“We often plough so much energy into the big picture, we forget the pixels”*…
Alvy Ray Smith (see also here) was born before computers, made his first computer graphic in 1964, cofounded Pixar, was the first director of computer graphics at Lucasfilm, and the first graphics fellow at Microsoft. He is the author of the terrific new book A Biography of the Pixel (2021), from which, this excerpt…
I have billions of pixels in my cellphone, and you probably do too. But what is a pixel? Why do so many people think that pixels are little abutting squares? Now that we’re aswim in an ocean of zettapixels (21 zeros), it’s time to understand what they are. The underlying idea – a repackaging of infinity – is subtle and beautiful. Far from being squares or dots that ‘sort of’ approximate a smooth visual scene, pixels are the profound and exact concept at the heart of all the images that surround us – the elementary particles of modern pictures.
This brief history of the pixel begins with Joseph Fourier in the French Revolution and ends in the year 2000 – the recent millennium. I strip away the usual mathematical baggage that hides the pixel from ordinary view, and then present a way of looking at what it has wrought.
The millennium is a suitable endpoint because it marked what’s called the great digital convergence, an immense but uncelebrated event, when all the old analogue media types coalesced into the one digital medium. The era of digital light – all pictures, for whatever purposes, made of pixels – thus quietly began. It’s a vast field: books, movies, television, electronic games, cellphones displays, app interfaces, virtual reality, weather satellite images, Mars rover pictures – to mention a few categories – even parking meters and dashboards. Nearly all pictures in the world today are digital light, including nearly all the printed words. In fact, because of the digital explosion, this includes nearly all the pictures ever made. Art museums and kindergartens are among the few remaining analogue bastions, where pictures fashioned from old media can reliably be found…
An exact mathematical concept, pixels are the elementary particles of pictures, based on a subtle unpacking of infinity: “Pixel: a biography,” from @alvyray.

As we ruminate on resolution, we might recall that it was on this date in 1947 that fabled computer scientist Grace Hopper (see here and here), then a programmer at Harvard’s Harvard’s Mark II Aiken Relay computer, found and documented the first computer “bug”– an insect that had lodged in the works. The incident is recorded in Hopper’s logbook alongside the offending moth, taped to the logbook page: “15:45 Relay #70 Panel F (moth) in relay. First actual case of bug being found.”
This anecdote has led to Hopper being pretty widely credited with coining the term “bug” (and ultimately “de-bug”) in its technological usage… but the term actually dates back at least to Thomas Edison…

Argument over a Card Game by Jan Steen
Before people had an image, they had their honour. For much of history, little was more valuable than individual honour. ‘Better to die 10,000 deaths than wound my honour,’ as a character in Joseph Addison’s Cato, A Tragedy (1712) put it. In his bestselling Of Domesticall Duties (1622), William Gouge declared: “a good name is a most pretious thing.”
Despite the persistence of the word and a loosely related idea, the concept of honour, as earlier eras understood it, is so foreign to moderns that it can be hard to grasp. A stereotyped account holds that in early modern England a man’s honour was associated with a willingness to use violence to defend his name, while for women honour was about the maintenance of a proper sexual reputation.
But this is a very thin and misleading idea of honour in early modern England. Personal letters and diaries of elites indeed reveal a preoccupation with honour, a sense of its almost inestimable value. They also reveal that honour wasn’t just about violence among elite men or sexual propriety among elite women. Honour concerned one’s whole person. Likewise, it was less a static, overarching code of behaviour than a loosely defined concept with an array of meanings that could be variously privileged, one over another, with fluidity depending upon the needs and objectives of an individual in a given situation…
On the complicated business of living an honorable life: “The early moderns had their work cut out curating their honour.”

As we wax nostalgic for a time when honor mattered most, we might send conflicted birthday greetings to a man whose life illustrated the early modern to modern transition from honor to image; Fritz Haber was born on this date in 1868. The recipient of the Nobel Prize in Chemistry in 1918 for his invention of the Haber–Bosch process, a method used in industry to synthesize ammonia from nitrogen gas and hydrogen gas– thus enabling the production of more, more affordable, and more effective fertilizers, which in turn allowed millions to avoid starvation– Haber is equally well known as the Father of Chemical Warfare for his pioneering work developing and weaponizing chlorine and other poisonous gases during World War I, especially his actions during the Second Battle of Ypres.
