phys.org:'One real mystery of quantum mechanics': Physicists devise new experiment
There has been a new experiment performed with simultaneously tested to see if a photon was a wave and a particle. And both sides of the experiment saw what it was expected to see. So a simultaneous measurement confirms that the photon is both a wave and a particle at the same time.

Is that a bead-like, or string-like particle? Directly visible with a powerful microscope? Or how?

Good article. I liked some of the comments with it.

No prizes for guessing why I liked:

"It is neither a wave nor a particle. A "particle" or a "wave" are the conceptual framework in which we conform reality, in order to observe it. The act of acquiring knowledge of reality, necessitates a conceptualization of it. We can not get out of our own intellectual way.Thus, the underlying reality,... 'unconceprualized reality' or 'reality as it is in itself',... should be understood as existing independent of the form in which we express it." smile

Bill S, are you a wave? Or a particle?

Me? On Mondays, I am a wave. On Tuesdays, the day I was born, I am a particle. laugh And so on! Any idea what TT is, and when? smile What about Ellis? And others?

I actually disliked that whole write up of the article a better write up was done by new scientist

http://www.newscientist.com/article/dn22...-weirdness.html

I loved the summation which was most apt

Quote:

The upshot of both experiments can be cast in the language of Schrödinger's cat. "Long after the cat has supposedly been killed or not, one can choose to determine if it is dead or alive or determine if it is dead and alive,"


Or in your language Rev I can decide tomorrow if I am a particle or wave today !!!!

Of coarse that leaves open the problem was I ever really either :-)

If you are struggling with that answer perhaps read the day earlier article than Bill's original post ... got to love QM

I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.

Quote:
From fundamental research to technical applications

In addition to the fundamental issue of the limits of macroscopic entanglement, the physicists address possibilities of potential applications. They are, for example, able to use the created photons for very precise angular measurements already at low intensities of light. This feature is of advantage in particular when investigating light sensitive materials, as for example some biological substances. "The special features of entanglement provide the fantastic possibility to perform such measurements from arbitrary distances and without any contact whatsoever with the measured object, or even at a point in time that lies in the future!" Fickler explains.


This quote is from Orac's link. Now that idea of measuring something that happens in the future is kind of scary. And he didn't even bring it to our attention until after Halloween.

Quantum tunnelling?

The Schröding-cat

Beware the quantum leap, my friend
With logic clear for all to see
Beware the Schröding-cat
And shun the dread uncertainty.

He took his double-slit in hand,
Long time the 'lusive truth he sought;
Then pondered he uncertainty,
And all the doubts it brought.

Then while in physic thought he stood,
The Schröding-cat with eyes aflame,
Came whiffling through the science lab
And bi-located as it came.

One two, one two, he measured true
Its locus in three-D,
But though he tried, it still did hide
Its real velocity.

Now you have found the Schröding-cat,
Open the box, that none may doubt
That quantum theory rules supreme…..
Oh, no; the bugger’s tunnelled out!

Good thoughts, Bill S! I am impressed.

Spooky !!!!!

But if you want really spooky look closely at those elecrons and how they behave (http://phys.org/news/2012-10-obstinate-electrons-assumptions-path.html)

BTW this is all very very topical at the moment more papers have been released and there are very solid proposals being framed for testing this stuff

These are worth reading :-)

Good luck and keep thinking and questioning !!!!

Some fascinating links there, Orac.

Either way, it would mean that the Universe is fundamentally nonlocal, in the sense that every bit of the Universe can be connected to any other bit anywhere, instantly.


Another step towards the Bill S. (crackpot) infinity treory. smile
