MathML is a markup language used to describe mathematics as a basis for machine to machine communication. It provides a much needed foundation for the inclusion of mathematical expressions in Web pages.
MathML is very interesting for scientific web documents and what I found more interesting is that Firefox support MathML by default without any additional extension or plugin. For example Cauchy-Schwarz Inequality :
(
∑
k
=
1
n
a
k
b
k
)
2
≤
(
∑
k
=
1
n
a
k
2
)
(
∑
k
=
1
n
b
k
2
)
The source of the previous example is :
(
∑
k
=
1
n
a
k
b
k
)
2
≤
(
∑
k
=
1
n
a
k
2
)
(
∑
k
=
1
n
b
k
2
)
