Ultracoffee

How does one make ultracoffee?

With ultrafilters.

After all, it is said^{[by whom? Erdős or Rényi?]} that, "A mathematician is a device for turning coffee into theorems."

Note also that the dual of the coffee -> theorem -> corollary sequence is more economical:

Rollary -> cotheorem -> ffee.

The ultraversion of this argument cannot be posted due to WP:OR. Tkuvho (talk) 05:59, 7 March 2011 (UTC)
