Science & Education

Photoelectric Effect Calculator

E_k(max) = hν − φ with preset metal work functions or custom φ: threshold frequency, cutoff wavelength, emission verdict, stopping voltage, and photoelectron speed.

Science & Education

Physics Kinematics Problem Solver

Solve 1D constant-acceleration kinematics problems and 2D projectile motion, with a full step-by-step derivation. Enter any 3 of the 5 quantities (displacement, initial velocity, final velocity, acceleration, time) and the solver finds the other two, showing each formula, the substitution, and the result. For projectiles, enter launch speed/angle/height to get range, time of flight, and max height.

Science & Education

Kohlrausch Law Calculator

Λ°m = ν₊λ°₊ + ν₋λ°₋ from the limiting ionic conductivity table, with ion shares as transport numbers.

Science & Education

Molar Conductivity Calculator

Λm = κ/c in S·cm²/mol and S·m²/mol, with optional α = Λm/Λ°m and Ka for weak electrolytes.

Science & Education

Nernst Equation Calculator

E = E⁰ − (RT/nF)·lnQ at any temperature, with the thermal factor RT/F, per-decade step 2.303RT/nF, and ΔG = −nFE.

Science & Education

Lorentz Force Calculator

F = |q|·v·B·sinθ on a moving charge, with charge units down to elementary charges, speed and field selectors, and the v × B direction flipped for negative charges.

Science & Education

Lorentz Factor Calculator

γ = 1/√(1−v²/c²) with 1/γ, βγ, and √(1−β²) for any subluminal speed — the single number behind all of special relativity.

Science & Education

Optical Magnification Calculator

M = 250/f for magnifiers, (L/f_o)·(250/f_e) factorized for microscopes, f_o/f_e for telescopes.

Science & Education

NMR / IR Spectroscopy Peak Predictor

Predict characteristic ¹H / ¹³C NMR shifts and IR bands from the functional groups you select — annotated simulated spectrum, carbonyl discrimination table, every peak explained.

Science & Education

Microscope Scale Bar Calibrator

Calculate microscope object scale, field of view, diffraction limits, Nyquist sampling, and download a transparent SVG scale bar.

Science & Education

Maxwell Stress Tensor Calculator

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.

Mendelian Punnett Square Calculator

Build a Punnett square for a Mendelian cross and auto-calculate genotype and phenotype ratios. Supports complete dominance, incomplete dominance (blending), codominance, and X-linked (sex-linked) inheritance — with each offspring cell's sex marked for X-linked crosses.
