Considering our age and our lives, we are probably less exposed than most to the likely consequences of the dramatic changes in geopolitics that are about to unfold, threatening, never mind threatening, much more likely irreversibly damaging, destroying the rules-based world order that characterized the past 80 years. Nonetheless, I feel depressed, frustrated, anxious to the point that I no longer even enjoy some of my favorite television shows. Something as mild as a mistaken identity or a shared secret is enough to trigger a sense of anxiety, which I do not welcome.
Instead, I need distractions. Seriously, all I want to do is to play with our cats or dig into physics. Preferably both. Yes, I often consult with our cats when I think about physics.
Earlier tonight, I was thinking about the Einstein stress-energy-momentum pseudotensor and its possible uses, despite its shortcomings. The nonlocality of the energy of the gravitational field is a fascinating topic, and I keep wondering if it is directly connected somehow to the quantum nature of the universe in which we live.
