History of the Anemometer Wind Vane

History of the Anemometer Wind Vane Wind velocity or speed is measured by a cup anemometer, an instrument with three or four small hollow metal hemispheres set so that they catch the wind and revolve about a vertical rod. An electrical device records the revolutions of the cups and calculates the wind velocity. The word anemometer comes from the Greek word for wind, anemos. Mechanical Anemometer In 1450, the Italian art architect Leon Battista Alberti invented the first mechanical anemometer. This instrument consisted of a disk placed perpendicular to the wind. It would rotate by the force of the wind, and by the angle of inclination of the disk the wind force momentary showed itself. The same type of anemometer was later re-invented by Englishman Robert Hooke who is often mistakenly considered the inventor of the first anemometer. The Mayans were also building wind towers (anemometers) at the same time as Hooke. Another reference credits Wolfius as re-inventing the anemometer in 1709. Hemispherical Cup Anemometer The hemispherical cup anemometer (still used today) was invented in 1846 by Irish researcher, John Thomas Romney Robinson and consisted of four hemispherical cups. The cups rotated horizontally with the wind and a combination of wheels recorded the number of revolutions in a given time. Want to build your own hemispherical cup anemometer Sonic Anemometer A sonic anemometer determines instantaneous wind speed and direction (turbulence) by measuring how ​much sound waves traveling between a pair of transducers are sped up or slowed down by the effect of the wind. The sonic anemometer was invented by geologist Dr. Andreas Pflitsch in 1994.

DAP also recognizes the individual child as much as the diversity of the socio-economic and cultural environments that contribute to the differences in children's perceptions that they carry with them while attending early education. There are certain elements that make developmentally appropriate programs well suited to the aim of supporting the development of children in their education. These are knowledge or information used to come up with learning programs, the learning environment which is the dynamic interface between children and the educators, whether inside or outside the school system, and the policies which serve to institutionalize the mechanisms that make DAP continuously responsive to its aims. Knowledge as a key element of DAP allows educators to come up with learning programs and applications that are guideposts on what will work or not for the development of children. ... Furthermore, knowledge of varying socio-economic and cultural contexts as applied in DAP allows for relevance among children and families coming from different backgrounds. The learning environment as an element of DAP encompasses the interface between young children and the all the actors such as teachers, families and other children. It also includes the inter-related practices of teaching, developing curricula and the feedback processes that go with DAP. The learning environment is where social interactions and relationship skills are developed, that is why DAP is committed to fostering a safe and caring environment for young children. Continuous assessment of how children fare in learning programs also constitutes an important facet of the learning environment. Policies also constitute an important element of DAP in as much as they make learning programs committed to the development of young children viable. These include formal mechanisms that would set up personnel with the needed expertise, funding and other guidelines that serve as rules when certain expectations under DAP are not met. 2. What are the underlying values of DEC Recommended Practices According to the Division for Early Childhood of the Council (no date) for Exceptional Children or DEC, Recommended Practices are important because RP "represents collective wisdom, identifies what practices work, provides a framework to define quality, supports positive outcomes and applies to all settings". Instead on focusing on the larger framework of locating the child in the greater milieu of the education system or the society and to a certain extent and taking off from there, the approach is more evidence-based and is more geared towards what is practical and works.
