Randomness

SciShow Tangents

Is all life predestined, or is existence blown about by the whims of entropy? If we restarted the universe with the same world generating seed a la Minecraft, would it all play out the same??? These are ginormous questions that we do not get into in this episode! Instead, we're examining slightly more manageable examples of randomness in nature, in computing, and even in ourselves.
