"Fit the sound and vision to the pattern of his brainwaves..."

In reality, of course, there is no clear difference between a "pitch" and a "rhythm"; both are subspecies of periodic phenomena related to the physical oscillation of air molecules, electric currents, or other media. In practice the distinction is somewhat provisional and is in principal a perceptual or psychoacoustic effect as opposed to a material property.

By definition a transient must spend at least some of its finite period in the "on" part of the cycle, meaning there can be no such thing as an ideal transient (also known as an ideal pulse), which would have zero duration and thus be infinitely thin. Such transients, although conceivable, would likely escape detection by anyone, and are therefore seldom encountered. 

Pitch and rhythm are ultimately just descriptions applied to collections of detectable transients that are variously interepreted by brains as being components of (re)cognizeable harmonic or rhythmic structures. The rate of oscillation, along with other cues like harmonic content, determines the mode of interpretation, so that a pitch or frequency is equally a very fast rhythm, and a rhythm is also like a kind of extremely low-frequency pitch or melody.

Blinken lied to Congress about Israel

As we might have expected, Secretary of State Antony Blinken suppressed the findings of two internal reports confirming what was already patently obvious to almost anyone paying attention: Israel deliberately blocked aid shipments to the beleaguered Palestinians trapped in Gaza. Meanwhile, no significant pressure has, to anyone's knowledge, been exerted on the Israeli government to curtail their ongoing genocidal campaign to exterminate the Palestinian population under the pretext of "national security"; apparently Israel's reinvigorated efforts to escalate other conflicts in the Middle East have upstaged their peril. The general consensus being that the wider world, composed as it is of various nations, is in fact significantly less secure than it was at the outset of these machinations, the disconnect between rhetoric and reality on the part of the leaders of the "free world" has scarcely been so stark. 

If the task of defending democratic freedoms must now include, in addition to an illegal 57-year occupation followed by innumerable other breaches of international law during that period, inventing endless excuses for mass murder alongside an unprecedented attack on free speech intended to marginalize, discredit, criminalize and ultimately silence all critics, then like Orwell we must finally conclude that the corruption of language is indeed central to the consolidation and maintenance of the power structure. 

This time, however, we need not imagine the "boot stamping on a human face -- forever." It's here already: it's on every channel, and it wants your campaign donation.    

Spring reverb project taking shape

Here's a peek at the workbench, which is actually supposed to be my dining room table! The mini reverb tanks - one for each channel, as this is going to be a stereo unit - are visible in the extreme upper right:

 

I'm basing the drive and recovery amplifier designs on some extremely helpful suggestions from Elliott Sound Products, whose online project archive is a fantastic internet resource for DIY audio experimenters. Both are simple op-amp circuits with a minimum of external components, so I'm hoping to get a functioning prototype circuit up and running soon.

 

Indiana Dunes sequel

There are many more Dunes Park pics. Sorry, I ran out of time last time to upload them.

 

 

 

 

 

 

 

 

 

 

 

Great expectations

Countless examples of mathematics abound in nature, but there is yet reason to doubt that nature, taken as a whole, is at its root a sub-branch of mathematics.

Don't miss it!!
