Problem: A GRB shows variability on Δt_obs = 0.1 s at z = 1. Assuming emission radius R ≈ 2Γ^2 c Δt_obs/(1+z) must exceed the photospheric radius R_ph = (L σ_T)/(8π m_p c^3 Γ^3), derive an approximate lower limit on Γ for isotropic luminosity L = 10^52 erg/s. (Solution sketch: set R > R_ph, solve for Γ numerically → Γ_min ~ few × 10^2; full algebra in final draft.)
