    Ughh… Haifa Vector 

    Which topic/s in class made an impact to you? Why?
    Baasiiiss! Hahaha it is our final project topic, and we won two awards! It was fun making the video. I learned that Michelle Scalar can’t be stopped (I’ll get back to you, buddy). Anywaayyss, yes, basis. its application is coool. Remeber that change of perspective photo? AMAZZEEENNGG!

    If you can summarize this course in one word or sentence, what would it be?
    HAAAAHHH ~(‘.’~) (~’.’)~

    What would be your parting message to the class?
    See you arouunnd mahfreennss ❤ THESISING NA NIYANN HOHOHO! Good luck sa atin! Let's enjoy the coming years, yes yes yes! \('.')/ \('.')/ \('.')/

    OMG SIR PAUL SEE YOU AROUND 🙂 CONGRAATTSSSS HIHI Very inspirational parting wooords. I'm glad I took your class!

    Fourier Transform in Painting Authentication 

    Authenticating paintings has always been a problem in the art world especially during auctions. Usually, they rely on the opinion of art historians who specialize in that artist to determine a painting’s authenticity. Now, with Fourier transform, they are able to analyze the painting with certainty. After scanning the picture for a digital image, they convert it to a Fourier transform to filter useful information that would help them identify the painting’s elements. They are able to analyze the painting’s brushstrokes and compare it to an original artwork to determine its authenticity.

    Cancer Factor: Symmetry 

    “Symmetry has always been an important part of our biological make up… It is an indicator of health, fitness and performance”(Scutt).

    Symmetry is a good measurement for body development since it provides a comparison on how a body part grows. There are many factors like hormone secretion that disturb symmetrical body development. For example, the rapid growth rate of breasts make them more susceptible to mutation. The researchers at the University of Liverpool found that symmetry can be a factor to indicate breast cancer since it can show “an individual’s ability to tolerate ‘disruptive’ hormonal variation” . Women who have less symmetrical breasts had a higher probability of developing the disease.

    Time as a vector 

    …but hey time is scalar!

    I was browsing topics related to real-life applications of vectors when I stumbled upon the free-space diagram of a simple pendulum. And when you think of a pendulum, the next thing that comes in to your mind is…what? Yes, that’s right! A clock!

    So before I even realized what I was searching on Google, I have already typed “vector quantity application in clocks .” It makes no sense but that is how I saw this interesting Quora question- “Why are we looking at time as scalar and not a vector, do you know of a method to display time as a vector?” And surprisingly, someone answered that it is indeed possible to measure time as a vector. Specifically, it is possible through the Minkowski diagram which is used for Einstein’s theory of special relativity. So what is this all about?

    Time is absolute. Space is absolute. One hour for you is the same as an hour for me. One meter for you is a meter for me. But what if…

    You are walking by the sidewalk when you see a car pass by. Assume that the car is moving equal to the speed of light, and you are walking half as fast. You say that the car is moving twice faster than you, but for the person inside that car you are seemingly walking half as fast. This is a contradiction since we know from our Physics class that the speed of light is ALWAYS equal to 3×10^8m/s wherever we are. But how is it that the speed of light could be twice as fast or half as fast? Well…

    They say that when you are enjoying what you are doing, time flies by fast. And when you are bored, it goes oh so slow. Taking this into account, we can think that time is relative depending on our reference.
    Now, Physicists thought of combining time and space into “one continuum of spacetime” where in time and space are not absolute. Now we say that a time for you is not the same time for me. And a meter for you is not a meter for me.

    There are a lot of technicalities happening here so if you want to know the details, you can watch the source video below.

    So where does time as a vector come in to play?
    By graphical representation we can see that there a lot of time and space axes plotted over each other depending on the frame of reference. But still, we measure time in seconds, and space in meters. But since they are now contained in spacetime, we can measure both as one unit. Time can now be represented in meters since 1s*3×10^8m/s = 3×10^8m, and space can be measured as seconds!

    And that’s it! I don’t want to go blabbing about the really technical stuff since I am not well versed in this theory. And I am not even sure if i understood it correctly (so do tell me if there are any mistakes.)

    Hallo hallo! I am Haifa Gaza, a 3rd year BS Computer Science student!

    I am currently taking up the course Mathematical Methods in Computer Science… (Do you see that course title? It gives me shivers). Honestly, I didn’t have any thoughts regarding this course. I took it because I had to take it after finishing my Math series. I didn’t even know what it was seriously about before. Good thing our Professor showed us an interesting TEDxStandford video to motivate us. *poof inspiration* That should keep me going for the rest of the semester. (or not … this is Math we are talking about…)

    The title itself screams MATHEMATICS… I thought that if my grades in Math were a graph, it would probably be something like an ugly parabola with a vertex at (5,0). I know that to pass a Math course, I need extra EFFORT for practice, practice, and exercisessssssss. And I know that not all efforts are paid off that is why Math and I are in a love-hate relationship.

    It’s just that I really am hoping for a good semester. Somehow I shifted back to feeling that I need to get higher grades to prove myself to myself. Others can do it, why can’t I?
