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.

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.

    Enantiodromia — it’s when something turns into its opposite — “freedomof speech” and “freedom of religion” being arguably current examples. The term comes to us from Carl Jung, who got it from Heraclitus.

    Richard Avedon used solarization, the photo technique whereby blinding whites show up as black, in a colorized form in his celebrated images of John, Paul, George and Ringo.

    [ and what’s so excellent here from the point of view of my own personal predilections is that John is the most futuristic, George the most mystical, Ringo clearly the most human — and Paul a barely distinguishable blur of colors signifying very little ]

    Devotion, modeled in magnet and iron filings

    Friday, June 16th, 2017

    [ by Charles Cameron — science and Islam, but not the creationist, the analogivcal approach — sufism and the nature of pilgrimage ]
    .

    I am apparenrly not alone in finding that iron filing surrounding a magnet resemble pilgrims cirucumambulating the Kaaba:

    The upper photograph depicts the work of the artist Ahmed Mater. A note elsewhere on his work notes:

    Ahmed Mater is a Saudi artist and qualified GP. Working in photography, calligraphy, painting, installation and video, Mater reflects his experiences as a doctor and the ways this has challenged his traditional background and beliefs, and explores wider issues about Islamic culture in an era of globalisation. In the series Magnetism, what at first appear to be pilgrims circling the Ka’ba, the sacred building at the heart of the sanctuary at Mecca, are in fact iron filings spiralling around a cube-shaped magnet. Mater refers to the spiritual force that Muslim believers feel during Hajj, the pilgrimage to Mecca.

    **

    The lower photograph, portraying actual pilgrims circumambulating the Kaaba, is accompanied by the following tale of Junayd:

    A man came to visit Junaid Baghdadi, whose life reflected no change, even after having performed Hajj.

    Junaid asked him: “Where are you coming from?”

    “Sir, I have returned after performing Hajj of the House of Allah”, was the reply.

    “So, have you actually performed Hajj?”

    “Yes, Sir, I have performed Hajj “, said the man.

    “Did you pledge that you would give up sins when you left your home for Hajj?” asked Junaid.

    “No, Sir, I never thought of that”, said the man.

    “Then, in fact, you did not even step out for Hajj. While you were on the sacred journey and making halts at places during the nights, did you ever think of attaining nearness to Allah?”

    “Sir, I had no such idea.”

    “Then you did not at all travel to the Ka’bah, nor did ever visit it. When you put on the Ihram garments, and discarded your ordinary dress, did you make up your mind to abandon your evil ways and attitudes in life as well ?”

    “No, Sir, I had no idea of that.”

    “Then, you did not even don the Ihram garments!” said Junaid ruefully. Then he asked; “When you stood in the Plain of Arafat and were imploring Allah Almighty, did you have the feeling that you were standing in Divine Presence and having a vision of Him?”

    “No, Sir, I had no such experience.

    Junaid then became a liltle upset and asked: “Well, when you came to Muzdalifah, did you promise that you would give up vain desires of the flesh?”

    “Sir, I paid no heed to this.”

    “You did not then come to Muzdalifah at all.” Then he asked: 0?Tell me, did you happen to catch glimpses of Divine Beauty when youmoved round the House of Allah?”

    “No, Sir, I caught no such glimpses.”

    “Then, you did not move around the Ka’bah at all.” Then he said: “When you made Sa’i (running) between the Safa and the Marwa, did you realize the wisdom, significance and objective of your effort?”

    “Sir, I was not at all conscious of this.”

    “Then you did not make any Sa’i!” Then he asked: “When you slaughtered an animal at the place of sacrifice, did you sacrifice your selfish desires as well in the way of Allah?”

    “Sir, I failed to give any attention to that!”

    “Then, in fact you offered no sacrifice whatever.”

    “Then when you cast stones at the Jamarahs, did you make a resolve to get rid of your evil companions and friends and desires?”

    “No, Sir, I didn’t do that.”

    “Then, you did not cast stones at all”, remarked Junaid regretfully, and said:

    “Go back and perform Hajj once again, giving due thought and attention to all the requirements, so that your Hajj may bear some resemblance with Prophet Ibrahim’s Hajj, whose faith and sincerity has been confirmed by the Qur’an:

    Ibrahim who carried out most faithfully the Commands (of his Lord).” (53:37)

    A similar point is made by an anonymous Celtic source, who admonished pilgrims in his own time and circumstance:

    Coming to Rome, much labor and little profit! The King whom you seek here, unless you bring Him with you will not find Him.
