Number
representation was the topic for week eleven, which basically focused on binary
numbers. At the beginning of the week, I did not feel comfortable with binary
digits, but through the week I, certainly, progressed with my understanding. As
humans, when counting we tend to group things in 10. However, computers do not
use decimal numbers, they use voltages, which is similar as use just two
fingers, instead of ten. In binary numbers, the only digits are one and zero,
and because we are so used to do operations in base ten numbers, it is
difficult doing operations with binaries. In fact, it took me a while to feel comfortable
doing sum or multiplication with binary, specifically addition. But thanks to
the practice fields that professor submitted, I mastered operations with
binaries. I realized that it was the same as doing operation with decimal
numbers, but just using zero and one, for instance, 1+0=1, 0+1=1. The only
difference is when adding one and one, which equals one and zero 1 + 1= 1 0. Overall,
binary numbers where complicated at the beginning, but they provide us with an
insight of what is going on inside of the computer.
Along with the concepts of colors, we started the animations topic. In fact, an image is not animated if does not change somehow. To change an image, we use the function repeated which takes 3 inputs: a function, an image and a number. However, this function produces a list of images, not exactly an animation. Thus, we started to work with the big-bang function. As its name suggests, big-bang function creates something, in this case an animation. Even though this new command allows us to create something different and unique, as an animation; I did not like it at first because I had trouble initially understanding what it is asking me to do. Specifically, I was confused on the use of freeze which is a function that basically delete all the previous information of the element, in this case animation. What happens is that you delete all the previous information of an animation. In other words, you cannot come back to the original image. I understood that after performing by myself di...
