One could then define the unit of current, as the current which, when flowing in a straight wire, attracts a similar current in a parallel wire 1 meter away with a force of unit strength, for every meter of the wires' length. ... Faraday also showed that a magnetic field which varied in time--like the one produced by an alternating current (AC)--could drive electric currents, if (say) copper wires were placed in it in the appropriate way. ...

10. Electromagnetic Waves
Perhaps the greatest theoretical achievement of physics in the 19th century was the discovery of electromagnetic waves. ... It is possible to use this to define a unit of electric charge, as the charge which repels a similar charge at a distance of, say, 1 meter, with a force of unit strength (actual formulas make this precise). ... But "field" originally only meant the force a magnet or an electric charge could expect at a point in space, if it were placed there. ...

... Needs for precise timing There exists a broad spectrum of needs for precise timing, extending from the most demanding requirements of satellite navigation systems for a continuous atomic time scale accurate at the level of nanoseconds, through the increasing number of precise time- stamping or dating systems working at the level of milliseconds, to the far end of this spectrum where space geodesy, space navigation and astronomy require the orientation of the Earth at the level of microseconds. ...

For around forty years, astrophysicists have observed the annihilation of positrons in the Galaxy at a prodigious rate. ... The fact the Galactic bulge far outshines the disk in annihilating positrons which are injected into the ISM at low energies makes the source of the positrons difficult to identify, as the main source of such positrons are prima facie located in the Galactic disk. ...
