Albrecht Dürer, Adam and Eve

Met curator Freyda Spira on advertising in **Albrecht Dürer’s Adam and Eve**, 1504.

Throughout his life, Dürer was in thrall to the idea that the perfect human form corresponded to a system of proportion and measurements and could be generated by using such a system. Near the end of his life, he wrote several books codifying his theories, including the Underweysung der Messung (Manual of measurement), published in 1525, and Vier Bücher von menschlichen Proportion (Four books of human proportion), published in 1528 just after his death. Dürer's fascination with ideal form is manifest in Adam and Eve. The first man and woman are shown in nearly symmetrical idealized poses: each with the weight on one leg, the other leg bent, and each with one arm angled slightly upward from the elbow and somewhat away from the body. The figure of Adam is reminiscent of the Hellenistic Apollo Belvedere, excavated in Italy late in the fifteenth century. The first engravings of the sculpture were not made until well after 1504, but Dürer must have seen a drawing of it. Dürer was a complete master of engraving by 1504: human and snake skin, animal fur, and tree bark and leaves are rendered distinctively. The branch Adam holds is of the mountain ash, the Tree of Life, while the fig, of which Eve has broken off a branch, is from the forbidden Tree of Knowledge. Four of the animals represent the medieval idea of the four temperaments: the cat is choleric, the rabbit sanguine, the ox phlegmatic, and the elk melancholic.

2. *Find the original function given the antiderivative:* The student is asked to find the original function given the original than apply it to find the value at a certain point on the original function.

1. *Find the particular member of the antiderivative family that passes through a certain point:* The student is asked to find the antiderivative of the original function and then solve for the constant given the point.

## Strategies

Knowledge of derivative and integral concepts is encouraged to ensure success on this exercise.

1. The antiderivative of acceleration is velocity, and the antiderivative of velocity is position.
2. Find the antiderivative of the function, then solve for the constant using the given point.

Arrays of Objects

**Arrays of Objects** is a talk-through in which Pamela demonstrates how to store arrays of Objects.

She starts out with a program previously used in the Variables section, which defines a function to draw Winston (called, appropriately enough, drawWinston...), and then includes four separate calls to that function, each with a different `x` and `y` parameter. She then demonstrates how, instead, two arrays could be used to store the corresponding `x` and y positions, and looped through.

She goes on to explain that there's an easier way though.  A single array can be created, including within it multiple objects, each of which stores one set of `x` and `y` coordinates.  By then looping through those objects, the same drawing can be created with just that one array:

```
var positions = [
  {x: 99, y: 117},
  {x: 294, y: 117},
  {x: 101, y: 316},
  {x: 294, y: 316}
];
for (var i = 0; i < positions.length; i++) {
    drawWinston(positions[i].x, positions[i].y);
}

```

Finally, she demonstrates that the drawWinston function can actually be modified to expect an object as input, rather than requiring the individual `x` and `y` values:

```
var drawWinston = function(facePosition) {
    var faceX = facePosition.x;
    var faceY = facePosition.y;

// which can then be called by:

for (var i = 0; i < positions.length; i++) {
    drawWinston(positions[i]);
}

```

Michelangelo, Studies for the Libyan Sibyl (recto); Studies for the Libyan Sibyl and a small Sketch for a Seated Figure (verso)

Met curator Carmen Bambach on the presence of genius in **Michelangelo Buonarroti’s Studies for the Libyan Sibyl (recto); Studies for the Libyan Sibyl and a small Sketch for a Seated Figure (verso),  c. 1510–11**.

This is the most magnificent drawing by Michelangelo in the United States. A male studio assistant posed for the anatomical study, which was preparatory for the Libyan Sibyl, one of the female seers frescoed on the ceiling of the Sistine Chapel (Vatican Palace) in 1508-12. In the fresco, the figure is clothed except for her powerful shoulders and arms, and has an elaborately braided coiffure. Michelangelo used the present sheet to explore the elements that were crucial in the elegant resolution of the figure's pose, especially the counterpoint twist of shoulders and hips and the manner of weight-bearing on her toe. Recent research shows that this sheet of studies was owned by the Buonarroti family soon after Michelangelo's death. The "no. 21" inscribed on the verso of the sheet (at lower center) fits precisely into a numerical sequence found on many other drawings by the artist that have this early Buonarroti family provenance.

Kirchhoff's laws

***Kirchhoff's laws*** is an article in the Circuit Analysis category/DC Circuit Analysis sub-category of Khan Academy's Electrical Engineering course.

Kirchhoff's Laws for current and voltage lie at the heart of circuit analysis. With these two laws, plus the equations for individual components (resistor, capacitor, inductor), we have the basic tool set we need to start analyzing circuits.

Movie Reviews-Challenge

**Challenge: Movie Reviews** is a challenge in the Objects section of Khan Academy's Intro to JS section. This challenge practices using arrays of objects. There are three steps worth 2100 points.

## Steps

There are three steps in this challenge:

1. *Display the Review* - The user is first asked to modify the program so that it displays the review for a movie in smaller text below the movie title.  The initial provided array contains one movie title and one review.
2. *Add a second movie* - The user is now asked to add a second movie (title and review) to the array.
3. *Display them all* - Finally, the user is asked to display the two movie titles in the array, with the review for each again appearing below the title in smaller text.

## Hints

1. Most of the skills necessary for this challenge can be reviewed by re-watching the "Arrays of Objects" talk-through if needed.

Our History

When our founder, Vanilla Dazzle joined Khan Academy the second time in the summer of 2014, she found that her friends thought she was silly for being on Khan Academy. She really wanted to share her online learning experiences with others, but Khan Academy isn't really set up for that sort of social learning interaction, especially since she was not doing coding yet. She met a few people over comments on Khan, but nothing substantial.

In the fall of 2015, she started doing the coding tutorials on Khan and now she wanted to have people to whom to show her programs. It had to people that programmed too. After all, if you showed a program to a regular person, they might not understand how much work went into your creation.They would think it was as easy creating that picture in MS Paint or something. On October 31st of 2015, she joined the Khan Academy wiki and started to chat on their chat room. This was nice. She could show others her programs and ask them questions and sometimes even help a new programmer.

However, she found that site to have various issues with which she wasn't happy. Additionally, she started to notice that a lot of the people programming on Khan Academy were also using Scratch. She signed up for Scratch. Eventually, she was thinking there should be a wiki that covers all online learning-especially these two popular sites. She had met HD Master in Central who is on Scratch, but not KA. He had helped her a few times and really knew his way around wiki.

KAOS was founded in the wee hours of the morning on the over night between February 4th and 5th which was a Thursday to Friday. Vanilla Dazzle asked HD and another online friend to be her admins. She some friends from the KA wiki to come work on this new wiki with her.
YouTube

YouTube, though not thought much as a learning site, is also a rich source of free educational content. This vast resource includes copies of the Khan Academy videos, as well as many videos about many subjects from various high school teachers, college professors, tutors and students looking to share their knowledge with others.

This above is an example of a user made programming tutorial that can be found on YouTube.

## Noted Educational YouTubers

* Khan Academy
	+ Numerous topics
* Math by Fives
	+ Math for college level
* Pajholden
	+ Economics videos
* Yaymath
	+ Math for HS level some college math
Vanilla Dazzle

Vanilla Dazzle is more into the artistic aspect of coding. She has made avatars for wiki users: Blaze Programming, Bohanyao, Nick, Anthony Jacquez and herself. She has helped some more pick out avatars from image searches online. Her most recent online learning activities are working with Paint.net and various sites for basic coding.

In addition to coding and graphics, she became interested in foreign languages before she even started kindergarten and now practices on Duolingo.

## Programming Languages

* CSS
* HTML
* Processing JavaScript

## Khan Academy Highlights

In January of 2016, her "Sunset with Lake" skyrocketed to the top of the hot list. She always likes to say that she is an artist who programs more than a programmer. She calls it "art by coding."

* Can be found on on Khan Academy here

* Has 3 programs with over 100 votes
* Attained 659 day streak before site refused activity
* Has over 10 million points, holding Tesla
* Has 59 Sun badges.
* Has watched over 7.4k videos

## Duolingo Highlights

* Found here
* On levels 4 and 8 for the two languages she's reviewing
* On levels 2 and 4 for the two new languages
* Has over 2,900 XP

## Scratch Highlights

* Is a scratcher
* Curates Team Khan Academy
* Has 3 shared projects
* Has 15 followers

## Wikia Highlights

She is an active presence. She is the founder of this wiki–KAOS. Across all of Wikia, she has over 7,500 edits on over 70 different wikis. She is admin on a handful of wikis. Recently, she did the wallpaper and ico for the Portuguese Duolingo site, fancrosoft, a Microsoft fan site and Power Master, a site devoted to the game series.

## Alt Account Controversy

In early 2016, there was a controversy that she was using other accounts with malicious intent on Wikia. The truth is that she wanted to be able to talk to some people without being bothered by others, as some users would attack her when she entered a chat room. Currently, she is using Vanilladazzle and DazzleVanilla to chat, My Chat Logger to watch the chat room when she isn't there.

She often uses alts with two computers, such as one to see if messages come in chat and the other to switch tabs and chat when people are in the chat room. She also uses two accounts to send a link from one computer to another when one is running sluggish and filling up with links. She also uses multiple accounts because private messaging goes down a lot and as admin, she needs to private message others, such as her admin or chat mod when there's a troll in the chat room.
Vocabulary dot com

**Vocabulary.com** is another online learning site which aims to enhance the user's vocabulary. It uses points as an incentive for more learning. The user gets 0-100 points for each question answered correctly, which they must do this within three tries. As one tries to master as many words as possible, (s)he levels up and gets more badges.

Vocabulary.com also has the fastest searching dictionary on the internet. It is recommended for everyone to try it out and see!
What is programming?

**What is programming?** is the first Intro to JS course on Khan Academy. The video is laid out on YouTube embedded on the Khan Academy site, a contrast from most of the course which is laid out in "coding talk throughs." Pamela gives the viewer a basic idea of what programming is capable of. She likens a computer to a very obedient dog. Finally, she entices the viewer to continue on and learn to write programs of their own.

Snap!

**Snap!** looks just like Scratch. .. What? This is because Snap! was developed out of Scratch 1.4.

While Scratch is on MIT's website, Snap! is on Berkley's.

With Snap!, just like with Scratch, the user programs the computer with plain English blocks that snap together.

Snap adds new blocks such as warp, which will do things all at once.
