Math Demonstration

(TBD) Demonstrates how to use math --- courtesy of [$ K^AT_EX $] --- in the brutalist-minimalist style.

In the meantime mathemtical formulas are properly transscribed if the
summary is take from the first [$ N $] words of an article, but
and explicit summary is any way recommended. Let's have some math:
[$ \psi^2 > \alpha_0 $].

This is a second paragraph, just to see how that comes out. Aliquam
erat volutpat.  Nunc eleifend leo vitae magna.  In id erat non orci
commodo lobortis.  Proin neque massa, cursus ut, gravida ut, lobortis
eget, lacus.  Sed diam.  Praesent fermentum tempor tellus.  Nullam
tempus.



### Consectetuer adipiscing elit.

Dolor sit amet, consectetuer adipiscing elit.  Donec hendrerit tempor
tellus.  Donec pretium posuere tellus. [$ \psi^2 > a^2 $]. Proin quam
nisl, tincidunt et -- [$ a < b $] -- mattis eget, convallis nec,
purus: [$ \psi^2 > a^2 $].

Should not render as math: We write a formula like *[$* \psi *$]*.

Now a math display:

[$$   \psi^2 > a^2a   \newline
      asdasdas \\\\
	  asdsd
$$]

Frankly. the source is a bit ugly, b/c we cannot have an empty line in
the source (this is different from TeX).

[$$
  \frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} \equiv 1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}} {1+\frac{e^{-8\pi}} {1+\cdots} } } }
$$]
[$$
  \left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)
$$]
