The FERS annuity is based on a specified percentage (either 1% or 1.1% for most employees, see below), multiplied by (a) the length of an employee's Federal service eligible for FERS retirement (referred to as "creditable Federal service", which may not be the actual duration of Federal employment) and (b) the average annual rate of basic pay ...
The FERS program takes into account the years served and the average pay for the top three years in terms of payment. For example, a member elected before 1984 and thus qualifying under the CSRS plan, who worked for 22 years and who had a top three-year average salary of $154,267 would be eligible for a pension payment of $84,847 per year.

The organic compound 1,1,1-trichloroethane, also known as methyl chloroform and chlorothene, is a chloroalkane with the chemical formula CH 3 CCl 3. It is an isomer of 1,1,2-trichloroethane. A colourless and sweet-smelling liquid, it was once produced industrially in large quantities for use as a solvent. [5]
The first Frenet-Serret formula holds by the definition of the normal N and the curvature κ, and the third Frenet-Serret formula holds by the definition of the torsion τ. Thus what is needed is to show the second Frenet-Serret formula. Since T, N, and B are orthogonal unit vectors with B = T × N, one also has T = N × B and N = B × T ...

Thermodynamics. In thermodynamics, the compressibility factor ( Z ), also known as the compression factor or the gas deviation factor, describes the deviation of a real gas from ideal gas behaviour. It is simply defined as the ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and pressure.
Etymology. The Mach number is named after the physicist and philosopher Ernst Mach according to a proposal by the aeronautical engineer Jakob Ackeret in 1929. The word Mach is always capitalized since it derives from a proper name, and since the Mach number is a dimensionless quantity rather than a unit of measure, the number comes after the word Mach; the second Mach number is Mach 2 instead ...
Estimates of world population by their nature are an aspect of modernity, possible only since the Age of Discovery.Early estimates for the population of the world date to the 17th century: William Petty, in 1682, estimated the world population at 320 million (current estimates ranging close to twice this number); by the late 18th century, estimates ranged close to one billion (consistent with ...
