I hate people who try to show their intellectual superiority by asking people to answer esoteric questions. It only reveals them to be annoying pedants. Knowing random facts is not a sign of intelligence. Smarmy Piers Morgan tried to embarrass a person on a reality show by asking her “Do you know what Pythagoras’s theorem is to the nearest five decimal places?” and embarrassed himself instead, as this clip shows.
There are so many things wrong with that one question and answer. One is shown in the video in that when his co-host challenged him to answer his own question, he said “3.147”, revealing that he had confused the famous theorem with the number pi. Maybe he thought that the person credited with the discovery of the theorem was called Pi Thagoras and had also decided to name the number after himself.
But there are other errors that reveal deeper idiocies lurking in what we can laughingly refer to as his brain.
One is that a theorem is a statement about propositions and will never be just a single number. The second is that it makes no sense to ask for the nearest five decimal places of a number. The third is that he himself gave only three decimal places after asking for five, suggesting that he does not know what ‘decimal places’ means. The fourth is that even that was wrong since the value of pi to five decimal places is 3.14159. And finally if he was rounding to just three decimal places, it would be 3.142.
His number of errors per word rating is simply off the charts. But this is Smarmy Piers in classic Dunning-Kruger mode, too ignorant to know that he is ignorant.
