[Tex/LaTex] How to center the title and the authors

Question

I have two questions.

1. How can I center the the title rather that its natural position?

2. How can I remove the date?

Here is the code:

\documentclass[12pt,a4paper]{article}
\usepackage[latin1]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}

\title{ \begin{huge}
\textbf{Geometry of manifolds and differential forms} 
\end{huge} }

\begin{document}

\maketitle

\end{document} 

Here is the output:

Answer 1

This would do:

\documentclass[12pt,a4paper]{article}

\begin{document}

    \begin{titlepage}
    \centering
    \vspace*{\fill}

    \vspace*{0.5cm}

    \huge\bfseries
    Geometry of manifolds and differential forms

    \vspace*{0.5cm}

    \large Obi Wan Kenobi

    \vspace*{\fill}
    \end{titlepage}

\end{document}
