  • Deodatta V. Shenai-Khatkhate:

    I still remember two life-sized marble statues of two great scientists in the corridor of Manchester Town Hall, which I saw many years ago. One of them is of John Dalton, the founder of modern Chemistry and the Atomic Theory, while the second statue is of James Prescott Joule, the founder of modern Physics and the discoverer of the Law of Conservation of Energy. I consider myself very fortunate to be the student of the University of Manchester, the home of great scientists, Dalton and Joule. And most importantly, I am proud to be the recipient of Dalton Chemical Research Scholarship that enabled me to obtain my Ph.D. I am thankful to The University of Manchester as much as to John Dalton’s Trust Foundation, for the greatest educational experience of my life.

  • Medieval European And Islamic

    The Western Roman Empire fell in the fifth century, and this resulted in a decline in intellectual pursuits in the western part of Europe. By contrast, the Eastern Roman Empire resisted the attacks from the barbarians, and continued to advance various fields of learning, including physics.

    In the sixth century, Isidore of Miletus created an important compilation of Archimedes‘ works that are copied in the Archimedes Palimpsest.

    In sixth-century Europe John Philoponus, a Byzantine scholar, questioned Aristotle‘s teaching of physics and noted its flaws. He introduced the theory of impetus. Aristotle’s physics 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:

    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 was a step toward the modern ideas of inertia and momentum.

    What Are The Three Laws Of Physics

    The three laws of physics, as they are commonly referred to, are known formally as Newton’s laws of motion. They are considered the basis of classical mechanics. Newton’s laws describe the motion of a body upon which forces may act and which may exert forces on other bodies.

    When we speak of bodies, we are not speaking of actual human bodies , but of any piece of matter upon which a force may act. Newton’s three laws are outlined below.

    Definition Of Physics By The Oxford English Dictionary

    “The branch of science concerned with the nature and properties of matter and energy. The subject matter of physics includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms.”

    Another definition by the digital encyclopedia Microsoft Encarta describes physics as:

    Physics Uses The Scientific Method

    Is physics mostly math?

    Physics uses the scientific method. That is, data from experiments and observations are collected. Theories which attempt to explain these data are produced. Physics uses these theories to not only describe physical phenomena, but to model physical systems and predict how these physical systems will behave. Physicists then compare these predictions to observations or experimental evidence to show whether the theory is right or wrong.

    The theories that are well supported by data and are especially simple and general are sometimes called scientific laws. Of course, all theories, including those known as laws, can be replaced by more accurate and more general laws, when a disagreement with data is found.

    What Are The Four Laws Of Thermodynamics

    The four laws of thermodynamics are as follows.

  • If two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other. This law helps define the concept of temperature.
  • When energy passes, as work, as heat, or with matter, into or out from a system, the system’s internal energy changes in accord with the law of conservation of energy. Equivalently, perpetual motion machines of the first kind are impossible.
  • In a natural thermodynamic process, the sum of the entropies of the interacting thermodynamic systems increases. Equivalently, perpetual motion machines of the second kind are impossible.
  • The entropy of a system approaches a constant value as the temperature approaches absolute zero. With the exception of non-crystalline solids , the entropy of a system at absolute zero is typically close to zero, and is equal to the natural logarithm of the product of the quantum ground states.

    Physics In The Medieval Islamic World

    Islamic scholars continued to study Aristotelian physics during the Islamic Golden Age. One main contribution was to observational astronomy. Some, like Ibn Sahl, Al-Kindi, Ibn al-Haytham, Al-Farisi and Avicenna, worked on optics and vision. In The Book of Optics, Ibn al-Haytham rejected previous Greek ideas concerning vision and proposed a new theory. He studied how light enters the eye, and developed the camera obscura. European scientists later built eyeglasses, magnifying glasses, telescopes, and cameras from this book.

    What Is The Theory Of Relativity

    Did you know the actual meaning of the word " Physics" ? # ...

    Albert Einstein’s theory of relativity is one of the most important discoveries of the contemporary age, and states that the laws of physics are the same for all non-accelerating observers. As a result of this discovery, Einstein was able to confirm that space and time are interwoven in a single continuum known as space-time. As such, events that occur at the same time for one observer could occur at different times for another.

    Einstein’s theory of relativity is summarized in the formula:

    E = mc^2

    In this equation, “E” represents energy, “m” represents mass, and “c” represents the speed of light.

    The most curious mind out of all the species is the mind of homosapiens. Humans are always curious about the nature around them and the magic laws on which it functions. The sun always rises in the east and sets in the west, the moon appears at night and the sun appears in the day, and so on. All these questions not on make humans curious but make them think and discover about the different theories of nature and by doing so, humans soon started discovering physics in order to discover the world and its mystery. Lets learn what is physics in more detail,

    Applications Of Multipole Moments

    The multipole expansion applies to 1/r scalar potentials, examples of which include the electric potential and the gravitational potential. For these potentials, the expression can be used to approximate the strength of a field produced by a localized distribution of charges by calculating the first few moments. For sufficiently large r, a reasonable approximation can be obtained from just the monopole and dipole moments. Higher fidelity can be achieved by calculating higher order moments. Extensions of the technique can be used to calculate interaction energies and intermolecular forces.

    The technique can also be used to determine the properties of an unknown distribution . Measurements pertaining to multipole moments may be taken and used to infer properties of the underlying distribution. This technique applies to small objects such as molecules,but has also been applied to the universe itself, being for example the technique employed by the WMAP and Planck experiments to analyze the cosmic microwave background radiation.

    The history of nuclear physics as a distinct field from atomic physics begins with the discovery of radioactivity by Henri Becquerel in 1896. The discovery of the electron one year later indicated that the atom had an internal structure.

    With this, studies began on the nuclei of atoms, thus nuclear physics was born.

    Fundamental Forces In Nature

    What is PHYSICS? What does PHYSICS mean? PHYSICS meaning, definition & explanation

    Force is seen and experienced on a daily basis and is available on both macroscopic and microscopic levels. At a macroscopic level, apart from gravitational force, several kinds of forces are experienced, for instance, muscular force, contact forces, the elongation or compression of elastics, etc. On a microscopic level, there are electric and magnetic forces, nuclear forces, etc. Although, it was further observed that most of the forces defined or explained are derived from four fundamental forces. The four fundamental forces in nature are,

    • Gravitational Force: It is the mutual force that occurs between two objects by the virtue of their masses. Gravitational force is a universal force. The formula for gravitational force is,

    FG = /r2

    M1, M2 = Masses1 and 2.

    r = distance between the center of the masses.

    Scope And Excitement Of Physics

    The scope of physics can be majorly understood by looking at its sub-divisions. There are basically two types of studies in physics, macroscopic physics, and microscopic physics. Macroscopic physics deals with phenomena on a terrestrial, astronomical scale, while microscopic physics deals with the phenomenon on an atomic, molecular, or nuclear scale. The macroscopic study is done mostly in classical physics that includes subjects like mechanics, thermodynamics, etc. The microscopic study is the study of the structure of the atom, etc. Classical physics is unable to contribute in this field and currently, quantum theory is referred for the microscopic level studies.

    Therefore, it can be said that the scope of physics is really very vast. The study covers a plethora of physical quantities like length, mass, time, energy, etc. From the study of smallest quantities to the study of the quantities on an astronomical level .

    A major science dealing with the fundamental constituents of the universe, the forces they exert on one another, and the results produced by these forces. Sometimes in modern physics a more sophisticated approach is taken that incorporates elements of the three areas listed above it relates to the laws of symmetry and conservation, such as those pertaining to energy, momentum, charge, and parity.

    What these definitions indicate is that physics is a branch of science that deals with the properties of matter and energy and the relationship between them. It also tries to explain the material world and the natural phenomena of the universe.

    The scope of physics is very wide and vast. It deals with not only the tinniest particles of atoms, but also natural phenomenon like the galaxy, the milky way, solar and lunar eclipses, and more. While it is true that physics is a branch of science, there are many sub-branches within the field of physics. In this article, we will explore each of them in depth.

    Who Discovered Thermodynamics

    The field of thermodynamics was developed from the work of Nicolas Léonard Sadi Carnot who believed that engine efficiency was the key that could help France win the Napoleonic Wars.

    The Scottish physicist Lord Kelvin was the first to come up with a concise definition of thermodynamics. His definition stated:

    “Thermo-dynamics is the subject of the relation of heat to forces acting between contiguous parts of bodies, and the relation of heat to electrical agency.”

    What Is Quantum Theory

    Discovered by Max Plank in 1900, quantum theory is the theoretical basis of modern physics that explains the nature and behaviour of matter and energy on the atomic and subatomic level. The nature and behaviour of matter and energy at that level is sometimes referred to as quantum physics and quantum mechanics.

    Plank discovered that energy exists in individual units in the same way that matter does, rather than just as a constant electromagnetic wave. Thus, energy was quantifiable. The existence of these units, called quanta, act as the basis of Plank’s quantum theory.

    Nuclear physicists examine only the nucleus, not the atom as a whole.
