    SEE YOU WHEN I SEE YOUUUU 

    • Which topic/s in class made an impact to you? Why?
      • Laplace and Fourier Transform and Vectors made an impact to me in class, especially when I am researching for the journals. I realized that we are really inded use complex mathematics like these in our everyday lives. Math is around us. It can be found and used in the simplest things like when you are asking for directions and it can also be applied in complex things like MRI. After CS 130 I learned how to look for the hidden mathematical complexities of things.
    • If you can summarize this course in one word or sentence, what would it be?
      • MATHEMATICS
    • What would be your parting message to the class?
      • THANK YOU FOR EVERYTHING!!!
      • MARAMING MARAMING SALAMAT KAY SIR PAUL DAHIL FOREVER AWESOME AND KIND AND THOUGHTFUL NIYA TALAGA SA MGA STUDENTS NIYA HUHUHU Thank you very very much for being that kind of prof to us, a prof who has the heart for his students. (sobrang nafeel ko yun nung minove ni sir yung deadline nung video ❤ )
      • THANK YOU SA FUN AND CHILL KONG CLASSMATES, SEE YOU AROUND GUYS!!!!
      • sorry din pala dahil medyo butaw ako sa class na ito pero nevertheless IT WAS AN AWESOME CLAAAAAAAASSS!!!!
    • CONGRATS DIN PALA KAY SIR PAUL FOR HAVING ANOTHER SUCCESSFUL SEM OF TEACHING AAAAAAANNDDD PATAPOS NA SIYA SA THESIS NIYAAAAA ❤ ❤ ❤

    Fourier Transfrom in MRI 

    “Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases, MRI gives different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan.”[1]

    The signals retrieved from a Magnetic Resonance Imaging (MRI) scan are “a combination of signals from all over the object being imaged.”[2] As we learned in class signals are composed of sine waves with different frequencies. The Fourier transform allows us to understand and interpret those frequencies and amplitudes. “It converts the signals from the time domain into the frequency domain and if we can separate out the frequencies we can say where we should plot the amplitudes on the image.”[2]

    "Netflix and Ch– Vectors" 

    Apparently, Netflix uses vectors to build a specific and unique recommendation list for each user. It’s like Netflix creates a user vector where it stores all of the rating records for all the shows/movies that a user watches there.

    here’s a good blog article where you can learn more about Netflix’s usage of vectors for recommendation 😀

    R E B I R T H 

    Art is a medium where people can express their creativity and skills. There are many important concepts and techniques that you need to consider when creating AND observing art. One of those techniques is SYMMETRY.

    I picked several Early Renaissance paintings by Pietro Perugino as examples. As you can see in the painting examples below. Perugino loves using techniques to give depth, balance, harmony, and symmetry in his works. In the images below, the managed to emphasize the middle focal point in his paintings by making objects symmetrical like the buildings in Christ Handing the Keys to Saint Peter (1482) and Marriage of the Virgin (1500). Meanwhile in almost all of the examples below, you can see the number of people and their distribution are symmetrical. Even the way they are placed and the orientation of their body are also  balanced.

    These are only a few examples on how art can be symmetrical and balanced even in subtle ways. :>

    P.S. credits to my FA 30 prof for introducing to Renaissance Art, super worth it ing AH GE class na ito ❤

    Hello, it’s Camille ;) 

    • What’s your name?
      • Camille Francene Aberin Razal but you can call me Camille 😉
    • What were your thoughts when you enrolled in this course?
      • Sana nag-aral ako ng Math 55 nung bakasyon and  Yes!!! Sir Paul ulit ❤
    • How comfortable are you with math?
      • We have a love-hate relationship but I hope that we get along for CS 130 :>
    • What’s your dominant feeling right now?
      • HAAAAAAAAAAPPY and EXCIIIITEEEED!!! pero kinakabahan din dahil heavy load ko this sem and Engg Week this sem so sana maalagaan ko pa rin acads ko hahaha
