Stephen William Hawking (born 8 January 1942) is an English theoretical physicist, cosmologist, author and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. Among his significant scientific works have been a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity, and the theoretical prediction that black holes emit radiation, often called
Hawking radiation. Hawking was the first to set forth a cosmology explained by a union of the general theory of relativity and quantum mechanics.
He is a vigorous supporter of the many-worlds interpretation of quantum mechanics.His book his A Brief History of Time stayed on the British Sunday Times best-sellers list for a record-breaking 237 weeks. Hawking suffers from a rare, early-onset, slow-progressing form of amyotrophic lateral sclerosis (ALS), or motor neurone disease, that has gradually paralyzed him over the decades.
In his work, and in collaboration with Penrose, Hawking extended the singularity theorem concepts first explored in his doctoral thesis. This included not only the existence of singularities but also the theory that the Universe might have started as a singularity.
Nectar guides are markings or patterns seen in flowers of some angiosperm species, that guide pollinators to their rewards. Rewards commonly take the form of nectar, pollen, or both. These patterns are sometimes visible to humans; for instance, the Dalmatian toadflax (Linaria genistifolia) has yellow flowers with orange nectar guides. However, in some plants, such as sunflowers, they are visible only when viewed in ultraviolet light.
Under ultraviolet, the flowers have a darker center, where the nectaries are located, and often specific patterns upon the petals as well. This is believed to make the flowers more attractive to pollinators such as honey bees and other insects that can see ultraviolet. The ultraviolet color, invisible to humans, has been referred to as bee violet, and mixtures of greenish (yellow) wavelengths (roughly 540 nm) with ultraviolet are called bee purple by analogy with purple in human vision.

Rabindranath Tagore (7 May 1861 – 7 August 1941), Gurudev, reshaped Bengali literature and music, as well as Indian art with Contextual Modernism in the late 19th and early 20th centuries. Author of Gitanjali and its “profoundly sensitive, fresh and beautiful verse”, he became the first non-European to win the Nobel Prize in Literature in 1913.In translation his poetry was viewed as spiritual and mercurial; Tagore introduced new prose and verse forms and the use of colloquial language into Bengali literature, thereby freeing it from traditional models based on classical Sanskrit. His novels, stories,songs, dance-dramas, and essays spoke to topics political and personal. Gitanjali (Song Offerings), Gora (Fair-Faced) and Ghare-Baire (The Home and the World) are his best-known works, and his verse, short stories, and novels were acclaimed—or panned—for their lyricism, colloquialism, naturalism, and unnatural contemplation.

Frank Lloyd Wright (born Frank Lincoln Wright, June 8, 1867 – April 9, 1959) was an American architect, interior designer, writer, and educator, who designed more than 1,000 structures and completed 532. Wright believed in designing structures that were in harmony with humanity and its environment, a philosophy he called organic architecture. This philosophy was best exemplified by Fallingwater (1935), which has been called “the best all-time work of American architecture”. Wright was recognized in 1991 by the American Institute of Architects as “the greatest American architect of all time”.
Werner Karl Heisenberg (5 December 1901 – 1 February 1976) was a German theoretical physicist and one of the key pioneers of quantum mechanics. In 1927 he published his uncertainty principle, upon which he built his philosophy and for which he is best known. Heisenberg was awarded the Nobel Prize in Physics for 1932 “for the creation of quantum mechanics. In 1928, Albert Einstein had nominated Heisenberg, Born, and Jordan for the Nobel Prize in Physics, but it was not to be. The announcement of the Nobel Prize in Physics for 1932 was delayed until November 1933.It was at that time that it was announced Heisenberg had won the Prize for 1932 “for the creation of quantum mechanics.
In 1954, Heisenberg wrote an article honoring Max Planck for his insight in 1900. In the article, Heisenberg credited Born and Jordan for the final mathematical formulation of matrix mechanics and Heisenberg went on to stress how great their contributions were to quantum mechanics, which were not “adequately acknowledged in the public eye.”
“What we observe is not nature itself, but nature exposed to our method of questioning.”-Werner Heisenberg
Richard Phillips Feynman was an American theoretical physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics (he proposed the parton model). For his contributions to the development of quantum electrodynamics, Feynman, jointly with Julian Schwinger and Sin-Itiro Tomonaga, received the Nobel Prize in Physics in 1965.
He developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime, Feynman became one of the best-known scientists in the world. In a 1999 poll of 130 leading physicists worldwide by the British journal Physics World he was ranked as one of the ten greatest physicists of all time.
Jiddu Krishnamurti (12 May 1895 – 17 February 1986) was an Indian speaker and writer on philosophical and spiritual subjects. In his early life he was groomed to be the new World Teacher but later rejected this mantle and disbanded the organisation behind it. His subject matter included psychological revolution, the nature of
mind, meditation, inquiry, human relationships, and bringing about radical change in society. He constantly stressed the need for a revolution in the psyche of every human being and emphasised that such revolution cannot be brought about by any external entity.
He claimed allegiance to no nationality, caste, religion, or philosophy, and spent the rest of his life traveling the world, speaking to large and small groups and individuals. He wrote many books, among them The First and Last Freedom, The Only Revolution, and Krishnamurti’s Notebook. Many of his talks and discussions have been published. His last public talk was in Madras, India, in January 1986, a month before his death at his home in Ojai, California.

Chrysanthemums, sometimes called mums or chrysanths, are flowering plants of the genus Chrysanthemum. They are native to Asia and northeastern Europe. The name “chrysanthemum” is derived from the Greek words chrysos (gold) and anthemon (flower). The “Festival of Happiness” in Japan celebrates the flower. Over 140 varieties of chrysanthemum have gained the Royal Horticultural Society’s Award of Garden Merit. Chrysanthemums are perennial plants. A perennial plant or simply perennial is a plant that lives for more than two years. Yellow or white chrysanthemum flowers of the species C. morifolium are boiled to make a sweet drink in some parts of Asia.
Max Planck, was a German theoretical physicist who originated quantum theory, which won him the Nobel Prize in Physics in 1918. Planck made many contributions to theoretical physics, but his fame as a physicist rests primarily on his role as an originator of the quantum theory. Max Planck’s quantum theory revolutionized human understanding of atomic and subatomic processes, just as Albert Einstein’s theory of relativity revolutionized the understanding of space and time. Together they constitute the fundamental theories of 20th-century physics. Planck was gifted when it came to music. He took singing lessons and played piano, organ and cello, and composed songs and operas. However, instead of music he chose to study physics.
Cosmos are herbaceous perennial plants growing 0.3–2 m (1 ft 0 in–6 ft 7 in) tall. Interesting Fact: Herbaceous perennial and biennial plants have stems that die at the end of the growing season, but parts of the plant survive under or close to the ground from season to season (for biennials, until the next growing season, when they flower and die). New growth develops from living tissues remaining on or under the ground, including roots, a caudex (a thickened portion of the stem at ground level) or various types of underground stems, such as bulbs, corms, stolons, rhizomes and tubers.
