# Jekyll article syntax

##### Abstract

This project is called jekyll-latex. It allows you to write markdown posts using the Jekyll framework with the beautiful typography of LaTeX and the MathJax library so you can render gorgeous equations like this one below: $$J(\theta) =\frac{1}{2m} [\sum^m_{i=1}(h_\theta(x^{(i)}) - y^{(i)})2 + \lambda\sum^n_{j=1}\theta^2_j$$

# Theorems, Definitions, and Proofs

The real numbers $\mathbb{R}$ are uncountable
If $\mathbb{R}$ is countable, then [0, 1] is countable as well. Hence there exists a map C from $\mathbb{N}$ onto [0, 1] with $$C(n)=\sum_{i=1}^{\infty} c_{i}(n) 10^{-i}$$ where $c_{i}(n) \in\{0,1, \ldots, 9\},$ are the digits in decimal expansion. Now consider a real number $$x=\sum_{i=1}^{\infty} \bar{c}_{i} 10^{-i} \in[0,1]$$ with $\bar{c}_{i} \neq c_{i}(i)$. Obviously $C(n) \neq x$ for all $n \in \mathbb{N} .$ Hence $C$ is not onto. A contradiction.
