and this is L24_CAT
it's dodeca and not ... ......tetracosa bc i didn't know tetracosa was a prefix (that's actually pretty awesome i might use it) (source)
and there was a thing with the number 2
they exist bc i needed a character for my first Java project. L1 was created in like 60 seconds in MS Paint. that is the real actual first ever image of him and it is that small and crusty. i love him dearly.
JOptionPane(...);s ...
L1 and L24's names stand for
Laptop 1 and Laptop 24
(my assigned machines for year 1 and year 2 Programming)
i like to draw them being buddies and lookin cool and defying reality
(get it because i hadn't taken Physics yet)
propagation of a wave ☆ﾟ.*･｡ﾟ(November 10th, 2022)
we were learning more about waves in physics and i loved this example so much i had to sketch it
(my professor brought out a whole big gadget to show us!! a transverse wave (the standard wiggly one) going down a line of sticks connected by string 0w0 ) and,
this one has a sequel! :D ☆ﾟ.*･｡ﾟ(March 20th, 2024)

see, 24, this is an oscillation (L1 is scraping his tail against a whiteboard).
up, down, up, down, up down up down up down (the negative space is full of repeated up, downs)
BUT, we're far from done yet...
it's just sitting there!!!
where is it going?
right now, just up and down...
to make a WAVE,
the oscillation must move through space!
the basis waves are formed by 1 "oscillator" & 1 "perpendicular direction of travel"
(a diagram shows the ups and downs spreading out across a line to form wavey ups and downs).
the area or material where the wave is moving through is called its "medium."
note: math provides more precise descriptions of specific waves
(another diagram plots out the differences between a sine and a cosine wave at key points! it also provides several equations for plotting custom waves, such as
y = Acos(x-h)+k,
where A is the amplitude of the wave (how high it crests above 0), h is how displaced it is along the x axis, and k is how displaced it is along the y axis).
(note from the future: i forgot about B! wave equations have a special way to make them... tighter or looser, scrunched or pulled apart, called period. with y = Acos(B(x-h))+k, you can control this part too (often used to take the wave off of the 2π scale))
(a final diagram is the same as the first image: a 3D perspective showing the plane of the wave, oscillation on the plane, and the direction of propagation, through the medium, perpendicular to the wave)
