Yes, Yes, Yes.  But there is something I want in return.  I want the
teacher to treat me like a paying customer (which parents and tax
payers are, at the elementary and secondary level).  For example, I want
them to be flexible and considerate about my schedule (Evening meetings
are _much_ better than day time meetings)

So have I.  I've _almost_ seen a reverse correlation.  Of course there have

Dear sirs,
  Let me suggest to your attention little advertising information.
We'll very pleasant for your notes and any related information.

   ASTRINGENT SUBSTANCE WITHOUT CLINKER FOR BUILDING PURPOSES

Possible substitute of portland cement is suggested.
The method of getting astringent substance without clinker on the
basis of silicate & alumosilicate rocks is worked out.

ASTRINGENT SUBSTANCE'S COMPOSITION:

Silicate or alumosilicate rock             72.5 - 90%
Composition correcting additive             8.0 - 15%
Activating additive                         3.0 - 13%
Other additives: plastificator,
air-involver etc.                           up to 1.0%

ASTRINGENT SUBSTANCE'S MAIN CHARACTERISTICS:

Specific surface                           200 - 500 m%/kg
Pour density                                 0.9 - 1.1 g/cub.sm
Water/astringent substance ratio              0.4 - 0.55
Activity                                   up to 40 - 50 MPa
Time needed for 75% firmness gain
under steaming                             6 - 12 hours
Thermoresistance                           1000 - 1200nC
Frost-resistance                           not less than 50 cycles

  Technology of astringent substance's witout clinker production
consists of dispergation of the initial silicate or alumosilicate
rock with correcting additive  up to 200 - 500 m%/kg  specific
surface. The value of 250 - 350 m%/kg for the specific surface
are more good. Other additives ( activating etc. ) are added with
water.
  Concrete mixture production, wares' moulding, thermo-humid pro-
cessing are utterly entered the technological scheme of the co-
rresponding productions on the basis of ordinary cements.
  The concretes on the basis of astringent substance without
clinker are needed less amounts of the astringent substance than
ordinary cements with the affinity of physico-chemical properties
of the astringent substance's basis & inert fillers.

  The group of elaborators of the astringent substance without
clinker is ready to conclude the agreement on the:
- exploration of the customer's raw material & possibility of
  its utilization as the astringent substance's basis;
- elaboration of the astringent substance's composition on the
  basis of customer's raw material;
- determination of the astringent substance's physico-chemical
  properties & conditions of the thermo-humid processing;
- elaboration of the concrete's mixture composition for blocks
  & bricks production;
- if it's necessary - to accomplish production of the experimental
  lot of blocks & bricks on the basis of customer's raw material
  & equipment.

Several things have happened to education here in the US:

We have ceased to treat the K-12 teachers as professionals that they
should be.  As a result, many of our teachers are not acting like
professionals--just doing what is necessary to get by.  The result is a
demoralized teaching cadre teaching our nation's children.  We need to
start by once again treating our children's educators like
professionals.  While they won't immediately live up to our expectations,
they will eventually respond in the direction of professionalism.

Universities are no longer as interested in a faculty member's ability to
teach as they are in a faculty member's 'grantsmanship' and ability to
do research.  In spite of what you often hear, (good researchers are good
teachers) I have observed low corrlation between research ability and
teaching ability.  This has led to university practice of hiring people
who care very much for their research but not very much for the courses
that they teach.  The students see this as indifference on the part of
the faculty member.  The result is an unenthusiastic, indifferent student
body, which feels alienated from his/her would be mentors.

American society must soon realize that if it wants an improved standard
of living, it must learn to produce more value in a shorter time.  This
'learning' to a large degree is going be done by our education system.  If
we want the good life--we'll all have to get a better education so that
we'll know how to get it.

I have a question about gas dynamics that people in that area may find
simple.  I hope.  I need an answer for a "back-of-the-envelope" calculation,
which I must try to solve as quickly as possible, so while I always 
appreciate being referred to textbooks, I will not be able to use them in
this case.  I therefore ask for answers of another sort.

I have a nozzle in which gases escape at known pressure and velocity.
It's the jet of a spacecraft, so the gases escape into a vacuum.  I
want a first approximation of the dynamic pressure of the escaped gases
at a known distance downstream of the nozzle, along the primary line of
action of the jet.  In other words, given p_0 and v_0, what's p_x if
x is known and along a straight line and the medium is a vacuum?  Assume
x is short enough that each molecule of gas is still moving in a straight
line, and that the profile of the escaping gases is conical.

Thanks in advance,

I am posting this message on behalf of Craig Potter as Comalco Research

Comalco Rolled products are investigating a strip cooling system on a
Loewy Aluminium strip mill.  I have been given the task to estimate the
heat transfer coefficient for coolant spray onto the moving Aluminium strip 
(<3mm thick, to be cooled from 130 to 50 C, moving at 500 m/min).  We intend
to use Norpar 15 (a exxon petroleum based coolant) as water will stain the
strip.  

I am looking for information on how to estimate the coefficient or if
any one has measured it what it could be (ballpark).  Has anyone used
Norpar 15 for spray cooling before?  Information on water spray cooling
and spray onto steel (such as in steel continuous casting) will be welcome
also as the spray systems are related(?).  I have read some interesting
papers on the subject, but no citations seem to have examinined spray
cooling onto moving Al strip in a production environment.

   Customers are people who buy something.  There is a well-established
industry of greeting cards.  All the firms in this business know that
their customer is the buyer of the card, not the recipient.  Why do
educators insist on believing that _their_ customers are the recipients,
not the buyers?

   Now you sound like a customer.  Quality Improvement programs _do_
have a lot to offer us, once we've correctly identified the customer.
Customers can learn to recognize and value quality, once the supplier
takes the time to listen to their needs and adjust the specifications
to fit those needs.

   Could we re-cast this discussion, starting with the customers' needs
and progressing into adjusting the specifications?

I think the problem is more related with the 'grantsmanship'. As a foreign
doctorate candidate with a lot of interest in research and in teaching
(When I return to my country.) I am always impressed with the requirements
for hiring professors in the USA. Goes like:"demonstrated capacity to
obtain independent funding and strong commitment to research"...
IMHO, the commitment to research should be a present in every
_university_ faculty member (That's why they were created in the first
place.), but the willingness to tranfer the knowledge obtained from
this research and from the previous education should be emphasized.
The true commitment to research is not the commitment to bring money
and prestige to your institution and yourself, but to advance human
knowledge. For that you should dedicate also to teach future generations.
I have found that professors dedicated to this kind of research often
make great teachers, as opposed to the ones dedicated to obtain grants.
The funding, fame and prestige shall come if you truly deserve them.

Just another frustrated teacher...

There was an issue of Biblical Archaeologist a few moths ago that

I don't remember if they covered olive oil presses, though.
I do remember that Biblical Archaeologist Review has had a number
of articles on olive presses.  Both magazines tend to have a Bibliography

Rural folk tend to change less than urban folk.  I think the contrast between
modern Egyptians and their ancestors who build the pyramids would be greatest
in the major cities.  Indeed, places like Cairo and Alexandria didn't even
exist then.  But if you lok at the models and pictures that the ancient 
Egyptians left and then visit a small town along the nile you'd be struck with
how little the people have changed since then.  
It might make a great research project to see how much has changed besides the
language and religion and how much has remained constant.  I remember once
having a cab driver in Cairo that was the spitting image of King Tut....

There has been one very significant change in the agriculture
of Egypt since ancient times.  The building of the various Nile
dams, especially the Aswan High Dam, has meant that the Nile
no longer floods.  In ancient times, the three-month inundation
controlled the whole pattern of life and work: the fields were
irrigated and fertilised (by the rich alluvial silt) free, with
no expenditure of effort.  There was a period in the year when
large numbers of people were available for work on large public
projects such as temples and, of course, the pyramids.  The
ancient Egyptians were well aware of the fact that the inundation
was the single most important feature in every-day life.  In the
20th C the soil needs to be irrigated and fertilised artificially
and cash crops, such as cotton and sugar-cane have to be grown to
raise the money for these needs.  Furthermore, the country is
trying to support a population some 20 times as large as ancient
times.  The romantic view of the timeless unchanging life of the
peasant is, I fear, just an urban myth.

I was watching a program on PBS that dealt with electromagnetism, and they
mentioned something about this.  I'll try to explain it as best I can.
The way I understood it, when the poles reverse, the electromagnetic field
that surrounds the Earth and protects it from the solar wind is shut off.
This allows more UV radiation to enter the atmosphere and this could effect
life on the planet.  When the reversal from north to south pole (or vice versa)
is complete, the field is switched back on.  I've heard of this being used
to explain mass extinctions (i.e. the dinosaurs) but I don't exactly know
how it ties in with archaeology.
