Josiah Holbrook
Josiah Holbrook (June 17, 1788 – June 20, 1854) was the initiator and organizer of the lyceum movement in the United States. He formed the first industrial school in the country in 1819, organized the first lyceum school in the country in 1826 and inspired the foundation of the American Lyceum Association, the first national education association. He founded the Holbrook School Apparatus Manufacturing Company and made a variety of teacher aid items for common schools and scientific training aids for teachers to use in lyceums. He also wrote and traveled extensively to promote the lyceum concept. His method combined teaching in academic subjects like Greek, history and mathematics with practical farming skills and crafts. In the beginning, his system flourished in the New England states, later branching out into the Midwestern states, and eventually going nationwide to 3,000 towns and cities. He was also an advocate of professional teacher training and broadening female educatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agronomy
Agronomy is the science and technology of producing and using plants by agriculture for food, fuel, fiber, chemicals, recreation, or land conservation. Agronomy has come to include research of plant genetics, plant physiology, meteorology, and soil science. It is the application of a combination of sciences such as biology, chemistry, economics, ecology, earth science, and genetics. Professionals of agronomy are termed agronomists. Plant breeding This topic of agronomy involves selective breeding of plants to produce the best crops for various conditions. Plant breeding has increased crop yields and has improved the nutritional value of numerous crops, including corn, soybeans, and wheat. It has also resulted in the development of new types of plants. For example, a hybrid grain named triticale was produced by crossbreeding rye and wheat. Triticale contains more usable protein than does either rye or wheat. Agronomy has also been instrumental for fruit and vegetable producti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orrery
An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model. It may also represent the relative sizes of these bodies; however, since accurate scaling is often not practical due to the actual large ratio differences, a subdued approximation may be used instead. Though the Greeks had working planetaria, the first orrery that was a planetarium of the modern era was produced in 1704, and one was presented to Charles Boyle, 4th Earl of Orrery – hence the name. They are typically driven by a clockwork mechanism with a globe representing the Sun at the centre, and with a planet at the end of each of the arms. History Ancient versions The Antikythera mechanism, discovered in 1901 in a wreck off the Greek island of Antikythera in the Mediterranean Sea, (it now resides in the National Archaeological Museum of Athens) and extensively studied, exhibited the diu ...

Cube Root
In mathematics, a cube root of a number is a number such that . All nonzero real numbers, have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of , denoted \sqrt[3]8, is , because , while the other cube roots of are -1+i\sqrt 3 and -1-i\sqrt 3. The three cube roots of are :3i, \quad \frac-\fraci, \quad \text \quad -\frac-\fraci. In some contexts, particularly when the number whose cube root is to be taken is a real number, one of the cube roots (in this particular case the real one) is referred to as the ''principal cube root'', denoted with the radical sign \sqrt[3]. The cube root is the inverse function of the cube (algebra), cube function if considering only real numbers, but not if considering also complex numbers: although one has always \left(\sqrt[3]x\right)^3 =x, the cube of a nonzero number has more than one complex cube root and its ...

Millbury, Massachusetts
Millbury, officially the Town of Millbury, is a town in Worcester County, Massachusetts. Located within Blackstone Valley, the population in Millbury was 13,831 at the 2020 United States Census. History Millbury was first settled by Europeans in 1716. It was originally known as the Second or North Parish of Sutton. Because traveling from one part of the town to the other for meetings was time-consuming, inhabitants of the North Parish petitioned the Massachusetts General Court to split Sutton. North Parish became Millbury on June 11, 1813 by way of an act of incorporation. Its name derived from its long history as a mill town. The Blackstone River flows through the town, and during the Industrial Revolution, provided water power to its many textile mills and factories. During this time, the inventor William Crompton worked in Millbury. Millbury's industrial history begins in the early eighteenth century, not long after the area's settlement. In 1735, John Singletary began op ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
