🏞️ Green Revolution 🏞️ The Progress in Agricultural Sector...  * Green revolution :-      " To the use of pesticides and techniques increase the productivity of food grains such as rice and wheat, due to the introduction of high-yielding varieties ."         In 21st century many countries are developed, some are  developing but at time population is increase due to this the food, vegetable quantity relatively low because all farmers cultivate land by using the methods of traditional.        The increase in population is directly stress on the agriculture field to reduce it's stress increase the productivity is most important thing.      In mid-20th century, This problem of  solution is finder by  Norman Borlaug , Norman Borlaug also known as  ' the Father of the Green revolution ', he  introduce  term Green revolution to  the world. Is the best turning point of the agriculture field...........     M.S. Swaminathan plays an important

What mean by Units......? Unit is the basic part of the measurement, because without unit we don not measured anything. Unit:- The reference standard used for the measurement of a physical quantity is called a Unit. System of units:- C.G.S. M.K.S. F.P.S. S.I. units :-            Use of different system of units became very inconvenient for exchanging scientist information between different parts of the world.     Hence, in October 1960 at the Eleventh International General Conference of weights and measures, in Paris, a common system of units called  "System International d' Units"  was accepted.         This system of units called S.I. units consistent of seven fundamental units, two supplementary units and large number of derived units.      Units are classified into two  groups    F undamental units  and  Derived units . The seven basic physical quantities: Length, mass, time, temperature, electric current, lumino

Basic and Important term of  Physics Measurements           Physics is a basic discipline in the category of Natural Science which also includes other disciplines like Chemistry and Biology .  In Physics , we attempt to explain diverse physical phenomenon in term of few concepts and laws.           Basically there are two domain in the scope of Physics : Macroscopic and Microscopic . The Macroscopic includes phenomena at the laboratory, terrestrial and astronomical scales.  The macroscopic phenomena deals mainly with the branch of classical mechanics which includes subject like mechanics , electrodynamics, optics and thermodynamics.  The Microscopic domain includes atomic, molecular, and nuclear phenomena. The microscopic domain of physics deals with the constitution and structure of matter at the minute scale of atoms and nuclei and their interactions with electrons, photons and other elementary particles. The scope of physics is truly vast. It c

 * Acid and Base * Acid and Base are the concept of chemistry but in every day like it is important.  For example, after getting of more amount of lunch or dinner we says , 'enough, excess amount of food, produce acidity'. Some time stomach produce Gas at that time we get lemon drink, some time we get soda. This is common every day life use of acid and base. But the machanism behind this, stomach produce more amount of digestive liquid this liquid is acidic, for minimize this we get antacid or soda like basic component. What is acid?                              What is base ? And chemistry behind this let's start with acid. * Acid The word acid is derived from Latin word acidus . Acidus means Sour. The general taste of Acid is Sour. Acid definition ÷  The substance which produces  H+ ion in aqueuse Solution is called as Acid . Properties of acid ÷ Acids are liquid.  Taste of acid is Sour. The aqueuse Solution of acid conduct ele

🌴Plant cell and Animal cell🐂 The cell was Discovered by Robert Hook (1665). Plant cell and Animal cell  boths are  Eukaryotic cells . They have true and well developede Nucleus. Plant cell   and Animal cell have several similarities.  Plant cell ÷ * Plant cell diagram Plant cell is big than animal cell. Plant cell store energy in the form of starch. Plant cell have cell wall ,it's acts as a outer protective membrane ,support the cell and provide the shape of cell. They have large vacuole. Animal cell ÷ *Animal cell diagram  Animal cell is smaller than plant cell. Animal cell store energy in form of complex carbohydrate glyacogen. Animal cell do not have cell wall. They have small vacuole.

🎀 Type Of Cell 🎀 In past some articles are on cell theory, what is cell..? And other cell related concept we read.  all cells are same but the chemical structure and shape of cells are different in different organisms. The organization of the organizams depends upon the cell, because cell is the basic structural and functional unit of life. *There are Two Types of Cell ÷ Prokaryotic Cell. Eukaryotic Cell.  *Living organisms are grouped into two main categories, the Prokaryotes & Eukaryotes . The Prokaryotes have simple cellular organization. The Eukaryotes exhibit high degree of organization. Prokaryotic Cell -    Definition of Prokaryotic Cell- Pro means Primitive and Karyot means Nucleus. In simple words , the cell do not have well developed Nucleus is called Prokaryotic Cell. Structure of Prokaryotic Cell- The Prokaryotic Cell do not have True nucleus.  nuclear material is not bound by a definite nuclear membrane. the Prokaryotic C

💫PHOTOELECTRIC EFFECTS 💫 * Photoelectric Effect Definition ÷  The phenomenon of emission of electrons by certain substance , when it is exposed to radiations of suitable frequency is called as " Photoelectric effect " " Photoelectric effect was discovered by Heinrich Rudolf Hertz in 1887" .    * Experimental study of Photoelectric Effect ÷ Aim : To verify the phenomenon of photoelectric effects.  Photoelectric effect apparatus : Evacuated glass tube having Quartz window, photo sensitive plate, metal plate, voltmeter, microammeter, commutator, battery. Photoelectric effect experimental setup {arrangement }: Observation  :  the Hertz experimental arrangement of photoelectric effect is shown in over above. Setup the apparatus complete the circuit as similar to the diagram .It consists of an evacuated tube having photosensitive plate 'C' and another metal plate 'A' .Monochromatic light from the source 'S

🌅PHOTO-ELECTRON🌅 * Photoelectrons ÷               "  The phenomenon of emission of electrons by certain substance , when it is exposed to radiations of suitable frequency is as Photoelectric effect and the emitted electrons are called Photoelectrons "  . Photoelectric effect is a one photon-one electron phenomenon.  One photon cannot eject more than one photoelectron . 'The  phenomenon of photoelectric emission ↖ύ was discovered by Heinrich Hertz {in 1887}'. Hertz and Lenard's discovered the photoelectric emission.  He observed that spark gap conducts electricity more easily when it is illuminated by ultraviolet(UV) light from arc lamp.  Hallwachs and Lenard investigated phenomenon of photoelectric emission in detail (1886-1902). *Science world*

💫ELECTRONS AND PHOTONS💫 In 1897, sir J.J. Thomson       Found that negatively charged particles namely Electrons .           " The discovery of electron can be considered as the starting point of the development of modern Physics ". * Photons ÷          " The packets of light energy (Quantum) of electro-magnetic radiation. "               Each quantum of light is called Photon  .   "According to the Maxwell's quantum theory, modern concept of Photons was developed by Albert Einstein ". The energy of photon is E=h√ Where '√' is frequency of light and 'h' is Planck constant. *Science world*

💫 CELL THEORY 💫 We know cell is the basic, structural and functional unit of life. This sentence was clear by the cell theory. Cell theory clear the all misunderstanding of cell. Cells are combined and form life. Human, animal and plant body is made up of cells. After the discovery of cell some problems and misunderstanding remain as it is, this all clear by scientists schleilden and Schwann they propose the cell theory which include the proper introduction of cell, cell existence and function. * Cell theory  ÷           " The simple,basic and formal biological generalization is known as ' Cell theory ' or ' Cell doctrine' . " M.J. Schleiden and T.S. Schwann established the cell theory in definite form.  These two investigators are known as the " Founders of cell theory ". # Postulates of M.J. Schleiden and T.S. Schwann  Living matter exsits in the form of essentially similar unit cells.  Cell is the basic structural

🔬 Cell 🔬   Cell is the main concept of biology.  Before the recovery of the cell people don't know what is the basic unit of life......?Human made up of...? Live or non-living matter means...? Etc Like questions are motivated to scientists.  Robert hook , see the cork bark under the microscope he saw some compartment like structure, but this compartment are empty because he saw the dead cork bark. Robert hook start the further invention and other scientists contribute to the discovery of the and and finally, today we know that all about basic concepts of cells. * Cell ÷ "  the smallest constituent of the body is called cell "  All living organisms are made-up of Cell .   Cell it is a Stuctural and functional unit of life. The term cell has been derived from the Latin ward " Cellula " The cell was first introduce by Robert hooke (1665) Later , Antonie van Leeuwenhoek  {Father of microbiology}   pursued microscopy and existence of

⚗️ SOLUTIONS ⚗️ In the every day life we make tea, coffee, soups....etc....etc it's nothing but the solutions. In chemistry language The product formation after mixing of two or more than two components is call as the ' solution '. * Solution ÷" Solutions are the mixture of two or more than two components ". Depends on the size of the components, solutions are classifieds into three types ÷ A} Coarse mixture ÷ it is formed when the sizes of the constituent components are relatively bigger , E.g. - mixture of salt and sugar. B} Colloidal dispersion ÷ it is formed when the size of particles dispersed in solvent are are in the rang of 10^-7 to 10^-4 cm . Colloidal solutions are heterogenous ,can easily separated. E.g.- arsenic sulphide solution. C} True solution ÷ the true solution is formed when soluble substance are dissolved in solvent. The size of the particles dissolved are very small . A true solution are homogenous , can't

🔍 THE CHEMICAL EQUATION  🔎               We know ,the chemistry is incomplete without Reactions , Chemicals and Solutions . So to clear the concepts of chemistry first we starts from the chemical equation and the content of equation . The term equation is mostly used in the maths but chemistry is incomplete science without chemical equations. In the maths we solve verious types of the equation some time its hard, easy and some time difficult due to the formulas. But in the chemistry the chemical equations are easy and most important because they depends on only one formula. In short, we know every one the chemistry is the Science in which some elements reacts with each other and form new product it's common concept of chemistry arrenged in the mathamatics solutions and find the answer is known as chemical equations. *THE CHEMICAL EQUATION* " The chemical reaction represent in the symbolic form is called as Chemical Equation " Example,               

💫 Newton's  law of gravitation   💫 Sir Isaac Newton defined what is gravitation, how is work and all concept by the law , this law of Newton is known as ' law of gravitation '. The Gravitation law, defined some terms and one gravitational constant. #Law ÷.                                                                              "Every particle of matter attracts every other particle of matter with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them " Where,            'G' is a constant which is known as " Universal Gravitational Constant " .           The gravitational force between two particles act along the line joining the two particles and they form an action-reaction pair . The force exerted by first particle on the second is equal and opposite to the force exerted by the second particle on the first . *The va

💫 GRAVITATION  💫    The constituents of the Universe are Galaxy,Stars,planets,Asteroids,Meteoroids ,black holes ,White dwarf,Meteor ,etc .  The moon revolving around the earth and all planets around the sun how is it possible, without any bonding without any support how is it possible?       Sir Isaac Newton fond the solution of this all questions.          One story of the sir Isaac Newton, he is seating below the apple tree and suddenly one apple through down to the ground,  Therefore Great mathamatisian sir Isaac Newton start to finding all the questions like why the apple is down to the earth, it's do not through the up on the sky??????? And the Newton find the Gravitation....               "The force which keeps them bound together is called " GRAVITATIONAL FORCE "               " Gravitation is the force by which material objects are attracted towards one another". In 1687 , Sir Isaac Newton published principal Mat

                    * The   Atomic   theories *    The atomic theories are the best successful contribution of the scientists, because it's gives most important information, some properties and the concept of atom.    Before the atomic theory some misunderstanding related to the atoms are created. Scientists find this misunderstanding and solve the all problems related to the atoms by giving the atomic theory to the world. All the concept of the atom are clear with the atomic theory. Dalton atomic theory :-   John Dalton proposed that all matter is                 composed Of small ,Hard,Indivisible particles called "Atom" . Atom of given element are identical and have characteristic mass. Atom combine to form a molecule.                     Thomson atomic theory :-        J.J. Thomson discovered Electron .        According to Thomson, atom consist of                 positively charged sphere with negatively                 char

In Last article We Define  Atom ,  Molecules  & Nuclei.  And the molecule    Atom and atomic concept is the very interesting part and it's not just interesting but important part for chemistry, physics.    Atom is considered as the basic and fundamental unit of the molecule or elements.    Atom is the important back bone of the chemistry, because no one any chemical compound is made up of without atom. Atom is the basic , fundamental and functional unit of the elements is not wrong.     Atomic model and atomic concept of the atom, Scientists gives verious information and the reality of the atom. For the extra and proper information, some scientists like J.J. thomason, John Dalton, and Rutherford gives the atomic theory, due to which the concept of atom for understanding is very easy. Before the atomic theory, we start the concept related to atom.                *  The Concept Related to Atom * In 1808 , John Dalton performed an his experiment and prove that

                                    💫 ATOM 💫 The most intrasting part of the factors of science is ' Atom '.  Atomic theory and atomic model gives the concept of atom and it's it's structure.  # In chemistry atom is the basic component of the element.     We know every element made up of atom. But some time we don't know about the atom , what is atom...? What is combination of it is....? How they stable ....? Atom is the smallest part of the elements but some particles they consist due to which they stable in their structure...     In past, verious Scientists find this concept and contribute to the reserch of atom, atomic model and atomic theory.          We know the Scientists John Dalton, J.J. thomason, Rutherford they are great contribution for the atomic theory and finding the concept of atom. #  John Dalton known as " the Father of atomic theory". So let's start to concept of atom. # Atom consist of _ 1} Positively ch
