The Geographical North & The Magnetic North

The topic was Magnetism. I started the lesson with this statement:

The Earth we live in is a big magnet itself and do you know that the Geographical North does not coincide with the Magnetic North?

There was silence and blank stares from my 16 year olds. Hello? Anyone there?

The next one hour was spent explaining to them the meaning of Geographical North, Magnetic North, Law of Magnetism and how the forces of attraction work.

A compass is used to show the geographical position but if people have wondered what is it that makes the needle of the compass move to that direction, they would have known the difference between the magnetic north and the geographic north.

I wonder if kids nowadays get intrigued by the things around them. Let me see if Im able to get this theory across to my 4 year old Nephew!

What is "Soul Cryonics"?

Or is it Special "Soul Cryonics" or

"Special Soul" Cryonics ?

And what does it mean and why? When? Where? How? Who?

Just wondering.

Soul is all things good :
compassionate, patient, honest, virtuous and full of love.
Frustration, anger and violence belong to the human body. Our physical form make these qualities inescapable - adapted from a novel
