  • • Despite sanctions, Russia adapts by engaging with strategic partners like China to circumvent restrictions.

    • China has replaced Western nations as a major supplier of goods to Russia, with trade between the two reaching $240 billion in 2023. In 2021, the total trade between the two countries was approximately $147 billion.

    • Specific exports from China to Russia include CNC machines, semiconductors, microelectronics, ball bearings, nitrocellulose, drones, and construction equipment.

    • The Sino-Russian relationship has deepened, with both nations criticizing the U.S. and increasing their cooperation.

    Bottom line: China don’t care. But we knew this already.





  • Summary: In 2022, Carolina Figueiredo discovered collisions involving three different subatomic particles produced identical outcomes, suggesting a hidden connection between seemingly unrelated particle theories. This finding supports the idea that space-time and quantum mechanics are approximations of deeper, abstract principles. Her advisor, Nima Arkani-Hamed, had previously discovered a geometric object called the “amplituhedron,” but Figueiredo’s discovery points to a new method, “surfaceology,” which simplifies particle interactions without relying on traditional Feynman diagrams.

    The traditional way of understanding particle collisions uses Feynman diagrams to track all possible particle paths, which is mathematically intensive. Surfaceology offers a more efficient and direct way to arrive at the same predictions without needing to track these countless possibilities, allowing physicists to see the results of collisions more clearly and directly.

    Surfaceology may eventually bypass the need for space-time as a fundamental concept in physics. This hints at a potential new understanding of quantum gravity and the origins of the universe, and echoes past revolutionary changes in physics.
