  • Imperial Units
    Imperial units From Wikipedia, the free encyclopedia Jump to: navigation, search This article is about the post-1824 measures used in the British Empire and countries in the British sphere of influence. For the units used in England before 1824, see English units. For the system of weight, see Avoirdupois. For United States customary units, see Customary units . Imperial units or the imperial system is a system of units, first defined in the British Weights and Measures Act of 1824, later refined (until 1959) and reduced. The system came into official use across the British Empire. By the late 20th century most nations of the former empire had officially adopted the metric system as their main system of measurement. The former Weights and Measures office in Seven Sisters, London.

Although most of the units are defined in more than one system, some subsidiary units were used to a much greater extent, or for different purposes, in one area rather than the other. The distinctions between these systems are often not drawn precisely.

  • History of Texas Public Lands
    Understanding the importance of land in the history of Texas is essential to understanding Texas. Few Texans, however, are aware of the role that public land has played in our state's development. Land has not only furnished us valuable natural resources, it has been used to finance government operations, reward veterans, provide internal improvements and fund public education. The land myth in Texas is real. The information included here traces the disposition, use and settlement of public land in Texas. Initially conceived to supplement and enhance the story of public lands outlined in Texas school textbooks, the content has been modified to appeal to a broad audience while retaining its original instructional intent. A glossary and bibliography of suggested readings are also included at the bottom of this document. Teachers may find the appendix, "Empresarios, Commissioners and Settlers: The Process of Land Distribution in Mexican Texas," particularly suited to their needs. The Spanish Period Spain claimed the land that is now Texas in 1519, when the explorer Alonzo Alvarez de Piñeda sailed along the Gulf Coast to the Rio Grande. Later, in hopes of finding mineral riches, other Spanish explorers came to Texas. But because they didn't find the quick wealth they sought, Spain ignored Texas until 1685, when France's René Robert Cavelier, Sieur de la Salle, established a fort at Matagorda Bay and claimed the area for France. To protect its claim, Spain needed to establish a presence in Texas, but with plenty of land at home Spanish subjects in Mexico were unwilling to move to this faraway, dangerous land.

These measurements may seem a bit odd to those folks who are used to feet, pounds, and miles per hour, but the truth is that scientists sneer at feet, pounds, and miles. Because scientists around the globe constantly communi- cate numbers to each other, they prefer a highly systematic, standardized system. The International System of units, abbreviated SI from the French term Système International, is the unit system of choice in the scientific community. You find in this chapter that the SI system is a very logical and well organized set of units. Despite what many of their hairstyles may imply, scientists love logic and order, so that’s why SI is their system of choice. As you work with SI units, try to develop a good sense for how big or small the various units are. Why? That way, as you’re doing problems, you have a sense for whether your answer is reasonable. Familiarizing Yourself with Base Units and Metric System Prefixes The first step in mastering the SI system is to figure out the base units. Much like the atom, the SI base units are building blocks for more complicated units. In later sections of this chapter, you find out how more complicated units are built from the SI base units.

  • The Units of Length in the Spanish Treatises of Military Engineering
    The Global and the Local: The History of Science and the Cultural Integration of Europe. nd Proceedings of the 2 ICESHS (Cracow, Poland, September 6–9, 2006) / Ed. by M. Kokowski. Juan Navarro Loidi *, Pilar Merino Saenz ** The units of length in the Spanish treatises of military engineering (1) Introduction In this article we study the units of length used by the Spanish military engineers from the Renaissance up to the second half of the 19th century. To do that, we have considered principally the treatises published for the formation of these professionals. Many different units of length had been used since the military engineering arose as a new profession in Spain until the full acceptance of the Metric Decimal System in the country. This variety of units was due, first, to the existence of several different kingdoms with their own units in what is nowadays Spain. Also to the fact that the Spanish troops fought in many European countries during the 16th and 17th centuries. Finally, to the lack of a national tradition in fortification. At the same time, in Spain, as in other many countries, there was a trend to have a natural coherent system of measurements, reproducible and of easy use. The Crown wanted also the unification of the units of measurement of the kingdom, as in any other country. To help the comprehension of what is exposed in this communication, it is convenient to begin summarizing the history of the units of measurements in Spain up to the introduction of the Metric Decimal System and the history of the Spanish military engineering.
