Q: A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle, defined so that a full rotation is 360 degrees. 

It is not an SI unit, as the SI unit of angular measure is the radian, but it is mentioned in the SI brochure as an accepted unit. Because a full rotation equals 2 radians, one degree is equivalent to radians. 

The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year. Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day. Some ancient calendars, such as the Persian calendar, used 360 days for a year. The use of a calendar with 360 days may be related to the use of sexagesimal numbers. 

Another theory is that the Babylonians subdivided the circle using the angle of an equilateral triangle as the basic unit and further subdivided the latter into 60 parts following their sexagesimal numeric system. The earliest trigonometry, used by the Babylonian astronomers and their Greek successors, was based on chords of a circle. A chord of length equal to the radius made a natural base quantity. One sixtieth of this, using their standard sexagesimal divisions, was a degree.

Q: Dr.Michael Prager, a leading Botox expert, said that a growing number of women are developing something called "computer face".He also mentioned that professionals who worked long hours in front of a screen were ending up with saggy jowls , "turkey neck" and deep-set wrinkles on their forehead and around their eyes. 

The Botox expert said that, of all his clients, office workers were most likely to show premature signs of ageing."If you are one of the unfortunate people who frown while you are concentrating on the screen then, over time, you will inevitably end up with frown lines," Dr.Prager said."What is perhaps more surprising is the number of women with saggy jowls because they are sitting in one position for so long.If you spend most of the time looking down then the neck muscles shorten and go saggy, eventually giving you a second neck." 

Dr.Prager, who has a practice near Harley Street in London, said he encourages his clients to put a mirror next to their computer so they can see if they are frowning at the screen."When people are stressed or thinking hard about something, then they will often put on a 'grumpy face' without even knowing what they are doing.When my clients put a mirror next to their desk, they are often shocked by the angry, frowning face which stares back at them." 

He said, "The women I am seeing at the moment have only been using computers at work for the last decade or so.But women in their 20s have grown up with them and use them for every single task.I think the problem is going to become much, much worse.In another ten years, they could be looking quite awful." 

Dr.Prager said there were several simple steps which could avoid "computer face" such as regular screen breaks and stretching the neck muscles.And, of course, there was always Botox.He said that, after a couple of sessions of Botox, the habit of "grumpy face" could be broken.

Q: Joint Base Lewis-McChord, Washington (CNN) -- It was the middle of the night in southern Afghanistan's Panjwai district when Haji Naim says he was awakened by the sound of barking dogs and gunshots. 

Moments later, a man clothed in U.S. military fatigues and a T-shirt burst through the door of Naim's home and opened fire, hitting him in the neck, Naim testified early Saturday at a hearing for an Army soldier accused in a mass killing of Afghan civilians. 

"I said 'What are you doing? What are you doing?' Naim told the court at Joint Base Lewis-McChord, near Tacoma, Washington, during a live satellite uplink from a base in Kandahar, Afghanistan. 

"He didn't say anything ...He just started shooting." 

Afghan anger kept U.S. agents from killing scene 

Naim and his two sons were among the survivors of the March 11, 2012, rampage that military prosecutors allege was carried out by Army Staff Sgt. Robert Bales. 

Naim's testimony came amid the fifth day of an evidentiary hearing to determine whether there is enough evidence to support the military's case against Bales, who faces 16 counts of premeditated murder and six counts of attempted murder in the predawn attack. 

The outcome of the Article 32 hearing will determine whether Bales, 39, is court-martialed, and whether he will face the death penalty. 

Bales has not entered a plea in the case, though his attorneys have said Bales suffers from post-traumatic stress disorder and suffered a traumatic brain injury during a prior deployment to Iraq.
