OLD SCHOOL:

Safety First, Fashion Second as Schoolkids View an Eclipse (Eliza Berman, 1963, LIFE)


If you ever have the chance to view an eclipse, you’d do well to take a tip from the 1963 fifth grade class at the Emerson School in Maywood, Illinois. Wielding cardboard boxes and knives that today would surely get a kid suspended, the students demonstrated for LIFE’s readers how to safely look at an eclipse.

During the solar eclipse of 1960, hundreds of people had suffered permanent eye damage from looking directly at the sun. With help from the Illinois Society for the Prevention of Blindness, Emerson students avoided the same fate by building Sunscopes, pinhole camera-like contraptions that indirectly project an image of the sun. The magazine offered instructions for those wanting to replicate the project at home:

WE ARE ALL DESIGNIST:

The “blind spot” in science that’s fueling a crisis of meaning (Adam Frank and Marcelo Gleiser and Evan Thompson, 3/07/24, Big Think)


Cosmology tells us that we can know the Universe and its origin only from our inside position, not from the outside. We live within a causal bubble of information — the distance light traveled since the Big Bang — and we cannot know what lies outside. Quantum physics suggests that the nature of subatomic matter cannot be separated from our methods of questioning and investigating it. In biology, the origin and nature of life and sentience remain a mystery despite marvelous advances in genetics, molecular evolution, and developmental biology. Ultimately, we cannot forgo relying on our own experience of being alive when we seek to comprehend the phenomenon of life. Cognitive neuroscience drives the point home by indicating that we cannot fully fathom consciousness without experiencing it from within.

Each of these fields ultimately runs aground on its own paradoxes of inner versus outer, and observer versus observed, that collectively turn on the conundrum of how to understand awareness and subjectivity in a Universe that was supposed to be fully describable in objective scientific terms without reference to the mind. The striking paradox is that science tells us both that we’re peripheral in the cosmic scheme of things and that we’re central to the reality we uncover. Unless we understand how this paradox arises and what it means, we’ll never be able to understand science as a human activity, and we’ll keep defaulting to a view of nature as something to gain mastery over.

Each of the cases just mentioned — cosmology and the origin of the Universe, quantum physics and the nature of matter, biology and the nature of life, cognitive neuroscience and the nature of consciousness — represents more than an individual scientific field. Collectively they represent our culture’s grand scientific narratives about the origin and structure of the Universe and the nature of life and the mind. They underpin the ongoing project of a global scientific civilization. They constitute a modern form of mythos: They are the stories that orient us and structure our understanding of the world.

For these reasons, the paradoxes these fields face are more than mere intellectual or theoretical puzzles. They signal the larger unreconciled perspectives of the knower and the known, mind and nature, subjectivity and objectivity, whose fracture menaces our project of civilization altogether. Our present-day technologies, which drive us ever closer to existential threats, concretize this split by treating everything — including, paradoxically, awareness and knowing themselves — as an objectifiable, informational quantity or resource. It’s precisely this split — the divorce between knower and known and the suppression of the knower in favor of the known — that constitutes our meaning crisis. […]


We call the source of the meaning crisis the Blind Spot. At the heart of science lies something we do not see that makes science possible, just as the blind spot lies at the heart of our visual field and makes seeing possible. In the visual blind spot sits the optic nerve; in the scientific blind spot sits direct experience — that by which anything appears, shows up, or becomes available to us. It is a precondition of observation, investigation, exploration, measurement, and justification. Things appear and become available thanks to our bodies and their feeling and perceiving capacities. Direct experience is bodily experience.

We collapse the wave function.

WE JUST BICKER OVER THE DESIGNER:

PODCAST: Samuel Wilkinson — What Evolution and Human Nature Imply About the Meaning of Our Existence (Skeptic, 3/04/24)

With respect to our evolution, nature seems to have endowed us with competing dispositions, what Wilkinson calls the dual potential of human nature. We are pulled in different directions: selfishness and altruism, aggression and cooperation, lust and love.

By using principles from a variety of scientific disciplines, Yale Professor Samuel Wilkinson provides a framework for human evolution that reveals an overarching purpose to our existence.

Wilkinson claims that this purpose, at least one of them, is to choose between the good and evil impulses that nature has created within us. Our life is a test. This is a truth, as old as history it seems, that has been espoused by so many of the world’s religions. From a certain framework, Wilkinson believes that these aspects of human nature—including how evolution shaped us—are evidence for the existence of a God, not against it.

THE PRIMACY OF tHE oBSERVER:

The surprising origins of wave-particle duality (Ethan Siegel, 2/20/24, Big Think)


One of the most powerful, yet counterintuitive, ideas in all of physics is wave-particle duality. It states that whenever a quantum propagates through space freely, without being observed-and-measured, it exhibits wave-like behavior, doing things like diffracting and interfering not only with other quanta, but with itself. However, whenever that very same quantum is observed-and-measured, or compelled to interact with another quantum in a fashion that reveals its quantum state, it loses its wave-like characteristics and instead behaves like a particle.

TRYING TO BUILD WITHOUT A FOUNDATION:

Free Will, Pragmatism, And The Things Best Left Unsaid (David Kordahl, 2/26/24, 3Quarks)

Though William James’s pragmatism is a variety of empiricism, it’s easy to see why it never caught on among natural scientists. (The physicists I’ve read who gesture toward pragmatism instead cite Charles Sanders Pierce, who was himself a mathematician and natural scientist.) Most natural scientists are motivated to discover something about the objective, mind-independent properties of nature, not just relations between human concepts, constrained by our environment.

Pragmatism stipulates that we recognize scientific theories as human tools, levers that we use to augment our possibilities. We should adopt whatever theories prove most helpful. To reproduce another emphasized maxim of James: “Theories thus become instruments, not answers to enigmas, in which we can rest.”

Reason fails at the first hurdle, when it can not establish that anything is mind-independent.

MORALITY IS THE CONTROL OF EMOTION:

Rock, Paper, Scissors, and Race (ARNOLD KLING, FEB 23, 2024, In My Tribe)

In thinking about The End of Race Politics, a new book by Coleman Hughes, I came up with a description of the race debate using the metaphor of the game Rock, Paper, Scissors. I assign a stance to each of the three symbols.

Rock is individualism. Treat people as individuals, not as members of a race.

Paper is equalitarianism. Treat differences in average outcomes by race as evidence of unfairness.

Scissors is realism. Explain differences in average outcomes by race by appealing to heredity and culture.

In the game, paper covers rock, scissors cuts paper, and rock breaks scissors. Translating from the metaphor, the most compelling argument against individualism is equalitarianism. The most compelling argument against equalitarianism is realism. And the most compelling argument against realism is individualism. […]

The problem with individualism (Rock) is that people intuitively find inequality offensive. If we treat people as individuals, and the resulting outcomes are unequal by race, this will not be acceptable. The unequal outcomes will be viewed as a sign that something is wrong with our society.

The problem with equalitarianism (Paper) is that it requires people to deny, implicitly or explicitly, that average differences by race in inherited or cultural characteristics can be significant. The realists want to confront the equalitarians over this.

The problem with realism (Scissors) is that it uncages the demon of racial stereotyping and prejudice. The individualists will insist that we should pay attention to differences across individuals, not differences across races.

CAIN WON:

Hunter-gatherers were violently wiped off the map by farmers, DNA reveals (Bronwyn Thompson, February 12, 2024, New Atlas)

Researchers from Sweden’s Lund University analyzed skeletons and teeth found in what is now Denmark, and found that 5,900 years ago, the region underwent a swift and total population change. Prior to this, Danish Mesolithic people of the Maglemose, Kongemose and Ertebølle cultures – genetically related to other Western European hunter-gatherers – were prominent inhabitants. But when Neolithic farmers arrived, an abrupt shift can be seen in DNA records, with next to no genetic contribution from the local hunter-gatherers.

Tracing the DNA timeline, the researchers could see that the hunter-gatherers had been swiftly wiped out by the late Stone Age, in what they suspect was a very bloody and very thorough takeover.

THE MUSIC OF THE SPHERES:

J.R.R. Tolkien, C.S. Lewis, and the Cosmic Music of the Beginnings: The Inklings expressed interest in ancient mythologies that described the creation of the world through music. (Robert Lazu Kmita, February 6, 2024, European Conservative)

However, the theological theory about music that is most similar to Tolkien’s vision presented in The Silmarillion (in “Ainulindalë,” “The Music of the Ainur”) is that of the extraordinary medieval saint and prophetess, St. Hildegard of Bingen (c. 1098-1179). As Barbara Newman has shown in her introduction to the critical edition of the musical work Symphonia armonie celestium revelatione (Symphony of the Harmony of Celestial Revelations), Hildegard asserts that God is the creator of music, while “the ultimate unmusical spirit was the devil.”

In one of her letters, Hildegard claims that, before committing the Original Sin, Adam’s voice had exceptional musical qualities: “In his voice was the sweetness of every harmonic sound, and of the whole art of music.” Upon hearing the music sung by Adam, the devil, terrified and filled with envy, recalls the beauty of God’s celestial hymns that he had heard before the fall. What follows, we know from the biblical text. From Hildegard’s vision, we learn about music of divine origin and about the fallen angel, who, unable to bear it, wanted to replace the divine harmony with his own musical creation.

The music of the Inklings
The closest of friends, Tolkien and Lewis, showed in some of their literary writings a special preference for a kind of doctrine about the creation of the world that can be named the ‘musical cosmogony.’ This might be a fitting and proper name for those ancient mythologies, including some mentioned above, that describe the creation of the whole world through music.

Beauty is objective

HUBBLE HUMBLING:

After 2 years in space, the James Webb telescope has broken cosmology. Can it be fixed? (Ben Turner, 12/22/23, Live Science)

But over the past decade, an alarming hole has been growing in this picture: Depending on where astronomers look, the rate of the universe’s expansion (a value called the Hubble constant) varies significantly.

Now, on the second anniversary of its launch, the James Webb Space Telescope (JWST) has cemented the discrepancy with stunningly precise new observations that threaten to upend the standard model of cosmology.

The new physics needed to modify or even replace the 40-year-old theory is now a topic of fierce debate.

“It’s a disagreement that has to make us wonder if we really do understand the composition of the universe and the physics of the universe,” Adam Riess, a professor of astronomy at Johns Hopkins University who led the team that made the new JWST measurements, told Live Science.

Relax, son, no one thought we understood.
