Examples of Black Star Line in the following topics:
-
Marcus Garvey
- He founded the Universal Negro Improvement Association and African Communities League (UNIA-ACL), as well as the Black Star Line, part of the Back-to-Africa movement that promoted the return of the African diaspora to their ancestral lands.
- He visited Tuskegee and afterward met a number of black leaders.
- On June 27, 1919, the Black Star Line of Delaware was incorporated by the members of UNIA, with Garvey as President.
- By September, the Black Star Line obtained its first ship, rechristened as the S.S.
- Run by a group called the Friends of Negro Freedom, the campaign pressed the federal government to investigate the Black Star Line.
-
The Rise of Garveyism
- Marcus Garvey, a political leader and orator, was a proponent of black nationalism and Pan-Africanism.
- He founded the Universal Negro Improvement Association and African Communities League (UNIA-ACL), and also founded the Black Star Line, part of the Back-to-Africa movement.
- Garvey visited Tuskegee, and afterward visited with a number of black leaders.
- On June 27, 1919, the Black Star Lineof Delaware was incorporated by the members of the UNIA, with Garvey as president.
- Convinced that blacks should have a permanent homeland in Africa, Garvey sought to develop Liberia.

Planck's Quantum Hypothesis and Black Body Radiation
- A black body emits radiation called black body radiation.
- A black body in thermal equilibrium (i.e. at a constant temperature) emits electromagnetic radiation called black body radiation.
- This equation explains the black body spectra shown below.
- Despite its simplicity, Planck's law describes radiation properties of objects (e.g. our body, planets, stars) reasonably well.
- Black line is a prediction of a classical theory for an object at 5,000K, showing catastropic discrepancy at shorter wavelengh.
-
Jackie Robinson
- Jackie Robinson was the first black Major League Baseball player in the United States.
- His athletic abilities prevailed despite the intense pressures caused by breaking the "color line. " Robinson won respect and became a symbol of black opportunity.
- His impressive running speed, powerful hitting, and strong fielding made Robinson a key player on a team with many stars.
- The Dodgers succeeded well with such black stars as Jackie Robinson, Roy Campanella, and Don Newcombe.
- Jackie Robinson was the first black Major League Baseball player in the United States

An Invitation
- Of course, many of the objects in Messier's catalogue are galaxies and clusters and therefore consist of stars.
- The Crab Nebula and its central neutron star, the Crab Pulsar, emit radiation across the electromagnetic spectrum, accelerate cosmic rays, harbour relativistic shocks and strong magnetic fields.
- Relating the spectral lines and their strengths to particular atoms are their abundances requires a detailed knowledge of the physics of atoms (Chap.8) and their transitions (Chap.9).
- As the gas cools subsequent to the supernova, it forms molecules (Chap.10) and eventually another generation of stars.
- Meanwhile in the centre of the supernova remnant the neutron star or black hole formed may accrete from the ejectra, the interstellar medium or a companion (Chap.13).

Yoruba Artwork in the transAfrican Context
- In the midst of the racial and cultural turmoil of the 1960s, a group of African-American artists endeavored to relate its artwork to the black masses.
- TransAfrican art is characterized by rhythmic use of lines, vibrant colors, bold patterns, motion, and often an emotional intensity.
- One of his key works, Victory in the Valley of Eshu (1970), depicts an elderly black couple holding what appears to be an eye-shaped pinwheel.
- The newly prominent element of shine, an aesthetic effect mimicking or displaying physical shine in order to reflect the bright, star-like quality of ordinary African Americans, is also visible in this piece.
- This effect achieves the celebration aspect of black art: an art that, as stated by Donaldson, defines, glorifies, and directs black peopleāan art for the people's sake.
-
American Art Deco Architecture
- Its architectural style emphasized curving forms, long horizontal lines, and sometimes nautical elements.
- Streamline Moderne was a concept first created by industrial designers, who stripped Art Deco design of its ornament in favor of the aerodynamic pure-line concept of motion and speed developed from scientific thinking.
- The Hecht Company Warehouse (Washington, D.C.) is a Streamline Moderne style building.The building uses glass block extensively, culminating in a twelve-pointed star-shaped cupola at the corner, which is illuminated at night.
- Black brick interspersed with glass block spells out "The Hecht Co" at the fifth floor.
-
Goya
- From royal portraits completed while he was court painter to the Spanish Crown; to political, evocative paintings that date from later in his life, Goya's work is renowned for its expressive line, color and brushwork as well as its distinct subversive commentary.
- It was here that he created his "Black Paintings", a number of intense works with themes of fear and madness.
- The themes expressed in Goya's "Black Paintings" perhaps reflect his own personal inner turmoil of his later life.
- 'Saturn Devouring His Son' is one work amongst Goya's 'Black Paintings. '

Problems
- What is the total about of energy released per gram of material as it falls from infinity to the surface of a neutron star?
- How many grams of material would have to fall each second on the neutron star to generate an Eddington luminosity through accretion?
- What is the total energy of a ring at a distance r from the central black hole of mass $M$?
- As the ring shrinks mass is moving toward the black hole.
- The accretion rate is determined by the evolution of the orbit of the black hole with its companion, so it doesn't know about the Eddington limit of the black hole.

Introduction: The several faces of power
- Consider the three simple graphs of networks in figures 10.1, 10.2, and 10.3, which are called the "star," "line," and "circle."
- What about the position of A in the line network?
- Is being at the end of the line an advantage or a disadvantage?
- In the star network, Actor A has degree six, all other actors have degree one.
- In the line network, matters are a bit more complicated.
