"Aint I A Woman": Reminiscences of Sojourner Truth Speaking
Isabelle Van Wagenen was born enslaved in New York State and became a well-known abolitionist speaker under the name Sojourner Truth after gaining her freedom in 1827. She moved to New York City where she engaged in evangelical and other reform activities; at various points she also lived in several utopian communities. Truth supported herself by traveling and speaking on abolitionist and women's rights subjects, taking the name Sojourner Truth in 1843. She often faced opposition at her speaking

"A Man's Thanksgiving": A Hymn to the God of Business
President Calvin Coolidge captured the spirit of the 1920s when he announced in a speech before the Society of American Newspaper Editors that "the chief business of the American people is business." Coolidge's aphorism revealed the centrality of commerce to the nation and its culture in the 1920s, even while it concealed some of the wrenching cultural changes required to accommodate a commercial civilization. An even more forceful publicist for the view that business and spirituality were compa

"A Little Standing Army in Himself": N. A. Jennings Tells of the Texas Rangers, 1875
The Treaty of Guadalupe Hidalgo in 1848 brought an enormous chunk of Mexico to the United States. This added to the territory obtained by the annexation of Texas in 1845, but more than just territory was added. More than 75,000 Spanish-speaking residents became U.S. citizens, but the struggle to achieve that citizenship was long and often unsuccessful. Mexican-Americans lost political power and civil liberties quickly in Texas. Justice was hard to secure and the ranching country of South Texas b

"A Foreigner in My Own Land": Juan Nepomuceno Seguin Flees Texas, 1842
Few Anglos lived in San Antonio after the Texas Revolution of 1835-36 and Tejanos (Texas-Mexicans) continued their rule. Juan Nepomuceno Seguin was born into a prominent tejano family and had close ties with Stephen Austin, leader of the first American settlers in Texas. He became mayor or alcade at an early age and fought on the Anglo side with the coming of Texas' revolt against Mexico. However, his political situation increasingly became fragile because of the changing balance of power and An

The Microevolution of Mathematical Knowledge: The Case of Randomness
In this article, we explore the growth of mathematical knowledge and in particular, seek to clarify the relation between abstraction and context. Our method is to gain a deeper appreciation of the process by which mathematical abstraction is achieved and the nature of abstraction itself, by connecting our analysis at the level of observation with a corresponding theoretical analysis at an appropriate grain size. In this article, we build on previous work to take a further step toward constructin

Break the Science Barrier - Richard Dawkins - Part 1 of 3
Break the Science Barrier follows the Oxford Biologist Richard Dawkins as he meets with people who have experienced the wonders of science first-hand. We meet the astronomer who first discovered pulsars, the geneticist who invented DNA fingerprinting, a scientist who discovered a protein that causes cancer, and others. Dawkins interviews famous admirers of science such as Douglas Adams and David Attenborough, and asks them why science means so much to them. We also see how dangerous ignorance of
