Levitation 2

LEVITATION II


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 never find a stable equilibrium point where the charges completely counteract each other, so the levitating effect created my magnets, electrostatic forces (those are somewhat similar) will be “chaotic” unworthy to be called levitation in the eyes of a true physicist. And then he twirled his mustache. Just joking, I made that last part. Just checking if you are still awake.

But the other physicists did not shy away. Any coders here? If yes, then you know what a Feedback Loop is right?

(For the non-coders, a feedback loop is something that sort of fluctuates, giving rapidly changing commands taking into the system’s output into consideration to achieve the desired outcome)
So the scientists basically created a feedback loop to detect the object’s position (if it was too high or too low) and manage the charge accordingly.

2.  Aerodynamic Levitation


This is probably the most intuitive way. Ever seen a floating table tennis ball on a hairdryer? Yup that is a perfect example. If you haven’t ever seen that, get a life dude/dudette. But seriously do it for yourself. Unlike the other things this is not a trap, you can actually do it!








Helicopters, Air hockey tables both work on this principle as well. The super cool wind tunnel type things that make it as if you are skydiving also use this. So you can technically levitate. Unlike the other methods this one is actually being used and has applications.

Also just so you know, Gas film Levitation and this are practically the same. There is a little bit of difference but let us avoid going into those details…

3.   BUOYANCY LEVITATION

This is sort of a cheaty one. Helium balloons are sort of similar. Helium balloons rise up because helium is lighter than air. So imagine if there was a point where suddenly air stops and helium starts. If you keep a box (Since this is physics, we are allowed to assume that the box has no mass) filled with Helium at that point, it would appear as if the box is floating.

Whoa! I suck at explaining… Let me make this simple. Paper floats on water. Floating and levitation are essentially the same thing. We just don’t call floating as levitation because the object is in contact with the ground via water. Technically when anything levitates it is also in contact with the ground through air… Riddle me that Science!
I googled, I was wrong. Levitation is called such if it is possible in a vacuum. Therefore we can call magnetic and electromagnetic and all other methods as true ways to achieve levitation as vacuum or not, it does not affect them.

Coming to this method, if you have a gas with a different density than that of air, you can achieve levitation (not scientifically though since this won’t work in a vacuum where nothing is between the object and the ground)

This video should help understand. It shows a light open box seemingly “levitating”. The truth is it is floating on xenon (gas with high density) which is heavier than air so it does not leave the transparent container.

Another method that can be used to create levitation is difference in density of air molecules in an area, creating a pressure that could make an object levitate. The only problem is that since it relies on a sort of contained area or some sort of support it is not exactly true levitation. It’s called pseudo levitation (pseudo meaning false). There is something known as a vacuum elevator that could help explain it. Just watch the following video because I realize I did not make a lot of sense.

Just as a side note, this method relies on buoyancy of air. Hence the name.
As usual I have crossed the word limit so I am going to have to leave you here and leave the coolest parts for the next article. I sincerely hope this was more interesting than just magnets and if you don’t agree, nothing you can do about it. #getrektm8

Important Mathematical Constants!

Important Mathematical Constants Mathematical constants are those numbers that are special and interesting because they come up in the various fields of mathematics like geometry, calculus etc. These mathematical constants are usually named after the person who discovered it and they are represented by a symbol that is usually picked up from the Greek alphabet. Mathematical constants are by definition very important. In this article we will take a look at certain mathematical constants that are more commonplace than others. 1.       Ï€ (pi) or Archimedes constant (~3.14159):   Ï€ is defined as the ratio of the circumference of a circle to its diameter. This is probably the most popular mathematical constant. So Ï€ is the circumference of the circle whose diameter is 1 unit. You might have seen it popping up when calculating the area of a circle (Ï€r 2 ) or the circumference of a circle (2Ï€r). It has many uses throughout mathematics from calcula...

Permutation and Combination

Permutation and Combination Hey guys, I am back with one more interesting mathematics topic. And I am pretty sure that you guys would find it interesting too because many of you must have faced problems regarding these arrangements. Although if you were not able to solve them at that moment of time I am sure after completing this article you would solve the problem in minutes or even seconds. WHAT IS THE DIFFERENCE ?? Many people get confused between these two terms permutation and combination. They both have almost similar use but have a vast difference in their meaning. You may think that both of them mean arranging entities, then what is the difference ?? For making it easy we will take an example, lets say I have four friends : Arya, Bhavesh, Chirayu and Dhruv. So if I arrange them like Arya, Bhavesh, Chirayu and Dhruv or Dhruv, Chirayu, Bhavesh and Arya, it will make no difference in combinations but if you check them according to permutation they will be different. As ...

Rutherford Alpha Ray Scattering Experiment

Rutherford Alpha Ray Scattering Experiment Hey, Guys, most of you might have heard about the alpha ray scattering experiment and if you want to know in detail about Rutherford's model and the experiment he conducted, this is the right place for you... But first: Things You Must Know Some basic information that will help you understand rutherford experiment properly: Proton is a sub-atomic particle which is positively charged and has a mass of 1u. Alpha particles are helium atom with a charge of +2 as they have lost 2 electrons. Alpha particles have an atomic mass  of 4u. Gold is highly malleable and can be beaten into very thin sheets. Experiment Rutherford conducted his experiment in the following way: Rutherford took a very thin gold foil and bombarded it with high energy alpha particles. He placed a layer of zinc sulphide on the walls where the experiment was taking place because when alpha particles ...

LEVITATION 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 rea...

Levitation 3

LEVITATION III Don’t worry no puns this time. And for the final part of this “levitating series”, I bring to you the coolest ideas! They are both scientific and super geeky effects that nobody ever teaches you because they believe that these effects are useless.  But fortunately for you our site exists and we believe in bringing out the cool aspects of science so be prepared to be enlightened and rise (Get it?! That was the last one. Promise. For real this time) to attain scientific nirvana with: Meissner Effect This also has to do with magnets. I am sorry. But I promise this will be cool. This method involves a dipolar magnet on top of a superconducting substance. What essentially happens is that when a substance becomes superconducting, that is, it has no electrical resistance whatsoever, all magnetic field through it get expulsed (removed). At the same time, eddy currents (What are eddy currents? Trust me, you do not want to know. They are some weird quantum thi...
