Teaching using analogies can help us understand complex scientific concepts better. By comparing the micro world to the macro world, we can make difficult ideas easier to grasp. For example, thinking of electricity like a fluid helped Tesla make important discoveries. The talk discusses how analogies can explain how charge moves in different materials, like cars on a highway. This model can also help us understand how electronic devices work, like transistors and photocells. Analogies are a useful tool for understanding the invisible world of quantum mechanics.
