ZG_3_16 — Sign Language Typology: Structure, Diversity, and the Linguistics of Gesture
Sign languages — natural human languages that use the visual-gestural modality rather than the vocal-auditory channel — are among the most powerful demonstrations that human linguistic capacity is not bound to speech. Th
ZG_3_01 — Sapir-Whorf Hypothesis — Does Language Shape Thought?
The Sapir-Whorf hypothesis — more precisely, the principle of linguistic relativity — proposes that the structure of a language influences or determines the habitual thought patterns, perception, and worldview of its spe
Q_4_25 — Time Crystals: Wilczek and Experimental Realization
A time crystal is a phase of matter that spontaneously breaks time-translation symmetry, exhibiting periodic motion in its ground state or steady state without energy input — the temporal analogue of how ordinary crystal
ZB_5_14 — Conservation Biology
Conservation biology — the scientific study of biodiversity loss and the methods to protect species, habitats, and ecosystems — was formally established as a discipline by Michael Soulé (University of California, San Die
ZB_5_18 — Insect Decline Crisis

H_2_14 — Funding Bias in Science: Who Pays, Who Decides, What Gets Studied
Scientific research is shaped not only by curiosity and methodology but by who funds it — and funders' priorities, interests, and incentive structures systematically influence what questions get asked, what methods are u
H_1_08 — Destruction of Nalanda and Asian Knowledge Centers
