There are a lot of things I like about Rust in this function. At a glance, I can tell a1 and a2 are both i32. I can tell that sub_operation_1 and sub_operation_2 both return my custom Result type. And I know this function is extremely unlikely to panic or fail in some unpredictable way. It can fail, but when it does, it bubbles that responsibility up to the caller in a structured, traceable way. You know what failed and where.

One reason is that symmetries are very common in many theories of nature. Space-time itself has symmetries, for instance. There are no special directions, no special places, and no special times. But we do have special scales: The world looks one way to humans, another way to bacteria, and yet another way to electrons. That’s peculiar. So I think it’s a natural assumption to say that at the fundamental level, maybe there are no special scales. Maybe there is a symmetry between scales, a scale symmetry.。新收录的资料对此有专业解读
