“A nothing will serve just as well as a something about which nothing could be said”*…

Metaphysical debates in quantum physics don’t get at “truth,” physicist and mathematician Timothy Andersen argues; they’re nothing but a form of ritual activity and culture. After a thoughtful intellectual history of both quantum mechanics and Wittgenstein’s thought, he concludes…

If Wittgenstein were alive today, he might have couched his arguments in the vocabulary of cultural anthropology. For this shared grammar and these language games, in his view, form part of much larger ritualistic mechanisms that connect human activity with human knowledge, as deeply as DNA connects to human biology. It is also a perfect example of how evolution works by using pre-existing mechanisms to generate new behaviors.

The conclusion from all of this is that interpretation and representation in language and mathematics are little different than the supernatural explanations of ancient religions. Trying to resolve the debate between Bohr and Einstein is like trying to answer the Zen kōan about whether the tree falling in the forest makes a sound if no one can hear it. One cannot say definitely yes or no, because all human language must connect to human activity. And all human language and activity are ritual, signifying meaning by their interconnectedness. To ask what the wavefunction means without specifying an activity – and experiment – to extract that meaning is, therefore, as sensible as asking about the sound of the falling tree. It is nonsense.

As a scientist and mathematician, Wittgenstein has challenged my own tendency to seek out interpretations of phenomena that have no scientific value – and to see such explanations as nothing more than narratives. He taught that all that philosophy can do is remind us of what is evidently true. It’s evidently true that the wavefunction has a multiverse interpretation, but one must assume the multiverse first, since it cannot be measured. So the interpretation is a tautology, not a discovery.

I have humbled myself to the fact that we can’t justify clinging to one interpretation of reality over another. In place of my early enthusiastic Platonism, I have come to think of the world not as one filled with sharply defined truths, but rather as a place containing myriad possibilities – each of which, like the possibilities within the wavefunction itself, can be simultaneously true. Likewise, mathematics and its surrounding language don’t represent reality so much as serve as a trusty tool for helping people to navigate the world. They are of human origin and for human purposes.

To shut up and calculate, then, recognizes that there are limits to our pathways for understanding. Our only option as scientists is to look, predict and test. This might not be as glamorous an offering as the interpretations we can construct in our minds, but it is the royal road to real knowledge…

As we muse on meaning, we might recall that it was on this date in 1954 that the official ground-breaking for CERN (Conseil européen pour la recherche nucléaire) was held. Located in Switzerland, it is the largest particle physics laboratory in the world… that’s to say, a prime spot to do the observation and calculation that Andersen suggests. Indeed, it’s been the site of many breakthrough discoveries over the years, maybe most notably the 2012 observation of the Higgs Boson.

Because researchers need remote access to these facilities, the lab has historically been a major wide area network hub. Indeed, it was at CERN that Tim Berners-Lee developed the first “browser”– and effectively fomented the emergence of the web.

facial analysis

Humans have long hungered for a short-hand to help in understanding and managing other humans.  From phrenology to the Myers-Briggs Test, we’ve tried dozens of short-cuts… and tended to find that at best they weren’t actually very helpful; at worst, they were reinforcing of stereotypes that were inaccurate, and so led to results that were unfair and ineffective.  Still, the quest continues– these days powered by artificial intelligence.  What could go wrong?…

Could a program detect potential terrorists by reading their facial expressions and behavior? This was the hypothesis put to the test by the US Transportation Security Administration (TSA) in 2003, as it began testing a new surveillance program called the Screening of Passengers by Observation Techniques program, or Spot for short.

While developing the program, they consulted Paul Ekman, emeritus professor of psychology at the University of California, San Francisco. Decades earlier, Ekman had developed a method to identify minute facial expressions and map them on to corresponding emotions. This method was used to train “behavior detection officers” to scan faces for signs of deception.

But when the program was rolled out in 2007, it was beset with problems. Officers were referring passengers for interrogation more or less at random, and the small number of arrests that came about were on charges unrelated to terrorism. Even more concerning was the fact that the program was allegedly used to justify racial profiling.

Ekman tried to distance himself from Spot, claiming his method was being misapplied. But others suggested that the program’s failure was due to an outdated scientific theory that underpinned Ekman’s method; namely, that emotions can be deduced objectively through analysis of the face.

In recent years, technology companies have started using Ekman’s method to train algorithms to detect emotion from facial expressions. Some developers claim that automatic emotion detection systems will not only be better than humans at discovering true emotions by analyzing the face, but that these algorithms will become attuned to our innermost feelings, vastly improving interaction with our devices.

But many experts studying the science of emotion are concerned that these algorithms will fail once again, making high-stakes decisions about our lives based on faulty science…

“Emotion detection” has grown from a research project to a $20bn industry; learn more about why that’s a cause for concern: “Don’t look now: why you should be worried about machines reading your emotions.”

As we insist on the individual, we might recall that it was on this date in 1989 that Tim Berners-Lee submitted a proposal to CERN for developing a new way of linking and sharing information over the Internet.

It was the first time Berners-Lee proposed a system that would ultimately become the World Wide Web; but his proposal was basically a relatively vague request to research the details and feasibility of such a system.  He later submitted a proposal on November 12, 1990 that much more directly detailed the actual implementation of the World Wide Web.

“Printing…is the preservative of all arts”*…

In 366, the itinerant monk Yuezun was wandering through the arid landscape [around the Western Chinese city of Dunhuang] when a fantastical sight appeared before him: a thousand buddhas, bathed in golden light. (Whether heat, exhaustion or the strange voice of the sands worked themselves on his imagination is anyone’s guess.) Awed by his vision, Yuezun took up hammer and chisel and carved a devotional space into a nearby cliff-face. It soon became a centre for religion and art: Dunhuang was situated at the confluence of two major Silk Road routes, and both departing and returning merchants made offerings. By the time the site fell into disuse in the 14th century, almost 500 temples had been carved from the cliff.

Among the hundreds of caves was a chamber that served as a storeroom for books. The Library Cave held more than 50,000 texts: religious tracts, business reports, calendars, dictionaries, government documents, shopping lists, and the oldest dated printed book in the world. A colophon at the end of the Dunhuang Diamond Sūtra scroll dates it to 868, nearly six centuries before the first Gutenberg Bible…

As we treasure tomes, we might recall that it was on this date in 1990 that  Tim Berners-Lee published a formal proposal for aa “Hypertext project” that he called the World Wide Web (though at the time he rendered it in one word: “WorldWideWeb”)… laying the foundation for a network that has become central to the information age– a network that, with its connected technologies, is believed by many to have sparked a revolution as fundamental and impactful as the revolution ignited by Gutenberg and moveable type.

As we hold our heads in our hands, we might recall that it was on this date in 1989 that Tim Berners-Lee submitted a proposal to CERN for developing a new way of linking and sharing information over the Internet.  It was the first time Berners-Lee proposed the system that would ultimately become the World Wide Web, so this date is oft cited as the “Birthday of the Web.”  But his pitch was a bit vague, and got no traction.  He resubmitted a second, more detailed proposal on November 12, 1990– on which CERN acted…  so many consider this later date the Web’s inception.

“The very existence of libraries affords the best evidence that we may yet have hope for the future of man”*…

 

The Annual Library Budget Survey, a global study that queries 686 senior librarians about their budget spending predictions for the year, was published last week by the Publishers Communication Group (PCG), a consultancy wing of Ingenta, the self-described “largest supplier of technology and related services for the publishing industry.” The survey found uneven growth expectations for libraries worldwide…

As we keep our voices down, we might send informative birthday greetings to Sir Timothy John Berners-Lee OM KBE FRS FREng FRSA FBCS; he was born on this date in 1955.  While working as a Fellow at CERN in 1989, he invented the World Wide Web, developing and demonstrating the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the Internet.  Currently the director of the World Wide Web Consortium (W3C), which oversees the continued development of the Web, he remains a staunch defender of an open Web and the free flow of information.
