“Quantum Nonsense” at the Chicago Skeptics

Posted by mattusmaximus on May 2, 2015

On April 18th I gave a presentation to the Chicago Skeptics on the topic of what I call Quantum Nonsense. For example, have you ever been talking to a friend who starts going on about how great a movie “What the Bleep?!” was because it proved water has feelings? Or perhaps a family member saw a show where Deepak Chopra explained that they could balance their checkbook and achieve financial security using quantum jumping? Let’s face it, quantum physics is both fascinating and confusing, and many pseudoscientists and charlatans play upon this fascination and confusion to peddle all manner of nonsense to the unwary. In this talk I try to help people learn how to separate quantum fact from fiction.

Download the PowerPoint of the presentation (one with the audio of the talk embedded) below. If you want to be able to flip through the slides, which I recommend since there are many good visuals, I suggest downloading both files and listening to the audio while flipping through the other presentation. Enjoy! 🙂

Testing String Theory? How Real Science Progresses

Posted by mattusmaximus on September 16, 2010

Something very interesting has happened recently in the world of theoretical physics.  One of the hottest ideas around is the notion of so-called string theory: it’s the idea that all matter & energy in the universe – from the electrons & quarks that make up atoms to photons of light to everything in between – is composed of ultra-tiny strings of vibrating energy.  It’s a marvelous and mathematically elegant idea, one which many theoretical physicists believe holds the key to unifying the fundamental forces of nature, but it suffers from a big flaw: these strings are, according to the theory, so small that we have no way to experimentally detect them. Thus, if such is the case, then many physicists & critics of string theory have equated the idea with a dragon in the garage, an unfalsifiable notion which isn’t subject to scientific investigation.  I have placed myself into this category of string theory skeptics for quite a long time for this very reason…

… up until now, that is.  It seems that the question of whether or not string theory is testable, and therefore real science, has been answered.  That’s because recent theoretical analysis of string theory has revealed that it makes unique predictions which can be tested in a controlled laboratory setting having to do with a weird phenomenon called quantum entanglement. Up until now, physicists haven’t had a good way to really predict the behavior of systems that coupled via quantum entanglement, but it seems that some aspects of string theory can shed some light on this…

New study suggests researchers can now test the ‘theory of everything’

String theory was originally developed to describe the fundamental particles and forces that make up our universe. The new research, led by a team from Imperial College London, describes the unexpected discovery that string theory also seems to predict the behaviour of entangled quantum particles. As this prediction can be tested in the laboratory, researchers can now test string theory.

Over the last 25 years, string theory has become physicists’ favourite contender for the ‘theory of everything’, reconciling what we know about the incredibly small from particle physics with our understanding of the very large from our studies of . Using the theory to predict how entangled quantum particles behave provides the first opportunity to test string theory by experiment.

“If experiments prove that our predictions about quantum entanglement are correct, this will demonstrate that string theory ‘works’ to predict the behaviour of entangled quantum systems,” said Professor Mike Duff FRS, lead author of the study from the Department of Theoretical Physics at Imperial College London.

“This will not be proof that string theory is the right ‘theory of everything’ that is being sought by cosmologists and particle physicists. However, it will be very important to theoreticians because it will demonstrate whether or not string theory works, even if its application is in an unexpected and unrelated area of physics,” added Professor Duff. …

Live Blog of CFI Chicago’s “Dangerous Nonsense” – Entry #2

Posted by mattusmaximus on April 24, 2010

Speaker #2: Dr. Michael Albrow , physicist at FermiLab, talking about “What’s True and What’s Untrue in Physics Today?”

Opening joke: please take away from this that physics is much simpler than biology! 🙂

Some knowledge is as certain as certain can be, while some things are necessarily uncertain.  There is much we know is not possible, but there is much which we know is also outside of our domain.

The beginning of modern science probably started with Galileo and his conflict with the Church.  Differences between science & religion…


*distrust authority / only Nature is authority

*criticism encouraged

*all hypotheses are testable by repeatable experiments / observations

*try to fault existing theories, make progress

*theory = explanation

*disagreements are healthy

*accepted standards of statistics & evidence



*questioning / criticism not encouraged

*not fundamentally upheld to testing

*”theory” = speculation

*disagreements discouraged / when scientists disagree that mans they’re wrong

*poor understanding or misuse of statistics & numbers

Deepak Chopra Goes Off the Deep End of the Woo-Pool

Posted by mattusmaximus on January 3, 2010

One of the kings of New Age nonsense, Deepak Chopra, has written a widely read article at the Huffington Post (yet another reason to no longer take HuffPo seriously), and I felt that it deserved a bit of analysis.  The piece, titled Woo Woo Is a Step Ahead of (Bad) Science, is an interesting rant on the part of Chopra about why all things about the modern skeptical movement, “western” science (science is science folks, wherever it’s practiced), and Michael Shermer are off base, wrong, and just plain mean & nasty.  Chopra really seems to have had something stuck in his craw, and I suppose this was his way of getting it out…

There’s plenty of silliness to cover in Chopra’s article, so we might as well get started…

The Large Hadron Collider – Where Does Science End & Pseudoscience Begin?

Posted by mattusmaximus on October 20, 2009

Where does legitimate science end and questionable pseudoscience begin?  It’s a good question, and one brought up in my mind due to a story about the theory behind the Large Hadron Collider (LHC) which has gotten a lot of attention in recent days.  Two theoretical physicists have come up with a theory by which they propose to explain why the LHC might never detect particles like the Higgs Boson… sabotage from the future.

Yes, you read that right – sabotage from the future. I’ll let the article explain it a bit more…

The Collider, the Particle and a Theory About Fate

Then it will be time to test one of the most bizarre and revolutionary theories in science. I’m not talking about extra dimensions of space-time, dark matter or even black holes that eat the Earth. No, I’m talking about the notion that the troubled collider is being sabotaged by its own future. A pair of otherwise distinguished physicists have suggested that the hypothesized Higgs boson, which physicists hope to produce with the collider, might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather.

Holger Bech Nielsen, of the Niels Bohr Institute in Copenhagen, and Masao Ninomiya of the Yukawa Institute for Theoretical Physics in Kyoto, Japan, put this idea forward in a series of papers with titles like “Test of Effect From Future in Large Hadron Collider: a Proposal” and “Search for Future Influence From LHC,” posted on the physics Web site in the last year and a half.
