Mark Thoren and Jim Williams needed to test the temperature compensation scheme of a circuit they were designing. The lab had several temperature chambers, but they were always in use. In frustration, Jim grabbed a brand new toaster and plopped it down on Mark's desk, saying, "This will do." Not quite. The hysteresis of the oven's thermostat was 10C too crude to measure the circuit. Mark and Jim scrounged about and found an auto-tuning temperature controller, some solid-state relays and a shiny platinum RTD probe. After some minor rewiring they had a test chamber, more than adequate and better than most of the "real" chambers that were never available when needed.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
