If we have never discovered sinusoids
Any repetition would be unnoticed,
Time would be linear,
History would be unnecessary.

But every now and then
Numbskulls attempt
To awake buried ghosts
As if memory would only serve
To revive the past
Rather than being
An instrument for learning.

**** you mathematicians
For exposing the ups and downs
Beyond any logic of continuity.

**** anyone who can look at it
And still not see the pattern.
