In celestial mechanics, the mean anomaly is a parameter that defines the position of a body that is moving in a Kepler orbit. It is defined as the time since the last periapsis (closest approach to the central body) times 2π / T, where T is the duration of a full orbit. The mean anomaly increases uniformly from 0 to 2π radians during each orbit. However, it does not have any simple interpretation as a geometric angle; it is merely time measured in radians. Due to Kepler's second law, however, the mean anomaly is proportional to the area swept by the focus-to-body line since the last periapsis. The mean anomaly is usually denoted by the letter M, and is also given by the formula
where a is the length of the orbit's semi-major axis and μ is the standard gravitational parameter. The mean anomaly is one of three angular parameters ("anomalies") that define a position along an orbit; the other two being the eccentric anomaly and the true anomaly. From Wikipedia under the
GNU Free Documentation License Question about anomaly scan? Q. Hi im going for my anomaly scan when i am 23 weeks. I have just been told for this i have my ultrasound scan first and then 3D. Does this mean i get to see the baby like its skin and everything kind of like a 4d scan? Im a little confused :S Thanks Asked by Had healthy baby boy 28/06/09 :D - Fri Jan 30 08:49:38 2009 - - 2 Answers - 0 Comments A. 4-d is the baby in motion (aka the video footage of 3-d u/s). 3-d is the orange looking ultra sound pictures (link below). It's done with the same machine as the 2-d black and white u/s pics. They just press a different button to make it show up 3-d/4-d. You'll see skin but if the tech zooms in too far, you might see bone and missing features. It's pretty wild. Ultrasounds work but bouncing sound off of an object. By zooming in, sound is bounced closer to the object. Like slicing bread. Email me and I'll send you pics from my 3-d scan. Answered by Corn_Flake - Fri Jan 30 08:59:20 2009 Is this a misleading way to present Arctic temperature anomaly data? Q. Below is a link to a GISS global temperature anomaly map. It highlights a very large area of the arctic displaying a temperature anomaly of between +4 and +7.2 deg C. But is this a fair representation of the data? Imagine you are at the North Pole, and there is actually a pole there. If you put your hand on the pole and walk around you would circumnavigate the pole in about 8 paces. If you were to circumnavigate the earth at the equator it would take you approximately 50,000,000 paces. In the map, the top edge represents about 8 paces, but the middle of the map (at the equator) represents 50 million paces. In the pictorial representation both are given the same emphasis. For the near polar arctic region, data from only about 6… [cont.] Asked by DaveH - Wed May 19 02:52:02 2010 - - 6 Answers - 2 Comments A. To a scientist, no. To the public, Yes.

Q. "Parents of a newborn whose condition involves moderate retardation refuse permission for a simple surgery that would repair a physical anomaly inconsistent with continued life, and they let the infant die." Does this mean that the surgery may not help at all or that without it death is inevitable? Asked by Cynthia G - Sat Feb 16 15:10:45 2008 - - 2 Answers - 0 Comments A. Not know what came before this or not. What I read is that the child has some form of physical retardation. Since the surgery is for a physical anomaly the the surgery may not have helped save the child.
