Media

Run a full music mastering chain on one track: sub-rumble high-pass, corrective EQ, glue compression, character EQ, saturation, stereo widening, true-peak limiter, and two-pass linear loudness normalization to 2026 platform targets.

Science & Education

T_ij = ε₀(E_iE_j − ½E²δ_ij) + (1/μ₀)(B_iB_j − ½B²δ_ij) from the full E and B vectors, with the 3×3 matrix, energy densities, trace check, and traction on a chosen surface.

Math & Numbers

MST with both textbook algorithms: Kruskal's sorted accept/cycle-reject log and Prim's component growth, cross-checked to agree on the total weight; disconnected graphs rejected.

Health

Convert mEq ↔ mg/mmol (or mEq/L ↔ mmol/L, mg/L) from molecular weight and valence: mEq = mmol × valence, mg = mmol × MW. Not medical advice.

Health

Calculate MAP = DBP + (SBP − DBP)/3. Normal 70–100; ≥65 sepsis target; <65 hypoperfusion. Derived from Geddes 1984, SSC 2021, BTF 2017, StatPearls, LITFL. Not medical advice.
