Analogy: vectors as colours

  Colours can be encoded as a list of values [R, G, B], and we can conceptualize this as a more abstract type of vector. 

"Red", "green", and "blue" behave as our basis vectors from which we can construct all other colours by combining them in varying ratios. 

We can also have different basis sets such as the CMYK system. {C, M, Y} forms the basis set.

I'm sure there's already an analysis on this in computer graphics!

Molar Enthalpies

remember all those pesky chemical equations and how to balance them out?  let's take a look at how they're used in thermochemistry! hot 1 H₂(g) + ½ O ₂ (g)  →  1 H ₂O(g) + 241.8 kJ this is an example of a "thermochemical equation"! it's a little different from what u might be used to for 2 reasons: what is this "241.8" kJ nonsense!?! that's not any chemical I recognize! there's a fractional term (½)!! what's up with that!?!? addressing the "241.8 kJ":  this is a measure of the enthalpy change  ( ΔH) , or the change in the system's total energy  that happened during the reaction!  remember that chemical reactions always involve the making and breaking of bonds - this requires a change in the system's energy. for our purposes, energy change will always be measured in joules or kilojoules (1000 J = 1 kJ)! the fact that the ΔH is listed on the "products" side of the equation means that th...

Mapo tofu recipe

Image
Here's my recipe for Korean-style mapo tofu. It's inspired by Maangchi , Korean Bapsang's , and Just One Cookbook 's recipes. You can use soft, medium, or firm tofu. I bloom the garlic, ginger, and gochujang in oil at the beginning to aim for the feeling of using chili oil. Since these ingredients burn easily, I start with them in a cold pan and then increase the heat while stirring to avoid scorching them. Be warned that the gochugaru might make you sneeze as it blooms. Ingredients: Main ingredients - 1 package of tofu, cut into 1-inch cubes (454 g) - 1/2 package (?) of ground pork or ground beef (227 g) - 6 to 8 green onions (cut into 1-inch long pieces) - 1 onion (cut into chunks, 1 cup) - 1 + 1/4 cups stock (chicken, beef, etc.) — I mix 1 tsp of Knorr chicken broth mix into 1.25 cups of water (1 cup will go into the main dish, the remaining 1/4 cup will be mixed with corn starch to form a slurry to thicken the final dish) - 1 Tbsp gochugaru - 1 Tbsp c...

~Fixing Up Korra's Face~

Image
So probably almost everyone who has watched The Legend of Korra knows about the Pierrot incident. If you don't, here's a quick rundown of what happened: Bryan and Mike didn't originally know that there was going to be more than one season of Korra, so Studio Mir (the animation studio for Korra) only signed a contract for one season of the show. When they got an offer to animate Book 2, they also got another offer from Sony Pictures to animate a show called "The Boondocks." Since the animation process of Korra was so... (How do I word this? Crazy? I'll just use "crazy.") [EDIT: I think the word I was looking for was "tiring".] Since the animation process of Korra was so tiring, they chose to animate Boondocks instead, and Pierrot filled in with animating Korra. Although Pierrot got the job done, there were some... minor issues.  Now that that's out of the way, let's move on to the reason I posted this in the first place. I decide...
