The revered New York Times bestselling author traces the development of technology from the Industrial Age to the Digital Age to explore the single component crucial to advancement—precision—in a superb history that is both an homage and a warning for our future.
The rise of manufacturing could not have happened without an attention to precision. At the dawn of the Industrial Revolution in eighteenth-century England, standards of measurement were established, giving way to the development of machine tools—machines that make machines. Eventually, the application of precision tools and methods resulted in the creation and mass production of items from guns and glass to mirrors, lenses, and cameras—and eventually gave way to further breakthroughs, including gene splicing, microchips, and the Hadron Collider.
Simon Winchester takes us back to origins of the Industrial Age, to England where he introduces the scientific minds that helped usher in modern production: John Wilkinson, Henry Maudslay, Joseph Bramah, Jesse Ramsden, and Joseph Whitworth. It was Thomas Jefferson who later exported their discoveries to the fledgling United States, setting the nation on its course to become a manufacturing titan. Winchester moves forward through time, to today’s cutting-edge developments occurring around the world, from America to Western Europe to Asia.
As he introduces the minds and methods that have changed the modern world, Winchester explores fundamental questions. Why is precision important? What are the different tools we use to measure it? Who has invented and perfected it? Has the pursuit of the ultra-precise in so many facets of human life blinded us to other things of equal value, such as an appreciation for the age-old traditions of craftsmanship, art, and high culture? Are we missing something that reflects the world as it is, rather than the world as we think we would wish it to be? And can the precise and the natural co-exist in society?
One of my favorite all-time writers and somehow I had missed any news about its pending release and hadn’t seen it despite having just been to the bookstore. What a fantastic surprise!

Investigating information storage and processing in biological systems
We work on novel ways to understand and control complex pattern formation. We use techniques of molecular genetics, biophysics, and computational modeling to address large-scale control of growth and form. We work in whole frogs and flatworms, and sometimes zebrafish and human tissues in culture. Our projects span regeneration, embryogenesis, cancer, and learning plasticity – all examples of how cellular networks process information. In all of these efforts, our goal is not only to understand the molecular mechanisms necessary for morphogenesis, but also to uncover and exploit the cooperative signaling dynamics that enable complex bodies to build and remodel themselves toward a correct structure. Our major goal is to understand how individual cell behaviors are orchestrated towards appropriate large-scale outcomes despite unpredictable environmental perturbations.
Paul Holes was on the verge of retirement, having never completed his decades-long mission to catch the Golden State Killer. Then he had an idea: Upload DNA evidence to a genealogy website.
On today’s episode:
• Paul Holes, an investigator in California who helped to crack the case.
• A spate of murders and rapes across California in the 1970s and 1980s went unsolved for decades. Then, last week, law enforcement officials arrested Joseph James DeAngelo, 72, a former police officer.
• Investigators submitted DNA collected at a crime scene to the genealogy website GEDmatch, through which they were able to track down distant relatives of the suspect. The method has raised concerns about privacy and ethics.
A stunning story with some ingenious detective work. I worry what the potential privacy problems are off in the future, though one of the ideas here is that it actually helps protect the privacy of some individuals who are wrongly and maliciously accused and thus saves a lot of time and money.
The subtleties will be when we’re using this type of DNA evidence more frequently for lower level crimes while at the same time the technology gets increasingly cheaper to carry out.Syndicated copies to:
An ambitious study in yeast shows that the health of cells depends on the highly intertwined effects of many genes, few of which can be deleted together without consequence.
There could be some interesting data to play with here if available.
I also can’t help but wonder about applying some of Stuart Kauffman’s ideas to something like this. In particular, this sounds very reminiscent to his analogy of what happens when one strings thread randomly among a pile of buttons and the resulting complexity.Syndicated copies to:
The competition, whose finals play out tonight, is as famed for its politics as its cheesy
I often read the Economist’s Espresso daily round up, but don’t explicitly post that I do. I’m making an exception in this case because I find the voting partnerships mentioned here quite interesting. Might be worth delving into some of the underlying voting statistics for potential application to other real life examples. I’m also enamored of the nice visualization they provide. I wonder what the overlap of this data is with other related world politics looks like?

“Professionals and amateurs in a variety of fields have passionately argued for either one or two spaces following this punctuation mark,” they wrote in a paper published last week in the journal Attention, Perception, & Psychophysics.
They cite dozens of theories and previous research, arguing for one space or two. A 2005 study that found two spaces reduced lateral interference in the eye and helped reading. A 2015 study that found the opposite. A 1998 experiment that suggested it didn't matter.
“However,” they wrote, “to date, there has been no direct empirical evidence in support of these claims, nor in favor of the one-space convention.”
I love that the permalink for this article has a trailing 2, which indicates to me that it took the editors a second attempt to add the additional space into the headline for their CMS. And if nothing else, this article is interesting for its layout and typesetting.
I’ll circle back to read the full journal article shortly.1

Let’s be honest, reading a paper:
1. Read abstract
2. Look at pictures
3. Scan conclusions
4. Read 2-3 paragraphs of lit review
5. Scan references in case you’ve missed something juicy
6. Ear-mark to read ‘properly’ later
7. Take on all train journeys for next year. Don’t read.

Archaeologists in Sudan have uncovered the largest assemblage of Meroitic inscriptions to date
This is a cool discovery, in great part because their documentation was interesting enough to be able to suggest further locations to check for more archaeological finds. This might also be something one could apply some linguistic analysis and information theory to in an attempt to better pull apart the language and grammar.

Dear god, I wish Ilyas had a traditional blog with a true feed, but I’m willing to put up with the inconvenience of manually looking him up from time to time to see what he’s writing about quantum mechanics, quantum computing, category theory, and other areas of math.
I just finished a course on Algebraic Geometry through UCLA Extension, which was geared toward non-traditional math students and professionals, and wish I had known about Smith’s textbook when I’d started. I did spend some time with Cox, Little, and O’Shea’s Ideals, Varieties, and Algorithms which is a pretty good introduction to the area, but written a bit more for computer scientists and engineers in mind rather than the pure mathematician, which might recommend it more toward your audience here as well. It’s certainly more accessible than Hartshorne for the faint-of-heart.
I’ve enjoyed your prior articles on category theory which have spurred me to delve deeper into the area. For others who are interested, I thought I’d also mention that physicist and information theorist John Carlos Baez at UCR has recently started an applied category theory online course which I suspect is a bit more accessible than most of the higher graduate level texts and courses currently out. For more details, I’d suggest starting here: https://johncarlosbaez.wordpress.com/2018/03/26/seven-sketches-in-compositionality/Syndicated copies to:
