Hipbone’s Uncertainty Principle

Monday, February 5th, 2018

[ by Charles Cameron — divergent and convergent, expansive and focused thinking ]

Consider this:

Breath expands, then contracts the lungs. That’s basic.

Let’s apply it to the paradox above. I’d go with Dirac in my expansive, divergent phase, and Feynman for eventual convergence and verification.

Poetry is closely analogous to science in this regard.

Scripture in defense of a flat earth

Sunday, January 14th, 2018

[ by Charles Cameron — an antique KJV quote with modern relevance ]
.

An assistant and friend in my recovery unit is a Flat Earther. I’m always eager to learn more about non-conventional worldviews, so I was glad when he offered me a video in proof of his worldview — and stunned when, a couple of minutes into the video, I found this verse from Timothy 6.20:

O Timothy, keep that which is committed to thy trust, avoiding profane and vain babblings, and oppositions of science falsely so called:

Scripture mocking science in service of the flat-earthers?

It’s a popular message, apparently, in some literalist circles, whereas others note that the word translates the Greek of Timothy’s original “gnosis” — elsewhere always rendered “knowledge”.

No matter, false is false, whether it be science or knowledge.

If science is false — and we know that individual claims within scienve are falsifiable –the lunar and martian surfaces are probably in sound stages in Burbank, and Armstrong took only a very short walk for mankind.

For what it’s worth, the Hare Krishnas are sure about the moon landing being a hoax, too. But they say the moon is beyond the sun, so if the landing were real, it would probably have beeen on the Rahu planet, which most of us haven’t heard of, but which is responsible for eating the sun during eclipses:

In Hindu tradition, Rahu is the severed head of an asura called Svarbh?nu, that swallows the sun causing eclipses.

To my mind, that’s a more complex business than NASA’s explanation.

But back to the flat-earth, non-Rahu idea, all I can say is:

Armed Robotic Systems A.K.A. “Killer Robots” [sic]

Wednesday, November 15th, 2017

[Mark Safranski/ “zen”]

Dr. Robert Bunker emailed to alert me that the Strategic Studies Institute has released his monograph Armed Robotic Systems Emergence: Weapons Systems Life Cycles Analysis and New Strategic Realities. From the synopsis:

Armed robotic systems—drones and droids—now emerging on the battlefield portend new strategic realities not only for U.S. forces but also for our allies and future potential belligerents. Numerous questions of immediate warfighting importance come to mind with the fielding of these drones and droids that are viewed as still being in their experimental and entrepreneurial stage of development. By drawing upon historical weapons systems life cycles case studies, focusing on the early 9th through the mid-16th-century knight, the mid-19th through the later 20th-century battleship, and the early 20th through the early 21st-century tank, the monograph provides military historical context related to their emergence, and better allows both for questions related to warfighting to be addressed, and policy recommendations related to them to be initially provided.

Bunker correctly explains the degree to which this topic has already been overhyped and that Ai that could operate even at the level of “a trained animal” is at best a prospect for the near term future. To use an aerial analogy, autonomous combat droids today are not in the era of the fragile WWI biplane but really something closer to Orville and Wilbur Wright’s bicycle shop before Kitty Hawk. Bunker’s use of a historical, evolutionary framework for armed robotics is apt.

Nevertheless, the subject continues to captivate the media and our think tanks. Here for purposes of comparison was the 2014 CNAS report Prepare for Robotic Warfare by Robert Work, later Deputy Secretary of Defense under Presidents Obama and Trump, and CNAS VP Shawn Brimley. There are other similar studies to be found online. Driving this is the logical inevitability (which tech is far from catching up to) that robotic warfare systems, if done to economies of scale, would be effective force multipliers, especially for smaller powers or deep-pocketed private entities and insurgent groups.

Someday.

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.
