Electronics intriguingly mimic the human nervous system, with circuits resembling neural pathways. Transistors, the building blocks of modern electronics, act like synapses, switching and amplifying signals to facilitate communication within devices. Invented in 1947, they revolutionized technology, leading to the miniaturization of circuits and the birth of the digital age. Every smartphone today contains billions of these tiny switches. Marvel at the microcosmic world inside gadgets and share what fascinates you about the electronic symphony that powers our lives!
