To improve the efficiency of the lamp, the filament usually consists of multiple coils of coiled fine wire, also known as a 'coiled coil'. For a 60-watt 120-volt lamp, the uncoiled length of the tungsten filament is usually 22.8 inches (580 mm), and the filament diameter is 0.0018 inches (0.046 mm). The advantage of the coiled coil is that evaporation of the tungsten filament is at the rate of a tungsten cylinder having a diameter equal to that of the coiled coil. The coiled-coil filament evaporates more slowly than a straight filament of the same surface area and light-emitting power. As a result, the filament can then run hotter, which results in a more efficient light source, while reducing the evaporation so that the filament will last longer than a straight filament at the same temperature.
What is the typical diameter of the filament on a 60-watt bulb?
0.0018 inches

As a protector and founder, Apollo had the epithets Alexicacus (/lkskeks/ -LEK-si-KAY-ks; , Alexikakos, literally "warding off evil"), Apotropaeus (/ptrpis/ -POT-r-PEE-s; , Apotropaios, from , "to avert"), and Epicurius (/pkjris/ EP-i-KEWR-ee-s; , Epikourios, from , "to aid"), and Archegetes (/rkdtiz/ ar-KEJ--teez; , Arkhegetes, literally "founder"), Clarius (/klris/ KLARR-ee-s; , Klarios, from Doric , "allotted lot"), and Genetor (/dntr/ JEN-i-tr; , Genetor, literally "ancestor"). To the Romans, he was known in this capacity as Averruncus (/vrks/ AV-r-RUNG-ks; from Latin averruncare, "to avert"). He was also called Agyieus (/da.jus/ -GWEE-ews; , Aguieus, from , "street") for his role in protecting roads and homes; and Nomius (/nomis/ NOH-mee-s; , Nomios, literally "pastoral") and Nymphegetes (/nmfdtiz/ nim-FEJ-i-teez; , Numphegetes, from , "Nymph", and , "leader") for his role as a protector of shepherds and pastoral life.
What word literally mens "ancestor?"
Genetor

The MPEG-1 standard does not include a precise specification for an MP3 encoder, but does provide example psychoacoustic models, rate loop, and the like in the non-normative part of the original standard. At present, these suggested implementations are quite dated. Implementers of the standard were supposed to devise their own algorithms suitable for removing parts of the information from the audio input. As a result, there are many different MP3 encoders available, each producing files of differing quality. Comparisons are widely available, so it is easy for a prospective user of an encoder to research the best choice. An encoder that is proficient at encoding at higher bit rates (such as LAME) is not necessarily as good at lower bit rates.
