ZE_4_13 — Ethics of Wealth and Poverty: Rawls, Nozick, Singer, and Distributive Justice

The ethics of wealth and poverty asks one of the most consequential moral questions: What do the affluent owe the poor? And, more broadly, what constitutes a just distribution of resources? Three towering 20th-century ph

F_2_21 — Ancient Pigment and Dye Trade Routes

Pigments and dyes ranked among the most valuable traded commodities in the ancient world — sometimes rivaling precious metals in cost per unit weight. Lapis lazuli traveled over 4,000 km from mines in Badakhshan (Afghani

ZA_1_03 — Quantum Chromodynamics: The Strong Nuclear Force

Quantum chromodynamics (QCD) is the theory of the strong nuclear force — the interaction that binds quarks into protons and neutrons and holds atomic nuclei together. Unlike electromagnetism, the strong force is mediated

ZA_3_18 — Quark-Gluon Plasma and Exotic Matter States

Quark-gluon plasma (QGP) — a deconfined state of matter in which quarks and gluons, normally bound inside protons and neutrons by the strong nuclear force (quantum chromodynamics, QCD), roam freely over extended volumes

L_1_05 — Human Skin Color — Evolution, Latitude, and Cultural Significance

Human skin color is one of the most visible and most misunderstood traits in our species. The variation is primarily a product of natural selection balancing two competing needs: protection of folate (vitamin B9) from UV
