This morning’s Advanced Computational Mechanics examination was surprisingly simple. There were many questions along the lines of “show that k* = sin (klΔ)/Δ” which made life very easy.

Once you arrive at the correct answer, you can simply end it with a grand QED. The task of proofreading the answers is remarkably simple, since the correct answer is already supplied, and you just have to get there. It is highly improbable, although not exactly impossible, for conjugated pairs of errors to crop up in the workings and then happily cancel out each other so that the final solution happens to be the right one.


I very nearly got a high from writing QED.

If I hadn’t so royally messed up the assignments, a First Class Honours grade for this subject would have been in the bag. But seeing that it is not the case, we’ll see what happens.


QED is an abbreviation for the Latin phrase "quod erat demonstrandum" ("that which was to be demonstrated"), a notation which is often placed at the end of a mathematical proof to indicate its completion. [source: Mathworld]

QED is also an abbreviation for quantum electrodynamics. The book “QED: The strange theory of light and matter” by the late Richard P Feynman is an extremely insightful book derived from a series of public lectures aimed at the general public. “QED: the strange theory of light and matter” is available in both the Rowden White Library and the Baillieu Library at The University of Melbourne.
