Well Thomas, I'm no economist, but from your statements I see 
*you* aren't either (despite your rightious knocking of Nick).  
With the rash, unsubstantiated statements flying around here, however,
I guess I have as much right to talk out of my field as you do.  
...but I won't.  What I will do, for the sake of those wanting
pro and con information from *professional* economists, is recommend
they pick up this week's edition of TIME magazine.  

TIME interviewed a group of the nation's leading economists (gee, I didn't
see Thomas' name...) and asked them to comment on various aspects of
both Bush's and Clinton's economic plan.  As a sneak preview, *none*
of these professionals expressed the right-wing paranoia so beautifully
displayed by Thomas.  They did have some doubts about both Clinton's and
Bush's planned policies, however there was a slight majority consensus
that Clinton's would result in better long term growth.  Of course the
objective reader may choose to ignore the comments of talented professionals
and accept the statements of a single armchair quarterback (read "Thomas").
Weirder things have happened...

6.         DESCRIPTION 

CLOSED CAPTIONED FOR THE HEARING IMPAIRED

The award-winning FUTURES, hosted by famed-teacher Jaime 
Escalante and his actual students, captures his innovative 
teaching style (profiled in "STAND AND DELIVER").  
Escalante's tremendous success is based on the fact that 
students are usually better motivated when they can connect 
what they are studying now to what they will be doing in the 
future.  FUTURES is about how math relates to the working 
world -- to careers and jobs.  It is designed to motivate 
students to study math by showing them the many ways math is 
used, and the opportunities and life-styles available to 
those who have good math skills.         

7.  PROGRAM TITLES

101: AGRICULTURE -- The world is faced with growing 
populations and decreasing land availability.  But research 
and technology may pave the way to meeting the increasing 
food needs of the earth's population, using ecologically 
sound methods. Students will see innovations in agricultural-
engineering, aqua-culture, hydroponics and farming in space, 
as introduced by specialists--all of whom use mathematics to 
"feed the future."
Learning Objectives:
* To introduce students to trends and people in modern 
agriculture.
* To demonstrate practical applications of math in 
agriculture.

102: AIRCRAFT DESIGN -- One of mankind's greatest 
fascinations is with flying: from mythological Icarus making 
wings of wax to the human powered Gossamer Albatross flying 
over the English Channel, to the Voyager plane 
circumnavigating the earth, non-stop, on one tankful of fuel.  
Students will see that only through an understanding of math 
could engineers design crafts that would stay in the air.  
Former Blue Angel, Navy Lieutenant Commander Donnie Cochran 
joins Escalante and his class and talks about the preparation 
needed for a career in jet aviation.  Students will see how 
some of the world's most unique aircraft are designed.
Learning Objectives:
* To familiarize students with many areas of aircraft design.
* To give students some practical math applications in the 
area of flight, e.g. ratios.

103: ARCHITECTURE AND STRUCTURAL ENGINEERING -- The great 
skylines of American cities are monuments to mathematics.  
Structures, from skyscrapers to rollercoasters, are only 
feasible because of mathematics in practice.  Pritzker Prize 
award-winning architect Frank Gehry joins Escalante in this 
program.  Viewers will go for a wild ride on Viper, Magic 
Mountain's newest, most daring rollercoaster, and meet 
Viper's designers, then go to New York City and meet Ysrael 
Seinuk, one of America's preeminent structural
engineers, and Cooper Union's student engineers.
Learning Objectives:
* To familiarize students with architectural and structural 
engineering, past, present and future.
* To show students basic math applications in the work place 
of architects and structural engineers, e.g. geometric 
shapes.

104: AUTOMOTIVE DESIGN -- The automobile is part of most 
students' fantasy life and remains America's largest single 
industry.  Indy 500 champion Danny Sullivan joins 
Escalante and demonstrates the math concept of velocity, 
leading to an exploration of the world of auto design and 

engineering at General Motors Advanced Concept Center and Art 
Center College of Design.  World famous race car designer 
Nigel Bennett, encourages students to "get all the math and 
physics you can" if you want to become involved in automotive 
design.
Learning Objectives:
* To introduce students to the automotive design industry.
* To show students practical examples of mathematics in 
designing and racing cars, e.g. velocity, distance/time.

105: CARTOGRAPHY -- Mapping is no longer limited to making a 
record of the terrain of a region.  The rapidly growing 
population of the earth has made necessary detailed studies 
of the physical and social environment, ranging from 
pollution and food production to energy resources.  
Cartographers are also engaged in mapping the moon and other 
planets.  The major math applications cartographers use are 
scale,ratios, points, and coordinates.  The most important 
tool used in cartography is the computer.  Actor Edward James 
Olmos joins Escalante and Carlos Hagen-Lautrup, head of 
UCLA's Bruman (map) Library as this segment explores state-
of-the-art mapping processes.
Learning Objectives:
* To familiarize students with the field of cartography.
* To show students math applications in many varied 
cartographical areas of math, e.g. coordinates.

106: FASHION -- Most students relate to fashion and style, 
but how many realize the importance of math in the creation, 
manufacturing and marketing of clothing? According to 
numerous fashion industry professionals, "all too few!" This 
segment will follow fashion, from designer's drafting tables, 
to manufacturing, buying and merchandising--demonstrating 
"the mathematics of fashion." Actor Kadeem Hardison and top 
model Cindy Crawford join Escalante and the students in 
discovering the realities behind designing and marketing 
"math" team jackets.
Learning Objectives:
* To introduce a behind-the-scenes look at a career in 
fashion.
* To show through real interviews with specialists that math 
is not only important it is  essential to success.  Math 
applications include costing.

107: WATER-ENGINEERING -- It could be argued that water is 
the most important element in our lives, but one which we 
only stop to consider when there is too much (storms, 
flooding) or when there is not enough (drought).  From coast 
to coast, mathematics is vital to the management of water.  
Film director James Cameron (The Abyss) joins Escalante to 
explore the water supply from New York to California where 
literally billions of gallons of water are needed daily.
Learning Objectives:
* To introduce students to the world of water control, 
conservation and use.
* To show students practical math applications in the field 
of hydro-engineering, e.g.  volume and rates of flow.

108: OPTICS -- Optics is the study of light and vision.  In 
the future lasers and fiber optics will revolutionize 
medicine, media and communications.  Students will see inside 
AT&T Bell Laboratories, Lasermedia, and the University of 
Arizona, Tucson, Optical Sciences Center where students meet 
world famous astronomer Roger Angel. They'll see PacTel's 
futuristic video telephone Video Window. They will also meet 
world renowned photojournalist Mary Ellen Mark and 
photographer J.P. Morgan.
Learning Objectives:
* To introduce students to the world of optics.
* To show students numerous math applications in the optics 
field, e.g. fractions.

109: PUTTING MAN IN SPACE -- From that day in 1969 when man 
first walked on the moon, the world has marveled at America's 
dominance in space exploration.  We are now committed to 
manning the first space station -- a remarkable 
accomplishment of engineering and imagination.  Astronaut 
Bonnie Dunbar joins Escalante to take students to Johnson 
Space Center in Houston to demonstrate how math is 
fundamental to the engineering that shapes our ability to 
operate in outer space.  Students will get an inside look at 
NASA's Mission Control, Weightless Environment Training 
Facility, Flight Simulation and Robotics Laboratory. Learning 
Objectives:
* To take students behind the scene of our nation's space 
program in Houston.
* To introduce students to the various applications of math 
and computers in the space program, e.g. balance and 
equilibrium.

110: SOUND ENGINEERING -- Students love music, but it's a 
long way from a songwriter's idea to listening to a hit tune 
at home on your CD. The world of modern sound technology is 
designed and built using the language of mathematics.  
Students will travel behind the scenes to a rock concert, 
recording studio, the world famous Hollywood Bowl, and the 
film industry.  Students will meet Dr. Elizabeth Cohen, sound 
acoustician for the Hollywood Bowl; Tom Holman, creator of 
THX theater alignment; Dr. Amar Bose, Professor of Electrical 
Engineering and Computer Sciences at MIT, and president and 
founder of the Bose Corporation.
Learning Objectives:
* To introduce students to many areas of sound and the 
diverse jobs available.
* To show students the need for "numeracy" in the field of 
sound, e.g. sound waves, digital sound.

111: STATISTICS -- Everybody wants predictions about the 
future. Statistics is the only way we know to confidently 
project what could happen based on past results. The 
increasing role of statistics in the census, in the music 
industry, in marketing, politics, and sports will be 
highlighted.  Actor Arnold Schwarzenegger, Chairman of 
President Bush's Council on Physical Fitness visits the 
classroom to discuss the role of statistics in determining 
the physical fitness of our nation's youth.
Learning Objectives:
* To show students that statistics (and statisticians) are 
everywhere, affecting our lives.
* To introduce students to various math concepts, e.g. 
sampling and projections.

112: SPORTS PERFORMANCE -- From the crack of the bat and the 
curve of the ball, to sprinters, skateboarders and skiers, 
athletic performance is being shaped by technological 
innovation. Students will see mathematics being used at Santa 
Cruz Skateboards, Nike, Dodger Stadium, Specialized Bicycles 
and other venues. Kareem Abdul-Jabbar and Jackie Joyner-
Kersee join Escalante to explore the impact mathematics is 
having on world class athletics.
Learning Objectives:
* To introduce students to the people and designers behind 
sports.
* To show math applications in designing equipment for 
athletics, e.g., parabola.

Subject: Miscellaneous responses to hypersonic questions
Newsgroups: sci.space

"Why not use launch HALO from the <Aurora, or your favorite balck program>?"
  
    That's fairly simple.  We can't.  For all intents and purposes, top secret 
stuff might as well not exist.  As long as various hardware stays classified, 
it can't be used for a testbed, and we can't really even konw for sure if it 
would be suited to the task.  I'm all for declassifying much of this stuff, 
since I think it's mainly to keep it out of financial scrutiny, but until
that happens, you can't buy an Aurora.

   NOTE:  The hypersonic release test that someone eluded to does not refer
to secret aircraft.  This was a test of a drone (the M-12?) being released 
from the SR-71.  Now that I think about it, maybe M-12 refers to the SR-71
modified for the drone.  Anyway, it's not secret stuff. While it may be
potentially dangerous, the ones who know way it can be done.

My informationa says the A-2 was "damaged to an irreperable degree," but I

You'd need to do more that "dust off" thirty year old experimental 
hardware to get me into it.  I'd be very skeptical about flying X-15's.
Besides, they aren't really suited to the task.

Top speed was 4,519 mph (7,273 kph) acheived by William Knight.  I don't 
know what the structural limits were, but it sounds like that was more
of a problem on landings than flight :-)

Fission drive has been fully tested and flight qualified. It was abandoned
shortly thereafter. NERVA was to supplant the S III stage on the saturn V 
for Apollo twenty, upping the delivered payload to the moon to 98 tons,
from the baseline Saturn V's 48 tons. Not bad, not bad. There were 
movies of the test of the Nerva at the World Space Congress.  It was a

I haven't seen the EE Times article, but it sounds very much like
something I read about elsewhere--sorry, don't remember where, but 
it was recent.

The article I read mentioned very high conversion efficiency for
current -> photons.  I don't recall that it said anything about
conversion the other way.  But there didn't seem to be anything
fundamentally irreversable about the conversion process, so the 97%
figure that you cite doesn't seem out of the question.  However..

The catch is that the 97% figure would only apply to point source
illumination at the single frequency for which the device was
physically configured.  You might be able to achieve a record solar 
conversion efficiency by creating a spectrum of solar images, falling 
onto a graded strip of these devices.  You might even come close to 
the 80% that is the approximate thermodynamic limit.  But it wouldn't 
be cheap, or practical for large scale use.

The real promise of these devices would appear to be for power
beaming.  I gather that the emitted light is similar to a laser beam, 
in that it can be perfectly collimated.  If the conversion efficiency
is really as high as 97% in both directions, it would make a fine way
to power electric rockets on deep space probes.

They are well understood, for the most part.  They are not low, as
you yourself note the high rate of dry holes -- sometimest whole fields
end up dry.  There are also less-well understood risks, such as the
political climate in Russia.  (Or in the U.S.!)

This doesn't stop them when the product they are after is useful,
people will be it, and they'll make money.  It should stop
them when there is little desirable product or service, like the projects
you are promoting.

Were comsats at that point in 1962, when AT&T had invested over $300
million ($92) of its own money, and Hughes a big chunk of its own
money, before NASA stepped in and claimed credit and Congress forced
AT&T out of the business?  One wonders why comsats reached that
point so quickly, while we've spent $100's of billions on astronaut
projects and space stations that never have.  It must be "short-term
thinking" to spend money wisely and do something useful.

>Nowhere has anyone yet hit a gusher in space that justifies
>a lot of dry holes.

In fact, we are learning about the Jupiter-family comets, which will
be the oilfields of the 21st century, fueling the cargo rockets
plying between the planets major and minor.  It's just that
NASA and most space fandom is living back in the 1960's,
when socialism was the utopia and the space program the epitomy of 
the glories of socialism, and who gave a damn if it was useful.
Too many still live under the delusion that NASA is providing a 
rational vision for space development.  It should be commerce, or at 
least an applications and business orientation, providing the leadership, 
not a washed-up "vision" of yesteryear that has already squandered 
$100's of billions from our treasury.

And indeed, we have $100's of billions worth of failures, and practically
no commercial successes, to show for this risk-taking.  How is this
supposed to be good?

This is nonsense.  VC's regularly invest in biotech companies where 
revenue doesn't start coming in until 10-15 years after the investment,
if the drug doesn't fail completely, eg to get FDA approval.

Check out your chemistry books. platinum is one of the best if not the best
chemical catalyst in existence. We use a little in every Catalytic converter
on every car in the first world.  A Brinks truck comes into a factory near
Huntsville every week with a shipment of platinum for the catalytic converters
made here.  Platinum is used in many industrial processes. (Some smart 
researcher here should give us a breakdown). It would be wonderful if the
price of platinum would drop by a factor of 10. Then there would only be
100 billion dollars worth on the asteriod BUT consumption would go way up and
some industrial processes would become more efficient due to the new cost
effectiveness of using the lower cost patinum.  Therefore demand would 
increase greatly, while lowering the cost of our overall industrial process.
If this were an American enterprise, this could put our basic industries
that rely on platinum based catalytic processes to become more cost 
competitive on a world basis, which would help ease our balance of payments
burden and begin to bring terrestrial wealth back into this nation. Not a 
bad deal actually.

What about gold? Well if the price dropped by a factor of ten, there would 
only be nine billion dollars worth of gold. Well that puts gold at a price
in the $30-$40 dollar range. This would bring much more demand for gold,
especially in electronics packaging which is where the majority of gold
is used today.  This lowering of cost, if an American enterprise would make
our electronics industry more competitive on a global basis, therefore 
bringing more wealth into this nation, creating jobs for the educated, and
providing money for needed social services as well as for the bread and
circuses crowd in Congress.  Not a bad deal actually.

I haven't mentioned the Nickel and Iron that makes up the vast majority of
the asteroid.  There is probably a couple of trillion tons of smelter grade
nickel/iron (read steel) available on that one asteriod.  What would this
do? It would effectively end all iron importation to the United States, 
(We mine very little these days ourselves). This would help in our
balance of payments.  Also, the vast quantity of material could be used
in places where it is not cost effective to do so today, such as in the
primary structures of bridges and buildings. Stainless steel, which this
material basically is, would last five hundred years between needed replacement
on bridges in the Northeastern US and Europe, vastly lowering maintance
and replacement costs for our interstates. (Remember that a recent estimate
placed this cost in the 200 billion dollar range in the next 20 years).
This of course would free up billions to be used for bread and circuses as
well as to buy back our country from the Japanese and other foreigners. Not
a bad deal for ONE asteroid.

Then after all of these goodies, a much larger fraction of the American
people would have the wealth to buy gold plated bathroom fixtures.

Not a bad deal really

That was the premier episode of "Frontiers of Flight", which will run
weekly on Discovery at 8CST on Saturdays.  Each show will focus on a plane
in the NASM collection.

The X-15 show was very good.  I especially enjoyed Scott Crossfield's
comments.  After one early flight failure, Scott was describing how the
rocket engine exploded and blew off part of the rear of the X-15.  This
forced an immedieate landing, too soon to dump all of the fuel.  The heavy
landing caused the X-15 to break just behind the cockpit.  To sum things
up, Scott said that they had two failures on that flight.  First, the engine
blew up, and second, the aircraft broke in two.

Early X-15 flights were unpowered glide tests with the X-15 being dropped
from the B-52 at about 30,000 feet.  Total glide time was just over 3 minutes.
Scott commented that his `check out flight', the time he was allotted to
learn to fly and land the X-15, lasted all of 3 minutes 37 seconds.

An orgainzation of glider fans once sent Scott Crossfield a polished brick.
Scott said that he did not realize it at the time, but that he apparently
set a record for the shortest time for a glider to descend from 30,000 feet
to landing.  To the best of his knowlege, he still holds this record today.

Frontiers of Flight showed a few seconds of footage of the X-15 engine
explosion on the static test stand at Edwards.  Crossfield said that he had
a slightly ominous feeling while he was climbing into the airplane and
everyone else was heading for the block house bunkers.  About the explosion,
he said it was the largest noise he ever heard in his life.  One engineer
at North American calculated that Crossfield experienced a force of 150 G's
during the explosion.
