Levitation 3


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:
  1. 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 thingamajig) are produced in a manner that opposes the magnetic field/pole of the magnet above it. This repulsion causes the magnet to levitate. The best part, Earnshaw’s law does not make this complicated. Because as the point of equilibrium (the point where he charges completely cancel each other out) moves, so do the eddy currents to oppose the magnet. It is self-sustaining! This video should help explain it a bit better.
  1. Leidenfrost Effect
This is not technically levitation but since it is so cool and has nothing to do with magnets, I had to include it. I doubt you have ever seen what happens to water droplets on a super-hot pan. But if you have you have already seen this effect practically. This method works with all liquids. When a liquid comes into contact with an object which is significantly hotter than its boiling point, the bottom of the liquid becomes so hot that it starts vaporizing forming a layer of vapor below the liquid that causes it to “levitate”. This levitation is highly unstable though. You will see what I mean in the following video.
Crazy right? But this is not the only way it can be visualized. What if an object above the Leidenfrost point (temperature at which the effect occurs for a certain liquid) is dropped into the liquid? Let us see!
This effect has incredible possibilities. When the droplets experience this effect, they encounter minimal friction, causing even the smallest of stimuli to make them move around very fast. If this motion could be controlled, possibilities are limitless!

That finally concludes my article on different levitation techniques. 
But before I end this article, I would like to completely baffle you. It is actually possible that we cannot actually even touch anything else (article on that will come soon) due to some crazy quantum physics on a subatomic level. Wouldn’t that mean that we are not really ever in contact with the ground? Doesn’t that mean that all things including the monitor you are reading this article on and you, are levitating?

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 wall. What Ho

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 strike zinc sulphide layer, it results i

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.

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
