Models often involve separate considerations for macroscopic, microscopic and molecular level phenomena. Composites can fail on the microscopic or macroscopic scale. Algal bloom commonly refers to rapid growth of microscopic, unicellular algae, not macroscopic algae. The discipline of anatomy is divided into macroscopic and microscopic anatomy. This procedure is most common for patients who have unexplained microscopic or macroscopic hematuria. Here are Maxwell's equations, both in macroscopic and microscopic forms. While their input is small compared to trees, microscopic and macroscopic algae also produce isoprene. Therefore, it acts as a link between the microscopic world and the macroscopic. These effects are the reasons quantum mechanics is difficult to observe on a macroscopic scale. The Josephson effect is an example of a macroscopic quantum phenomenon. Those atoms can aggregate into macroscopic phases called inclusions. Empirically based temperature scales rely directly on measurements of simple macroscopic physical properties of materials. This behavior is analogous to the equalization of chemical potential in macroscopic thermodynamics. An example of a physical theory that takes a deliberately macroscopic viewpoint is thermodynamics. The appearance mechanism of this macroscopic chirality is not yet entirely clear.
