Theoretical Physicist: Quantum Theory Must Be Replaced

Impatient with the results of recent experiments, she seeks a better theory that is not observer-dependent

Recently, we ran a piece featuring the views of well-known science writer John Horgan who talked about a truly strange element of quantum physics confirmed by recent experiments — that it seems as if there is no knowledge apart from observers’ minds. Theoretical physicist Sabine Hossenfelder is decidedly unhappy with that approach: Physicists have shown that objective reality doesn’t exist. This is allegedly an insight derived from quantum mechanics. And not only this, it’s been experimentally confirmed. Really? How do you prove that reality doesn’t exist? Has it really been done? And do we have to stop saying “really” now? That’s what we’ll talk about today. Many of you’ve asked me to comment on those headlines claiming that reality doesn’t…

What If Quantum Physics Were Applied To Economics?

A mathematician argues that ideas that seemed bizarre in classical physics makes perfect sense in economics

Applied mathematician David Orrell offers a look at the difference quantum mechanical thinking would make to economics. The author of Money, Magic, and How to Dismantle a Financial Bomb: Quantum Economics for the Real World (2022) received considerable criticism for an article he wrote four years ago, “Economics is quantum,” which he summarizes in a followup article, published this month: The idea is that money is best understood as a quantum social technology, with quantum properties of its own. In financial transactions, for example, value can be modelled as a probabilistic wave function which ‘collapses’ down to an exact number when money is exchanged. When you put your house up for sale, you might have a fuzzy idea of its…

Seth Lloyd Will Take Us Into the Quantum Realm at COSM 2021

Dr. Lloyd, an MIT physicist, will tackle "Quantum Computing: Does it Change Everything, or Anything?"

Quantum physics has captured the imagination of culture, despite the fact that it upends everyday physics. Take, for instance, Marvel’s Ant Man (2015), whose creators consulted with physicists in their seemingly-absurd application of quantum physics to a fictional superhero universe. Quantum science will be one of the many topics explored at COSM 2021 this November. To aid in that exploration, physicist Seth Lloyd will be joining to discuss, “Quantum Computing: Does it Change Everything, or Anything?” Dr. Lloyd earned his Ph.D. from Rockefeller University, and is currently a professor of mechanical engineering at MIT. His research interests lie in quantum information and control theory. He has authored and co-authored over 200 scientific publications, and is the author of Programming the…

Is a Science Writer’s “Agnosticism” a Futile Pursuit?

John Horgan, a creative thinker and able writer, is agnostic about quantum mechanics, consciousness, and God. But let’s look at the bases for that.

If science writer John Horgan had merely said that agnosticism is the only sensible stance regarding God, there would be little surprise. That view is over-represented in popular science writing. But he says the same thing about quantum mechanics and consciousness too. Some brief snippets from his article (with brief responses): He’s not happy that quantum mechanics, a well-established branch of science (our computers would not work if it were not real) cannot eliminate the role of the conscious observer: Quantum mechanics Introducing consciousness into physics undermines its claim to objectivity. Moreover, as far as we know, consciousness arises only in certain organisms that have existed for a brief period here on Earth. So how can quantum mechanics, if it’s…

Quantum Theory of Consciousness Gains Support From Recent Study

The researchers were testing principles that underpin the Penrose–Hameroff theory

Cristiane de Morais Smith, a condensed matter physicist at the University of Utrecht in Belgium, has teamed up with colleagues from China led by quantum physicist Xian-Min Jin at Shanghai Jiaotong University to test principles that underpin a quantum theory of consciousness. Many dismiss the idea, originally proposed in the Nineties by Roger Penrose and Stuart Hameroff, because it is assumed that quantum mechanical laws (as opposed to classical physics laws) apply mainly at very low temperatures, for example at – 272 C, which is just below – 273 (absolute zero, when all classical movement stops). De Morais Smith and Xian-Min think, however, that they may have come a bit closer to validating the idea: Our brains are composed of…

Quantum Physics: Is Everything Determined? Egnor vs. Papineau

Physicalist philosopher David Papineau is clearly unhappy with the implications of quantum mechanics, as neurosurgeon Michael Egnor sets them out

Yesterday, we published the fifth portion of the debate between materialist philosopher David Papineau and neurosurgeon Michael Egnor, where the key issue was “Can traditional philosophy help us understand the mind vs. the brain?” In this final instalment, we look at the portion which starts roughly at 47 min where Papineau and Egnor start to talk about quantum physics, the physics that governs electrons, which famously do not obey the same rules as larger particles and are also the most basic level of the brain (partial transcript): Note: Dr. Papineau is a “physicalist.” On that view, “the mind is a purely physical construct, and will eventually be explained entirely by physical theory, as it continues to evolve.” (Philosophy basics) He…

Can Traditional Philosophy Help Us Understand Mind vs. Brain?

Michael Egnor asks us to look back to the traditional idea that the soul is the “form” of the body

Yesterday, we published the fourth portion of the debate between materialist philosopher David Papineau and neurosurgeon Michael Egnor, where the key issue was “Is the mind simply what the brain does?” Today, we look at the portion which starts roughly at 36 min where Papineau and Egnor start to talk about traditional philosophical ways of thinking about the soul and the body (partial transcript): Note: Dr. Papineau is a “physicalist.” On that view, “the mind is a purely physical construct, and will eventually be explained entirely by physical theory, as it continues to evolve.” (Philosophy basics) He is considered to be one of the best defenders of naturalism (nature is all there is), often called “materialism.” Michael Egnor: In the…

Can a Materialist Consciousness Theory Survive Quantum Mechanics?

Quantum mechanics requires that the observer be part of the measurement; thus quantum measurements must include consciousness

In Walter Bradley Center director Robert J. Marks’s second podcast with philosopher Angus Menuge, where the big topic is the perennial “Hard Problem of consciousness, one of the questions was whether quantum mechanics can help decipher consciousness. But that leads to another question: Can any materialist view of consciousness survive quantum mechanics? https://episodes.castos.com/mindmatters/Mind-Matters-134-Angus-Menuge.mp3 This portion begins at 22:35 min. A partial transcript, Show Notes, and Additional Resources follow. Robert J. Marks: Is quantum consciousness rooted in materialism? Can you look at quantum consciousness and say, this is materialistic? Angus Menuge: That’s a tricky question. For most materialists, their paradigm is really set by older 19th-century views of physical science. By definition, this goes beyond that. However, if one defines materialism…

Why Do Some Famous Materialist Scientists Hate Philosophy?

Philosopher of biology Massimo Pigliucci takes Richard Dawkins to task for dismissing philosophy but he might have said the same of Stephen Hawking

Massimo Pigliucci (pictured) makes clear that he is a naturalist (materialist) like zoologist Richard Dawkins. For example, he tells us that they crossed paths at a conference whose purpose was to promote naturalism (materialism): Over four centuries of scientific progress have convinced most professional philosophers and scientists of the validity of naturalism: the view that there is only one realm of existence, the natural world, whose behavior can be studied through reason and empirical investigation. The basic operating principles of the natural world appear to be impersonal and inviolable; microscopic constituents of inanimate matter obeying the laws of physics fit together in complex structures to form intelligent, emotive, conscious human beings.

Trying To Disprove Free Will Shows That Materialism Doesn’t Work

If you have a metaphysical theory and it contradicts science, logic, and everyday experience, then your metaphysics should be abandoned

Biologist Jerry Coyne, who is also an atheist activist, offers another post denying free will. Journalist Oliver Burkeman published an essay at the The Guardian last week, asking, “The clockwork universe: is free will an illusion?”, quoting Coyne among others. Coyne, who believes that free will is indeed an illusion, offers support at his blog. Read at your leisure but note: He ignores critical science issues around free will, including the following: 1. Nature is not deterministic. The fact that nature is not predetermined in detail has been shown quite convincingly by the experimental confirmation of Bell’s theorem in quantum mechanics. Succinctly, over the past 50 years, at least 17 teams of researchers have asked and answered the question: does…

Could the World Above the Level of the Particle Be Superposed?

It’s been done with molecules. After that, there are barriers

In last week’s podcast,,” our guest host, neurosurgeon Michael Egnor, interviewed idealist philosopher of science and physicistBruce Gordon on how the quantum physics that underlies our universe makes much more sense if we have a non-materialist view of reality. Even then, it challenges our conventional view of how nature “must” work: We were introduced to the quantum eraser experiment, which showed that what happens at the level of individual particles depends on whether you choose to measure it or not and to non-locality, the Cheshire Cat’s science of being in no one particular place at any time. Particles can do that even if we can’t. But wait: Is it possible that things larger than particles can in fact do that…

The World’s First Quantum Chess Tournament Announces a Winner

Quantum chess allows for superposition, entanglement, and interference

Perimeter Institute’s Aleksander Kubica won: So what’s quantum chess? It’s a complicated version of regular chess that incorporates the quantum concepts of superposition, entanglement, and interference. “It’s like you’re playing in a multiverse but the different boards [in different universes] are connected to each other,” said Caltech physicist Spiros Michalakis during a livestream of the tournament. “It makes 3D chess from Star Trek look silly.” Jennifer Ouellette, “We have a winner in the world’s first quantum chess tournament” at Ars Technica Okay: Superposition: Elementary particles of our universe are not in one single specific place, they are only in a probable one.

Could Slowing Quantum Processes Lead To More Useful Computing?

“Adiabatic” quantum computing slows down the process, in the hope of achieving more reliable quantum positions

In a recent podcast, “Enrique Blair on quantum computing,” Walter Bradley Center director Robert J. Marks talks with fellow computer engineer Enrique Blair about why quantum mechanics is so strange but important to our future. They discussed the prospects of slowing down quantum computing to make it more useful (adiabatic computing). https://episodes.castos.com/mindmatters/Mind-Matters-110-Enrique-Blair.mp3 The discussion of quantum communication begins at approximately 58:47. The Show Notes and transcript follow. Enrique Blair (pictured): I guess the challenge with entangling massive numbers of quantum systems is that entanglement becomes much more fragile. In quantum communication, you just need pairs of photons to be entangled. One with another, that’s it. Whereas with quantum computing, you need many, many systems to be entangled, and that’s just…
