I don't have any data sheets at hand, but as far as I remember, Kodak's
black-and-white infrared film (available in 35mm and 4"x5" sheets) is
sensitized to 900 nm, and will therefore be suitable for imaging at
880 nm. My personal choice, however, would be a normal silicon detector.
Most black-and-white video cameras' sensitivity extends to ~950 nm. I
have personally used normal ccd cameras for imaging in the 750 to 850 nm
range, with no problems whatsoever. Some video cameras have cut-off
filters to eliminte IR sensitivity, but in most cases these filters
can be removed (or the camera can be ordered without the filter). Take 
a look at the data sheets for b/w industrial video cameras (Pulnix for
example), and see if they'll fit your needs.

NANOTECHNOLOGY
Research and Perspectives

edited by BC Crandall and James Lewis

Advances in physics, molecular biology, and computer science 
are converging on the capacity to control, with  molecular 
precision, the structure and function of matter. These twenty 
original contributions provide the first broad-based 
multidisciplinary definition and examination of the 
revolutionary new discipline of molecular engineering, or 
nanotechnology. They address both the promise as well as the 
economic, environmental, and cultural challenges of this 
emerging atomic-scale technology.
  Leaders in their field describe current technologies that 
feed into nanotechnology -- atomic imaging and positioning, 
protein engineering, and the de novo design and synthesis of 
self-assembling molecular structures. They present 
development strategies for coordinating recent work in 
chemistry, biotechnology, and scanning-probe microscopy in 
order to successfully design and engineer molecular systems. 
They also explore advances in molecular and quantum 
electronics as well as reversible computational systems and 
the fundamental physical constraints on computation. 
Additional chapters discuss research efforts in Japan and 
present the prospects of nanotechnology as seen from the 
perspective of a microtechnologist.
  The final section looks at the implications of success, 
including the prospects of enormous computational power and 
the radical consequences of molecular mechanical systems in 
the fields of medicine and life extension.

Subject: Discussion group on Drexler's new book on the WELL
Date: 16 Dec 92 05:05:31 GMT


	
	The WELL is a computer conferencing system where people post
responses to topics, and can read what others have posted. It is
divided into some 200 conferences [plus private conferences such as
the one I will describe].

	There is a private conference on the WELL devoted to the study
of Drexler's new book "Nanosystems". If you are on the WELL, simply
send me email [my userid on the WELL is solovay] and I will add you to
the user list for this conference. The emphasis of the group are the
technical issues raised by Drexler's book, rather than the social
implications and future prospects of Nanotech.

	If you are not a member of the WELL, you can join by
telnetting to well.sf.ca.us; the internet coordinates of the well are
192.132.30.2 

	the following is the blurb you will see if you pick the
newuser account [the one used to register]:

The WELL is a computer teleconferencing system running on a SEQUENT
S27 computer located in Sausalito, California.

The WELL offers users access to approximately 200 WELL conferences,
to the UNIX operating system, to USENET,UUCP mail and the Internet.

The basic cost of the WELL is a $15/month service charge plus a 
$2.00/hour usage fee.  Your first 5 hours of usage @ $2.00/hour
are free, so you can get to know the system, though you may want
to wait until you get the manual to make the best use of this time.

	End of blurb.

	I personally enjoy the WELL very much. There are conferences
on every topic from soup to nuts, including politics, science, sex,
and a conference for writers to compare notes on their experiences.
There are a lot of very bright people on the WELL. The politics is
left of center, and there are more hackers and humanists than pure
science types. Among other "celebrities", William Calvin [the author
of "The Cerbral Symphony"] is an active participant. All in all, it's
a good place.

	One last thing--if you do decide to join the WELL, I'd be
grateful if you would mention my name at the appropriate place in the
signup form; and I'd be very pleased if this posting leads to new
active participants in the "nanosystems" conference.

	I want to mention to sci.nanotech two study groups that will be
working through Drexler's new book "Nanosystems".

	The first is a face-to-face meeting that meets every two
weeks, so far on the Stanford Campus. I will include the first announcement
for this group in this posting. In a second posting, I will describe a
private conference on the WELL [a computer conferencing system]
devoted to discusssing the "Nanosystems" book.

	There will be a second meeting of this discussion group on
Decmber 14th whose topic will be all of Chapters 1 through 3. It will
also be in Tressider Union on the second floor. I'm not sure if it is
also in the Birch room; I will post when I know.

	Probably the best thing if you are interested in getting
further information about future meetings is to write Ted Kaehler

Subject: Controlled Release (was: To Spread The Meme)
Date: 18 Dec 92 01:32:27 GMT

An old thread I know.  I hope I have taken enough time to think it out:-) .
Thus far no one has said that we should not Spread The Meme.  It's really a
question of how and when.

At the end of a Tom McKendree post dated 1 Dec 92 JoSH says:
[My own take on this subject is that nanotechnology is already quite
a popular subject, comparatively.  It's more important at this point
to increase the depth of interest, rather than the breadth.  And that
requires substance, not PR.  The best thing we can do for nanotechnology
right now is to do nanotechnology!
--JoSH]

At some point it will be neccessary for us to seize the memetic high
ground.  When?  As Richard P. Feynman once said:  "I don't know."  
T-Shirts for responsible grad students are fine as long as I get them too. 
I am sure that the National Air and Space Museum,  The National Space
Society, The San Francisco Exploratorium, and the Impressions Five science
museum in Lansing, MI would be interested.  I think the full-color ring
structure in a recent _Science News_ is especially striking.

Another responsible channel might be the online community. 
Alt.binaries.pictures.misc can hold postings in Graphic Interchange Format
(GIF) as well as JPEG.  Postscript and GRASP (an IBM format) are also
possiblities.  The QuickTime video format for the Macintosh computer is not
only digital but *non-linear*.  I once saw a QuickTime file which let you
adjust the X and Y rotations for a robotic arm.

Meme theory may be subject to something like the "Gresham's Law" of
economics--Bad money drives out good.  Possibly, Virtual Reality has
received such a bad rap by having one Timothy Leary as a self-appointed
spokesman.  IMHO Dr. Leary is basicly a nice guy but a pretty poor
spokesman.  The fuse here is short.  Terrence McKenna (a so-called "Leary
of the 90's) is quoted in _Unbounding the Future_ and nanotechnology
receives a mention in McKenna's latest _Archaic Revival_.  Eventually Leary
will hear of nanotech, and then we must be prepared to seize the memetic
high ground.  

Some things must be done immediatly.  I would like to spread the Bioarchive
Project meme so that we can preserve DNA samples in liquid Nitrogen *while
they are still around*.  John Perry Barlow is no flake (he has written for
the _Communications of the ACM_ and _NeXTWorld_).  I hope that he could use
his connection to the Grateful Dead to get the message out to the
rainforest crowd.  One Deadhead friend heard my description and said: "You
mean like _Jurrasic Park_?"  

Just for the record I did not suggest that nanotechnology be part of the
plot or text of a rock video--just another background image amidst a welter
of others.  Possibly response:  "What are those weird looking things back
there?"  Of course Peter Gabriel is a part of Global Business Network....

	Considering that many of these horrors were encouraged and carried
out by the Catholic church and the other churches that subsequently split
off from it, I find it hard to just attribute it to individuals.  After
all, these are the institutions that claim to represent G-d on Earth.

	No, but if the NIH and every other major scientific institution
in the country endoresed it, and encouraged attacks on any who didn't
believe in the Phlogiston Theory, I would be a lot more skeptical about
scientists in general.

	Another possibility occurs to me. In the original post, the 
person mentioned noticing this phenomenon in the mirror.

	Now, if the mirror is ANGLED, this can produce an apparent slope,
depending on the angle of the mirror. (As a kid, I used to LOVE those
mirrors that shoe stores had on the floor; they were tilted so that
they appeared to reflect me standing on a floor which was at a 70 degree
incline!).

	Once this impression has been given, looking back over one's 
shoulder through the window might not correct it -- especially since the
angle and movement of the vehicle confuse our senses to some extent 
anyway.

Yawn.. not this again.  Look, if someone claims to be a xian and acts

that action is un-xian?  ANother xian.  But what if the first xian

Look, it's simple.  If an xian performs an act and says its an xian

    But so-called "womens' groups" are using crap like this to "uncover"
    (or more likely, simply invent) heinous crimes committed by men,
    crimes so hideous that they were "repressed". Showing exactly why
    this IS crap is absolutely relevant to discussions of feminism.
