Amidst all the controversy about what nanotechnology is and isn’t, one thing that everyone seems to agree on is the visionary role of Richard Feynman as the founding father of the field, through his famous lecture, There’s plenty of room at the bottom. In a series of posts I made here a year or so ago (Re-reading Feynman Part 1, Part 2, Part 3), I looked again, with the benefit of hindsight, at what Feynman actually said in this lecture, in the light of the way nanoscience and technology has developed. But does the claim that this lecture launched nanotechnology stand up to critical scrutiny?
This question was considered in a fascinating article by Chris Toumey called Apostolic Succession (PDF file). The article, published last year in Caltech’s house science magazine (just as Feynman’s original lecture was), takes a cool look at the evidence that might underpin the claim that “Plenty of Room at the Bottom” really was the foundational text for nanotechnology. The first place to look is in citations – occasions when the article was cited by other writers. Perhaps surprisingly, Plenty of Room was cited just 7 times in the two decades of the 60’s and 70’s, and the annual citation rate didn’t get into double figures until 1992. Next, Toumey directly questioned leading figures from nanoscience on the degree to which they were influenced by the Feynman lecture. The answers – from scientists of the standing of Binnig, Rohrer, and Eigler, Mirkin and Whitesides – were overwhelmingly negative. The major influence of the Feynman lecture, Toumey concludes, has been through the mediation of Drexler, who has been a vocal champion of the paper since coming across it around 1980.
Toumey draws three conclusions from all this. As he puts it, “The theory of apostolic succession posited that first there was “Plenty of Room”; then there was much interest in it; and finally that caused the birth of nanotechnology. My analysis suggests something different: first there was “Plenty of Room”; then there was very little interest in it; meanwhile, there was the birth of nanotechnology, independent of it; and finally there was a retroactive interest in it. I believe we can credit much of the rediscovery to Drexler, who has passionately championed Feynman’s paper.” As for why such a retroactive interest appeared, Toumey makes the obvious point that attaching one’s vision to someone with the genius, vision and charisma of Feynman is an obvious temptation. Finally, though, Toumey asks “how selective is the process of enhancing one’s work by retroactively claiming the Feynman cachet? “ The point here, and it is an important one, is that, as I discussed in my re-readings of Feynman, this lecture talked about many things and it requires a very selective reading to claim that Feynman’s musings supported any single vision of nanotechnology.
Toumey (who is from the centre for nanoScience & Technology Studies at the University of South Carolina) is an anthropologist by training, so it’s perhaps appropriate that his final conclusion is expressed in rather anthropological terms: “We can speculate about why “Plenty of Room” was rediscovered. Perhaps it shows us that a new science needed an authoritative founding myth, and needed it quickly. If so, then pulling Feynman’s talk off the shelf was a smart move because it gave nanotech an early date of birth, it made nanotech coherent, and it connected nanotech to the Feynman cachet.”
My thanks to Peter Rodgers for bringing this article to my attention.
5 thoughts on “Was Feynman the founder of nanotechnology?”
Binnig for sure (honourable mention to Smalley). But nanotechnology (I prefer the phrase Nanorobotics) is still in its infancy. Ultimately the father may wind up being a researcher such as Zettl or someone else; whoever’s research winds up transforming industry. And if an exponential industrial capital base is facilitated by MNT, MNT researchers can lay claim to being the founders of post-industrial society.
I second Philip’s idea of calling Drexlerian Nanotech Nanorobotics!
What is the impact of the articles written by Feynman in the field of Physics?
Feynman made a massive contribution to the development of quantum field theory and quantum electrodynamics. Read his own book, QED: The strange theory of light and matter, if you are interested to learn more.
As documented at http://www.mrfm.org, the Toumey thesis itself is limited to the narrow definition given by Drexler. In the larger context of engineering and instrument development, of which Binnig and Eigler are part, and of which we find context for why Feynman was disliked by his theoretically-minded colleagues (but loved in the engineering laboratories) and why von Neumann was perhaps less-welcome among the blue-bloods at Princeton, the goal was clearly defined and has yet to be achieved…

Make the microscope one hundred

problems of biology would be
made very much easier.
