Materials show varying behaviors based on their Poisson's ratio. High Poisson's ratio materials (near 0.5) contract significantly sideways when stretched and expand when compressed, seen in substances like rubber. Low Poisson's ratio materials (near 0) undergo minimal width change during axial deformation, typical of metals and common engineering materials.

The speed of light does not depend upon the temperature of air but the speed of sound depends on it. Why?

As we know that wave of sound is a mechanical wave and its speed is given by

v = (γRT/M)

whereas the wave of light is an electromagnetic wave and its speed is given by

c = (1/εoμo) 

So speed of sound depends on temperature of air but speed of light doesn't.

There are different ways to visualize infinity to ponder upon. This is some random thing about infinity in my head which I'll be mentioning.

Imagine any number, Keep on adding a certain value to it, Since we are talking big here, there is no limit to how much you add.

Keep on adding, Imagine that the progress of increment is like a progress bar. So, Is the progress bar really progressing? Since it doesnt really have an end and no...
