Parsec: Is a unit of measure equal to just slightly more than 3.25 light years (about 19 trillion miles). Parsec is a combination of two words, parallax and arcsecond.

So then what is a parallax? It is the perceived movement of an object traveling through space as seen from a fixed position on earth. For example if you took a pen and held it in front of your face, and quickly opened and closed your left eye and then right eye, the perceived horizontal movement (or jump) of the pen is a parallax. The further the object the smaller the parallax, the closer the object the greater the parallax. This is used to measure the distance to stars and is preformed using photographs of stars from an observatory. Six months later when the Earth has traveled halfway around its orbit a second photograph is taken. By measuring the distance the object "jumped" scientists can calculate the arc seconds of the parallax to reveal the distance.

What is an arc second? Think of it as a ruler. If you drew a circle and bisected the circle evenly by 180 lines…they would form 360 equal sections. Each section is an arc. Now further bisect each arc with 60 evenly spaced lines..Arc minutes. Now bisect each arc minute with 60 more lines..you get arc seconds. Think of it as going from meters, to centimeters to millimeters.

Lacrosse, that was a surprise.


Why is the sky blue? The sky is blue because of a process called Rayleigh scattering. This process involves the scattering of light off of molecules in the atmosphere. When light moves through the atmosphere, most of its wavelengths are able to simply pass through esp longer wavelengths. Shorter wavelengths, however, are less capable of passing through and are instead absorbed by the gas molecules in the atmosphere. Gas molecules are absorb all colors of light.The sky is blue because blue light is more readily absorbed, while other wavelengths pass through easily.

There was a time when reading wasn't just for fags. And neither was writing. People wrote books and movies. Movies with stories, that made you care about whose ass it was and why it was farting. And I believe that time can come again!

Mood swings, tender breasts, a swollen abdomen, food cravings, fatigue, irritability and depression. If you experience some or all of these problems in the days before your monthly period, you may have premenstrual syndrome (PMS).

An estimated three of every four menstruating women experience some form of premenstrual syndrome. These problems are more likely to trouble women between their late 20s and early 40s, and they tend to recur in a predictable pattern. Yet the physical and emotional changes you experience with premenstrual syndrome may be more or less intense with each menstrual cycle.

Still, you don't have to let these problems control your life. In recent years, much has been learned about premenstrual syndrome. Treatments and lifestyle adjustments can help you reduce or manage the signs and symptoms of premenstrual syndrome.

For many women the signs and symptoms of premenstrual syndrome are an uncomfortable and unwelcome part of their monthly menstrual cycle. The most common physical and emotional signs and symptoms associated with premenstrual syndrome include:

Weight gain from fluid retention
Abdominal bloating
Breast tenderness
Tension or anxiety
Depressed mood
Crying spells
Mood swings and irritability or anger
Appetite changes and food cravings
Trouble falling asleep (insomnia)
Joint or muscle pain
Headache
Fatigue

Although the list of potential signs and symptoms is long, most women with premenstrual syndrome experience only a few of these problems.

For some women, the physical pain and emotional stress are severe enough to affect their daily routines and activities. For most of these women, symptoms disappear as the menstrual period begins.

But for some women with premenstrual syndrome, symptoms are so severe they're considered disabling. This form of PMS has its own psychiatric designation — premenstrual dysphoric disorder (PMDD). PMDD is a severe form of premenstrual syndrome with symptoms including severe depression, feelings of hopelessness, anger, anxiety, low self-esteem, difficulty concentrating, irritability and tension. A number of women with severe PMS may have an underlying psychiatric disorder.

Exactly what causes premenstrual syndrome is unknown, but several factors may contribute to the condition. Cyclic changes in hormones seem to be an important cause, because signs and symptoms of premenstrual syndrome change with hormonal fluctuations and also disappear with pregnancy and menopause.

Chemical changes in the brain also may be involved. One clue to the cause may be traced to fluctuations of serotonin, a brain chemical (neurotransmitter) that is thought to play a crucial role in mood states, especially depression. Insufficient amounts of serotonin may contribute to other symptoms of PMS, such as fatigue, food cravings and sleep problems.

Occasionally, some women with severe premenstrual syndrome have undiagnosed depression, though depression alone does not cause all of the symptoms associated with premenstrual syndrome. Stress also may aggravate some of the symptoms, but alone it isn't a cause.

Some PMS symptoms have been linked to low levels of vitamins and minerals. Other possible contributors to PMS include eating a lot of salty foods, which may cause fluid retention, and drinking alcohol and caffeinated beverages, which may cause mood and energy level disturbances.
