Handwritten
Handwriting is the writing done with a writing instrument, such as a pen or pencil, in the hand. Handwriting includes both printing and cursive styles and is separate from formal calligraphy or typeface. Because each person's handwriting is unique and different, it can be used to verify a document's writer. The deterioration of a person's handwriting is also a symptom or result of several different diseases. The inability to produce clear and coherent handwriting is also known as dysgraphia. Uniqueness Each person has their own unique style of handwriting, whether it is everyday handwriting or their personal signature. Cultural environment and the characteristics of the written form of the first language that one learns to write are the primary influences on the development of one's own unique handwriting style.Sargur Srihari, Chen Huang and Harish Srinivasan (March 2008)"On the Discriminability of the Handwriting of Twins" ''J Forensic Sci.''; 53(2):430–46.

Questioned Document Examination
In forensic science, questioned document examination (QDE) is the examination of documents potentially disputed in a court of law. Its primary purpose is to provide evidence about a suspicious or questionable document using scientific processes and methods. Evidence might include alterations, the chain of possession, damage to the document, forgery, origin, authenticity, or other questions that come up when a document is challenged in court. Overviews Many QDE involve a comparison of the questioned document, or components of the document, to a set of known standards. The most common type of examination involves handwriting wherein the examiner tries to address concerns about potential authorship. A document examiner is often asked to determine if a questioned item originated from the same source as the known item(s), then present their opinion on the matter in court as an expert witness. Other common tasks include determining what has happened to a document, determining when a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isaiah Scroll
The Isaiah Scroll, designated 1QIsaa and also known as the Great Isaiah Scroll, is one of the seven Dead Sea Scrolls that were first discovered by Bedouin shepherds in 1946 from Qumran List of manuscripts from Qumran Cave 1, Cave 1. The scroll is written in Hebrew and contains the entire Book of Isaiah from beginning to end, apart from a few small damaged portions.The Digital Dead Sea Scrolls: The Great Isaiah Scroll ''dss.collections.imj.org'' It is the oldest complete copy of the Book of Isaiah, being approximately 1000 years older than the oldest Hebrew language, Hebrew manuscripts known before the scrolls' discovery. 1QIsaa is also notable in being the only scroll from the Qumran Caves to be preserved almost in its entirety. The scroll is written on 17 shee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typeface
A typeface (or font family) is the design of lettering that can include variations in size, weight (e.g. bold), slope (e.g. italic), width (e.g. condensed), and so on. Each of these variations of the typeface is a font. There are list of typefaces, thousands of different typefaces in existence, with new ones being developed constantly. The art and craft of designing typefaces is called ''type design''. Designers of typefaces are called ''type designers'' and are often employed by ''type foundry, type foundries''. In desktop publishing, type designers are sometimes also called ''font developers'' or ''font designers''. Every typeface is a collection of glyphs, each of which represents an individual letter, number, punctuation mark, or other symbol. The same glyph may be used for character (symbol), characters from different scripts, e.g. Roman uppercase A looks the same as Cyrillic uppercase А and Greek uppercase alpha. There are typefaces tailored for special applications, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Correlation
In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Although in the broadest sense, "correlation" may indicate any type of association, in statistics it usually refers to the degree to which a pair of variables are ''linearly'' related. Familiar examples of dependent phenomena include the correlation between the height of parents and their offspring, and the correlation between the price of a good and the quantity the consumers are willing to purchase, as it is depicted in the so-called demand curve. Correlations are useful because they can indicate a predictive relationship that can be exploited in practice. For example, an electrical utility may produce less power on a mild day based on the correlation between electricity demand and weather. In this example, there is a causal relationship, because extreme weather causes people to use more electricity for heating or cooling. However ...

Pseudoscience
Pseudoscience consists of statements, beliefs, or practices that claim to be both scientific and factual but are incompatible with the scientific method. Pseudoscience is often characterized by contradictory, exaggerated or falsifiability, unfalsifiable claims; reliance on confirmation bias rather than rigorous attempts at refutation; lack of openness to Peer review, evaluation by other experts; absence of systematic practices when developing Hypothesis, hypotheses; and continued adherence long after the pseudoscientific hypotheses have been experimentally discredited. The demarcation problem, demarcation between science and pseudoscience has scientific, philosophical, and political implications. Philosophers debate the nature of science and the general criteria for drawing the line between scientific theory, scientific theories and pseudoscientific beliefs, but there is general agreement on examples such as ancient astronauts, climate change denial, dowsing, evolution denial, ...

Graphology
Graphology is the analysis of handwriting with attempt to determine someone's personality traits. No scientific evidence exists to support graphology, and it is generally considered a pseudoscience or scientifically questionable practice. However, it remains in widespread use in France and has historically been considered legitimate for use in some court cases. The term is sometimes incorrectly used to refer to forensic document examination, due to the fact that aspects of the latter dealing with the examination of handwritten documents are occasionally referred to as '' graphanalysis''. Historian Laurens Schlicht states that while graphology failed to become a scientific discipline, many experts in experimental psychology and psychiatry participated in the endeavour to study graphology within a broader, more recognized science of expression, and that "to qualify something as pseudoscience can thus easily result in an unsystematic examination of a historical constellation of k ...

ADHD
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by excessive amounts of inattention, hyperactivity, and impulsivity that are pervasive, impairing in multiple contexts, and otherwise age-inappropriate. ADHD symptoms arise from executive dysfunction, and emotional dysregulation is often considered a core symptom. In children, problems paying attention may result in poor school performance. ADHD is associated with other neurodevelopmental and mental disorders as well as some non-psychiatric disorders, which can cause additional impairment, especially in modern society. Although people with ADHD struggle to focus on tasks they are not particularly interested in completing, they are often able to maintain an unusually prolonged and intense level of attention for tasks they do find interesting or rewarding; this is known as hyperfocus. The precise causes of ADHD are unknown in the majority of cases. Genetic factors play an import ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dyslexia
Dyslexia, also known until the 1960s as word blindness, is a disorder characterized by reading below the expected level for one's age. Different people are affected to different degrees. Problems may include difficulties in spelling words, reading quickly, writing words, "sounding out" words in the head, pronouncing words when reading aloud and understanding what one reads. Often these difficulties are first noticed at school. The difficulties are involuntary, and people with this disorder have a normal desire to learn. People with dyslexia have higher rates of attention deficit hyperactivity disorder (ADHD), developmental language disorders, and difficulties with numbers. Dyslexia is believed to be caused by the interaction of genetic and environmental factors. Some cases run in families. Dyslexia that develops due to a traumatic brain injury, stroke, or dementia is sometimes called "acquired dyslexia" or alexia. The underlying mechanisms of dyslexia result from differ ...

Dysgraphia
Dysgraphia is a learning disability of written expression, which affects the ability to write, primarily handwriting, but also coherence. It is a specific learning disability (SLD) as well as a transcription disability, meaning that it is a writing disorder associated with impaired handwriting, orthographic coding and finger sequencing (the movement of muscles required to write). It often overlaps with other learning disabilities and neurodevelopmental disorders such as speech impairment, attention deficit hyperactivity disorder (ADHD) or developmental coordination disorder (DCD). In the '' Diagnostic and Statistical Manual of Mental Disorders'' (''DSM-IV''), dysgraphia is characterized as a learning disability in the category of written expression, when one's writing skills are below those expected given a person's age measured through intelligence and age-appropriate education. The DSM is unclear in whether writing refers only to the motor skills involved in writing, or if i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calligraphy
Calligraphy (from el, link=y, καλλιγραφία) is a visual art related to writing. It is the design and execution of lettering with a pen, ink brush, or other writing instrument. Contemporary calligraphic practice can be defined as "the art of giving form to signs in an expressive, harmonious, and skillful manner". Modern calligraphy ranges from functional inscriptions and designs to fine-art pieces where the letters may or may not be readable. Classical calligraphy differs from type design and non-classical hand-lettering, though a calligrapher may practice both. CD-ROM Calligraphy continues to flourish in the forms of wedding invitations and event invitations, font design and typography, original hand-lettered logo design, religious art, announcements, graphic design and commissioned calligraphic art, cut stone inscriptions, and memorial documents. It is also used for props and moving images for film and television, and also for testimonials, birth and death cert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voynich Manuscript
The Voynich manuscript is an illustrated codex hand-written in an otherwise unknown writing system, referred to as 'Voynichese'. The vellum on which it is written has been carbon-dated to the early 15th century (1404–1438), and stylistic analysis indicates it may have been composed in Italy during the Italian Renaissance. The origins, authorship, and purpose of the manuscript are debated. Various hypotheses have been suggested, including that it is an otherwise unrecorded script for a natural language or constructed language; an unread code, cypher, or other form of cryptography; or simply a meaningless hoax. The manuscript currently consists of around 240 pages, but there is evidence that additional pages are missing. Some pages are foldable sheets of varying size. Most of the pages have fantastical illustrations or diagrams, some crudely coloured, with sections of the manuscript showing people, fictitious plants, astrological symbols, etc. The text is written from left to r ...

Cursive
Cursive (also known as script, among other names) is any style of penmanship in which characters are written joined in a flowing manner, generally for the purpose of making writing faster, in contrast to block letters. It varies in functionality and modern-day usage across languages and regions; being used both publicly in artistic and formal documents as well as in private communication. Formal cursive is generally joined, but casual cursive is a combination of joins and pen lifts. The writing style can be further divided as "looped", "italic script, italic" or "connected". The cursive method is used with many alphabets due to infrequent pen lifting and beliefs that it increases writing speed. Despite this belief, more elaborate or ornamental styles of writing can be slower to reproduce. In some alphabets, many or all letters in a word are connected, sometimes making a word one single complex stroke. A study of gradeschool children in 2013 discovered that the speed of their cu ...
