 ## About Me
 
-The world of quantum mechanics is often depicted as a bizarre and counterintuitive place. Particles existing in multiple states simultaneously (\\|\psi\rangle = \alpha|0\rangle + \beta|1\rangle\\), spooky action at a distance – it all sounds like science fiction. But here’s the thing: quantum mechanics isn’t some fringe theory. It’s the undeniably successful framework that underpins the behavior of the universe at its most fundamental level.

 My passion lies in demystifying this "weirdness" and translating it into powerful, real-world applications. I believe that by embracing concepts like **superposition**, **wave-particle duality**, and **entanglement**, we can unlock a new era of technological innovation. My work focuses on the intersection of quantum computing and artificial intelligence, exploring how quantum algorithms can solve problems currently intractable for even the most powerful classical supercomputers.

-This is a description of a teaching experience. You can use markdown like any other post.
+Great observation, Raye — this is a **common gotcha** when working with LaTeX math in Markdown across different GitHub environments.

+
+## ✅ TL;DR: Why it works in GitHub *preview* but not on GitHub Pages (`github.io`)
+
+GitHub supports `$$...$$` and `\(...\)` inline in its **repository Markdown preview** (like in `README.md`) using built-in rendering.
+
+But **GitHub Pages (`username.github.io`) does *not* support LaTeX math out of the box**. You need to **enable MathJax manually** in your Jekyll-based site.
+
+---
+
+## ✅ How to Fix It on `github.io` (Enable MathJax)
+
+To render LaTeX properly on GitHub Pages, follow these steps:
+
+---
+
+### 🔧 1. Add MathJax to your `_config.yml` (if using Jekyll)
+
+```yaml
+markdown: kramdown
+kramdown:
+  math_engine: mathjax
+  input: GFM
+```
+
+---
+
+### 🔧 2. Insert MathJax script into your HTML layout
+
+In your main layout (e.g., `_layouts/default.html`), add this in `<head>` or before the closing `</body>` tag:
+
+```html
+<script type="text/javascript" async
+  src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js">
+</script>
+```
+
+If you're using **a static `README.md`** for a GitHub Pages home page (without Jekyll), insert this manually at the bottom of your Markdown:
+
+```html
+<script type="text/javascript" async
+  src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js">
+</script>
+```

+
+### ✅ 3. Then, use `$$ ... $$` for block equations:
+
+
+$$
+|\psi\rangle = \alpha |0\rangle + \beta |1\rangle
+$$
+
+
+Or inline math with `\( ... \)`:
+
+
+This is a quantum state: \( |\psi\rangle = \alpha |0\rangle + \beta |1\rangle \)
+
+
+---
+
+### Example Live Usage (Markdown with MathJax):
+
+
+## Quantum State
+
+$$
+|\psi\rangle = \alpha |0\rangle + \beta |1\rangle
+$$
+
+> In this expression, \(\alpha\) and \(\beta\) are complex amplitudes such that \(|\alpha|^2 + |\beta|^2 = 1\).
