(Phys.org)—Scientists beget found that an intricately beautiful yet poorly understood type of crystal found in soap bubbles follows the same mathematical rules as a much better understood type of crystal called martensite. Due to its extreme hardness,martensite has been used since the Iron Age to make swords and horseshoes. The soap-bubble crystals, on the other hand, and which are called smectic liquid crystals (where "smectic" is derived from the Greek word for "soap"),beget turned out to be what the scientists relate as "the world's weirdest martensite."
