Reverse salients | West Hunter
Edison thought in terms of reverse salients and critical problems.

“Reverse salients are areas of research and development that are lagging in some obvious way behind the general line of advance. Critical problems are the research questions, cast in terms of the concrete particulars of currently available knowledge and technique and of specific exemplars or models that are solvable and whose solutions would eliminate the reverse salients. ”

What strikes you as as important current example of a reverse salient, and the associated critical problem or problems?

Why read old philosophy? | Meteuphoric
(This story would suggest that in physics students are maybe missing out on learning the styles of thought that produce progress in physics. My guess is that instead they learn them in grad school when they are doing research themselves, by emulating their supervisors, and that the helpfulness of this might partially explain why Nobel prizewinner advisors beget Nobel prizewinner students.)

The story I hear about philosophy—and I actually don’t know how much it is true—is that as bits of philosophy come to have any methodological tools other than ‘think about it’, they break off and become their own sciences. So this would explain philosophy’s lone status in studying old thinkers rather than impersonal methods—philosophy is the lone ur-discipline without impersonal methods but thinking.

This suggests a research project: try summarizing what Aristotle is doing rather than Aristotle’s views. Then write a nice short textbook about it.

Uniformitarianism - Wikipedia
Uniformitarianism, also known as the Doctrine of Uniformity,[1] is the assumption that the same natural laws and processes that operate in the universe now have always operated in the universe in the past and apply everywhere.[2][3] It refers to invariance in the principles underpinning science, such as the constancy of causality, or causation, throughout time,[4] but it has also been used to describe invariance of physical laws through time and space.[5] Though an unprovable postulate that cannot be verified using the scientific method, uniformitarianism has been a key first principle of virtually all fields of science.[6]

In geology, uniformitarianism has included the gradualistic concept that "the present is the key to the past" (that events occur at the same rate now as they have always done); many geologists now, however, no longer hold to a strict theory of gradualism.[7] Coined by William Whewell, the word was proposed in contrast to catastrophism[8] by British naturalists in the late 18th century, starting with the work of the geologist James Hutton. Hutton's work was later refined by scientist John Playfair and popularised by geologist Charles Lyell's Principles of Geology in 1830.[9] Today, Earth's history is considered to have been a slow, gradual process, punctuated by occasional natural catastrophic events.

Lynn Margulis | West Hunter
Margulis went on to theorize that symbiotic relationships between organisms are the dominant driving force of evolution. There certainly are important examples of this: as far as I know, every complex organism that digests cellulose manages it thru a symbiosis with various prokaryotes. Many organisms with a restricted diet have symbiotic bacteria that provide essential nutrients – aphids, for example. Tall fescue, a popular turf grass on golf courses, carries an endosymbiotic fungus. And so on, and on on.

She went on to oppose neodarwinism, particularly rejecting inter-organismal competition (and population genetics itself). From Wiki: [ She also believed that proponents of the standard theory “wallow in their zoological, capitalistic, competitive, cost-benefit interpretation of Darwin – having mistaken him… Neo-Darwinism, which insists on [the slow accrual of mutations by gene-level natural selection], is in a complete funk.”[8] ‘


You might think that Lynn Margulis is an example of someone that could think outside the box because she’d never even been able to find it in the first place – but that’s more true of autistic types [like Dirac or Turing], which I doubt she was in any way. I’d say that some traditional prejudices [dislike of capitalism and individual competition], combined with the sort of general looniness that leaves one open to unconventional ideas, drove her in a direction that bore fruit, more or less by coincidence. A successful creative scientist does not have to be right about everything, or indeed about much of anything: they need to contribute at least one new, true, and interesting thing.
“A successful creative scientist does not have to be right about everything, or indeed about much of anything: they need to contribute at least one new, true, and interesting thing.” Yes – it’s like old bands. As long as they have just one song in heavy rotation on the classic rock stations, they can tour endlessly – it doesn’t matter that they have only one or even no original members performing. A scientific example of this phenomena is Kary Mullins. He’ll always have PCR, even if a glowing raccoon did greet him with the words, “Good evening, Doctor.”

jet fuel can't melt steel beams:
You have to understand a subject extremely well to make arguments why something couldn’t have happened. The easiest cases involve some purported explanation violating a conservation law of physics: that wasn’t the case here.

Do I think you’re a hotshot, deeply knowledgeable about structural engineering, properties of materials, using computer models, etc? A priori, pretty unlikely. What are the odds that you know as much simple mechanics as I do? a priori, still pretty unlikely. Most likely, you’re talking through your hat.

Next, the conspiracy itself is unlikely: quite a few people would be involved – unlikely that none of them would talk. It’s not that easy to find people that would go along with such a thing, believe it or not. The Communists were pretty good at conspiracy, but people defected, people talked: not just Whittaker Chambers, not just Igor Gouzenko.

[1509.02504] Electric charge in hyperbolic motion: The early history and other geometrical aspects
We revisit the early work of Minkowski and Sommerfeld concerning hyperbolic motion, and we describe some geometrical aspects of the electrodynamic interaction. We discuss the advantages of a time symmetric formulation in which the material points are replaced by infinitesimal length elements.

SPACE AND TIME: An annotated, illustrated edition of Hermann Minkowski's revolutionary essay:
