Edgar Allen Poe Said Intuitive Leaps Should Be Added to Deduction and Induction as Paths to Knowledge

(p. C7) In an 1848 lecture, Edgar Allan Poe—the “Raven” guy, the progenitor of detective stories and spooky science fiction, who married his 13-year-old cousin, and died after being found insensibly drunk and wearing (somehow the most unsettling detail of all) another man’s clothes—this ink-stained wretch described a startling number of what would turn out to be prominent features of modern cosmology, including the big bang, the big crunch and the unity of space-time.

. . .

Where Poe sent audiences winging around the universe (or multiverse, another concept he seems to have anticipated), Mr. Tresch keeps to a steady course. He approaches Poe’s uncanny lecture—and its published version, the prose poem “Eureka”—not as a crazy fever dream, but as an inspired series of leaps from a firm grounding in fact.

. . .

In his lecture on the universe, Poe turned this method upside down: Here he used fiction in the service of science. He began by citing a letter, purportedly written in 2848, that mocked the primitive methods of 1848, when overconfident scientists believed that deduction and induction were the only paths to knowledge. Intuitive leaps, Poe insisted, could yield insights of their own. One such “soul-reverie” led him to argue that the universe began when “a primordial Particle” erupted outward in every direction. Everything that has happened since then is the result of the interplay of “the two Principles Proper, Attraction and Repulsion.” So far, so reasonable, by the lights of 21st-century cosmology. Still, plenty of what Poe went on to assert is either flatly wrong, ludicrously wrong, or outside the realm of cosmology properly defined, e.g., his suggestion that if there are multiple universes, each might have its own god.

“The Raven,” “The Tell-Tale Heart,” “The Pit and the Pendulum”: As far as Poe was concerned, these gloomy triumphs of his imagination—all the poems and short stories that have made him immortal—counted for less than his cosmic speculations, which he considered the pinnacle of his career. “I could accomplish nothing more since I have written Eureka,” he told his mother-in-law/aunt. So imagine his dismay when, after requesting a print run of 50,000 copies, his publisher granted him only 500, and even these didn’t sell. A year later, Poe would spend a calamitous day and night in Baltimore, drinking himself to oblivion. He died at 40.

Had he lived, he would have found it ever more difficult to “revolutionize the world of Physical & Metaphysical Science.” Mr. Tresch, who teaches at the Warburg Institute at the University of London and has previously written about Romanticism and science in 19th-century France, shows that the last years of Poe’s life coincided with increased regimentation in American thought. New organizations such as the American Association for the Advancement of Science began applying rigorous standards to scientific discourse. “Eureka” was “precisely the kind of publicly oriented, freewheeling, generalizing, idiosyncratic, and unlicensed speculation that the AAAS was created to exclude,” he writes.

Researchers and Entrepreneurs Experiment with Once-Taboo Geoengineering Projects to Reverse Global Warming

(p. A3) Dumping chemicals in the ocean? Spraying saltwater into clouds? Injecting reflective particles into the sky? . . .

These geoengineering approaches were once considered taboo by scientists and regulators who feared that tinkering with the environment could have unintended consequences, but now researchers are receiving taxpayer funds and private investments to get out of the lab and test these methods outdoors.

. . .

In Israel, a startup called Stardust Solutions has begun testing a system to disperse a cloud of tiny reflective particles about 60,000 feet in altitude, reflecting sunlight away from Earth to cool the atmosphere in a concept known as solar radiation management, or SRM. Yanai Yedvab, Stardust chief executive and a former deputy chief scientist at the Israel Atomic Energy Commission, wouldn’t disclose the composition of the proprietary particles.

Yedvab said Stardust has raised $15 million from two investors and has conducted low-level aerial tests using white smoke to simulate the particles’ path in the atmosphere. After the company completes indoor safety testing, it intends to conduct a limited outdoor test of the dispersion technology, monitoring devices and particles in the next few months, Yedvab said.

. . .

Experiments aimed at cooling the atmosphere by reflecting sunlight away from Earth are an attempt to mimic what happens when a volcano erupts. In 1991, Mount Pinatubo, an active volcano in the Philippines, spewed sulfur and ash into the upper atmosphere, lowering the Earth’s temperature by .5 degrees Celsius (.9 degrees Fahrenheit) for an entire year.

Isaacson Reprises His Themes of “Science, Genius, Experiment, Code, Thinking Different” in Book on CRISPR

(p. 12) The landmark research that brought Doudna and Charpentier to the pinnacle of global acclaim has the potential to control future pandemics — either by outwitting the next viral plague through better screening and treatment or by engineering human beings with better disease resistance programmed into their cells. The technique of gene editing that they patented, which goes by the unwieldy acronym of CRISPR-Cas9, makes it possible to selectively snip and alter bits of DNA as though they were so many hems to take up or waistbands to let out. The method is based on defenses pioneered by bacteria in their ages-old battle against viruses.

. . .

The CRISPR history holds obvious appeal for Walter Isaacson, a biographer of Albert Einstein, Benjamin Franklin, Steve Jobs and Leonardo da Vinci. In “The Code Breaker” he reprises several of his previous themes — science, genius, experiment, code, thinking different — and devotes a full length book to a female subject for the first time.

. . .

Isaacson keeps a firm, experienced hand on the scientific explanations, which he mastered through extensive readings and interviews, all of which are footnoted.

“Momentum Around Solar Geoengineering Is Building Fast”

(p. A19) A few years ago, the idea of deliberately blocking the sun to combat climate change was taboo for scientists. But a lot can change in a short time.

As the disastrous effects of climate change mount, Congress has asked federal scientists for a research plan, private money is flowing and rogue start-ups are attempting experiments — all signs that momentum around solar geoengineering is building fast. The most discussed approach involves spraying tiny particles into the stratosphere to reflect sunlight and cool the planet. Other proposals include injecting sea salt into clouds to increase their reflectivity or using giant space parasols to block the sun.

It might all sound like dystopian science fiction, but some techno-futurists, like OpenAI’s chief executive, Sam Altman, are already normalizing it: “We’re going to have to do something dramatic with climate like geoengineering as a Band-Aid, as a stopgap,” he said in January [2024] at the World Economic Forum in Davos.

No one fully understands the risks of these technologies — which could include calamitous disruptions in weather — or how significant the benefits could be. I’m increasingly convinced that we should do more research on solar geoengineering.

. . .

. . . science is fallible precisely because it is a practice, a cooperative human activity. And as the moral philosopher Alasdair MacIntyre reminds us, engaging in a practice well requires exercising its virtues — which for science include transparency, honesty, humility, skepticism and collaboration.

Citizen Archeologists “Are Increasingly Making Important Discoveries”

(p. 11) The long, thin piece of metal looked like a scaffolding pole when Trevor Penny saw it on the banks of an English river last November [2023].

. . .

But his find that day was much more dramatic: a rusty Viking sword that had been there for more than 1,000 years.

. . .

When Mr. Penny, 52, realized what he had found, he contacted a local official responsible for identifying the public’s archaeological finds.

The discovery was “one further puzzle piece that can cast light on our shared heritage,” said that official, Edward Caswell, who documents Oxfordshire finds for the Portable Antiquities Scheme run by the British Museum.  . . .

“We do find Viking weapons, including swords, deposited in rivers in England,” said Jane Kershaw, an associate professor of archaeology at the University of Oxford.

Many such weapons have been found in the north and east of the country, Dr. Kershaw said. She called the sword a “rare example” of viking activity in the area.

“It is outside the normal find zone for these weapons,” she said. “But the Vikings, they were active in that area. There is a lot that we don’t know about their activities.”

Hobbyists are increasingly making important discoveries, and Dr. Kershaw said it was critical that they report their finds. “It’s hugely valuable information,” she said. “As long as they are recording it, this is having archaeology that otherwise would be lost.”

Dissenters from Orthodoxy Can Be Easily Blackballed When They Are Required to Write Diversity Statements

(p. A15) Amidst the explosion of university diversity, equity and inclusion policies, Texas Tech’s biology department adopted its own DEI motion promising to “require and strongly weight a diversity statement from all candidates.”

. . .

The biology department’s motion mandates that every search committee issue a report on its diversity statement evaluations. Through a Freedom of Information Act request, I have acquired the evaluations of more than a dozen job candidates.

To my knowledge, these documents—published in redacted form by the National Association of Scholars—are the first evaluations of prospective faculty DEI contributions to be made publicly available. They confirm what critics of DEI statements have long argued: That they inevitably act as ideological litmus tests.

One Texas Tech search committee penalized a candidate for espousing race-neutrality in teaching. The candidate “mentioned that DEI is not an issue because he respects his students and treats them equally,” the evaluation notes. “This indicates a lack of understanding of equity and inclusion issues.”

. . .

The biology department’s search committees also rewarded fluency in the language of identity politics. An immunology candidate was praised for awareness of the problems of “unconscious bias.” “Inclusivity in lab” was listed as a virology candidate’s strength: “her theme will be diversity, and she will actively work to creating the culture—e.g. enforce code of conduct, prevent microaggressions etc.”   . . .

Many critics rightly point out that diversity statements invite viewpoint discrimination. DEI connotes a set of highly contestable social and political views. Requiring faculty to catalog their commitment to those views necessarily blackballs anybody who dissents from an orthodoxy that has nothing to do with scientific competence.

Geology Scientists by a Large Majority Reject the Anthropocene as a New Epoch

(p. A1) The Triassic was the dawn of the dinosaurs. The Paleogene saw the rise of mammals. The Pleistocene included the last ice ages.

Is it time to mark humankind’s transformation of the planet with its own chapter in Earth history, the “Anthropocene,” or the human age?

Not yet, scientists have decided, after a debate that has spanned nearly 15 years. Or the blink of an eye, depending on how you look at it.

Risk of Bat Disease Spillover to Humans Is Small and Decreasing

(p. A15) The World Health Assembly in May is poised to divert $10.5 billion of aid away from tackling diseases such as malaria and tuberculosis. Instead, that money will go toward combating the threat of viruses newly caught from wildlife. The assumption behind this initiative, endorsed by the Group of 20 summit in Bali in 2022, is that the threat of pandemics from spillovers of animal viruses is dramatically increasing.

That assumption is almost certainly false. A new report from the University of Leeds, prepared in part by former World Health Organization executives, finds that the claims made by the G-20 in support of this agenda either are unsupported by evidence, contradict their own cited sources, or fail to correct for improved detection of pathogens. Over the past decade the burden and risk of spillover has been relatively small and probably decreasing. The Leeds authors conclude: “The implication is that the largest investment in international public health in history is based on misinterpretations of key evidence as well as a failure to thoroughly analyze existing data.”

. . .

It is a misconception that population growth or prosperity leads humanity to encroach on wildlife habitats. The poorest people in Africa encroach on forest wildlife by hunting for bush meat; when they grow richer, they shop for chicken or pork instead. Humans visited bat caves more frequently in the distant past.

. . .

The prospect of spending $31 billion a year on pandemic prevention, a third of which would be new money and a third diverted from other programs, provides an incentive for international bureaucrats to ignore or misrepresent evidence that the problem is small.

But a dollar spent on spillover can’t be spent on something else, and the evidence is clear that sanitation, nutrition and vitamins are more cost-effective ways to save lives in poor countries—from infectious diseases as well as other causes.

Good Scientific Questions Can Be Answered With Empirical Experiments: “In Science, Reality Rules”

(p. A17) . . . I hit it off with the legendary Columbia University physics professor and Nobel Prize winner I.I. Rabi, who discovered the basis for magnetic resonance imaging, among other techniques through which we access and harness the quantum world.

. . .

Naturally, our conversations often wandered across physics. I was full of theoretical ideas and quasi-philosophical speculations. Rabi pressed me—gently, with a twinkle in his eye, yet relentlessly—to describe their concrete meaning. In the process we often discovered that there wasn’t any!

But not always—and the questions that survived those dialogues were leaner and stronger. I internalized this experience, and since then my inner Rabi (he died in 1988) has been a wise, inspiring companion.

. . .

Fully worked-out answers to good scientific questions should include solid experimental prospects.

That is a surprisingly controversial view today, as some prominent philosophers of science promote a “post-empirical physics” that doesn’t require proof, or evidence. And there’s no doubt that physically inspired mathematics, or for that matter pure mathematics, can bring people great joy. But I lean toward Rabi’s attitude: In science, reality rules.

. . .

Another characteristic of most good questions is that the answer is just a little bit out of reach. It should not be too obvious, but it should not be utterly inaccessible either.

. . .

The foolproof way to find good questions is to come up with a lot of them and then throw out the ones that are too vague, too easy, too hard or too inconsequential.

All Conclusions in Science Are Open to Further Inquiry

(p. C3) Victory is often temporary. In December 2014, a nurse named Nina Pham contracted Ebola from a patient in Dallas. She was transferred to the National Institutes of Health in Bethesda, Md., and treated by a team led by Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases.

When Ms. Pham was discharged, the cameras captured an indelible moment: Together with NIH Director Francis Collins, Dr. Fauci, dressed in a crisp white lab coat, walked her out with his arm draped over her shoulder. This conveyed a critical message at a time when public fear about the disease was widespread. “We would not be releasing Ms. Pham if we were not completely confident in the knowledge that she has fully recovered, is virus free and poses no public health threat,” an NIH statement read.

But scientific certainty often carries an asterisk. Six months later, doctors in Atlanta discovered that in some patients who survive, the Ebola virus could still be found hidden away in parts of the body. This did not indicate that they could transmit the disease, but it meant that they could no longer be declared “virus-free” with certainty. This episode demonstrated how quickly our knowledge about public health threats can alter. What we once thought was true for the Ebola virus had changed, and no doubt will continue to evolve.

Firms Develop Technology to Capture, Liquify, Transport, and Sequester CO2 into “Depleted Offshore Oil-and-Gas Wells”

(p. B4) ATHENS—Ship operators have a radical idea for industrial companies that are searching for ways to dispose of carbon emissions: Take the captured CO2 out to sea and bury it deep under the ocean floor.

But first, supercool the carbon emissions to temperatures so low that they become a liquid.

HD Hyundai Heavy Industries, the world’s largest shipyard, and Greece-based shipowner Capital Product Partners have designed a specialized vessel to carry liquefied CO2. They envision such ships transporting their cargo to depleted offshore oil-and-gas wells, where it would be pumped in and entombed for permanent storage. Capital Product Partners signed a deal for four such ships, to be delivered in 2025 and 2026, that together cost more than $300 million.

“Ships move everything from oil to our furniture, clothes and toothpaste. Now they’ll move our emissions, which is in effect waste management,” said Jerry Kalogiratos, chief executive of U.S.-listed Capital Product Partners, which operates more than 100 cargo vessels.

. . .

“The wells are sealed with a fast drying mix of concrete and sand. If there is a leak inland the gas could end up back in the atmosphere, but there is no conclusive research about what will happen if it escapes in the water,” said Fotis Pagoulatos, a naval engineer in Athens. “The consensus for now is that pollution risk at sea from leaked CO2 is low.”

. . .

While no contracts have been signed, Kalogiratos said Capital Product Partners is in talks with a number of European emitters as well as big energy companies in Japan and South Korea.
