A physicist is a scientist who specializes in the field of physics , which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena , and usually frame their understanding in mathematical terms. They work across a wide range of research fields , spanning all length scales: from sub-atomic and particle physics , through biological physics , to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena.

Zoological Museum of Naples The Zoological Museum of Naples , located in Naples , south Italy , was founded by Gioacchino Murat in 1811. The first curator was Luigi Petagna . The founding collections were those of the Royal Bourbon Museum and the private collection of Giuseppe Saverio Poli . Later curators were: Giosuè Sangiovanni , Achille Costa (from 1860), Francesco Saverio Monticelli (from 1900).
224-683: The Institute of Physics . It is denoted by the postnominals "CPhys". Achieving chartered status in any profession denotes to the wider community a high level of specialised subject knowledge and professional competence. According to the Institute of Physics, holders of the award of the Chartered Physicist (CPhys) demonstrate the "highest standards of professionalism, up-to-date expertise, quality and safety" along with "the capacity to undertake independent practice and exercise leadership" as well as "commitment to keep pace with advancing knowledge and with
252-539: The Islamic medieval period , which saw the development of scientific methodology emphasising experimentation , such as the work of Ibn al-Haytham (Alhazen) in the 11th century. The modern scientific worldview and the bulk of physics education can be said to flow from the scientific revolution in Europe, starting with the work of astronomer Nicolaus Copernicus leading to the physics of Galileo Galilei and Johannes Kepler in
280-550: The 1770s, was known by his friends as the Museo Poliano . They included minerals, fossils, mollusc shells, corals, sponges, insects (including a fine collection from Surinam), weapons, clothing, indigenous tools, paintings and scientific instruments. The more valuable items in the collection were looted by French troops during the conquest of Naples in 1806, and he later turned to collecting coins, medals and antiquities. After his death, these were curated by Delle Chiaie and acquired by
308-579: The 19th century. Many physicists contributed to the development of quantum mechanics in the early-to-mid 20th century. New knowledge in the early 21st century includes a large increase in understanding physical cosmology . The broad and general study of nature, natural philosophy , was divided into several fields in the 19th century, when the concept of "science" received its modern shape. Specific categories emerged, such as "biology" and "biologist", "physics" and "physicist", "chemistry" and "chemist", among other technical fields and titles. The term physicist

He later became professor of experimental physics at the University of Naples , of which he was first director of physics. His best known work is represented by the six volumes of the Elements of Experimental Physics , which had numerous editions and reprints and
364-507: The Royal Bourbon Museum and, along with his natural history collection, formed the foundation of the Zoological Museum of Naples . Physicist Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applied physics or engineering physics ). The study and practice of physics is based on an intellectual ladder of discoveries and insights from ancient times to
392-725: The academy, visiting many seats of learning in Germany, France, England and the Netherlands and meeting naturalists and scientists. This enabled him to equip the physics department with the most modern equipment. He became friends with the Scottish physician and collector William Hunter , who encouraged him to study the molluscs of the Mediterranean, which were then very poorly known. He also added to his personal collection of natural history objects and archaeological artifacts. Later he taught physics at

The work on mechanics , along with a mathematical treatment of physical systems, was further developed by Christiaan Huygens and culminated in Newton's laws of motion and Newton's law of universal gravitation by the end of the 17th century. The experimental discoveries of Faraday and the theory of Maxwell's equations of electromagnetism were developmental high points during
532-735: The increasing expectations and requirements for which any profession must take responsibility". Chartered Physicist is considered to be equal in status to Chartered Engineer, which the IoP also awards as a member of the Engineering Council UK, and other chartered statuses in the UK. It is also considered a "regulated profession" under the European professional qualification directives. The Canadian Association of Physicists can appoint an official designation called Professional Physicist ( P. Phys. ), similar to

He briefly worked as a doctor in Molfetta, but in 1790 he moved to Naples to teach history and geography at the Nunziatella Military School , for which, once he became commander, with the rank of lieutenant colonel, he took care of the department of physics. In 1775 he toured Europe on behalf of
728-738: Was coined by William Whewell (also the originator of the term "scientist") in his 1840 book The Philosophy of the Inductive Sciences . A standard undergraduate physics curriculum consists of classical mechanics , electricity and magnetism , non-relativistic quantum mechanics , optics , statistical mechanics and thermodynamics , and laboratory experience. Physics students also need training in mathematics ( calculus , differential equations , linear algebra , complex analysis , etc.), and in computer science . Any physics-oriented career position requires at least an undergraduate degree in physics or applied physics, while career options widen with
756-460: Was modified and integrated on several occasions by Poli himself. The work was used by Alessandro Volta for his university lectures and was even read and studied by Giacomo Leopardi . It has also been criticized by Vincenzo Dandolo , as in the 1790s it still introduced phlogiston in the part relating to chemical reactions (volume III), which had already been widely recognized as non-existent by most scientists (the part relating to chemical reactions
784-484: Was preceded by an introduction by Dandolo himself, which explained the partial defects of the work). The changes made in the editions of the following years were to deny the existence of phlogiston even in his own work. Thanks to his many travels, which put him in contact and correspondence with authoritative exponents of the international scientific world, he published numerous essays on various topics: not only relating to physics, but also to meteorology, in particular with
