My skin has another skin

MY VALIANT SOUL

Image result for sad paintings image credits- SuzanNeellis

I am anxious like the painting of Mona Lisa

Curated with my own jitters,

There is a platter of loss, rumbling loud inside

where the web of splinters corrode my skin

And you may see my second skin,

for pain is the language of skin.

The mouth of a cave is that invincible spot of the moon

so, the mouth resides inside my blood.

Where the droolings of grey skies touch my bare shoulder

screeching. ( the inside is the rupture of seeds, with no desire of flowers)

Total Darkness. Cold distilled blue.

Yet, the poetry of inside soul speaks an

array of hopeful rainbows.

Days of Sadness

Grave

When Sandy died
I felt so down,
my soul had been ripped
from out of my body.

Why did she die
doctors say she collapsed,
her body burned out
we would never talk again.

Clothes in her wardrobe
clothes in her cabinet,
hair brush and perfume
all neatly lined up.

I get up each day
waiting for life’s end,
knowing she is waiting
to be together, once again.

 

Leonardo da Vinci: The Last Supper

Last Supper

The Last Supper by Leonardo da Vinci

When one refers to the name Leonardo da Vinci, “The Last Supper” is considered as one of his finest works.

The painting was commissioned by Sforza to be the centre piece of the mausoleum at the Convent of Santa Maria delle Grazie, Milan, Italy and measures some 15 feet x 29 feet in size.

The disciples sit either side of Jesus as depicted in the picture, all displaying facial emotions, which relate to him telling them he would be betrayed by one of them.

Looking at the picture we see Bartholomew, James son of Alphaeus and Andrew form a group of three, with a surprised look upon their faces, and seated on the far left.  Next we have Judas Iscariot, Peter and John form the next group of three; Judas partly covers his face, Peter shows anger and John looks ready to confront the perpetrator.

Jesus sits in the middle backed by three windows.

Thomas, James the Greater and Phillip sit as another group of three to his right.  Thomas is upset by such a suggestion, James appears stunned and Phillip seeks an answer.  Mathew, Jude Thaddeus and Simon the Zealot make up the final group of three; Jude and Mathew gaze at Simon believing he has the answer.

Over the centuries the image has fallen apart.  The reason for this is that if Leonardo had kept to the time old tradition of using tempera on wet plaster, the proffered method for fresco paintings, rather than experimenting using dry plaster for a more varied palette.  The image might have stood up to the years of neglect.

Instead his experimental method, proved to be a failure, and neglect saw the painting undergo many restorations over the centuries.

The painting was completed on 9th February 1498, and early signs of flaking were visible by 1517.

  • In 1652 a doorway was cut through the picture but later bricked up.
  • In 1726 Michelangelo Bellotti carried out a restoration by filling in missing parts using oil paint, and then varnished the whole picture.
  • In 1768, a curtain was hung over it as a form of protection, but when pulled back it scratched at the flaking paint.
  • In 1770 Giuseppe Mazza stripped off Bellotti’s repair, and repainted nine of the faces, but was halted due to public outrage.

In 1796 the French revolutionary troops used the refectory as an armoury, and threw stones at the image and later it became a prison.

  • In 1821 Stefano Barezzi attempted the removal of the painting, but was forced to re-attach damaged parts with glue.
  • In 1901-1908 Luigi Cavenaghi studied the structure of the painting, and cleaned it.
  • In 1921 Oreste Silvestri cleaned it further, and stabilised parts using stucco.

During World War II, the refectory wall was protected with sandbags, and managed to survive, when on 15th August 1943, the refectory was bombed.

  • 1951-1954 Mauro Pelliccioli cleaned and restored the image.
  • 1978-1999 Pinn Brambilla Barcilon undertook a restoration project to save this most important work from total destruction.

On the 28th May 1999 the painting was put back on show, for the entire world to see.

Birth of Computers

Abacus

Abacus Counting System

Who invented the computer, which is part of everyday use?  To get to this point we need to start back at the time, where it all began!

The earliest form of counting device would be the Tally Stick, but the one we all remember from our childhood days would be the Abacus first used in Babylonia in 2400BC.

The Astrolabe and the Antikythera Analog Mechanical Computers, were used in Ancient Greece in 150-100BC to perform astronomical calculations.  The Panisphere in AD1000 by Abu Rayhan al-Biruni. The Equatorium by Abu Ishaq Ibrahim al–Zarqali in AD1015 and the Astronomical Clock Tower of Su Song during the Song Dynasty AD1090.

Napier Bones

Napier Bones

In 1617, John Napier Scottish mathematician and physicist invented the Napier Bones, a device similar in appearance to that of an abacus, which could perform multiplication and division calculations.  In the 1620’s the Slide Rule was invented, a device to allow multiplication and division, using the basis of distances and line intervals to create the answer.  The use of the slide rule, faded out with the invention of the Pocket Calculator.

Wilhelm Schickard, A German designed the Calculating Clock in 1623, but it was destroyed by fire during construction in 1624, and the clock was never rebuilt.

In 1642 Blaise Pascal invented the mechanical calculator, and duly named it; Pascal’s Pascaline.

The Stepped Reckoner was invented by Gottfried Wilhelm von Leibniz in 1672, and came about, whilst using Pascal’s Pascaline machine.

The Frenchman, Joseph Marie Jacquard invented the Powered Loom in 1801.  It used Punched Wooden Cards, which defined the weaves pattern.  These wooden cards in relation to today’s world of computers would be the equivalent of a software program.

The Arithmometer invented by Charles Xavier Thomas de Colmar, was to become the first mass produced mechanical calculator in the 1820’s.  For it could add, subtract, multiply and divide.In 1837 Charles Babbage invented the first Mechanical Computer, using his Analytical Engine.  The device was never finished during his lifetime, and it was left to his son Henry, to complete the work in 1888 in a simplified form: The Mill.

Ada Lovelace daughter of the poet, Lord Byron, was analyst of the Babbage analytical engine, and went on to create the first computer program between 1842-1843.  For it was her vision that computers would be capable of performing more than basic arithmetic calculations.

Herman Hollerith invented a machine to read and record punched cards; the Tabulator, and Keypunch machines towards the end of the 1880’s, like the Hollerith Desk, used by the U.S. to carry out the 1890 census.  He went on to open a Tabulating Machine Company on the back of its success, which eventually became International Business Machines (IBM).

Alan Turing considered by many as the father of computer science.  For it was in 1936 he provided the concept of algorithm and computation with the Turing Machine, and the blueprint for the first electronic digital computer.

Just think, when you turn on your computer, your actually using a design based on the brain child of Alan Turing.

In 1947, one Howard Aiken had been commissioned by IBM to determine how many computers it would take to run the United States… His answer was six.  How wrong had he been, who would have believed most homes would have at least one computer, some sixty-six years later.

In 1936 the first computer was built by Kenrad Zuse the Z1, believed to be the first electro-mechanical binary programmable computer.

In November 1937 whilst working at Bell Labs George Stibitz invented the Model K relay based calculator, which used binary circuits to perform calculations.

John Atanasoff a Physics professor from Iowa, built the first electronic digital computer in 1937, assisted by graduate student Clifford Berry.  It hadn’t been constructed as a programmable machine, for its main purpose was to deal with linear equations.

Konrad Zuse who built the Z1 back in 1936, took his invention to the next stage in 1941, by building the first program controlled electromechanical computing machine; the Z3.

Colossus

Colossus Computer

Thomas Flowers joined the Post Office Research Branch in 1930, where he became Head of Switching Research. During the 1930s Flowers pioneered large-scale digital electronics.  Then in 1943 he designed and constructed the British Computer; Colossus.

Harry Fensom joined Flowers’ inner circle of engineers at the Research Branch of the British Post Office in 1942. He participated in the construction of the code breaking machine, Colossus, and was responsible for keeping it in continuous operation at Bletchley Park.

It was the world’s first electronic programmable computer, consisting of a large number of vacuum tubes.  Even though it had its limits, when it came to programming, its main use was in breaking German wartime codes.

In 1939 development started on the Harvard Mark I, an Automatic Sequence Controlled Calculator.  In fact it was a general purpose electro-mechanical computer by Howard Aiken and Grace Hopper, and financed by IBM.  It came into use in May 1944.

The ENIAC Mark I computer was the brainchild of John Presper Eckert and John W Mauchly in 1946.  The architectural design required the rewiring of the plug board to change its programming.  It was capable of adding and subtracting five thousand times a second, and had the added ability to perform, multiplication, divide and square root calculations.  It weighed in at thirty tons, used two-hundred kilowatts of power, and contained eighteen thousand vacuum tubes, fifteen hundred relays, and hundreds of thousands resistors, capacitors and inductors.

The Small-Scale Experimental Machine, also known as Baby, was completed in 1948 at England’s; University of Manchester based upon the stored-program architecture.  On the 21st June 1948, it made its first successful run of a program, using 32-bit word length and a memory of 32 words.

The Manchester Mark I, a more powerful machine was built to supersede the Baby with expanded size and power, using a magnetic drum for auxiliary storage.

Later that year, Cambridge University built the Electronic Delay Storage Automatic Calculator, which was fitted out with a built-in-program.

The Government requested Ferranti to build a commercial computer based on the design of the Manchester Mark I in October 1948.  The Ferranti Mark I, included enhancements making it more powerful and faster.  The first machine was rolled out in February 1951.

John Presper Eckert and John W Mauchly, who designed and built the ENIAC Mark I computer, updated their design in 1951, with the release of the UNIVAC, for use by the U.S, Census Bureau.  It used 5,200 vacuum tubes, and consumed some 125kw of power.  Storage was by way of serial-access mercury delay lines.

In the early 1950’s Sergei Sobolev and Nikolay Brusentsov two Soviet scientists designed the Setun, a ternary computer that operated on a base three numbering system, (-1,0,1) rather than the conventional binary numbering system.  The computer was used within the Soviet Union, but its life short lived, and the architecture was replaced with a binary system.

In 1952, IBM released their first Electronic Data Processing Machine; IBM701, and its first mainframe computer.  Then in 1954, the IBM704 came onto the market, using a magnetic core memory.  During 1955-1956, IBM developed the Fortran programming language, for use with the IBM704, which was released in 1957.

In 1954, IBM produced a smaller computer the IBM650, weighing in at 900kg and the power unit at 1350kg.  At the time of construct it had a drum memory unit which could hold 2,000 words, later increased to 4,000 words with a maximum of ten letters per word.  The IBM650 used; SOAP (Symbolic Optimal Assembly Program).

Microprogramming was invented by Maurice Wilkes in 1955.

Then in 1956 IBM created the disk storage unit; the IBM350RAMAC (Random Access Method of Accounting and Control).  It used fifty 24-inch metal disks, with one hundred tracks per side, capable of storing five megabytes.

John Presper Eckert and John W Mauchly, recognized the limitations of the ENIAC, even before construction had been completed in 1951.  They started researching the possibilities where programs and working data, could be stored in the same area, on the same disk, at the time this would have been considered rather radical.

Equipment of the mid-1950’s transmitted data by acoustic delay lines using liquid mercury or a wire.  It worked by sending acoustic pulses represent by a “1 or 0” causing the oscillator to re-send the pulse.  Other systems on the market at the time used cathode-ray tubes, storing and retrieving data on a phosphor screen.

The Magnetic Core Memory, where each core equals one bit, was created in 1954, replacing many forms of temporary storage, and would go on to dominate the market for many years to come.

The Bipolar Transistor of 1947 went on to replace vacuum tubes from 1955.  The early versions were the Germanium Point-Contact Transistors, consuming less power, but reliability was an issue.

The University of Manchester, built the first transistorized computer in 1953, and the updated version was running by 1955.  It used two-hundred transistors, thirteen-hundred solid-state diodes, with a power consumption of 150 watts.  Whereas the Harwell CADET, had no tubes it had a tendency to crash every ninety minutes, but by changing to a more reliable bipolar junction transistor, they found crash times were reduced.

Upon comparing vacuum tubes and transistors, the transistors had many advantages, being smaller in design, requiring less power, which gave off less heat.  Transistorized computers contained tens of thousands binary logic circuits in a compact space.

With the creation of transistorized electronics, we saw the Central Processing Unit, within would be the ALU (Arithmetic Logic Unit), which performed arithmetic and logic operations the first of many devices which would show enhanced improvements.

In a sense new technology had opened the flood gates to improved parts for the computer, where once they would have taken up the space of a large room, technology had seen them reduced in size, capable of sitting upon a table.  One invention would be the Data-Disk Storage Unit, capable of storing tens of millions letters and digits, alongside removable data disk storage units.  Input/output, a means by which a computer exchanges information.

Telephone connections went on to provide sufficient speeds for early remote terminals like the Teletype or Telex machine.

Who would have believed, that these stand-alone computers, one day would be the basis for the Internet.

Jack Kilby and Robert Noyce, designed the Integrated Circuit (Microchip) in 1958 which led to the invention of the Microprocessor.  Then in 1964 IBM released its Solid Logic Technology modules in Hybrid Circuits.

Intel opened its doors in 1968, and in their early days produced the semi-conductor memory, and went on to create DRAM and EPROM.  Intel developed their Microprocessor in 1971, and crammed an entire computer on a single chip.

They produced the Intel 4004, the first microprocessor consisting of 2300 transistors and clocked at 108 KHz.  They followed up with the 8008 and 8080 models.

Altair8080

Altair Computer

The 8080 was used in MITS Altair computer kit.  This machine attracted one Bill Gates a Harvard freshman to drop out of college and write programs for the computer.

Alan Shugart and IBM invented the Floppy Disk in 1971, and nicknamed it the “Floppy” based on its flexibility of use.

The idea of computers co-ordinating information between one another had been around for years, using telecommunication technology.  Then in 1973 Robert Metcalfe and Xerox created the Ethernet Computer Networking System.

Olivetti, a company more associated with typewriters, presented to the world, their first personal computer the P6060 in 1975.  It had a 32-character display, 80-column thermal printer, 48 Kbytes of RAM and used BASIC language, weighing in at 40 kg.

In 1991 Bill Gates and Microsoft, supplied the world with MS-DOS an operating system to run the computer.  That same year IBM released their home computer, and so the home computer revolution had started.

4.0.1

Apple 1983 Computer

In 1983 Apple released their home computer with a graphical user interface.  In 1984 Apple Macintosh released a more affordable home computer with graphical user interface.

In 1985 Bill Gates and Microsoft released their new Operating System which would revolutionise the computer for decades to come; Microsoft Windows, which has been upgraded over the years.  We have now reached Windows 8.

With the 1990’s came E-mail and the World Wide Web … and computers and the Internet would change our world for ever.

Typewriter Creation

Gutenberg Printing Press

John Gutenberg, a name that will go down in history, for he invented the printing press using a loose tile system in the mid 15th century.  The exact date is unknown, but it is believed to be around 1440.

The next stage in development would be a machine capable of impressing letters and numbers onto paper.

Typewriter

It was to be nearly three hundred years before; the early development of the typewriter would take place.

In 1714 Queen Anne of England approved the patent of an early typewriter design to inventor Henry Mill.

In 1808, Pellegrino Turri an Italian invented an early design of the typewriter, and took it one step further by the invention of carbon paper, as a means of ink supply.

In 1829, William Austin Burt patented his machine the “Typographer” but it was better known as an “Index Typewriter” as it uses a dial to select keys.

By the time the mid 19th century had arrived businesses needed communication, and mechanisation had become the word when it came to the writing process.  Inventions in this area were released, but none reached commercial production… For their ideas and practical uses did not pan out.

1843 – Charles Thurber patented the Chirographer.

1855 – Giuseppe Ravizza patented the Cembale Scrivano Typewriter prototype.

1861 – Father Francisco Joa de Azevedo built a typewriter from wood.

1865 – John Pratt patented the Pterotype.

1864/1867 – Peler Mitterhofer (de) patented several functioning prototypes of the basic design of a typewriter.

In 1865 we turned a corner, when the Hansen Writing Ball typewriter was invented by Rasmus Malling-Hansen of Denmark, and went into commercial production in 1870.  It was a successful design.

Early designs, attached paper to a cylinder, which was located within a box, by 1874 the cylinder had been replaced by a carriage.

In 1868 Christopher Scholes, Carlos Glidden and Samuel Soule of America invented a typewriter which was destined to become commercially successful.  Its patent was sold, and Remington & Sons commercialised the “Sholes and Glidden” typewriter.

Thomas Edison invented a “Universal Stock Tickler” in 1870, which printed letters and numbers on a paper tape, as used with the telegraph line.  For his basic idea coupled with Sholes prototype typewriter, attracted the attention of Edison himself, believing power would one day run the typewriter.

vintage_typewriter

On 1st March 1873, Remington produced its first typewriter using the QWERTY keyboard layout, which is still around to this day.

By the year 1910, the manual typewriter had reached a standard design, using inked ribbons for supply of ink.

1902 – Blickensderfer Manufacturing, released their electronic typewriter, but failed partly due to the fact, electricity voltage differed from city to city.

1910 –  Charles and Howard Krum filed a patent for their Teletypewriter, which used a wheel rather than type bars.  It became the first of its type to come into production, and was used by the Postal Telegraph Company on lines between Boston and New York.

1914 – James Smathers invented a power-assisted typewrited.

1920 – James Smathers produced a successful power-assisted typewriter based on his early design.

1923 – Northeast Electric Company developed Smathers design, using the typewriter and their electric motors into a commercial venture.  By 1925 Remington Electric Typewriters were powered by Northeast’s motors.

With Remington, not willing to place further orders for Northeast’s motors in their typewriters, as they were in talks in the creation of a new company: Remington Rand.

Delco, a division of General Motors, bought Northeast Electrics in 1928, thus creating Electromatic Typewriters which was sold to IBM in 1933, who in 1935 released the redesigned Model 01 Electric Typewriter.

In 1941 IBM released Model 04, with a new dimension in typewriter design.  It contained proportional spacing, which was enhanced by the use of a typewriter ribbon.

In 1961, IBM’s development had changed much since the early days of the typewriter, with the release of the “Selectric Typewriter.”  For out went the type bars, and moving carriages, and in came a sphere with characters, numbers and punctuation symbols fitted on a metal rod.

The “Selectric Mark II” was released in 1971, with pitch control and a ribbon housed within a cartridge and by 1973, it also contained an erasing tape.

1974 the “IBM Memory Typewriter” came into production, giving the user the ability to save and recall their work, and by 1977 they introduced the “Memory 100 Typewriter” which included a 100 page built in memory file.

The electronic typewriter was replaced by the Word Processor, with its own screen, spelling and grammar checkers, and removable storage devices, with a daisy-wheel mechanism by the early part of the 1980’s.  As sales plummeted IBM got out, selling its typewriter business to Lexmark in the 1990’s.

Who would have believed in the early days of typewriter design that people would type at lightning speeds or have capabilities of storing 100 pages of memory text?

So the typewriter and word processor market would give way to the rise of the personal computer, and so technology moves forward…

Printing History: Augustus Applegath

Applegath Bank Note Print

Applegath Printed – Bank Note

Augustus Applegath was born on the 17th June 1788 in the Parish of Stepney in East London.  His father was a sea captain, who worked for the East India Company.

From an early age, Applegath showed an interest in that of finding out how things worked, which would lead him to become an inventor in his time.

He will be remembered, for an invention, the brainchild between himself and his brother-in-law creating a double-sided printing press, known as the “Applegath and Cowper Royal.”

Applegath caught the attention of the “Bank of England,” and in 1818 they allowed him to print £1.00 and £5.00 forgery proof notes.  Millions of £1.00 notes were printed, but none were released to the general public.  The idea being that paper as a medium had been used and that William Bawtree of the Bank could produce reasonable copies, even in the six colours of Applegath’s version.

The project was cancelled, and Applegath and Cowper received £4,000 in remuneration for the time spent on this venture, and neglect in their other business interests.

Applegath designed a printing press for “The Times” which would be capable of printing some 5,000 newspapers an hour.  The first version reached its target of 5,000 and the four-feeder version introduced in 1846, saw “The Times” print a daily circulation of some 28,000 copies.  Then in 1848 the newly improved eight-feeder version was able to print 8,000 copies per hour.

His inventions did not stop there, for he invented a successful method of silk printing, by using curved copper plates rather than traditional handblocks.

Not all of his inventions were successful.  For it was in 1848 he built a traction engine which was road tested.  On one attempt it landed in a ditch, and he was so disgusted with it, that he left it there, gathering rust.

Augustus Applegath died on the 9th February  1871 aged 82, knowing his inventions would help those following up behind.

Printing History: John Baskerville

John Baskerville

John Baskerville

John Baskerville was born on the 28th January 1706 in Wolverley, Worcestershire, England.

From an early age, he loved to see beautiful lettering in written works, this passion would take over his life, and by 1723 he had become a skilled engraver.  His early engravings were upon tombstones, and from there he moved forward.

Around 1725/26 he moved to Birmingham, and became a writing master by 1738 adding new innovations to his skills, such as early forms of enamelling.

In 1750 set-up his foundary and printing works and experimented with typography, paper-making and ink manufacturing, and in 1754 produced his first ever typeface.

In 1757, printed his first book, “Virgil” and in 1758: “Paradise Lost by John Milton.”  He showed his true abilities in the printing world, and was duly appointed printer to the University of Cambridge, where he printed “Book of Common Prayer” and the “New Testament” in a Greek typeface.

John Baskerville and Benjamin Franklin created a lasting friendship as fellow printers only separated by the waters between their two countries.

John Baskerville left for his successors new innovations in the art of printing, paper and ink development.  He created a smooth white quality paper to showcase his Baskerville Typeface in a strong black colour with improvements in ink type and colour.  His style of typography changed the way text appeared upon paper, with wider margins and line spacing.

John Baskerville died on the 8th January 1775 aged sixty-nine, but his burial was not straight forward by any means.  Under Church law, as a confirmed atheist, he could not be buried on holy ground.

Therefore he was buried in a mausoleum erected in his garden, and upon the death of his partner Sarah on the 21st March 1788 the house was sold.  In 1791 John Ryland moved in, and left it to his son Samuel upon his death, who bequeathed it to Thomas Gibson.  Part of the land was turned into a wharf with a canal, which resulted in the destruction of the mausoleum, with Baskerville’s coffin left buried underground.

In 1821, the coffin was discovered, and placed in storage at Gibson & Sons until 1829, then moved to John Marston’s Shop (Plumber & Glazier).  An application was made by Marston to move Baskerville’s body to his family vault at St.Philips Church, but the request was denied by the church.  Yet the body was moved to Mr.Nott’s family vault at Christ Church, a friend of Marston’s without the permission of the church.

In 1892, Talbot Baines Reed, started a search for Baskerville’s body, and upon discovery at a vault in Christ Church, had it cemented behind bricks.

Some years later all coffins held in vaults were removed and interred in the Church of England cemetery in Warstone Lane, within a vault, located under the chapel.  Later the chapel was demolished and the entrance blocked up forever.

John Baskerville became famous in life as he did in death.  I wonder what the man himself would have thought about being carted here and there all because of his beliefs.
