FrogHeart’s 2024 comes to an end as 2025 comes into view

Leave a reply

First, thank you to anyone who’s dropped by to read any of my posts. Second, I didn’t quite catch up on my backlog in what was then the new year (2024) despite my promises. (sigh) I will try to publish my drafts in a more timely fashion but I start this coming year as I did 2024 with a backlog of two to three months. This may be my new normal.

As for now, here’s an overview of FrogHeart’s 2024. The posts that follow are loosely organized under a heading but many of them could fit under other headings as well. After my informal review, there’s some material on foretelling the future as depicted in an exhibition, “Oracles, Omens and Answers,” at the Bodleian Libraries, University of Oxford.

Human enhancement: prosthetics, robotics, and more

Within a year or two of starting this blog I created a tag ‘machine/flesh’ to organize information about a number of converging technologies such as robotics, brain implants, and prosthetics that could alter our concepts of what it means to be human. The larger category of human enhancement functions in much the same way also allowing a greater range of topics to be covered.

Here are some of the 2024 human enhancement and/or machine/flesh stories on this blog,

Other species are also being rendered ‘machine/flesh’,

The year of the hydrogel?

It was the year of the hydrogel for me (btw, hydrogels are squishy materials; I have more of a description after this list),

As for anyone who’s curious about hydrogels, there’s this from an October 20, 2016 article by D.C.Demetre for ScienceBeta, Note: A link has been removed,

Hydrogels, materials that can absorb and retain large quantities of water, could revolutionise medicine. Our bodies contain up to 60% water, but hydrogels can hold up to 90%.

It is this similarity to human tissue that has led researchers to examine if these materials could be used to improve the treatment of a range of medical conditions including heart disease and cancer.

These days hydrogels can be found in many everyday products, from disposable nappies and soft contact lenses to plant-water crystals. But the history of hydrogels for medical applications started in the 1960s.

Scientists developed artificial materials with the ambitious goal of using them in permanent contact applications , ones that are implanted in the body permanently.

For anyone who wants a more technical explanation, there’s the Hydrogel entry on Wikipedia.

Science education and citizen science

Where science education is concerned I’m seeing some innovative approaches to teaching science, which can include citizen science. As for citizen science (also known as, participatory science) I’ve been noticing heightened interest at all age levels.

Artificial intelligence

It’s been another year where artificial intelligence (AI) has absorbed a lot of energy from nearly everyone. I’m highlighting the more unusual AI stories I’ve stumbled across,

As you can see, I’ve tucked in two tangentially related stories, one which references a neuromorphic computing story ((see my Neuromorphic engineering category or search for ‘memristors’ in the blog search engine for more on brain-like computing topics) and the other is intellectual property. There are many, many more stories on these topics

Art/science (or art/sci or sciart)

It’s a bit of a surprise to see how many art/sci stories were published here this year, although some might be better described as art/tech stories.

There may be more 2024 art/sci stories but the list was getting long. In addition to searching for art/sci on the blog search engine, you may want to try data sonification too.

Moving off planet to outer space

This is not a big interest of mine but there were a few stories,

A writer/blogger’s self-indulgences

Apparently books can be dangerous and not in a ‘ban [fill in the blank] from the library’ kind of way,

Then, there are these,

New uses for electricity,

Given the name for this blog, it has to be included,

  • Frog saunas published September 15, 2024, this includes what seems to be a mild scientific kerfuffle

I’ve been following Lomiko Metals (graphite mining) for a while,

Who would have guessed?

Another bacteria story,

New crimes,

Origins of life,

Dirt

While no one year features a large number of ‘dirt’ stories, it has been a recurring theme here throughout the years,

Regenerative medicine

In addition to or instead of using the ‘regenerative medicine’ tag, I might use ’tissue engineering’ or ’tissue scaffolding’,

To sum it up

It was an eclectic year.

Peering forward into 2025 and futurecasting

I expect to be delighted, horrified, thrilled, and left shaking my head by science stories in 2025. Year after year the world of science reveals a world of wonder.

More mundanely, I can state with some confidence that my commentary (mentioned in the future-oriented subsection of my 2023 review and 2024 look forward) on Quantum Potential, a 2023 report from the Council of Canadian Academies, will be published early in this new year as I’ve almost finished writing it.

As for more about the future, I’ve got this, from a December 3, 2024 essay (Five ways to predict the future from around the world – from spider divination to bibliomancy) about an exhibition by Michelle Aroney (Research Fellow in Early Modern History, University of Oxford) and David Zeitlyn (Professor of Social Anthropology, University of Oxford) in The Conversation (h/t December 3, 2024 news item on phys.org), Note: Links have been removed

Some questions are hard to answer and always have been. Does my beloved love me back? Should my country go to war? Who stole my goats?

Questions like these have been asked of diviners around the world throughout history – and still are today. From astrology and tarot to reading entrails, divination comes in a wide variety of forms.

Yet they all address the same human needs. They promise to tame uncertainty, help us make decisions or simply satisfy our desire to understand.

Anthropologists and historians like us study divination because it sheds light on the fears and anxieties of particular cultures, many of which are universal. Our new exhibition at Oxford’s Bodleian Library, Oracles, Omens & Answers, explores these issues by showcasing divination techniques from around the world.

…

1. Spider divination

In Cameroon, Mambila spider divination (ŋgam dù) addresses difficult questions to spiders or land crabs that live in holes in the ground.

Asking the spiders a question involves covering their hole with a broken pot and placing a stick, a stone and cards made from leaves around it. The diviner then asks a question in a yes or no format while tapping the enclosure to encourage the spider or crab to emerge. The stick and stone represent yes or no, while the leaf cards, which are specially incised with certain meanings, offer further clarification.

…

2. Palmistry

Reading people’s palms (palmistry) is well known as a fairground amusement, but serious forms of this divination technique exist in many cultures. The practice of reading the hands to gather insights into a person’s character and future was used in many ancient cultures across Asia and Europe.

In some traditions, the shape and depth of the lines on the palm are richest in meaning. In others, the size of the hands and fingers are also considered. In some Indian traditions, special marks and symbols appearing on the palm also provide insights.

Palmistry experienced a huge resurgence in 19th-century England and America, just as the science of fingerprints was being developed. If you could identify someone from their fingerprints, it seemed plausible to read their personality from their hands.

…

3. Bibliomancy

If you want a quick answer to a difficult question, you could try bibliomancy. Historically, this DIY [do-it-yourself] divining technique was performed with whatever important books were on hand.

Throughout Europe, the works of Homer or Virgil were used. In Iran, it was often the Divan of Hafiz, a collection of Persian poetry. In Christian, Muslim and Jewish traditions, holy texts have often been used, though not without controversy.

…

4. Astrology

Astrology exists in almost every culture around the world. As far back as ancient Babylon, astrologers have interpreted the heavens to discover hidden truths and predict the future.

…

5. Calendrical divination

Calendars have long been used to divine the future and establish the best times to perform certain activities. In many countries, almanacs still advise auspicious and inauspicious days for tasks ranging from getting a haircut to starting a new business deal.

In Indonesia, Hindu almanacs called pawukon [calendar] explain how different weeks are ruled by different local deities. The characteristics of the deities mean that some weeks are better than others for activities like marriage ceremonies.

Oracles, Omens and Answers

6 December 2024 – 27 April 2025
ST Lee Gallery, Weston Library

The Bodleian Libraries’ new exhibition, Oracles, Omens and Answers, will explore the many ways in which people have sought answers in the face of the unknown across time and cultures. From astrology and palm reading to weather and public health forecasting, the exhibition demonstrates the ubiquity of divination practices, and humanity’s universal desire to tame uncertainty, diagnose present problems, and predict future outcomes.

Through plagues, wars and political turmoil, divination, or the practice of seeking knowledge of the future or the unknown, has remained an integral part of society. Historically, royals and politicians would consult with diviners to guide decision-making and incite action. People have continued to seek comfort and guidance through divination in uncertain times — the COVID-19 pandemic saw a rise in apps enabling users to generate astrological charts or read the Yijing [I Ching], alongside a growth in horoscope and tarot communities on social media such as ‘WitchTok’. Many aspects of our lives are now dictated by algorithmic predictions, from e-health platforms to digital advertising. Scientific forecasters as well as doctors, detectives, and therapists have taken over many of the societal roles once held by diviners. Yet the predictions of today’s experts are not immune to criticism, nor can they answer all our questions.

Curated by Dr Michelle Aroney, whose research focuses on early modern science and religion, and Professor David Zeitlyn, an expert in the anthropology of divination, the exhibition will take a historical-anthropological approach to methods of prophecy, prediction and forecasting, covering a broad range of divination methods, including astrology, tarot, necromancy, and spider divination.

Dating back as far as ancient Mesopotamia, the exhibition will show us that the same kinds of questions have been asked of specialist practitioners from around the world throughout history. What is the best treatment for this illness? Does my loved one love me back? When will this pandemic end? Through materials from the archives of the Bodleian Libraries alongside other collections in Oxford, the exhibition demonstrates just how universally human it is to seek answers to difficult questions.

Highlights of the exhibition include: oracle bones from Shang Dynasty China (ca. 1250-1050 BCE); an Egyptian celestial globe dating to around 1318; a 16th-century armillary sphere from Flanders, once used by astrologers to place the planets in the sky in relation to the Zodiac; a nineteenth-century illuminated Javanese almanac; and the autobiography of astrologer Joan Quigley, who worked with Nancy and Ronald Reagan in the White House for seven years. The casebooks of astrologer-physicians in 16th- and 17th-century England also offer rare insights into the questions asked by clients across the social spectrum, about their health, personal lives, and business ventures, and in some cases the actions taken by them in response.

The exhibition also explores divination which involves the interpretation of patterns or clues in natural things, with the idea that natural bodies contain hidden clues that can be decrypted. Some diviners inspect the entrails of sacrificed animals (known as ‘extispicy’), as evidenced by an ancient Mesopotamian cuneiform tablet describing the observation of patterns in the guts of birds. Others use human bodies, with palm readers interpreting characters and fortunes etched in their clients’ hands. A sketch of Oscar Wilde’s palms – which his palm reader believed indicated “a great love of detail…extraordinary brain power and profound scholarship” – shows the revival of palmistry’s popularity in 19th century Britain.

The exhibition will also feature a case study of spider divination practised by the Mambila people of Cameroon and Nigeria, which is the research specialism of curator Professor David Zeitlyn, himself a Ŋgam dù diviner. This process uses burrowing spiders or land crabs to arrange marked leaf cards into a pattern, which is read by the diviner. The display will demonstrate the methods involved in this process and the way in which its results are interpreted by the card readers. African basket divination has also been observed through anthropological research, where diviners receive answers to their questions in the form of the configurations of thirty plus items after they have been tossed in the basket.

Dr Michelle Aroney and Professor David Zeitlyn, co-curators of the exhibition, say:

Every day we confront the limits of our own knowledge when it comes to the enigmas of the past and present and the uncertainties of the future. Across history and around the world, humans have used various techniques that promise to unveil the concealed, disclosing insights that offer answers to private or shared dilemmas and help to make decisions. Whether a diviner uses spiders or tarot cards, what matters is whether the answers they offer are meaningful and helpful to their clients. What is fun or entertainment for one person is deadly serious for another.

Richard Ovenden, Bodley’s [a nickname? Bodleian Libraries were founded by Sir Thomas Bodley] Librarian, said:

People have tried to find ways of predicting the future for as long as we have had recorded history. This exhibition examines and illustrates how across time and culture, people manage the uncertainty of everyday life in their own way. We hope that through the extraordinary exhibits, and the scholarship that brings them together, visitors to the show will appreciate the long history of people seeking answers to life’s biggest questions, and how people have approached it in their own unique way.

The exhibition will be accompanied by the book Divinations, Oracles & Omens, edited by Michelle Aroney and David Zeitlyn, which will be published by Bodleian Library Publishing on 5 December 2024.

Archaeomagnetism, anomalies in space, and 3,000-year-old Babylonian bricks

Leave a reply

While i don’t usually cover the topic of magnetic fields, this fascinating research required a combination of science and the humanities, a topic of some interest to me. First, there’s the news and then excerpts from Rae Hodge’s December 25, 2023 commentary “How 3,000-year-old Babylonian tablets help scientists unravel one of the weirdest mysteries in space” for Salon.

A December 19, 2023 University College London (UCL; also on EurekAlert but published December 18, 2023) explains how Babylonian artefacts led to a discovery about earth’s magnetic fields,

Ancient bricks inscribed with the names of Mesopotamian kings have yielded important insights into a mysterious anomaly in Earth’s magnetic field 3,000 years ago, according to a new study involving UCL researchers.

The research, published in the Proceedings of the National Academy of Sciences (PNAS), describes how changes in the Earth’s magnetic field imprinted on iron oxide grains within ancient clay bricks, and how scientists were able to reconstruct these changes from the names of the kings inscribed on the bricks.

The team hopes that using this “archaeomagnetism,” which looks for signatures of the Earth’s magnetic field in archaeological items, will improve the history of Earth’s magnetic field, and can help better date artefacts that they previously couldn’t.

Co-author Professor Mark Altaweel (UCL Institute of Archaeology) said: “We often depend on dating methods such as radiocarbon dates to get a sense of chronology in ancient Mesopotamia. However, some of the most common cultural remains, such as bricks and ceramics, cannot typically be easily dated because they don’t contain organic material. This work now helps create an important dating baseline that allows others to benefit from absolute dating using archaeomagnetism.”

The Earth’s magnetic field weakens and strengthens over time, changes which imprint a distinct signature on hot minerals that are sensitive to the magnetic field. The team analysed the latent magnetic signature in grains of iron oxide minerals embedded in 32 clay bricks originating from archaeological sites throughout Mesopotamia, which now overlaps with modern day Iraq. The strength of the planet’s magnetic field was imprinted upon the minerals when they were first fired by the brickmakers thousands of years ago.

At the time they were made, each brick was inscribed with the name of the reigning king which archaeologists have dated to a range of likely timespans. Together, the imprinted name and the measured magnetic strength of the iron oxide grains offered a historical map of the changes to the strength of the Earth’s magnetic field.

The researchers were able to confirm the existence of the “Levantine Iron Age geomagnetic Anomaly,” a period when Earth’s magnetic field was unusually strong around modern Iraq between about 1050 to 550 BCE for unclear reasons. Evidence of the anomaly has been detected as far away as China, Bulgaria and the Azores, but data from within the southern part of the Middle East itself had been sparse.

Lead author Professor Matthew Howland of Wichita State University said: “By comparing ancient artefacts to what we know about ancient conditions of the magnetic field, we can estimate the dates of any artifacts that were heated up in ancient times.”

To measure the iron oxide grains, the team carefully chipped tiny fragments from broken faces of the bricks and used a magnetometer to precisely measure the fragments.

By mapping out the changes in Earth’s magnetic field over time, this data also offers archaeologists a new tool to help date some ancient artefacts. The magnetic strength of iron oxide grains embedded within fired items can be measured and then matched up to the known strengths of Earth’s historic magnetic field. The reigns of kings lasted from years to decades, which offers better resolution than radiocarbon dating which only pinpoints an artefact’s date to within a few hundred years.

An additional benefit of the archaeomagnetic dating of the artefacts is it can help historians more precisely pinpoint the reigns of some of the ancient kings that have been somewhat ambiguous. Though the length and order of their reigns is well known, there has been disagreement within the archaeological community about the precise years they took the throne resulting from incomplete historical records. The researchers found that their technique lined up with an understanding of the kings’ reigns known to archaeologists as the “Low Chronology”.

The team also found that in five of their samples, taken during the reign of Nebuchadnezzar II from 604 to 562 BCE, the Earth’s magnetic field seemed to change dramatically over a relatively short period of time, adding evidence to the hypothesis that rapid spikes in intensity are possible.

Co-author Professor Lisa Tauxe of the Scripps Institution of Oceanography (US) said: “The geomagnetic field is one of the most enigmatic phenomena in earth sciences. The well-dated archaeological remains of the rich Mesopotamian cultures, especially bricks inscribed with names of specific kings, provide an unprecedented opportunity to study changes in the field strength in high time resolution, tracking changes that occurred over several decades or even less.”

The research was carried out with funding from the U.S.-Israel Binational Science Foundatio

The Humanities and their importance to STEM (science, technology, engineering, and mathematics)

Rae Hodge’s December 25, 2023 commentary explains why magnetic fields might be of interest to a member of the general public (that’s me) and more about the interdisciplinarity, which drove the project, Note 1: This is a US-centric view but the situation in Canada (and I suspect elsewhere) is similar. Note 2: Links have been removed,

Among the most enigmatic mysteries of modern science are the strange anomalies which appear from time to time in the earth’s geomagnetic field. It can seem like the laws of physics behave differently in some places, with unnerving and bizarre results — spacecraft become glitchy, the Hubble Space Telescope can’t capture observations and satellite communications go on the fritz. Some astronauts orbiting past the anomalies report blinding flashes of light and sudden silence. They call one of these massive, growing anomalies the Bermuda Triangle of space — and even NASA [US National Aeronautics and Space Administration] is now tracking it. 

With all the precisely tuned prowess of modern tech turning its eye toward these geomagnetic oddities, you might not expect that some key scientific insights about them could be locked inside a batch of 3,000-year-old Babylonian cuneiform tablets. But that’s exactly what a recently published study in Proceedings of the National Academy of Sciences suggests. 

…

This newly discovered connection between ancient Mesopotamian writing and modern physics is more than an amusing academic fluke. It highlights just how much is at stake for 21st-century scientific progress when budget-slashing lawmakers, university administrators and private industry investors shovel funding into STEM field development while neglecting — and in some case, actively destroying — the humanities.

…

… Despite advances in the past five years or so, archaeomagnetism is still methodologically complex and often tedious work, often cautious data sifting to arrive at accurate interpretations. The more accurate of which come from analyzing layers upon layers of strata. 

But when combined with the expertise of the humanities — from historians and linguists, to religious scholars and anthropologists? Archaeomagnetism opens up new worlds of study across all disciplines. 

In fact, the team’s results show that the strength of the magnetic field in Mesopotamia was more than one and a half times stronger than it is in the area today, with a massive spike happening sometimes between 604 B.C. and 562 B.C. By combining the results of archaeomagnetic tests and the transcriptions of ancient languages on the bricks, the team was able to confirm this spike likely occurred during the reign of Nebuchadnezzar II.

Hand in hand with the sciences, the LIAA [Levantine Iron Age Anomaly] trail was illuminated by historical accounts of descriptively similar events, recorded from ancient authors as far west as the Iberian peninsula and well into Asia. Archaeomagnetism has now allowed researchers to not only confirm the presence of the LIAA in ancient Mesopotamia from 1050 to 550 B.C. — itself a first for science — but offers cultural historians a new way to verify and apply context to a vast tide of early scientific information.

…

Hodge further explores the importance of interdisciplinary work, December 25, 2023 commentary, Note: Links have been removed,

The symbiotic interdependence between the humanities and sciences deepens further in the thicket of time when one considers that the original locations of the team’s fragments likely include the earliest known centers of astrology and mathematics in Sumeria, such as Nineveh near modern-day Mosul, Iraq. At the ancient city’s royal library of the Assyrian Empire, a site dating back to around 650 B.C., a trove of thousands of tablets were excavated in the mid-1800s containing precise astronomical data surpassing that found in any previous discovery.

Among those, the “The Plough Star” tablets bear inscriptions dating to 687 B.C. and are the first known instances of humans tracking lunar and planetary orbits through both the solar ecliptic and 17 constellations. The same trove yielded the awe-striking collection known as the Astronomical Diaries, currently held in the Ashmolean Museum at Oxford, originating from near modern-day Baghdad. The oldest of which dates to 652 B.C. The latest, 61 B.C.

Hermann Hunger and David Pingree, the foremost historians on their excavation, minced no words on their value to to modern science. 

“That someone in the middle of the eighth century BC conceived of such a scientific program and obtained support for it is truly astonishing; that it was designed so well is incredible; and that it was faithfully carried out for 700 years is miraculous,” they wrote.  

In his 2021 book, “A Scheme of Heaven,” data scientist Alexander Boxer cites the two historians and observes that the “enormity of this achievement” lay in the diaries’ preservation of a snapshot of celestial knowledge of the age which — paired with accounts of weather patterns, river water tables, grain prices and even political news — allow us to pinpoint historical events from thousands of years ago, in time-windows as narrow as just a day or two.

“Rivaled only by the extraordinary astronomical records from ancient China, the Babylonian Astronomical Diaries are one of, if not the longest continuous research program ever undertaken,” writes Boxer. 

The cuneiform tablets studied by the UCL team extend this interdisciplinary legacy of the sciences and humanities beautifully by allowing us to read not only the celestially relevant data of geomagnetic history, but by reaffirming the importance of early cultural studies. One fragment, for instance, is dedicated by Nebuchadnezzar II to a temple in Larsa. The site was devoted to carrying out astrological divination traditions, and it’s where we get our earliest clue about the authorship of the Astronomical Diaries. 

Charmingly, that clue appears in the court testimony of a temple official who gets scolded for sounding a false-alarm about an eclipse, embarrassing the temple scholars in front of the whole city.

…

These Neo-Assyrian and Old Babylonian astrologers gave us more than antics, though. In further records at Nineveh, they would ultimately help researchers at the University of Tsukuba [Japan] — some 2,700 years later — track what were likely massive solar magnetic storms in the area, enabled by geomagnetic disruptions that may be yet linked to the LIAA.

In their dutifully recorded daily observations, one astrologer records a “red cloud” while another tablet-writer observes that “red covers the sky” in Babylon.

“These were probably manifestations of what we call today stable auroral red arcs, consisting of light emitted by electrons in atmospheric oxygen atoms after being excited by intense magnetic fields,” the authors said. “These findings allow us to recreate the history of solar activity a century earlier than previously available records…This research can assist in our ability to predict future solar magnetic storms, which may damage satellites and other spacecraft.”

…

Hodge ends with an observation, from her December 25, 2023 commentary,

…

When universities short sell the arts and humanities, we humanities students might lose our poetry, but we can write more. The science folk, on the other hand, might cost themselves another 75 years of research and $70 billion in grants trying to re-invent the Babylonian wheel because the destruction of its historical blueprint was “an arts problem.”

If you have time, do read Hodge’s December 25, 2023 commentary.

Urania Day (celebrating women in the arts and sciences) on March 16, 2021

Leave a reply

I sometimes get notices from unexpected sources for science and technology events. On Tuesday, March 9, 2021, I received a notice from an agency about Urania Day (March 16, 2021) celebrating women in the arts and sciences during (US) Women’s History Month. What made the notice unusual is that the agency was representing Ophira and Tali Edut of AstroStyle, an astrology website.

Astrologers like Galileo, Kepler, Tycho and others

I realize that for a lot people, astrology is a pseudoscience but what is often missed, according to some observers, is that astrology has provided the basis for current astronomy and physics.

Dr . Rebekah Higgott who was Curator of History of Science and Technology at the National Maritime Museum and the Royal Observatory, Greenwich from 2008 – 2013 wrote a thoughtful January 28, 2011 post about astrology and science on Martin Robbins’ Guardian science blog,

…

Like Martin, I heard about the astrologers’ petition to the BBC and blogged about it, together with another astrology-related story that recently hit the headlines. Unlike him, I was critical of the knee-jerk response of many scientists, science writers and fans of science. I also had some quibbles about his post, so I’d like to start by thanking him for hosting this – and, before you leap to the comments section, making it clear that I do not believe in astrology. However, I do believe that a little knowledge and understanding can help the cause of science communication far more than ridicule.

As is well known to readers of The Lay Scientist, the Astrological Association, prompted by remarks made by Brian Cox and Dara O’Briain, has asked for “fair and balanced representation” (note, not “equal representation”). This has resulted in widespread derision from those who can see nothing wrong with stating that “astrology is rubbish” and “nonsense”. Most, however, have failed to understand exactly what has annoyed these astrologers, or to take the time to find out what astrology actually is.

…

The Astrological Association is not complaining about a statement such as this. Rather, they consider it unfair that they are represented as having no knowledge of the astronomy and celestial mechanics that Cox and O’Briain are paid to explain on TV. They are annoyed that astrology is considered to consist solely of those who read and write newspaper horoscopes. Serious astrologers often have an excellent understanding of, and respect for, astronomy. They are, in fact, a not insignificant audience for astronomy programmes, lectures and books.

…

Which brings me to the history: a little historical understanding should make astronomers and science communicators realise that practising astrologers are likely to have good knowledge of planetary motions. Up until the late 17th century, astrology and astronomy were deeply interconnected. [emphasis mine] …

Do read the rest of Higgott’s post for the mentions of Galileo, Kepler, Tycho, and more.

Astrology lays the foundation for data science?

Alexander Boxer’s 2020 book “A Scheme of Heaven: The History of Astrology and the Search for Our Destiny in Data” might seem a bit fanciful. Interestingly, it was discussed by Jonathan Keats in a January 15, 2020 book review for the New Scientist and a January 17, 2020 book review by Steven Vanden Broeck for Science Magazine (Science  17 Jan 2020: Vol. 367, Issue 6475, pp. 255 DOI: 10.1126/science.aaz9644). Both of these reviews are behind paywalls. (There is an open access summary of Vanden Broeck’s review mentioned later in this subsection.)

Here’s more about the book from publisher W. W. Norton’s webpage for A Scheme of Heaven,

An illuminating look at the surprising history and science of astrology, civilization’s first system of algorithms, from Babylon to the present day.

Humans are pattern-matching creatures, and astrology is the universe’s grandest pattern-matching game. In this refreshing work of history and analysis, data scientist Alexander Boxer examines classical texts on astrology to expose its underlying scientific and mathematical framework. Astrology, he argues, was the ancient world’s most ambitious applied mathematics problem, a monumental data-analysis enterprise sustained by some of history’s most brilliant minds, from Ptolemy to al-Kindi to Kepler.

Thousands of years ago, astrologers became the first to stumble upon the powerful storytelling possibilities inherent in numerical data. To correlate the configurations of the cosmos with our day-to-day lives, astrologers relied upon a “scheme of heaven,” or horoscope, showing the precise configuration of the planets at a particular instant in time as viewed from a particular place on Earth. Although recognized as pseudoscience today, horoscopes were once considered a cutting-edge scientific tool. Boxer teaches us how to read these esoteric charts—and appreciate the complex astronomical calculations needed to generate them—by diagramming how the heavens appeared at important moments in astrology’s history, from the assassination of Julius Caesar as viewed from Rome to the Apollo 11 lunar landing as seen from the surface of the Moon. He then puts these horoscopes to the test using modern data sets and statistical science, arguing that today’s data scientists do work similar to astrologers of yore. By looking back at the algorithms of ancient astrology, he suggests, we can better recognize the patterns that are timeless characteristics of our own pattern-matching tendencies.

At once critical, rigorous, and far ranging, A Scheme of Heaven recontextualizes astrology as a vast, technological project—spanning continents and centuries—that foreshadowed our data-driven world today.

I had problems finding Boxer’s credentials, he’s described as a physicist and/or data scientist. Most unusually he does not fully tout his credentials on his eponymous website or anywhere, it seems. Based on a reference to an Alex Boxer in a January 26, 2010 Massachusetts Institute of Technology (MIT) news release, he has a PhD in physics from MIT (this excerpt is from the second paragraph from the bottom),

… A newly installed microwave interferometer array, developed by MIT graduate student Alex Boxer PhD ‘09 [emphasis mine], was used to make the precision measurements of the plasma concentrations that were used to observe the turbulent pinch.

Getting to the open access summary, Science magazine published this brief of Steven Vanden Broecke’s book review in a January 14, 2020 highlight,

Alexander Boxer, a professional data scientist, knows a thing or two about distilling patterns from big data. Surrounded by constant, endless streams of information, humans are pattern-matching animals, and astrology, he claims, “is the universe’s grandest pattern-matching game.”

…

The book also exposes readers to the rigor of statistical analysis. Here, Boxer applies his knowledge of statistics to some of the most enduring and fascinating patterns that astrology educed from its constant comparisons between heavenly and terrestrial events. This combination of topics is usually the preserve of critics, who like to mobilize analyses of astrology’s conceptual apparatus, history, and statistical soundness to demonstrate the art’s vacuity. …

…

A Scheme of Heaven—like all good history writing—turns its subject into a mirror. (In the words of the Roman poet Horatius, “the story is told about you.”) Statistics, Boxer shows, not only debunk astrology’s claims, they confirm that some of our most private behavior happens in step with cosmic rhythms today. History not only documents a distant past, it shows how intimately some of our most prestigious scientific traditions really are—as Johannes Kepler argued—the children of this foolish daughter. And like astrology, the patterns that data science reveals turn out to hinge on far more interpretation than we might like. Boxer points out, for example, how the contemporary combination of big data with machine-learning algorithms is rapidly creating a rift between empirical forecasting models and causal understanding—exactly the kind of rift that has often been invoked to criticize astrology.

Purple hair, Caroline Herschel, and Urania Day

March 16 was chosen as Urania Day to honour Caroline Herschel, an astronomer with an extraordinary history as is made clear in the Urania Day notice,

Urania Day, March 16, to celebrate girls and women in arts and science

during Women’s History Month

Named for the Greek Muse of astronomy, Urania Day falls on the birthday
of groundbreaking astronomer Caroline Herschel, who co-discovered Uranus

Supporters are encouraged to dye their hair purple like the ‘violet-haired’ Muses
to champion the visibility of women in the arts and sciences

#UraniaDay #MarchMuse @astrotwins

NEW YORK – March 5, 2021 – Ophira and Tali Edut, twin founders of astrology multimedia brand AstroStyle, along with astrologer Matthew Swann, have established a new galaxywide holiday: Urania Day. Occurring annually on March 16, birthday of astronomy pioneer Caroline Herschel, and named for the Muse of astronomy, Urania Day’s purpose is to encourage girls and women to literally reach for the stars through science, math and technology.

Urania, the Muse of astronomy in Greek Mythology“As female ‘astropreneurs’ — successful business owners in a creative field — ourselves, my sister Tali and I have been on a mission to empower girls and women since we established AstroStyle in the early 2000s,” explained Ophira, whose website garners more than 10 million pageviews each month. “With Urania Day, we seek to honor the lesser-known, under-credited and virtually forgotten female mavericks of the arts and sciences — starting with Caroline Herschel — and use their stories to inspire today’s young people.”

The Urania Day founders invite any supporters of their mission to be a #MarchMuse and post an image of themselves with purple hair (extensions, wigs and creative dye welcome!) or to share a purple-tinted selfie with the hashtags #UraniaDay and #MarchMuse.

Caroline Herschel, born March 16, 1750, was the younger sister of Sir William Herschel. They both left careers in music to indulge their mutual passion for astronomy and telescope-making. It was Caroline who possessed the craftsmanship to grind and polish their telescope mirrors by hand, and facilitated her brother’s accidental discovery of the planet Uranus on March 13, 1781 using a homemade 6.2-inch reflecting telescope. Beyond this historic accomplishment, Caroline was the first woman to discover a comet, discovering eight comets and three nebulae over the course of her career. She was also the first woman to receive a salary as a scientist, to hold to government position in England, to publish findings in the scientific journal Philosophical Transactions of the Royal Society, to be awarded a Gold Medal of the Royal Astronomical Society (1828), and to be named an Honorary Member of the Royal Astronomical Society (1835, along with Mary Somerville). Caroline also created catalogs of astronomical discoveries that are still in use today. [emphasis mine]

“Uranus the planet was named for Uranus the ancient god of the heavens,” explained Tali. “He was the great-grandfather of Urania and her sisters, the Nine Muses, who were — are — the patron goddesses of the arts and sciences. It’s each Muse’s job to inspire humanity in her area of expertise.”

Visitors to UraniaDay.com are invited to Choose the Muse they most closely relate to:  Urania (astronomy), Clio (history and the guitar), Melpomene (tragedy and rhetoric), Thalia (comedy, geometry, architecture and agriculture), Terpsichore (dance and education), Calliope (epic poetry, inspired The Iliad and The Odyssey), Erato (love poetry), Polyhymnia (grammar, geometry, hymns and mimic art), or Euterpe (lyric poetry).

“Artists are known to ‘invoke the Muse’ when they sit down to write or paint,” she added. “We all invoke the Muse regularly when we use words derived from their name, like ‘music,’ ‘musings’ and ‘amusement.'”

The AstroTwins have also restyled Caroline Herschel’s Urania’s Mirror constellation deck as an all-ages coloring book, which can be downloaded as a free PDF on the Urania Day website.

Happy Urania Day!

Julie Payette, Canada’s Governor General, takes on science deniers and bogus science at 2017 Canadian Science Policy Conference

Leave a reply

On the first day of the 2017 Canadian Science Policy Conference (Nov. 1 -3, 2017 in Ottawa, Ontario), Governor General Julie Payette’s speech encouraged listeners to grapple with science deniers, fake news, and more (from a Nov. 2, 2017 article by Mia Rabson in the Huffington Post, Canada edition),

Payette was the keynote speaker at the ninth annual Canadian Science Policy Convention in Ottawa Wednesday night [Nov. 1, 2017] where she urged her friends and former colleagues to take responsibility to shut down the misinformation about everything from health and medicine to climate change and even horoscopes that has flourished with the explosion of digital media.

“Can you believe that still today in learned society, in houses of government, unfortunately, we’re still debating and still questioning whether humans have a role in the Earth warming up or whether even the Earth is warming up, period,” she asked, her voice incredulous.

…

She generated giggles and even some guffaws from the audience when she said too many people still believe “taking a sugar pill will cure cancer if you will it good enough and that your future and every single one of the people here’s personalities can be determined by looking at planets coming in front of invented constellations.”

Payette was trained as a computer engineer and later became an astronaut and licensed pilot and in 1999 was the first Canadian to board the International Space Station.

…

Mia Rabson in another Nov. 2, 2017 article (this time for 680news.com) presents responses to the speech from various interested parties,

According to popular Canadian astrologer Georgia Nicols, Canada’s Governor General should be doing what she can to “keep the peace” with loved ones today and avoid the “planetary vibe” that is urging people to engage in power struggles and disputes.

The advice, contained in Julie Payette’s Nov. 2 [2017] horoscope on Nicols’ website, might have come a day late, though Payette likely wouldn’t have listened to it anyway.

The Governor General made clear in a speech to scientists at an Ottawa convention Wednesday she has a very low opinion of the validity of horoscopes, people who believe in creationism or those who don’t believe in climate change.

…

Emmett Macfarlane, a political professor at the University of Waterloo said nothing stops a governor general from stating opinions and while there have been unwritten traditions against it, Payette’s most recent predecessors did not always hold their tongues.

…

Conservative political strategist Alise Mills said Payette went way over the line with her speech, which she characterized as not only political but “mean-spirited.”

“I definitely agree science is key but I think there is a better way to do that without making fun of other people,” Mills said.

There isn’t a lot of data on horoscope and astrology beliefs in Canada but a 2005 Gallup poll suggested around one in four Canadians believed in astrology.

…

Prime Minister Justin Trudeau didn’t seem to have any issue with what Payette said, saying his government and Canadians understand the value of science.

…

Mills said Payette wasn’t just promoting science, she was mocking people with religious beliefs, and specifically, evangelical Christians who don’t believe evolutionary science.

Astrologer Nicols said she had “no wish to take on a woman who is as accomplished as Julie Payette,” whom she notes is a “feisty Libra with three planets in Scorpio.”

But she did suggest Payette would be better to stick to what she knows.

“Astrology is not the stuff of horoscopes in newspapers, albeit I do write them,” wrote Nicols in an e-mail. “It is actually a complex study based on mathematics. Not fairy dust falling from the stars.”

There is one thing I find a bit surprising, Payette doesn’t seem to have taken on the vaccination issue. In any event, it looks like the conference had an exciting start.

Masterly science communication—treating your opponent with respect

There are many, many debates to be had about science, not least the debate about how one engages with individuals deemed to be practicing what has been called a ‘pseudo science’, in this case, astrology.  My focus here is on a response to how the debate was conducted and not on the merits of the arguments.

There was a recent kerfuffle about the cosmos shifting around so that the original 12 astrological signs in the zodiac of Western astrology were being displaced by the emergence of a 13th sign. You can read more about the announcement, which was made by astronomer (you read that correctly), Parke Kunkle, in the Jan. 13, 2011 news item in the Huffington Post.

At roughly the same time, there was a ruckus in the UK between astrologers and two astronomers who appear as presenters (hosts) of a BBC programme called, Stargazing. Astrologers were distressed by comments the presenters made about astrology and they wrote up a petition, which occasioned derision.

Apparently, the announcement and the ‘petition’ ruckus provided excuses for scientists, science writers, and science fans to heap scorn on and ridicule astrologers and the ‘pseudo science’ of astrology. It’s the same scornful attitude that proponents of emerging technologies often heap on individuals who are expressing an opinion or an idea usually based on fear about possible consequences.

One of the best responses I’ve seen to this ‘style’ of public debate is a Jan. 28, 2011 posting on Martin Robbins’ The Lay Scientist blog (one of the Guardian Science blogs). I’ve excerpted a few bits by  guest writer,Dr. Rebekah Higgitt, she’s responding to the astrologers’ BBC petition,

Like Martin, I heard about the astrologers’ petition to the BBC and blogged about it, together with another astrology-related story that recently hit the headlines. Unlike him, I was critical of the knee-jerk response of many scientists, science writers and fans of science. I also had some quibbles about his post, so I’d like to start by thanking him for hosting this – and, before you leap to the comments section, making it clear that I do not believe in astrology. However, I do believe that a little knowledge and understanding can help the cause of science communication far more than ridicule.

As is well known to readers of The Lay Scientist, the Astrological Association, prompted by remarks made by Brian Cox and Dara O’Briain, has asked for “fair and balanced representation” (note, not “equal representation”). This has resulted in widespread derision from those who can see nothing wrong with stating that “astrology is rubbish” and “nonsense”. Most, however, have failed to understand exactly what has annoyed these astrologers, or to take the time to find out what astrology actually is. [emphasis mine]

Note her emphasis on finding and understanding the basis of your ‘opponent’s’ ideas.

The Astrological Association is not complaining about a statement such as this. Rather, they consider it unfair that they are represented as having no knowledge of the astronomy and celestial mechanics that Cox and O’Briain are paid to explain on TV. They are annoyed that astrology is considered to consist solely of those who read and write newspaper horoscopes. Serious astrologers often have an excellent understanding of, and respect for, astronomy. [emphasis mine] They are, in fact, a not insignificant audience for astronomy programmes, lectures and books. This is why, as I explained in my earlier post, stories about “changing zodiac signs” and the “13th sign” Ophiucus do no one any favours. While Parke Kunkle’s “revelation” might confuse those with little knowledge of astrology or astronomy, it comes as no surprise to anyone else. The effect of precession has been understood for centuries, and practising astrologers are more than capable of dealing with this recurrent attack.

Which brings me to the history: a little historical understanding should make astronomers and science communicators realise that practising astrologers are likely to have good knowledge of planetary motions. Up until the late 17th century, astrology and astronomy were deeply interconnected. Since then there has been a parting of ways, but astrologers have continued to make use of accurate astronomical data. Astrology is not so much the father of positional astronomy and celestial mechanics as its client, patron and midwife.

Higgitt doesn’t believe in astrology (as she notes) but she extends a level of respect and courtesy that I have too rarely seen in discussions where a socially-defined expert group is effectively dismissing or accusing the other of being uninformed and/or superstitious and ridiculing them for their foolish beliefs and/or fears. By the way, Higgitt is Curator of History of Science and Technology, National Maritime Museum and Royal Observatory, Greenwich.
