Occam's [or Ockham's] razor (William of Occam [or Ockham]; c. 1340) The suggestion that the simpler a theory is, the better. If two theories predict phenomena to the same accuracy, then the one which is simpler is the better one. Moreover, additional aspects of a theory which do not lend it more powerful predicting ability are unnecessary and should be stripped away. ohm; Omega; O (after G. Ohm, 1787-1854) The derived SI unit of electric resistance, defined as the resistance between two points on a conductor when a constant potential difference of 1 V produces a current of 1 A in the conductor; it thus has units of V/A. Ohm's law (G. Ohm; 1827) The ratio of the potential difference between the ends of a conductor to the current flowing through it is constant; the constant of proportionality is called the resistance, and is different for different materials. Olbers' paradox (H. Olbers; 1826) If the Universe is infinite, uniform, and unchanging then the entire sky at night would be bright -- about as bright as the Sun. The further you looked out into space, the more stars there would be, and thus in any direction in which you looked your line-of-sight would eventually impinge upon a star. The paradox is resolved by the big bang theory, which puts forth that the Universe is non-uniform, dynamic, and (probably) finite.
