If the units made a difference to your degree of understanding of EM, I would suggest that your understanding isn't all that good. Bob M.

Quite impressive! ===================================== Ref: http://hkacc203.org/_notes/Pace%20Stick%20Training%20Note.pdf "With the pace stick open to 750mm (30 inches) stand to Attention as normal." A pace is two steps, one for each leg, and even short me can step 2.5 feet, or pace 5 feet, 5000 feet to a mile. Quite unimpressive given 5280 feet to the mile... unless you are a dwarf.

If the beauty of Helen of Troy could launch a thousand ships then the amount of beauty needed to launch just one ship must be the milliHelen. http://www.merriam-webster.com/dictionary/object Date: 14th century 1 a : something material that may be perceived by the senses <I see an object in the distance> b : something that when viewed stirs a particular emotion (as pity) <look to the tragic loading of this bed.the object poisons sight; let it be hid - Shakespeare> 2 a : something mental or physical toward which thought, feeling, or action is directed <an object for study> <the object of my affection> <delicately carved art objects> b : something physical that is perceived by an individual and becomes an agent for psychological identification <the mother is the primary object of the child> 3 a : the goal or end of an effort or activity : purpose, objective <their object is to investigate the matter thoroughly> b : a cause for attention or concern <money is no object> 4 : a thing that forms an element of or constitutes the subject matter of an investigation or science 5 a : a noun or noun equivalent (as a pronoun, gerund, or clause) denoting the goal or result of the action of a verb b : a noun or noun equivalent in a prepositional phrase 6 a : a data structure in object-oriented programming that can contain functions as well as data, variables, and other data structures b : a discrete entity (as a window or icon) in computer graphics that can be manipulated independently of other such entities synonyms see intention Date: 15th century transitive verb : to put forth in opposition or as an objection <objected that the statement was misleading> intransitive verb 1 : to oppose something firmly and usually with words or arguments 2 : to feel distaste for something That's one of the beauties of the English language: each term can mean dozens of different things. |
