Science & Education

LC Oscillation Frequency Calculator

LC tank resonance f = 1/(2π√(LC)) with inductance and capacitance selectors, plus ω, period, and characteristic impedance √(L/C).

Science & Education

Length Contraction Calculator

L = L₀/γ for any subluminal speed: contracted length, contraction percentage, and the transverse-invariance note — muon-atmosphere companion included.

Science & Education

Lens Maker Equation Calculator

1/f = (n−1)(1/R₁ − 1/R₂) with diopters, focal length, and converging/diverging classification; R = 0 marks a plano surface.

Science & Education

Faraday Electrolysis Calculator

m = M·I·t/(n·F) with unit selectors for current and time: charge passed, moles of electrons, and the mass deposited.

Science & Education

Faraday Induction EMF Calculator

Faraday's law |ε| = N·ΔΦ/Δt with turns, flux, and time selectors, plus the Lenz's-law sign explained — one turn and one weber per second induce exactly one volt.

Science & Education

Wavefunction Expectation Value Calculator

Trapezoidal ⟨x⟩, ⟨x²⟩, σ_x and ⟨ψ|ψ⟩ = ∫ψ²dx from pasted real ψ(x) samples — inner products for any discretely sampled wavefunction.

Science & Education

Fermentation Starter Brix & Timelapse Tracker

Log Brix / specific-gravity readings over time, plot the decay curve, compute apparent attenuation & projected ABV, and predict the fermentation end-point

Science & Education

Electric Field of a Point Charge

E = k·|Q|/r² in N/C with charge and distance unit selectors, the radial direction from the sign of Q, and the force an electron would feel at that point.

Science & Education

Electric Potential Calculator

V = k·Q/r with the sign preserved, plus the electron potential energy U = −e·V in eV — at the Bohr radius this reproduces 27.2114 V, twice hydrogen's ionization energy.

Science & Education

Capacitor Energy Calculator

U = ½·C·V² with capacitance and voltage unit selectors, the stored charge Q = C·V, and auto-scaled energy output.

Science & Education

Diffraction Grating Calculator

d·sinθ = mλ from lines/mm: spacing d, diffraction angle per order, and the m_max cap — HeNe and CD examples included.

Science & Education

Double-Slit Interference Calculator

Δy = λL/d with first-order angle and the first four fringes each side — the ruler-measurable student bench classic.
