The video “Why Quantum Mechanics is Weird” (25k views) won the 2005 Berkeley Video&Film Festival Best of Festival Award in Education. That is second place, behind a Grand Festival Award which went to a film on polar bears (much cuter than me talking for 27 minutes). In this blog, I will go through the math behind the video which provides a novel, entirely mathematical explanation for why causality is different between classical and quantum mechanics. Calculus done correctly in spacetime may turn out to provide the correct answer, completely philosophy-free, as it must be.

Why does local realism being wrong imply that non-local reality is true? Such is widely opined to be the only sober solution because it conserves good old reality, the scientists’ fort that is to be defended against the onslaught of magic.

However, reality with “spooky actions at a distance” is not non-magical either. Nevertheless, the issue is known as “non-locality in quantum physics”, never as “non-reality in quantum physics”. How about keeping localism and instead accepting that realism is a god of the gaps in retreat? Don’t like it? Well, how about at least not being so sure about it for starters?

Let us try to model the experiment described in “Disproving Local Realism” with help of tennis balls. 800 pairs of tennis balls are each prepared, say some instructions are written on them, and then split. One ball is always thrown to Alice on the left; the second flies to Bob on the right.

Every of the 800 trials starts with the preparation of a pair. When the left going ball is about half way to Alice, Alice randomly rotates a setup, called her “crystal”, either so that it is at an “angle” a=0 or a=1.

What if what we thought, and held most dear, about the fundamentals of physical science was wrong? That atoms and quantum particles were not what we believed them to be. That planets, star systems and the Universe itself had a far more intrinsic correlation to the material structure that fundamentally constituted those systems. What if our most cutting edge mainstream theoretical theories were completely off track? What if? This is what my own research in science has lead me to strongly question and it has been an interesting journey.

Since Science 2.0 first came online, we have been excited about the Tevatron in Illinois because, statistically, by 2011 the famous Fermi experiment in Batavia,IL would have accumulated 10 inverse femtobarns of data and that means the Higgs, if it exists, would be somewhere in there.  If it could be found.
Amelia Fraser-McKelvie  is not a career researcher or a post-doctoral fellow or even in graduate school, but working on a summer scholarship at the Monash School of Physics, she conducted a targeted X-ray search for the matter called the Universe's 'missing mass' and found it – or at least some of it.

The School of Physics put out a call for students interested in a six-week paid astrophysics research internship during a recent vacation period, and chose Fraser-McKelvie.  Dr. Kevin Pimbblet, lecturer in the School of Physics put the magnitude of the discovery in context by explaining that scientists had been hunting for the Universe's missing mass for decades.
The figure for you to guess which I posted two days ago is built with simulated events featuring the production, at the Tevatron collider, of a Z boson (decaying to electron-positron or muon-antimuon pairs) together with an energetic photon. Apart from Tulpoeid, who of course knew this since Z-gamma production was her PhD thesis topic, only one other reader posted here a solution close to the correct one.
The Upsilon suppression paper by CMS is now public, and you can find it here. I decided to put an entry here since several people asked me to access the information...

Note that this paper is a quite important publication, which not only deals with Y suppression, but more in general with a quantification of dimuon resonance yields. Happy reading!

While the LHC runs like a swiss train and collects dozens of inverse picobarns a day, there's a celebration going on on the other side of the Atlantic, as this picture testifies:

The folks pictured here at the Fermilab village have a reason to cheer up: the glorious Tevatron has just delivered 11 inverse femtobarns of proton-antiproton collisions to CDF and DZERO. What a huge achievement that has been!
