Dew point from temperature and relative humidity with the Magnus saturation steps shown, and the reverse solve for humidity from a dew point - flagged honestly as an empirical approximation, not a derivation.
C1V1 = C2V2 with M, mM, g/L, mg/mL, % and v/v all normalised through molecular weight, and a serial dilution ladder generator. A zero or negative volume returns a readable error, never NaN.
Standard score from x, mean and sample standard deviation, the reverse from z back to a raw value, and a per-row z-score table for a whole sample. SD = 0 is reported as undefined rather than silently dividing.
Refraction angle between any two media, the critical angle and total internal reflection condition computed and reported, plus unpolarised Fresnel reflectance and transmittance from the mean of s and p.
Scrub 2000 to 2100 and read world population, CO2 ppm and the temperature anomaly, plotted.
Enter a due date and map the pregnancy: current week, trimester, days left and a 40-week grid.
Sort every rotation of a string, take the last column as the encoded form and the sentinel row as the primary index, then walk it back to recover the original text.
Paste a JSON array of objects and get CSV back, or paste CSV and get JSON, with delimiter choice, header detection and a .csv download.
