The Sokal Hoax: At Whom Are We Laughing?

The philosophical pronouncements of Bohr, Born, Heisenberg and Pauli deserve some of the blame for the excesses of the postmodernist critique of science.

by Mara Beller
At whom are we laughing? Derrida and Beller.

Newton spent much of his life on alchemy, trying to understand the bible's Book of Revelations, investing in and losing a fortune in the South Seas Bubble, and tracking down currency forgers for execution.

However, his Philosophiæ Naturalis Principia Mathematica contained non of this only the first foundations of calculus and physics.

As Newton noted in the preface of the 2nd edition: Hypotheses non fingo.
I have not as yet been able to discover the reason for these properties of gravity from phenomena, and I do not feign hypotheses. For whatever is not deduced from the phenomena must be called a hypothesis; and hypotheses, whether metaphysical or physical, or based on occult qualities, or mechanical, have no place in experimental philosophy [science]. In this philosophy particular propositions are inferred from the phenomena, and afterwards rendered general by induction.
Likewise, I've never read any philosophical pronouncements of Bohr, Born, Heisenberg, or Pauli. Well, until now. I have, however, read their physics papers that established the mathematical and physical foundations of quantum mechanics and quantum field theory: all math and physics, no philosophy

There is nothing obscure in the writings of Bohr's physics papers.

A collection of the English translations of the foundational papers

[Worth reading, if one has an interest in the field.]
Found it online:
A collection of the English translations of the foundational papers

Above my pay grade, but I'm in awe about the effort and genius applied by this A-Team to put the new puzzle together. Quick reading some first pages, one of them claimed in a quote that Bohr was not so much a physicist and more of a philosopher. :o

Interesting read:
Discussions with Einstein on Epistemological Problems in Atomic Physics
The difference is that Bohr et al. are the founders of quantum mechanics and quantum field theory, whereas Derrida makes it laughably clear that he has less than zero understanding of physics, willfully so, and is spouting purposely obscure postmodernist nonsense.

If he was anything other than a spunk artiste, he would have focused on understanding their physics papers and ignored their philosophical hobbies, if he was aware of them.
Indeed. Although the philosophies and possible other eccentricities of the founders of quantum mechanics do not take away anything of their ground breaking work, it is always interesting to know some more about it.

As opposed to post modernist Babylonia, they to where lucky enough to have a major Xtra partner during their journey of discovery that post-modernists thought could do without: nature. Somebody to consult, ask questions using experiment. A partner with at least 13.7 billion years of experience and equal knowledge base.

And it was not their fault that nature started to give sort of peek-a-boo answers in the quantum domain. Starting with Heisenb's uncertainty principle: "Will tell you where I am but never where I go. Will tell you where I go but never where I am" and all the way to probabilities of measurement where "what things are" between measurement/observation remains anyones poetic guess; although it being described mathematically works fine for all practical purposes like technology.

Maybe nature wants it to be that way. And it is kind of more sexy to keep the best stuff hidden somewhat.The nature of reality is certainly suggestive. A win-win. :)

The Marxists, as usual, are behind in their understanding.

This debate was settled, posthumously, by theory and subsequent experimental tests.

Bell's Theorem states that one will observe different results for QM and those of local hidden variable theories as favoured by Einstein (and ironically, Bell).

Ever more stringent experimental tests using Bell's Theorem have been performed and all have ruled out local hidden variables with every greater certainty.

Phys Rev | Event-Ready Bell Test Using Entangled Atoms Simultaneously Closing Detection and Locality Loopholes

All experimental evidence to-date indicates that the physical universe is a quantum mechanical one regardless of any philosophical objections.

The problem that many people have with QM is that there are no familiar analogies from our everyday experience.

I think 2^N is incorrect. This is what a binary bit does.

2^8=256 would be 8 bits for a conventional computer.

Maybe N^N is right, but I'm not sure.

8^8=16,777,216

Any clarification?

It has to do with the entanglement of the sub atomic particles.

There was an experiment that proved they behave differently when being measured to give you a more expected result.

The state of entanglement is the state of not being measured, this allows the SAP to act different.Not Be confined by our logic until the answer is produced.

Cern Courier | Birth of a Symmetry

SU(2) x U(1)
Weinberg’s paper “A Model of Leptons”, published in Physical Review Letters (PRL) on 20 November 1967, determined the direction of high-energy particle physics through the final decades of the 20th century. Just two and a half pages long, it is one of the most highly cited papers in the history of theoretical physics. Its contents are the core of the Standard Model of particles physics, now almost half a century old and still passing every experimental test.
As was the case with his comments in Brussels the previous month, Weinberg’s paper appeared in November 1967 to a deafening silence. “Rarely has so great an accomplishment been so widely ignored,” wrote Sidney Coleman in Science in 1979. Today, Weinberg’s paper has been cited more than 10,000 times. Having been cited but twice in the four years from 1967 to 1971, suddenly it became so important that researchers have cited it three times every week throughout half a century. There is no parallel for this in the history of particle physics.

I think that the point of the first highlighted poster comment is that the headline promised an explanation and the article in no way delivered one. Remember "Buzz words"? I always looked at them at a good way for people that do not understand a subject to try to look like they do.

You are probably correct.

Being incorrigibly lazy, I quickly scanned the quotes.

To understand quantum computing one should have a working knowledge of QM.
Well, to understand it at any meaningful level.

I have not payed much attention to the field as the gap between what is predicted by theory and what has actually been built to date is rather large.
There is always the possibility of a major breakthrough, but decoherence is a challenging obstacle.

You can take a 16 qubit processor at the IBM Quantum Experience (QX) for a spin*.

Forbes - Spiegel | Merging Neutron Stars Seen With Both Gravitational Waves And Light

Science | Merging neutron stars generate gravitational waves and a celestial light show
Four times in the past two years, physicists working with mammoth gravitational wave detectors have sensed something go bump in the night, sending invisible ripples through spacetime. Today, they announced the detection of a fifth such disturbance—but this time astronomers saw it too, at every wavelength of light from gamma radiation to radio waves. Just as physicists had predicted, the unprecedented view of the cosmic cataclysm—in which two super-dense neutron stars spiraled into each other—brought with it a cornucopia of insights, each of which by itself would count as a major scientific advance.

Science Mag | New test of electron’s roundness could help explain universe’s matter/antimatter imbalance
When it comes to measuring how round the electron is, physicists hate uncertainty. Much depends on the most precise measurement possible, including a potential answer to a major scientific puzzle: why the universe contains any matter at all.

In a series of ever-more-sensitive experiments over the past 30 years, researchers have established that if the shape of the electron has any distortion at all, the bulge must be smaller than 1 thousand trillion trillionths of a millimeter (10-27 mm). Now, a group at the JILA research institute in Boulder, Colorado, has demonstrated what it describes as a "radically different" approach that probes electrons inside larger charged particles. Ed Hinds of Imperial College London calls the approach "brilliant" for the field, because it promises to help reduce the uncertainty still further—and perhaps reveal an actual distortion.

Any mention of the error margin of this "measurement?"

Obviously, there must be a tolerance on the length of the millimeter used in comparison. Africa millimeter or European millimeter?

Is this minute dimension measured on an electron that is at room temperature? Was the thermometer calibrated?

While I appreciate the efforts of those on the cutting edge, doing work I could never do, I always find it interesting when cutting edge science gets either magical or religious.

The experimental uncertainties, statistical + systematic, are summarized in the Wikiped section below.

As these are controlled experiments, rather than observations [such as global temperature deviations], they are repeatable and reproducible.
Most of the analysis effort goes into understanding any and all possible sources of systematic error.

That's the fascinating part, IMSMO, for the non-cognoscenti, it sounds like two priests arguing over whether 400 or 500 angels can dance on the head of a pin. Fat angels or skinny angels? Catholic or Protestant priests?

I'm glad there are people who can spend decades engaged in fields of study that are inches wide and miles deep, because one can never imagine the future value of such a knowledge base. But for those of us who are a couple feet wide and 18" deep....... it is like listening to Coast2CoastAM. Fun stuff, but not as important as keeping the lights on or automobile brakes from failing.

In the 19th century, many would have argued that keeping one's horse healthy and well shod was far more important than Faraday's toy experiments and Maxwell's theories. Yet electromagnetism is today one of the foundations of our industrial civilization.

The same could have been said about the obscure early 20th puzzles regarding atomic spectra and black body radiation. The explanation, quantum mechanics, is now part of our everyday lives: transistors, lasers, LEDs, and, if necessary, MRIs. Another foundation of our industrial civilization.

Also in the early 20th, pondering the nature of space, time, and mass lead to general relativity, a theory which also seems at first completely removed from daily life, yet is required to operate the global positioning system - the GPS, which has become an essential part of air and sea navigation along with personal use and much anticipated autonomous vehicles.

Asking the modern version of "how many angels can fit on the head of a pin?", "how many transistors can fit on the head of a pin?', lead to VLSI and multibillion transistor CPUs and GPUs.

Thanks to EM and QM you can listen to Coast2CoastAM streaming over the internet.

Science is the spanner in the works of men and women who see them as sensible, sound, and practical minded or, less charitably, lacking in imagination and the ability to think long term*. Given that science is unpredictable, discoveries are driven by curiosity, and are often serendipitous. it is also the bane of contemporary management theory and methods. I don't know if the measurements above will find some practical applications, but am confident that the techniques developed to perform them will.

*When William Gladstone, then British Chancellor of the Exchequer (Minister of Finance) later PM, asked Faraday, after one of his demonstrations, of the practical value of electricity (1850), apocrypha has it that Faraday replied,
"Why, Sir, there is every probability that you will soon be able to tax it."

Before the LHC at CERN, the most powerful particle accelerator on the planet was the Tevatron at Fermilab, located in the far west suburbs of Chicago [Batavia, IL]. During US Congress hearings on its construction, a member of Congress asked the Director, Robert Wilson, if building the Tevatron would contribute to national security. This was during the height of the Cold War. Rather than providing historical justifications, as I've done above, Wilson was far more direct, "No, but it one of the things that makes the US worth defending." Of course, he was not referring to the Tevatron itself, but to the culture and civilization willing to undertake such a project.

Well said as always. Celebrate diversity!

You do the ground work which makes my future teleportation and contact with ET possible, and I'll keep the lights on in your lab and the brakes working in your car so you can drive thru the war zones of Chicago without fear. ;)

Deal?

Now, can you create a death ray we can use to purge "science" of those pesky "climate scientists?" They are destroying your brand and credibility! If not soon, let me know, we have plenty of old school weapons in stock..... maybe stockades or dunking chairs until they recant? :P

In the 19th century, many would have argued that keeping one's horse healthy and well shod was far more important than Faraday's toy experiments and Maxwell's theories. Yet electromagnetism is today one of the foundations of our industrial civilization.

The same could have been said about the obscure early 20th puzzles regarding atomic spectra and black body radiation. The explanation, quantum mechanics, is now part of our everyday lives: transistors, lasers, LEDs, and, if necessary, MRIs. Another foundation of our industrial civilization.

Also in the early 20th, pondering the nature of space, time, and mass lead to general relativity, a theory which also seems at first completely removed from daily life, yet is required to operate the global positioning system - the GPS, which has become an essential part of air and sea navigation along with personal use and much anticipated autonomous vehicles.

Asking the modern version of "how many angels can fit on the head of a pin?", "how many transistors can fit on the head of a pin?', lead to VLSI and multibillion transistor CPUs and GPUs.

Thanks to EM and QM you can listen to Coast2CoastAM streaming over the internet.

Science is the spanner in the works of men and women who see them as sensible, sound, and practical minded or, less charitably, lacking in imagination and the ability to think long term*. Given that science is unpredictable, discoveries are driven by curiosity, and are often serendipitous. it is also the bane of contemporary management theory and methods. I don't know if the measurements above will find some practical applications, but am confident that the techniques developed to perform them will.

*When William Gladstone, then British Chancellor of the Exchequer (Minister of Finance) later PM, asked Faraday, after one of his demonstrations, of the practical value of electricity (1850), apocrypha has it that Faraday replied,
"Why, Sir, there is every probability that you will soon be able to tax it."

Before the LHC at CERN, the most powerful particle accelerator on the planet was the Tevatron at Fermilab, located in the far west suburbs of Chicago [Batavia, IL]. During US Congress hearings on its construction, a member of Congress asked the Director, Robert Wilson, if building the Tevatron would contribute to national security. This was during the height of the Cold War. Rather than providing historical justifications, as I've done above, Wilson was far more direct, "No, but it one of the things that makes the US worth defending." Of course, he was not referring to the Tevatron itself, but to the culture and civilization willing to undertake such a project.
Well said as always. Celebrate diversity!

Sure. ;)

Unfortunately, this year will be the first in over a decade that I will not be making my annual post-Thanksgiving trip to Chicagoland
as the goals of my work have changed. Already missing it. Hope to return in a year or two.

Science has grown rapidly due to its success over the last four centuries. As with any human activity, over time rot occurs in the form of opportunists and scoundrels. The unsupported over-the-top claims of some climate scientists are probably the worst example of junk science in the history of science, with eugenics coming a close second. Hopefully, this to will pass, although I suspect that the "Because science" crowd who treat science as a secular religion and scientists as pseudo-religious authority figures will simply move onto the next imminent, yet ever receding, apocalypse aided and abetted by a new generation of former B students.

Yep. Never doubt the appeal and influence of free money and doomer porn. Already the global warming experts of today are denying the existence of the global cooling experts of the 1970's.

Science as an institution will survive simply because it works. The short term (human generation or two) ripples will be interesting to watch. They should be localized. Some denominations will suffer more than others. Pedophilia in the Catholic Church is a good analogy.

Unfortunately, due to political funding of both, Climate Change is being taught to grade schoolers as Gospel in US public schools. It will be sad to see so many bright kids in the US get steered down a mythical path. I know more than a few fathers who are engineers who are correcting the party line as it is taught to their children in real time.

But, hopefully by employing scientific discipline, they students themselves will self-correct in spite of what their professors teach them.

Thankfully, physics ain't feelings.

Quark-level analogue of nuclear fusion with doubly heavy baryons

Who knows, perhaps one day particles only created on earth in high energy particle accelerators will power fusion.

Although, we probably need to get the regular version going first ;)

Another quantum spindoctor making claims he can't support with evidence and just self-contracts everything he is saying. At least in the MMGW community of scientists one can expect a number of them willfully lie to preserve their own career, here it seems people are deluded and delude honestly not being aware of it.

Just be glad there is no cryptocoin ico based on a quantum blockchain.

I read and reread the abstract three times and I still have no clue as to what it is trying to say.
