ZD_2_12 — Generative AI: Large Language Models, Diffusion, and the Transformer Revolution

Generative AI refers to artificial intelligence systems capable of creating new content — text, images, audio, video, code, 3D models — that is novel, coherent, and often indistinguishable from human-created work. The fi

Y_3_14 — Chanting and Repetitive Vocalization: Sonic Pathways to Trance

Chanting and repetitive vocalization — the sustained production of rhythmic, patterned vocal sounds — is arguably the most ancient and universal method of inducing altered states of consciousness through acoustic means.
