Association of british science writers awards and plaques

Events are hosted here for the public, RSC member groups and external organisations including monthly lectures on the chemical sciences that streamed live via the RSC's public engagement website — the Reaction. The free lectures take an interesting look at the chemical aspects of a wide range of topics from curry to the enjoyment of music. The events have attracted notable science writers such as Philip BallAntony John Williamsand John Emsley to give public lectures. Most of these are available as archived video streams via the RSC's Reaction website.

Idiophones Idiophones form a diverse and disparate group. Concussion instruments, consisting of two similar components struck together, include clappers, concussion stones, castanetsand cymbals. Percussion idiophones, instruments struck by a nonsonorous striker, form a large subgroup, including triangles and simple percussion sticks; percussion beams, such as the semanterion ; percussion disks and plaques, single and in sets; xylophoneslithophones sonorous stonesand metallophones sets of tuned metal bars ; percussion tubes, such as stamping tubes, slit drums, and tubular chimes; and percussion vessels varying from struck gourds and pots to gongskettle gongs, steel drumsbellsand musical cups.

Bronze Egyptian sistrum, dated after bc crossbars and jingles are modern ; in the British Museum, London. Membranophones Musical instruments in which the sound-producing medium is a vibrating membrane fall into four main groups: Strictly speaking, mirlitons are voice modifiers rather than true musical instruments inasmuch as they have no pitch of their own.

Kettledrums and tubular drums occur in both tunable and nontunable forms; friction drums and mirlitons are not tunable. The membranes of the first two groups are either glued, nailed, lapped, or laced to the body, or shell; if they are glued or nailed, the pitch can be modified by exposure to heat.

The membranes of such instruments and of friction drums are set in vibration by percussion, while those of mirlitons vibrate by impact of sound waves. In all groups the shell plays a subordinate acoustical part, acting as resonator only—the greater the diameter of a head, the deeper its sound; and the greater its tension, the higher the pitch.

In Western culture the only drums tuned to a definite pitch are kettledrums the orchestral timpani.

Flemish rommelpot friction drum; in the Musical Instruments Museum, Brussels. Beaters can be cylindrical, club-shaped, straight, curved, or angled, with or without knobs or padding, or may take the form of a switch or wire brush.

Acousticallythey are subject to the same laws as other membranophones, but the speed of friction is an influencing factor. In addition to the four major categories of membranophones, a small group composed of ground drums and pot drums can also be distinguished.

Ground drums, consisting in their simplest form of an animal skin stretched over the opening of a pit, are found in many parts of the world. The skin may also be held taut by several players, each beating it with a stick. These and similar ground drums are played by women in Africa and Australia, and in North America usually by men.

By their very nature ground drums are nonportable; a similar type of instrument was made by stretching a skin over the opening of a gourd, clay pot, or other object.

Among the Swazi of southern Africa such skins are not attached but held taut.

Pot drums are found in Asia, Africa, and the Americas—in Africa and the Americas often in connection with exorcism. Percussion instruments in Europe Antiquity Europe received most of its percussion instruments either directly or indirectly from the sophisticated cultures of the ancient Middle East or from Egypt, a country regarded by the Greeks and Romans as forming part of Asia rather than Africa a practice that will be followed in this article for convenience.

Idiophones European antiquity knew many idiophones. The time-beating foot clappers of chorus leaders, attached to the right foot like a sandal, were known in Greece as kroupezai, or kroupala, and were adopted by Rome as the scabella.

When the Egyptian cult of Isis spread to Greece and Rome, her sistrum followed, always in the hands of a priest or—rarely—priestess.The Independent’s science editor Steve Connor won the best investigation prize at last night’s Association of British Science Writers awards.

The first was finding famous and influential people to inscribe plaques and awards of endorsement for the organizers to enhance their credibility. The second was money. Every one of the masters he once admired and respected was using deception and trickery in order to manipulate people.

Extensive documentation of the National Newspaper Publishers Association, the Chicago Defender, the Pittsburgh Courier, the Michigan Chronicle, Provident Hospital and the political history of Chicago is included.

The papers feature correspondence, manuscripts, organizational and subject research files, biographical materials, programs.
