IS ANYBODY ALIVE OUT THERE OTHER THAN ME AND IRENE?!! WHY IS NOBODY POSTING OR COMMENTING ON MY AWESOME 651 WORD BLOG POST LAST WEEK? Grr, Irene, you BETTER bring me some of that candy…I mean it…And I do not care how long your blog post is. Do you not love the lovely graph I…
Binary tree flower, liquidx, flickr, (CC) BY – NC – SA 2.0 Hey people! Surprise! We learned math last class! See ya! Just kidding…. Well, on second thought, this statement is true, though. We DID learn math last class, because this is a (dramatic pause) math class! Okay, seriously now, what did we specifically learn…
Math Dances, Dylan 231, flickr, (CC) BY 2.0 Not really relevant, but very funny. Like I said, I had a school field trip last Thursday and could not attend. Sorry. I know you guys all missed me and found the class incredibly boring without me. And Cecilia, believe it or not, I miss having you…
This picture of me receiving my award (see second to last paragraph) was taken by Cecilia’s dad. Thanks, by the way! Xie xie! Hi! Like I predicted, we learned more cryptology this week, moving into the more interesting and tedious deciphering part of cryptology. We learned about polyalphabetic ciphers and Index of Coincidences, too. We…
HY-2 Vocoder, brewbooks’ photostream, flickr, (CC) BY-SA 2.0 Sign reads: First widely deployed device for converting speech into a form compatible for encryption by a general purpose key generator (KG-13) for transmission over narrowband radio and telephone. Affectionately compared to Donald Duck’s voice. Vietnam War era. Hi, amateur cryptographers! Wow, once again, I am the…
William Friedman bust, austinmills, flickr, (CC) BY-SA 2.0 The ‘person’ on the left, by the way, is William Friedman, the father of cryptology. Hi everyone! Last week, we started a new unit on cryptology, the science of encrypting and decrypting information. It is unit X! (It is not X as in the Roman numeral X,…
Identity Matrices, faith_wicks, flickr, (CC) BY-NC 2.0 Hi, math class people! This week, I learned (back to generic openings) about matrices and Markov chains, named after Andrey Markov. Specifically, the kind of matrices that we covered are known as transitions matrices. These matrices can be used to analyze transitions between different states, like in games…
Jean Bernoulli, Stifts- och landsbiblioteket i Skara, flickr, flickr, (CC) BY-NC ND 2.0 Hi, Grammar Nazis and Non-Grammar Nazis! (I am sure you know where you fall in these two categories.) For a change, the material that was covered in class this week was easy to understand and learn. It was the homework that drove…
Bayes theorem, disownedlight, Flickr, (CC) BY-NC 2.0 Caption written by author: “Bayes theorem Where e is evidence, H is hypothesis, and P() is probability. There is a lot to think about in this simple theorem.” Hi, non-procrastinators and procrastinators of my super smart math class! Main theme: Probability was the main theme of what was…
Pascal Triangle, Ethan Hein, Flickr, (CC) BY-NC-SA 2.0 I will try to make sure that all of my sentences are grammatically correct to prevent certain people (one who worships clouds and one who is fanatic about sporks) from debating over the sentences. Honestly, I feel so sorry for that poor sentence. (See Xiaolu’s Reflection Week…
