A publication of the Foresight Institute
Web
Enables Effective Nanotechnology Debate with
Scientific
American
by Lew Phelps
The exchange launched by Foresight Institute's response to Scientific
American's April 1996 news story, "Trends in
Nanotechnology," dramatically demonstrates how the World
Wide Web can enable effective debate on issues of science and
technology.
The outcome is a concrete example of the effect predicted in Eric
Drexler's 1987 article Hypertext
Publishing and the Evolution of Knowledge. Even at
this early stage of its development, the web is becoming a force
for higher-quality coverage of disputed topics. These higher
standards will surely influence paper publishing as well.
Update 24
reported how Scientific American staff writer Gary
Stix sought to debunk the scientific basis of nanotechnology
through a combination of ad hominem attack and appeal to
authority. Foresight responded with a comprehensive
annotation of that article written by computational
nanotechnologist Ralph Merkle
of Xerox Palo Alto Research Center. He spotlighted the article's
lack of technical support for its position, and invited Scientific
American editors to respond.
They finally did so, in a lengthy letter sent May 10 that
attempted to defend not only the original story but the
magazine's attempt to force Foresight Institute to remove all
quotations of the original article from Foresight's World Wide
Web site.
However, Scientific American's latest contribution to the
debate, an "Exhibit" on Nanotechnology placed on their
World Wide Web site, essentially concedes the field. Of seven web
site addresses (URLs) provided as links, six are supportive of
Foresight's point of view, including links to scientifically
notable institutions such as Caltech, IBM, and the Naval Research
Laboratory. The only negative evaluation of nanotechnology
included in the "Exhibit" is a link to the original Scientific
American story by Gary Stix, who did not author the
"Exhibit." The story, in turn, links to nothing that
supports it. The reason is obvious: no credible items published
on the World Wide Web support the original Scientific American
story.
Foresight Institute has published the May 10 responding letter
on its Web site -- again with extensive annotation to point out
the logical flaws, rhetorical tricks, and continued lack of
scientific content in both the reply and the original article.
The response from Scientific American Editor in Chief John
Rennie and staff writer Gary Stix ends: "In his conclusion
[to his rebuttal], Merkle writes, Scientific American
should stop evading the fundamental technical question: given the
currently accepted understanding of natural law, is
nanotechnology feasible or is it not?' It's hard for us to
believe anyone who has read the article would think we have
sidestepped that question, but we don't mind answering it again: sorry,
but far too many serious scientists say it is not." (Italics
added by Update for emphasis.)
Drexler commented, "Their response really exposed the
unintended message of their article - that despite all their
critical-sounding words, they have nothing to say against the
scientific underpinnings of nanotechnology, and can't point to
anyone credible who does. The article obscured this in a cloud of
opinions on other questions, and dragged in some pure
name-calling. But now, cornered by a direct challenge to back up
their position, they've responded with more dancing and dodging
-- not making arguments, not citing arguments, not even saying
what an argument on their side could possibly look like, or who
could deliver it, but instead saying that arguments of some sort
could be made, by someone, somewhere, someday. That's awfully
close to a declaration of intellectual bankruptcy.
"The Web let us show, for the first time, that even hostile
and well-connected critics like Scientific American can't
deliver real arguments against our case. Their public failure is
informative and valuable," he says.
As Drexler points out in his letter
to Scientific American, real science is not about who wins
an opinion poll or a favorable article, but rather "about
knowledge of the real world and its potentialities."
However, it is essential for Foresight Institute to pursue the
debate with vigor. For better or worse, Scientific American
has been seen as a "gatekeeper" of public opinion about
what's meaningful in science.
Foresight Institute salutes Scientific American for
correcting its position, and hopes to see the correction made in
the paper version of their magazine as well.
Foresight
Institute Sets 10th Anniversary Celebration
Achievements will be
Highlighted
by Lew Phelps
Foresight Institute reaches a major milestone this fall -- ten
years of exploring anticipated technologies and educating the
public about them.
To celebrate the occasion, Foresight is planning a major
festivity, scheduled for Saturday, October 19, in Palo Alto,
California.
"Save the date. We're expecting special guests -- people who
have played a significant role in the development of the growing
body of nanotechnology knowledge during the last decade,"
says Chris Peterson, Foresight Director. Full details will be
available in the next issue of Update, and sooner via the
Foresight World Wide Web site.
The ten-year celebration will focus on major achievements of
Foresight Institute in the last decade.
"Ten years ago the idea of nanotechnology -- of building
things by placing atoms in exactly the right places -- was not
widely known or understood," says Marvin
Minsky, MIT professor and member of the Foresight Institute
Board of Advisors. Today this still is often confused with making
things that are very small, which overlooks the special
advantages of making perfect copies. Finally, though, we are
seeing wide recognition that this may become the dominant
direction of the material technologies of the next century.
Researchers all around the globe are starting to pursue this
goal. In large measure this is because the Foresight Institute
has encouraged the exchange of cross-disciplinary ideas and
technologies, through the intense stimulations of its
communications, publications, and annual Nanotechnology
Conferences."
Futurist Peter
Schwartz has watched nanotechnology's growing policy-level
stature during the decade. "To those who have suggested that
nobody is thinking seriously about the economic and social
implications of highly advanced technologies, my reply is simple:
Read Engines of Creation
by Eric Drexler," Schwartz says. "Through his
publications and the work of Foresight Institute, Eric has done
more to make people think seriously about the future of science
than anyone I know." (Schwartz, who has advanced the process
of scenario planning through Global
Business Network, also serves on Foresight's Board of
Advisors.)
In parallel, Foresight Institute has been instrumental in
furthering the development of information exchange and evaluation
systems that will be needed to deal with the economic and social
change accompanying the realization of nanotechnology.
Foresight's Web
Enhancement Project is at the center of that effort, which
seeks to create an effective means to debate both the
technological issues and public policy issues arising from
nanotechnology.
"It's been a remarkable decade," says K. Eric Drexler,
Foresight Institute chairman. "When we started Foresight,
researchers only dreamed of manipulating individual atoms with a
scanning tunneling microscope. Artificial self-assembling
molecular systems were small and scarce. Some said protein
engineering was decades away, and we lacked the computational
power to do large-scale molecular modeling. A global hypertext
system like the Web was a great hope, but far from reality. We've
come a long way in a short time, and the pace is picking
up."
Commemoration of the organization's founding will include a
dinner party, planned to be limited to a maximum of 70 guests to
allow "intense interaction and discussion" and a
preceding cocktail reception, Peterson says. The dinner cost will
be $175 per person, with an additional $100 for the cocktail
reception. Discounts are available to Senior Associates.
Details of the event will be available later this summer on
Foresight's World Wide Web site, and in mailings to Foresight
Institute members and Senior Associates. Although the 10th
anniversary celebration will be held in conjunction with the annual meeting of
Foresight Senior Associates in Palo Alto, participation will
be open to anyone - until seating limits are reached.
NSF,
TopoMetrix and Silicon Graphics
Provide Grants To
Nanomanipulator Project
at UNC-Chapel Hill
The National Science Foundation,
Silicon Graphics, Inc., and TopoMetrix Corp. have
provided grants to the University of North Carolina (UNC) at
Chapel Hill's computer science department and physics and
astronomy department in support of the school's Nanomanipulator
Project. TopoMetrix designs and manufactures scanning probe
microscopes. Silicon Graphics makes computer workstations.
Dr. Russell M. Taylor II of UNC's computer science department
spoke on the Nanomanipulator Project at Foresight's 1993
Nanotechnology conference. The project is aimed at the combined
use of virtual reality and scanning probe microscope technology
to expand scientists' ability to manipulate matter at the
molecular level.
UNC received two grants: "Development of the
Nanomanipulator: A Real-Time Scanning Probe Microscope Interface
for Nanometer Science" is a two-year, $460,000 program with
funding from UNC, TopoMetrix, and Silicon Graphics. The other
grant, "Application of High-Performance Graphics
Supercomputers and Communication to Provide Improved Interfaces
to Scanning Probe Microscopes," is a five-year grant for
$2.3 million from the National Science Foundation.
The Nanomanipulator Project is a collaborative effort between the
molecular graphics and physics groups at UNC. It will provide a
radically improved interface to scanning probe microscopes, using
a graphics supercomputer and force-feedback device to provide the
illusion of a physical surface floating in front of the user. The
project was initiated by Dr. Warren Robinett in the computer
science department and Dr. R. Stanley Williams, then a professor
of chemistry at the University of California at Los Angeles.
The two-year grant provides funding to build a dedicated system
from off-the-shelf components. The five-year grant provides
funding to explore the use of next-generation graphics and
networking hardware, allowing visualization of multiple data sets
simultaneously with surface topography, and the use of
remote connections to microscopes.
For further information regarding the Nanomanipulator Project,

Nanomanipulator system to examine a section of fruit-fly
chromosome. The system combines an atomic force
microscope with a virtual reality interface. The system
operates over a scale difference of about a billion to
one. The user can directly control the lateral position
of the AFM tip; real-time force feedback indicating
surface height allows the user to feel the contours of
the object under study. (Image courtesy of the University
