Early pioneer of experimental and founder of psychophysics, he inspired many scientists and of ⁡ the 20th century. that became known as the Weber-Fechner Law. Fechner's early life and scientific career were born in Grosh-Schurchen, near Muskau, in , where his father was a pastor. Although Fechner was raised by his religious father, he became an atheist in later life. He was first educated in Sorau (now Dawn in Western ). In 1817 he studied medicine at Medizinische Akademie by Carl Gustav Karus in Dresden and since 1818 at the University of Leipzig, the city in which he spent the rest of his life. In 1835 he received his doctorate in Leipzig. In 1834 he was appointed Professor of in Leipzig. But in 1839 he contracted an eye disorder while studying the phenomena of color and vision, and, after suffering many, resigned. Subsequently, while recovering, he turned to the study of the and its relationship with the body, giving public lectures on the topics discussed in his books. While lying in bed, Fechner had an idea of the relationship between mental sensations and material sensations. This understanding has proved to be significant in the development of psychology, as there is now a quantitative link between the mental and physical worlds. Fechner's contributions were published in chemical and physical works, as well as the chemical works of Joan-Batista Biota and Louis Juak Tinaard from French. He also wrote several poems and humorous works, such as Vergleichende Anatomie der Engel (1825), written under the pseudonym Dr. Misans. The epochal work of Elemente der Psychophysics Fechner was his Elemente der Psychophysik (1860). He began with a monistic thought that bodily facts and conscious facts, though not a accomplished one are different sides of the same reality. Its originality lies in trying to discover an exact mathematical connection between the two. The most famous result of his requests is a law known as the Weber-Fechner Act, which can be expressed as follows: In order for the intensity of sensation to increase in arithmetic progression, the stimulus must increase exponentially. The law has been deemed extremely useful, but to fail for very weak and very strong feelings. Within its useful range, Fechner's law is that sensation is a logarmic function of physical intensity. S.S. Stevens noted that such a law does not take into account the fact that perceived relationships between stimuli (e.g., black, dark gray, gray, light gray and white) remain unchanged with changes in overall intensity (i.e., in the level of document coverage). In his famous 1961 article entitled Honoring Fechner and Repealing His Law, he suggested that the intensity of stimulation should be linked to through the Law of Power. Fechner's overall formula for getting on the number of units in any sensation is the S q c journal R, where the S stands for the sensation, the R for the stimulus is numerically evaluated, and with for constant, which must be separately defined by the experiment in each particular order of sensitivity. Fechner's reasoning was criticized on the grounds that while incentives are composite, the feelings are not. Every sensation, says , presents itself as an indivisible unit; and it is utterly impossible to read any clear meaning in that they are mass units combined. Fechner's color pattern of Benham's disk In 1838, he also studied the still mysterious illusion of perceiving what is still known as the Fechner color effect, in which the colors are visible in a moving pattern of black and white. In 1894, the English journalist and amateur scholar Charles Benham allowed English speakers to learn about this effect by inventing a rotating peak bearing his name. It is not known whether Fechner and Benham met face-to-face for any reason. Median In 1878 Fechner published a paper in which he developed the notion of the median. Later he delved into experimental and thought to define the shapes and sizes of aesthetically pleasing objects. He mainly used the size of the paintings as a database. In his 1876 Vorschule der Aesthetik he used the method of extreme ranges for subjective judgments. Fechner is generally credited with introducing the median into official data analysis. Synesthesia In 1871, Fechner reported the first empirical study of colored lettering among 73 synesthetes. His work in the 1880s was followed by the work of . The Callosum Corps split one of Fechner's speculations about , touching the brain. time, it was known that the brain is bilateral symmetrical and that there is a deep separation between the two halves that are connected by a connective band of fibers called the body of calluses. Fechner suggested that if the calluses of the hull were separated, the result would be two separate streams of consciousness - the mind would become two. However, Fechner believed that his theory would never be tested; he was wrong. In the mid-twentieth century, Roger Sperry and worked on epileptic patients with a sectarian-hull callous and noticed that Fechner's idea was correct. The Gold Section fechner built ten rectangles with different width-to-length ratios and asked numerous observers to choose the best and worst shape of the rectangle. He was concerned about the visual appeal of rectangles with different proportions. Participants were explicitly instructed to ignore any associations they had with rectangles, such as objects of a similar ratio. The rectangles selected as the best by the highest number of participants and as the worst in terms of the number of participants had a ratio of 0.62 (21:34). This ratio is known as the golden section (or gold ratio) and refers to the ratio of rectangle width to length, which is the most attractive to the eyes. was involved in this study. However, there was some constant controversy about the experiment itself, since the fact that Fechner deliberately abandoned the results of the study did not fit his needs became known, with many mathematicians including Mario Livio refuting the outcome of the experiment. Two parts of normal distribution In his posthumously published Kollektivmasslehre (1897), Fechner presented sweistig Gauss'sche Gesetz or two parts of normal distribution, to accommodate the asymmetry he observed in empirical frequency distributions in many areas. The distribution was independently rediscovered by several authors working in various fields. Fechner's paradox in 1861, Fechner reported, that if he looked at the light with a darkened piece of glass above one eye, he closed that eye, the light seemed to become brighter, though less light came into his eyes. This phenomenon became known as the Fechner paradox. He has been the subject of numerous scientific papers, including in the 2000s. Fechner's influence, along with and , is recognized as one of the founders of modern . His clearest contribution was to demonstrate that because the mind was receptive to measurement and mathematical treatment, psychology had the potential to become a quantitative science. Theorists such as Immanuil Kant have long stated it was impossible, and so the science of psychology was also impossible. Although he had a huge influence on psychophysics, there were few real disciples of his general philosophy. was inspired by his work on psychophysics. William James also admired his work: in 1904 he wrote an admiring introduction to the English translation of Fahlein's Buchlein vom Leben nach dem Tode (Little Book of Life after Death). He also influenced , who refers to Fechner, presenting the concept of psychic terrain in his Interpretation of Dreams, which he illustrates with a microscope metaphor. Fechner's world concept was highly animistic. He felt the thrill of life all over the world, in plants, in earth, stars, full of the universe. Man stands halfway between the souls of plants and the souls of the stars, who are angels. God, the soul of the universe, must be conceived as an existence similar to that of humans. Natural laws are just ways of revealing God's perfection. In his latest work, Fechner, in an age but full of hope, contrasts this joyful day view of the world with a dead, dreary night view of . Fechner's work in aesthetics is also important. He conducted experiments to show that certain abstract shapes and proportions naturally please our senses, and gave some new illustrations of the work of the aesthetic association. Charles Hartshorn saw him as a predecessor in 's philosophy and regretted that Fechner's philosophical work had been ignored for so long. Fechner's position towards his predecessors and contemporaries is not very clearly defined. He was a distant disciple of Schelling, learned a lot from , G.V. Leibniz, , and , and strongly rejected G.V. F. Hegel and Rudolf Herman Lotze's monadism. Fechner's work continues to influence modern science, inspiring researchers such as Ian Kenderink, Farley Norman, David Higer and others to further explore human perception abilities. Fechner's honorary crater In 1970, the International Astronomical Union named a crater on the far side of the moon after Fechner. Fechner Day In 1985, the International Society of Psychophysics called its annual conference Fechner Day. The conference is now scheduled to include October 22nd to psychophysics to celebrate the anniversary of Fechner's awakening on this day in 1850 with a new approach in how to study the mind. Fechner Day is held annually and Fechner Day in 2018 is the 34th. Little's family and later life are known for Fechner's later years, as well as the circumstances, cause and manner of his death. Fechner was the brother of artist Eduard Clemens and Clementine Vic Fechner, who was Clara Wick's stepmother when Clementine became the second wife of her father Friedrich Wick.
