    RREF was the most impactful topic for me because I really hard a time time learning it and doing it properly. It felt so satisfying to be able to answer RREF problems since I studied hard how to do it and I could see that it paid off.

    FUN. CS130 was a class that I always looked forward to attend. It was fun not only for the games before the start of the class, but also for the discussions. The discussions weren’t dull which made it easier to learn the topics.

    Hope to see everyone in CS131!

    Moment (probability) and Laplace transforms

    First what is a moment? In statistics, a moment is a specific quantitative measure of the shape of a set of points. Now, here’s how the Laplace transform aid in probability.

    The Laplace transform is a holomorphic function. A holomorphic function is a complex-valued function of one or more complex variables that is complex differentiable in a neighborhood of every point in its domain. This means that its domain includes complex numbers and that there exists a complex derivative for the function. A holomorphic function is infinitely differentiable and equal to its own Taylor series. As a holomorphic function, the Laplace transform has a power series representation. This power series expresses a function as a linear superposition of moments of the function. This perspective has applications in probability theory.

    Symmetry in our senses 

    Having 2 eyes enables us to have stereoscopic vision. This gives us the ability to see in 3D! Each eye views our surroundings at a slightly different angle which results in 2 slightly different images. Our brain combines the two images by matching similarities and filling in the differences. The final image results to a view that has depth.

    Having 2 ears gives us binaural hearing. This makes it easier for us to know the direction of sound. It gives us the ability to hear farther as well as the ability to hear better. Hearing from one ear doesn’t stimulate our brain equally which results to a less balanced sound and uneasiness. The sounds we hear are also divided equally which help when in a loud environment as well as sudden loud noises.

    Roller Coasters! 

    No engines are mounted on the cars of roller coasters! The movement of the cars are due to the Earth’s gravitational pull. Here the calculation of the vectors of forces, velocity, acceleration, and friction ensure the safety of the riders.

    What’s your name?
    Hi I’m Arthur Yiu! You can call me Arthur 🙂
    What were your thoughts when you enrolled in this course?
    Sana mabilis ko matutunan yung lessons para pumasa ako in my first take hehe.
    How comfortable are you with math?
    Not at all 😦
    What’s your dominant feeling right now?
