A Tiny Crevice. In other words, it is also called an affordance, permissiveness, or tolerance. A 5mm hole and a 5mm rod don’t fit perfectly together. If you hit it with a hammer, the rod might go into the hole, but only by forcing it. If they are the same size, they don’t really fit. There needs to be a slight gap to ensure a proper fit, which is known as ‘engineering tolerance.’ In this world, 5mm exists only as a concept and doesn’t truly confirm its existence. For some, ‘tolerance’ might be seen as a mistake or imperfection, but for others, it’s a principle of life that drives the world and should be natural. - Joseph’s “just my thoughts”
