Contemporary plays can be considered modern in the sense that they reflect current societal issues, values, and cultural norms. They often incorporate modern technology, language, and themes that are relevant to today's audience. However, the term "modern" can also refer to a specific historical period in theater, typically the late 19th and early 20th centuries, so in that sense, contemporary plays may not be considered modern. Overall, the classification of contemporary plays as modern depends on the context and definition being used. **

Abstract Expressionism emerged in the 1940s in New York City and is considered the first specifically American movement to achieve international influence. It is characterized by its emphasis on spontaneous, gestural expression, often using non-traditional materials and techniques. Artists like Jackson Pollock, Willem de Kooning, and Mark Rothko were key figures in this movement, which aimed to convey emotions and the human experience through abstract forms. Abstract Expressionism is often seen as a response to the trauma of World War II and a reflection of the post-war era's existential angst and search for meaning. **

Abstract reason, according to Plato, refers to the ability of the human mind to grasp universal truths and concepts that exist beyond the physical world. Plato believed that these universal truths, such as justice, beauty, and goodness, exist in a separate realm of reality, which he called the world of forms or ideas. Abstract reason allows individuals to access this realm through philosophical contemplation and dialectic, enabling them to understand and pursue these universal truths in their lives. Plato's theory of abstract reason is foundational to his philosophy and has had a significant influence on Western thought. **

The formula for the sum of a geometric series is derived by considering the sum of the first n terms of the series. By multiplying the first term by the common ratio raised to the power of n-1, we can find the nth term of the series. Then, by subtracting the sum of the series up to the (n-1)th term from the sum up to the nth term, we can isolate the formula for the sum of the geometric series. This formula is S = a(1 - r^n) / (1 - r), where S is the sum of the series, a is the first term, r is the common ratio, and n is the number of terms. **

The term for the ability to explain abstract and complex things in English is "articulacy." It refers to the skill of expressing ideas clearly and effectively in a way that is easily understood by others. Articulacy is essential for effective communication, especially when discussing intricate or abstract concepts. **
