operation directions essays

operation directions essays Anne Lamotts book Operating Instructions gives an outlook of a mildly disadvantaged woman. This journal is a chronicle of her son Sam's first year. She is fiercely self-deprived, funny and unafraid to talk about the dark side of parenting an infant: the fear, exhaustion, anger, emotional swings; that 4 a.m. inability to cope with the crying neediness of the baby. She questions her faith, which she cannot justify on a why she was pregnant, but still hopes that God loves and guides her the way a parent loves and guides a child. I am interested in surveying on how many new mothers have near manic-depressive, crazy feelings like the ones this author describes. She alternates hating the baby, wanting to throw him down the stairs, calling him "scum," etc.-with loving the baby so much she swoons, calling him breathtakingly beautiful, and being unable to imagine anything more wonderful ever happening to her. I got uncomfortable reading this book because the emotions were so raw and I could picture the child reading the book later in life and getting his feelings. The breakdown of a relationship, regardless of the reasons behind it, is probably one of the most emotionally draining experiences that we as adults face. This is often more traumatic where children's feelings are also involved. If one day I was going to have a baby, it would defiantly be with the man that I love. Love to me is assurance and dedication. It is extraordinarily wearisome for women to raise children themselves. My mother raised my brother and I herself, and as I got older she told me how big of a sacrifice it is as a single mother. She is a single parent barely able to pay the bills, however she has a tremendous support network of family, friends, in addition to the people of her church, all of who clearly love Sam and love her. The author's best friend Pammy is diagnosed with metastatic breast cancer. Where she, discovers the depth and inflection of love...

Dipole Moment Definition

Dipole Moment Definition A dipole moment is a measurement of the separation of two opposite electrical  charges. Dipole moments are a vector quantity. The magnitude is equal to the charge multiplied by the distance between the charges and the direction is from negative charge to positive charge: ÃŽ ¼ q  · r where ÃŽ ¼ is the dipole moment, q is the magnitude of the separated charge, and r is the distance between the charges. Dipole moments are measured in the SI units of coulomb ·meters (C m), but because the charges tend to be very small in magnitude, the historical unit for a dipole moment is the Debye. One Debye is approximately 3.33 x 10-30 C ·m. A typical dipole moment for a molecule is about 1 D. Significance of the Dipole Moment In chemistry, dipole moments are applied to the distribution of electrons between  two bonded atoms. The existence of a dipole moment is the difference between polar and nonpolar bonds. Molecules with a net dipole moment are polar molecules. If the net dipole moment is zero or very, very small, the bond and molecule are considered to be nonpolar. Atoms that have similar electronegativity values tend to form chemical bonds with a very small dipole moment. Example Dipole Moment Values The dipole moment is dependent on temperature, so tables that list the values should state the temperature. At 25 °C, the dipole moment of cyclohexane is 0. It is 1.5 for chloroform and 4.1 for dimethyl sulfoxide. Calculating the Dipole Moment of Water Using a water molecule (H2O), its possible to calculate the magnitude and direction of the dipole moment. By comparing the electronegativity values of hydrogen and oxygen, there is a difference of 1.2e for each hydrogen-oxygen chemical bond. Oxygen has a higher electronegativity than hydrogen, so it exerts a stronger attraction on the electrons shared by the atoms. Also, oxygen has two lone electron pairs. So, you know the dipole moment must point toward the oxygen atoms. The dipole moment is calculated by multiplying the distance between the hydrogen and oxygen atoms by the difference in their charge. Then, the angle between the atoms is used to find the net dipole moment. The angle formed by a water molecule is known to be 104.5 ° and the bond moment of the O-H bond is -1.5D. ÃŽ ¼ 2(1.5)cos(104.5 °/2) 1.84 D
