Nature








Earth is estimated to have formed 4.55 billion years ago from the solar nebula, along with the Sun and other planets. The moon formed roughly 20 million years later. Initially molten, the outer layer of the planet cooled, resulting in the solid crust. Outgassing and volcanic activity produced the primordial atmosphere. Condensing water vapor, most or all of which came from ice delivered by comets, produced the oceans and other water sourcesThe highly energetic chemistry is believed to have produced a self-replicating molecule around 4 billion years ago.

Beauty in nature has long been a common theme in life and in art, and books emphasizing beauty in nature fill large sections of libraries and bookstores. That nature has been depicted and celebrated by so much art, photography, poetry and other literature shows the strength with which many people associate nature and beauty. Why this association exists, and what the association consists of, is studied by the branch of philosophy called aesthetics. Beyond certain basic characteristics that many philosophers agree about to explain what is seen as beautiful, the opinions are virtually endless.
Looked at through the lens of the
visual arts nature and wildness have been important subjects in various epochs of world history. An early tradition of landscape art began in China during the Tang Dynasty (618-907). The tradition of representing nature as it is became one of the aims of Chinese painting and was a significant influence in Asian art. Artists learned to depict mountains and rivers "from the perspective of nature as a whole and on the basis of their understanding of the laws of nature ... as if seen through the eyes of a bird." In the 13th century, the Song Dynasty artist Shi Erji listed "scenes lacking any places made inaccessible by nature," as one of the 12 things to avoid in painting.
In the Western world the idea of wilderness having intrinsic value emerged in the 1800s, especially in the works of the Romantic movement. British artists John Constable and JMW Turner turned their attention to capturing the beauty of the natural world in their paintings. Before that, paintings had been primarily of religious scenes or of human beings. William Wordsworth’s poetry described the wonder of the natural world, which had formerly been viewed as a threatening place.
Many scientists, who study nature in more specific and organized ways, also share the conviction that nature is beautiful






FLOWERS
Flowers are the beauyt of nature
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to mediate the union of male sperm with female ovum in order to produce seeds. The process begins with pollination, is followed by fertilization, leading to the formation and dispersal of the seeds. For the higher plants, seeds are the next generation, and serve as the primary means by which individuals of a species are dispersed across the landscape. The grouping of flowers on a plant is called the inflorescence.
In addition to serving as the reproductive organs of floweri
ng plants, flowers have long been admired and used by humans, mainly to beautify their environment but also as a source of food.

Many flowers have important symbolic meanings in Western culture. The practice of assigning meanings to flowers is known as floriography. Some of the more common examples include:

Red roses are given as a symbol of love, beauty, and passion.
Poppies are a symbol of consolation in time of death. In the UK, New Zealand, Australia and Canada, red poppies are worn to commemorate soldiers who have died in times of war.
Irises/Lily are used in burials as a symbol referring to "resurrection/life". It is also associated with stars (sun) and its petals blooming/shining.
Daisies are a symbol of innocence


ROSES


A rose is a perennial flower shrub or vine of the genus Rosa, within the family Rosaceae, that contains over 100 species and comes in a variety of colours. The species form a group of erect shrubs, and climbing or trailing plants, with stems that are often armed with sharp prickles. It is a common error to refer to roses having thorns. Thorns are modified branches or stems, whereas these sharp protrusions on a rose are modified epidermal tissues (prickles). Most are native to Asia, with smaller numbers of species native to Europe, North America, and northwest Africa. Natives, cultivars and hybrids are all widely grown for their beauty and fragrance.

The rose has always been valued for its beauty and has a long history of symbolism. The ancient Greeks and Romans identified the rose with their goddesses of love referred to as Aphrodite and Venus. In Rome a wild rose would be placed on the door of a room where secret or confidential matters were discussed. The phrase sub rosa, or "under the rose", means to keep a secret — derived from this ancient Roman practice.
Early Christians identified the five petals of the rose with the five wounds of Christ. Despite this interpretation, their leaders were hesitant to adopt it because of its association with Roman excesses and pagan ritual. The red rose was eventually adopted as a symbol of the blood of the Christian martyrs. Roses also later came to be associated with the Virgin Mary.
Rose culture came into its own in Europe in the 1800s with the introduction of perpetual blooming roses from China. There are currently thousands of varieties of roses developed for bloom shape, size, fragrance and even for lack of prickles.

Art

Roses are often portrayed by artists. The Luxembourg born Belgian artist Pierre-Joseph Redouté produced some of the most detailed paintings of roses.
Henri Fantin-Latour was also a prolific painter of still life, particularly flowers including roses. The Rose 'Fantin-Latour' was named after the artist.
Other impressionists including Claude Monet, Paul CĂ©zanne and Pierre-Auguste Renoir have paintings of roses among their works.
