“If someone separated the art of counting and measuring and weighing from all the other arts, what was left of each (of the others) would be, so to speak, insignificant”*…
Mathematics, Bo Malmberg and Hannes Malmberg argue, was the cornerstone of the Industrial Revolution. A new paradigm of measurement and calculation, more than scientific discovery, built industry, modernity, and the world we inhabit today…
In school, you might have heard that the Industrial Revolution was preceded by the Scientific Revolution, when Newton uncovered the mechanical laws underlying motion and Galileo learned the true shape of the cosmos. Armed with this newfound knowledge and the scientific method, the inventors of the Industrial Revolution created machines – from watches to steam engines – that would change everything.
But was science really the key? Most of the significant inventions of the Industrial Revolution were not undergirded by a deep scientific understanding, and their inventors were not scientists.
The standard chronology ignores many of the important events of the previous 500 years. Widespread trade expanded throughout Europe. Artists began using linear perspective and mathematicians learned to use derivatives. Financiers started joint stock corporations and ships navigated the open seas. Fiscally powerful states were conducting warfare on a global scale.
There is an intellectual thread that runs through all of these advances: measurement and calculation. Geometric calculations led to breakthroughs in painting, astronomy, cartography, surveying, and physics. The introduction of mathematics in human affairs led to advancements in accounting, finance, fiscal affairs, demography, and economics – a kind of social mathematics. All reflect an underlying ‘calculating paradigm’ – the idea that measurement, calculation, and mathematics can be successfully applied to virtually every domain. This paradigm spread across Europe through education, which we can observe by the proliferation of mathematics textbooks and schools. It was this paradigm, more than science itself, that drove progress. It was this mathematical revolution that created modernity…

As we muse on measurement, we might recall that it was on this date in 1790, early in the French Revolution, that the French Assembly, acting on the urging of Bishop Charles Maurice de Talleyrand, moved to create a new system of weights and measures based on natural units– what we now know as the metric system.

The scientific literature is vast. No individual human can fully know all the published research findings, even within a single field of science. As Ulkar Aghayeva explains, regardless of how much time a scientist spends reading the literature, there’ll always be what the information scientist Don Swanson called ‘undiscovered public knowledge’: knowledge that exists and is published somewhere, but still remains largely unknown.
Some scientific papers receive very little attention after their publication – some, indeed, receive no attention whatsoever. Others, though, can languish with few citations for years or decades, but are eventually rediscovered and become highly cited. These are the so-called ‘sleeping beauties’ of science.
The reasons for their hibernation vary. Sometimes it is because contemporaneous scientists lack the tools or practical technology to test the idea. Other times, the scientific community does not understand or appreciate what has been discovered, perhaps because of a lack of theory. Yet other times it’s a more sublunary reason: the paper is simply published somewhere obscure and it never makes its way to the right readers.
What can sleeping beauties tell us about how science works? How do we rediscover information the scientific body of knowledge already contains but that is not widely known? Is it possible that, if we could understand sleeping beauties in a more systematic way, we might be able to accelerate scientific progress?
Sleeping beauties are more common than you might expect.
The term sleeping beauties was coined by Anthony van Raan, a researcher in quantitative studies of science, in 2004. In his study, he identified sleeping beauties between 1980 and 2000 based on three criteria: first, the length of their ‘sleep’ during which they received few if any citations. Second, the depth of that sleep – the average number of citations during the sleeping period. And third, the intensity of their awakening – the number of citations that came in the four years after the sleeping period ended. Equipped with (somewhat arbitrarily chosen) thresholds for these criteria, van Raan identified sleeping beauties at a rate of about 0.01 percent of all published papers in a given year.
Later studies hinted that sleeping beauties are even more common than that. A systematic study in 2015, using data from 384,649 papers published in American Physical Society journals, along with 22,379,244 papers from the search engine Web of Science, found a wide, continuous range of delayed recognition of papers in all scientific fields. This increases the estimate of the percentage of sleeping beauties at least 100-fold compared to van Raan’s.
Many of those papers became highly influential many decades after their publication – far longer than the typical time windows for measuring citation impact. For example, Herbert Freundlich’s paper ‘Concerning Adsorption in Solutions’ (though its original title is in German) was published in 1907, but began being regularly cited in the early 2000s due to its relevance to new water purification technologies. William Hummers and Richard Offeman’s ‘Preparation of Graphitic Oxide’, published in 1958, also didn’t ‘awaken’ until the 2000s: in this case because it was very relevant to the creation of the soon-to-be Nobel Prize–winning material graphene…
Indeed, one of the most famous physics papers, Albert Einstein, Boris Podolsky, and Nathan Rosen (EPR)’s ‘Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?’ (1935) is a classic example of a sleeping beauty…

As we dwell on discovery, we might send healing birthday greetings to a woman whose scientific work thankfully rarely napped, Gertrude Elion; she was born on this date in 1918. A pharmacologist, she shared the 1988 Nobel Prize in Physiology or Medicine with George H. Hitchings and Sir James Black for their use of innovative methods of rational drug design (focused on understanding the target of the drug rather than simply using trial-and-error) in the development of new drugs. Her work led to the creation of the anti-retroviral drug AZT, which was the first drug widely used against AIDS. Her well-known and widely deployed creations also include the first immunosuppressive drug, azathioprine, used to fight rejection in organ transplants, the first successful antiviral drug, acyclovir (ACV), used in the treatment of herpes infection, and a number of drugs used in cancer treatment.

The amazing life of “Gudrid the Far-Traveled” has, Frank Jacobs argues, been unjustly overshadowed by her in-laws, Erik the Red and Leif Erikson…
She’s been called “the greatest female explorer of all time,” and the “best-traveled woman of the Middle Ages.” Just after the year 1000 AD, she gave birth to the first European baby in North America. And she concluded her global odyssey with a pilgrimage on foot to Rome. Yet few today can name this extraordinary Viking lady, even if they have heard of Erik the Red and Leif Erikson, her father- and brother-in-law…

As we tag along, we might recall that this date in 2014 was purportedly the date of the final battle in Ragnarök, a series of events (many natural disasters) culminating in a catastrophic battle and the end of the world-as-we-know-it: giants and demons approach from all points of the compass and attack the gods (Odin, Thor, Týr, Freyr, Heimdall, Loki, et al.), who meet them and face death like heroes. At the conflict’s end, the sun darkens, the stars vanish, and the earth sinks into the sea. (Happily, afterward, the earth rises again, the innocent Balder returns from the dead, and leads hosts of the just to a life in a hall roofed with gold.)
In the event, of course, the world did not end that day. The prediction had been promoted by the Jorvik Viking Centre in York, England, intended to draw attention to an event that the institution was to hold on that date. In an obvious lift from the 2012 Mayan Prophecy frenzy, the Centre attributed the claim to a “Viking Calendar,” though no such calendar is known to have existed. Authentic scholars were predictably (and understandably) irked, though as philologist Joseph Hopkins noted, the media response was an example of a broad revival of interest in the Viking Age and ancient Germanic topics.
(Historians believe that Gudrid did in fact exist and did make the journeys discussed above.)
“There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.”*…
Some observations are best considered “interesting, if true”; some, a la Karl Popper, “true, until false”… Consider this very recent paper in Nature…
Theories of scientific and technological change view discovery and invention as endogenous processes, wherein previous accumulated knowledge enables future progress by allowing researchers to, in Newton’s words, ‘stand on the shoulders of giants.’ Recent decades have witnessed exponential growth in the volume of new scientific and technological knowledge, thereby creating conditions that should be ripe for major advances. Yet contrary to this view, studies suggest that progress is slowing in several major fields. Here, we analyse these claims at scale across six decades, using data on 45 million papers and 3.9 million patents from six large-scale datasets, together with a new quantitative metric—the CD index—that characterizes how papers and patents change networks of citations in science and technology. We find that papers and patents are increasingly less likely to break with the past in ways that push science and technology in new directions. This pattern holds universally across fields and is robust across multiple different citation- and text-based metrics. Subsequently, we link this decline in disruptiveness to a narrowing in the use of previous knowledge, allowing us to reconcile the patterns we observe with the ‘shoulders of giants’ view. We find that the observed declines are unlikely to be driven by changes in the quality of published science, citation practices or field-specific factors. Overall, our results suggest that slowing rates of disruption may reflect a fundamental shift in the nature of science and technology.

One notes that the quote above– from Lord Kelvin, at the turn of the twentieth century– immediately preceded a couple of decades in which physics was radically redefined and advanced by Planck, Einstein, Bohr, et al. (In fairness to Kelvin, consider this suggestion that his point was more subtle.) As we look forward, we might ponder the ways in which the reorganization of disciplines, the rise of research in other cultures (less constrained by the mores of “conventional” research), the use of AI, and/or some as yet unknown dynamic could challenge the phenomenon– “a narrowing in the use of previous knowledge”– to which the authors attribute diminishing disruption.

As we ponder progress, we might send advanced birthday greetings to Wilhelm Wien; he was born on this date in 1864. A physicist, his work helped move past Kelvin’s log-jam. In 1893, he used theories about heat and electromagnetism to deduce Wien’s displacement law, which calculates the emission of a blackbody (a surface that absorbs all radiant energy falling on it) at any temperature from the emission at any one reference temperature. His colleague Max Planck colaborated with Wien, then extended the thinking in what we now know as Planck’s law, which led to the development of quantum theory.
Wien received the 1911 Nobel Prize for his work on heat radiation.
Just before Kelvin’s speech (in 1898) Wien identified a positive particle equal in mass to the hydrogen atom– what we now know as a proton. Wien, in the techniques he used, laid the foundation of mass spectrometry.

As we scrutinize scale, we might recall that it was on this date in 1988 that NASA, undaunted by distance, launched the Space Shuttle Discovery (which had been out of service for three years), marking America’s return to manned space flight following the Challenger disaster. By its last mission in 2011, Discovery had flown 149 million miles in 39 missions, completed 5,830 orbits, and spent 365 days in orbit over 27 years.
