The topology of the syntonic temperament's tonnetz is generally cylindrical. Any syntonic "equal" tuning (i.e., a tempered width of the perfect fifth which divides the octave into a number of equally-wide intervals) snaps this cylinder into a torus(the shape of a ring doughnut, a hula hoop or an inflated tire), showing that it has a topology equivalent to S1×S1.

WTFormality.
Much philosophy of logic is shaped, explicitly or implicitly, by the thought that logic is distinctively formal and abstracts from material content. The distinction between formal and material does not appear to coincide with the more familiar contrasts between a priori and empirical, necessary and contingent, analytic and synthetic—indeed, it is often invoked to explain these. Nor, it turns out, can it be explained by appeal to schematic inference patterns, syntactic rules, or grammar. What does it mean, then, to say that logic is distinctively formal?
Keep Breathing and check Inbox.
I've just opened my email and there's nothing out of the ordinary there. It's the usual daily flood of schedule, project, travel, information, and junk mail. Then I notice...I'm holding my breath.
As the email spills onto my screen, as my mind races with thoughts of what I'll answer first, what can wait, who I should call, what should have been done two days ago; I've stopped the steady breathing I was doing only moments earlier in a morning meditation and now, I'm holding my breath.
And here's the deal. You're probably holding your breath, too.
