Joseph Antoine Ferdinand Plateau was a famous Belgian physicist and mathematician who is the first inventor of phenakistiscope. His research on visual perception laid the foundations of film.
Where the Joseph Antoine Ferdinand Plateau born?
Joseph Antoine Ferdinand Plateau was born in Brussels, Belgium (14 October 1801-September 1883) and was a prominent physicist. The first people to display the illusion of moving pictures made him known. In small increment motions of repeated images on one and equally divided between the images, Joseph Plateau employed counter-rotating discs.
In 1832 he called this apparatus phenakistiscope. The phenakistiscope was soon sold as a toy and a cylindrical drum was introduced instead of a disk.
Who is the father of Plateau?
Joseph Antoine Ferdinand Plateau was Joseph Anthony’s father and was born on the Plateau of Joseph Anthony, Tournay. When he was still the age of six, he could already read it. When he was just 14 years old, his father and mother were dead and he became sick with the trauma. He was more interested in the physics class at primary school and the interest in experiments was increased considerably.
He went to school in Marche-Les-Dames with his uncle. When he graduated from high school Plateau took an interest in science, but at the University of Liège, his uncle would like to study law. At the time, Plateau wanted to research science.
Just before the war broke out in 1815, Joseph Plateau moved to a village near Waterloo. He fled into the forest with his siblings, and he later wrote about the hunting of butterflies in that forest.

When Plateau School as a Teacher
As a mathematics teacher in Brussels, she is joining an Atheneum college. He graduated from the University of Liege in 1829 with a Ph.D. in Mathematics and Physics. In 1829, the plateau experimented with sunlight for over 25 seconds, and for several days he was blind.
He also saw vivid halos around light sources for many years since. He began torment by the symptom illness in 1841 and just two years he became completely blind. Plateau was called to the University of Ghent in 1835 as Professor of Physics and Applied Physics.
When Joseph Antoine Ferdinand Plateau got married?
The son was born one year later, on August 27, 1840, and Joseph Plateau married Augustine–Thérèse–Aimée–Fanny Clavareau. In 1872, Plateau became an Academy of Arts and Sciences part of the Royal Netherlands.
He died in Ghent, Belgium, on September 15, 1883. It was 81 when.
Joseph Antoine Ferdinand Plateau: Who was the Belgian physicist known as the ‘father of film’?
The birthday of Joseph Ferdinand Plateau, the Belgian physicist who has been identified before as the “father of film” is celebrated by Google.
But who was Joseph Antoine Ferdinand Plateau, and how did that illustrious title come about?
Plateau was born in Brussels in 1801, the son of an artist who specialized in flowers.
Identified as a young “prodigy,” he developed a strong interest in physics at an early age and started to invent many instruments while still at school by his boy-in-law and biographer Gustaaf Van der Mensbrugghe.
Although he was studying law at first, his experiments in the home continued – an exploit which often destroyed his furniture and, according to Van der Mensbrugghe, almost poisoned him with toxic gas on one occasion.
Eventually, Plateau’s doctoral thesis would be the foundation for a seminal moment in science and arts if he turned his academic attention on science.
His dissertation from 1829 dealt with the form of pictures of the retina and detailed Plateau’s exact color, time, and strength.
He rendered the first-ever moving image of what is known as a phenakistoscope three years later, through this study.
The phenakistoscope was a tool comprising two rotational disks, one equipped with small windows with a series of photographs of a dancer, moving in the opposite direction.
“The images seemed to merge with each disk to create the illusion of a dancer in motion when they were turned exactly right,” Google said.
Phenakistiscopes were widely sold in Europe and then, with images of horses, Eadweard Muybridge creates a common variation of the device which produces probably the first example of halt movement.
As Joseph Antoine Ferdinand Plateau innovation paved the way for contemporary cinema, it may have cost him his obsession with light and sight.
The scientist is said to have conducted a 25-second experiment with the sun to better understand the effects of light on the retina.
Although he is claimed to have blamed this experiment on his failing vision, others think that he may have had chronic uveitis.
However, his scientific work had not prevented his loss of vision, and he would make a variety of significant observations, including in surface tension – fluid tending to shrink to the smallest possible surface area.
Joseph Plateau’s spinning disc illusions were the forerunner of cinema
The Belgese physicist Joseph Antoine Ferdinand Plateau laid the foundations for film, television, and animated gifs with his study of visual perception. He invented a phenakistiscope system that created the illusion of a moving picture and today is portrayed in Google’s doodle on its 218th birthday.
At the age of 14, he had lost both his parents. Soon before the war broke out in 1815, Plateau moved to a village near Waterloo. He fled into the forest with his siblings, and he later wrote about the hunting of butterflies in that forest.
Plateau developed a high school science interest, but his uncle insisted on him studying law at the University of Liège. Plateau decided at the same time he was going to study science.
Plateau stated in his thesis on the persistence of visual experiences, which causes us to see falling rainfall as lines or a vibrating string as a static bend in it. It clarified that if you look through a split in a mirror to a disk reflection, a spinning disc with slits around the edge appears motionless. The observer could perceive a moving drawing by adding drawings to the disk.
It was easily sold as a toy – the phenakistoscope. A cylindrical drum instead of a disk was also available in another version.

Plateau stared straight at the sun for 25 seconds and was blind for several days in 1829, the year he completed his studies. He also saw brightly colored halos around light sources for years afterward.
In 1841 he started to suffer from the effects of a disease that in two years would lead to his complete blindness. Choroiditis – the inflammation of the choroidal layer behind the eye retina – was diagnosed and the disease was due to sunscreening by Plateau. But modern ophthalmologists agree that it may not have been linked and may be caused by an immune system problem.
He kept reading and writing articles, teaching new science experts to watch phenomena that he couldn’t see himself anymore.
JOSEPH PLATEAU’S SOAPY OBSERVATIONS FIRST DEFINED “PATTERNS IN NATURE”
On Monday, Google Doodle, a man of art, science, and innovation, was Joseph Antoine Ferdinand Plateau. Plateau’s interests led him in many directions, from the fan fast development of a moving imaging system called the phénakistiscope, to his deeper ruminations about the essence of the physical universe, as illustrated in the doodle today.
As a physicist, he is also known for his contributions to our knowledge of one of the most enigmatic geometries in the world, the soap bubble.
While soap bubbles could seem unassuming, Plateau believes that they were wonderful because, according to a medium pot on the findings, they almost universally form perfectly tight, spherical formations with each occurrence.
In the experimental period 1842 to 1868, first of all in the oil “bubble” suspended in a solution of water and alcohol, then in a bubble wandlike experiment in which sphere-shaped wire figures are submerged in a solution of soap and flue Glycerol before they are raised to form thin, bubbly membranes. This physical phenomenon has been aroused by Plateau.
If it is becoming familiar this may be because such bubble experimentations are also an integral part of almost all the children’s museums and, at some point in time in the past, you were possibly attempting to replicate Plateau experiments with your sneakers in a bubble solution.
Joseph Antoine Ferdinand Plateau draws universal conclusions from his various observations and 80-odd bubble contractions on bubble membranes and what they described as something mathematicians call minimal surfaces — surfaces that naturally take on low surface energies and tension to preserve their thin surface areas.
This also implies, in the case of a soap bubble, that the surface has a small area that can absorb the sphere volume.
PLATEAU’S LAWS ON MINIMAL SURFACE GEOMETRIES (AKA SOAP BUBBLES)
- Soap film consists of smooth surface elements.
- Each aspect of a soap film is constantly in mean curvature.
- Soap films link with the arch (−1/2) = 120° in the curves.
- In groups of four, at vertices with arccos angles (−1/3) − 109.5 °, these curves meet. Plateau’s inquiry into soap bubbles and, on the other hand, minimal areas goes beyond pure curiosity – albeit what is generated – and has found its place in computer graphics, theoretical mathematics, and architectural studies as well as in the natural world in different types of natural embodiment.
SCIENTISTS DETECT ANCIENT COSMIC ‘BACKGROUND NOISE’ HIDDEN IN OLD ARECIBO OBSERVATORY DATA
A team of astronomers over 13 YEARS detected signals from spinning stars to catch faint space-time ribs called gravitational waves.
Finally, the first low-frequency gravitational waves that are ever observed could have been discovered.
The assertion was made by the North American Nanohertz Gravitational-Wave Observatory team (NANOGrav), which said that they discovered a weak signal caused by the first low-frequency gravity waves. These are strikingly data from the Arecibo Observatory, which is now gone.
The latest observation is detailed in a report in The Astrophysical Journal of January, and it has important repercussions for how we observe — or hear — the universe.
HERE’S THE BACKGROUND
The first signal detection from gravitational waves was made on 15 September 2015 by researchers. The signal was the result of the fusion of two black trousers that crashed 1.3 billion years ago.
The accelerated masses of celestial beings allow the gravitational waves to send out waves at the speed of light. When astronomers can see the world by electromagnetic radiation or light, gravitational waves are a way to hear the universe.
Scientists can detect the signal produced by these waves through laser interferometer gravitational wave (LIGO) detectors and Virgo detectors.
The gravitational waves are relatively small as they hit the Earth and last a few seconds. Scientists study the signals and locate the origins of the gravity waves and listen to the early universe happenings.
The bulk of the events that the detectors capture are caused by two black hole collisions.
LOW-FREQUENCY GRAVITATIONAL WAVES
For billions of years, they have been formed by many black troughs that circle each other and emanate signals that have far longer wavelengths.
Low-frequency gravitational waves are more persistent background noise compared to their high-frequency counterparts.
Consequently, years of data are needed to be identified.
HOW THEY DID IT — NANOGrav
It consists of over 100 astronomers from all over the United States and Canada who are united to detect low-frequency gravitational waves in a single attempt.
To make the discovery, the astronomers used a kind of star called a pulsar. Pulsars are small stars with a high magnetic field and spin with an electromagnetic beam. Often scientists use the pulsars as “cosmic lighthouses” due to their special qualities.
Pulsar stars are known as the timekeepers of the universe, which emit light periodically. According to the report, any irregularity in that schedule may have been caused by the spacetime expanding and diminishing gravitational waves.
The waves produced by gravity waves create small variations in the time predicted to occur on Earth, which means that Earth’s location has changed.
Researchers have detected a group of pulsars using Puerto Rico’s Arecibo Observatory that crashed in December 2020 and ended as one of the world’s largest radio telescopes.
They calculated the signal time of the pulsars distributed in the sky, a method called the “pulsar timing array,” which was simultaneously emitted, and were able to detect minute shifts in the direction of Earth from the stars.
WHAT THEY FOUND
This is the strongest signal of a gravitational wave at low frequency. The scientists also can’t agree that a low-frequency gravitational wave signal is causing minute shifts. But other options, such as interference from other matter in the solar system, were ruled out.
Joseph Simon, a NANOGrav member and the lead researcher in this report, said in an address: “It is extremely exciting to see such a clear sign emerging from the results.
“We must carefully understand our noise, however, because we are searching for gravitational waves throughout our observations,” he says.
“Some of the noise sources we have identified can be strongly excluded, but we cannot yet tell if the message is really from gravitational waves.
