    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...

    HYDROGEN AND HELIUM: WHICH ONE IS BETTER FOR AIRSHIP

     HYDROGEN AND HELIUM: WHICH ONE IS BETTER FOR AIRSHIP

    Hydrogen and Helium are the two ideal elements for airships. The airship was the flying machine famous for transportation before the incident "Hindenburg" occurred on May 6,1937.

    Hydrogen is best in the way that it is lighter than air. It is less costly than helium. But it is very flammable. It's very reactive. 

    Helium on the other hand is heavier than hydrogen and also very costly. But it is inert and non-reactive.

    Kinds of Airship:

    There are three kinds of airship:

    1. Blimp Airship

    There are better options than the blimp type of Airship. It has a single balloon so increasing the lifting gas in the balloon causes it to deform shape. It can't have support.

    2. Semi-Rigid Airship

    Semi-rigid Airship has some support. Increasing its size is easier than Blimp Airship. But up to a certain size.

    3. Rigid Airship

    Rigid Airship has special chambers. So, it is much easier to increase its size, and that is why it is an ideal airship for work and other purposes.

    Hindenburg incident:

    On May 6,1937 the airship was named "LZ 129 Hindenburg" a rigid airship. In this rigid airship, hydrogen is used as a lifting gas. It is 245m in length.

    The incident started when this airship started its journey from "FRANKFURT GERMANY " to "NEW JERSEY USA".  In this airship, 97 people were present of which 36 were passengers and 61 crew members.

    During the landing fire on an airship happened due to the whole airship was completely destroyed. 

    There are two main reasons for this incident:

    1. Static electricity:

    The reason is that due to bad weather static charge built up on the metal frame which causes sparks in flammable gas hydrogen.

    2. Lighting striking:

    The second reason is that lighting causes sparks which cause fire in hydrogen.

    Problem with Hydrogen:

    Hydrogen is the fuel of the future, a dream of renewable but no one discusses the problem with hydrogen. 

    The following are the major problems:

    1. Hydrogen except noble gases reacts with every element of the periodic table.

    2. Hydrogen is very flammable.

    3. Hydrogen embrittlement is the process by which hydrogen causes brittle materials which store hydrogen as atomic gas.

    Problem with helium:

    There are the following problems with helium:

    1. Helium is very expensive and also its reserve is considered in some specific countries only.

    2. There is a storage problem with helium.

    3. Its lifting capacity is much lower than hydrogen.

    Conclusion:

    In this article, we debate which element is the best lifter for airships. Hydrogen has many benefits and limitations same as helium. 

    We also talk about airships, the Hindenburg incident, and much more.

    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...
