"When will ..." questions are mostly impossible to answer. Some can be answered by definition, like "When will the next century start?". Some can be answered with a high degree of confidence, based on well established systems and mechanisms, like "When will the next full moon be?". Answers can be hazarded on a few more -- such questions as "When will it next rain in London?".

The date of a forthcoming (or possibly never coming) mathematical discovery fits none of these categories.

However, I have a scientific hypothesis: a proof that

**pi** is normal will be published on August 23, 2516.

According to an outdated view of the scientific method, I am quite entitled to use that as a working hypothesis until it is disproved. As far as I can see, that could only happen in one of two ways -- arrival of that date, or an earlier proof/disproof of the normality of

**pi**. I do not expect to be around for either event.
