Spinning wheel

A spinning wheel is a device for spinning thread or yarn from natural or synthetic fibres. Spinning wheels appeared in China, probably in the 11th century, and very gradually replaced hand spinning with spindle and distaff. Spinning machinery, such as the spinning jenny and spinning frame, displaced the spinning wheel during the Industrial Revolution.

History

The earliest clear illustrations of the spinning wheel come from Baghdad (drawn in 1234), China (c. 1270) and Europe (c. 1280), and there is evidence that spinning wheels had already come into use in both China and the Islamic world during the eleventh century. According to Irfan Habib, the spinning wheel was introduced into India from Iran in the thirteenth century. In France the spindle and distaff were not displaced until the mid 18th century.

The spinning wheel replaced the earlier method of hand spinning with a spindle. The first stage in mechanizing the process was mounting the spindle horizontally so it could be rotated by a cord encircling a large, hand-driven wheel. The great wheel is an example of this type, where the fibre is held in the left hand and the wheel slowly turned with the right. Holding the fibre at a slight angle to the spindle produced the necessary twist. The spun yarn was then wound onto the spindle by moving it so as to form a right angle with the spindle. This type of wheel, while known in Europe by the 14th century, was not in general use until later. The construction of the Great Wheel made it very good at creating long drawn soft fuzzy wools, but very difficult to create the strong smooth yarns needed to create warp for weaving. Spinning wheels ultimately did not develop the capability to spin a variety of yarns until the beginning of the 19th century and the mechanization of spinning.

Wheel

A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the main components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel and flywheel.

Common examples are found in transport applications. A wheel greatly reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, either by way of gravity, or by the application of another external force or torque.

Etymology

The English word wheel comes from the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *k^wek^wlo-, an extended form of the root *k^wel- "to revolve, move around". Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, the latter both meaning "circle" or "wheel".

Toy

A toy is an item that can be used for play. Toys are generally played with by children and pets. Playing with toys is an enjoyable means of training young children for life in society. Different materials are used to make toys enjoyable to all ages. Many items are designed to serve as toys, but goods produced for other purposes can also be used. For instance, a small child may pick up a household item and "fly" it through the air as to pretend that it is an airplane. Another consideration is interactive digital entertainment. Some toys are produced primarily as collector's items and are intended for display only.

The origin of toys is prehistoric; dolls representing infants, animals, and soldiers, as well as representations of tools used by adults are readily found at archaeological sites. The origin of the word "toy" is unknown, but it is believed that it was first used in the 14th century. Toys are mainly made for children.

Playing with toys is important when it comes to growing up and learning about the world around us. Younger children use toys to discover their identity, help their bodies grow strong, learn cause and effect, explore relationships, and practice skills they will need as adults. Adults use toys to form and strengthen social bonds, teach, remember and reinforce lessons from their youth, discover their identity, exercise their minds and bodies, explore relationships, practice skills, and decorate their living spaces.

Blood, Sweat & Tears

Blood, Sweat & Tears (also known as "BS&T") is a contemporary jazz-rock American music group. They are noted for their combination of brass and rock band instrumentation. The group recorded songs by rock/folk songwriters such as Laura Nyro, James Taylor, the Band, the Rolling Stones, as well as Billie Holiday and Erik Satie. They also incorporated music from Thelonious Monk and Sergei Prokofiev into their arrangements.

They were originally formed in 1967 in New York City. Since their beginnings, the band has gone through numerous iterations with varying personnel and has encompassed a multitude of musical styles. The band is most notable for fusing of rock, blues, pop music, horn arrangements and jazz improvisation into a hybrid that came to be known as "jazz-rock". Unlike "jazz fusion" bands, which tend toward virtuosic displays of instrumental facility and some experimentation with electric instruments, the songs of Blood, Sweat & Tears merged the stylings of rock, pop and R&B/soul music with big band, while also adding elements of 20th Century Classical and small combo jazz traditions.
