Derrick Jensen – Enchantment

There are those people in your life who you have yet to meet, whose words reached out to you from worn pages of a friend’s book you found as an interesting note on the floor. The words that rang through your Self like the gong of a bell echoing off the rocks of your foundation.  So that nothing else will ever sound quite the same. Their printed voice changed the songs you sing and the levels that you hear. Sometimes, in the purest of luck, you get to meet this person. You get to ask them how they are doing today. You get to listen to their voice speak like music playing notes right off the page and you get to sit down and ask them questions. If I were you, or maybe, if you were me… That person would be, Derrick Jensen and this, is the luckiest of days.

“We have a need for enchantment that is as deep and devoted as our need for food and water.”
― Derrick Jensen, The Culture of Make Believe

“Many Indians have told me that the most basic difference between Western and indigenous ways of being is that Westerners view the world as dead, and not as filled with speaking, thinking, feeling subjects as worthy and valuable as themselves.”
― Derrick Jensen

“In order to maintain our way of living, we must tell lies to each other, and especially to ourselves.”
― Derrick Jensen, Endgame, Vol. 1: The Problem of Civilization

“We were not meant for this. We were meant to live and love and play and work and even hate more simply and directly. It is only through outrageous violence that we come to see this absurdity as normal, or to not see it at all. Each new child has his eyes torn out so he will not see, his ears removed so he will not hear, his tongue ripped out so he will not speak, his mind juiced so he will not think, and his nerves scraped so he will not feel. Then he is released into a world broken in two: others, like himself, and those to be used. He will never realize that he still has all of his senses, if only he will use them. If you mention to him that he still has ears, he will not hear you. If he hears, he will not think. Perhaps most dangerously of all, if he thinks he will not feel. And so on, again.”

“I had broken the most basic commandment of our culture: Thou shalt pretend there is nothing wrong.”
― Derrick Jensen, A Language Older Than Words

“So many indigenous people have said to me that the fundamental difference between Western and indigenous ways of being is that even the most open-minded westerners generally view listening to the natural world as a metaphor, as opposed to the way the world really is. Trees and rocks and rivers really do have things to say to us.”

The Heart is not a Pump

AnthroMed

To any doctor trained in today’s medical schools, the idea that the heart may not be a pump would, at first sight, appear to be about as logi­cal as suggesting that the sun rises in the West or that water flows uphill. So strongly is the pump concept in­grained in the col­lective psyche that even trying to think otherwise is more than most people can man­age. Yet Rudolf Steiner, a man not given to unscien­tific or slipshod thinking, was quite clear on the matter and reiterated time and again that the heart is not a pump. “The blood drives the heart, not the heart the blood.”




Ralph Marinelli* and his co-workers published a paper refuting the generally-accepted pressure-propulsion premise. For a start, they draw atten­tion to the sheer volume of work which the heart would have to do if it were solely responsible for pumping inert blood through the vessels of the circula­tory system. Blood is five times as vis­cous as water. According to the propul­sion premise the heart would have to pump 8000 liters of blood a day in a body at rest and considerably more during ac­tivity, through millions of capillaries the diameters of which are sometimes smaller than the red blood cells them­selves – a huge task for a relatively small, muscular organ weighing only 300 grams.

Once the questions start being asked, the anomalies in currently accepted dogma become apparent. For instance, if blood were pumped under pressure out of the left ventricle into the aorta dur­ing systole, the pressure pulse would cause the aortic arch to try and straighten out, as happens in any Bourdon tube pressure gauge. In practice the exact oppo­site happens; the curve increases, indi­cating that the aorta is undergoing a nega­tive, rather than a positive, pressure.




Another paradoxical finding con­cerns the mechanics of fluid flow under pulsatile pressure. When a pressure pulse is applied to a viscous fluid in a closed vessel, the liquid initially resists move­ment through its own inertia. The pres­sure, therefore, peaks before the fluid velocity peaks. In the aorta, exactly the opposite happens where a peak flow markedly precedes peak pressure, a fact which was observed in 1860 by Chaveau and Lortet. So just what is going on in­side the circulation?

Misleading sketch of the heart by Leonardo do Vinci (1). The left ventricle wall is shown uniform in thickness as it would he in a pressure chamber. Actually the left ventricle wall thickness varies by about 1800% as Marinelli and his group measured in bovine hearts (2). The apex wall is so soft and weak that it can be pierced with the index finger. The peculiar variability in the ventricular wall thickness is not in keeping with the heart as pressure generator. However, Leonardo’s Notebooks has been used in most biology, physiology, and medical texts during the last few hundred  years as well as in most modern anatomy texts in the last decades (3). Thus, false sketches have served to bear witness to a false premise.

As Marinelli et al point out, the pres­sure-propulsion model of blood circula­tion rests on four major premises: (1) blood is naturally inert and must, there­fore, be forced to circulate; (2) there is a random mix of formed particles in the blood; (3) blood cells are under pressure at all times; (4) blood is amorphous and is forced to fill its vessels and take on their form.

The Very Curious Little Soliton

 

In 1834, a man sits beside a canal. It is summer. He watches boats moving up and down the waterway. Suddenly, one boat stops abruptly and shoves a curious wave of water forward. The man stands and observes this singular wave, which passes leaving only flat water behind it. John Scott Russel stands. The wave is still moving. Disappearing from sight. He leaps on his horse. He pursues it, overtakes it, and observes it over perhaps two miles of waterway. It holds its shape, and only gradually diminishes in height. Very strange. Very curious.

Russel, an engineer, mathematician, and accomplished ship builder, was the first person to spot such a wave, follow it, and then write about it. He described called the wave a ‘wave of translation.’ Modern physics calls such singular traveling waves solitons.

What’s the big deal?

Throw a stone in a pond, and ripples spread. They spread out in concentric rings, and the rings split into more rings, and these split further. The rings begin to overlap as the taller rings overtake the shorter, and they gradually all become imperceptible as the energy of the stone spreads and is redistributed across the entire surface of the pond. Not so for the soliton. A soliton, as Russel famously chased, can travel over long distances without losing its form or its energy.

Oh, and solitons occur in not only water but light (electromagnetism) as well as in phonons (thermodynamics) and potentially in gravity waves.

You might be a soliton if:

  1. You are a traveling wave in some medium
  2. You hold your shape as you travel – you don’t spread out or fall apart into other waves.
  3. You are a neat well defined little envelope of energy – you are not here, you arrive and pass, and then you are gone!
  4. If you ever cross paths with another soliton, you can pass through each other unchanged.

Thunderbolts – Turning Sound Into Light

by Jimmy Mikecz

What if sound didn’t only flow through matter but could produce unexpected phenomena like light? Research in sound has revealed the capacity of sound to influence matter in a way that produces light. The phenomenon of sonoluminescence (SL) is one example of this relationship.

The Equipment.

“If you want to find the secrets of the universe, think in terms of energy, frequency, and vibration.”
― Nikola Tesla

Sonoluminescence occurs when high-frequency sound vibrates tiny gas bubbles to reach star-like temperatures and emit flashes of light. The mechanism of sonoluminescence is not fully understood but its occurrence is well documented. As SL researchers probe deeper into the phenomenon, they have found that current fluid dynamic equations cannot explain why it happens. SL is a natural phenomenon as well, and marine biologists observe some species of shrimp using it as an attack against other creatures. It is the bridge between sound and light and can offer a deeper understanding of nature’s laws.

Sonoluminescence

In a study at UCLA called Sonoluminescence: How Bubbles Turn Sound into Light, scientists S.J. Putterman and K.R. Weninger explore the mathematics and phenomenology of sonoluminescence. It is known that this phenomenon is caused by the rapid expansion and contraction of a bubble. This is known because the broad-band UV light emitted appears at a frequency, though not continuously. Think of a strobe light as an analogy where flashes of light last only pico-seconds (trillionths of a second.) According to Prof. Putterman, the phenomenon of sonoluminescence can heat bubbles up to tens of thousands of degrees. The surface of these bubbles burns at about 20,000 K (~35,000 °F) and look like “little stars.”

The IllustrisTNG Project – Large Scale Cosmological Simulation

TNG

Somehow these guys are still thinking “Big Bang” and “Dark Matter”.

From their website:

The IllustrisTNG project is a suite of state-of-the-art cosmological galaxy formation simulations. Each simulation in IllustrisTNG evolves a large swath of a mock Universe from soon after the Big-Bang until the present day while taking into account a wide range of physical processes that drive galaxy formation. The simulations can be used to study a broad range of topics surrounding how the Universe — and the galaxies within it — evolved over time.

Scientific Goals

The goals of constructing such a large and ambitious simulation suite are to shed light on the physical processes that drive galaxy formation, to understand when, why, and how galaxies are evolving into the structures that are observed in the night sky, and to make predictions for current and future observational programs to broaden and deepen our understanding of galaxy formation. These goals are achieved not in a single step, but rather through a series of extended analyses of the simulations, each targeting specific science questions. Some of the first questions that have been specifically addressed using the TNG suite are characterizing the stellar masses, colors, and sizes of galaxies, understanding the physical origin of the heavy element (metallcity) distribution in galaxies and galaxy clusters, drawing connections between the presence of dynamically important magnetic fields and the observed radio emission from galaxies, and the clustering signal of galaxies and matter on large scales. Subsequent studies are expected to canvass an even broader range of topics.
