Elliptic Composability: June 2016
http://fmoldove.blogspot.com/2016_06_01_archive.html
Friday, June 24, 2016. Before jumping into the topic for today, let me say a few words about Brexit: UK put a show of monstrous selfishness and hypocrisy: after colonizing half the globe, now they complain about immigrants? Back to physics (and math). Last time I stated that geometry requires a generalization, so what does this all mean? There are many ways one can approach this, but let's do it in historical fashion and start with the duality:. And one example is operator non-commutativity in quantum me...

Sunday, November 20, 2016. It feels good to be back to physics, and as a side note going forward I will do the weekly posts on Sunday. Today I want to talk about Gleason's theorem. But what is Gleason's theorem? If you want to assign a non-negative real valued function (p(v) ) to every vector v of a Hilbert space H of dimension greater than two, then subject to some natural conditions the only possible choice is (p(v) = { langle v w rangle } {2} ) for all vectors v and an arbitrary but fixed vector w.

Elliptic Composability: March 2016
http://fmoldove.blogspot.com/2016_03_01_archive.html
Friday, March 25, 2016. Annealing and the D-Wave Quantum Computer. So what is annealing, and how does D-Wave use it to solve problems? The theory of light propagation in optical fibers is well know: from Maxwell's equations, in a certain appropriate approximation one obtains the so-called nonlinear Schrodinger equation. And numerical simulation methods are available to obtain the output given any input and any dispersion function. I wont't go in detail on what that problem is, and the strategies to go ar...

Elliptic Composability: November 2016
http://fmoldove.blogspot.com/2016_11_01_archive.html
Monday, November 28, 2016. Are Einstein's Boxes an argument for nonlocality? Today I want to discuss a topic from an excellent book by Jean Bricmont: Making Sense of Quantum Mechanics. Which presents the best arguments for the Bohmian interpretation. Although I do not agree with this approach I appreciate the clarity of the arguments and I want to present my counter argument. Frac{1}{ sqrt{2} ( B 1 rangle B 2 rangle) ). I say you will not get any interference because by weighing the boxes before releasin...

http://fmoldove.blogspot.com/2016/12/a-measurement-can-be-more-than-observer.html
Sunday, December 4, 2016. A measurement can be more than an observer learning the value of a physical observable. So last time he commented here: "A measurement is a process when an observer actually learns the value of a physical observable". Which from 10,000 feet is enough. However this is not precise enough, and now I do have a fundamental disagreement with Lubos which hopefully will put enough distance between him and me. If dropping the separator constitutes a measurement, the wavefunction would co...

Elliptic Composability: April 2016
http://fmoldove.blogspot.com/2016_04_01_archive.html
Friday, April 29, 2016. I was surprise by the interest in the last post, and I think a continuation of the topic using new material is in order. As side notes apparently I got upgraded on Lubos scale to "confused", so I hope I finally got past the misunderstanding that I am a closet admirer of classical physics which was really absurd since I am deriving quantum mechanics from physical principles. Currently I am reading Jean Bricmont's new book Making Sense of Quantum Mechanics. However, in the touching ...

Thursday, July 16, 2015. Joy Christian's program of achieving quantum correlations with Clifford algebras. In the last post I explained how the algebra of the projector operators cannot always. Be Boolean, otherwise the Hilbert space formalism of quantum mechanics is invalid. Today I will stay in the classical-quantum divide area and I'll talk about an invalid proposal. By Joy Christian which generated a lot of debate (and acrimony). When I attended the Vaxjo conference. A cdot b ). We use an identity:.

My favourite pedagogical principle: examples first! | Gowers's Weblog
https://gowers.wordpress.com/2007/10/19/my-favourite-pedagogical-principle-examples-first
Laquo; A paper on the ArXiV. My favourite pedagogical principle: examples first! If this too seems pretty obvious, I invite you to consider how common it is to do the opposite. Why should it be better to do it that way round? By now the alert reader will have noticed that I have not practised what I have preached. So let’s forget all about the discussion so far and start again, this time doing things properly. My favourite pedagogical principle: examples first! If we interpret and. Are fields. (If on...
