Kevin, OT <[Yousef's] posts aren't making any sense> Formally they are not, it's true. However, his recent posts show how narrow his education is. There are MANY "right hand" rules. One of the "right hand rules" is a freshman tool to memorize the direction of a "vector product" (or "cross product") of ANY TWO vectors. This important binary operation defines the whole layer of abstract mathematical models called "vector algebras". The other area of applications for the "right hand rules" goes to DIFFERENTIAL algebra of vector fields. The "curl" (which Yousef was barely able to spell out) is an object that describes the "rotational" properies of smooth vector fields; in many sciences it is called as "rotor". For example, the curl of a magnetic field in a conductive media would define the direction of local current. Plasma physics is full of examples on the topic. For a simplified "straight" geometry like a conductive wire the "rule" will help to determine the direction of current, or the direction of "curly" magnetic field around the wire (whichever is unknown). Acutally, the curl has a simple relation to the "vector product": the curl itself can be defined as a vector product of the differential "del" operator and the field vector itself, therefore are the similarity in "rules". Yousef's attempt to show off elementarity of his education is spectacular. No wonder he cannot rise his head above his transistors to see a bigger picture of logical gates/cells, then macro blocks (registers/shifters/decoders), then overall dataflow architecture (prefetching, decoding, scheduling, execution, retirement/load/store), then to cache designs and interconnect problems, to overall balanced system and board signal integrity, to firmware (BIOS) support and configuration, up to operating system time and multiprocessor sharing, up to ... to ... ... and eventually, to correct interpretation of benchmark results.
