    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...

    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 limitations like, it has many versions. String theory has multiple versions like Type I, Type IIA, Type IIB, and heterotic strings. Its explanation needs many dimensions which add complexity to its calculation.

    String theory is important for humanity because it tries to explain to us the reality of nature. 

    What is the theory of everything?

    The theory of everything is the theory that explains to us all the questions of this universe from the cosmic level to the quantum level and many other secrets after the theory of everything when understanding gravitational force a lot.

    white string vibrates with black background

    String theory Explanation:

    Imagine you have a microscope that zooms small enough that we see smaller building blocks. Then according to string theory, the smallest building block of this universe is strings that vibrate at a specific frequency and each frequency represents specific elementary particles like quarks, meons, tau, etc.,

    String theory explanation needs dimensions. How many? So, string theory has multiple which has its unique identities but the basics are the same all theories are based on strings and vibrations but all these theories have some differences some assume 11 dimensions some assume 26 dimensions, and so on.

    String theory is critical because it gives us graviton which is a particle responsible for gravity on a quantum scale also known as "Quantum Gravity" which connects quantum theory with relativity thus we have the "Theory of everything " which explains all the questions necessary for understanding the working of universe.

    The particles that string theory predicted are:

    1. Graviton which we explain early.

    2. Supersymmtery particles: According to string theory each particle in the standard elementary model has some kind of superpartner. For example, electron superpartners are "selectron",  tau superparticles are "stau" and muons superparticles are "smuons".

    3. Extra bosons and fermions: String theory describes some extra fermions and boson particles. For example, axions and dilatons.

    Conclusion:

    In conclusion, String theory is a theory that may be a step toward the "Theory of Everything" which gives us answers to all our questions about this universe and so on. 

    I hope you learn a lot about science and physics.

    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...

    HALOGEN FAMILY: THE MOST REACTIVE FAMILY OF THE PERIODIC TABLE

    HALOGEN FAMILY: THE MOST REACTIVE FAMILY OF THE PERIODIC TABLE Introduction: The halogen family contains fluorine, chlorine, bromine, iodine, and astatine. These elements are know for their reactiveness. This family contains many reactive elements known including fluorine which is one of the most reactive non-metals in the periodic table.  We are starting to talk about this family and its unique properties which blow your mind.   So, let's start: Fluorine: Fluorine is a very reactive non-metal. It is because of the fact that it has higher charged nuclei which are not shielded by electrons. That is why it attracts other element's electrons and thus forms compounds with them. Properties of fluorine: There are the following properties of fluorine: 1. Fluorine as discussed earlier is extremely electronegative which means it attracts electrons of other elements. 2. Fluorine is a highly reactive element. 3. Fluorine is very toxic and causes many disorders in the bodies of anima...

    Nitrogen: Cool Element very Important for Life

     Nitrogen is a very useful and abundant element in the atmosphere. About 78% of the atmosphere is composed of nitrogen elements. Nitrogen is a quite chill and cool element. Joke about Nitrogen: A scientist took a selfie while he was drinking liquid nitrogen He was quoted as saying "It was the coolest shot I ever took" Properties of nitrogen : Molecular weight: 14.01g/mol Boiling point: -195.795 degrees c Melting point: -210 degrees c Density: 1.251g/L Appearance: Colourless gas(at room temperature and pressure), Colourless liquid and solid. Isotopes of Nitrogen: Nitrogen has two stable isotopes N-14 and N-15. N-14 is the most abundant element in the atmosphere at 99.6% and N-15 is about 0.4% of this atmosphere. Each isotope has its own use for scientific and engineering purposes. Nitrogen Cycle and Nitrogen Fixation: First, all games start with atmospheric nitrogen which is composed of about 78% of the total atmosphere. But there is a problem plants and animals can't use ...
