Five lanterns light the same question: they say where they agree, where they part, what each could not see and why; they show the closest-to-true data within reach — and build the answer on that. To believe or not, to judge — that stays with you; ask for a fresh check whenever you wish. To err is human — five lanterns can err too; we look, we fix. Cheerfully, then: measure, weigh. Come in.
