High School Pedia




It is an initiative by some students to spread the light of knowledge to everyone and everywhere. It was started in the year 2015 and has grown rapidly in the past few months. By the means of this website, we try to provide information on every topic that we can reach up to. You can find different articles on this website. All these articles are written in simple language so that everyone can understand it and learn from it. We at High School Pedia believe in creative learning and this is the reason why we add our own edited graphical representations in every article.


Once a very learned man said, “Knowledge increases by not keeping it to yourself but by sharing it with others”. And we follow the same motto “Share to Learn”. The team of High School Pedia tries its best to provide you with the best and original content. Unlike many other websites, High School Pedia is famous for its original and inspiring content.

SETS, RELATIONS & FUNCTIONS

SETS, RELATIONS & FUNCTIONSSets are a fundamental part of mathematics and it’s knowledge is very important in present. It defines the concepts of relation and functions. These functions are also very essential for present day maths. SETSSets are denoted by capital letters. They are similar to matrices whose elements are denoted by small letters. But in sets an element comes only at once. Sets are matrices which give a sense of belonging. This sense of belongingness is represented by ∈ .We can write anything in a set like rivers of India, Wonders of the World .etc.  For an example let there be a set of positive single digit. Let the set be denoted as A Therefore, 8 ∈ A  Also we can write, 17 ∈ A Set can be represented by two types  ROSTERIn roster form we write elements in curly brackets and separate them with comma.  If there be set of positive integers less than 10. Therefore the set will be {1,2,3,4,5,6,7,8,9}  SET- BUILDER FORMIn set-builder form we take a variable x and then gives its…

Anode Ray Experiment

→Anode ray experiment was conducted by E Goldstein.

→These rays are also known as canal rays.

→This experiment helped in the discovery of the proton.


Apparatus Used A discharge tube was taken in which there were 2 electrodes i.e. Anode(+ve) and the cathode (-ve).The tube was filled with an inert gas.A perforated or porous cathode was used.
A layer of zinc sulphide was placed at the back of the cathode.There was a vacuum pump in the tube.High voltage (5000v-10000v) was allowed to flow through the system.It was observed that when the gas was at 1atm(atmospheric pressure) no change was seen in the tube. When thepressurewas decreased inside the tube, a glow could be seen at the back side of the cathode.

Cathode Ray Experiment

This experiment was conducted by J.J. Thomson (Sir Joseph John Thomson) in the year 1897.This experiment proved that atom is made up of fundamental particles which are much smaller than the smallest atom 'hydrogen'This experiment helped to discover electron.According to J.J. Thomson, the cathode rays consisted of very light, small and negatively charged particles.He named the particles "corpuscles" which were later known as electrons

Android Versions Named After Sweet

Have you ever thought why are Android versions always named after sweet names ??

Everytime a new Android version is launched its name is kept after a sweet name. Many people have researched about this topic and many have asked Google also. Have you ever tried to find out the core reason behind this? If not then you would find the answer here .

First of all let us first see what Google says about this :

In 2008 i.e. the year when Android was launched a reporter asked the reason for the same. At that time Google said

“It’s kind of like an internal team thing, and we prefer to be a little bit — how should I say — a bit inscrutable in the matter, I’ll say,” said Randall Sarafa, a Google spokesman. “The obvious thing is that, yeah, the Android platform releases, they go by dessert names and by alphabetical order for the most part."

Isotopes, Isobars and Isotones

Isotopes

These are elements which have the same atomic number but different atomic mass.They have the same atomic number because the number of protons that are inside their nuclei remains the same.But, they have different atomic mass because the number of neutrons that are also inside their nuclei is different.As the number of protons inside nuclei remains same, therefore the overall charge of the elements also remains same as in isotopes: no of protons = no of electrons.Hence, as isotopes overall charge remains neutral, therefore their chemical properties will also remain identical.Therefore, Isotopes are chemically same but physically different.
