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.
https://youtu.be/5ullKA0eUoo

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

2-D & 3-D GEOMETRY

2-D & 3-D GEOMETRY We 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 GEOMETRY Like in 2-d geometry we represent the value of the different axis as (x,y) we use the sa...

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.       π (pi) or Archimedes constant (~3.14159):   π is defined as the ratio of the circumference of a circle to its diameter. This is probably the most popular mathematical constant. So π 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 (πr 2 ) or the circumference of a circle (2πr). It has many uses throughout mathematics from calcula...

Animal and Plant Cells

 Cells Cells are the basic functional, biological and structural unit of life. The word cell is a Latin word meaning ‘small room’. Cells are also known as building blocks of life.  The branch of science that deals with the form, structure, and composition of a cell is known as Cytology. All organisms around us are made up of cells. Bacteria, ameba, paramecium, algae, fungi, plants and animals are made up of cells.  Cells together form tissues. And tissue together makes an organ. History Of Cell The cell was discovered by Robert Hooke in 1665. He assembled a simple microscope and observed a very thin slice of cork under his primitive microscope. The cork was obtained from the outer covering of a tree called bark. Robert Hooke observed many little-partitioned boxes or compartments in the cork slice. These boxes appeared like a honey-comb. He termed these boxes as the cell. He also noticed that one box was separated from another by a wa...

Pareto’s Principle

PARETO PRINCIPLE The world is not fair. It is extremely unequal. Some people get everything and others nothing. You know what the craziest part about this is? This inequality is mathematical. As absurd as this may sound, there is a phenomenon, rather “principle” to describe this, The Pareto Principle. If I change my opening statement to, 20% of the people get 80% of everything and the others only 20% of everything this statement becomes a perfect example of Pareto’s Principle. It may be clear already but the Pareto principle basically states that, for many events, roughly 80% of the effects come from 20% of the causes, and hence is also called the 80/20 rule. I realize that so far this may be ambiguous. So let’s explain this the classical way, with examples! Vilfredo Pareto An economist (quite obviously the guy who demonstrated this principle) originally noted this effect in his garden. With peapods . Math doesn’t always have to be nerdy and theoretical. ...

Acceleration Due To Gravity (g)

Acceleration Due To Gravity (g) All objects are attracted towards the earth by a force which is called The force of gravity . This force produces an acceleration which is called acceleration due to gravity and is denoted by 'g'. The value of 'g' on the surface of the earth is 9.8m/s^2. 'g' is an extremely important constituent of Physics and most of the Physics numerical problems involve the usage of 'g'. Effect of The Shape of Earth on 'g' 1)Earth isn't a proper sphere, it's a geoid ( flattened at the poles ) 2) g = GM/Re^2 The radius of the earth is lesser at the poles than the equator Therefore, the value of 'g' will be more at the poles, ( according to calculations, by 0.018m/s^2, it will be more ) Variation In 'g' We take the magnitude of 'g as 9.8 in general, but the value of 'g' varies:- 1) IF THE OBJECT IS ABOVE THE SURFACE OF THE EARTH, g(at h) = g(1+2h/Re) 2)...
