General ⇒ creating definition using \theorem

[feanor_3]

Hi,
I would like to create definitions with the command \theorem or in another way, such that

\begin{theorem}[Speed]
This is a definition
\end{theorem}

looks like this:

Peed This is a definition

How can I do this?

If you really want to be able to change the name using the environment's optional argument, then you could e.g. copy the definition of the proof environment in the amsthm.sty file of the amsthm package into your preamble and adapt it.

Remember to add the required commands for the at-signs.
