Question

How can I indent the paragraphs which follow a heading?

I want to ask why "Hello!" doesn't indent.

% work1.tex
\documentclass{article}
\begin{document}
   \section{Introduction}

   Hello!

   Hi

\end{document}

the section in article class is defined so, that the paragraph after it is not indented
Welcome to TeX.SE. The point of indenting a paragraph is to make it obvious that this is the start of a new paragraph. After a \section it is obvious that it is the start of a new paragraph so no indent is added.

That's a common rule for indent in some languages: it's indent only the second and other paragraph.

If you want indent first paragraph too: \usepackage{indentfirst}.
