Supersolidity Achieved in a Photonic Crystal: A Breakthrough

2025-03-11

An international team has for the first time observed a supersolid phase in a photonic crystal polariton condensate, published in Nature. This groundbreaking research introduces a new platform for exploring supersolidity beyond traditional ultracold atomic systems. Supersolids uniquely combine the rigidity of a crystal with the frictionless flow of a superfluid. The researchers achieved this by condensing polaritons within a photonic crystal waveguide, enabling precise measurement of density modulations and probing the local coherence of the supersolid wavefunction. This work not only demonstrates a supersolid phase in a photonic platform but also paves the way for exploring quantum phases of matter in non-equilibrium systems, with potential applications in neuromorphic computing and advanced photonics.

Transhumanism: A Cult for Our Times?

This article explores whether the transhumanist movement exhibits cult-like characteristics. Using Robert J. Lifton's eight criteria for identifying cults, the author analyzes transhumanism's information control, mystical manipulation, purity demands, confession culture, sacred science, loaded language, doctrine over person, and dispensing of existence. The author argues that transhumanism displays similarities to cults in its closed-mindedness, exclusionary practices, and apocalyptic salvation narrative. While not geographically centralized, transhumanism's online communities foster strong group identity and suppress dissent, showcasing blind optimism towards future technologies and devaluation of non-believers. The article concludes that the future trajectory of transhumanism will depend on whether its technological predictions materialize and how its adherents react to reality.

Urine: The Unexpected Origin of Chemistry

In the 17th century, Hennig Brand, a German merchant and alchemist, attempted to extract gold from urine. He collected 5,500 liters of urine, and after boiling and heating it at high temperatures, unexpectedly discovered a new element—phosphorus. This discovery, while not a success in alchemy, marked the birth of chemistry. Brand's discovery eventually led Robert Boyle to refine the method of producing phosphorus and apply it to the creation of matches. More importantly, Boyle openly shared his methods, breaking the secretive tradition of alchemy and advancing the scientific development of chemistry.

Swift Move Semantics: A Comparison with C++

2025-01-09

This article delves into the similarities and differences between move semantics in Swift and C++. Swift automatically performs move optimizations, which is beneficial for performance but can surprise C++ programmers accustomed to the RAII idiom. Swift's "non-copyable types" are similar to C++'s "move-only types," but Swift's moves are destructive, avoiding potential issues with C++'s "non-destructive moves." The article compares Swift's `consume` with C++'s `std::move`, and explains Swift's shortened variable lifetimes, parameter passing conventions (`consuming`, `borrowing`, `inout`), and the Law of Exclusivity. Finally, it discusses using non-copyable types for RAII, generics, and conditionally copyable types in Swift, and why Swift lacks perfect forwarding.
