This week is TECHNICALLY the start of SelfDesign, so I started getting ready ๐Ÿ˜€ I started doing my learner slideshow, which is a presentation about what your goals are this school year, and how you improved in the summer, so I wrote about… coding + math + science ๐Ÿ˜ Other than that, I did a few questions on Khan Academy multivariable calc about gradients, and I started learning about special relativity!

I did some questions about gradients, which are basically vector fields in 3D that point the way up a hill. Basically. If you have a 3D graph, the gradient of the graph will show how to increase your altitude the fastest.
Here is the graph of f(x, y) = (-x^2)-(y^2). As you
can see, all the gradient arrows point toward the origin, meaning to go up this hill the fastest, walk toward
the origin in this graph.
This is an online software I’m using to draw this called math3d, by the way. Find the file for this project here: Here is another one!

I started doing special relativity. I didn’t really get it so I’m gonna try to understand it again tomorrow (Tuesday).


Today was the meet and greet for grade 6-9 learners on Selfdesign, so I did that! Basically, five SelfDesign coordinators met with everybody in grades 6-9 on a Zoom meeting and talked about what they do. All of the activities might be fun (such as the gr. 8-9 circle where there is a theme every month, and we talk about things related to the theme), but my favourite out of them all (besides the Minecraft server of course) was the Genius hour because what you do is basically go on a zoom meeting for an hour and talk about what you’ve been working on, and then everybody else giving you tips it’s the BEST! Other than that, I learned about reflection, refraction, and Snell’s law, and I worked out a question about distance and refractions in the water! I also finished learning about Gradients and I got 100% on the quiz ๐Ÿ˜€ and I also learned about vector-valued functions and how you can take the derivative of a position to get velocity.

I did the problems about gradients AGAIN, and I got 100% so I get them now!
I started learning about vector-valued functions and how they relate to velocity and acceleration and forces.
I started learning about reflection and refraction and Snell’s law, which is a law about refraction.
I did a problem with Snell’s law on my notebook, and got the answer right ๐Ÿ˜€


Today was the day that I started writing about something, and that something was about a tiny asteroid called Queta that was discovered around a Trojan asteroid called Eurybates. I also learned about lenses and made a nice colour drawing of the derivation of the thin lens equation.

I saw this cool video about discovering a new satellite around a Trojan asteroid (called Eurybates) and it looked cool, so…
… I learned more about Trojan asteroids and what they are (they’re basically asteroids that orbit in front and behind a massive planet), and how a mission called Lucy will visit 9 asteroids that are in front and behind Jupiter, which has the most Trojan asteroids. This looked fun, so…
I started writing about it!
I did the questions on divergence and FINALLY got 100% ๐Ÿ˜€
I learned about lenses and how they work, and I also…
Derived the thin lens equation from triangles! The thin lens equation is a way to relate the distance to the lens and the image distance to the lens.


Tomorrow is my birthday ๐Ÿ™‚ But other than that, I wrote an article (AGAIN) about brown dwarves and an accident that lead to believing that there are more brown dwarves in the Milky Way. I also did math (about approximating 3D curves with a quadratic, kinda related to the Taylor series) and science (about circuit components).

I started learning about circuit elements, such as resistors, capacitors, inductors, batteries, all the good stuff.
I started learning about how you can approximate a 3D curve with a quadratic equation that has both x and y in it (a 3D parabola).
Here is a 3D parabola in a really good graphing software called Math3D! Find the project here:
There was a discovery of a brown dwarf that suggests that there are more brown dwarfs than previously thought…
So I wrote about it! Find the article here:
I added a piranha plant that comes out of the pipes in my Mario scrolling platformer game!


Today is my birthday! Woke up to a sign that says โ€œHAPPY BIRTHDAY!!!โ€ And opened presents, which were books and more books. Later in the day came a pack of dominoes! I wanted those, so yay! ๐Ÿ™‚ I also had an online party with my friends from my book club that I used to run, and so we played online games like and UNO online. Not only that, but I also studied, lol. For some reason, I don’t have those photos, sooooโ€ฆ


Iโ€ฆ coded. And I did my SelfDesign learner slideshow, where you talk about what you like and stuff. I also invited one of my friends over at 2:00 pm, and we hung out together!

I created logic gates out of dominoes! This one is an AND gate because the output (bottom left) will only trigger if both inputs are pushed over!
This one is an XOR gate because the output (bottom) will only trigger if one or the other, but NOT both are triggered. I found this in the โ€œThings to Make And Do In The Fourth Dimensionโ€ by Matt Parker.
I added two new particles to my sand simulation! Gas and mud.
I started trying to make a 3D engine with clones!
