    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...

    Black body radiation: A Phenomena which change physics forever

    Black Body Radiation: A Phenomena which change physics forever

    Introduction:

    In the beginning, classical physics was able to predict everything accurately and we are heavily dependent on it for everything. But it said that nothing is perfect. Likewise, the case of classical physics which fails to explain certain phenomena. The one such case that classical physics can't explain is "BLACK BODY RADIATION".

    It is said that everybody emits electromagnetic radiation above absolute zero. But scientists are very curious. They try to imagine a body that emits every wavelength of electromagnetic radiation or absorbs every kind of wavelength. This body was called "BLACK BODY".

    Point to be noted:

    There is one point that you must keep in mind:

    1. In this universe no perfect black body is present.

    Example:

    Let's imagine a bulb with a platinum filament if we increase the voltage temperature of the filament increase and when the temperature of the filament reaches 500 degrees Celsius the wire becomes dull red, if we increase the temperature up to 900 degrees Celsius then its color become cherry red and so on to white at 1600 degree Celsius.

    This is also related to the black body; by this, we can predict the temperature of any star by observing the color it emits. 

    How cool right!

    Explanation of Classical Physics and the Beginning of Quantum Physics:

    According to classical physics objects that have temperatures up to higher than a certain limit emit an infinite amount of energy. This is also known as an "ultraviolet catastrophe".

    To explain this Max Plank came and solved this by assuming that light is not in continuous form but travels in the discontinuous form. And by this, he proves the curve accurately.

    This is the moment by which the rise of quantum physics began and this thing changed the civilization of humanity completely.

    By quantum physics, we explain many mysteries and due to this, our technology improve. Science is really beautiful in all the things that humanity has because it becomes perfect with time. In the era of Quantum physics, humanity changed completely and with this increasing amount of knowledge, we built quantum computers and much more technology soon like quantum internet.

    Black body radiation is a significant phenomenon that increases our understanding of the universe and revolutionizes our technology. Black body radiation helps us to understand quantum physics and is also very useful in cosmology and in-camera like thermal cameras.

    In Cosmology:

    In cosmology, scientists and astronomers can predict the energy of a star, its temperature, and so many details.

    For example, cosmologists with the details of which wavelength stars emit predict their temperature, luminosity, and power by the equations of the black body.

    In technology:

    In technology, the knowledge of the black body helps us to understand many things by which we built thermal cameras, infrared thermography, medical imaging, temperature sensors, and many more such things.

    Conclusions:

    Black body radiation is a critical phenomena in physics that change the whole world of physics and science completely. That is why we built such power devices that can measure the temperature and other factors of stars at great distances accurately.

    I hope you like this article. 

    I have a question for you.
    Think about that what is the total energy of the universe?

    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...

    Nitrogen Family: An Incredible Family in the Periodic Table

     Nitrogen Family: An Incredible Family in the Periodic Table  Introduction: Well, all around us there are a lot of atoms, elements, and compounds but we can't notice them. Notice the world around us which influences you. By which we all are made and by which you feel alive. Atoms, elements, and compounds play an important role in this universe.  So, as they are so much important understanding them is very important. Here, comes chemistry which deals with the study of matter, its properties, and composition. Nitrogen Family members: Nitrogen Family members include Nitrogen, phosphorus, Arsenic, Antimony, Bismuth, and Moscovium.  In this, we discuss a lot about its members and explore their hidden properties. So, let's start: Nitrogen: Well, Nitrogen is air. No, I know that air contains other elements and compounds but nitrogen is 78%. That is why I say that air is mostly are nitrogen and I right. Well, you think that if nitrogen is 78% of air then we processed air and...

    String theory: An amazing Theory of Physics

     String Theory: An Amazing Theory of Physics String theory is the theory that answers all the questions of scientists and physicists. String theory may even explain and unite relativity and quantum mechanics and give us the theory of everything which explains all the questions of this universe. Well, string theory is the middle theory that joins relativity and quantum physics, and that explains the major question of this universe.  The major questions that relativity and quantum physics can't explain are: 1. Gravity on the quantum scale. 2. Information paradox 3. Gravity in the black hole 4. Quantum physics can't explain cosmic objects  We need a new theory that accurately explains these questions. To explain these questions humans build many theories which also include string theory. String theory : String theory says that all elementary particle has some kind of vibration. Well, the string thing explains a lot about this universe. But this theory also has some limitatio...
