question: When Joan gave birth to the first boy in her family in three generations, she and her husband were overjoyed. So were her parents. Joan expected her elder sister, Sally, to be just as delighted as them. Joan had always admired Sally--the beauty and the star of the family--and felt happy about her achievements.

But since the baby's arrival, the sisters have become distant. Joan feels hurt for Sally seems completely uninterested in her baby. Sally, who has no children, claims that her younger sister "acts as if no one ever had a baby before."

Neither Sally nor Joan understands that the real cause of the current coldness is that their family roles have suddenly changed to the opposite. Finally Joan seems to be better than her elder sister--and Sally doesn't like it! Their distance may be temporary, but it shows that childhood competition don't fade easily as ages grow. It can remain powerful in relationships throughout life.

In a study of the University of Cincinnati, 65 men and women between ages 25 and 93 were asked how they felt about their brothers and sisters. Nearly 75 percent admitted having hidden competitive feelings. In a few cases, these emotions were so strong as to have affected their entire lives.

Many adult brothers and sisters are close, supportive--yet still tend to compete. Two brothers I know turn into killers when on opposite sides of a tennis net. Off the court, they are the best of friends. My own younger sister can't wait to tell me when I've put on weight. However, she's a terrible cook and that pleases me; I tease her when she comes to dinner. Happily, despite these small failings, we have been an important resource for each other.

In between the very competitive and the generally supportive children lie those who say that no friendship should survive. _ . Why do these puzzling, unproductive, often painful relationships continue to exist?

question: Yale University is an American private Ivy League research university in New Haven, Connecticut. Founded in 1701 in Saybrook Colony as the Collegiate School, the University is the third-oldest institution of higher education in the United States. The school was renamed Yale College in 1718 in recognition of a gift from Elihu Yale, who was governor of the British East India Company. Established to train Congregationalist ministers in theology and sacred languages, by 1777 the school's curriculum began to incorporate humanities and sciences. In the 19th century the school incorporated graduate and professional instruction, awarding the first Ph.D. in the United States in 1861 and organizing as a university in 1887.

Yale is organized into fourteen constituent schools: the original undergraduate college, the Yale Graduate School of Arts and Sciences, and twelve professional schools. While the university is governed by the Yale Corporation, each school's faculty oversees its curriculum and degree programs. In addition to a central campus in downtown New Haven, the University owns athletic facilities in western New Haven, including the Yale Bowl, a campus in West Haven, Connecticut, and forest and nature preserves throughout New England. The university's assets include an endowment valued at $25.6 billion as of September 2015, the second largest of any educational institution.The Yale University Library, serving all constituent schools, holds more than 15 million volumes and is the third-largest academic library in the United States.

question: The radian is the standard unit of angular measure, used in many areas of mathematics. The length of an arc of a unit circle is numerically equal to the measurement in radians of the angle that it s; one radian is just under 57.3 degrees (expansion at ). The unit was formerly an SI supplementary unit, but this category was abolished in 1995 and the radian is now considered an SI derived unit.

Separately, the SI unit of solid angle measurement is the steradian.

The radian is represented by the symbol rad. An alternative symbol is , the superscript letter c (for "circular measure"), the letter r, or a superscript , but these symbols are infrequently used as it can be easily mistaken for a degree symbol () or a radius (r). So, for example, a value of 1.2 radians could be written as 1.2rad, 1.2r, 1.2, or 1.2, or 1.2.

Radian describes the plane angle subtended by a circular arc as the length of the arc divided by the radius of the arc. One radian is the angle subtended at the center of a circle by an arc that is equal in length to the radius of the circle. More generally, the magnitude in radians of such a subtended angle is equal to the ratio of the arc length to the radius of the circle; that is, , where "" is the subtended angle in radians, "s" is arc length, and "r" is radius. Conversely, the length of the enclosed arc is equal to the radius multiplied by the magnitude of the angle in radians; that is, .
