Compact Fluorescent Lamps In Focus

Energy savings

CFLs use 70 to 80 percent less energy than incandescent bulbs. The typical incandescent lamp wastes 90 percent of the energy it uses since it produces heat rather than light. A 100-watt incandescent lamp may be replaced with a 20 to 23-watt CFL. Although CFLs may appear different than the common incandescent bulbs, CFLs fit most standard fixtures found in homes today. The screw-in base is the same for both lamps.

Long Life

CFLs last approximately 6,000 tto 10,000 hours. This is 8 to 13 times longer than the life of an incandescent lamp with an expected life of 750 to 1,000 hours.

Warm Light

Most CFLs have improved color rendition. The light is of a warm tone that is almost identical to that of an incandescent lamp. Most people can't tell the difference.

Julian Calendar

the calendar introduced by Julius Caesar. Based on a year of 365.25 days, it remains the calendar in use today although it is modified.

«««««««««««««««««««

The Julian calendar, a reform of the Roman calendar, was introduced by Julius Caesar in 46 BC, and came into force in 45 BC (709 ab urbe condita). It was chosen after consultation with the astronomer Sosigenes of Alexandria and was probably designed to approximate the tropical year, known at least since Hipparchus. It has a regular year of 365 days divided into 12 months, and a leap day is added to February every four years. Hence the Julian year is on average 365.25 days long.

The Julian calendar remained in use into the 20th century in some countries as a national calendar, but it has generally been replaced by the Gregorian calendar introduced by Pope Gregory XIII in 1582. It is still used by the Berber people of North Africa, on Mount Athos, and by many national Orthodox churches. Orthodox Churches no longer using the Julian calendar typically use the Revised Julian calendar rather than the Gregorian calendar.

The notation "Old Style" (OS) is sometimes used to indicate a date in the Julian calendar, as opposed to "New Style" (NS), which either represents the Julian date with the start of the year as 1 January or a full mapping onto the Gregorian calendar. This notation is used in reference to dates from tsarist Russia (the country did not switch to the Gregorian calendar until 1918).

Radar

(radio detection and ranging) the use of radio waves to discover the presence and distance of an object. Radar is used in the navigation of aircraft, ships, missiles and satellites.

_________________

Radar is an object detection system that uses electromagnetic waves to identify the range, altitude, direction, or speed of both moving and fixed objects such as aircraft, ships, motor vehicles, weather formations, and terrain. The term RADAR was coined in 1941 as an acronym for RAdio Detection And Ranging. The term has since entered the English language as a standard word, radar, losing the capitalization. Radar was originally called RDF (Radio Direction Finder, now used as a totally different device) in the United Kingdom, in order to preserve the secrecy of its ranging capability

Palaeogeography

the study of the physical geography at periods in the past.

Taken from Dictionary of Science

___________________________________________________________

Palaeogeography (also spelled paleogeography) is the study of what the geography was in times past. It is most often used about the physical landscape, although nothing excludes its use in reference to the human or cultural environment. If the topic is landforms it could also be called paleogeomorphology.

In petroleum geology the term paleogeographic analysis is used for the detailed study of sedimentary basins, since the ancient geomorphological environments of the Earth's surface are preserved in the stratigraphic record. Paleogeographers also study the sedimentary environment associated with fossils to aid in the understanding of evolutionary development of extinct species. The reconstruction of prehistoric continents and oceans depends on paleogeographic evidence. Thus paleogeography provides critical evidence for the development of continental drift and current plate tectonic theories. For example, knowledge of the shape and latitudinal location of supercontinents such as Pangaea and ancient oceans such as Panthalassa result from paleogeographic studies.

Not to be confused with palaeography.
