INTERNATIONAL YOGA DAY

 

Yoga is an ancient physical, mental and spiritual practice that originated in India. The word ‘yoga’ derives from Sanskrit and means to join or to unite, symbolizing the union of body and consciousness.

Today it is practiced in various forms around the world and continues to grow in popularity.

Recognizing its universal appeal, on 11 December 2014, the United Nations proclaimed 21 June as the International Day of Yoga by resolution 69/131.

The International Day of Yoga aims to raise awareness worldwide of the many benefits of practicing yoga.

The draft resolution establishing the International Day of Yoga was proposed by India and endorsed by a record 175 member states. The proposal was first introduced by Prime Minister Narendra Modi in his address during the opening of the 69th session of the General Assembly, in which he said: “Yoga is an invaluable gift from our ancient tradition. Yoga embodies unity of mind and body, thought and action ... a holistic approach [that] is valuable to our health and our well-being. Yoga is not just about exercise; it is a way to discover the sense of oneness with yourself, the world and the nature.”

Nicolaus Copernicus

 

Nicolaus Copernicus (/koʊˈpɜːrnɪkəs, kə-/;^[2][3][4] Polish: Mikołaj Kopernik;^[b] Middle Low German: Niklas Koppernigk, German: Nikolaus Kopernikus; 19 February 1473 – 24 May 1543) was a Renaissance polymath, active as a mathematician, astronomer, and Catholic canon, who formulated a model of the universe that placed the Sun rather than Earth at its center. In all likelihood, Copernicus developed his model independently of Aristarchus of Samos, an ancient Greek astronomer who had formulated such a model some eighteen centuries earlier.^[5][c][d][e]

The publication of Copernicus's model in his book De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), just before his death in 1543, was a major event in the history of science, triggering the Copernican Revolution and making a pioneering contribution to the Scientific Revolution.^[7]

Copernicus was born and died in Royal Prussia, a region that had been part of the Kingdom of Poland since 1466. A polyglot and polymath, he obtained a doctorate in canon law and was a mathematician, astronomer, physician, classics scholar, translator, governor, diplomat, and economist. From 1497 he was a Warmian Cathedral chapter canon. In 1517 he derived a quantity theory of money—a key concept in economics—and in 1519 he formulated an economic principle that later came to be called Gresham's law.^[f]

Paul Dirac

 

Paul Adrien Maurice Dirac OM FRS^[9] (/dɪˈræk/; 8 August 1902 – 20 October 1984) was an English theoretical physicist who is considered to be one of the founders of quantum mechanics and quantum electrodynamics.^[10] He was the Lucasian Professor of Mathematics at the University of Cambridge, a professor of physics at Florida State University and the University of Miami, and a 1933 Nobel Prize in Physics recipient.

Dirac made fundamental contributions to the early development of both quantum mechanics and quantum electrodynamics. Among other discoveries, he formulated the Dirac equation which describes the behaviour of fermions and predicted the existence of antimatter. Dirac shared the 1933 Nobel Prize in Physics with Erwin Schrödinger "for the discovery of new productive forms of atomic theory".^[11] He also made significant contributions to the reconciliation of general relativity with quantum mechanics.

Dirac was regarded by his friends and colleagues as unusual in character. In a 1926 letter to Paul Ehrenfest, Albert Einstein wrote of a Dirac paper, "I am toiling over Dirac. This balancing on the dizzying path between genius and madness is awful." In another letter concerning the Compton effect he wrote, "I don't understand the details of Dirac at all."^[12]

Galileo Galilei

 Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642) was an Italian astronomer, physicist and engineer, sometimes described as a polymath. Commonly referred to as Galileo, his name is pronounced /ˌɡælɪˈleɪ.oʊ ˌɡælɪˈleɪ.iˌ/ (GAL-ih-LAY-oh GAL-ih-LAY-ee, Italian: [ɡaliˈlɛːo ɡaliˈlɛi]). He was born in the city of Pisa, then part of the Duchy of Florence.^[4] Galileo has been called the father of observational astronomy,^[5] modern-era classical physics,^[6] the scientific method,^[7] and modern science.^[8]

Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and "hydrostatic balances". He invented the thermoscope and various military compasses, and used the telescope for scientific observations of celestial objects. His contributions to observational astronomy include telescopic confirmation of the phases of Venus, observation of the four largest satellites of Jupiter, observation of Saturn's rings, and analysis of lunar craters and sunspots.

Galileo's championing of Copernican heliocentrism (Earth rotating daily and revolving around the Sun) was met with opposition from within the Catholic Church and from some astronomers. The matter was investigated by the Roman Inquisition in 1615, which concluded that heliocentrism was foolish, absurd, and heretical since it contradicted Holy Scripture.^[9][10][11]

Galileo later defended his views in Dialogue Concerning the Two Chief World Systems (1632), which appeared to attack Pope Urban VIII and thus alienated both the Pope and the Jesuits, who had both supported Galileo up until this point.^[9] He was tried by the Inquisition, found "vehemently suspect of heresy", and forced to recant. He spent the rest of his life under house arrest.^[12][13] During this time, he wrote Two New Sciences (1638), primarily concerning kinematics and the strength of materials, summarizing work he had done around forty years earlier.^[14]

Pierre Curie

Pierre Curie Born in Paris on 15 May 1859, Pierre Curie was the son of Eugène Curie (1827–1910), a doctor of French Catholic origin from Alsace, and Sophie-Claire Curie (née Depouilly; 1832–1897). He was educated by his father and in his early teens showed a strong aptitude for mathematics and geometry. When he was 16, he earned his Bachelor of Science in mathematics.^{[3][clarification needed]} By the age of 18, he earned his license, the equivalent of a U.S. master's degree, in physical sciences from the Faculty of Sciences at the Sorbonne, also known as the University of Paris.^[3][4][5] He did not proceed immediately to a doctorate due to lack of money. Instead, he worked as a laboratory instructor.^[6] When Pierre Curie was preparing for his Bachelor of Science degree, he worked in the laboratory of Jean-Gustave Bourbouze in the Faculty of Science.^[7] In 1895, he went on to receive his doctorate at the University of Paris.^[8] The submission material for his doctorate consisted of his research over magnetism.^[9] After obtaining his doctorate, he became professor of physics and in 1900, he became professor in the faculty of sciences.^[10]

In 1880, Pierre and his older brother Paul-Jacques (1856–1941) demonstrated that an electric potential was generated when crystals were compressed, i.e. piezoelectricity.^[11] To aid this work they invented the piezoelectric quartz electrometer.^[12] The following year they demonstrated the reverse effect: that crystals could be made to deform when subject to an electric field.^[11] Almost all digital electronic circuits now rely on this in the form of crystal oscillators.^[13] In subsequent work on magnetism Pierre Curie defined the Curie scale.^[14] This work also involved delicate equipment – balances, electrometers, etc.^[15]

Pierre Curie was introduced to Maria Skłodowska by their friend, physicist Józef Wierusz-Kowalski.^[16] Curie took her into his laboratory as his student. His admiration for her grew when he realized that she would not inhibit his research.^{[further explanation needed]} He began to regard Skłodowska as his muse.^[17] She refused his initial proposal, but finally agreed to marry him on 26 July 1895.^[6][18]

BENJAMIN FRANKLIN

 Benjamin Franklin FRS FRSA FRSE (January 17, 1706 [O.S. January 6, 1705]^{[Note 1]} – April 17, 1790) was an American polymath who was active as a writer, scientist, inventor, statesman, diplomat, printer, publisher, and political philosopher.^[1] Among the leading intellectuals of his time, Franklin was one of the Founding Fathers of the United States, a drafter and signer of the Declaration of Independence, and the first Postmaster General.^[2]

As a scientist, he was a major figure in the American Enlightenment and the history of physics for his studies of electricity, and for charting and naming the Gulf Stream current. As an inventor, he is known for the lightning rod, bifocals, and the Franklin stove, among others.^[3] He founded many civic organizations, including the Library Company, Philadelphia's first fire department,^[4] and the University of Pennsylvania.^[5] Franklin earned the title of "The First American" for his early and indefatigable campaigning for colonial unity, and as an author and spokesman in London for several colonies. As the first U.S. ambassador to France, he exemplified the emerging American nation.^[6] Franklin was foundational in defining the American ethos as a marriage of the practical values of thrift, hard work, education, community spirit, self-governing institutions, and opposition to authoritarianism both political and religious, with the scientific and tolerant values of the Enlightenment. In the words of historian Henry Steele Commager, "In Franklin could be merged the virtues of Puritanism without its defects, the illumination of the Enlightenment without its heat."^[7] Franklin has been called "the most accomplished American of his age and the most influential in inventing the type of society America would become."^[8]

ERWIN SCHRODINGER

 

Erwin Rudolf Josef Alexander Schrödinger (UK: /ˈʃrɜːdɪŋər/, US: /ˈʃroʊ-/;^[3] German: [ˈɛɐ̯vɪn ˈʃʁøːdɪŋɐ]; 12 August 1887 – 4 January 1961), sometimes written as Schroedinger or Schrodinger, was a Nobel Prize-winning Austrian and naturalized Irish physicist who developed fundamental results in quantum theory: the Schrödinger equation provides a way to calculate the wave function of a system and how it changes dynamically in time.

In addition, he wrote many works on various aspects of physics: statistical mechanics and thermodynamics, physics of dielectrics, colour theory, electrodynamics, general relativity, and cosmology, and he made several attempts to construct a unified field theory. In his book What Is Life? Schrödinger addressed the problems of genetics, looking at the phenomenon of life from the point of view of physics. He also paid great attention to the philosophical aspects of science, ancient, and oriental philosophical concepts, ethics, and religion.^[4] He also wrote on philosophy and theoretical biology. In popular culture, he is most known for his "Schrödinger's cat" thought experiment.^[5][6]

Spending most of his life as an academic with positions at various universities, Schrödinger, along with Paul Dirac, won the Nobel Prize in Physics in 1933 for his work on quantum mechanics, the same year he left Germany due to his opposition to Nazism. In his personal life, he lived with both his wife and his mistress which may have led to problems causing him to leave his position at Oxford. Subsequently, until 1938, he had a position in Graz, Austria, until the Nazi takeover when he fled, finally finding a long-term arrangement in Dublin where he remained until retirement in 1955. He died in Vienna of tuberculosis when he was 73.
