This vacuum tube-based analog computer solved complex mathematical equations by using varying electrical voltages instead of 1s and 0s like a digital computer. In science and engineering, analog computers model a large range of real-world phenomena, like missile trajectories, spacecraft design, economic policies, and even flight simulation. By the 1970s, digital computers displaced them, offering precision, reproducibility, and versatility that analog technology could not match.
