It has been said that it is inevitable for some defeat to enter even the most victorious life, yet the human spirit is never finished when defeated—only when surrendered.
Before we knew what light really was, the equations already had the answer.
c = 1/√(μ₀ε₀) ≈ 3 × 10⁸ m/s
By combining electricity and magnetism, Maxwell discovered that electromagnetic waves travel at exactly the speed of light, leading to a stunning conclusion:
Light is an electromagnetic wave.
Fast Fourier Analysis in action.
Any complex waveform, sound, or shape can be perfectly reconstructed as the sum of simple rotating circles (epicycles).
The concept of logarithms was invented by John Napier, a Scottish mathematician, who introduced them in 1614.
Napier published his discovery in a book titled Mirifici Logarithmorum Canonis Descriptio (Description of the Wonderful Rule of Logarithms), which explained how logarithms could be used to simplify calculations.
