Physicists Discover Particle with Mass Only When Moving in One Direction

Scientists have discovered a peculiar quasiparticle, the semi-Dirac fermion, which only exhibits effective mass when moving in one direction. Predicted in 2008, this phenomenon has now been confirmed in a ZrSiS semi-metal crystal at extremely low temperatures (-269°C). Its energy properties differ drastically in perpendicular directions, akin to a train experiencing resistance when switching tracks, thus gaining mass. This discovery could have profound implications for quantum physics and electronic sensors, but further research is needed to explore its applications.

From Hackers to AI Devs: Has the Spirit Changed?

This article contrasts the hacker culture of the 90s with the culture of today's AI developers. 90s hackers were rebels, using technology to challenge authority, their actions closer to art than engineering. Modern AI developers, however, are often constrained by corporate environments and regulations, their work more process-driven. While tools and technology have drastically changed, the core spirit of pushing technological boundaries remains, albeit expressed differently. Some AI developers are rediscovering this spirit through open-sourcing models, building local inference engines, and challenging tech giants and established norms.

Time as an Object: Assembly Theory Redefines Time's Nature

2025-06-25

Challenging conventional views, Assembly Theory, proposed by Sara Walker and Lee Cronin, posits that time is not an illusion or backdrop, but a measurable physical object with size and unidirectional flow. This theory, drawing parallels to Darwinian natural selection, quantifies selection by making time a property of objects, emerging only through evolution. Life, it argues, arises when the universe selects from an immense space of possibilities. Assembly Theory acts as a universal life detection system, measuring assembly indexes and copy numbers of molecules. The theory explains the existence of complex objects like computers and LLMs by positing that time itself, materialized through assembly processes, is the fundamental stuff they're made of. This revolutionary perspective holds significant implications for our understanding of life's origins and the universe's evolution.

Sixteen Colors: An Online Archive of ANSI/ASCII Artpacks

Sixteen Colors is an online archive preserving ANSI and ASCII artpacks, a form initially designed for text-mode computer consoles. Popularized in the early 90s with the rise of dial-up Bulletin Board Systems (BBSs), artists formed groups releasing monthly artpacks, sparking fierce competition (like between ACiD and iCE). The internet's rise in the late 90s diminished BBSs and the demand for ANSI/ASCII art, yet artists continue the tradition. Sixteen Colors aims to publicly archive this legacy.
