INTRODUCTION WITH TYPES AND QUALITY OF EDUCATION

Education is that the process of facilitating learning, or the acquisition of data, skills, values, beliefs, and habits. Educational methods include storytelling, discussion, teaching, training, and directed research. Education frequently takes place under the guidance of educators however, learners can also educate themselves. Education can happen in formal or informal settings and any experience that features a formative effect on the way one thinks, feels, or acts could also be considered educational. The methodology of teaching is called pedagogy. Formal education is usually divided formally into such stages as preschool or kindergarten, grade school, lyceum, then college, university, or apprenticeship. A right to education has been recognized by some governments and therefore the United Nations. In most regions, education is compulsory up to a particular age. Education began in prehistory, as adults trained the young within the knowledge and skills deemed necessary in their socie...

THE BLACK HOLE

  A region is an object with such powerful gravity that nothing can shake it, including light. The black hole's mass is concentrated during a point of just about infinite density. this is nothing but singularity. At the singularity, gravity is almost infinitely strong. it crushes normal space-time out of existence. As the distance from the singularity increases, its gravitational influence reduce. At a particular distance, which depends on the singularity's mass, the speed needed to flee from the region equals the speed of sunshine. This distance marks the black hole 'horizon', which is like its surface. Anything that passes through the surface is trapped inside the black hole. Black holes are available several varieties, counting on mass. black holes are formed due to the collapse of large stars at the end of their life cycle. Does OUR SUN BECOME A BLACK HOLE? no, why means read the following data carefully. Our Sun is really too small to finish up as a region. ...

THE HISTORY OF PERIODIC TABLE

The periodic table is invented due to avoid confusion while searching and locate the elements. at that time chemists are started to frame ways to group these elements and compounds on the basis of their physical and chemical states. at the beginning of the 18 th century, a scientist called joseph Louis stated that the hydrogen atom is a building material and atoms of all other elements are simply due to a combination of a number of hydrogen atoms. and also considering some examples the atomic weight of hydrogen is taken as ONE. DOBEREINER'S TRIAD THEORY: dobereiner's he was a German man. he was tried to prove the relationship between elements of their properties and atomic weights. he stated that the arrange the three elements are in ascending order which has similar properties with the help of atomic weights. and the middle element is the average of the first and third elements. this theory is called the law of triads. limitations: this law failed for low mass and very high ma...
