of making employment decisions, I would bet that very few
faculty members would be let go.
An implicit bargain has been struck in the tenure system that should be
acknowledged.  Faculty are paid less than similarly educated people in
industry (who, by the way, must submit themselves to periodic review). 
If we abolish the tenure system, we will wind up paying higher wages to
faculty who will only keep their positions only if they receive
acceptable evaluations.

Nah - you overstate the case.  The question is whether we will have
better universities if we abolish the tenure system in favor of a
lifetime merit system.  Perhaps we would if we could come up with the
right system.
