Who Gave Quantum Theory

Quantum theory is also known as quantum physics, quantum mechanics, matrix mechanics, and the wave mechanical model, as Quantum theory is the theoretical basis of modern physics which explains the nature and behaviour of matter and energy on a subatomic scale. It is one of the most complex but interesting theories and a branch of physics in which we study the working of the universe in a very different way.

Quantum theory was not invented by just an idea but it was the result of a series of experiments. The history of quantum mechanics is a fundamental part of the history of modern physics, as quantum theory including with theory of relativity of Einstein makes modern physics.

History of Quantum Theory

Scientific researches were already started around the 17th and 18th centuries about the wave nature of light when scientists like Robert Hooke, Christiaan Huigens, and Leonhard Euler proposed a wave theory of light. In 1803 Thomas Young describe the famous double-slit experiment. Then Michael Faraday discovered cathode ray in 1838. These studies were followed by the black-body radiation problem given by Gustav Kirchhoff in 1859, the suggestion given by Ludwig Boltzmann in 1877 that the energy state of a physical system can be discrete, and the quantum hypothesis of Max Plank in 1900 which says that any energy-radiating atomic system can be theoretically divided into several discrete "energy elements" such that each of this energy elements is proportional to the frequency with which each of them individually radiates energy as shown in the following formula

ε = hv

where 'h' is a numerical constant called plank's constant.

The foundations of quantum mechanics were established during the first half of the 20th century by Max Plank, Heisenberg, Loi de Broglie, Neils Bohr, Einstein, Arthur Campton, Erwin Schrodinger, Max Born, John Von Neumann, Paul Dirac, Fermi, Dyson, Max Von Laue, Wolfgang Pauli, Hilbert, Satyandra Nath Bose, Wilhelm Wien, Sommerfeld and others

Development of Quantum Theory

Who gave Quantum theory | Quantum Theory was proposed by | max plank

Physicist Max Plank was trying to discover the reason that the radiation from a glowing body changes its colour from red, orange and other colours and finally blue (changes of frequency) as its temperature increases. He found that by making an assumption that energy exists in individual units or packets, in the same way as a matter does, rather than a constant electromagnetic wave as assumed earlier, he was getting the answer.

Plank wrote mathematical equations along with a figure to represent these packets of energy which he called quanta. His equation explained the phenomena very well. He found that at certain discrete temperature level energy from a glowing body will occupy a different area of the colour spectrum (different frequencies). Plank already assumed that a great theory is going to emerge from these quanta. In 1918 he won noble prize also for his work in the field of quanta.

Then in 1905, Albert Einstein published a paper of photoelectric effect which is the emission of electrons when electromagnetic waves such as light hit a material. Electrons emitted by this process is called photoelectron. It advances a hypothesis that light energy is carried in discrete quantised packets. This was the further step in understanding quantum physics. In 1914 Millikan's experiment supported Einstein's model of the photoelectric effect, and in 1922 he was awarded a Nobel Prize in Physics for his achievement

Then Louis de Broglie proposed that there is no fundamental difference in the behaviour of energy and matter in 1924. On the subatomic level, it may behave as made of particles or as well as waves. This theory is known as wave-particle duality. Elementary particles of both matter and energy behave depending on the conditions as particle or wave.

Then in 1927, Warner Heisenberg proposed that the measurement of two complementary values such as position and momentum of a subatomic particle simultaneously is impossible. The more preciously one value is measured, the more flawed will be the measurement of the value of other. This theory is known as the uncertainty principle.

Planets Near To Earth | Which Planet is Nearest To Earth ? Not Venus nor Mars

Planets Near To Earth In Whole Solar System Which planet is nearest to Earth? I am sure that maximum of the people will say Venus or Mars. But actully it is wrong by some of the scientists. So first of all we have to know basically how scientists predict the distance between two planets... So what they do they just take the distance of each planet from the Sun and subtract both the result and get the distance between each planet. Example they take the distance of the Earth from the Sun and the distance of Mars from the Sun and they subtract the Earth distance from the Mars and get the distance between both the planets. But actully it is not purely correct way of determining the distance between two planets. As from high school we grown up seeing such a picture of the solar system as shown up. But that is not right. I n actual solar system planets are not align in such a way in a single line. They are like scattered marbles on the floor. Because they all have their own orbits of differ

Work And Its Types | What is Work Done In Physics

Work And Its Types You would agree that its hard work pulls a truck, to lift a stack of books, from the floor to the shelves or to pull a sofa set across the room. Indeed, all of these examples agree with the everyday meaning of work. Any activity that requires muscular or mental effort is work. In common parlance, you are working hard. All this hard work may involve very little work if we go by the scientific definition of work. In day-to-day life, we consider any useful physical or mental labour as work. Activities like playing in a field, talking with friends, humming a tune, watching a movie, attending a function are sometimes not considered to be work. What constitutes work depends on the way we define it. We use and define the term work differently in science. SCIENTIFIC CONCEPT OF WORK In physics , work has a much more precise definition. In all the examples cited above, there is something in common. In each case, you do work by exerting a force on the body while the body moves

Layers of The Earth | What are The Three Layers of The Earth explained

Layers of The Earth There is more to the Earth then what we can see on its surface. We can only see its upper part and that also only the above region of that part. In fact if you are able to hold the Earth in your hand and slice it in half, you will see that it has multiple layers. We are far excited and curious to know about space and get to know about different planets and galaxies. But our Earth alone is the center for many mysteries. Even the deepest canyon is just a scratch in front of the planet. However, advances in seismology (branch of science which studies earthquake and seismic waves) helps us to get to know many things about the inside of the Earth and we get to know that there are many layers inside our Earth. Each layer has its own properties, composition and characteristics which effects many of the processes of our planet. Starting at the center, Earth's inner layer can be classified into two types of layers' system: 1. Layers based on chemical comp

Branches of the Physics

Physics : The word physics is derived from the Latin word "physics", which means natural thing. It is the branch of science which answers how something or anything is working. It is considered with the nature and properties of matter and energy. Physics is very vast subject. It answers everything about how universe works. Studying the huge universe in a single subject is not possible, so the physics is sub-divided into so many branches. Branches of the physics 1. Classical Physics 2. Modern Physics 3. Atomic Physics 4. Nuclear Physics 5. Particle Physics 6. Molecular Physics 7. Condensed Matter Physics 8. Solid-State Physics 9. Fluid Mechanics 10. Plasma Physics 11. Geo-Physics 12. Bio-Physics 13. Chemical Physics 14. Econophysics 15. Health Physics 16. Mathematical Physics 17. Relativistic Physics 18. Engineering Physics 19. Mesoscopic Physics 20. Astro-Physics 21. Cosmology 22. Mechanics 23.

What is Physics About

What is Physics About Until the end of Eighteenth century,the mass of knowledge gained about various phenomena occurring in nature, by careful observation and close reflection, was classified into a single scheme, of study called Natural Philosophy. As knowledge increase it was found necessary to divide the study of nature into two main branches, that is:Physical Science & Biological Science. The biological sciences deal with living things whereas physical sciences are concerned with the properties and behavior of non living matter. Physics is broadly concerned with a study of all those interesting topics which deal with the laws according to which matter reacts with matter or energy, together with the related concepts of force and motion.Thus Physics deals with the fundamental properties of matter and energy.As such physics may be called as the science of matter and energy. Although Physics is one whole and cannot be compartmentalised into different part but for the sake of co
