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.

Levitation 2

To be completely honest I was going to start this with a pun. I did think of one but it doesn’t float…
I am sorry I just had to.
Anyway, this is the second part to the article on super cool ways of making things levitate. Go check the first part out if you haven’t already. Actually, the first part may have become repulsive with all the magnets and stuff, but I promise this will be more attractive. Get it? No? I’ll stop now. I am just going to jump straight into it.
1.Electrostatic Levitation I know you are probably sick and tired of magnets but they are the best way you know… This method is somewhat similar. You remember that cool science experiment you did with two straws attracting or repulsing each other based on their charge? So basically using the same principle we can make a charged object levitate.
But before you try it, let me tell you it won’t be easy. Even impossible according to our Mr. Earnshaw. He even made a law (the law is actually true) stating that you can neve…


You know the classic magician’s trick in which he makes something or somebody levitate? Yeah well, it isn’t magic (obviously!). In fact, there are over 8 different ways in which he can make something levitate. As a side note though, all of the following methods are fairly complicated. In all honesty what he actually probably does is hang the “thing” by a string. You got conned…

What is Levitation? Levitation is flying’s younger brother who was ignored when his elder brother became possible. It’s a sad story… Though in all seriousness levitation and flying are different. So please don’t be a jerk and post a comment saying, “Hey you relic! Levitation is already happening. Have you never sat in a plane before?!” Levitation is (according to Google) and I quote “the action of rising or causing something to rise and hover in the air, typically by means of supposed magical powers.” Way to go Google! I thought we already cleared up that fact that magic isn’t real. So basically levitation…


2-D & 3-D GEOMETRYWe all have some amount of geometry. We know that any line can be represented on the Cartesian plane. Any figure can be drawn on it. But can we represent a 3-d object on it. Yes we can. A Cartesian plane has 2 axis. While representing in 3-D we need to add a third axis. This axis does not come in between the axis or in the same plane. It appears to be coming out of the paper as we cannot represent a 3-d object on a 2-d surface.

This new z-axis represents a line coming out of the screen. Before understanding 3-d geometry you need to imagine this axis coming out of the screen. 
REMEMBER: all the three axis are perpendicular .i.e there an angle 0f 90 between them and they meet at the origin If you are unable to imagine you can take a thick book as an example. Any corner becomes it origin and the three edges as the three axis REPRESENTING 3-D GEOMETRYLike in 2-d geometry we represent the value of the different axis as (x,y) we use the same method to write in 3-d geometry…


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…
