Sunday surprise, my ashes when the time comes

Monday, August 14th, 2017

[ by Charles Cameron — the poem as guided tour ]
.

So, my son Emlyn asked me where I would like my ashes scattered when I’m gone, offering to do me that service, and the ensuing discussion made it clear I had an opportunity not only to send him to some places I’ve loved where he’d be likely to find adventure, but also to provide him with reading (or listening) along the way — again, close to my mind and heart and potentially revelatory for his.

^^

I was tossing this around in my mind a day or two ago, and this poem announced itself:

Paradise or Pasadena, since you asked

I should like my ashes scattered in the upper atmosphere,
in Bach to be precise,
in deep feeling, in the St Anne Prelude and Fugue,
in “not of this world” in other words,
believing that if met by JSB
at the General Resurrection, I was most choicely planted.

Bach, seriously, is the mountain range I have assiduously
climbed since early youth,
and the St Anne not the most obvious,
but among the most glorious works therein,
though I am also vastly taken by Contrapunctus IX
and the Dorian Toccata was my first love.

More practically, fold me between pages of Yeats or Rilke,
and leave me on a bench in the Huntington Gardens.

That’s by no means my final response to Emlyn’s question, I look forward to many more hours of pondering and reminiscing. But it’s a thought..

Here, for your delight and enrichment, are the musical offerings the poem mentions:

The St Anne Prelude and Fugue, played here by Peter Hurford:

Contrapunctus IX from The Art of Fugue, played by Glenn Gould on piano, his usual instrument:

and, in a rare instance for Gould, on organ:

— and the Dorian Toccata and Fugue, my first Bach love, which I bought, treasured, and binge-listened to back in the late 50s (?) on a 45 rpm disc:

Noteworthy, the second of two images of Ton Koopman accompanying that last recording — which shows the fierce nature of Koopman when he was young — fading in right at the end of the Toccata:

Ton Koopman

I would love to have known him back when..

And place — the Huntington Gardens in Pasadena, which include a garden of flowers named in Shakespeare’s works, a Japanese garde, rose garden, and — my absolute favorite –the Desert Garden, containing 5,000 varieties of cactus and other xerophytes across 10 acres..

I suspect that losing oneself in those 10 acres is the closest thing to visiting an alien planet to be found on this one…

Once you’re in the garden and have escaped the lure of the cacti, the cool of the Huntington Library is nearby — with some stunning William Blake illuminations perhaps, and both a First Folio Shakespeare and the remarkable “bad” First Quarto of Hamlet which preceded it.

How has the mighty soliloquy been truncated:

To Die, to sleepe, is that all?

Cacti, roses, Folio, scholars, tea rooms — heaven, in its earthly approximation…

Polarized light — pls review before final exam, Thurs

Sunday, August 13th, 2017

[ by Charles Cameron — actually the exam is daily, ongoing — and we’re not scoring very high marks ]
.

Unpolarized light vibrates in any planes:

A light wave that is vibrating in more than one plane is referred to as unpolarized light. Light emitted by the sun, by a lamp in the classroom, or by a candle flame is unpolarized light. Such light waves are created by electric charges that vibrate in a variety of directions, thus creating an electromagnetic wave that vibrates in a variety of directions. This concept of unpolarized light is rather difficult to visualize. In general, it is helpful to picture unpolarized light as a wave that has an average of half its vibrations in a horizontal plane and half of its vibrations in a vertical plane.

Polarized light vibrates in only one plane:

It is possible to transform unpolarized light into polarized light. Polarized light waves are light waves in which the vibrations occur in a single plane. The process of transforming unpolarized light into polarized light is known as polarization.

The most common method of polarization involves the use of a Polaroid filter. Polaroid filters are made of a special material that is capable of blocking one of the two planes of vibration of an electromagnetic wave. .. In this sense, a Polaroid serves as a device that filters out one-half of the vibrations upon transmission of the light through the filter. When unpolarized light is transmitted through a Polaroid filter, it emerges with one-half the intensity and with vibrations in a single plane; it emerges as polarized light.

This works either way — so to speak, either vertically, or horizontally — though not, by definition, both at once. Ohh, and there’s paradox involved:

Read the whole lesson at The Physics Classroom: Polarization — and memorize, remember?

Ali Soufan notices polarization in our political sphere wrt events we label or do not label terrorist:

NPR likewise:

Tim Furnish sees this polarization as avoiding mention of Islamic influence when it is clearly present:

And then there’s this:

Sebastian Gorka told MSNBC

Gorka in full:

Sometimes an attack is unequivocally clear for what it is. When somebody shouts ALlahu Akbar as they’re stabbing a police officer, it’s pretty clear it’s not a case of the mafia robbing a bank, wouldn’t you say so?

Eh?

Vox is oppositely polarized to Gorka et alii:

As, indeed, am I.

Incientally, all you special ops types with cool shades:

For lightweight, functional shades that protect your eyes in any lighting situation, Oakley has designed the SI Flak Jacket. Featuring an innovative 8.75 base lens curvature for optimal peripheral vision, these sunglasses provide side eye protection as well as a maximal field of view. The stress-resistant O-Matter frame found in many Oakley tactical models is lightweight, ergonomic and will not succumb to the pressures of constant wear and travel. The Plutonite polycarbonate lenses fully filter out harmful UVA, UVB, UVC and blue light up to 400 nm for maximum sun protection. Oakley also has included an Iridium coating on the lenses which reduces glare in extremely bright light. For adaptability in any environment, the lenses are easily interchangeable. « less

Take heed:

Polarization has a wealth of other applications besides their use in glare-reducing sunglasses.

Like — in USian politics?

Okay, time for the test. Sample question:

Answer:

A. Referring to the above question, the glare is the result of a large concentration of light aligned parallel to the water surface. To block such plane-polarized light, a filter with a vertically aligned polarization axis must be used.

On the Intelligence of the Artificial, thus far

Here we are on the merry-go-round:

YouTube AI deletes war crimes evidence as ‘extremist material’

YouTube is facing criticism after a new artificial intelligence program monitoring “extremist” content began flagging and removing masses of videos and blocking channels that document war crimes in the Middle East.

Middle East Eye, the monitoring organisation Airwars and the open-source investigations site Bellingcat are among a number of sites that have had videos removed for breaching YouTube’s Community Guidelines.

The removals began days after Google, which owns YouTube, trumpeted the arrival of an artificial intelligence program that it said could spot and flag “extremist” videos without human involvement.

But since then vast tracts of footage, including evidence used in the Chelsea Manning court case and videos documenting the destruction of ancient artifacts by Islamic State, have been flagged as “extremist” and deleted from its archives.

Without human involvement?

Humans were involved in the decision to let this AI proceed in real time “without human involvement”.

H Sap or AI? — who’s to trust?

King Cnut rebukes N Carolina legislators, & Trump by extension

Saturday, August 12th, 2017

[ by Charles Cameron — a meditation on sea-level rise ]
.

A thousand years later, the lesson King Cnut sought to teach his nobles still hasn’t altogether sunk in.

The North Carolina story is from 2012, and I haven’t been tracking to see if there have been any changes since then — but the attitude behind the gutting of the EPA under President Trump is simply “more of the same”..

Humility is the key word in the article on King Cnut.

    .

    President Trump certainly spoke of visiting “fire and fury” on the DPNK as quoted by the Economist in its DeafCon page (upper panel):

    The question is whether the use of the phrase to headline a piece on the Alt-Right torchlight protest at UVa (lower panel) is appropriate or not?

  • Does it trivialize the serious matter of potential nuclear war by applying Trump’s phrase to a mere few hundred protesters,
  • or does it rightly intuit that the fury and fire of the Trump-Bannon platform — as applied to the DPNK nuclear program — is of the same cloth as the fury and fire of the protesters, and thus entirely applicable and appropriate?

    Metaphors, analogies, parallelisms, paradoxes — my stock in trade — are delicate matters, and should be treated with care.
