The hazard-based approach is valid and very important, but it does not interact well with the 'AoG' concept, since that denies that a current hazard (such as a very near future volcanic eruption) is/has been identified. Best wishes With seasonal felicitations John Woodgate OOO-Own Opinions

Hi John A. and all: A different process than “risk assessment:” A hungry polar bear is a hazardous energy source. The bear’s energy exceeds John A.’s defensive energy, thus John A. can expect to be injured or worse during a polar bear encounter. The safeguard for John A. is

To be an AoG, the test has to be 'No-one would have thought of that.' I don't know much about how the 'functional safety' experts have re-normalized their infinities, but I believe that, having acknowledged that 'anything not violating the laws of physics can happen', nevertheless have

The volcanologists are not good enough. No human knowledge is exhaustive.  It fits fairly well with your cited definition: /an act or occurrence so extraordinary and unprecedented that human foresight could not foresee or guard against it/ but I think the definition is 'over-egged': I would

Two thoughts on this: 1) it sounds from the the description of the event that this might also be called a “black swan” event. As we all know, black swans are real, however rare they may be. This is simply another way to say “We never thought of that”, and 2) I had a Trek mountain bike that had

I can't think of an internal fault in a product that would fit the 'Florida' definition of AoG. Unforeseen physical and chemical effects are not extremely rare; a case that comes to mind is 'white plague', a gold-aluminium compound that formed in some early ICs and cause premature failure. But

Thanks for sharing Rich. I'd be interested if there is a follow up to this article at all. There seems to be some strong implications stated in the article that I'd assume there would be some type of rebuttal possibly in an editorialial reply. Have a Happy New Year all. Curt
