The Fourier Transform, explained in one sentence (wonkish)

The Fourier Transform, or more usefully the Discrete Fourier Transform, is a technique to convert a periodically-sampled series of the input into its frequency components. When adding the power component, the resulting series can be displayed as a Spectrogram or perhaps passed down the line to extract clock and symbol data to digital data stream as in the "dem"odulator element of a modem.

After hours reading - The Improbability Principle

Strands of misconceptions, misclassifications,and fallacies entwine to make apparently unlikely events much more probable than you'd otherwise imagine. Mathematics professor David J. Hand unwraps the rope of error types leading to problematic false improbability conclusions in his recent work, The Improbability Principle: Why Coincidences, Miracles, and Rare Events Happen Every Day, (2014, Scientific American / Farrar, Straus and Giraux, NY NY). This conversational read will be useful to, amongst others, engineers engaged in root cause analysis, and counsel defending against circumstantial evidence buttressed by seemingly huge improbabilities.
