- God Does Play Dice With The Universe (And The Dice Are Fair)
-
Want to get into a bar fight at a physics conference? Argue that quantum mechanics is the best way to predict outcomes. Or argue the opposite. A new paper argues that quantum mechanics is close to optimal in terms of its predictive power but even if all ...

- Eric Weinstein's Geometric Unity Has A Fundamental Flaw. No Lagrangian, No Theory
-
E ric Weinstein's theory of Geometric Unity is wrong. So is every other so-called theory of everything that anyone has proposed so far. His has a deeper problem, however. A theory in physics derives its prediction by way of a energy like quantity c ...

- Reference Letters
-
Lately I have been writing lots of reference letters for students who are applying to Ph.D. positions in Physics, and in so doing I have found myself pondering on the dubious usefulness of that exercise. So let me share a bit of my thoughts on the matter h ...

- Extrasensorial Plot Premonition
-
In the previous article here, I tangentially examined a situation that arises often in collaborative data analysis: the digestion of the results in scientific graphs. The focus of that discussion was the building of a sceptical thinking attitude in my stud ...

- Swedish Physics Days
-
On August 13-15 I will attend for the first time to the Swedish Physics Days, an important national event for Swedish physics. This year the congress takes place at Lulea University of Technology, the institute where I am currently spending some time, host ...

- Some Thoughts On Co-design For Tracking Optimization
-
These days I am organizing a collaborative effort to write an article on holistic optimization of experiments and complex systems. "So what is the news," I could hear say by one of my twentythree faithful readers (cit.) of this blog. Well, the n ...

- A Remarkable Graph: The Full Dalitz Plot Of Neutron Decay
-
The neutron is a fascinating particle, and one which has kept experimental physicists busy for almost a century now. Discovered by James Chadwick in 1932 in a cunning experiment which deserves a separate post (it is a promise, or a threat if you prefer), ...

- Searching For Impossibly Rare Decays
-
I recently ran into a description of the Mu3e experiment, and got curious about it and the physics it studies. So after giving it a look, I am able to explain that shortly here- I think it is a great example of how deep our studies of particle physics are ...

- Gregory Ryskin On Vacuum Energy
-
Although unconventional, the ideas of Gregory Ryskin on vacuum energy sound interesting to me, so I invited him to share them with you in this guest post. Ryskin's physics journey began with fluid dynamics, first in Russia, then in the US, at Caltech ...

- How Elementary Particles Die
-
A preamble Subnuclear physics obeys the laws of quantum mechanics, which are quite a far cry from those of classical mechanics we are accustomed to. For that reason, one might be inclined to believe that analogies based on everyday life cannot come close ...
