Ralphie’s secrete message , from The Christmas Story, that he received from the Ovaltine decoder pin looked challenging and difficult at first but soon was able to decode the very important message. However, if his message from Little Orphan Annie was coded with the Enigma machine it may have been more puzzling for Ralphie just like it was for the rest of the world.The Enigma machine was a complex machine that was used by the Nazis during World War II to send secret messages. This machine consists of three routers , two keyboards, and a plug board or coming together to make an intricate machine for its time.Germany believed this machine was unbreakable and that their messages would never be decrypted. This machine may have helped Germany in …show more content…
When the rotors turn, the battery will be connected to a different bulb lighting up a different letter each time . If “A” is typed in once it may appear as “Q” but then if it is typed again it may appear as a “R”. This is all due to the turning rotors and the criss cross wires completing the circuit in a different way each time.To add to the complexity of the code the electriacal circiut is not sent though the rotors once but twice with the use of the reflector. The reflector basically takes the letter it was given after it went though the fist time of rotors and sends it back out as another letter and then that letter goes through the rotors again. After the electrical current went through the rotors twice it will go down to the plug board again. So if our initial letter of “T” comes back out of the rotor as “Q” the “Q” will continue down to the plug board and switch with whatever letter “Q” is matched with.The final result of this one press of the letter “A” could come out as ,for example, as “K”. Overall this may seem a little complex but this machine is just a basic circuit that with moving parts inside (Cipher
Imagine a staged production of A Christmas Carol set in 1843. See the stage set in the exact time it was written by Charles Dickens. The foggy, crowded streets abuzz with carolers and shoppers, the children staring wide eyed into the shops and bakeries. Hear the bells ringing as a round of “Hark the Herald Angels Sing” fills the gaslit streets with joy. As a child, going to see A Christmas Carol was one of my fondest Christmas memories. To witness Scrooge 's’ transformation from a mean, greedy old man to a joyous, loving benefactor always left me smiling and filled me with hope.
“I am not the man I once was…” (Dickens 675) might be the most famous words of Ebenezer Scrooge in “A Christmas Carol” Written by Charles Dickens. Ebenezer Scrooge is a horrible man who is haunted by three spirits overnight in hopes to make a new man out of the old miser. Throughout this story, Ebenezer Scrooge is haunted by three spirits ,Christmas present, past, and future, and during this time he learns about his greed, what joy he missed on christmas, and that he had a chance to become better.
When a fellow general received the message, he would wrap the paper around his corresponding scytale to decipher the message (Tyson 2014). Since the advent of computers though, encryption has become increasing important and relies almost solely on cryptographic means to secure information. When speaking about encryption today, it refers more to the process rather than the mathematical formulas used to scramble data. The basic idea behind encrypting a computer message is such that it is scrambled with a sequence of random bits, known as a key, and only parties with the corresponding key can transpose it back into a comprehensible format. These keys are created via a cipher, otherwise known as an algorithm. When a user sends a message, known as the plaintext, across a network, the computer applies an algorithm to the information to encode it, resulting in a ciphertext (Encryption Basics 2014). This method can be best summarized visually:
The novels A Christmas Carol, by Charles Dickens, and Wuthering Heights, by Emily Bronte display a strong parallel in the ways in which they use their different styles of narration in the story to reveal the true inner-feelings of characters. In A Christmas Carol, the main character, Ebenezer Scrooge, is taught many valuable lessons through the testament of three different spirits, each working to bring out the true emotions of this man. Likewise, in Wuthering Heights, the main character, Mr. Lockwood, is taught stories of his landlord, Mr. Heathcliff, through written recollections from the testaments of others, showing the inner-feelings and thoughts of him through diary entries. Although they are written in two different styles, indirect
marriage and gender roles. In the case of A Christmas Carol, Charles Dickens wants readers to see how living a life that radiates love and promotes happiness is better than being selfish and living a miserable life, and how past circumstances heavily influence who we are as people. The two messages both authors want readers to take away from the story, although different, achieve the takeaway through the utilization first person narration.
5 remarkable British scientists had gotten their hands on an actual Enigma machine smuggled out of Berlin. They had put tremendous effort into decoding the Nazi's messages by using their cryptanalytic abilities but had failed because of the lack of information on the machine's
A Rube Goldberg machine is a device, invention, or creation used to perform a simple task. A simple machine is any of the basic mechanical devices for applying a force, such as an inclined plane or lever. If several simple machines are put together to cause a reaction, like turning on a record player, then the music will turn on because the energy transfers through all the simple machines eventually causing a string to be pulled turning the knob. One Rube Goldberg machine created was created to turn on a record player. The record player that was used required a knob to be turned. The first few attempts did not have the result wanted. Several changes were made to the machine to assure the outcome would be positive. Simple machines can be found
The cipher disk dates back to the Civil War, when it was used by both the Confederate side (CSA stands for Confederate States of America) and the Union side (the initials A.J.M. stand for Union Chief Signal Officer General Albert J. Myer). The goal of this invention was to provide a way for people that were in signaling distance of each other to communicate by deliberate movements of flags or other objects. It also utilized a secret arrangement of letters and numbers. It was about three and three-fourths of an inch to four inches in diameter and was usually made of wood or a thick, durable, paper-like material. It had two disks of different sizes that revolved on a central pin. The disks were divided along the outer edges into thirty equal
Scrooge plunged into his grave,down he vamoosed into the abyss of which was his own. CRACK, it seemed like it was all just a dream a myth,imagination,nightmare all just fantasy.Scrooge was happy as a little donkey on a summer day that yells out “i'm still alive”. As he wandered what day it was, he darted his way out his window and spotted a young man dragging his sled. “Hey what’s today” Scrooge said, “eh” says the young man,”whats today my fine fellow”said Scrooge with a happy chuckle.”Why it’s Christmas day”, “the spirits did it all in one night said Scrooge. Scrooge told the boy if he would go the poulterers shop down a street and buy a big prize turkey,come back in less than five minutes and i'll give you half a crown! The boy ran as fast as he can to the shop, Scrooge threw himself down the stairs and greeted Mrs.Dimber a merry Christmas.

One of the main characters was Ebenezer Scrooge. On Christmas Eve Ebenezer Scrooge was haunted by three spirits the names were spirits Christmas Past, Present, and Future. Scrooge change through the three spirits. Scrooge did not like Christmas but in the end, he was very giving.
During World War 2 was a time of devastation. It was also a great time of innovation. One of the greatest innovations was the beginning of modern computing. During World War 2 encryption was each army’s main way of keeping war plans secure. One of the most famous encrypting machines was named the Enigma. The Enigma was a machine that took input from one side; encrypts it and sends the message to another operator who then translates it using a code book (Gladwin). Using this machine, the German’s kept nearly all the information secure from other countries. To break these encryptions, the British secret service along with many other countries started to build machines that could defeat the Enigmas encryption (Gladwin). Soon after the Germans
Throughout the novel A Christmas Carol, many themes can be chosen to describe the book. While Ebeneezer Scrooge is looking at what the future beholds for him and his peers, he realizes because of the choices he made during his life, people are not going to miss him. Scrooge realises that people will not care when and if he dies, and they definitely will not spend much time morning over his passing. Through the Ghost of the Future, Dickens is explaining that success does not equal money.
When reading A Christmas Carol by Charles Dickens you realize that Scrooge’s childhood has a huge impact on his adult life, his adult self is a mirror image of his child self, both in his emotions and relationships. This becomes apparent when the ghost of Christmas past appears and takes Scrooge on a journey back into his childhood days. His childhood really molds Scrooge into the person he becomes later in life.
Samuel F. B. Morse perfected the telegraph in 1832. A telegraph is a device that sent information to somewhere through wires. He studied magnetism and electricity. Later he put other scientists work together in a certain machine which was the telegraph. The telegraph could do many different things. Some of the things that it could do was send pulses and surges. The telegraph had a telegraph key. The telegraph key controlled how long each pulse is. When it got to the end of the wire it turned into clicking sounds, like a dot. If you were very good at working with the telegraph you could send and receive messages a lot of words per minute. There were different sounds that the telegraph could make and each sound was a different letter of the alphabet
“Why is he not here yet? He should be here by now.” Sparsit said, worried. “You actually worry about him? The way he treats you? Treats us?” Cook said. “Well… I don't know. I mean, maybe if I act worried, he may feel it in the air, and give me Christmas off. All I want for Christmas, is to be off, solely to help people in need,” Sparsit said, yawning. “I’m going to check if he has arrived.” Walking to the door, Sparsit hears a noise, so he peaks out. Without hesitation, Sparsit opened the door to let Mr. Scrooge in. Startled, Scrooge said “Sparsit?” “Yes, sir?” Sparsit replied as if it was uncontrollable. “Hurry, hurry. The door… close it.” Scrooge said, causing Sparsit to think. “Did you knock, sir?” As he said that, Sparsit knew he had messed
