Introduction

Consider this approach to defining ‘electric charge’:

  • Electric charge is a property of matter manifesting in certain of the particle constituents of matter.
  • At one level of explanation of matter, matter consists of atoms.
  • Studying atoms at the first layer of their substructure, viz., the nucleus and surrounding electrons, can provide a fruitful basis for explaining electric charge.
  • As a starting point, note that:
    • Electrons can maintain their location surrounding and revolving about the nucleus only because a radial force of attraction on them exists directed toward the nucleus. Otherwise the electrons would fly off.
  • Experiments reveal that:
    • The force of attraction between the electrons and the nucleus greatly exceeds the gravitational force generated by the masses of the two groups of particles;
    • Therefore a force differing from the force of gravitation is operating, requiring a new designation;
      • For historical reasons discussed later, we designate the force an ‘electric force’.

...the electric force is approximately 42 orders of magnitude larger than the gravitational force. To see the enormity of this ratio, suppose that we represent the gravitational force by an arrow as long as a bacterium. How long would the length of the electric arrow be? Much larger than the height of a man; much taller than the Empire State Building; much larger than the Earth itself; much larger than the solar system; and much larger than the Milky Way. In fact, the electric arrow would be over 10 billion times larger than the "size" of the visible universe! That is why, when electrical forces are present, gravitational forces can be completely ignored.[1] Cite error: Closing </ref> missing for <ref> tag -->

Notes

  1. ↑ Historian John F. Fulton quotes Vesalius as exclaiming:

    I acknowledge no authority save the witness of mine own eyes—I must have the liberty to compare the dicta of Galen with the observed facts of bodily structure.

    • That little piece of amber rubbed by Thales, some 2,500 years ago, appeared then to be very insignificant. Had the world but known, it was fraught with vast possibilities; for, in point of fact, Thales had unconsciously rediscovered Aladdin's Wonderful Lamp. As he rubbed, the Genie of electricity appeared, and demanded, "What wouldst thou have? I am ready to obey thee as the slave of the lamp, I and the other slaves of the lamp." But the question remained unanswered. Neither Thales nor the witnesses of his experiment made any request nor asked its genii to aid them. They had ears, but they heard not, and so the genie disappeared, with all that he was both willing and able to do left undone.

Recommended “Adequate Intake”, 120 mmol/day, identical for men and women, and therefore not adjusted for differences in body size or lean body mass between men and women.
Because the Food and Nutrition Board indicated that eating ordinary foods imposed no danger of consuming excess potassium except in certain potassium non-tolerant conditions, most Americans could likely achieve “adequate intakes” or more by doubling their potassium intake.
