who is credited with proposing the principle of uniformitarianism
Uniformitarianism In geology, uniformitarianism has included the gradualistic concept that "the present is the key to the past" (that events occur at the same rate now as they have always done); many geologists now, however, no longer hold to a strict theory of gradualism.[6] Coined by William Whewell, the word was proposed in contrast to catastrophism[7] by British naturalists in the late 18th century, starting with the work of the geologist James Hutton in his many books including Theory of the Earth[8]. Hutton's work was later refined by scientist John Playfair and popularised by geologist Charles Lyell's Principles of Geology in 1830.[9] Today, Earth's history is considered to have been a slow, gradual process, punctuated by occasional natural catastrophic events.
School uniform It is difficult to trace the origins of the uniform as there is no comprehensive written history, but rather a variety of known influences. School uniforms are believed to be a practice which dates to the 16th century in the United Kingdom. It is believed that the Christ Hospital School in London in 1552 was the first school to use a school uniform.[3] The earliest documented proof of institutionalised use of a standard academic dress dates back to 1222 when the then Archbishop of Canterbury ordered the wearing of the cappa clausa.[4] This monastic and academic practice evolved into collegiate uniforms in England, particularly in charity schools where uniform dress was often provided for poor children. Universities, primary schools and secondary schools used uniforms as a marker of class and status.[5] Although school uniforms can often be considered conservative and old-fashioned, uniforms in recent years have changed as societal dress codes have changed.[6]
