“Earth is a small town with many neighborhoods in a very big universe”*…

… full of very large objects. From @nealagarwal, a scroll-able comparison of the size of the objects that surround us in in the universe: “Size of Space.”

As we internalize insignificance, we might send distantly-observed birthday greetings to Harlow Shapley; he was born on this date in 1885. An astronomer known as “the Modern Copernicus,” he did important work first at the Mt. Wilson Observatory, and then as head of the Harvard College Observatory. He boldly and correctly proclaimed that the globulars outline the Galaxy, and that the Galaxy is far larger than was generally believed and centered thousands of light years away in the direction of Sagittarius: he discovered of the center of our Galaxy, and of our position within it.

“The greatest value of a picture is when it forces us to notice what we never expected to see”*…

Detail from Richard Waller’s “Tabula colorum physiologica …” [Table of physiological colours], from Philosophical Transactions, 1686 — Source.

One of the most demanding challenges for early modern scientists was devising how best to visually portray their discoveries to the public. In the absence of any sort of technology for automatic visualisation, like cameras or scanners, the sixteenth- and seventeenth-century natural philosopher had to rely on drawings and subsequently woodcuts, etchings, or engravings to turn an experimental finding into a reproducible and publicly accessible demonstration. This was a laborious, expensive, time-consuming, and often problematic operation. Negotiated between several parties involved in the world of image-making, such as draughtsmen, engravers, and printers, the results were inevitably compromises between the intentions of the researcher and the possibilities of the printing press. For example, what a drawing could express with shading, washing, and chromatic nuances, printed illustrations could only approximate through a binary system of black and white, resulting from the pressure of an inked copper plate against a page.

The problem of efficient imaging was particularly felt during the early years of the Royal Society, a scientific institution founded in London in the early 1660s and today still regarded as one of the most prestigious institutions of scientific research in the world. In its early decades of activity, the Royal Society established itself as one of the central forces of the Scientific Revolution, with renowned members such as Robert Boyle and Isaac Newton. Members of the Society used to meet on a weekly basis to discuss ongoing research on a variety of subjects, such as physics, mathematics, biology, astronomy, mechanics, geography, and antiquarianism.

Soon after its foundation, the Royal Society sought new ways to increase visibility and maximise its public reach. From this emerged the Philosophical Transactions, a monthly peer-reviewed journal, the first of its kind, featuring extracts from the Royal Society’s weekly research meetings. Founded in 1665 by the Society’s Secretary Henry Oldenburg and still published to this day, the Transactions are regarded as the first and longest-running scientific journal in history, as contributions were the result of original explorative studies into natural and mechanical matters informed by the Society’s culture of experiment — part of what today we generally call science.

The Transactions were printed in small quarto format (about 17x22cm) with up to about a dozen articles per issue and could be purchased for the price of one shilling, about £5 today. The journal was a pioneering learned publication, with exceptional frequency and aimed at a diverse public of curious researchers. As such, especially in the early years, its contributors were often preoccupied with how best to communicate their ideas and discoveries through the immediacy of mass-producible visual media. A closer look into a selection of these articles demonstrates the extent to which natural philosophers were prepared to re-invent the production and consumption of images with new and often odd strategies for representing the world. This was a process of endless hands-on experimentation, often pushing beyond the traditional confines of the printing house…

From infographics to digital renders, today’s scientists have ready access to a wide array of techniques to help visually communicate their research. It wasn’t always so: “‘More Lively Counterfaits’– Experimental Imaging at the Birth of Modern Science.”

As we “show don’t tell,” we might spare a thought for Earle Dickson; he died on this date in 1961.  Dickson, concerned that his wife, Josephine Knight, often cut herself while doing housework and cooking, devised a way that she could easily apply her own dressings.  He prepared ready-made bandages by placing squares of cotton gauze at intervals along an adhesive strip and covering them with crinoline.  In the event, all his wife had to do was cut off a length of the strip and wrap it over her cut.  Dickson, who worked as a cotton buyer at Johnson & Johnson, took his idea to his employer… and the Band-Aid was born.

As we celebrate clarity, we might spare a thought for the mathematician, biologist, historian of science, literary critic, poet, and inventor Jacob Bronowski; he died on this date in 1974.  Bronowski is probably best remembered as the writer (and host) of the epochal 1973 BBC television documentary series (and accompanying book), The Ascent of Man (the title of which was a play on the title of Darwin’s second book on evolution, The Descent of Man)… the thirteen-part series, a survey of the history of science–  from rock tools to relativity– and its place in civilizations, is still an extraordinary treat.  It’s available at libraries, on DVD, or (occasionally) on streaming services.

As we wonder if enough is ever enough, we might spare a thought for one of the architects of the economic reality in which we live, Gary Becker; he died on this date in 2014.  A Nobel laureate economist with an interest in the social sciences, Becker updated the concept of “human capital” (which dated, of course, back to the days of Adam Smith and slavery), arguing that labor economics is part of capital theory.  He mused that “economists and plan-makers have fully agreed with the concept of investing on human beings.”  In this and other assertions, he was a defining proponent of the Chicago school of economics.

“Enumeration shall be made within three Years after the first Meeting of the Congress of the United States, and within every subsequent Term of ten Years, in such Manner as they shall by Law direct.”*…




The census is an essential part of American democracy. The United States counts its population every ten years to determine how many seats each state should have in Congress. Census data have also been used to levy taxes and distribute funds, estimate the country’s military strength, assess needs for social programs, measure population density, conduct statistical analysis of longitudinal trends, and make business planning decisions.

We looked at every question on every census from 1790 to 2020. The questions—over 600 in total—tell us a lot about the country’s priorities, norms, and biases in each decade. They depict an evolving country: a modernizing economy, a diversifying population, an imperfect but expanding set of civil and human rights, and a growing list of armed conflicts in its memory…

From our friends at The Pudding (@puddingviz), a graphic history of the questions asked in the U.S. Census. What changes each decade, what stays the same, and what do the questions say about American culture and society? “The Evolution of the American Census.”

For a look at how the pandemic is impacting this year’s census, see “It’s the Official Start to the 2020 Census. But No One Counted On a Pandemic.” and “Coronavirus could exacerbate the US census’ undercount of people of color.”

* Article 1, Section 2, of the the Constitution of the United States of America, directing the creation and conducting of a regular census; Congress first met in 1789, and the first national census was held in 1790.


As we answer faithfully, we might send illustratively enumerating birthday greetings to John James Audubon; he was born on this date in 1785.  An ornithologist, naturalist, and artist, Audubon documented all types of American birds with detailed illustrations depicting the birds in their natural habitats.  His The Birds of America (1827–1839), in which he identified 25 new species, is considered one of the most important– and finest– ornithological works ever completed.
