Application of Normal mode calculations in optical spectroscopy | Phym 221 – Assignment 4 1. Introduction Normal modes are used to describe the different vibration motion in molecules. There are different types of modes for molecules in different motions and each has a certain symmetry associated with it. 2. Overview of Normal Modes Generally‚ normal modes are independent atoms in a molecule that are in motion such that they do not disturb the motion of the other molecules. Normal modes as implied

Normal Distribution It is important because of Central Limit Theorem (CTL)‚ the CTL said that Sum up a lot of i.i.d random variables the shape of the distribution will looks like Normal.

However‚ someone gives an idea that looks stupid but actually very brilliant by multiply two of them. reminds the function of circle which we can replace them to polar coordinate Thus Mean

The Pressure to Conform in Our Society When I think of how I have been pressured to conform throughout my life the first thing that comes to mind is peer pressure. I have known peer pressure‚ but‚ upon further reflection‚ I realize that for many years‚ I was fairly sheltered from negative peer pressure. There have been two groups that have consistently put more pressure on me to conform than my peers ever did. I have had more pressure to conform though out my life from my family and school administrators

Today‚ it cannot be denied that the liberation of the women (will be better to change to the women’s liberation) from domestic duties and subservient status has actually brought them an independently social equal position or superior to that of men.

There are many tactics to get a point across. Some will use violent ways and others will choose to do peaceful resistance. Peaceful resistance positively impacts a free society. Martin Luther King is an example. Martin Luther King JR‚ definitely made an impact and got his point across. Many people joined his peaceful protesting and he got a lot of respect even today.

I believe that it is a woman ’s right to choose whether or not she shall have a child. The issue of abortion is widely disputed in our nation‚ and is considered taboo because it has to do with sex. Many people are against abortion because of religious or moral beliefs. However‚ most of the people who argue against abortion have no adopted children. The reality is this: if an unwanted child is born into this world‚ they will suffer a great deal throughout their life. Also‚ the abortion is performed

Normal Distribution Normal distribution is a statistics‚ which have been widely applied of all mathematical concepts‚ among large number of statisticians. Abraham de Moivre‚ an 18th century statistician and consultant to gamblers‚ noticed that as the number of events (N) increased‚ the distribution approached‚ forming a very smooth curve. He insisted that a new discovery of a mathematical expression for this curve could lead to an easier way to find solutions to
