    NITROGEN IS MORE IMPORTANT THAN YOU THINK

    NITROGEN IS MORE IMPORTANT THAN YOU THINK INTRODUCTION: In this article, we discuss nitrogen its important properties, and some incidents that happened in the past with people and instruments that deal with nitrogen. So, let's start: LIQUID NITROGEN INCIDENT THAT KILLED THREE TECHNICIAN OF NASA: The First space shuttle mission was named STS-1, the first orbital mission of NASA. This mission is uniquely described in this article due to the incident in which three technicians died due to inhalation of excess nitrogen of nitrogen. IMPORTANCE OF NITROGEN: Nitrogen is a crucial element in the periodic table due to many important properties. Nitrogen is a non-toxic & colorless gas that occupies 78% of the atmosphere. HISTORY OF NITROGEN: In the past, scientists had different opinions about this gas. For example, some scientists think it was brunt air because no combination occur in the presence of this element. Some believe it is very toxic and has no life because the environment fil...

    Wave particles duality: History of Light

     Wave particle duality: History of Light

    Light is a wave. Oh! sorry particle. Oh! sorry sorry both. Light is a particle or wave you decide after reading this article and leaving your answer in the comment after reading this article.

    Light According to Newton:

    Newton which is very famous in classical mechanics. Classic mechanics without Newton is not possible. Imagine the equations of motion and laws of motion which are very useful to describe any motion of a machine or for satellites. Our current technology is based on the phenomena of classical mechanics. And this can't be ignored how useful classical mechanics are in our daily lives.

    Newton thought that light is a particle to prove this Newton gave his corpuscles theory. According to Newton's corpuscles theory, "light is a particle called corpuscles". This theory is instrumental in describing most of the phenomena of light. But in many cases it fails, for example, to describe phenomena such as interference and polarization.

    One major flaw of this is that according to the theory, light travels faster in a denser medium which the experiment proves wrong.

    By this, the theory of Newton is rejected and scientists find another theory that describes the true reality of nature.

    Light According to Huygen:

    Christian Huygen a Dutch scientist gave his wave theory of light. According to them, light is a wave that has some frequency and wavelength.

     Huygen's which says that light is a wave and represents his theory of wavefront is very useful in describing the nature of light. By that time only mechanical waves were known that's why Huygen thought that light moved in a medium called "Aether".

    Christian Huygen was a scientist at the same time as Newton but the theory of Newton was accepted more because of the contribution of Newton in physics.

    Experiment which proves on Aether medium is present:

    Due to Michelson Moley's experiment, it is proved that there is no ether-like medium is present in this universe. Michelson and Moley experiment is very important because it prove that aether like medium is not present.

    Thomas Young Experiment:

    This theory is an experiment proven by scientist Thomas Young and some other scientists who show the interference of light. 

    Young Thomas's double-slit experiment is very useful because it is the base of quantum mechanics. In this experiment, Young has two slits through which he passed coherent sources of light through which he prove that light is a wave.

    Particle Nature of light proven Experiment:

    But in the 20th century, the photoelectric effect and the Compton effect proved that light is of particle nature. Then it is proved that light behaves both as a particle and a wave.

    After this Loius De-Broglie's hypothesis was that quantum particles also behave like particles and waves.

    This is history and problems whose solution gives birth to the most powerful division of physics called "Quantum mechanics". This division led us toward the technology of quantum internet, quantum computers, and so on.

    Conclusion:

    In this article we find basic discuss the history of light. Ad highlight the problems whose solution led us toward quantum mechanics. Light is very important for us to understand behave of electric charge, magnetic charge and gravity. Because light is electromagnetic wave and while traveling through space gravity bend them and that's why it important for gravity.

    I hope you like this article. 

    Thank you for read the article.

    BOSONS: AND ITS SECRET POWER IN NATURE

    BOSONS: AND ITS SECRET POWER IN NATURE  Introduction: Nuclear and particle physics, one of the most powerful branches of physics, deals with nuclear and particles present in atoms. In Nuclear and particle physics, they are the "Standard model of particle physics". In the standard model of particle physics, two divisions divide the particle into two categories known as "Bosons and fermions" . Fermions: Fermions are the particles that are responsible for the formation of all the ordinary matter in this universe. We discuss this in detail in the previous article. Fermions Bosons: Bosons are particles that are responsible for all the basic forces in this universe. Forces are of multiple types but for all the forces we humans know scientists select four forces and say that there are "Basic forces of universe". These are as follows: 1. Weak nuclear force 2. Strong nuclear force 3. Gravitational force 4. Electromagnetic force Particles of that force: These forc...

    Quantum field theory: The most beautiful theory

    Quantum field theory: The most beautiful theory  Quantum field theory is a combination of quantum theory and field theory. It provides help in combining quantum mechanics, classical mechanics, and special relativity. Nature loves beauty. Like nature, science is also like a beautiful theory. The theory which gives answers to all the questions of nature. In the beginning, classical mechanics was the most beautiful theory because it could answer all phenomena of nature accurately. But as our technology improves we can deep dive into matter and energy. The logic of classical mechanics becomes unvaried and that is why we need another theory that can explain all the phenomena at the quantum level. Quantum mechanics was able to resolve all the questions of the quantum world and then now become the most beautiful theory of science. It explains many phenomena like  Quantum entanglement , quantum tunneling, and other such strange phenomena. But quantum mechanics also won't be able to ex...
