Extraordinary Popular Idiocies

 

No matter how incompetently the current president handles crises, from the toll taken on the nation’s health and economy by the coronavirus to the nationwide protests in response to the police murder of George Floyd, his supporters, followers, and enablers continue giving him a free pass. No evidence makes an impression on them.

 

The coronavirus is a plot by Democrats to make the current president look bad! No, he makes himself look bad, in the same way that those pants don’t make you look fat – your fat makes you look fat. And the George Floyd protesters need to be dominated in the streets, because that’s what a strong leader does! Never mind that it is the behavior of a tinpot dictator, not the leader of a nation of laws guaranteeing the freedoms of speech and peaceable assembly.

There’s the word “peaceable” that reactionaries have hung their hats on for centuries as an excuse to violently quell protests. If only some of the protesters can be goaded into violence by agents provocateurs planted among them by law enforcement agencies or private reactionary groups, then the police employees in riot armor can have license to start swinging their clubs and firing tear gas canisters and rubber bullets into the crowds. In the ensuing confusion, it’s difficult for reporters or other independent investigators to locate and prove the identity of the provocateurs.

Too many people believe, in the end, only what they want to believe, and do not care to trouble themselves any further with truthful details. It’s simpler that way, comforting really. Observational evidence will not convince them to change their minds. To use an example from the natural world, through the years many gardeners and even some professional horticulturists have believed that watering plants in sunshine will scorch the plants’ leaves on account of a supposed magnifying lens effect from water droplets.

Not only has this myth been scientifically disproved, but the evidence there is no validity in it is plain for anyone to see who has watered annual flowering plants tightly packed in a hanging basket or pot. No escaping getting water on the foliage there, and those plants appear to get along alright, and better than they would if the worried gardener had withheld the spray of water waiting for a cloudy day. Yet many continue to believe, because they would rather believe the story their mind and culture invents for them than what the plants themselves are showing. We’re alright! Thanks for the water on a hot, sunny day! Here’s a rainbow for your trouble!

The Glass Half Full

 

“And yet it moves.” — Galileo Galilei (1564-1642)

In an idiotic stunt on her Fox News television program on September 6, right wing commentator Laura Ingraham thought it would be good fun to upset liberals by sticking plastic straws and incandescent light bulbs into a slab of cooked meat and then sucking on one of the straws. The stunt revealed more about her emotional immaturity and that of her viewers who might have enjoyed the bizarre demonstration than it did about the ultimate worth of the causes she was mocking. That wasn’t her point, of course; the point for people like Ms. Ingraham and her fans is provoking liberals merely for the dubious enjoyment of provoking liberals, an attitude that displays all the maturity of a seventh grader shooting spitballs from the back of a classroom.


Оптимист и пессимист
An Optimist and a Pessimist, an 1893 painting by Vladimir Makovsky (1846-1920).

The unwillingness of bad faith media figures like Laura Ingraham to honestly and substantively discuss issues such as the environment generally, and the Green New Deal in particular, reveals their worries about how environmental initiatives like the Global Climate Strike may disrupt their lives and worldviews, and how because of their fears they resent the people backing the initiatives. They see it all as an infringement on their liberty rather than as a concession to sharing limited resources and playing nice with those unlike themselves. To them, it is not a matter of viewing the relative fullness or emptiness of a glass as it is a matter of resenting the people telling them that for the health of the planet and all its inhabitants, flora as well as fauna, all of us had better accept the situation of a glass not entirely full because constant demands by a relative few for an always full glass are causing environmental degradation and eventually, perhaps sooner rather then later, the glass will be empty for everyone.

But that’s what environmental science is telling us. Getting upset about it or denying it and hiding one’s head in the sand is not going to change it, any more than immature and unhelpful behaviors have ever changed other scientific realities. Worse yet is attacking the messengers in a bad faith attempt to disregard the messages. Why disregard clear, coherent messages? Because they disrupt the status quo for powerful people with vested interests in keeping things as they are, in continuing the business as usual of corporate profiteering at the expense of the long term habitability of the commons. Right wing pundits may not always consciously carry water for corporate exploiters of the environment and of workers, but since their interests often align with them the result is the same. The pundits know their audience is uniquely susceptible to fear and hate mongering, and they peddle those wares regularly to enrich themselves.


In this talk Noam Chomsky gave in April 2019 in Boston, Massachusetts, he looked back at the original New Deal to examine how the Green New Deal promises to change economic relationships while enacting energy and environmental initiatives.

 

The Green New Deal is felt as a threat by right wingers and by entrenched corporate interests because its environmental initiatives will reach into and change the entire economy, and that’s something they cannot help but see any other way than as a negative, a glass half empty. The privileges of white people generally, and of rich people in particular, will be eroded during these economic changes, and that’s a good thing for everyone else and for the planet, because the over extension and abuse of those privileges has been largely responsible for getting all of us into this mess in the first place. No matter how the over privileged feel about the changes, they will have to accept them and get used to them, because the alternative for them is grimmer still, as well as for everyone on our lifeboat Earth as it continues moving around the Sun.

Made in the Shade

 

For the home gardener or professional landscaper who absolutely must work in the sun on a hot day, there are no satisfactory ways to temporarily create sizable shaded areas. Beach umbrellas offer only a small circle of shade, can become dangerous projectiles in the wind, and at any rate are configured for people to sit under, not stand upright under, to gain their protection.

 

A portable canopy, such as may be found at a farmer’s market or a flea market, where it shades a seller’s wares, as well as the seller and any buyer, offers a sizable area of shade but is not as portable as one would like if the need arises to pick it up and move it several times during an afternoon of garden work. Four-legged canopies are also unsuitable on uneven ground, where they are likely to tip even without encouragement from a breeze. Preventing tipping requires the use of sandbags or other weights, and after a few repetitions setting up a so-called portable canopy becomes a real chore.

Those are two of the more portable, easier to set up options. Other methods of creating shade, such as deploying sail shades, are hardly portable at all. The Labor Day weekend is the traditional end of summer in the United States, yet there is still plenty of hot weather in store for September and even into October. Working in a sunny garden would be more pleasant with the assistance of a device that is easily workable, portable, and gives a sizable amount of shade. What follows are guidelines for the inventor or inventors of such a sorely needed garden companion.

1) In order to be useful, the device should shade an area no less than 100 square feet, and still fold up compactly enough to fit in a small kit bag. It should weigh less than 20 pounds.

2) The device should remain stable on uneven ground and in the wind, though obviously within reason in both cases, and it should do so without the use of heavy weights.

3) One reasonably fit person should be able to erect the device or fold it up within a minute, and it should be easy for that person to move the device from one location to the next, also within a minute.

4) The shading material should be shade cloth with a density ranging from 60 to 80 percent, which allows cooling breezes through, is lighter than a more tightly woven fabric, and remains more stable in the wind.

5) The supports should be strong, light, and corrosion resistant. Use of spikes to anchor the device is inadvisable since shallowly penetrating spikes can be unreliable, and deeply penetrating ones negate portability.

6) Ideally it should cost less than $100, and definitely no more than $200, even though it should be able to take some rough treatment and last a decade or more.

Is that too much to ask? Certainly it may be too late to have the new Shade Giver ready this year, but surely by next year, when summer heat starts seeping in by April or May, some enterprising person will have created a prototype that could become the new Gardener’s Friend. Perhaps instead of a sail it will resemble one of the shells of the Sydney Opera House. Whatever the design of the device, it should bring sweet relief to those who must labor under the hot sun and still not hurt their backs or pocketbooks. In these warming times, asking for the protection provided by shade has become a necessary request.

Saving Up for a Rainy Day

 

Battery storage has long presented a conundrum to renewable energy enthusiasts who tout the relatively benign environmental footprints of wind and solar power. The batteries can contain toxic metals and chemicals which cause environmental damage in mining and formulation, and then again when they have exhausted their usefulness and users need to somehow safely recycle or dispose of them.

For a time, it seemed the answer for homeowners using a solar array was to sell excess power produced during the day to the power company and then draw on grid power at night and on cloudy days. These grid-tied systems effectively used the power company as storage, mostly dispensing with the need for a bank of batteries at home. Unfortunately for homeowners with grid-tied systems, it appears power companies are backing away from those setups in order to protect their equipment and to maintain tighter control over power generation.

Power companies have been investing in their own renewable energy production as costs go down. Since there is no external backup for the electricity generated by the power company, the power companies need to employ huge amounts of batteries. Batteries have improved in the past generation both in toxicity and length of usable life from the days of lead acid batteries. Improvement does not mean they are exactly environmentally friendly. The problem comes down to relative harm, such as whether it is less harmful to the environment to drive an electric car when the source for its electricity is a coal burning power plant.

An illustration of the relationship of renewable energy to energy storage from the German cartoonist Gerhard Mester (1956-). Panel 1: “More solar energy!!” Panel 2: “More wind energy!” And in the last panel: “More energy storage!” Incidentally, Germany is a world leader in solar energy production despite receiving less sunlight than many other industrialized nations.

Nothing people do technologically has zero impact on the environment, and arguments from the extremes of both sides of the tug of war between those in favor of continued use of fossil fuels and those who want greater reliance on renewable energy are neither accurate nor helpful. Continuing the status quo of burning fossil fuels for most energy production is clearly a path to environmental catastrophe, while renewable energy production does not have quite as low an impact on the environment as some enthusiasts suggest. It is in the batteries especially that renewable energy has an unfavorable impact.

Nevertheless, in countries with higher renewable energy production than the global average the air is cleaner and greenhouse gas emissions are lower. Because the sun doesn’t always shine and the wind doesn’t always blow, the key to minimizing reliance on batteries, the most toxic element in renewable energy use, is diversification of power sources supplying the grid, from geothermal to hydroelectric. None of these methods of supplying the power necessary for humanity’s modern lifestyle are perfect, but they are all better than the alternative of continuing down the path of polluting the air and warming the planet. The two biggest obstacles to switching the United States to 100 percent renewable energy are the fossil fuel industry interests entrenched in national politics, and battery technology. Of the two, the latter will be more easily overcome by a concerted effort, and with time the new technology will push out the former technology and its moneyed adherents as obsolete and destructive. But will it be soon enough?

Love of Life

 

“To see a World in a Grain of Sand
And a Heaven in a Wild Flower,
Hold Infinity in the palm of your hand
And Eternity in an hour.”
— William Blake (1757-1827), Auguries of Innocence

Biophilia – love of life – is a term popularized by the American biologist and naturalist Edward O. Wilson in his research and books of the last two decades of the twentieth century. Mr. Wilson was interested in how humans appear to require some connection with nature no matter how much the modern world tends to divorce them from that connection. City dwellers in particular may be live amidst steel and concrete structures to such an extent that they never step on grass in the course of an average day, but they still will find comfort at home in tending a few houseplants and a pet or two. Mr. Wilson proposed that the need to maintain a connection with nature was so pervasive in humans that it went beyond culture to genetics, and was therefore innate and undeniable. Humans may pretend to be above nature and separate from it, but their genetics and behavior said otherwise.

Scientific research since then has confirmed Mr. Wilson’s hypothesis, some of it confirming common sense notions such as how hospital patients with window views of trees and greenery appeared to recover faster than ones with a view of the building next door. The idea of biophilia itself appeals to common sense, but science needs to quantify things, and that’s for the best because there have after all been other notions in the past which seemed common sense, such as the Sun revolving around the Earth. Lately there has been a resurgence in belief that the Earth is flat, though it’s hard to tell just how seriously Flat Earthers expect to be taken by everyone else, or even by themselves.

Everyday proof of biophilia, however, seems so commonplace that it is hard to refute. Still, there are people who live for making their environment as sterile and devoid of nature as possible, and it seems there are more of them now than ever. Children especially seem to have withdrawn from nature both on their own and because of their parents’ protective instincts. Children now spend an inordinate amount of their time in front of screens, and much of the remainder of their time is structured education or play. They are seldom left on their own to scratch around in the dirt in their backyards and observe the ants at work, as Edward O. Wilson himself did for countless hours as a youngster and, indeed, as an adult, since his specialty as a biologist has been myrmecology, the study of ants.

Recent appraisals of the value of Central Park’s 1 and 1/4 square miles of prime real estate in the middle of Manhattan are well over $500 billion. May biophilia influence New Yorkers for generations to come so that they continue to prize Central Park for its connection to nature rather than its speculative value in dollars.

The steep drop in hands-on discovery of nature among the latest generation does not bode well for future conservation measures when those children grow up and start making their own decisions. Reading about a tree in a book can take a person only so far without the furtherance of education granted by resting under the shade of a tree on a hot day. Even the tactile act of reading a paper book, its pages made from trees, gives the senses a greater depth and breadth of perception than reading from an electronic screen. We are animals, with the senses of animals, and we engage the world through those senses every bit as much as we engage it with our brains, even when we are cut off from nature. But with a lack of input from our senses our decisions about the natural world are likely ill-informed, and much as we might try to help conserve animals, plants, and resources, we are not doing as much as we could because they are not part of our everyday world. How can you love the natural world which supports you if you cut yourself off from it and avoid embracing it with not only your intelligence, but with all your senses so that you can feel it as well as know it, and understand thereby you are a part of it and not separate from it?

Seeing is Believing

 

“God does not play dice with the universe.”* ― Albert Einstein (1879-1955)

 

There are patterns throughout nature, from the rhythm of waves striking the shore, to the sand dune crests farther up the beach, to the leaves and flowers on plants and trees inland. Many of those patterns arise because of physical constraints operating through a medium, for instance the waves rise and fall regularly due to tidal influences from the Moon above and gravity from the Earth below, while sand grains in the dunes react to wind and water, and leaves and flowers allocate space for themselves in tune with the Sun and their plant neighbors.

An Italian mathematician of the 13th century named Leonardo Fibonacci, more commonly known just as Fibonacci, described natural patterns mathematically and he has since become well known for the Fibonacci sequence of numbers that add to each other infinitely, and for the Golden Ratio of 1.618, denoted in equations by the Greek letter Phi, which when employed in the Fibonacci sequence eventually yields Fibonacci spirals on a large scale. Less well known is that Fibonacci advocated the change from Roman numerals to Hindu-Arabic numerals in his 1202 book Liber Abaci, a book on calculations.

 

The shell of the nautilus is often cited incorrectly as a Fibonacci spiral. It is actually a logarithmic spiral. For whatever reason, the idea of Fibonacci spirals has taken hold popularly on the internet, to the point that some people appear eager to impose Fibonacci spirals on nature where patterns either hardly exist, or where they could be more accurately described with some other mathematical model. Perhaps the appeal lies in being able to ascribe patterns to a model proposed by one man, and saying “Fibonacci” has a more poetic feel than “logarithmic”. At any rate, there are many more patterns evident in nature than can be put down to chance, and that after all is the definition of a pattern.

Baraka is a 1992 non-narrative film directed by Ron Fricke, with music by Michael Stearns. Fricke has described his film as a “guided meditation”. Baraka means “blessing” in a multitude of languages.

We seem to prefer patterns over chance, and order over chaos, and therefore we sometimes struggle to impose a pattern where perhaps none exists. It comforts us. It can even be a matter of belief. Some of us, maybe most of us, find it unsettling to contemplate a natural world and a universe where things happen randomly with no rhyme or reason. How can you set a schedule for yourself and your family in such a universe when you are unsure what might happen from one moment to the next? How can you plan your life, if you are so inclined? Depending on your belief in the reliability and predictability of the patterns you see in nature, you may be able to conduct your daily life with some confidence everything will go mostly as planned. With that in mind as you go about your everyday affairs, you may take time to notice how the patterns in the natural world around you guide your beliefs, whether or not you believe there is, in turn, someone or other guiding those patterns.
