In his e-book A Temporary Historical past of Time, Stephen Hawking describes his wrestle to elucidate relativistic physics with out utilizing a single equation.
His editor had warned him in actually these phrases: each equation you employ will cut back your readership by half.
Confronted with the vivid chance of near-zero gross sales, Hawking printed A Temporary Historical past of Time with precisely one equation: E = mc².
The e-book offered 25 million copies — a surprising achievement from any angle.
Had Professor Hawking, even for probably the most urgent of wants, included the method for Fisher Data in his e-book, the gross sales figures may need been riveting for an altogether completely different purpose.
For right here lies, in its exquisitely inscrutable glory, the method for Fisher Data:
Examine, if you’ll, the notational nightmare proven above with E=mc².
For bonus bewilderment, the above method comes with the next chewy definition:
Given a random variable X with a chance distribution f(X | θ), the Fisher Data…
