He also created an account on the library website, but couldn’t figure out how to create a new project. We should look at it together this week when I finally have more time.
These are two small videos of Simon trying the D3 library out:
This weekend Simon came back to his old fascination, Fractal Trees. This time he didn’t just follow along Daniel Shiffman’s coding challenges, but created customized versions of Daniel’s trees, adding color and physics in some cases or writing the code in object oriented manner:
This weekend Simon told me he came up with this rule that if you take two denominators that make rational fractions when you divide one by those denominators and you multiply them together, you always also get a denominator that makes a rational fraction:
I heard Simon jump and talk about Newton’s Laws at the same time, so I asked him to remind me what all the 3 Newton’s Laws were for the camera:
Simon built a program in Codea visualizing the absolute value of a vector:
We continue reading the Russian adventurous math books by Vladimir Levshin (1904-1984) – see an older post about it – and Simon is often excited about the challenges discussed. This time however, he first thought that something was impossible (and the Russian book said that, too), but our amazing favourite Murderous Math thought otherwise! It was one of the three oldest “unresolved” problems in the world, about how to double a cube (and let it remain a cube), which basically boils down to “how to draw the cube root of 2”:
Some more unrelated notes that Simon made recently, while listening to the Russian adventurous math book:
