Can the Quantum Realm Explain Reality?

If we can uncover the smallest quantum particles in nature, will we have uncovered the fundamental secrets of reality?

If we can uncover the smallest quantum particles in nature, will we have uncovered the fundamental secrets of reality? A longstanding philosophical tradition in the sciences claims “yes.” Uncovering the mystery of the world lies in the ability to interrogate the smallest of the small. But is that the right way to approach it? What special status does the tiny have over the large? A paper at IAI News by London philosopher Peter West argues that reality can’t in fact be elucidated simply by observing quantum mechanics. He talks in some length about the 17th century text Micrographia by Robert Hooke, which features various images of insects and other organisms under the microscope. West notes that Hooke set the stage, Read More ›

Science After Babel

Read an excerpt of a new book by mathematician and philosopher David Berlinski

By David Berlinski Editor’s note: We are delighted to welcome Science After Babel, the latest book from mathematician and philosopher David Berlinski. This article is adapted from the book’s Introduction. The scientific revolution began in the 16th century, and it began in Europe. No one knows why it happened nor why it happened where it happened, but when it happened, everything changed.  Until the day before yesterday, the imperial architects of the scientific revolution were well satisfied and sleek as seals. An immense tower was going up before their very eyes. The physicists imagined that shortly it would reach the sky; the biologists were satisfied that it had left the ground; and only the theologians were heard to observe that it Read More ›

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 Read More ›

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 Read More ›

Quantum Physicist Julie Love to Speak at COSM 2021

She fell in love with physics in high school, and continues to pursue that love today at Microsoft

She may not be a household name, but Dr. Julie Love works with technology that could have massive implications on our economy, in our industry and agriculture, and on society at large: Quantum computing. At this year’s COSM conference in Bellevue, Washington, Love will be addressing quantum computing and the question, “Does it change everything, or anything?” First, what exactly is quantum computing? “Quantum computing applies the properties of quantum physics to the processing of information,” Love explains in a Youtube series produced by Microsoft exploring the impact of the technology. “This exponentially faster and more powerful computing will accelerate the development of new sustainable materials, improved healthcare, methods to address food production, and combat climate change.” You can watch Read More ›

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 Read More ›

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 Read More ›

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 Read More ›

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 Read More ›

Can Quantum Mechanics Help Decipher Consciousness? Free Will?

Nobel laureate Roger Penrose, among others, looked to the quantum world for models

In Walter Bradley Center director Robert J. Marks’s second podcast with philosopher Angus Menuge, the big topic is the perennial “Hard Problem of consciousness and various proposed solutions. One of the questions that often comes up is quantum consciousness. Earlier, they had discussed Integrated Information Theory (IIT) and panpsychism.

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 Read More ›

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 Read More ›

A Materialist Gives Up on Determinism

Evolutionary biologist Jerry Coyne undercuts his own argument against free will by admitting that quantum phenomena are real

Evolutionary biologist Jerry Coyne has denied free will for years. But most recently, he has said something that puts the whole matter in doubt. A bit of background: Free will simply cannot be real if determinism is true, that is, if everything in nature falls like dominoes after the first one is pushed: If nature is truly like that, our acts, like those of the dominoes, are wholly determined by natural history and physical laws that we do not control. Nearly all arguments against free will depend critically on determinism. But there is a central problem with determinism: It is clear from physics that determinism in nature is not true. In 1964, theoretical physicist John Bell (1928–1990) proposed relatively simple Read More ›
