Cardano made several contributions to hydrodynamics and held that perpetual motion is impossible, except in celestial bodies. He published two encyclopedias of natural science which contain a wide variety of inventions, facts, and occult superstitions. He also introduced the Cardan grille ,
255-501: A lead -based alloy which suited printing purposes so well that it is still used today. The mass production of metal letters was achieved by his key invention of a special hand mould , the matrix . The Latin alphabet proved to be an enormous advantage in the process because, in contrast to logographic writing systems , it allowed the type-setter to represent any text with a theoretical minimum of only around two dozen different letters. Another factor conducive to printing arose from

Once the correct number of pages were composed, the galleys would be laid face up in a frame, also known as a forme, which itself is placed onto a flat stone, 'bed,' or 'coffin.' The text is inked using two balls , pads mounted on handles. The balls were made of dog skin leather, because it has no pores, and stuffed with sheep's wool and were inked. This ink

It is also of interest to scholars of historically informed performance practice for its details on 16th century performance. The later treatise of music Della natura de principii et regole musicali which has been attributed to Cardano by some, is according to The New Grove Dictionary of Music and Musicians most likely falsely attributed to Cardano and

Significantly, in the history of education of the deaf , he said that deaf people were capable of using their minds, argued for the importance of teaching them, and was one of the first to state that deaf people could learn to read and write without learning how to speak first. He was familiar with a report by Rudolph Agricola about a deaf-mute who had learned to write. Cardano's medical writings included:

In his exposition, he acknowledged the existence of what are now called imaginary numbers , although he did not understand their properties, described for the first time by his Italian contemporary Rafael Bombelli . In Opus novum de proportionibus he introduced the binomial coefficients and the binomial theorem . Cardano
765-650: A few decades. From a single print shop in Mainz , Germany, printing had spread to no less than around 270 cities in Central, Western and Eastern Europe by the end of the 15th century. As early as 1480, there were printers active in 110 different places in Germany, Italy, France , Spain , the Netherlands , Belgium , Switzerland , England , Bohemia and Poland . From that time on, it is assumed that "the printed book

He produced his machine with assistance from German engineer Andreas Friedrich Bauer . In 1814, Koenig and Bauer sold two of their first models to The Times in London , capable of 1,100 impressions per hour. The first edition so printed was on 28 November 1814. They improved the early model so that it could print on both sides of

The advent of the printing press brought with it issues involving censorship and freedom of the press. The invention of mechanical movable type printing led to a huge increase of printing activities across Europe within only
1105-448: A paper mill. However, it was not until a 1439 lawsuit against Gutenberg that an official record existed; witnesses' testimony discussed Gutenberg's types, an inventory of metals (including lead), and his type molds. Having previously worked as a professional goldsmith, Gutenberg made skillful use of the knowledge of metals he had learned as a craftsman. He was the first to make type from an alloy of lead , tin , and antimony , which

The tympans, inner and outer, are thin iron frames, one fitting into the other, on each of which is stretched a skin of parchment or a breadth of fine cloth. A woollen blanket or two with a few sheets of paper are placed between these, the whole thus forming a thin elastic pad, on which

General: Printing presses: Other inventions: From old price tables it can be deduced that the capacity of a printing press around 1600, assuming a fifteen-hour workday, was between 3.200 and 3.600 impressions per day. This method almost doubled
1360-432: A sheet at once. This began the long process of making newspapers available to a mass audience, which helped spread literacy. From the 1820s it changed the nature of book production, forcing a greater standardization in titles and other metadata . Their company Koenig & Bauer AG is still one of the world's largest manufacturers of printing presses today. The steam-powered rotary printing press , invented in 1843 in
1445-557: A single Renaissance movable-type printing press could produce up to 3,600 pages per workday, compared to forty by hand-printing and a few by hand-copying . Gutenberg's newly devised hand mould made possible the precise and rapid creation of metal movable type in large quantities. His two inventions, the hand mould and the movable-type printing press, together drastically reduced the cost of printing books and other documents in Europe, particularly for shorter print runs. From Mainz ,

As printing material he used both paper and vellum (high-quality parchment). In the Gutenberg Bible , Gutenberg made a trial of colour printing for a few of the page headings, present only in some copies. A later work, the Mainz Psalter of 1453, presumably designed by Gutenberg but published under

A small rotating handle called the 'rounce' is used to do this, and the impression is made with a screw that transmits pressure through the platen. To turn the screw the long handle attached to it is turned. This is known as the bar or 'Devil's Tail.' In a well-set-up press, the springiness of the paper, frisket, and tympan caused the bar to spring back and raise

Printing press#The Industrial Revolution A printing press is a mechanical device for applying pressure to an inked surface resting upon a print medium (such as paper or cloth ), thereby transferring the ink. It marked a dramatic improvement on earlier printing methods in which the cloth, paper, or other medium was brushed or rubbed repeatedly to achieve
2125-500: The 42-line Bible . After much experimentation, Gutenberg managed to overcome the difficulties which traditional water-based inks caused by soaking the paper, and found the formula for an oil-based ink suitable for high-quality printing with metal type. A printing press, in its classical form, is a standing mechanism, ranging from 5 to 7 feet (1.5 to 2.1 m) long, 3 feet (0.91 m) wide, and 7 feet (2.1 m) tall. The small individual metal letters known as type would be set up by
2210-603: The Mediterranean and medieval diet . The device was also used from very early on in urban contexts as a cloth press for printing patterns. Gutenberg may have also been inspired by the paper presses which had spread through the German lands since the late 14th century and which worked on the same mechanical principles. During the Islamic Golden Age , Arab Muslims were printing texts, including passages from

After a depressing childhood, with frequent illnesses, and the rough upbringing by his overbearing father, in 1520, Cardano entered the University of Pavia . Against the wish of his father, who wanted his son to undertake studies of law, Girolamo felt more attracted to philosophy and science. During the Italian War of 1521–1526 , however,

In Egypt during the Fatimid era, the printing technique was adopted reproducing texts on paper strips by hand and supplying them in various copies to meet the demand. Gutenberg adopted the basic design, thereby mechanizing

Mass production of printed works flourished after the transition to rolled paper, as continuous feed allowed the presses to run at a much faster pace. Hoe's original design operated at up to 2,000 revolutions per hour where each revolution deposited 4 page images, giving the press a throughput of 8,000 pages per hour. By 1891, The New York World and Philadelphia Item were operating presses producing either 90,000 4-page sheets per hour or 48,000 8-page sheets. In

In his autobiography, Cardano wrote that his mother, Chiara Micheri, had taken "various abortive medicines" to terminate the pregnancy; he said: "I was taken by violent means from my mother; I was almost dead." She was in labour for three days. Shortly before his birth, his mother had to move from Milan to Pavia to escape

Cardano was arrested by the Inquisition in 1570 after an accusation of heresy by the Inquisitor of Como, who targeted Cardano's De rerum varietate (1557). The inquisitors complained about Cardano's writings on astrology , especially his claim that self-harming religiously motivated actions of martyrs and heretics were caused by
3145-658: The author was less important, since a copy of Aristotle made in Paris would not be exactly identical to one made in Bologna. For many works prior to the printing press, the name of the author has been entirely lost. Because the printing process ensured that the same information fell on the same pages, page numbering, tables of contents , and indices became common, though they previously had not been unknown. The process of reading also changed, gradually moving over several centuries from oral readings to silent, private reading. Over

His eccentric and confrontational style did not earn him many friends and he had a difficult time finding work after he completed his studies. In 1525, Cardano repeatedly applied to the College of Physicians in Milan, but

He demonstrated the efficacy of defining odds as the ratio of favourable to unfavourable outcomes (which implies that the probability of an event is given by the ratio of favourable outcomes to the total number of possible outcomes). He was also aware of the multiplication rule for independent events but was not certain about what values should be multiplied. Cardano

3570-415: The detriment of Latin 's status as lingua franca . In the 19th century, the replacement of the hand-operated Gutenberg-style press by steam-powered rotary presses allowed printing on an industrial scale. The rapid economic and socio-cultural development of late medieval society in Europe created favorable intellectual and technological conditions for Gutenberg's improved version of the printing press:
3655-420: The entrepreneurial spirit of emerging capitalism increasingly made its impact on medieval modes of production, fostering economic thinking and improving the efficiency of traditional work processes. The sharp rise of medieval learning and literacy amongst the middle class led to an increased demand for books which the time-consuming hand-copying method fell far short of accommodating. Technologies preceding
3740-537: The establishment of widely disseminated scholarly journals, helping to bring on the Scientific Revolution . Because of the printing press, authorship became more meaningful and profitable. It was suddenly important who had said or written what, and what the precise formulation and time of composition was. This allowed the exact citing of references, producing the rule, "One Author, one work (title), one piece of information" (Giesecke, 1989; 325). Before,
3825-447: The first copyright laws were passed. On the other hand, the printing press was criticized for allowing the dissemination of information that may have been incorrect. A second outgrowth of this popularization of knowledge was the decline of Latin as the language of most published works, to be replaced by the vernacular language of each area, increasing the variety of published works. The printed word also helped to unify and standardize
3910-669: The first copper movable type. This received limited use compared to woodblock printing. The technology spread outside China, as the oldest printed book using metal movable type was the Jikji , printed in Korea in 1377 during the Goryeo era. Other notable examples include the Prüfening inscription from Germany, letter tiles from England and Altarpiece of Pellegrino II in Italy. However,

Nonetheless, the limitations inherent to the traditional method of printing became obvious. Two ideas altered the design of the printing press radically: First, the use of steam power for running the machinery, and second the replacement of
4080-632: The former sojourn of the sea upon the mountains. In 1552 Cardano travelled to Scotland with the Spanish physician William Casanatus, via London, to treat the Archbishop of St Andrews who suffered of a disease that had left him speechless and was thought incurable. The treatment was a success and the diplomat Thomas Randolph recorded that "merry tales" about Cardano's methods were still current in Edinburgh in 1562. Cardano and Casanatus argued over
4165-503: The ground that the author of the astrological works deserves to be listened to even when he is wrong. English novelist E. M. Forster 's Abinger Harvest , a 1936 volume of essays, authorial reviews and a play, provides a sympathetic treatment of Cardano in the section titled 'The Past'. Forster believes Cardano was so absorbed in "self-analysis that he often forgot to repent of his bad temper, his stupidity, his licentiousness, and love of revenge" (212). A chronological key to this edition
4250-422: The happiest days of his life. With the help of a few noblemen, Cardano obtained a mathematics teaching position in Milan. Having finally received his medical license, he practised mathematics and medicine simultaneously, treating a few influential patients in the process. Because of this, he became one of the most sought-after doctors in Milan. In fact, by 1536, he was able to quit his teaching position, although he

The Printing Revolution occurred when the spread of the printing press facilitated the wide circulation of information and ideas, acting as an "agent of change" through the societies that it reached. Demand for bibles and other religious literature was one of the main drivers of the very rapid initial expansion of printing. Much later, printed literature played

The operation of a press became synonymous with the enterprise of printing and lent its name to a new medium of expression and communication, " the press ". The spread of mechanical movable type printing in Europe in the Renaissance introduced the era of mass communication , which permanently altered the structure of society. The relatively unrestricted circulation of information and (revolutionary) ideas transcended borders, captured
4505-469: The masses in the Reformation , and threatened the power of political and religious authorities. The sharp increase in literacy broke the monopoly of the literate elite on education and learning and bolstered the emerging middle class . Across Europe, the increasing cultural self-awareness of its peoples led to the rise of proto- nationalism and accelerated the development of European vernaculars , to

Jobbing presses were capable of quick setup, with an average setup time for a small job was under 15 minutes, and quick production. Even on treadle-powered jobbing presses it was considered normal to get 1,000 impressions per hour [iph] with one pressman, with speeds of 1,500 iph often attained on simple envelope work. Job printing emerged as

4760-458: The movable-type printing press spread within several decades to over 200 cities in a dozen European countries. By 1500, printing presses in operation throughout Western Europe had already produced more than 20 million volumes. In the 16th century, with presses spreading further afield, their output rose tenfold to an estimated 150 to 200 million copies. By the mid-17th century, the first printing presses arrived in colonial America in response to
4845-538: The next 200 years, the wider availability of printed materials led to a dramatic rise in the adult literacy rate throughout Europe. The printing press was an important step towards the democratization of knowledge . Within 50 or 60 years of the invention of the printing press, the entire classical canon had been reprinted and widely promulgated throughout Europe (Eisenstein, 1969; 52). More people had access to knowledge both new and old, more people could discuss these works. Book production became more commercialised, and
4930-589: The page, did not exceed an output of forty pages per day. Of Erasmus 's work, at least 750,000 copies were sold during his lifetime alone (1469–1536). In the early days of the Reformation, the revolutionary potential of bulk printing took princes and papacy alike by surprise. In the period from 1518 to 1524, the publication of books in Germany alone skyrocketed sevenfold; between 1518 and 1520, Luther 's tracts were distributed in 300,000 printed copies. The rapidity of typographical text production, as well as

The function of the printing press was described by William Skeen in 1872: this sketch represents
5100-431: The press that led to the press's invention included: manufacturing of paper , development of ink, woodblock printing , and invention of eyeglasses . At the same time, a number of medieval products and technological processes had reached a level of maturity which allowed their potential use for printing purposes. Gutenberg took up these far-flung strands, combined them into one complete and functioning system, and perfected

Despite this it appears that the final breakthrough of paper depended just as much on the rapid spread of movable-type printing.

Introduced in the 1st century AD by the Romans , it was commonly employed in agricultural production for pressing grapes for wine and olives for oil, both of which formed an integral part of
5525-501: The printing process. Printing, however, put a demand on the machine quite different from pressing. Gutenberg adapted the construction so that the pressing power exerted by the platen on the paper was now applied both evenly and with the required sudden elasticity. To speed up the printing process, he introduced a movable undertable with a plane surface on which the sheets could be swiftly changed. The concept of movable type existed prior to 15th century Europe; sporadic evidence that

At the same time, then, as the printing press in the physical, technological sense was invented, 'the press' in the extended sense of the word also entered the historical stage. The phenomenon of publishing was born. The outstanding difference between the two ends of the Old World was the absence of screw-presses from China, but this

At the dawn of the Industrial Revolution , the mechanics of the hand-operated Gutenberg-style press were still essentially unchanged, although new materials in its construction, amongst other innovations, had gradually improved its printing efficiency. By 1800, Lord Stanhope had built a press completely from cast iron which reduced

5865-491: The scroll. A fourth development was the early success of medieval papermakers at mechanizing paper manufacture. The introduction of water-powered paper mills , the first certain evidence of which dates to 1282, allowed for a massive expansion of production and replaced the laborious handcraft characteristic of both Chinese and Muslim papermaking. Papermaking centres began to multiply in the late 13th century in Italy , reducing

The frisket is a slender frame-work, covered with coarse paper, on which an impression is first taken; the whole of the printed part is then cut out, leaving apertures exactly corresponding with the pages of type on the carriage of the press. The frisket when folded on to the tympans, and both turned down over the forme of types and run in under the platten, preserves
6205-492: The spelling and syntax of these vernaculars, in effect 'decreasing' their variability. This rise in importance of national languages as opposed to pan-European Latin is cited as one of the causes of the rise of nationalism in Europe. A third consequence of popularization of printing was on the economy. The printing press was associated with higher levels of city growth. The publication of trade-related manuals and books teaching techniques like double-entry bookkeeping increased

Cardano was imprisoned for several months and lost his professorship in Bologna. He abjured and was freed, probably with help from powerful churchmen in Rome. All his non-medical works were prohibited and placed on the Index . He moved to Rome, where he received

Typically used for texts, the invention and global spread of the printing press was one of the most influential events in the second millennium. In Germany , around 1440, the goldsmith Johannes Gutenberg invented the movable-type printing press, which started the Printing Revolution . Modelled on the design of existing screw presses ,
6460-513: The various techniques employed (imprinting, punching and assembling individual letters) did not have the refinement and efficiency needed to become widely accepted. Tsuen-Hsuin and Needham, and Briggs and Burke suggest that the movable-type printing in China and Korea was rarely employed. Gutenberg greatly improved the process by treating typesetting and printing as two separate work steps. A goldsmith by profession, he created his type pieces from
6545-414: Was a music theorist who studied music privately in Milan in his youth. He wrote two treatises on music, both of which were titled De Musica . The first was published within his 1663 work Hieronymi Cardani Mediolanensis Opera Omnia . It is of interest to scholars on the history of woodwind instruments because of its discussion of instruments from that family. The second treatise was published in 1574, and
6630-558: Was critical for producing durable type that produced high-quality printed books and proved to be much better suited for printing than all other known materials. To create these lead types, Gutenberg used what is considered one of his most ingenious inventions, a special matrix enabling the quick and precise molding of new type blocks from a uniform template. His type case is estimated to have contained around 290 separate letter boxes, most of which were required for special characters, ligatures , punctuation marks , and so forth. Gutenberg
6715-548: Was in universal use in Europe". In Italy, a center of early printing, print shops had been established in 77 cities and towns by 1500. At the end of the following century, 151 locations in Italy had seen at one time printing activities, with a total of nearly three thousand printers known to be active. Despite this proliferation, printing centres soon emerged; thus, one third of the Italian printers published in Venice . By 1500,
6800-584: Was not admitted owing to his combative reputation and illegitimate birth. However, he was consulted by many members of the College of Physicians, because of his irrefutable intelligence. Cardano wanted to practice medicine in a large, rich city like Milan , but he was denied a license to practice, so he settled for the town of Piove di Sacco , where he practised without a license. There, he married Lucia Banderini in 1531. Before her death in 1546, they had three children, Giovanni Battista (1534), Chiara (1537) and Aldo Urbano (1543). Cardano later wrote that those were
6885-421: Was not described by Cardano. As quoted from Charles Lyell 's Principles of Geology : The title of a work of Cardano's, published in 1552, De Subtilitate (corresponding to what would now be called transcendental philosophy ), would lead us to expect, in the chapter on minerals, many far fetched theories characteristic of that age; but when treating of petrified shells, he decided that they clearly indicated
6970-402: Was notoriously short of money and kept himself solvent by being an accomplished gambler and chess player. His book about games of chance, Liber de ludo aleae ("Book on Games of Chance"), written around 1564, but not published until 1663, contains the first systematic treatment of probability , as well as a section on effective cheating methods. He used the game of throwing dice to understand
7055-404: Was put to trial and, when Cardano could not pay the restitution demanded by the victim's family, was sentenced to death and beheaded . Gerolamo's other son Aldo Urbano was a gambler, who stole money from his father, and so Cardano disinherited him in 1569. Cardano moved from Pavia to Bologna, in part because he believed that the decision to execute his son was influenced by Gerolamo's battles with
7140-470: Was still interested in mathematics. His notability in the medical field was such that the aristocracy tried to lure him out of Milan. Cardano later wrote that he turned down offers from the kings of Denmark and France, and the Queen of Scotland. Gerolamo Cardano was the first European mathematician to make systematic use of negative numbers. He published with attribution the solution of Scipione del Ferro to
7225-420: Was then applied to the text evenly. One damp piece of paper was then taken from a heap of paper and placed on the tympan. The paper was damp as this lets the type 'bite' into the paper better. Small pins hold the paper in place. The paper is now held between a frisket and tympan (two frames covered with paper or parchment). These are folded down, so that the paper lies on the surface of the inked type. The bed
