I always figured heat is the property of being 'jiggly' at a molecular level, and conduction is when a very 'jiggly' object comes in contact with another object and transfers that 'jigglyness' to the latter.
But how does radiating heat work? That doesn't make sense to me. Is heat a wave? That would explain how I can burn a piece of paper with a magnifying lens, but then conduction does not make sense to me.

Heat is the transfer of energy from one object to another due to a difference in temperature between the two. It is usually divided in three categories: conduction, convection, and radiation.

What you described is conduction, where it is indeed the physical collisions between the molecules of the objects that is responsible for the transfer of heat. In the case of radiation, it is an electromagnetic wave that is the intermediary between the two, instead of collisions.

Thanks, I think I get it now.
