In other words, the measured gray values of pixels that contain Archimedes text are approximately the same as those from the surrounding parchment when viewed in red light, so they cannot be distinguished. The second figure has an unknown mass, but the position of its center of mass might be restricted to lie at a certain distance from the fulcrum by a geometrical argument, by symmetry.

From Wikipedia, the free encyclopedia.

This thirteenth century prayer book contains erased texts that were written several centuries earlier still. Image processing and display Based on the results of the first phase, the imaging goal was modified to enhance the contrast of the original undertext while retaining visible overtext.

In addition, after disappearing from the Greek Orthodox Patriarchate’s library, a forger added copies of medieval evangelical portraits in gold leaf onto four pages in the book in order to increase its value, further damaging the text. A team of imaging scientists including Dr. The answer is 17, combinations. The Method of Mechanical Theorems also referred to as The Method is a work by Archimedes which contains the first attested explicit use of indivisibles sometimes referred to as infinitesimals.

One team, from the Chester F. The manuscript sold at auction to a private collector on the 29th October Some pages of the Method remained unused by the author of the palimpsest and thus they are still lost.


Three color images of each bifolium are sent to each scholar; those taken under xenon strobe illumination and ultraviolet light, plus the result of the pseudocolor image processing.

We noted that the two texts could be segmented fairly well by using a simplified collection and processing algorithm that did not require supervised classification.

The Archimedes Palimpsest

Each complete bifolium is imaged in ten overlapping sections. If you find two sequences U and L, with U always bigger than Q, and L always smaller than Q, and if the two sequences eventually came closer together than any prespecified amount, then Q is found, or exhaustedby U and L.

Particularly for the electronic copies, this rapidly became impractical due to the large volume of data. The most remarkable of the above works is The Method, of which the palimpsest contains the only known copy. The tungsten-red image with “bright” Archimedes text and “dark” Euchologion text is placed in the red channel, and the ultraviolet-blue image with both transslation visible is inserted in the blue and green channels. The resulting processed images are combinations of images taken at the different wavelengths and appear to be blurry.

The original goal was to “strip” archi,edes the later writings of the prayer book, leaving the original writings. Before that it was not archimeses known among mathematicians, physicists or historians.

The original plan was to distribute the processed images as printed copies on paper and as electronic images on cd-rom. Using multispectral imaging and an x-ray technique which picked up the iron in the ink that had been scraped away, they discovered that Archimedes, working in the third century BC, considered the concept of actual infinitysomething thought to have only been developed in the 19th century, and anticipated calculus.

All the raw imaging data, as well as transcriptions of the tranlsation texts in the manuscript have been published on the web. But the center of mass of one figure is known, and the total mass can be placed at this center and it still balances.


Using this camera, we can easily obtain images with a spatial resolution of 25 pixels per mm dpi.

The manuscript currently belongs to an American private collector To facilitate this process in conjunction with the standard method, a second camera head has been added to the x-y translation table. The Archimedes PalimpsestVol.

Archimrdes combinatorics reveals that the number of ways to place the pieces of the Suter board to reform their square, allowing them to be turned over, is 17,; the number is considerably smaller — 64 — if pieces are not allowed to be turned over.

It originally was tranxlation 10th century copy of an otherwise unknown work of the ancient mathematician, physicist, and engineer Archimedes c. The Archimedes Palimpsest is, then, a document of great cultural significance. The Archimedes Palimpsest is a parchment codex palimpsestwhich originally was a 10th-century Byzantine Greek copy of tdanslation otherwise unknown work of Archimedes of Syracuse and other authors.

When Heiberg studied the palimpsest in Constantinople inhe confirmed that the palimpsest included works by Archimedes thought to have been lost.

But then something even more extraordinary happened. The wavelength band transmitted by the lctf can be “tuned” electronically over a range of visible wavelengths from nm to nm; the passband is approximately 10 nm wide. Iron gall ink was used for both texts in the manuscript.
