“Time flies like an arrow; fruit flies like a banana”*…
A companion of a sort to last Friday’s post: In the 19th century, the linear idea of time became dominant. As Emily Thomas explains, that has had profound implications for how we experience the world…
‘It’s natural,’ says the Stanford Encyclopedia of Philosophy, ‘to think that time can be represented by a line.’ We imagine the past stretching in a line behind us, the future stretching in an unseen line ahead. We ride an ever-moving arrow – the present. However, this picture of time is not natural. Its roots stretch only to the 18th century, yet this notion has now entrenched itself so deeply in Western thought that it’s difficult to imagine time as anything else. And this new representation of time has affected all kinds of things, from our understanding of history to time travel.
Let’s journey back to ancient Greece. Amid rolls of papyrus and purplish figs, philosophers like Plato looked up into the night. His creation myth, Timaeus, connected time with the movements of celestial bodies. The god ‘brought into being’ the sun, moon and other stars, for the ‘begetting of time’. They trace circles in the sky, creating days, months, years. The ‘wanderings’ of other, ‘bewilderingly numerous’ celestial bodies also make time. When all their wanderings are ‘completed together’, they achieve ‘consummation’ in a ‘perfect year’. At the end of this ‘Great Year’, all the heavenly bodies will have completed their cycles, returning to where they started. Taking millennia, this will complete one cycle of the universe. As ancient Greek philosophy spread through Europe, these ideas of time spread too. For instance, Greek and Roman Stoics connected time with their doctrine of ‘Eternal Recurrence’: the universe undergoes infinite cycles, ending and restarting in fire.
Such views of time are cyclical: time comprises a repeating cycle, as events occur, pass, and occur again. They echo processes in nature. Day and night. Summer to winter. As the historian Stephen Jay Gould explains in Time’s Arrow, Time’s Cycle (1987), within the West, cyclical conceptions dominated ancient thought. It’s even hinted at in the Bible. For example, Ecclesiastes proclaims: ‘What has been will be again … there is nothing new under the sun.’ Yet, Gould writes, the Bible also contains a linear conception of time: time comprises a one-way sequence of unrepeatable events. Take Biblical history: ‘God creates the earth once, instructs Noah to ride out a unique flood in a singular ark.’ Gould describes this linear understanding of history as an ‘important and distinctive’ contribution of Jewish thought. Biblical history helped power linear ideas of time.
Cyclical and linear conceptions of time thrived side by side for centuries, sometimes blurring into one another. After all, we live through natural, cyclical seasons and unrepeatable events – birth, first marriage, death. Importantly, medievals and early moderns didn’t literally see cyclical time as a circle, or linear time as a line. Yet in the 19th-century world of frock coats, petticoats and suet puddings, change was afoot. Gradually, the linear model of time gained ground, and thinkers literally began drawing time as a line…
[Thomas explores four key developments that fueled the shift, chronography (the development of timelines), Darwin and the emergence of the concept of evolution, chronophotography, and theories in math and physics of a “fourth dimension” (then explored by Einstein and Bergson, Mary Calkins and Victoria Welby, Bertrand Russell, H. G. Wells, and so many others…]
… Today, conceiving of time as a line remains widespread. Timelines are everywhere: in the history of evolution, the history of video games, and the history of chocolate. There’s even a timeline of timelines. And the effects of this line of thought (pun intended) are still with us. Philosophers continue to debate the reality of past and future: just check out this bumper encyclopaedia article on ‘Presentism’, ‘the view that only present things exist’. Time-travel stories run rife. Back to the Future. Groundhog Day. The Time Traveler’s Wife. Historians have largely dropped Victorian faith in the progress of humanity, yet progress stories about particular areas remain. For example, take this timeline: it straightforwardly depicts technological progress over time. All these ideas are powered by the notion that time is a line. Were we to reshape our idea of time, perhaps these other ideas would also find themselves bent into new forms…

As we wonder at Yeat’s widening gyre, we might send echoing birthday greetings to Charles Louis de Secondat, baron de La Brède et de Montesquieu; he was born on this date in 1689. Better known simply as Montesquieu, he was a French judge, historian, and political philosopher.
Montesquieu is the principal source of the theory of separation of powers, which is implemented (if not always observed) in many constitutions throughout the world. He is also known for doing more than any other author to secure the place of the word “despotism” in the political lexicon. His anonymously published The Spirit of Law (De l’esprit des lois, 1748; first translated into English in 1750) was received well in both Great Britain and the American colonies, and influenced the Founding Fathers of the United States in drafting the U.S. Constitution.
“History is not the past but a map of the past, drawn from a particular point of view, to be useful to the modern traveler”*…
Timelines are now a commonplace. But as Emily Thomas explains, Joseph Priestley’s “A New Chart of History” revolutionized how we view history…
… Priestley (1733-1804) is best known for his scientific work, especially the co-discovery of oxygen. Yet he was also a teacher and a philosopher. As a teacher, Priestley sought to better communicate history to his students. He was fascinated by chronologies, texts ordering events. Since ancient Greece and Rome, chronologers used ‘time tables’ or grids to depict the order of events in time. An obvious problem with these chronologies, though, is that only so many events can fit on each page.
The mid-18th century saw many experiments in representing history, including Thomas Jefferys’ 1753 A Chart of Universal History. Jefferys was a mapmaker and his chart depicts empires almost as though they are countries on a map, allowing you to scan them all at once. Impressed, Priestley determined to create a chart of his own that readers could scan ‘at one view’. He made several innovations but one proved key: lines, inspired by his philosophy of time.
For this, Priestley drew on a seemingly unconnected topic: John Locke’s 1690 account of abstract ideas. For Locke, abstract ideas include ‘redness’, ‘triangle’, or ‘animal’. They are general ideas, produced when our minds consider particular things. Take a pint of milk, a stick of chalk and a lump of snow. I can consider these things while leaving out their particular features, ‘abstracting’ what is common to them: their whiteness. Many philosophers accepted some version of Locke’s account of abstraction, but puzzled over how to mentally visualise them. Locke writes that our abstract idea of a triangle ‘must be neither Oblique, nor Rectangle, neither Equilateral, Equicrural, nor Scalenon; but all and none of these at once’. Clearly we cannot picture such a thing. Priestley makes an alternative suggestion: represent abstract ideas using a variable particular. A child, he writes, has an idea of ‘what a triangle in general is’, even though all the ideas of triangles he ‘contemplates’ are ‘particular’. In other words, our picture of the abstract idea of a triangle can change: from equilateral to, say, scalene. In the same essay, Priestley argued that time is an abstract idea. And this view feeds into his timeline…

As we ponder the past, we might send evocative birthday greetings to Jules Michelet; he was born on this date in 1798. Considered one of the founders of modern historiography, he is best known for his multivolume work Histoire de France (History of France).
Influenced by Giambattista Vico, Michelet emphasized on the role of people and their customs in shaping history, a major departure from the then-current emphasis on political and military leaders. He coined the term “Renaissance” (meaning “rebirth” in French) as a period in Europe’s cultural history that represented a break from the Middle Ages, creating a modern understanding of humanity and its place in the world. (The term “rebirth” and its association with the Renaissance can be traced to a work published in 1550 by the Italian art historian Giorgio Vasari. Vasari used the term to describe the advent of a new manner of painting that began with the work of Giotto, as the “rebirth (rinascita) of the arts.”)
“Some historians hold that history is just one damned thing after another”*…
… and in one sense, it is. From Matan Stauber, a remarkable demonstration…
“Histography” is interactive timeline that spans across 14 billion years of history, from the Big Bang to 2015.
The site draws historical events from Wikipedia and self-updates daily with new recorded events.
The interface allows for users to view between decades to millions of years.
The viewer can choose to watch a variety of events which have happened in a particular period or to target a specific event in time. For example you can look at the past century within the categories of war and inventions…

As we connect the dots, we might send well-preserved birthday greetings to Kevin Brownlow; he was born on this date in 1938. A filmmaker (documentarian and editor), he is best known as a film historian– the film historian of the Silent Era. His initiative in interviewing many largely forgotten, elderly film pioneers in the 1960s and 1970s preserved a legacy of early mass-entertainment cinema. He received an Academy Honorary Award at the 2nd Annual Governors Awards given by the Academy of Motion Picture Arts and Sciences on 13 November 2010– the first time an Academy Honorary Award was given to a film preservationist.

As Niels Bohr said, “prediciton is hard, especially about the future.” Still, we can try…
While the future cannot be predicted with certainty, present understanding in various scientific fields allows for the prediction of some far-future events, if only in the broadest outline. These fields include astrophysics, which studies how planets and stars form, interact, and die; particle physics, which has revealed how matter behaves at the smallest scales; evolutionary biology, which studies how life evolves over time; plate tectonics, which shows how continents shift over millennia; and sociology, which examines how human societies and cultures evolve.
The far future begins after the current millennium comes to an end, starting with the 4th millennium in 3001 CE, and continues until the furthest reaches of future time. These timelines include alternative future events that address unresolved scientific questions, such as whether humans will become extinct, whether the Earth survives when the Sun expands to become a red giant and whether proton decay will be the eventual end of all matter in the Universe…
A new pole star, the end of Niagara Falls, the wearing away of the Canadian Rockies– and these are just highlights from the first 50-60 million years. Read on for an extraordinary outline of what current science suggests is in store over the long haul: “Timeline of the far future,” a remarkable Wikipedia page.

As we take the long view, we might send grateful birthday greetings to the man who “wrote the book” on perspective (a capacity analogically handy in the endeavor featured above), Leon Battista Alberti; he was born on this date in 1404. The archetypical Renaissance humanist polymath, Alberti was an author, artist, architect, poet, priest, linguist, philosopher, cartographer, and cryptographer. He collaborated with Toscanelli on the maps used by Columbus on his first voyage, and he published the the first book on cryptography that contained a frequency table.
But he is surely best remembered as the author of the first general treatise– De Pictura (1434)– on the the laws of perspective, which built on and extended Brunelleschi’s work to describe the approach and technique that established the science of projective geometry… and fueled the progress of painting, sculpture, and architecture from the Greek- and Arabic-influenced formalism of the High Middle Ages to the more naturalistic (and Latinate) styles of Renaissance.

March 12, 1989 Information Management, a Proposal
While working at CERN, Tim Berners-Lee first comes up with the idea for the World Wide Web. To pitch it, he submits a proposal for organizing scientific documents to his employers titled “Information Management, a Proposal.” In this proposal, Berners-Lee sketches out what the web will become, including early versions of the HTTP protocol and HTML.

As we jack in, we might recall that it was on this date in 1969 that the world first learned of what would become the internet, which would, in turn, become that backbone of the web: UCLA announced it would “become the first station in a nationwide computer network which, for the first time, will link together computers of different makes and using different machine languages into one time-sharing system.” It went on to say that “Creation of the network represents a major forward step in computer technology and may server as the forerunner of large computer networks of the future.”
UCLA will become the first station in a nationwide computer network which, for the first time, will link together computers of different makes and using different machine languages into one time-sharing system.
Creation of the network represents a major forward step in computer technology and may serve as the forerunner of large computer networks of the future.
The ambitious project is supported by the Defense Department’s Advanced Research Project Agency (ARPA), which has pioneered many advances in computer research, technology and applications during the past decade. The network project was proposed and is headed by ARPA’s Dr. Lawrence G. Roberts.
The system will, in effect, pool the computer power, programs and specialized know-how of about 15 computer research centers, stretching from UCLA to M.I.T. Other California network stations (or nodes) will be located at the Rand Corp. and System Development Corp., both of Santa Monica; the Santa Barbara and Berkeley campuses of the University of California; Stanford University and the Stanford Research Institute.
The first stage of the network will go into operation this fall as a subnet joining UCLA, Stanford Research Institute, UC Santa Barbara, and the University of Utah. The entire network is expected to be operational in late 1970.
Engineering professor Leonard Kleinrock [see here], who heads the UCLA project, describes how the network might handle a sample problem:
Programmers at Computer A have a blurred photo which they want to bring into focus. Their program transmits the photo to Computer B, which specializes in computer graphics, and instructs B’s program to remove the blur and enhance the contrast. If B requires specialized computational assistance, it may call on Computer C for help.
The processed work is shuttled back and forth until B is satisfied with the photo, and then sends it back to Computer A. The messages, ranging across the country, can flash between computers in a matter of seconds, Dr. Kleinrock says.
UCLA’s part of the project will involve about 20 people, including some 15 graduate students. The group will play a key role as the official network measurement center, analyzing computer interaction and network behavior, comparing performance against anticipated results, and keeping a continuous check on the network’s effectiveness. For this job, UCLA will use a highly specialized computer, the Sigma 7, developed by Scientific Data Systems of Los Angeles.
Each computer in the network will be equipped with its own interface message processor (IMP) which will double as a sort of translator among the Babel of computer languages and as a message handler and router.
Computer networks are not an entirely new concept, notes Dr. Kleinrock. The SAGE radar defense system of the Fifties was one of the first, followed by the airlines’ SABRE reservation system. At the present time, the nation’s electronically switched telephone system is the world’s largest computer network.
However, all three are highly specialized and single-purpose systems, in contrast to the planned ARPA system which will link a wide assortment of different computers for a wide range of unclassified research functions.
“As of now, computer networks are still in their infancy,” says Dr. Kleinrock. “But as they grow up and become more sophisticated, we will probably see the spread of ‘computer utilities’, which, like present electronic and telephone utilities, will service individual homes and offices across the country.”
