The development of a quantitative structural platform for experimental biologyextending across a hierarchy of sizes ranging from molecules to organisms-has been punctuated by a series of major achievements over the last 30 years. Stereology, a form of quantitative morphology, has contributed handsom

A peculiar deformation in the threadline region resembling the "necking" associated with cold drawing of some metals and many polymeric fibers is observed when polyethylene terephthalate (PET) and other semicrystalline polymers are meltspun at high speeds. This phenomenon is often referred to as the
## Abstract Five kinds of polylactides (PLAs), with different Dβlactide contents and tacticities, were subjected to highβspeed meltβspinning experiments. In addition to stereochemical purity, the PLA types differed in molecular mass and molecular mass distribution. The properties of the different P
