Q:Information: - Jean-Baptiste le Rond d'Alembert (16 November 1717 29 October 1783) was a French mathematician, mechanician, physicist, philosopher, and music theorist. Until 1759 he was also co-editor with Denis Diderot of the "Encyclopedie". D'Alembert's formula for obtaining solutions to the wave equation is named after him. The wave equation is sometimes referred to as d'Alembert's equation. - France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux. - Jean - Baptiste le Rond d'Alembert ( / dlmbr / ; French : ( batist l dalb ) ; 17 November 1717 -- 29 October 1783 ) was a French mathematician , mechanician , physicist , philosopher , and music theorist .

The wave equation is sometimes referred to as d'Alembert 's equation . - Pythagoras of Samos ( or simply ; in Ionian Greek) was an Ionian Greek philosopher, mathematician, and the putative founder of the movement called Pythagoreanism. Most of the information about Pythagoras was written down centuries after he lived, so very little reliable information is known about him. He was born on the island of Samos, and travelled, visiting Egypt and Greece, and maybe India. Around 530 BC, he moved to Croton, in Magna Graecia, and there established some kind of school or guild. In 520 BC, he returned to Samos. - A philosopher is someone who practices philosophy, which involves rational inquiry into areas that are outside of either theology or science. The term "philosopher" comes from the Ancient Greek ("philosophos") meaning "lover of wisdom". The coining of the term has been attributed to the Greek thinker Pythagoras (6th century BC). - Encyclopedie, ou dictionnaire raisonne des sciences, des arts et des metiers ("Encyclopaedia, or a Systematic Dictionary of the Sciences, Arts, and Crafts") was a general encyclopedia published in France between 1751 and 1772, with later supplements, revised editions, and translations. It had many writers, known as the "Encyclopedistes". It was edited by Denis Diderot and, until 1759, co-edited by Jean le Rond d'Alembert. - Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight. Visible light is usually defined as having wavelengths in the range of 400700 nanometres (nm), or 4.00 10 to 7.00 10m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). This wavelength means a frequency range of roughly 430750 terahertz (THz). - The Encyclopedistes were members of the Societe des gens de lettres, a French writer's society, who contributed to the development of the "Encyclopedie" from June 1751 to December 1765 under editors Denis Diderot and Jean le Rond d'Alembert. The composition of the 17 volumes of text and 11 volumes of plates of the "Encyclopedie" was the work of over 150 authors belonging, in large part, to the intellectual group known as the philosophes. They promoted the advancement of science and secular thought and supported tolerance, rationality, and open-mindedness of the Enlightenment. - The wave equation is an important second-order linear partial differential equation for the description of wavesas they occur in physicssuch as sound waves, light waves and water waves. It arises in fields like acoustics, electromagnetics, and fluid dynamics. - Philosophy (from Greek , "philosophia", literally "love of wisdom") is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. The term was probably coined by Pythagoras (c. 570 c. 495 BC). Philosophical methods include questioning, critical discussion, rational argument and systematic presentation. Classic philosophical questions include: Is it possible to know anything and to prove it? What is most real? However, philosophers might also pose more practical and concrete questions such as: Is there a best way to live? Is it better to be just or unjust (if one can get away with it)? Do humans have free will? - Denis Diderot (5 October 171331 July 1784) was a French philosopher, art critic, and writer. He was a prominent figure during the Enlightenment and is best known for serving as co-founder, chief editor, and contributor to the "Encyclopedie" along with Jean le Rond d'Alembert. - In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a transmission medium such as air or water. In physiology and psychology, sound is the "reception" of such waves and their "perception" by the brain. Humans can hear sound waves with frequencies between about 20Hz and 20kHz. Sound above 20kHz is ultrasound and below 20Hz is infrasound. Other animals have different hearing ranges. - The 6th century BC started the first day of 600 BC and ended the last day of 501 BC.
