Humans thought that various observed physical effects were caused by different 'forces', each having its own physical domain. Some folk - who began to call themselves 'scientists' - collected many records of those various effects in order to quantify them, even progressing to finding arrangements of mathematics which fitted - or appeared to fit - the actions of those effects. These were rather boastfully called 'Laws of Nature', or separately referred to as 'Laws' of each domain known to the scientists; which were gravitational, electrical, magnetic, and nuclear (which became subdivided into STRONG and WEAK nuclear forces). Eventually scientists realized that when they created an electrical field they also made a magnetiC field, so they combined the two into the electromagnetic force or domain. And then they also realized that the nuclear forces weren't quite independent - the weak nuclear force at least was influenced by electromagnetic fields. so that too was incorporated in the electromagnetic domain. Which gives us two huge domains: gravitational and electromagnetic (with the strong nuclear force [interaction] as an orphan or outsider). If we delve down into the accumulated 'science' of the gravitational domain, we find that it all rests on the behaviour of a piece of matter in a gravitational field of another larger piece of matter. The acceleration is directly proportional to the volume/density of the larger piece of matter - so that volume/density was called gravitational mass. And, delving down into the accumulated 'science' of the electromagnetic domain, we find that it all rests on the behaviour of a piece of charged matter in an electromagnetic field. The direction of the behaviour is determined by the polarity of the charge(s), but the acceleration is inversely proportional to the volume/density of the charged piece of matter; i.e a larger/denser piece of matter (with identical charge) is that much more reluctant to move - so its volume/ density was called INERTIAL MASS. Weirdly, for the scientists - who could see no connection between the two defined masses, the gravitational mass turned out to be the same as the inertial mass - to the limits of measurement accuracy at least. [Both gravitational and electromagnetic effects are inversely proportional to the square of the distance between particles involved - often called the 'inverse square rule'; but it's easily illustrated by candlelight illuminating a sheet of paper at a distance of one yard; when the paper is moved out to two yards it only receives one quarter of the light, in other words you'll need four sheets of paper at two yards to collect the same light as one sheet at one yard. All directly 'radiated' effects follow that rule.] - Here's scientists' comments about the mystery of inertia and of gravitational vs. inertial mass: "The notion of mass as gravitational charge is perhaps the best "theoretical" notion of mass we have. Note that this idea of mass is qualitatively different from the idea of "inertial mass": that quantity which makes it difficult to change the velocity of an object. That these two quantities, gravitational charge and inertial mass, are equal, is another of the fundamental mysteries of physics." - www.rwc.uc.edu "This experience - of the equal falling of all bodies in the gravitational field - is one of the most universal which the observation of nature has yielded; but in spite of that the law has not found any place in the foundations of our edifice of the physical universe." A Einstein, writing in Annalen der Physik,35. (Yup, same problem: inertial mass identical to gravitational mass - Ray) "It is a curious and still not fully understood phenomenon that the inertial mass and the gravitational mass are always exactly the same." John Gribbin in Companion to the Cosmos 1996 ISBN 0- 297-81725-6. and "The reason why things coast for ever has never been found out. The law of inertia has no known origin" Richard P Feynman in The Character of Physical Law (1965) 1992 ISBN 0-14-017505-9. - B.K.R's assessment of our 'scientists' understanding of gravity and e.m.r: "We can describe what happens quite accurately and we think we understand. But really we do not. The invisible influences of gravitation and electromagnetic fields remain magic; describable, but nevertheless implacable, non-human, alien, magic." and of the ongoing inquiry into the mystery of inertia: "If acceleration is relative rather than absolute, then the inertial mass of a body is a measure of the force exerted by the rest of the universe when you push the body. .... [that is] to be contrasted with the search for for the origin of inertial mass pursued through quantum field theory. ... [to] push our concepts of microscopic matter down to infinitesimally tiny dimensions in order to calculate the self-energy, and hence inertial mass, of elementary particles." --Prof. B.K Ridley - in 'Time, Space & Things' N.b. - While I believe the eminent Professor is - as always - right and truthful in his description of the current scientific opinion and state-of-art, I also believe there's at least one more likely frame: in this scenario acceleration _is_ absolute (inc. the acceleration intrinsic in rotation or spin) yet the inertia of any mass (of hadronic matter like we're made of) lies in its interactions with the surrounding "energy-field" of the universe (it's a sort of dynamic radial force-field with an effectively instantaneous [hence multiples of c^2 in calculations] 'speed', acting both inwards and outwards [hence the ubiquitous 'root -1' in all calculations].
