Formulating quantum chromodynamics in terms of action at a distance is proving very difficult. I have already rewritten the article four times. I am now working on the gluon propagator, and the main difficulty lies in the lack of consensus on its form within QCD theory.

Hartmut Even's claim that the Willow chip "supports the many-worlds idea from physicist David Deutsch" is plain nonsense.

The evidence for perturbative quantum field theory is that the theory predicts (a + b), where b is much larger than a. Then, physicists ignore "b" and claim that the value of "a" agrees with experimental results to ten decimal places.

I have done two consecutive moves. I have new job responsibilities, and a pet has adopted me. I am still working on reformulating quantum chromodynamics. I have little time, but I will try to post material from my "Common Misconceptions in Physics" series daily.

I have finished the research on the geometric foundations of statistics. Now, let us put it to rest so the ideas can mature. My next task will be to prepare a paper on the nonperturbative approach to the strong interaction we conducted a few weeks ago.

Finally, I am developing a purely geometric approach to statistics. We can obtain the formulas for mean, standard deviation, variance, standard error, and regression intuitively. I am currently working on obtaining confidence intervals without probabilistic assumptions.

I am currently doing research in statistics. Trying to reinvent it! I am looking for a simple, intuitive, and robust approach, free from assumptions about "normality", probability distributions, and hypothetical populations. Any ideas or references to modern approaches?

Research update. I finally obtained a gravitational wave equation with a cosmological term. This term is not a constant; it is larger in the past and smaller in the future. However, its current value is consistent with that of the cosmological constant Λ.

Finding a nonperturbative gluon propagator that generalizes the refined Grivob-Zwanziger propagator was a trivial task, but solving the dark energy problem is becoming very difficult. Everything I have tried so far has not worked.

I am testing some ideas about gravitation and nuclear interaction: specifically, dark energy and confinement. Wish me luck!

I have finished the first draft of my review of Waves in an Impossible Sea. Over 320 pages. I am now preparing figures. Contrary to myth, the particles we observe in experiments are not quanta of fields. Also general relativity does not describe gravity as a gravitational field.

1/ I am reviewing the final chapter of Waves in an Impossible Sea, and Strassler closes it with a post-apocalyptic fantasy in which part of his book survives for over 10,000 years in an ancient library, guiding new generations through the 'secrets' of the universe.
