Magnetism is Just Electricity in Another Frame

 Recently, I came across something that shook my whole understanding of electrodynamics. I had studied the different electric and magnetic fields their interactions and how one (quite mysteriously I might add) transforms to the other. A moving charge creates a magnetic field. A change in the magnetic field causes a current. Why do these different fields just change into each other based on the relative motion of their sources? The answer lies in special relativity. Rigorously of course, one could prove that the magnetic field is just the electric field in another reference frame using the relativistic transformation of the fields however, the setup that gave me intuition and helped build the idea is deriving the Biot Savart Law from special relativity. \[B =  \frac{\mu_0I}{2\pi r} \] The setup Take an infinitely long wire, we aim to find the force on a moving charged particle adjacent to such a wire. Of course, the force is\[F = qv \times B\] But consider this, what causes the...

Cloning, Biological and Physical.

 If you are a science fiction lover, you must have dreamt of cloning, but have you ever wondered how does cloning work and what are its dangers? Believe it or not, cloning was real, but not the cloning you would imagine, but biological cloning.

In 1996, dolly the sheep was successfully cloned by fusing the nucleus from a mammary-gland cell of a Finn Dorset ewe into an enucleated egg cell taken from a Scottish Blackface ewe. Biological cloning is almost like passing down of genes from parents but is performed in laboratories.

 Recent studies have shown that genetic engineering, which is recent technology can remove the child is prone to inherit from the parent thus making a "perfect child" it seems cool and nice for sometime after you hear it, but it is an horror as it takes away all your individuality and personality and leaves you as a child shaped robot.
Wait, that's getting too much into biological cloning, let's  discuss physical cloning, which means everything same to the subatomic level, the charge, the spin, the position, etc. The method best candidate for physical cloning is a machine that measures all the features of the main body you want to clone and arrange some raw materials in the very same way. 

Even though it sounds so, it is not so easy as there are some problems and the major one is lies in the Heisenberg uncertainty principle-                                               
 

The Heisenberg uncertainty principle states that at the subatomic level, the more the certainty in the speed of the particle, atom, or molecule, the more uncertain the position the object, vice versa. There is but one solution to this problem that we take a number of the same thing, all identical even to the subatomic level, and then we measure different attributes of the object on individual objects eg. Measure height in one, weight in one, position in one and speed in one, etc.
 

 

But don't get your hopes up for physical cloning as getting these completely identical objects is impossible in today's understanding, and don't try any type of cloning as it is very dangerous and certainly don't try to alter personalities as it destroys the value of human individuality.
