    Bye 130 

    1. Matrix. Most of the topics in the class involved matrix and it really made me understand the topic more than I ever did. I also learned about its applications that I didn’t thought of.
    2. Happy 🙂 After a stressful day of classes all day, i’m thankful it ends with CS 130. Masayang may surprise games and interactive learning before and even in the lecture tapos very welcoming ang atmosphere sa class. Lagi rin nagtatawanan kahit lecture at isa sa pinakamagandang paraan to learn while having fun.
    3. Thank you sir Paul!! Thank you rin sa mga seatmates/groupmates ko. It was fun. SIR 131 naman!!! 🙂

    Seismic research uses Discrete Fourier Transform (DFT) and the Fast FT(FFT). If you look at the history of the FFT you will find that one of the original uses for the FFT was to distinguish between natural seismic events and nuclear test explosions because they generate different frequency spectra.

    The (fast) Fourier transform is used to convert the signal into the frequency domain, where convolution between two signals is obtained simply multiplying them together. Once again the Fourier Transform is used as a tool in Digital Signal Processing to perform other operations, rather than producing an end result itself.

    Symmetry in solving Rubik’s Cube 

    Solving Rubik’s cube often involves symmetry. When solving for a colored pair, there are same symmetrical moves that can solve the pairs that are in different phases.

    The example cases above can be solved in the same pattern in different axis that is actually a rotation or reflection of the other pattern.

    Intro to Me 

    Week 1: Introduce yourself

    What’s your name?
    Hi, my name is Paulo Gabriel A. Santiago. You can call me Paulo.

    What were your thoughts when you enrolled in this course?
    My first choice to enroll this semester was actually CS 133 but then I was advised to take up CS 130 instead since it’s a prerequisite of CS 131. When I think about CS 130, I think about deeper math, CS subject BUT more Math. I’m interested/scared about how this subject goes.

    How comfortable are you with math?
    I’ve always had a good understanding of Math. I enjoyed algebra in elementary and high school and thankfully, I attained good grades. In college, I studied with the same pacing as when I was in high school and it wasn’t really a good pace. I only study whenever needed or when an exam is coming so I didn’t have good grades. Nonetheless, I still enjoyed it.
    My study habits were too lazy that I failed my first Math 55 take. Maybe it was partly because my professor wasn’t as good as I wanted her to be but it’s mostly because I was REALLY lazy. So I took Math 55 the next midyear and I really tried to focus and study well because I wanted to prove to myself that I can excel with enough effort. Thankfully, I got an uno :)))) and I really understood the topics and enjoyed the subject as well. I did well with Math 55 then but I’m a forgetful person so I may need to brush up on my calculus and other mathematical stuff.

    What’s your dominant feeling right now?
    I’m feeling positive. It’s the start of a new semester. I never really did well last semester, at least to my standards, so I’m hoping to be better and more focused now that I have more major subjects than the previous semesters.
