If you’re dealing with a lot of files and get messages like:
mv *.* tmp/
-bash: /bin/mv: Argument list too long
then you need xargs.
xargs is a command of the Unix and most Unix-like operating systems. It becomes useful when you want to pass a large amount of arguments to a command. In that case xargs will break the list of arguments in sublists large enough to be acceptable.

Hardly a mathematical statement but it can be a useful shortcut to explaining why an argument isn’t well-structured…
From ScepticWiki:
The claim “you can’t prove a negative” is often used as a shorthand in discussions to refer to the difficulty of gathering experimental evidence to “prove” that something does not exist. Proving that a phenomenon isn’t real takes a lot more time and effort than it takes to demonstrate it. This is especially true when the definition of the phenomenon can be changed at will by its believers.
In criminal law, the maxim of “You can’t prove a negative” is reflected in the “presumption of innocence”. That is, arguments of the form
are inadmissible.
Since it is perfectly possible to not-commit a crime and at the same time, have no evidence of that non-commission, the lack of proof does not imply anything.
Often, of course, one can prove that a defendant didn’t commit a crime, which again demonstrates that “You can’t prove a negative” is of limited value.
It has been claimed that the United Nations demanded that Saddam Hussein prove the non-existence of weapons of mass-destruction under his control. This may be historically inaccurate, but had such a demand been made, it would have required evidence that every square inch of Iraq did not contain WMD.

They solved the problems of a 535m runway and the altitude of the control tower at 6581 foot by just making it slope so you land uphill and take-off downhill - neat!
