One notable example is the 90 mm gun used by some militaries during the mid-20th century, such as the United States and several other NATO and non-NATO countries.

The 94th meridian west is a line of longitude that is 94 degrees west of the Prime Meridian, which is the line of longitude at 0 degrees. This meridian runs from the North Pole to the South Pole and passes through several U.S. states, including parts of Minnesota, Wisconsin, Iowa, Missouri, Kansas, Oklahoma, and Texas. It also passes through various geographical features and regions, influencing local time zones and climate patterns.

In the 9th century, notable mathematicians emerged from various cultural and geographical backgrounds, particularly within the Islamic world and Europe. Here's a brief overview by nationality or region: ### Islamic World 1. **Al-Khwarizmi** (Persian) - Often hailed as the "father of algebra," Al-Khwarizmi's works were foundational in developing algebra and introducing the decimal positional number system to the West.

The 9th meridian west is a line of longitude that is located 9 degrees west of the Prime Meridian, which is at 0 degrees longitude. This meridian runs from the North Pole to the South Pole and passes through several countries in Europe and Africa. In Europe, the 9th meridian west primarily passes through parts of the United Kingdom and Ireland, with the western edge of England and the eastern edge of Ireland being significant locations.

A¹ homotopy theory is a branch of algebraic topology that is concerned with the study of homotopy theories in the context of algebraic varieties over a field, particularly a field with a non-Archimedean valuation or more generally over a base scheme. It is primarily developed in the framework of stable and unstable homotopy types, where the concepts of homotopy can be adapted to the settings of algebraic geometry.

The A. A. Griffith Medal and Prize is an award given by the Institute of Materials, Minerals and Mining (IOM3) in the UK. It is named after the eminent scientist A. A. Griffith, who made significant contributions to the fields of materials science and engineering, particularly in the areas of fracture mechanics and the study of materials' properties.

The AAI Aerosonde is a type of small unmanned aerial vehicle (UAV) designed primarily for atmospheric research and surveillance purposes.
