Cultural depictions of Alan Turing, the British mathematician and computer scientist, span various media, including film, literature, theater, and art. Turing is best known for his contributions to computer science and artificial intelligence, as well as his crucial role in breaking the Enigma code during World War II.

Mileva Marić (1875-1948) was a Serbian physicist and mathematician, known primarily for her association with Albert Einstein, including their relationship and collaboration during his early scientific work. Over the years, Marić has been depicted in various cultural forms, ranging from literature to film and theater.

Arithmetic dynamics is a field of mathematics that combines elements of number theory and dynamical systems. It primarily studies the behavior of sequences of numbers defined by iterative processes, especially those arising from polynomial or rational functions.

Algebraic varieties are fundamental objects of study in algebraic geometry, a branch of mathematics that combines algebra, particularly commutative algebra, with geometric concepts. An algebraic variety is, broadly speaking, a geometric object defined as the solution set of a system of polynomial equations.

Arithmetic is a branch of mathematics that deals with the study of numbers and the basic operations performed on them. The fundamental operations of arithmetic include: 1. **Addition (+)**: Combining two or more quantities to obtain a total. 2. **Subtraction (−)**: Determining the difference between two quantities by taking one away from another. 3. **Multiplication (×)**: Repeated addition of a number a specified number of times.

In mathematics, a proportion is an equation that states that two ratios are equal. Ratios compare two quantities and can be expressed in several ways, such as fractions, decimals, or percentages. A proportion can be represented in the following general form: \[ \frac{a}{b} = \frac{c}{d} \] In this equation, \( \frac{a}{b} \) and \( \frac{c}{d} \) are both ratios.

An Active Cavity Radiometer (ACR) is an instrument used to measure thermal radiation and is specifically designed to obtain precise measurements of the intensity of radiation from various sources. It operates based on the principle of measuring the temperature change caused by the absorption of radiation within a cavity. The essential components of an active cavity radiometer typically include: 1. **Cavity**: This is a thermally isolated chamber that absorbs incoming radiation.

Actuarial science is a discipline that applies mathematical and statistical methods to assess risk in insurance, finance, and other industries. It involves the evaluation of financial risks using mathematics, statistics, and financial theory, particularly in relation to uncertain future events. Actuaries use their expertise to analyze data and develop models that help organizations make informed decisions regarding risk management and financial planning. This includes roles such as: 1. **Insurance**: Designing insurance policies, calculating premiums, and assessing the likelihood of claims.
