Persistence of vision refers to the optical illusion whereby multiple discrete images blend into a single image in the human mind and believed to be the explanation for motion perception in cinema and animated films. Like other illusions of visual perception, it is produced by certain characteristics of the visual system.
Narrowly defined, the theory of persistence of vision is the belief that human perception of motion (brain centered) is the result of persistence of vision (eye centered). That version of the theory was disproved in 1912 by Wertheimer but persists in many citations in many classic and modern film-theory texts. A more plausible theory to explain motion perception (at least on a descriptive level) are two distinct perceptual illusions: phi phenomenon and beta movement.
A visual form of memory known as iconic memory has been described as the cause of this phenomenon. Although psychologists and physiologists have rejected the relevance of this theory to film viewership, film academics and theorists generally have not. Some scientists nowadays consider the entire theory a myth.
Persistence of vision is a theory on how the illusion of motion in films is achieved.

Persistence of Vision is a 2012 documentary film based on Richard Williams' experiences trying to get The Thief and the Cobbler made. The film was directed by filmmaker Kevin Schreck. Its tagline is, "the untold story of the greatest animated film never made." The film premiered in Canada on 4 October 2012 at the Vancouver International Film Festival.
Animator Richard Williams attempts to finish his masterpiece, a long-term vanity project called The Thief and the Cobbler. Though he did not participate in the making of the film, archival footage of Williams is combined with interviews with his co-workers.
Side (Greek: Σίδη) is an ancient Greek city on the southern Mediterranean coast of Turkey, a resort town and one of the best-known classical sites in the country. It lies near Manavgat and the village of Selimiye, 78 km from Antalya in the province of Antalya.
It is located on the eastern part of the Pamphylian coast, which lies about 20 km east of the mouth of the Eurymedon River. Today, as in antiquity, the ancient city is situated on a small north-south peninsula about 1 km long and 400 m across.
Strabo and Arrian both record that Side was founded by Greek settlers from Cyme in Aeolis, a region of western Anatolia. This most likely occurred in the 7th century BC. Its tutelary deity was Athena, whose head adorned its coinage.
Dating from the tenth century B.C., its coinage bore the head of Athena (Minerva), the patroness of the city, with a legend. Its people, a piratical horde, quickly forgot their own language to adopt that of the aborigines.
Possessing a good harbour for small-craft boats, Side's natural geography made it one of the most important places in Pamphylia and one of the most important trade centres in the region. According to Arrian, when settlers from Cyme came to Side, they could not understand the dialect. After a short while, the influence of this indigenous tongue was so great that the newcomers forgot their native Greek and started using the language of Side. Excavations have revealed several inscriptions written in this language. The inscriptions, dating from the 3rd and 2nd centuries BC, remain undeciphered, but testify that the local language was still in use several centuries after colonisation. Another object found in the excavations at Side, a basalt column base from the 7th century BC and attributable to the Neo-Hittites, provides further evidence of the site's early history. The name Side may be Anatolian in origin, meaning pomegranate.
Cue sports techniques (usually more specific, e.g., billiards techniques, snooker techniques) are a vital important aspect of game play in the various cue sports such as carom billiards, pool, snooker and other games. Such techniques are used on each shot in an attempt to achieve an immediate aim such as scoring or playing a safety, while at the same time exercising control over the positioning of the cue ball and often the object balls for the next shot or inning.
In carom games, an advanced player's aim on most shots is to leave the cue ball and the object balls in position such that the next shot is of a less difficult variety to make the requisite carom, and so that the next shot is in position to be manipulated in turn for yet another shot; ad infinitum.
Similarly, in many pocket billiards games, an advanced player's aim is to manipulate the cue ball so that it is in position to pocket (pot) a chosen next object ball and so that that next shot can also be manipulated for the next shot, and so on. Whereas in the carom games, manipulation of the object ball's position is crucial as well on every shot, in some pool games this is not as large a factor because on a successful shot the object ball is pocketed. However, many shots in one-pocket, for example, have this same added object ball control factor for most shots.
The terms A-side and B-side refer to the two sides of 78 and 45 rpm phonograph records, whether singles or extended plays (EPs). The A-side usually featured the recording that the artist, record producer, or the record company intended to receive the initial promotional effort and then receive radio airplay, hopefully, to become a "hit" record. The B-side (or "flip-side") is a secondary recording that has a history of its own: some artists, notably Elvis Presley, Little Richard, the Beatles, Chuck Berry, and Oasis, released B-sides that were considered as strong as the A-side and became hits in their own right. Creedence Clearwater Revival had hits, usually unintentionally, with both the B-sides of their A-side releases. Others took the opposite track: producer Phil Spector was in the habit of filling B-sides with on-the-spot instrumentals that no one would confuse with the A-side. With this practice, Spector was assured that airplay was focused on the side he wanted to be the hit side.

Everything is not as it first appears. This simple plastic ball looks purple until you swing it in a circle and reveal its true nature. Inside are three light emitting diodes (LEDs), which are red, green and blue. They turn on and off in sequence very quickly. When still, the ball appears purple because your eyes and brain don't 'refresh' quickly enough to perceive the changing colours. However, when swung in a circle, the ball changes colours at different locations so the colours don't merge with each other and the ball's true nature is revealed. Now let's not think too carefully about how this illusion is conveyed through video (because the camera doesn't refresh quickly enough to perceive the colours changing either - so you have no hope of seeing it on YouTube even frame by frame).

Peter Roger In 1824 Peter Roget introduced the concept of how the brain sees individual images as a sequence of motion. Persistence of vision is the phenomenon of the eye by which an afterimage is thought to persist for approximately one twenty-fifth of a second on the retina. According to the theory of persistence of vision, the perceptual processes of the brain or the retina of the human eye retains an image for a split second. This theory supposedly accounts for the fact that when a motion picture flashes a series of progressive images, instead of the mind seeing the flashing of a series of images, it sees the illusion of motion.

16 LED POV wand – we got PCB – fun persistence of vision part II In today’s video we are going to solder the POV wand PCB which was design by Ofer. After the soldering part I will cover the code and how to create new fonts. The system is built on Arduino Nano with 16 LEDS. Link to Part I https://youtu.be/B8S9hifINtk Port manipulation tutorial https://youtu.be/mJBBX46QwBU Link to the original instructable we used https://www.instructables.com/id/Arduino-Based-POV-Display-Stick-JolliPOV-Stick/ Link to tutorial on the GLCD font creator http://www.georgegardner.info/arduino/easy-font-creation-for-led-matrix-from-truetype-system-fonts.html
The green hands aim at a target at the top of the screen, while avoiding the black obstacles. The actual state of the system is uncertain, and the eye provides local disambiguation of the "real" state. I also model visual inhibition during saccades - the disambiguation is inversely proportional to the eye's velocity, so the eye provides no useful information when it is in fast motion. The system is formulated as a stochastic optimal control problem, solved using differential dynamic programming over an augmented state space (representing the distribution in the real state space as a single Gaussian, estimated using the Kalman filter).

We will present BloombergGPT, a 50 billion parameter language model, purpose-built for finance and trained on a uniquely balanced mix of standard general-purpose datasets and a diverse array of financial documents from the Bloomberg archives. Building a large language model (LLM) is a costly and time-intensive endeavor. To reduce risk, we adhered closely to model designs and training strategies from recent successful models, such as OPT and BLOOM. Nevertheless, we faced numerous challenges during the training process, including loss spikes, unexpected parameter drifts, and performance plateaus. In this talk, we will discuss these hurdles and our responses, which included a complete training restart after weeks of effort. Our persistence paid off: BloombergGPT ultimately outperformed exist...
