I love math. Math proves the theorems about sciences such as physics and helps solve difficult problems. I envision problems in mathematical terms, and like to talk about it until I fall asleep. I love learning about math, because it is intuitive and forms the basis for many of my favorite sciences.
I jumped ahead of the school curriculum, and spent much of the summer with my dad and learned about applications of calculus.

RC Low-pass Filter
Low-pass filters remove high frequency components from a signal. A single-pole passive RC filter consists of a resistor and capacitor in series. «read more»
RLC Low-pass Filter
Filters can remove low and/or high frequencies from an electronic signal. They can be used to suppress unwanted frequencies such as background noise. This article shows the math and visualizes the poles in the
s-place, examines and visualizes the the step and frequency response. «read more»
RLC circuits are resonant circuits, as the energy in the system “resonates” between the inductor and capacitor. We will examine the properties of a resonator consisting of series circuit of an inductor (L), capacitor
(C) and resistor (R), where the output is taken across the resistor. «read more»
This is a zoomable Mandelbrot sequence using Node JS. Zoom in on an interesting area by dragging your cursor and go back to the previous view by pressing the “space” key. The program uses imaginary numbers to generate the sequence. These numbers have separate real and imaginary pieces. The different coordinates in the Mandelbrot set must pass a test. The set is white and the rest is another color.
My code for this project is at github.com or at khanacademy.org.
