A unified text analytics dashboard: word/char/sentence counts, type–token ratio (lexical diversity), lexical density, syllable estimate, and separate reading (238 wpm) and speaking (150 wpm) time estimates — plus top content vs function words.

Science & Education

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

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

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

Science & Education

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

Science & Education

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