Mathematics provides a compact and exact language used to describe the order in nature. This was noted and advocated by Pythagoras , Plato , Galileo, and Newton. Some theorists, like Hilary Putnam and Penelope Maddy , hold that logical truths, and therefore mathematical reasoning, depend on
348-488: A frame of reference that is in motion with respect to an observer; the special theory of relativity is concerned with motion in the absence of gravitational fields and the general theory of relativity with motion and its connection with gravitation . Both quantum theory and the theory of relativity find applications in many areas of modern physics. While physics itself aims to discover universal laws, its theories lie in explicit domains of applicability. Loosely speaking,
464-452: A basic awareness of the motions of the Sun, Moon, and stars. The stars and planets, believed to represent gods, were often worshipped. While the explanations for the observed positions of the stars were often unscientific and lacking in evidence, these early observations laid the foundation for later astronomy, as the stars were found to traverse great circles across the sky, which could not explain
580-573: A core vocabulary of native Prakrit and Sanskrit-derived words. However, Hindi is written in the Devanagari script and contains more direct tatsama Sanskrit -derived words than Urdu, whereas Urdu is written in the Perso-Arabic script and uses more Arabic and Persian loanwords compared to Hindi. Because of this, as well as the fact that the two registers share an identical grammar, a consensus of linguists consider them to be two standardised forms of
696-663: A covert mission to protect his daughter Sanjana, who studies at St. Paul's College in Darjeeling . Ram is initially hesitant but agrees when Bakshi informs him that Lakshman also studies in Darjeeling. General Bakshi convinces Ram to go there as a student, as he won't be able to spend enough time with Sanjana if he goes as a teacher. Ram finds it tough to adjust to college life because he is much older than everyone. He encounters Sanjana and her love interest Lucky, but both don't want to know him for this reason. A college student helps Ram hack

Many words borrowed from Persian in turn were loanwords from Arabic (e.g. muśkil "difficult", havā "air", x(a)yāl "thought", kitāb "book"). Hindi also makes extensive use of loan translation ( calqueing ) and occasionally phono-semantic matching of English . Many Hindustani words were derived from Portuguese due to interaction with colonists and missionaries: Physics Physics

Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry , and the boundaries of physics are not rigidly defined. New ideas in physics often explain the fundamental mechanisms studied by other sciences and suggest new avenues of research in these and other academic disciplines such as mathematics and philosophy. Advances in physics often enable new technologies . For example, advances in
1508-410: A part of the process of Sanskritisation , new words are coined using Sanskrit components to be used as replacements for supposedly foreign vocabulary. Usually these neologisms are calques of English words already adopted into spoken Hindi. Some terms such as dūrbhāṣ "telephone", literally "far-speech" and dūrdarśan "television", literally "far-sight" have even gained some currency in formal Hindi in
1624-544: A second language. A Hindi proponent, Indian-born Paramananda Jha , was elected vice-president of Nepal. He took his oath of office in Hindi in July 2008. This created protests in the streets for 5 days; students burnt his effigies, and there was a general strike in 22 districts. Nepal Supreme Court ruled in 2009 that his oath in Hindi was invalid and he was kept "inactive" as vice-president. An "angry" Jha said, "I cannot be compelled to take

Outside India, several other languages are recognised officially as "Hindi" but do not refer to the Standard Hindi language described here and instead descend from other nearby languages, such as Awadhi and Bhojpuri . Such languages include Fiji Hindi , which has an official status in Fiji , and Caribbean Hindustani , which
1856-465: A specific practical application as a goal, other than the deeper insight into the phenomema themselves. Applied physics is a general term for physics research and development that is intended for a particular use. An applied physics curriculum usually contains a few classes in an applied discipline, like geology or electrical engineering. It usually differs from engineering in that an applied physicist may not be designing something in particular, but rather
1972-426: A speed much less than the speed of light. These theories continue to be areas of active research today. Chaos theory , an aspect of classical mechanics, was discovered in the 20th century, three centuries after the original formulation of classical mechanics by Newton (1642–1727). These central theories are important tools for research into more specialized topics, and any physicist, regardless of their specialization,
2088-569: A standardised form of Hindustani separate from Urdu took form. In 1881, Bihar accepted Hindi as its sole official language, replacing Urdu, and thus became the first state of India to adopt Hindi. However, in 2014, Urdu was accorded second official language status in the state. After independence, the Government of India instituted the following conventions: On 14 September 1949, the Constituent Assembly of India adopted Hindi written in
2204-399: A subfield of mechanics , is used in the building of bridges and other static structures. The understanding and use of acoustics results in sound control and better concert halls; similarly, the use of optics creates better optical devices. An understanding of physics makes for more realistic flight simulators , video games, and movies, and is often critical in forensic investigations. With
2320-461: A substantial treatise on " Physics " – in the 4th century BC. Aristotelian physics was influential for about two millennia. His approach mixed some limited observation with logical deductive arguments, but did not rely on experimental verification of deduced statements. Aristotle's foundational work in Physics, though very imperfect, formed a framework against which later thinkers further developed

For example, chemistry studies properties, structures, and reactions of matter (chemistry's focus on the molecular and atomic scale distinguishes it from physics ). Structures are formed because particles exert electrical forces on each other, properties include physical characteristics of given substances, and reactions are bound by laws of physics, like conservation of energy , mass , and charge . Fundamental physics seeks to better explain and understand phenomena in all spheres, without

In an analysis of YouTube comments, Palakodety et al., identified that 52% of comments were in Romanised Hindi, 46% in English, and 1% in Devanagari Hindi. Traditionally, Hindi words are divided into five principal categories according to their etymology: Hindi has naturally inherited a large portion of its vocabulary from Shauraseni Prakrit , in the form of tadbhava words. This process usually involves compensatory lengthening of vowels preceding consonant clusters in Prakrit, e.g. Sanskrit tīkṣṇa > Prakrit tikkha > Hindi tīkhā . Much of Standard Hindi's vocabulary

Natural philosophy has its origins in Greece during the Archaic period (650 BCE – 480 BCE), when pre-Socratic philosophers like Thales rejected non-naturalistic explanations for natural phenomena and proclaimed that every event had a natural cause. They proposed ideas verified by reason and observation, and many of their hypotheses proved successful in experiment; for example, atomism
6148-601: The Standard Model of particle physics was derived. Following the discovery of a particle with properties consistent with the Higgs boson at CERN in 2012, all fundamental particles predicted by the standard model, and no others, appear to exist; however, physics beyond the Standard Model , with theories such as supersymmetry , is an active area of research. Areas of mathematics in general are important to this field, such as

Using the knowledge of previous scholars, he began to explain how light enters the eye. He asserted that the light ray is focused, but the actual explanation of how light projected to the back of the eye had to wait until 1604. His Treatise on Light explained the camera obscura , hundreds of years before
6496-579: The empirical world. This is usually combined with the claim that the laws of logic express universal regularities found in the structural features of the world, which may explain the peculiar relation between these fields. Physics uses mathematics to organise and formulate experimental results. From those results, precise or estimated solutions are obtained, or quantitative results, from which new predictions can be made and experimentally confirmed or negated. The results from physics experiments are numerical data, with their units of measure and estimates of

There is also considerable interdisciplinarity , so many other important fields are influenced by physics (e.g., the fields of econophysics and sociophysics ). Physicists use the scientific method to test the validity of a physical theory . By using a methodical approach to compare the implications of a theory with the conclusions drawn from its related experiments and observations, physicists are better able to test
8584-429: The development of modern physics in the 20th century. Modern physics began in the early 20th century with the work of Max Planck in quantum theory and Albert Einstein 's theory of relativity. Both of these theories came about due to inaccuracies in classical mechanics in certain situations. Classical mechanics predicted that the speed of light depends on the motion of the observer, which could not be resolved with
8700-407: The development of new experiments (and often related equipment). Physicists who work at the interplay of theory and experiment are called phenomenologists , who study complex phenomena observed in experiment and work to relate them to a fundamental theory . Theoretical physics has historically taken inspiration from philosophy; electromagnetism was unified this way. Beyond the known universe,
8816-682: The errors in the measurements. Technologies based on mathematics, like computation have made computational physics an active area of research. Ontology is a prerequisite for physics, but not for mathematics. It means physics is ultimately concerned with descriptions of the real world, while mathematics is concerned with abstract patterns, even beyond the real world. Thus physics statements are synthetic, while mathematical statements are analytic. Mathematics contains hypotheses, while physics contains theories. Mathematics statements have to be only logically true, while predictions of physics statements must match observed and experimental data. The distinction
8932-415: The field. His approach is entirely superseded today. He explained ideas such as motion (and gravity ) with the theory of four elements . Aristotle believed that each of the four classical elements (air, fire, water, earth) had its own natural place. Because of their differing densities, each element will revert to its own specific place in the atmosphere. So, because of their weights, fire would be at
9048-404: The film was revived in 2003, Hrithik Roshan , Farhan Akhtar , and Sohail Khan were considered for Lucky's role. Due to unknown reasons, none of the three accepted the film; Zayed Khan was later signed. Ameesha Patel was offered Sanju's role but rejected the character due to date issues, as did then-newcomer Ayesha Takia when she was also approached who also declined, after which Amrita Rao
9164-472: The film, Major Ram Prasad Sharma is sent on a covert mission to pose as a college student and protect the general 's daughter from a dangerous rogue soldier. Development for the film began as early as 2001; however, it faced a number of delays during production. Main Hoon Na is notable for approaching the Indo-Pakistani conflict from a neutral perspective. Filming took place at St. Paul's School and
9280-531: The last 125 years, there are no academic studies of any of them – of their use in South Africa, their evolution and current decline. Hindi is adopted as the third official court language in the Emirate of Abu Dhabi . As a result of this status, the Indian workforce in UAE can file their complaints to the labour courts in the country in their own mother-tongue. Hindi is the lingua franca of northern India (which contains
9396-400: The latter include such branches as hydrostatics , hydrodynamics and pneumatics . Acoustics is the study of how sound is produced, controlled, transmitted and received. Important modern branches of acoustics include ultrasonics , the study of sound waves of very high frequency beyond the range of human hearing; bioacoustics , the physics of animal calls and hearing, and electroacoustics ,
9512-412: The latter's hand grenade. Lakshman helps Ram escape from the ensuing explosion from aboard a helicopter and the two happily embrace as brothers. Project Milaap is a success and all the prisoners are exchanged triumphantly. Ram and Lakshman immerse their father's ashes together as Madhu tearfully looks on. Finally, Lakshman and Ram graduate from the university, and the entire university rejoices. The film
9628-490: The laws of classical physics accurately describe systems whose important length scales are greater than the atomic scale and whose motions are much slower than the speed of light. Outside of this domain, observations do not match predictions provided by classical mechanics. Einstein contributed the framework of special relativity, which replaced notions of absolute time and space with spacetime and allowed an accurate description of systems whose components have speeds approaching
9744-412: The manipulation of audible sound waves using electronics. Optics, the study of light, is concerned not only with visible light but also with infrared and ultraviolet radiation , which exhibit all of the phenomena of visible light except visibility, e.g., reflection, refraction, interference, diffraction, dispersion, and polarization of light. Heat is a form of energy, the internal energy possessed by
9860-696: The modern development of photography. The seven-volume Book of Optics ( Kitab al-Manathir ) influenced thinking across disciplines from the theory of visual perception to the nature of perspective in medieval art, in both the East and the West, for more than 600 years. This included later European scholars and fellow polymaths, from Robert Grosseteste and Leonardo da Vinci to Johannes Kepler . The translation of The Book of Optics had an impact on Europe. From it, later European scholars were able to build devices that replicated those Ibn al-Haytham had built and understand
9976-641: The oath now in Nepali. I might rather take it in English." Hindi is a protected language in South Africa . According to the Constitution of South Africa , the Pan South African Language Board must promote and ensure respect for Hindi along with other languages. According to a doctoral dissertation by Rajend Mesthrie in 1985, although Hindi and other Indian languages have existed in South Africa for
10092-569: The official language of the imperial court during the reign of Shah Jahan . It is recorded that Emperor Aurangzeb spoke in Hindvi . The Hindustani vernacular became an expression of Indian national unity during the Indian Independence movement , and continues to be spoken as the common language of the people of the northern Indian subcontinent, which is reflected in the Hindustani vocabulary of Bollywood films and songs. Standard Hindi
10208-462: The other Philoponus' criticism of Aristotelian principles of physics served as an inspiration for Galileo Galilei ten centuries later, during the Scientific Revolution . Galileo cited Philoponus substantially in his works when arguing that Aristotelian physics was flawed. In the 1300s Jean Buridan , a teacher in the faculty of arts at the University of Paris , developed the concept of impetus. It
10324-459: The other, you will see that the ratio of the times required for the motion does not depend on the ratio of the weights, but that the difference in time is a very small one. And so, if the difference in the weights is not considerable, that is, of one is, let us say, double the other, there will be no difference, or else an imperceptible difference, in time, though the difference in weight is by no means negligible, with one body weighing twice as much as
10440-572: The particles of which a substance is composed; thermodynamics deals with the relationships between heat and other forms of energy. Electricity and magnetism have been studied as a single branch of physics since the intimate connection between them was discovered in the early 19th century; an electric current gives rise to a magnetic field , and a changing magnetic field induces an electric current. Electrostatics deals with electric charges at rest, electrodynamics with moving charges, and magnetostatics with magnetic poles at rest. Classical physics
10556-483: The place of the English borrowings (ṭeli)fon and ṭīvī . Hindi also features significant Persian influence, standardised from spoken Hindustani . Early borrowings, beginning in the mid-12th century, were specific to Islam (e.g. Muhammad , Islām ) and so Persian was simply an intermediary for Arabic. Later, under the Delhi Sultanate and Mughal Empire , Persian became the primary administrative language in
10672-596: The positions of the planets . According to Asger Aaboe , the origins of Western astronomy can be found in Mesopotamia , and all Western efforts in the exact sciences are descended from late Babylonian astronomy . Egyptian astronomers left monuments showing knowledge of the constellations and the motions of the celestial bodies, while Greek poet Homer wrote of various celestial objects in his Iliad and Odyssey ; later Greek astronomers provided names, which are still used today, for most constellations visible from
10788-522: The progressive use of Hindi language and impose restrictions on the use of the English language by the union government. In practice, the official language commissions are constantly endeavouring to promote Hindi but not imposing restrictions on English in official use by the union government. At the state level, Hindi is the official language of the following Indian states: Bihar , Chhattisgarh , Haryana , Himachal Pradesh , Jharkhand , Madhya Pradesh , Rajasthan , Uttar Pradesh and Uttarakhand . Hindi
10904-495: The same language, Hindustani or Hindi-Urdu. Hindi is the most commonly used scheduled language in India and is one of the two official languages of the union , the other being English. Urdu is the national language and lingua franca of Pakistan and is one of 22 scheduled languages of India , also having official status in Uttar Pradesh , Jammu and Kashmir , Delhi , Telangana , Andhra Pradesh and Bihar . Hindi
11020-440: The speed being proportional to the weight and the speed of the object that is falling depends inversely on the density object it is falling through (e.g. density of air). He also stated that, when it comes to violent motion (motion of an object when a force is applied to it by a second object) that the speed that object moves, will only be as fast or strong as the measure of force applied to it. The problem of motion and its causes
11136-412: The speed of light. Planck, Schrödinger, and others introduced quantum mechanics, a probabilistic notion of particles and interactions that allowed an accurate description of atomic and subatomic scales. Later, quantum field theory unified quantum mechanics and special relativity. General relativity allowed for a dynamical, curved spacetime, with which highly massive systems and the large-scale structure of
11252-412: The study of probabilities and groups . Physics deals with a wide variety of systems, although certain theories are used by all physicists. Each of these theories was experimentally tested numerous times and found to be an adequate approximation of nature. For instance, the theory of classical mechanics accurately describes the motion of objects, provided they are much larger than atoms and moving at
11368-718: The surrounding state of West Bengal . The film is also the first production of Red Chillies Entertainment. Main Hoon Na was released on 30 April 2004 to positive reviews from critics and became a commercial success by grossing ₹84 crore, thus becoming the second highest-grossing Indian film of 2004 , only surpassed by another Shah Rukh Khan-starrer Veer-Zaara . At the 50th Filmfare Awards , Main Hoon Na received 12 nominations, including Best Film , Best Director (Farah), Best Actor (Shah Rukh), Best Supporting Actress (Rao), Best Supporting Actor (Zayed) and Best Villain (Shetty), winning Best Music Director ( Anu Malik ). A snippet of "Lament" from Light of Aiden (Celtic Version)
11484-444: The top, air underneath fire, then water, then lastly earth. He also stated that when a small amount of one element enters the natural place of another, the less abundant element will automatically go towards its own natural place. For example, if there is a fire on the ground, the flames go up into the air in an attempt to go back into its natural place where it belongs. His laws of motion included: that heavier objects will fall faster,
11600-471: The transition from Middle Indo-Aryan to Hindi are: During the period of Delhi Sultanate in medieval India , which covered most of today's north India, eastern Pakistan, southern Nepal and Bangladesh and which resulted in the contact of Hindu and Muslim cultures , the Sanskrit and Prakrit base of Old Hindi became enriched with loanwords from Persian , evolving into the present form of Hindustani. Hindi achieved prominence in India after it became
11716-423: The understanding of electromagnetism , solid-state physics , and nuclear physics led directly to the development of technologies that have transformed modern society, such as television, computers, domestic appliances , and nuclear weapons ; advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus . The word physics comes from
11832-423: The universe can be well-described. General relativity has not yet been unified with the other fundamental descriptions; several candidate theories of quantum gravity are being developed. Physics, as with the rest of science, relies on the philosophy of science and its " scientific method " to advance knowledge of the physical world. The scientific method employs a priori and a posteriori reasoning as well as
11948-476: The university, though his revelation moves them to tears. Later, Raghavan holds the university hostage, demanding the cancellation of Project Milaap along with the return of Captain Khan and Ram as hostages in exchange for all the students' and teachers' lives. Upon being informed, Ram immediately returns to the university. Before fully entering the hostage situation, Ram encounters Madhu and apologizes. Knowing what Ram
12064-573: The use of Bayesian inference to measure the validity of a given theory. Study of the philosophical issues surrounding physics, the philosophy of physics , involves issues such as the nature of space and time , determinism , and metaphysical outlooks such as empiricism , naturalism , and realism . Many physicists have written about the philosophical implications of their work, for instance Laplace , who championed causal determinism , and Erwin Schrödinger , who wrote on quantum mechanics. The mathematical physicist Roger Penrose has been called
12180-988: The validity of a theory in a logical, unbiased, and repeatable way. To that end, experiments are performed and observations are made in order to determine the validity or invalidity of a theory. A scientific law is a concise verbal or mathematical statement of a relation that expresses a fundamental principle of some theory, such as Newton's law of universal gravitation. Theorists seek to develop mathematical models that both agree with existing experiments and successfully predict future experimental results, while experimentalists devise and perform experiments to test theoretical predictions and explore new phenomena. Although theory and experiment are developed separately, they strongly affect and depend upon each other. Progress in physics frequently comes about when experimental results defy explanation by existing theories, prompting intense focus on applicable modelling, and when new theories generate experimentally testable predictions , which inspire
12296-573: The way vision works. Physics became a separate science when early modern Europeans used experimental and quantitative methods to discover what are now considered to be the laws of physics . Major developments in this period include the replacement of the geocentric model of the Solar System with the heliocentric Copernican model , the laws governing the motion of planetary bodies (determined by Kepler between 1609 and 1619), Galileo's pioneering work on telescopes and observational astronomy in
12412-399: The works of many scientists like Ibn Sahl , Al-Kindi , Ibn al-Haytham , Al-Farisi and Avicenna . The most notable work was The Book of Optics (also known as Kitāb al-Manāẓir), written by Ibn al-Haytham, in which he presented the alternative to the ancient Greek idea about vision. In his Treatise on Light as well as in his Kitāb al-Manāẓir , he presented a study of the phenomenon of
12528-668: The world including first and second language speakers. Hindi is the fastest growing language of India , followed by Kashmiri , Meitei , Gujarati and Bengali according to the 2011 census of India . The term Hindī originally was used to refer to inhabitants of the Indo-Gangetic Plain . It was borrowed from Classical Persian هندی Hindī ( Iranian Persian pronunciation: Hendi ), meaning ' of or belonging to Hind (India) ' (hence, ' Indian ' ). Another name Hindavī ( हिन्दवी ) or Hinduī ( हिन्दुई ) (from Persian هندوی 'of or belonging to
12644-538: Was a step toward the modern ideas of inertia and momentum. Islamic scholarship inherited Aristotelian physics from the Greeks and during the Islamic Golden Age developed it further, especially placing emphasis on observation and a priori reasoning, developing early forms of the scientific method . The most notable innovations under Islamic scholarship were in the field of optics and vision, which came from
12760-555: Was envisioned that Hindi would become the sole working language of the Union Government by 1965 (per directives in Article 344 (2) and Article 351), with state governments being free to function in the language of their own choice. However, widespread resistance to the imposition of Hindi on non-native speakers, especially in South India (such as those in Tamil Nadu ) led to the passage of
12876-554: Was finalized for the role. Shah Rukh Khan asked Farah Khan to approach Kamal Haasan , suggesting that Haasan owed him a favor for his role in Hey Ram (2000). Haasan heard the script but turned down the role citing that it would portray him as an anti-national. Main Hoon Na received positive reviews from critics. Taran Adarsh of Bollywood Hungama wrote " Main Hoon Na reinforces your faith in Bollywood commercial cinema. The film
12992-503: Was found to be correct approximately 2000 years after it was proposed by Leucippus and his pupil Democritus . During the classical period in Greece (6th, 5th and 4th centuries BCE) and in Hellenistic times , natural philosophy developed along many lines of inquiry. Aristotle ( Greek : Ἀριστοτέλης , Aristotélēs ) (384–322 BCE), a student of Plato , wrote on many subjects, including
13108-417: Was not scrutinized until Philoponus appeared; unlike Aristotle, who based his physics on verbal argument, Philoponus relied on observation. On Aristotle's physics Philoponus wrote: But this is completely erroneous, and our view may be corroborated by actual observation more effectively than by any sort of verbal argument. For if you let fall from the same height two weights of which one is many times as heavy as
13224-538: Was planned by Farah Khan and Shahrukh Khan in 2001. The shooting of the film had to begin in October 2001 but later that year, Shahrukh Khan got badly injured while shooting an action sequence for Shakti: The Power (2002) due to which he suffered pain in filming for his other projects. He was later sent to the UK for treatment and the film was subsequently shelved. The film was later revived in 2003 after Shahrukh Khan came back from
13340-498: Was positive of the performances. Main Hoon Na was the second-highest grossing Indian film of 2004 behind Veer-Zaara (also a Shahrukh Khan -starrer set against India-Pakistan backdrop). It made ₹ 480 million (US$ 5.8 million) in India and an additional ₹ 19 million (US$ 230,000) in the overseas market. The music was composed by Anu Malik . The lyrics were provided by Javed Akhtar . The soundtrack earned Malik his second Filmfare Award for Best Music Director . According to
13456-531: Was studied carefully, leading to the philosophical notion of a " prime mover " as the ultimate source of all motion in the world (Book 8 of his treatise Physics ). The Western Roman Empire fell to invaders and internal decay in the fifth century, resulting in a decline in intellectual pursuits in western Europe. By contrast, the Eastern Roman Empire (usually known as the Byzantine Empire ) resisted
