Garrett Cullity is a philosopher known for his work in moral philosophy, particularly in the areas of ethics and philosophy of action. He has contributed to discussions on the nature of moral responsibility, the justification of moral claims, and the implications of moral values on human behavior. Cullity is often associated with analyses of moral reasons and ethical theories, exploring how they apply to practical situations.

Anne Greenbaum is a notable figure in the field of applied mathematics, particularly known for her work in numerical analysis and scientific computing. She has contributed to various areas, including numerical methods for differential equations and numerical linear algebra.

An antibonding molecular orbital is a type of molecular orbital that is formed when atomic orbitals combine in a way that leads to a destabilizing interaction between the bonded atoms. These orbitals are higher in energy than the atomic orbitals from which they are formed.

The anti-nuclear movement in India is a social and political movement that opposes the development and proliferation of nuclear energy and nuclear weapons in the country. This movement encompasses a variety of local and national groups, activists, and organizations that have raised concerns about the environmental, health, and safety implications of nuclear projects.

Anti-sidereal time is a concept related to the measurement of time based on the celestial positions of stars. While sidereal time is defined based on the Earth's rotation relative to distant stars, anti-sidereal time is essentially the inverse concept.

Randomness has a wide array of applications across various fields and disciplines. Here are some of the key applications: 1. **Cryptography**: Random numbers are essential for secure encryption methods. They are used to generate keys, nonces, and initialization vectors, ensuring the security of communications and data. 2. **Statistics**: Random sampling is used to obtain representative samples from a population, critical for surveys and experiments to ensure unbiased results and valid conclusions.
