Databases are structured collections of data that enable efficient retrieval, insertion, updating, and deletion of information. They serve as the foundation for various applications, from simple contact lists to complex enterprise systems. Key concepts include tables, which organize data into rows and columns; relationships, which define connections between tables; and SQL (Structured Query Language), used to interact with databases by querying and manipulating data.

At the same time that the Civil Rights Movement brought increasing opportunities for blacks, the United States liberalized its immigration policy. While the broadening of the United States's borders to non-European immigrants fits with a black political agenda of social justice, recent waves of immigration have presented a dilemma for blacks, prompting ambivalent or even negative attitudes toward migrants. What has an expanded immigration regime meant for how blacks express national attachment?

In 1869, a great mystery was born. As astronomers observed a total solar eclipse, for the first time they saw the faint glow of the solar corona, the sun's outer atmosphere. Measurements of a previously unknown wavelength that made up this solar light sparked hot debate among scientists, but it was another 60 years before they discovered that this wavelength was in fact iron being burned at a staggering three million degrees Celsius. With the sun's surface only 6,000 degrees, this shouldn't be possible.

Haptics, or haptic sensing, refers to the ability to identify and perceive objects through touch. This is active touch, involving exploration of an object with the hand rather than the passive sensing of a vibration or force on the skin. The development of new technologies, including prosthetic hands and tactile surfaces for flat screen displays, depends on our knowledge of haptics. In this volume in the MIT Press Essential Knowledge series, Lynette Jones offers an accessible overview of haptics, or active touch sensing, and its applications.

The Supreme Court's decisions on constitutional rights are well known and much talked about. But individuals who want to defend those rights need something else as well: access to courts that can rule on their complaints. And on matters of access, the Court's record over the past generation has been almost uniformly hostile to the enforcement of individual citizens' constitutional rights.

Since FDR, the US healthcare system has been mired in politics and policy. All the while it has only increased in complexity and cost. Today half of all personal bankruptcies are attributable to healthcare costs. Many community hospitals are barely getting by with single digit profit margins. With a system teetering on the edge of a systemic crisis, we need to turn to a brand-new approach to rescue the US healthcare system.

A clock hangs over the head of every mortal. Counting down to the inescapable day that the Goddess of Death claims them. That is the way of the world. The natural cycle of mortals. The Gods, however, were said to live for forever. To exist so far outside of the natural laws of the universe that even their crimes can't be punished. But Knell Coba, at great cost, realizes this is nothing but another lie.
