R_2_04 — Homo Floresiensis: The Hobbit Mystery

In 2003, a team of Australian and Indonesian archaeologists discovered a tiny, near-complete hominin skeleton in Liang Bua cave on the island of Flores, Indonesia. Designated Homo floresiensis (Brown et al. 2004, Nature)

ZA_2_13 — Quantum Gravity Approaches

Quantum gravity is the unfinished quest to unify general relativity (GR) — which describes gravity as spacetime curvature at macroscopic scales — with quantum mechanics (QM), which governs microscopic physics. The challe

ZA_2_11 — Spacetime Foam and Quantum Gravity Effects

At the Planck scale — lengths of ~$1.6 \times 10^{-35}$ m and times of ~$5.4 \times 10^{-44}$ s — quantum mechanics and general relativity collide, and the smooth spacetime continuum of Einstein's theory is expected to b

ZA_4_03 — The Electromagnetic Spectrum: From Radio Waves to Gamma Rays

The electromagnetic spectrum encompasses all forms of electromagnetic radiation — from radio waves with wavelengths of kilometers to gamma rays with wavelengths smaller than atomic nuclei. Unified by James Clerk Maxwell'

ZA_4_08 — Photon Physics and the Nature of Light

The photon — the quantum of the electromagnetic field — is simultaneously one of the most familiar and most enigmatic particles in physics. Planck's introduction of energy quanta (E = hf, 1900) and Einstein's explanation
