Jamie Catherwood with the story of an inspired Catholic priest and hard-earned belief…
Two days before the wildly popular World’s Fair in his city came to an end, on October 30, 1893, a disturbed office seeker shot and killed the Mayor of Chicago in his own home… This devastated Chicago and America more broadly. This high-profile assassination detracted from a triumphant World’s Fair, which showcased American strength and global prominence.
For whatever reason, it really devastated… Catholic Priest, Casimir Zeglen. A local newspaper reported:
“the sensitive priest was shocked more than most people, because it occurred to him that there must be some way to create bullet-proof clothing that would protect people who, by their position, are most vulnerable to fanatics.”
And so… Zeglen began designing a bullet-proof vest… Around this time, there were a few publicized cases of men being shot in the chest and surviving because a silk handkerchief in their breast pockets, folded a few times, had stopped the bullet. This inspired Zeglen to explore the application of silk on a larger scale: bulletproof vests. He spent two years experimenting and tinkering, and in 1897 Zeglen received two patents from the USPTO for his invention: “armor protecting against bullets from a handgun.”
Although he was not always the target, Zeglen frequently placed himself in the line of fire during public demonstrations (Source)… How much conviction must you have in your own research to willingly place yourself in harm’s way? And that’s just it. True conviction can only come from deep research and long hours. Doing the work.
I’d never let someone shoot me while wearing a silk vest unless I’d spent thousands of hours researching, building, iterating, and studying everything there is to know about bulletproof materials.
Yet Zeglen had done just that. Backed by meticulous research and years of trial and error, Casimir Zeglen demonstrated his invention before the new Chicago Mayor – four years after the assassination of his predecessor – and the Chicago Police Department…

As we do the work, we might recall that it was on this date in 1946 that Annie Get Your Gun opened at the Imperial Theater on Broadway. With a score by Irving Berlin and a book by Dorothy Fields and her brother Herbert Fields, it told the fictionalized story of Annie Oakley (1860–1926), a sharpshooter who starred in Buffalo Bill’s Wild West, and her romance with sharpshooter Frank E. Butler (1847–1926).
It was huge hit, running for 1,147 performances, and spawned revivals, a 1950 film version and television versions. Songs that became hits include “There’s No Business Like Show Business“, “Doin’ What Comes Natur’lly“, “You Can’t Get a Man with a Gun“, “They Say It’s Wonderful“, and “Anything You Can Do (I Can Do Better).”

Andrei Zheleznyakov, a Soviet scientist, was developing chemical weapons in 1987 when a hood malfunction exposed him to traces of the nerve agent Novichok 5. He spent weeks in a coma, months unable to walk, and years suffering failing health before dying from its effects in 1992/3…

Thomas Midgley, Jr. (1889–1944) was an American engineer and chemist who contracted polio at age 51, leaving him severely disabled. He devised an elaborate system of ropes and pulleys to help others lift him from bed. He became accidentally entangled in the ropes and died of strangulation at the age of 55. However, he is better known for two of his other inventions: the tetraethyl lead (TEL) additive to gasoline, and chlorofluorocarbons (CFCs) [as we’ve noted in (Roughly) Daily before]…

As we practice prudence, we might spare a thought for F. Sherwood Rowland; he died on this date in 2012. A chemist who focused on atmospheric chemistry, he is best remembered as the man who “outed” Thomas Midgley– that’s to say, for his discovery that chlorofluorocarbons contribute to ozone depletion– for which he shared 1995 Nobel Prize for Chemistry.

… or, as Confucius would have it, “real knowledge is to know the extent of one’s ignorance.” Happily Wikenigma is here to help…
Wikenigma is a unique wiki-based resource specifically dedicated to documenting fundamental gaps in human knowledge.
Listing scientific and academic questions to which no-one, anywhere, has yet been able to provide a definitive answer. [949 so far]
That’s to say, a compendium of so-called ‘Known Unknowns’…
Consider, for example…
How do marine turtle accurately migrate thousands of kilometers for nesting?
Can Beal’s conjecture be proved?
Can one solve the “envelope paradox”?
Do “naked singularities” exist?
What is the etymology of the word “plot” (which appears only in English)?
What are the function, importance, and evolutionary history of human “inner speech”?

As we wonder, we might spare a thought for a man who embodied curiosity, Marvin Minsky; he died on this date in 2016. A biochemist and cognitive scientist by training, he was founding director of MIT’s Artificial Intelligence Project (the MIT AI Lab). Minsky authored several widely-used texts, and made many contributions to AI, cognitive psychology, mathematics, computational linguistics, robotics, and optics. He holds several patents, including those for the first neural-network simulator (SNARC, 1951), the first head-mounted graphical display, the first confocal scanning microscope, and the LOGO “turtle” device (with his friend and frequent collaborator Seymour Papert). His other inventions include mechanical hands and the “Muse” synthesizer.

As Joel David Hamkins explains, an ancient puzzle leads ultimately to a remarkable observation on the malleable nature of infinite sums…
The Greek philosopher Zeno of Elea (c. 490–430 BC) argued in antiquity that all motion is impossible. It is simply impossible to walk through town or even across the room, to go from here to there. What? We know, of course, that this is possible—we walk from here to there every day. And yet, Zeno offers us his proof that this is an illusion—we simply cannot do it.
Zeno argued like this. Suppose it were possible for you to move from some point A to another distinct point B.
Before you complete the move from A to B , however, you must of course have gotten half way there.
But before you get to this half-way point, of course, you must get half way to the half-way point! And before you get to that place, you must get half way there.
And so on, ad infinitum.
Thus, to move from A to B , or indeed anywhere at all, one must have completed an infinite number of tasks—a supertask. It follows, according to Zeno, that you can never start moving—you cannot move any amount at all, since before doing that you must already have moved half as much. And so, contrary to appearances, you are frozen motionless, unable to begin. All motion is impossible.
Is the argument convincing? On what grounds would you object to it? Do you think, contrary to Zeno, that we can actually complete infinitely many tasks? How would that be possible?
It will be no good, of course, to criticize Zeno’s argument on the grounds that we know that motion is possible, for we move from one point to another every day. That is, to argue merely that the conclusion is false does not actually tell you what is wrong with the argument—it does not identify any particular flaw in Zeno’s reasoning. After all, if it were in fact an illusion that we experience motion, then your objection would be groundless…

As we interrogate infinity, we might send-well-groomed birthday greetings to Frank Joseph Zamboni, Jr.; he was born on this date in 1901. An engineer and inventor, he is best known for the modern ice resurfacer, seen at work at hockey games and figure skating competitions (completing its rounds, Zeno notwithstanding); indeed, his surname is the registered trademark for these devices.
“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.
