In his e-book A Brief History of Time, Stephen Hawking describes his battle to elucidate relativistic physics with out utilizing a single equation.
His editor had warned him in actually these phrases: each equation you employ will scale back your readership by half.
Confronted with the vivid chance of near-zero gross sales, Hawking revealed A Transient 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 essentially the most urgent of wants, included the method for Fisher Data in his e-book, the gross sales figures might need been riveting for an altogether totally different motive.
For right here lies, in its exquisitely inscrutable glory, the method for Fisher Data:
Evaluate, 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 likelihood distribution f(X | θ), the Fisher Data…
