Instead of teaching us calculus, our math professor taught us something new out of the box. Last August 25, Sir Jamosin taught us how to decipher codes using different ciphers. After discussing the algorithm of the system, he gave us a challenge to decode something and promised to give us extra plus points in the exam if we will decode it and do the task stated. Scribbled in the piece of paper is the following:

Using the Virgenere cipher, which I wouldn't discuss in this post, we were able to get the true message out of the random letters above which obviously is grouped by 5. You can search it in google to find out how the Virgenere Cipher works. Well, after a couple of hours, we were able to unlock the message and do the task given.
Below is the transformed message:
I have a dream that one day this nation will rise up and live out the true meaning of its creed. We hold these truths to be self-evident that all men are created equal. I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slave owners will be able to sit down together at a table of brotherhood. Have a dream that one day even the state of Mississippi, a desert state sweltering with the heat of [give me a video of your group shouting "I love math 54" at the sunken garden] injustice and oppression will be transformed in oasis of freedom and justice . I have a dream that my four children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have dreamt today. [qqq]
Analyzing and deciphering codes and ciphers is quite interesting. :)
