Long before the magnetic compass reached European shores, Viking sailors may have read the sky itself to find their way across open ocean — a theory as elegant as it is unproven. Researchers at a European university have turned this enduring historical mystery into a laboratory exercise, inviting undergraduate physics students to test the so-called sunstone hypothesis by building sun compasses and measuring atmospheric polarization. In doing so, they offer students something rarer than a technique: the experience of holding a beautiful idea accountable to evidence.
