I am now in a class where the lecturer is talking about the critical radius for the nucleation of a bubble, simply means how much forces are needed for a bubble to be formed in a pool of boiling water. 

We need to know the critical radius comes when surface tension force = net pressure forece. 

Do i sound like i understand anything about this? Or do i even sound like i care? 

im bored. 

Interesting me.
