It is also used in digital image processing and compression to represent the background or empty pixels. Technology: Zero is used in computer programming as a null value to indicate the absence of data.In electrical engineering, zero volts are used as a reference voltage level. Science: In physics, zero is used as a reference point for measuring temperature, pressure, and other physical quantities.Mathematics: Zero is used as a placeholder in our numbering system, and it also forms the basis of the number line, allowing us to understand and compare positive and negative numbers. Zero has a wide range of applications in various fields, including mathematics, science, technology, and finance. The Hindu-Arabic numeral system, which includes zero, quickly spread throughout the Islamic world and eventually made its way to Europe through trade and cultural exchange. The modern representation of zero as a digit was introduced by the Arabic-speaking mathematician Al-Khwarizmi in the 9th century, who also popularized the use of the Hindu-Arabic numeral system. The Indian mathematician and astronomer Aryabhata also made important contributions to the understanding of zero as both a placeholder and a number in its own right. The Indian mathematician Brahmagupta was one of the first to give mathematical rules for the operations involving zero, such as the result of dividing by zero. The Babylonians used a symbol for zero as a placeholder in their numbering system, while the Mayans developed a sophisticated numerical system that included the concept of zero. Figure 1: Symbol and operations on zero BackgroundĪround 3,000 years ago, the ancient Babylonians and Mayans created the idea of zero as a number.
