Governing Physical Laws & Axiomatic Formulations

Under ISO 80000 principles, every unit conversion in this faculty is derived through exact mathematical pathways governing the underlying physical law.

Shannon Information Entropy

H(X)=−∑i=1nP(xi)log⁡2P(xi)H(X) = -\sum_{i=1}^{n} P(x_i) \log_2 P(x_i)

Fundamental measure of average information content or uncertainty contained in a message, measured in bits (shannons).

IEC 80000-13 Binary vs Decimal Capacity

1 KiB=210 B=1,024 Bvs1 KB=103 B=1,000 B1\text{ KiB} = 2^{10} \text{ B} = 1,024 \text{ B} \quad \text{vs} \quad 1\text{ KB} = 10^3 \text{ B} = 1,000 \text{ B}

Strict separation between binary computer memory addressing (KiB, MiB, GiB) and decimal storage manufacturer specifications (KB, MB, GB).

Shannon-Hartley Channel Capacity

C=Blog⁡2(1+SN)C = B \log_2\left(1 + \frac{S}{N}\right)

Maximum theoretical transmission rate (bps) of a communication channel of bandwidth B (Hz) perturbed by Gaussian noise.
