week 4 prompt

They have a man by the name of Petros Petrosyan who is a famous cipher and who has solved the great pyrmid cipher that remained unsolved for so many years. This is a cipher code on how to pyramids are so closely connected with the way of problem solving today and how they connect with the modern day math of ancient egypt. It has a great amount of geometry within the codes and how to slove them. I think that the reason for this is because it was something that was built and geometry is the foundation of all the building supplies needed in life. I dont think that it has related to anything that we have learned this year but I think it does have something to do with what we learned in Geometry.

  1. Arnold Cipher:In May 1779, Continental Army Major General Benedict Arnold initiated what became a series of communications with British Army Major John André, the adjutant and spy chief to Lieutenant General Sir Henry Clinton, the commander-in-chief of British forces in North America. In these communications, which were at first mediated by Joseph Stansbury, a Philadelphia merchant, Arnold offered his services to the British. André responded to this offer with a letter dated May 10, 1779, in which he described the types of services Arnold might provide, and described a code which they should use to obscure their communications.[1]

    The book used as a key to the cipher was either Commentaries on the Laws of England by William Blackstone or Nathan Bailey's Dictionary. The cipher consisted of a series of three numbers separated by periods. These numbers represented a page number of the agreed book, a line number on that page, and a word number in that line. Arnold added missing letters or suffixes where he could not find a match in one of the books.[2] For example, 120.9.7 would refer to the 120th page, the 9th line on that page, and the seventh word in that line, which, in the following example is decoded as "general".

    The actual communications was often disguised by embedding it in a letter written by Arnold's wife Peggy, where the cipher would be written in invisible ink, but might also be disguised as what appeared to be routine business communications.
