Webster's Revised Unabridged Dictionary
    • n Erg (Physics) The unit of work or energy in the C. G. S. system, being the amount of work done by a dyne working through a distance of one centimeter; the amount of energy expended in moving a body one centimeter against a force of one dyne (981 dynes exert the same force as a one gram mass in the earth's gravitational field). One foot pound is equal to 13,560,000 ergs. The absolute Joule is equivalent to 107 ergs, which are equivalent to 0.2389 gram-calories at 15° C. See also mechanical equivalent of heat under equivalent.

    • n erg In physics, the unit of work in the centimeter-gram-second system—that is, the amount of work done by the unit of force, one dyne, acting through the unit of distance, one centimeter. One foot-pound is approximately equal to 1.356 × 10 ergs, and one horse-power (English) is equal to 7.46 × 10 ergs per second. Also ergon.

    • n Erg erg the unit of work in the centimetre-gramme-second system—that is, the quantity of work done by a force which, acting for one second upon a mass of one gramme, produces a velocity of one centimetre per second.

Definitive diagnosis requires referral to a specialist for an electroretinogram (ERG), so Isaac's owner cut his trip short and came back to take his boy to the ophthalmologist and neurologist.
Several days later, after three ERGs, cerebral spinal fluid tap, and an MRI, Isaac was diagnosed.

In science:

We present a new model for low-luminosity X-ray sources in globular clusters, with LX . 1034 erg s-1 .
Bondi-Hoyle-Lyttleton Accretion Model for Low-luminosity X-ray Sources in Globular Clusters
There is also a population of dim cluster X-ray sources (DCXSs), with LX ∼ 1031 - 1034 erg s-1 , where the lower limit is set by the detection sensitivities.
Bondi-Hoyle-Lyttleton Accretion Model for Low-luminosity X-ray Sources in Globular Clusters
In this case, only when a NS passes within . 0.1 pc of a mass-losing AGB star might the density be sufficiently large to yield an accretion luminosity & 1030 erg s-1 .
Bondi-Hoyle-Lyttleton Accretion Model for Low-luminosity X-ray Sources in Globular Clusters
For instance, if we assume a gas temperature of 104 K, then the maximum accretion luminosity of a nonmagnetic NS is LX ∼ 1032n erg s-1 (eq. ).
Bondi-Hoyle-Lyttleton Accretion Model for Low-luminosity X-ray Sources in Globular Clusters
The energy provided by Type II supernovae is estimated by assuming ESN = 1051 ergs is released from stars with initial masses > 8M⊙ and that ηI I Type II supernovae are produced per solar mass of stars formed.
