    * **Gaussian Distribution Formula:**
 
-     $\huge \color{DeepSkyBlue} f(x) = \frac{1}{\sqrt{2\pi\sigma^2}} e^{-\frac{(x-\mu)^2}{2\sigma^2}}$  
+     $\huge \color{DeepSkyBlue} f(x) = \frac{1}{\sqrt{2\pi\sigma^2}} e^{-\frac{(x-\mu)^2}{2\sigma^2}}$

+      Where:  
+     - **\( \mu \)**: Mean of the distribution.  
+     - **\( \sigma \)**: Standard deviation.  
+     - **\( x \)**: Random variable.  
+
+     This formula is widely used to model measurement uncertainties in quantum mechanics.
