Interesting Facts About Maya Angelou

Interesting Facts About Maya Angelou Thanks to her award-winning writing, Maya Angelou was internationally known decades before her death at age 86 in 2014. Despite her fame and her many memoirs, many interesting details about her life remain widely unknown to the public. Familiarize yourself with the life and work of Maya Angelou with this list of interesting facts about her life. Family Life She may have risen to fame as â€Å"Maya Angelou,† but she was not born with that first name or with that surname. Instead, Angelou was born Marguerite Annie Johnson on April 4, 1928, in St. Louis. â€Å"Maya† derives from a childhood nickname and Angelou is a shortened version of Angelopulos, the surname of a Greek sailor the writer married in 1952.It’s uncertain how many times Angelou married, the New York Times reported in her obituary. â€Å"Throughout her life, she was cagey about the number of times she married- it appears to have been at least three- for fear, she said, of appearing frivolous,† the Times noted.Although Angelou married a number of times, she bore just one child, a son named Guy Johnson. She gave birth to him at the age of 16. He was the product of a brief romance Angelou had with a neighborhood boy in Northern California. Career During her young adulthood, Angelou became the first black woman to work as a streetcar conductor in San Francisco, according to the Times.Although Angelou stood 6 feet tall, she managed to carve out a career as a dancer as a young woman. She even danced with the likes of Alvin Ailey.Angelou appeared in a number of theatrical productions, earning a Tony nomination for her role in 1973’s â€Å"Look Away,† a play about Mary Todd Lincoln and her seamstress. Friendship With Prominent African Americans Angelou stopped celebrating her birthday because the Rev. Martin Luther King Jr., a friend of hers, was assassinated on that day. Instead of celebrating her birthday, Angelou sent flowers to King’s widow, Coretta, according to Biography.com. In addition to King, Angelou was friends with a number of other prominent African Americans, including James Baldwin and Malcolm X, the New York Times reported. Literary Career Angelou rose to fame after the publication of her 1969 memoir, I Know Why The Caged Bird Sings. That book made history, as it marked the first time an autobiography by an African-American woman became a best-seller in the United States.Caged Bird was far from Angelou’s only memoir. The writer followed that effort up with Gather Together in My Name (1974), Singin’ and Swingin’ and Gettin’ Merry Like Christmas (1976), The Heart of a Woman (1981), All God’s Children Need Traveling Shoes (1986) and A Song Flung Up to Heaven (2002). Moreover, in 2013, Angelou’s memoir about her relationship with her mother, Mom Me Mom, debuted.Despite the fact that she excelled as a writer above all else, Angelou said that the craft did not come easily to her. In 1990, she told the Paris Review, â€Å"I try to pull the language into such a sharpness that it jumps off the page. It must look easy, but it takes me forever to get it to look so easy. Of course, ther e are those critics- New York critics as a rule- who say, Well, Maya Angelou has a new book out and of course it’s good but then she’s a natural writer. Those are the ones I want to grab by the throat and wrestle to the floor because it takes me forever to get it to sing. I work  at the language.†Ã‚   More About Maya Angelou A globetrotter, Angelou spoke a number of languages, including French, Italian, Spanish, Arabic, and the West African language Fanti, according to her website.Angelou had a seafood allergy. Apparently, it was so severe that she requested people not to eat seafood prior to meeting with her.

Specific Heat Capacity Definition

Specific Heat Capacity Definition Specific Heat Capacity Definition Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass. The specific heat capacity of a material is a physical property. It is also an example of an extensive property since its value is proportional to the size of the system being examined.In ​SI units, specific heat capacity (symbol: c) is the amount of heat in joules required to raise 1 gram of a substance 1 Kelvin.   It may also be expressed as J/kg ·K. Specific heat capacity may be reported in the units of calories per gram degree Celsius, too. Related values are molar heat capacity, expressed in J/mol ·K, and volumetric heat capacity, given in J/m3 ·K. Heat capacity is defined as the ratio of the amount of energy transferred to a material and the change in temperature that is produced: C Q / ΔT where C is heat capacity, Q is energy (usually expressed in joules), and ΔT is the change in temperature (usually in degrees Celsius or in Kelvin). Alternatively, the equation may be written: Q CmΔT Specific heat and heat capacity are related by mass: C m * S Where C is heat capacity, m is mass of a material, and S is specific heat. Note that since specific heat is per unit mass, its value does not change, no matter the size of the sample. So, the specific heat of a gallon of water is the same as the specific heat of a drop of water. Its important to note the relationship between added heat, specific heat, mass, and temperature change does not apply during a phase change. The reason for this is because heat that is added or removed in a phase change does not alter the temperature. Also Known As: specific heat, mass specific heat, thermal capacity Specific Heat Capacity Examples Water has a specific heat capacity of 4.18 J (or 1 calorie/gram  °C). This is a much higher value than that of most other substances, which makes water exceptionally good at regulating temperature. In contrast, copper has a specific heat capacity of 0.39 J. Table of Common Specific Heats and Heat Capacities This chart of specific heat and heat capacity values should help you get a better sense of the types of materials that readily conduct heat versus those which do not. As you might expect, metals have relatively low specific heats.
