Converts a logarithm from one base to another.
Probability that an event does not occur.
Energy cannot be created or destroyed, only transformed.
Position and momentum cannot both be known with unlimited precision.
Maximum efficiency of a heat engine.
Genotype frequencies in a non-evolving population.
Phenotype ratio from a heterozygous monohybrid cross.
Phenotype ratio from a dihybrid cross.
Energy of a mass in another body's gravitational field.
Latest date a deferred defect must be fixed: the discovery date plus the Minimum Equipment List category interval. The day of discovery is “day zero” and is not counted.
Rule-of-thumb bank angle (degrees) for a standard-rate (3° per second) turn from true airspeed in knots.
Output adjusted for inflation, so growth reflects real production, not rising prices.
A broad price index covering all goods in GDP, not just a consumer basket.
Convert an amount from one currency to another using the quoted exchange rate.
Earth's rotation period measured against the stars, not the Sun.
Exclusive OR: true when exactly one input is true.
Represents negative integers in binary by inverting bits and adding one.
Frequency of a note n semitones from a reference pitch.
An octave above a note has exactly double its frequency.
Overtones of a note are whole-number multiples of the fundamental.
Lowest note of a pipe open at both ends (like a flute).
Theoretical top displacement speed in knots from waterline length in feet.
One knot is one nautical mile per hour.
Money set aside for claims incurred but not yet fully paid.
Weighted average of the utility of outcomes, not just their cash value.
One strategy dominates another if its payoff is always higher.
Maximum possible cooling efficiency between two temperatures (in kelvin).
Flips |0⟩ to |1⟩ and vice versa — the quantum equivalent of a classical NOT gate.
Two-qubit gate that flips the target qubit only when the control qubit is |1⟩.
Multiple successive discounts are NOT additive. Multiply the remaining fractions: 20% off then 10% off = 0.8 × 0.9 = 0.72, meaning 28% total discount (not 30%).
When raising an exponent to another power, multiply the exponents: (aᵐ)ⁿ = aᵐˣⁿ. Simplifies nested exponents instantly.
Apply successive discounts by multiplying the "keep" fractions, not by adding the percentages. The result is always less than the sum of discounts.
Round each number to a friendly value, compute, then note the direction of error for a quick sanity check.
C(n, r) = n! ÷ (r! × (n−r)!). Order does not matter.
Average speed over equal distances is the harmonic mean: 2ab ÷ (a + b), not the plain average.
