The following is my email correspondence with Joy Christian. It shows how seriously he took my bait and how he quite agreed with my main point, namely that the “Quantum Crackpot Randi Challenge” should be earnestly attempted.
Somebody who just does not believe in what modern experiments observe, say relativity, is a common crackpot, nothing too bad – could be a nice guy. However, telling people incessantly to have the model that explains quantum experiments while carefully hiding that he actually does not accept those experiments, that is outright dishonest. Obnoxious his insistence about…
Summer conferences are just around the corner, and the LHC experiments are putting together O(1 fb) samples as we speak (in another post I will report on the progress of data collection at CMS, which has already collected over 650 inverse picobarns of useful data). It seems that this is a good time to make the point of where we stand with Higgs boson searches.
I am speaking, of course, of the Standard Model (C) Higgs boson, the only one which exists (maybe). Fancier concoctions, predicting five, eleven, or exp(pi) new scalars will be reviewed another day when I am under drugs.

WTF. A pleasant, unexpected surprise awaited me in the CMS Times, the online periodical which reports on the status of the CMS experiment at the Large Hadron Collider, the research activities, the people participating in the experiment.
The surprise is that my piece on Upsilon suppression, which you, dear readers, got to read first on this site, is quoted and linked in the front page of the last edition. If I were just an ounce more arrogant and proud, I would claim that they just did the right thing, and that my piece was more accurate in a few details than a similar one appeared on the…
The fact that I am swamped by the too many activities I am involved in these days can be gauged by things like the following: I get to know about important new physics results coming from an experiment I am part of by... private communications from amateurs! Knowledgeable and informed ones, of course -but that's not the point.
So the news I got from Tony Smith today is that the jet-jet resonance unearthed by CDF in W+jets events, the one which made everybody cry Higgs just one more time about two months ago, is still there once data a significant amount of new data (three more inverse…
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.
The riddle of…

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…

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. Similarly, before the ball going to the right is about to arrive at Bob’s crystal, Bob…
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.
Some years ago while playing with physics, fractals and…

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. It was less of a big deal then because the LHC hype machine was still in full swing even though it had already been delayed. Everyone expected that with its much greater luminosity the LHC would find the eponymous "God particle" (since, as Peter Higgs said, no one around him…
