When you measure something three different ways and you get the same result each time, the proper conclusion is that you're actually measuring what you claim to be measuring, not that you're experiencing a coincidence or a hoax.
quote:
Unless what you are measuring is, say, cupcakes, and you find that they are all composed of similar but different proportions of sugar and flour and eggs and baking powder, amazing coincidence, and then you also check the recipes by which they were made, and oh double amazing coincidence, there is the flour, the sugar, the eggs and the baking powder, and in VERY SPECIFIC QUANTITIES TOO, oh happy day.
You are misunderstanding.
When crash talks about measuring something three different ways, it isn't like having the same three recipes, or even just similar recipes.
It's like checking a fact in a criminal investigation; corroborating evidence from several independent sources tends to increase one's confidence that the fact is correct.
